Design and implementation of points position cloud calculation based on software-hardware co-design

Abstract

Airborne lidar has a wide range of applications in mapping, exploration and so on. Its data processing uses the ranging data of LiDAR and the position and orientation information to obtain high precision surface models. In order to meet the real-time requirements of airborne LiDAR points position cloud calculation, a software-hardware co-design based method is used to design and implement the SoC of points position cloud calculation. A high-performance hardware accelerator is realized by using the AXI-4-based DMA high-speed transmission and using pipeline optimization and storage optimization methods. The experimental results show that the proposed SoC of points position cloud calculation can meet the real-time processing requirements of the airborne platform.
