Problems solved by technology

The disadvantage of lidar is that it is greatly affected by the environment and climate when working, and its beam is extremely narrow, it is very difficult to search for targets in space, which directly affects the interception probability and detection efficiency of non-cooperative targets, and can only search and capture in a small range target, while its cost is very expensive, and related applications cannot be widely promoted

Abstract

The invention discloses a method for simulating laser radar data based on multi-depth-camera splicing. Through the combination and splicing of a plurality of depth cameras according to the specified positions, barriers in a range greater than 90 degrees and less than 6 meters ahead a robot can be detected, and the operation of the laser radar simulation can be realized. The data acquisition of the depth cameras is not influenced by environment, and the data error is small. The method has the advantage of low cost, and can fill the shortcomings of laser radar.

Description

technical field [0001] The invention relates to a simulation method, in particular to a method for splicing simulated lidar data based on multiple depth cameras. Background technique [0002] With the development of science and technology and the wide application of computers and high-tech, digital stereo photogrammetry has gradually developed and matured. Lidar is a radar system that works in the infrared to ultraviolet spectrum. Then compare the received signal reflected from the target with the transmitted signal, and after proper processing, the relevant information of the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even shape parameters, so that Detect and identify obstacles. Depth cameras based on the three technologies of binocular, structured light and TOF (time-of-flight ranging) are also becoming more mature, which can provide depth information for smaller vision. [0003] Lidar is a radar system that emits detection sig...
