Image Processing Automates Eyeglass Fitting for Rodenstock

http://mvrpl.com

Imagine that you wear varifocal glasses and need new ones. You go to an optometrist and, without time-consuming adaptations, measuring or trying on frame after frame, you look at yourself in a mirror and - voila! - your chosen frame is on your nose.

Automatic calculation of eyeglass frames and lenses enables customized fit 

International eyeglass manufacturer Rodenstock GmbH of Munich has developed an optometrist service terminal that can do just that. It enables automatic calculation of eyeglass frames and lenses customized to fit an individual's face - all in about a second. 

The terminal, called the ImpressionIST, performs several tasks. It provides interactive information about the eyeglasses, presents frames from which the customer can choose, calculates the ideal dimensions of the glasses via a three-dimensional video system, and offers consultation regarding the quality of the glasses. The technical requirements of the system are targeted to the aesthetic aspects of choosing glasses.

Exacting images

The patent-pending 3D video system, which measures the customer's face, must make the fitting procedure as easy as possible. Thus, the 3D measurements are done with the customer looking into a semitrans-parent mirror that is 75 cm away. The imaging system, mounted behind the mirror, is hidden from view. It uses two cameras from Allied Vision Technologies to take images simultaneously. After the measurements are concluded, the optometrist can go over the images with or without the customer.

One camera captures the face from the front and the other, from below and the side (Figure 1). These create aesthetically pleasing images, while being suitable for analysis.

The images are processed based on the software library HALCON from MVTec Software GmbH of Munich. The software delivers the real-world 3D coordinates necessary for manufacturing the frames and lenses. By acquiring a calibration plate before the first start-up of the ImpressionIST, inner and outer camera parameters can be appointed to deliver the coordinates.

The analysis begins with a position cross mark placed at each pupil's center on the image of the front of the face (Figure 2). The software uses information about the camera position, illumination and reflection from the cornea to calculate the centers.

To make measuring as comfortable as possible and to ensure the customer's elemental posture during image acquisition, no flash is used. For this reason, three 11-W lamps from Osram are integrated into the system, arranged to find the pupils' centers from the reflections on the corneas. The showroom should be illuminated with diffuse light.

The final position can be adjusted by the optometrist. The brims of the glasses are computed by edge extracting each glass's front. Other cross marks are positioned at the point where the extensions of the straight lines through the pupils' cross marks meet the brims. These marks also can be adjusted. The same positions are determined for the image from the other camera, and the already adjusted cross marks from the front image are projected onto it (Figure 3). Then, the cross marks can be automatically transferred into each other.

For Rodenstock, it was important that the optometrist maintain the ability to adjust the positioning, although the image processing software could do it. After the optometrist approves the positioning, the 3D coordinates of the corresponding cross marks are computed, taking the calibration into consideration.

The computation delivers all the parameters needed to manufacture the frames, including monocular pupil and corneal vertex distance, pantoscopic tilt, face-form angle, fitting point height, decentration (of the fitting point), boxed data (lens width and height), distance between lenses, frame shape and optimized lens diameter. The results are documented in a hard copy that includes illustrating figures and that is optimized to allow grinding of the lenses.

Rodenstock's tests of the system by Rodenstock have found that the measurements are accurate and repeatable, depending on the customer's ability to repeat a position. The reproducibility using the system was 1.5 times higher than when using a free distal view. 

The system is currently available only for Rodenstock consultant optometrists.

Switching from CCD to CMOS Cameras

http://mvrpl.com

Sony has announced the closure of its CCD sensor factory. CCD camera users are now confronted with questions around switching to CMOS technology and the availability of current CCD camera models.
For us, the move toward CMOS technology doesnt come as a surprise. We started our preparations some time ago and can offer a broad portfolio of CMOS products. 

Sony has scheduled the last delivery of the CCD sensors that are integrated into Basler cameras for the end of 2026. Basler will ensure a smooth transition from current Basler products with CCD sensors to CMOS sensor-based Basler products.
 
We have put together a list of answers to the most relevant questions around this transition and around suitable successors for your CCD sensor-based Basler ace camera.

CCDs been discontinued. Now what?

Experience together with Steve what Sonys CCD discontinuation announcement means and how you can deal with it.


FAQs

When should I begin switching from CCD to CMOS?

