Abstract

The embodiments of the invention disclose a multi-radar detection method and a device. The method comprises the following steps: building the angle correspondence between the detection angles of every two adjacent laser radars in multiple laser radars to make the echo formed through first reflection of a probe beam emitted by one laser radar via an obstacle beyond the reception range of another laser radar; and in the detection process of each laser radar, making the detection angles of every two adjacent laser radars synchronized based on the angle correspondence. Through the embodiments of the invention, the problem of interference between adjacent laser radars during multi-radar detection can be solved, and measurement is accurate.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a multi-radar detection method and device. Background technique [0002] Transportation plays an important role in the national economy, and transportation safety is a major issue related to the national economy and people's livelihood. At present, Chinese railway companies have begun to use laser radar to scan and measure within the safety limits of railway traffic to find obstacles that exceed the size of the safe range and avoid danger to high-speed trains. [0003] At present, this line obstacle safety monitoring system collects echo distance, pan-tilt direction angle information, and relative position information between the lidar and the monitoring area, determines the position, speed and direction of obstacles through calculation, and analyzes the impact of obstacles on driving safety. level of threat. [0004] In practical applications, due to the use of the same type...
