三维激光扫描技术中的点云拼接精度问题探讨

摘要

针对误差积累导致点云拼接方法精度较低的问题,提出了结合传统测绘技术建立精确控制网,在绝对坐标系下的点云拼接方法,并通过实验证明了该方法的有效性,对促进三维激光扫描技术的广泛应用具有一定指导意义。%According to the problem of error accumulation leaded to the lower precision of registration point clouds methods, this paper put forward combining with the traditional surveying mapping technology and to establish the precision control network, the point clouds registration method under the absolute coordinate, and through the experiment proved the validity of this method, had a certain guiding significance to promote the popularization and application of TLS technology.
