| 摘 要： | 随着计算机技术的飞速发展和近景摄影测量应用范围的日益拓广，非量测用摄影机作为影像信息的获取手段亦已显出其优越性。在真正建立非量测用摄影机所片与目标物间已知的数学关系中，控制点起着不可缺少的桥梁作用，不讼是控制点的布设是数量都将直接影响到目标物物方坐标的解算精度。

| Abstract: | The crux to use non surveying camera in close range photogrammetry lies in selection of control points. The distribution and number of control points will directly affect the precision of the solutions for object coordinates. An experiment is conducted with a common camera to study the influences of distribution of control points in DLT algorithm on the precision of the solution for object coodinates, and the satisfactory results are obtained. |
