ABSTRACT:
A system and method for calibration and compensation of a visual sensor system. The visual sensor system includes dark pixels adjacent active pixels on a CCD imaging array, which provide dark current data corresponding to image response data. Concurrently, the temperature of the focal plane of the CCD is measured by one or more temperature sensors disposed on the array. Concurrently, the temperature of a circuit board including a processor is measured by one or more temperature sensors arranged on the circuit board. The image response data, dark current data, and circuit board and focal plane temperatures are used to compensate the image response data.
