航空摄影单像空间后方交会在智慧矿山中的精度控制

Aerial photography single space resection in Digital Mine Precision Control

航空摄影测量单像空间后方交会是摄影测量的一个根本性问题。单像空间后方交会主要是用来求解外方位元素,而其精度直接影响到了后续的摄影测量工作和数据处理,给生产带来不便。本文在以实际智慧矿山建设的背景环境下,从像控点的数量出发进行比较分析。结果表明:像控点的数目对航空摄影单像空间后方交会的精度有影响,并且增加像控点的数目,可以提高单像空间后方交会的精度。

Aerial photogrammetry single image space resection is a fundamental problem of photogrammetry.Single image space resection is mainly used to solve the exterior orientation elements,which directly affects the accuracy of the photogrammetry and the subsequent data processing to produce the inconvenience.Based on the actual digital mine construction background,Comparative analysis from the starting point as the number of control.The results show that control the number of points of aerial photography single image space resection accuracy influence,and increased as number of control points can improve the single image space resection accuracy.
