摘　　要：本文介绍构建以全数字摄影测量、高分辨率遥感卫星影像、地形图等多数据源为基础,通过立体匹配技术生成大场景三维立体量测平台,为输电线路优化选线提供强大的技术支撑,实现输电线路勘测设计作业流程的创新。This paper discussed 3D measurement system which was using digital photogrammetry, high-resolution remote sensing image and relief map and so on, in order to build up the larger scene 3D stereo environment by the stereo-mate technique. The system provides strong technique support in quickly optimizing the transmission line selection. It also realizes the workflow innovation of surveying and designing in transmission line.