In general, you could start any time. Switching quickly will let you benefit from a performance increase in your application and from lower camera costs. Therefore, a fast change makes sense. On the other hand, there is no immediate rush if you are using CCD-based cameras. They will be available for many years to come. We recommend taking the time to run the calculations on your application, to decide which option would be more advantageous.

What do I have to consider when switching?

Relatively little. You should not have any trouble finding a camera with a suitable CMOS sensor. For an easy switch, choose a CMOS sensor with the same optical format as your current CCD cameras, and you all only have to perform minimal adjustments to your system design. Things are also kept simple if you stay with your standard interface, Gigabit Ethernet. Basler offers all new CMOS sensors within the 29 mm x 29 mm housing of its ace models which allows for easy replacement of nearly all existing camera designs. It also brings along improved performance in replacement scenarios of analog FireWire cameras, where space limits are a crucial concern.

What is important when integrating the latest CMOS-based cameras?

Integrating a CMOS camera to replace CCD sensors is simpler than expected, especially when you choose standard-compliant hardware and software. Because camera manufacturers take care of the entire sensor integration including image quality optimization, all you need to do when choosing the right CMOS camera is to:

  • Determine the correct resolution of the camera: The required resolution depends on the details you need to make visible in your images.
  • Define the required camera interface: The choice of an interface depends on the required cable length, bandwidth, necessary frame rates and real-time capabilities and PC hardware availability. Our Interface Advisor helps you find the best interface for your application.
  • Choose lens and lighting: Changing the sensor format also involves changing the lens. Our Lens Selector makes finding a new lens easy. Lighting must only be adjusted if the sensitivity of the new sensor is different from the previous one.
  • Integration effort for software and camera control: Cameras complying with common standards such as GenICam, for example, or interface standards like USB3 Vision or GigE Vision, offer uncomplicated integration.
Which CMOS successors does Baslers portfolio offer today?

Basler has anticipated the trend towards CMOS sensor technology in industrial cameras early on and offers a broad product portfolio of CMOS cameras with sensors from various manufacturers. Just recently, it equipped two ace GigE and two ace USB 3.0 models with Sonys IMX174 CMOS sensor. With a resolution of 2.3 MP and frame rates of 50 fps (GigE) and 155 fps (USB 3.0), respectively, this powerful sensor is a recommended choice for demanding applications in the fields of traffic, microscopy and medicine.

What is Embedded Vision? – New Vision Campus Video

http://mvrpl.com

If you think industrial cameras are roughly the size of a carton of milk and their computers are big enough to work as chairs, you're a little behind the times. Machine Vision system components were as big a few years ago, but not any more.

Over time PCs have shrunk, in some cases down to no more than a compact, application-specific processing board. The cameras have gotten smaller, too and are now often available without a housing – allowing them to be integrated into a larger system. 



These two trends toward miniaturization of PCs and the camera make it possible for vision systems to be produced affordably and for highly specific applications. A system of this kind is referred to as an embedded vision system.

Want to find out more about this topic? Then watch the new video in the Vision Campus on What is Embedded Vision? It contains more in-depth information, such as how an embedded vision system is constructed, its benefits and where these systems are used.

The Vision Campus contains detailed articles and videos on Machine Vision and on Vision technology in general. We explain for example why it's important to choose the right lighting for your image processing task and why CMOS sensors are the technology of the future – presented in text and video form. See for yourself!

Y-Cable for Use of All I/Os on Basler ace Cameras with the Latest CMOS Sensors without Interferences

http://mvrpl.com

The ace GigE cameras with Sony’s IMX sensors and the PYTHON sensors from ON Semiconductor and all ace USB 3.0 cameras have two I/O types: direct coupled GPIO and opto-coupled I/O. Our new Y-cable allows you to use both types simultaneously without the opto-coupled I/Os interfering with the GPIO signals due to crosstalk. There are two separate wires to split both I/O types. The two wires on the Y-cable have different colors to distinguish between them (GPIO = yellow, opto-I/O = blue).The cables are 10 meters long with open ends so that they can be shortened individually to fit your application.

For all ace GigE cameras (with/without GPIO) the GPIO cable also supplies power to the camera. This design allows a separate wiring of trigger signal and power.

