Sensor Cover Glass Removal: Machine vision camera customization for enhanced accuracy

Standard image sensors found in industrial cameras come ‘of the shelf’ and can have limitations that can stand in the way of optimal performance, accuracy, and application-usefulness. As a result, it is often necessary to customize the sensors to meet specific system requirements.  Addressing certain aspects of sensors is a way how experienced camera manufacturers…

Considerations when using machine vision cameras in traffic applications – ITS

The latest machine vision camera technology can allow for improvements in intelligent traffic system (ITS) performance to minimize detection time in case of accidents, increase the detection rates in cases of violations, and minimize overall costs from police time and traffic jams.  With decreasing budgets, these systems also need to maintain reasonable costs and prove…

CCD versus CMOS in Traffic Applications

For intelligent traffic systems, VGA resolution CCD-based cameras have traditionally been the accepted technology, but with the quality of CMOS image sensors continuously improving, CMOS-based cameras are now a viable option for demanding license plate recognition applications.  The latest system requirements are for higher resolution (HDTV) and frame rates of 30 to 60 frames per…
