后方距离交会与角度交会对观测成果的影响研究

A New Method to Obtain the Intersection Point

结合工程实例介绍了控制点间不能通视时快速求解交会点进行施工放样的方法,并通过对后方角度交会和距离交会解算!角精度的分析研究,提出根据后方交会的图形结构和仪器的测角测距精度来选择交会方法,在现场很快获取较高精度的交会点坐标来进行施工放样的方法。

In some cases, the control points can not be introduced for rapid visibility at the intersection point with me the construction molding method and additional control points should be used. In this paper, it is proposed that the intersection points of rear edges and corners are calculated to deduce the desired intersection points. High precision coordinates can be obtained.