Tips for cleaning dust from a sensor

http://mvrpl.com

When changing lenses on machine vision cameras, some dust might get into the camera and land on the sensor’s cover glass. If this occurs, this dust will affect image quality. Read More to know how to clean dust from the sensor’s cover glass or other protective glass.
Important: “glassless” imagers, where the cover glass has been removed for UV sensitivity or other reasons SHOULD NOT be cleaned using this process.

1. What you need:

  • Flat LED light source whose light power is adjustable.
  • Lens whose aperture is adjustable; from completely closed to wide open, for example, COSMICAR.
  • C25010 (1inch, 50mm F1.8).
  • Cleaning fluid (see Note 1 below).
  • ESD-safe swab (see Note 2 below).
  • Lint-free gloves.
  • Moisture-free compressed air (optional).
Note 1: For cleaning fluid, isopropyl alcohol is a good starting point however, it may not be sufficient to remove all dust. A mixture of 70% isopropyl alcohol with 30% ether is recommended. Please read and follow safety precautions when mixing these chemicals.
Note 2: To avoid leaving any fibers behind, standard cotton swabs should not be used. Instead, the use of specialized ESD-safe swabs is strongly recommended.

2. How to clean up

The cleaning process (Steps 4-6 below) should be performed in a cleanroom or under a dust-free hood if a cleanroom is not available. Proper clothing should be worn in cleanrooms. At a minimum, lint-free gloves should always be worn during cleaning to avoid introducing additional contaminants.
1) Set up camera with lens and PC to monitor images from the camera.

2) Adjust the lens aperture to almost closed (small aperture); adjust the intensity of the flat LED to produce an image that is not saturated.

3) Check images from the camera to see whether or not some dust exists.
Some tips when trying to identify dust on the cover glass/filter glass are as follows:
  • Is the dust on the sensor glass or light source? Try moving the camera physically. If the dust moves when the camera is moving, the dust is on the light source.
  • Is the dust on the sensor glass or monitor? Try moving the image window on PC. If the dust does *not* follow the image window, the dust is on the monitor.
  • Is the dust on the sensor glass or lens? Try rotating the lens (loosening the lens). If the dust follows the lens rotation, the dust is on the lens.
Example image of dust:
4) If some dust exists on the cover glass, then,
  • Remove the lens
  • If you have a can of moisture-free compressed air, you can try a short burst to loosen the dust particles. Be sure to let the air run for 1-2 seconds away from the camera first, to clean out any contaminants in the nozzle. It is important that the compressed air be completely dry, otherwise it will introduce additional contamination. If you are not sure whether the compressed air being used is truly moisture-free, you should skip this step.
  • Put a little bit of cleaner fluid on the swab.
  • Touch the swab to top-left or top-right corner of the sensor’s cover glass, then wipe straight across to the other edge of the sensor (e.g., from left edge to right edge).
  • Lift the swab and return to a point just below where the first pass started and repeat the process.
  • Continue until the entire cover glass has been cleaned in the same direction.
  • Do not wipe back-and-forth across the sensor as this may unnecessarily drag dust particles across the surface.
5) Attach the lens and go back to Step 3. If some dust still exists, execute Step 4 again with a brand-new swab.
Note: Re-use of swab is not recommended due to the risk of reintroducing foreign object debris (FODs).
The cover glass could become dirtier.

6) Repeat Steps 3 – 5 until the cover glass becomes clean

Wide-Angle “FUJINON HF6XA-5M” Machine Vision Lens

  • Fujifilm produces the world's smallest wide-angle 6mm lens for 2/3”, 5-megapixel image sensors
  • Achieving high even resolution performance from the center of the image to the edges with “4D High Resolution”
  • Newly Development
FUJIFILM Corporation (President: Kenji Sukeno) has announced the development of the FUJINON HF6XA-5M wide-angle Lens (hereinafter “HF6XA”). This new product, which has an external diameter of 39 mm and a focal length of 6 mm, is the world's smallest* Machine Vision lens which is used for industrial processes such as product inspection and measurement on production lines. HF6XA is a new lens which is designed for compatibility with 2/3” sensors with a pixel pitch of 3.45µm (five megapixels).

