Three-dimensional data unevenness binarization display method and three-dimensional data unevenness binarization display program

摘要

PROBLEM TO BE SOLVED: To grasp the shape of an entire object to be measured three-dimensionally and to obtain binarized irregularities on the surface of the object. SOLUTION: Image data obtained by photographing a measurement object 20 from various angles, or position data acquired by scanning a measurement object 20 from various angles including a plurality of reference objects 22 by a laser scanner is obtained by a computer 30. The point group data of the measurement target 20 is acquired from a plurality of image data or a plurality of position data, and based on the point group data, polygon data including the surface of the measurement target is created and the created polygon data. The color of the copied polygon data is changed to a color different from that of the copy source polygon data, the surface of the copied polygon data is smoothed, and the copied polygon data after the smoothing process and the copy source Overlay with polygon data.
