摘　　要：本文提出一种基于普通数码相机的露采矿山储量快速检测方法,该方法将普通数码相机进行高精度标定,用于矿山宕口摄影,经过影像畸变校正、相对定向、绝对定向、影像匹配与坐标转换,对开采宕口进行三维重建,再根据前期地形数据,计算矿山储量变化。基于该方法开发的露采矿山储量动态检测系统,经过实际应用证明能够显著提高储量检测的效率和精度。In view of the governmental request on mine reserve inspection and the deficiencies of current methods, a method of rapid reserve inspection of opencast mine using ordinary digital camera was proposed in this paper. In this method, an ordinary digital camera calibrated accurately was used to photograph the mine pits firstly. Then the 3D pits were reconstructed after the image distortion correction, relative orientation, absolute orientation, stereo matching and coordinate transformation. Finally, the change of mine reserve was computed by compared with the previous terrain data. A dynamic surveying system of opencast mine reserve was developed based on this method, and its practical application was proved to be able to improve the efficiency and accuracy of the reserve inspection.
