ACQUIREMENT AND COMPUTER PROCESSING OF 3-D SURFACE SHAPE DATA

摘要

The laser scanning and CCD image-transmitting measurement method and principle on acquiring 3-D curved surface shape data are discussed. Computer processing technique of 3-D curved surface shape(be called"3-D surface shape" for short) data is analysed. This technique includes these concrete methods and principles such as data smoothing, fitting, reconstructing ,eliminating and so on. The example and result about computer processing of 3-D surface shape data are given.
