摘　　要：依据平面靶标进行点云配准时,直接在软件中获取的靶标中心点坐标的精度通常会受到靶标范围内的点云质量的影响,使得配准结果无法满足精密工程测量的要求。本文提出了一种基于RANSAC平面提取靶标最佳拟合平面,然后自动计算靶标中心。试验数据处理结果表明,本文方法可以有效提高平面靶标中心坐标的计算精度。When planar target is used for point cloud registration,the coordinate accuracy of the target center directly obtained in software is usually affected by the quality of the point cloud within target range,which makes the registration results unable to meet the requirements of precision engineering survey.This paper proposes a method based on RANSAC plane to extract the best fit plane of the target,and then automatically calculate the target center.The processing results of experimental data show that the method can effectively improve the coordinate accuracy of the planar target center.
