Abstract

The invention discloses a 3D laser radar imaging system which comprises a USB camera and a wordline laser. The imaging part of the USB camera and the wordline laser are combined to simulate a 3D laser radar to realize three-dimensional imaging. The imaging part of the camera acquires the two-dimensional distribution information of a scanned target. The distance information of the measured target is captured by combining the laser with a triangulation algorithm. The three-dimensional information of an object space is reproduced through a three-dimensional imaging algorithm. According to the invention, on the premise that 3D imaging is well realized, the system has greatly reduced cost compared with a similar laser radar.

Description

technical field [0001] The invention relates to the technical field of radar imaging, in particular to a 3D laser radar imaging system. Background technique [0002] In the field of modern detection science, radar imaging is an important research content. It broadens the concept of traditional radar and enables people to see more detailed target information through the radar screen. It has working characteristics such as all-weather and long-distance work. Widely used in military and civilian fields, including battlefield reconnaissance, guidance, target recognition, resource survey, terrain surveying and mapping, etc. [0003] 3D lidar is a comprehensive imaging radar involving multiple directions and multiple fields. Utilizing the directional, coherent, monochromatic and infrared all-weather characteristics of laser, 3D lidar imaging systems are widely used in civil or military fields such as geological exploration, missile tracking, and aerospace. Building a 3D lidar im...
