摘　　要：本文介绍了基于GPS的近景测量定位方法所需硬件的集成方式及功能,分析了该方法定位的基本原理,并对试验结果进行了分析,验证该方法的可行性及定位精度。利用交向摄影方式,用一台相机,分别在两个摄站点获取同一范围的影像,利用数字罗盘测相机的姿态,GPS测摄站点坐标,利用单片后方交会及像对前方交会解求待定地物点的三维坐标,为不易到达地区目标测量提供技术方法。This paper introduced integration way and function of hardware for locating method of close-range photogrammetry based on GPS, analyzed theory of this method and result of experiment and validated feasibility amt precision of this method. Three-dimen- sional coordinate of unknown point can be computed by method of resection for one image and forward intersection for a pair of image, obtaining image of same range by one camera at two different place using convergent photography, measuring pose of camera by digital compass and surveying coordinate of station where taking pictures by GPS, which would provide technology anti method to measure the region where is difficult to arrive.

关 键 词：近景摄影测量 GPS 交向摄影 后方交会 前方交会
