METHOD AND DEVICE FOR DETECTING RUGGEDNESS OF THREE-DIMENSIONAL DATA

摘要

PROBLEM TO BE SOLVED: To provide a ruggedness detection method and device, which can detect the fine ruggedness area of three-dimensional data showing the surface of an object. SOLUTION: CPU 1 compares a second order partial differentiation value on three-dimensional data showing the surface of the object becoming a reference for detecting the ruggedness area with the second order partial differentiation value on three-dimensional data existing near the value. When respective codes are inverted, three-dimensional data becoming the reference is judged to be included in the ruggedness area. CPU 1 detects the ruggedness areas all over the surface of the object and the detected result is displayed on a picture display part 2.
