三维激光扫描点云配准算法与精度研究

3D Laser Scanning Point Cloud Registration Algorithm and Its Accuracy Research

在探讨三维激光扫描仪配准方式的基础上,提出基于多点拟合圆心的算法,根据圆心坐标加权求取靶标点云中心,并对其进行误差评定和点云拼接。实验表明,该算法不仅避免检测出无效圆和减小伪圆出现的概率,还提高了效率。

This paper discussed the registration mode of 3D laser scanner, and put forward multi-point fitting circle algorithm. According to the target center coordinates, this algorithm weighted obtained the target center of point cloud, evaluated the error, and jointed point cloud. The experimental results show that the algorithm not only avoids the detection of invalid and decreases the probability of pseudo circle appeared, but also improves the efficiency of the algorithm.
