Abstract

In order to enhance the imaging speed of the 3D imaging lidar (light detection and ranging) and implement high-speed 3D imaging under static conditions, we propose a new 3D imaging lidar based on a laser diode and a high-speed 2D laser scanner. The proposed 3D imaging lidar is mainly composed of a transmitter, a laser scanner, a receiver and a processor. This paper introduces the components and principle of the proposed 3D imaging lidar first. And then some experiments have been carried out to evaluate the performance of the 3D imaging lidar, in terms of scanning field, measuring precision, scanning speed, image resolution and etc. The results show that the scanning field of the 3D imaging lidar is about 26°×12°, the measuring precision is better than 5 cm (4 m distance), the scanning speed is greater than 30 fps (frame per second) and the image resolution can reach 16×101. In addition, the 3D imaging lidar can obtain both the 3D image and intensity image for the given target at the same time.
