摘要：In a machine vision system utilizing computer processing of image data, animaging module incorporates the image sensor as well as pre-processing circuitry, for

example, for performing a background subtraction and/or a gradient calculation. Thepre-processing circuitry may also compress the image information. The host computerreceives the pre-processed image data and performs all other calculations necessary tocomplete the machine vision application, for example, to determine one or more wheelalignment parameters of a subject vehicle. In a disclosed example useful for wheelalignment, the module also includes illumination elements, and the module circuitryprovides associated camera control. The background subtraction, gradient calculationand associated compression require simpler, less expensive circuitry than for typicalimage pre-processing boards. Yet, the pre-processing at the imaging module

substantially reduces the processing burden on the host computer when compared tomachine vision implementations using direct streaming of image data to the hostcomputer.
