IMAGE PROCESSING DEVICE, SINGULAR SPOT DETECTION METHOD, AND RECORDING MEDIUM UPON WHICH SINGULAR SPOT DETECTION PROGRAM IS RECORDED

This image processing device comprises a distance image capture device which captures a distance image based upon three dimensional coordinate values obtained for various points upon object surfaces by a distance sensor; a plane detection device which detects planes from said three dimensional coordinate values upon said object surfaces obtained from said distance image; an edge detection device which detects edges from said distance image; a singular spot decision device which decides whether or not said edges include singular spots, according to whether or not the edges which have been detected by said edge detection device and the planes which have been detected by said plane detection device satisfy predetermined conditions; and a singular spot map storage device which stores said singular spots, based upon the results from said singular spot decision device.
