摘要
针对3维激光扫描仪无法直接获得目标物表面点的大地坐标的缺点,将全站仪导线测量中的定向技术应用到3维激光扫描仪中;根据扫描技术特点,设计了定向标识;根据定向标识的扫描数据,设计了标识的识别算法,并应用最速下降法进行求解,实现了3维激光扫描仪的定向。
The orientating technology of the total stations traverse survey is introduced into the 3D Laser Scanner in order to solve the problem that the 3D Laser Scanner can not get the objects＇geodetic coordinates directly. The orientating marker is designed according to the special features of the scanning; the recognizing algorithm of the orientating marker is designed according to the scanning data of the orientating marker;the problem is solved using the steepest descent method, and the orientation of the 3 D Laser Scanner is realized.
