摘　　要：EDM距离交会是利用EDM测距精度可靠、实测方便、效率高的特点而确定点位的一种方法。由于交会的点位精度可靠、方法简练,较多的应用于工程实际,本文利用误差理论的基本知识较系统地对交会点位的精度及任意方向的偏差进行了分析,为快速预测点位精度及偏差提供了借鉴。EDM intersection is a method based on EDM＇ s reliable measuring accuracy, easy use and effective performance, which has been widely used in engineering project. This paper, in view of error theory principle, systematically analyzes the accuracy of intersection point and the error occurred in any direction when used it and gives some useful experiences.
