Project Description

Safety Imaging provides municipalities with video enforcement of stop sign violations. Robust Device served as their electronics and software engineering resource to develop their multi-camera DVR system. Using COTS multimedia boards (Leopardboards from Leopard Imaging) and our own custom controller PCB, Robust Device designed a system to operate 4 cameras synchronously to track violations. High definition video is stored on removable SD cards and the entire system is battery operated.

We developed a Linux desktop software application to allow the field operators to configure the systems. The GUI allows users to designate on/off recording times and to stream video for aiming and focusing the cameras.

Application-specific auto exposure and auto white balance video processing algorithms were developed which make it possible to resolve license plates and vehicle color over a wide range of lighting conditions.  The Leopardboards run an embedded Linux operating system using RidgeRun’s SDK. Patent applications have been filed for both the system and the auto-exposure and auto white balance algorithms.