HF6XA is a FUJINON Machine Vision lens designed for compatibility with 2/3” sensors, which has coverage of approximately twice the current product, the FUJINON HF8XA, which offers the widest coverage range. In the frequently used environments of customers, the lens is compatible with the ultra-high resolution of 3.45µm pixel pitch (equivalent to five megapixels when using a 2/3” sensor) under a large portion of the screen. Furthermore, for a wide range of installations and shooting conditions, the lens boasts “4D High Resolution”*4 performance, mitigating resolution degradation that typically occurs when changing a shooting distance or aperture value and maintaining a high level of even image sharpness across the entire image area at the ultra-high resolution of 4.4µm pixel pitch (equivalent to three megapixels when using a 2/3” sensor). Despite being a wide-angle 6mm lens, the lens achieves the world's smallest external diameter of just 39 mm. The lens is ideal for attachment inside compact inspection devices with restricted internal space when wide coverage and consistency is required for reading product codes and serial numbers or for inspecting product shape and appearance.

Fujifilm will be exhibiting the HF6XA at VISION 2016, one of the world's largest Machine Vision-related tradeshows, which will be held in Stuttgart, Germany from November 8 through November 10.

In December 2015, Fujifilm released the HF-XA series of five lenses for use with Machine Vision cameras. HF-XA series achieves both high resolution through 4D High Resolution technology and a compact design with an external diameter of 29.5 mm. Users have also praised the camera for features which include a lens barrel with three holes for fixing the iris and three holes for fixing the focus, providing for convenient shooting as the optimum holes can be selected to match the installation conditions. Fujifilm developed the HF6XA in order to respond to the need for a wide-angle lens with even wider coverage that further improves upon the characteristics of the HF-XA series. With the addition of the HF6XA, Fujifilm's portfolio of lenses for Machine Vision cameras now totals six series with a total of 36 models, which can match a wide range of diverse customer needs.

How High-Speed Cameras Can Be Used to Study Human Motion Sequences

http://mvrpl.com

Motion analyses are most commonly used for sports motor skills. The primary task here is to study, train and optimize motion sequences. This applies to both individual and team sports as well as sports that involve the use of equipment or animals.

The applications are multifaceted. Wit the help of slow motion studies swimmers seek to optimize their butterfly stroke after the turn, horse and rider train to achieve a harmonious riding style and athletes improve their long jump. 

Motion analysis is also used in the development and testing of sports equipment and gear. The high-speed video to the right shows a golf stroke that was captured using the MotionBLITZ EoSens® mini1 high-speed camera. This high-speed recording aimed to optimally adapt the club to the player’s movements.

The club head can reach speeds of up to 200 km/h. To capture all the details, a sufficiently high frame rate must be used. This recording was taken at a frame rate of 2,009 frames per second and a resolution of 528 x 518 pixels. A case study explains how swing analysis can be put to good use when equipping golfers.

Motion analysis is also often used in medicine, particularly in the field of rehabilitation: Doctors and other medical professionals seek to visualize motion or gait disorders in order to develop targeted therapies. High-speed imaging helps them to develop individual training plans, to adjust and optimize aids such as insoles, orthotics and prosthetics and to assess the chances of successful orthopedic surgery.

Finding the Right Camera for Every Motion Analysis

At the heart of every motion laboratory is the high-speed camera. Often, multiple synchronously running cameras are used for three-dimensional analyses. To achieve the best results, there are some important points to be considered when selecting the camera. The decisive parameters are the frame rates, resolution and recording times that will be required. Other important criteria include the handling and ease of integration of the high-speed camera.

High Frame Rates

The required frame rate is determined based on the requirements of the motion to be analyzed. A gait analysis, for example, requires a lower frame rate than the analysis of the forehand stop in tennis. Motions in competitive sports are often especially fast. To analyze these processes in sufficient detail, the high-speed camera used must have a high frame rate of at least 500 pictures per second. 

The high-speed recording on the left shows the golf club head at impact. This is the critical moment for the analysis, the moment of the impact. It determines the ball’s takeoff velocity, direction of flight and spin. Here, the small image region meant the resolution could be reduced to 832 x 172 pixels. This allowed the MotionBLITZ EoSens®mini1 to reach a frame rate of 4,188 frames per second.

High-Precision Resolution

Resolution is crucial for the sharpness and the detail level of the recordings. This also depends on the specific requirements: For example, to achieve the same level of detailed sharpness, high-speed recordings of lower limb prostheses require a higher resolution than the images of prosthetic feet. 

