摘要
利用严密误差分析方法,对边角后方交会几何图形进行分析,得出最优图形,并根据得出的点位误差等值线圈定边角后方交会图形的"危险区域"。同时根据工程现场实际情况有针对性地提出改进或优化图形的方法。
According to the refined error analysis,the optimum graph can be obtained after analysis the geometric drawing which is linear-angular resection.Then the risk area of the linear-angular resection can be obtained by point to point error isoneph delineation.In addition,a method of graph modification and optimization can be reached according to practical situation in field engineering.
