Research on 2D Laser Radar Indoor Planar Data Preprocessing Methods
s:When 2D LiDAR is used to scan and measure the building room,the LiDAR point cloud will be interfered by noise,outlier jump points and missing data,which will affect the processing speed of the point cloud data.In order to improve the processing speed of 2D LiDAR point cloud data and the accuracy of building room planar drawing,the algorithms such as difference filtering method,least squares method and dynamic threshold feature extraction method are used to realize the preprocessing of 2D LiDAR point cloud data.The point cloud data preprocessing method is verified through experiments,and the results show that 2D LiDAR can quickly obtain the dimensional information of doors,windows,beams,and columns,and can significantly improve the measurement accuracy of architectural space and the efficiency of planar drawing.
