| 摘 要： | 本文从理论上推导了工程摄影测量中交向摄影方式各元素影响物点坐标精度的严密公式,并根据理论分析的结果,采用先进的数码相机和量测相机进行了一定的试验,在仔细分析试验结果的基础上,找出了工程摄影测量中交向摄影最佳的交向角、摄影基线、摄影距离和摄影比例尺等参数,对物点坐标总精度的影响规律。实际作业中,要使最佳交向摄影方式获得最理想的点位精度,所总结出的结论是可行的。

| Abstract: | The paper theoretically derives a strict formula which reflects the effects of each factor in the convergent photographic mode of engineering photogrammetry on the accuracy of object coordinate.According to theory analysis,the test was done with digital camera and topographic camera.Based on test result,the influence regularity to the accuracy of object coordinate affected by several parameters,such as the best cross angle of cross photography,photographic base,photographic distance,photographic scale,is fo... |