The slow-motion sequence to the left was recording using the MotionBLITZ EoSens® Cube6. With a pixel resolution of 1,280 x 1,024 the camera delivered 150 frames per second. The video shows a jetski driver performing a bootleg turn. 

The MotionBLITZ EoSens® mini2 offers a resolution of 1,696 x 1,710 pixels; thus, it delivers extremely sharp images at maximum recording speeds of 523 frames per second. Here, the resolution is proportional to the recording speed.

The Right Recording Time

Since the entire motion process must be stored in the camera’s memory, the recording time is another important criterion when selecting the camera. For example, there are different requirements depending on whether you are recording a complete obstacle course run or only the start of it. In general, the camera should follow the defined test protocol – and not vice versa; the camera should not affect or even define the test sequence. 

Memory cameras offer recording times between 2 seconds and a maximum of 15 seconds. The MotionBLITZ® Cube records at full resolution and speed for up to 13 seconds. For a longer recording time, the frame rate and/or resolution can be reduced. For example, for a recording time of 30 seconds, a resolution of 100 x 800 pixels and a frame rate of 300 frames per second can be set. If longer recording times are required, Mikrotron offers long-time recording systems that can record from several minutes up to a few hours. 

This underwater video shows a diver during immersion. Having the right position is crucial: The diver should dive perpendicularly into the water and no longer be in the final stages of a turn. The video was taken with the MotionBLITZ EoSens® Cube6 at a frame rate of 718 frames per second and a resolution of 1,280 x 720 pixels. These settings allowed a recording time of 3.25 seconds. The camera was operated by hand.

Compact Handling

When selecting the right camera, the performance characteristics are of foremost importance. However, the design may also be an important criterion: overly large high-speed cameras can be more difficult to handle and reduce the usability, especially when space for the camera is limited. At the same time, the size of the camera is a characteristic that often only becomes apparent in the field: For example, if you want to record each part of a pole vault sequence on a training field, you need a fast and flexible high-speed camera. Confusing cables or unwieldy devices make it difficult to concentrate on the task at hand and should therefore be avoided. Mikrotron offers compact systems with ideal sizes of 65 x 65 x 65 mm to 200 x 200 x 350 mm. 

The high-speed video on the left shows a high jumper at the critical point of take-off. During the jump, the jumper must convert the horizontal velocity into vertical velocity and initiate the turn to cross the bar. The image sequence was created within 1 ¾ seconds and consists of a total of 1,764 images. The images were taken with the MotionBLITZ® Cube1 at a resolution of 640 x 512 pixels. Thanks to the compact size, flexible use in the field is also possible.

The high-speed Cube and eosens TS3 cameras by MIKROTRON can also operate completely selfsufficiently, without an external power supply, and run on battery power for up to one hour. In addition, the cameras have an internal SSD memory, where all data can be stored for final analysis. For example, the eosens TS3 can record without being connected to a computer for up to 13 seconds at full recording resolution and speed.

The software included in the delivery allows for easy use of the cameras. It will win you over with its well-executed and intuitive workflows, easily recognizable features and easy-to-use elements. It also offers the option to synchronize multiple cameras so that they can record at the same time. The software can be easily installed and operated on all computers – special hardware is not required.

A Range of Interfaces

MIKROTRON high-speed cameras are supplied with a C- or F-Mount lens connection. The C-Mount can be adapted to the greatest range of systems, including special optical systems such as endoscopes or telecentric lenses. F-Mount lenses also offer a particularly good imaging quality at focal lengths of over 50 mm. Open interfaces on the cameras allow users to select their own optical systems. For example, camera lenses, zoom lenses and microscopes can be connected without problems. Moreover, all MIKROTRON cameras are equipped with a trigger input. This means you do not have to stand next to the camera to start the recording – it can be easily started with a trigger. In addition, the models have interfaces that facilitate a parallel recording of analogue and digital signals.

An Extensive Portfolio

When choosing the right camera for the high-speed imaging of movements, several parameters play a crucial role. This includes the frame rate, resolution, and recording time, but also the handling, us ility and flexibility of the camera. It is equally important to consider the specific demands of each task. MIKROTRON’s product portfolio offers different options depending on the specific parameters and thus offers a suitable solution for each task.
