3D laser imaging method based on low cost 2D laser radar

In this paper, we propose a three-dimensional (3D) laser imaging method. The working principle of laser radar is introduced, and three scanning strategies are proposes based on low-cost two-dimensional (2D) laser radar. Three dimensional point cloud images under different strategies are simulated and analyzed. Combined with the advantages of the three strategies, a 3D laser radar scheme with pitch and rotation function is designed, and the coordinate transformation of 3D laser radar data point cloud display is established. Three-dimensional imaging experiments on real environment scenes are carried out. The experimental results show that the designed 3D laser radar can get 3D point cloud data in real time. It provides support for low cost 3D laser radar to realize 3D reconstruction and image fusion.
