| 摘 要： | 本文对倾斜航空摄影的关键技术进行了研究，将倾斜航空摄影技术引入矿山地质环境调查领域，通过倾斜航空摄影设备获取了目标区域多视角航空影像，基于立体像对制作了DOM和高精度的DEM，并利用像片控制点成果和航空摄影系统POS数据，制作出高精度的实景三维地形模型，基于Skyline平台进行二次开发，结合矿山历史遥感监测及地质灾害隐患数据，完成了数据库的建立以及矿山地质环境管理系统的建设。主要包括实景三维环境下的矿点及地质灾害隐患点查询、修改、统计、分析等功能。结果分析得出，采用倾斜航空摄影技术生产传统4D产品和实景三维模型，具有周期短、信息多元化的特点，极大地减少了外业核查劳动强度，能更好地满足矿山地质环境监测管理的需求。

| Abstract: | We explore the key techniques of oblique aerial photography in this paper, and take the lead in introducing oblique aerial photography technology into the field of mine geological environment investigation. We acquire multi-angle aerial images of the target area through oblique aerial photography equipment, and produce DOM and high-precision DEM based on stereopair, and use the results of the image control points and the POS data of the aerial photography system to produce a high-precision real three-dimensional terrain model. We carry out secondary development based on the Skyline platform, and the establishment of the database and the mine geological environment management system is complete combine with data of historical remote sensing monitoring of mines and the hidden geological hazard, which mainly includes the functions of query, modification, statistics, and analysis of mine points and hidden danger points of geological disasters in the real three-dimensional environment. The results show that the use of oblique aerial photography technology to produce traditional 4D products and real 3D models has the characteristics of short cycle and diversified information, which greatly reduces the labor intensity of field inspection and can better meet the needs of geological environment monitoring and management in mines. |
