航空摄影测量在矿区1:2000地形图测绘中的应用研究

Application of aerial photogrammetry on topographic map of mining area with 1: 2 000 scale

为验证无人机影像应用于矿区地形图测绘的可行性,本文以"冀中能源邯郸矿业集团太行矿业有限公司矿区基础地形图更新"为例实践了一套大比例尺地形图航空摄影测量的方法,并对空三加密及成图精度进行了分析。地形图检查点平面精度均在0.25 m以内,高程精度小于规范中误差的点数为80.1%,满足了矿区生产作业的需求。

In order to verify the feasibility of surveying topographic map with UAV images in mining area, this paper has taken the updates of basic topographic map of mining area of Jizhong Energy Han- dan Mining Group Taihang Mining Co. Ltd. for example and have practiced a set of aerial photogram- metry methods of large -scale topographic map, and have analyzed aerial triangulation and mapping accuracy. The plane precision of checkpoints are all within 0.25 m, and there are 80. 1% elevation points which are less than the standard error. The topographic map has met the needs of production op- erations of mining area.
