摘要
激光测量中的多视点云精确对齐,采用旋转台旋转对齐方法。即先将定制标定表安置在旋转台上,利用激光扫描仪进行测量,通过计算获取旋转台中心轴线坐标参数。再以旋转台中心轴线坐标和旋转台旋转角度参数,粗略对齐不同视角下的数据点云。最后用邻近点迭代(ICP)算法实现精确对齐。
Aiming at the align problem of points-cloud measured by laser under different viewpoints, a circumrotated align method based on rotating platform is adopted. At first, the customized demarcate chart is installed on rotating platform, and the measure is carried through laser digitizer, the center axes parameter of rotated platform is obtained by computer. Then, the points-cloud under different viewpoints is aligned in the rough with the center axes parameter and rotating angle parameter of rotated platform. Finally, the accurate align is accomplished by Iterative Closest Points （ICP）.
