Global Registration Method for Mobile 3D Laser Scanning Point Clouds
摘要
Abstract
Addressing the issue of closure errors in the overlapping areas of initial and final survey segments during the closure of segmented point cloud data in mobile 3D laser scanning,we analyzed the methods and principle of point cloud data registration.Focusing on the transformation parameters for point cloud stitching,based on the preliminary registration results,considering the integrity and correlation of point cloud data,we put forward a global registration method taking the transformation relationship between survey segments as parameters,enabling the distribution and correction of closure errors across various survey segments.We applied the correction values into the transformation parameters to adjust the point cloud.The point position discrepancies of corrected results and actual verification points were all within 10 cm,significantly improving data quality,which could demonstrate the feasibility of method and its high practical value.关键词
