手持式激光扫描仪激光点云数据拼接方法
A Laser Point Cloud Data Splicing Method for Hand-Held Laser Scanners
摘要
现有的手持式激光扫描仪在使用过程中多使用定位标志点,会遮盖部分数据。针对此问题,基于单应矩阵和霍夫直线提取提出了一种新的线结构光点云数据拼接方法,可以避免在扫描过程中粘贴标志点。实验结果证明,该方法能准确得到目标三维点云数据,拼接误差小于1 mm。
Abstract
Positioning mark points are often adopted when operating the existing hand-held laser scanners,which may shelter some of the data.To solve this problem,a new method based on the homography matrix and the Hof line extraction method is proposed for data splicing,which can avoid sticking the mark points in the scanning process.The experimental results show that the 3D-point cloud data can be obtained accurately by using this method,and the splicing error is below 1 mm.
