摘要
利用三维激光扫描仪进行建筑物立面测量时,考虑到测角、测距精度和入射角对点位精度的影响,并通过不同距离、不同角度对扫描间隔影响的试验,得出在满足建筑物测图精度情况下的最佳扫描入射角及扫描距离。
Building facade measurement using 3D laser scanner, the need to consider the angle measuring precision and incident angle on the impact point accuracy, through the effects of different distances and different angles on the test, the optimal scanning incidence angle and scanning distance are obtained in the case of the accuracy of the mapping.
