An industrial camera for color image processing with mixed lighting conditions

摘要

Industrial camera is an important electric device in the machine vision, which serves as an interface between the computers and the real world. There is an increasing demand on the usage of high-speed, miniaturization, portable, low-power, and smart industrial camera. In this paper, we novelly design and develop such a kind of camera for capturing and processing color images from the real world industrial environment with mixed lighting conditions. Besides, a color image processing flow has been embedded in the camera to gain high quality images. For the seek of the robustness of the proposed camera to lighting variations, we improve the algorithm of automatic white balance (AWB). The improved algorithm achieves a sound white balance processing result on real world images. Finally, we realize all the processing flows and algorithms in the embedded system and apply it to practical applications.
