摘要
全球地理信息资源建设与维护更新项目(简称“全球测图”)中,数字表面模型数据(DSM)作为其主要产品之一,它的质量好坏直接影响着后续DOM、DEM生产的工作量和成果质量,而DSM成果质量控制的难点集中存在于对影像弱纹理区域的编辑处理上。本文通过对该项目DSM匹配所使用的两款主要软件CIPS和INPHO间针对沙漠、森林、冰雪和阴影4类常见弱纹理区域的匹配成果进行对比分析,以研究寻求在4类常见弱纹理区域的对应最优处理方案,为后期生产提供参考选择依据。
In the project of global geographic information resources construction and maintenance and renewal(referred to as"global mapping"),digital terrain model(DSM)is one of its main products,and its quality of production directly affects the workload and quality of the subsequent DOM and DEM production.The difficulty of quality control of DSM results lies in the production and processing of image weak texture areas.This paper compares and analyses the matching results of the two main software CIPS and INPHO produced by DSM for four kinds of common weak texture regions:desert,forest,ice and snow,and shadow,in order to find the optimal processing scheme for four kin.
