Paper Abstract

A new high performance CCD camera family is presented. The camera incorporates a micro-controller/PLD combination to provide users with computer control of image acquisition, image processing and analysis. User control of image acquisition includes adjustable gain and offset, data rate and timing.Image processing and analysis algorithms are implemented within PLDs and regulated via the microcontroller. A variety of image processing algorithms are discussed including gray scale thresholding, RLE, edge detection and gauging. Parameters that govern the nature of the image processing algorithm can be computer controlled and randomly accessed. The camera transmits a combination of high speed digital video for frame grabber acquisition and low speed serial analysis and status information to a PC serial prot. Pixel rates at up to 20Mbyte/sec/channel for up to 8 channels combine for data throughputs of up to 160Mbytes/sec/camera. Camera configurations include single and multi-tap, linescan, TDI and area array formats. Up to 15 cameras can be easily integrated together to form a single network through the use of a programmable communication HUB unit. An even larger number of cameras can be linked together by combining several networks into a web. Applications for the programmable camera/HUB technology include web and parts inspection, template matching and gauging.
