Enhancing existing ALPR systems using smear reduction in the camera

Posted by Gretchen Alper on Tue, May 21, 2013

Image sensors designed for machine vision applications are proving beneficial in traffic systems, such as automatic license plate recognition systems, because of their exceptional image quality and reliability in extended temperature ranges.  Except, these image sensors are optimized for use under controlled lighting conditions and have challenges in outdoor lighting conditions especially extreme situations such as direct sunlight.  With certain functionality implementations, experienced camera designers can work around these limitations.

How to avoid life cycle costs with COTS

Posted by Gretchen Alper on Wed, Apr 3, 2013

Commercial Off-the-Shelf (COTS) products are appealing solutions for global security applications in order to have lower product costs, a shorter time to market and use of the latest technologies, but life cycle costs must also be considered.

Evaluating Machine Vision Cameras versus Comparing Camera Specification Documents

Posted by Gretchen Alper on Wed, Jan 30, 2013

Many of our customers ask us how they should evaluate cameras in order to find the best solution for their application. There are several reasons why we feel the Photon Transfer Curve (PTC) is useful, especially if you are trying to get the most out of your imaging system such as when detecting small differences between images or using the pixel information as data for measurements. We have shared some detailed information on how to measure the Photon Transfer Curve for CCD or CMOS machine vision cameras because we feel it is an important part of camera evaluation and selection.

5 Steps to Prepare for a Machine Vision Camera Evaluation

Posted by Gretchen Alper on Wed, Jan 16, 2013

It is hard to do a good comparison of machine vision cameras based on the paper specifications.  For instance some give dynamic range while other provide sensitivity.  These two are related but not the same.  Even cameras using the same image sensor do not perform the same.  Seeing and testing the cameras for yourself is most likely required for the right decision.

Real-time Buffered Image Pipeline in Machine Vision Cameras

Posted by Gretchen Alper on Wed, Sep 26, 2012

Traditionally machine vision cameras are designed that the data rate of the image sensor should match with the frame grabber or PC. But common image data rates will soon exceed 10Gbit/s and move up towards 30Gbit/s over the next years.  This means that high performance interface solutions are needed in order to access the full image acquisition potential of these CMOS sensors.
