摘    要：本文介绍了用PC-1500A计算机进行地面立体摄影测量解析法成图中,根据图板上补点的平面坐标和高程,通过编程由计算机快速计算并打印输出在立体坐标量测仪上进行安置所需要的数据, 迅速找到补点在立体模型中相应位置的方法。文中推导了有关的公式,列出了有关的BASIC子程序清单。用这种方法确定补点的位置,可以大大提高补点的工作 效率。

Abstract: The author describes in this paper a procedure with which the approximatecorresponding positions in the stereo-model constructed within the stereo-com-parator can be quickly found by inputting the coordinates and the elevationsof the desired etail points on the planimetric plate into the PC-1500A computor,provided that the points are ot located in the dead areas.The relevant formulasare given,and a list of BASIC subroutine is ovided.The efficiency can begreatly enhanced by using the procedure in the analytical errestrial photographicmapping in case some additional detail points are needed for balancing he den-sity of the detail points on the plate.
