摘要
本文系统地介绍了所建立的一个数字近景摄影测量系统PV—1的检校方法,并得出了该系统的点定位精度。初步实验表明。运用直接线性变换法进行点定位精度评定,物方坐标的中误差为:M_x=0.247mm,M_y=0.158mm,M_z=0.272mm,象方坐标的中误差为0.2像元,相对精度为1/6000。
This paper describes the methods of calibration for digital close range photogrammetry system PV-1, and the accuracy of point positioning in PV-1 is given. The primary test results show that, by use DLT, the RMSE of object space coordinates Mx=0.247mm, M_y=0.158mm, M_z=0.272mm. in the image plane, the achieved accuracy amounts to 0.2pixels, the relative accuracy is about 1/6000.
