摘要：

The design and testing of an efficient method for measurement of the location of corners of binary regions in digital images is described. From a single perspective image, the image coordinates of corner points are obtained from moments and intersection points accumulated within specified windows. Corner-point coordinates may then be used in further processing such as inverse photogrammetric solutions to determine 3D position. A video-processing board based on a TMS 320C25 DSP chip has been developed to process the image windows. Together with an 80386-based single-board computer, object corner location is achieved at the standard RS-170 television field rate of 60 Hz.
