长度投影变形对CP III平面网精度影响的计算实验
Computational experiments about the influence of projective defermation on horizontal CPIII central network
摘要
Abstract
In order to investigate projective deformation’ s impact in CPIII plane measurements, This paper has chosen three segments of different lengths measured CPIII plane, as a contrast, another CPIII plane without pro-jective deformation has been simulated. Then , different proportions changes have been added on measured dis-tances in this four planes, this paper analysis the precisions of all the control points in different proportions, and find out the most precisions will be achieved by using the value of K, which calculated from free-network adjust-ment. This conclusion is properly provide a useful reference in CPIII plane data processing.关键词
