本文论述了利用航摄相片编制镶嵌图,结合立体观察,进行管道线路和土地整平范围的初选;采用精密立体测图仪测制1:1000影相地形图,并采用数字测图仪获得地面数字模型(DTM)。以此分别对实测管道线路和整平范围进行了多种对比分析;编制了微型电子计算机辅助设计计算程序,探讨了航测设计的精度及其经济效益。利用普通摄影机对高层建筑进行近景摄影测量,检测了高层建筑楼柱偏差,分析了量测精度和经济效益。
This paper discusses the use of aerial photos mosaic inlay, combined with three-dimensional observation, pipelines and land leveling range of primaries; using precision stereo mapping instrument for mapping 1: 1000 photographic topography, and obtained with a digital mapping instrument Terrestrial Digital Model (DTM). In this way, a variety of comparative analyzes were made on the measured pipelines and the leveling range respectively. A microcomputer-based computer-aided design and calculation program was compiled and the precision and economic benefits of aerial survey and design were discussed. The use of ordinary cameras for high-rise buildings close-range photogrammetric detection of high-rise building deviation, analysis of the measurement accuracy and economic benefits.
