中文摘要：

对Photogrammetry技术的主要原理进行了解析,并利用该技术从空间多角度对预先设置的20个目标点进行图像采集,获取连续的三维影像信息,通过PM软件进行采矿区目标点重现,获得了各个检测点的三维坐标大小,并对两种焦距下的图像处理结果进行了对比分析,对实际工程应用具有借鉴意义。

英文摘要：

The principle of Photogrammetric method was analyzed,and this method was used to collect images for 20 pre-set targets in different angles of space,with continuous 3D image information obtained.The target point can be reproduced with PM software,with coordinate value of 3D targets obtained.The images obtained by two different focuses were treated and analyzed by comparison,which has some significance for being referred in practical engineering project.
