近景摄影测量在三维数据采集中的应用
Application of close range photogrammetry technology in 3D data acquisition
摘要
Abstract
Grating projection scanning equipments are often used to detect 3D data of industrial products,such to acquire precise surface size of products. Photographs merging has a large accumulated error in the measurement of large-size surface due to the principle of uncoded point three-point fix. Using close-range photogrammetry method to build three-dimensional measurement of uncoded point group is an effective means to improve accuracy of the three-dimensional measurement. Describes the principles and methods of close-range industrial photogrammetry systematically. A multi-camera station close-range photogrammetry method combined with the grating projection scanning method is introduced to achieve accurate measurement of large-size objects. A case study of surface measurement of motor vehicles shown that, compare with a separate raster scan method, close-range photogrammetry combined with the raster scan method not only improve the scanning efficiency but also increased the accuracy of the scanning of large-size objects substantially.关键词
