Abstract

Abstract:

Due to the manufacturing process limitation, existing 3D non-scanning lidar APD array was not highly integrated. In order to improve the spatial resolution of 3D non-scanning lidar and to meet the requirements of high-resolution spatial sampling, a method for acquiring super-space resolution information of 3D lidar and 2D detector was proposed in the current study. The method used a high-resolution common illumination source 2D detector to assist the 3D lidar by combining the laser echo intensity information obtained by the 2D detector with the target depth information obtained by the 3D lidar. The result in different apertures was modified based on the principle of non-coherent synthetic aperture imaging to achieve 3D reconstruction of the target beyond the spatial resolution of 3D non-scanning lidar. Experimental results revealed that the proposed method could effectively improve the spatial resolution of 3D non-scanning lidar.

Key words: synthetic aperture imaging, common illumination source, super-resolution, 3D reconstruction, 3D lidar, 2D detector
