The end of December often becomes a time of reflection as we consider the happenings of the year and plan for the upcoming year. Over this last year in industrial imaging and machine vision, we have seen CMOS make technology leaps and approaching the quality of CCD image sensors. A new interface, CoaXPress, became a worldwide…
To optimize your high performance machine vision camera; it needs to be matched with the appropriate lens. We specialize in cameras, but from our years of experience can offer some basics on lens selection. The details and example provided are just a simple overview – please contact us with any complex questions.
There are many camera specifications that drive accuracy. How do you avoid paying too much for excellent image quality? Our short presentation (only 20 slides) will provide you with some background information on 3D measurements and the machine vision camera parameters to consider when moving to 3D.
With this blog, we will continue a short series on comparing camera performance. Some of this can be done by comparing manufacturer provided specification sheets. Usually after you have narrowed down your selection, you want to evaluate the cameras for yourself and perform some measurements to allow for a quantified comparison. This can be a…
The number of cameras and the necessary mix of low- and high-end models you need depends on how you will use a machine-vision system. Ann R. Thryft, Contributing Technical Editor – Test & Measurement World, 10/1/2011 12:00:00 AM Joost van Kuijk CEO/CMO Multiple-camera vision systems can contain anywhere from three cameras for simple applications, such…
The Vision Trade Fair 2011 held in Stuttgart November 8th to 10th was the most successful to date, with 323 exhibitors breaking the 300 mark for the first time as well as setting a new visitor record of 6,752 highly qualified visitors. This is great news about the growth of the machine vision market!
Why is it that cameras for consumer electronic products, e.g. smart phones have more than 5 megapixel tiny cameras that cost next to nothing, are not used for machine vision? The larger pixel image sensors (greater than 5.5 um) can allow for the best accuracy (i.e. Full Well and Read Noise), but they also result in the…
The Optical Transfer Function (OTF) is an important specification of lens performance. The OTF describes both the amplitude and the phase of a signal. In most cases the former, most times indicated as is Modulation Transfer Function (MTF), suffices. Modulation, as it is a measure of the modulation depth (contrast) of an optical signal. The MTF is for that…
CMOS sensor based defense cameras are gaining ground, but for long-term, reliable, high image quality applications, CCDs will continue to be the preferred option for a while. On February 8th, we discussed the CCD vs. CMOS sensors in machine vision cameras. We discussed that CMOS image sensors have shown significant improvements in quality and are quickly approaching that…
For certain imaging applications, a full color image is required for accuracy, particularly with outdoor applications, such as traffic systems (license plate recognition), surveillance, and situational awareness. Adimec’s color cameras can include in-camera color processing which we developed ourselves to be optimized for automated adjustment to ever-changing outdoor conditions. Color processing is optimized to bring human…
