| 摘 要： | 为满足采矿工程数字化监测和信息化管理的需求,研究一种应用近景摄影测量手段动态监测露采矿山储量变化的方法,并设计开发储量动态检测软件系统。利用标定过的普通数码相机采集矿山近景影像,采用光束法处理影像;针对普通数码影像的特点,研究一种基于SURF特征点提取和短核线搜索的一维匹配方法;通过多期影像建立的三维模型分析,实现对矿山的动态监测。工程实例证明该建模方法快速有效,软件系统极大地提高露采矿山的作业效率和精确度。

| Abstract: | In order to meet the demands of digital monitoring and informationalized management ,this paper studies a method using close range photogrammetry to monitor the opencast mine reserves changes .Based on this method ,a reserve detecting software system is designed and developed .A calibrated general digital camera is used to take photos of a mine .Then the photos are processed with bundle method .A one-dimensional matching method based on SURF feature points extraction and short kernel line search is used to adjust to the close range images .The dynamic monitoring of the mine is realized by analyzing the 3D model contributed of multi-images .Engineering examples demonstrate that the modeling method is fast and effective ,and the software system greatly improves the efficiency and accuracy . |
