The problem that ballistic coordinates of assembly firing were measured automatically was resolved in a cumulate holes image by the technology of image processing. Based on analyzing the separation detection conditions of imperfect superposition holes and the measurability of ballistic coordinates, the method of automatic measurement was presented on the basis of distance conversion, which is a successful application of distance conversion and watershed. The experimental result indicates that the method is feasible, and the precision of detection is higher than that of artificial detection.
