摘要
详细介绍了倾斜摄影技术在露天矿区三维场景重建中涉及的关键技术。首先,依据多旋翼无人机特点设计航线采集露天矿区多视倾斜影像数据;然后,对采集的多视影像数据进行数据处理流程以及关键技术的详细论述,并构建露天矿区实景三维模型;最后,利用外业检查点对生成的实景三维模型进行精度分析对比。实验结果表明:通过倾斜摄影方式采集多视影像数据构建露天矿区实景三维模型,平面、高程精度均满足大比例尺测图规范要求,成果满足废弃矿山生态修复工程需求。
In order to help in the design stage of ecological restoration project, this paper introduces in detail the key technologies involved in the three-dimensional scene reconstruction of open-pit mining area. Firstly, according to the characteristics of multi-rotor UAV, the route is designed to collect multi view tilt image data in open-pit mining area;Then, the data processing flow and key technologies of the collected multi view image data are discussed in detail, and the real three-dimensional model of the open-pit mining area is constructed;Finally, the accuracy of the generated real scene 3 D model is analyzed and compared by using field checkpoints. The experimental results show that by collecting multi view image data by tilt photography to construct the real three-dimensional model of open-pit mining area, the planimetric and vertical accuracy meet the requirements of large-scale mapping specification, and the results meet the requirements of ecological restoration engineering of abandoned mines.
