摘要
针对国产Li DAR点云精度相对较差,平面精度的难以评价,圆形地标面积较大、携带不便、成本高昂且推广困难,十字形地标在尺寸不是足够大的情况下,实际中心与点云拟合中心重合性不好、精度较差的现状,从国产机载Li DAR的平面精度检校与实际应用出发,提出一种基于角锥形状地标的机载Li DAR平面精度检查方法,该方法综合利用飞行向与扫描向的点云,所使用的地标尺寸相对较小,携带方便且便于推广,笔者利用该地标进行野外实地飞行试验,最终实验证明,本文提出的方法可以有效的对Li DAR点云的水平精度进行验证,具有一定的实用价值。
In allusion to the Present situation of the points clouds of a domestic airborne Li DAR system in China were in relatively poor accuracy,the plane precision was difficult to evaluate,the promotion of costly circular landmarks was difficult,their area were large and they were not convenient to carry,at the same time,the actual center and the fitting center of cross landmark did not always overlap and the precision was poor if the landmark was not big enough,and for practical use and the Plane precision's calibration of the domestic airborne Li DAR system,thispaper presented a new method to calibrate the plane precision of points clouds which was based on pyramid-shaped landmarks which were convenient to carry and not very large,and did flight test in the field. Finally experiments show that the method of this paperis effective to validate plane precision of points clouds and has considerable practical value.
