3D laser scanner design and data processing

Abstract

Based on 2D laser radar and pan-tilt device, a 3D laser scanner is designed as a data acquisition device. At the same time, the scanning control and data processing system is designed on the host computer. The scanning control system realizes the control of the scanning range and the scanning precision. The data processing system converts the coordinates into the global coordinate system through the mapping relationship of the collected data, and converts the data into a standard point cloud format file for storage. In order to further improve the accuracy of the data, after designing the filter to eliminate the outliers, a three-dimensional model is constructed to realize discrete point cloud data visualization. The results show that the system can reconstruct the three-dimensional space better.
