摘要
通过对城市老区和城市新区采集点云数据和纠正点数据,进行精度统计,获得纠正点数量、纠正点布设间距的经验数据,为车载激光建模测量的广泛应用提供参考。
Through collecting point cloud data and correcting point data in old urban area and new urban area,we made the precision statistics,and obtained the number of correcting points and the empirical data of correcting point spacing.This study can lay a solid foundation for the wide application of vehicle-borne laser modeling and measuring.
