Abstract

The invention discloses a two-dimensional laser radar railway obstacle detection system in the technical field of railway obstacle detection, comprising an adjustment platform, a control arithmetic unit and an alarm device are installed on the left side of the top of the adjustment platform, and the control arithmetic unit is located at On the left side of the alarm device, a two-dimensional laser radar is connected to the center of the top of the adjustment platform through screws, a detection method of a two-dimensional laser radar railway obstacle detection system, and the detection method of the two-dimensional laser radar railway obstacle detection system The specific steps of the method are as follows: S1: Adjust the two-dimensional laser radar parallel to the rail surface; S2: Calibrate the radar two-dimensional plane coordinate system; S3: Set the protection area; S5: Determine and confirm obstacles. This scheme can filter out interference and realize All-weather, under various conditions for detection, improve the safety of the railway.

Description

technical field [0001] The invention relates to the technical field of railway obstacle detection, in particular to a two-dimensional laser radar railway obstacle detection system and a detection method thereof. Background technique [0002] Rockfall or pedestrians drop large objects on the rail surface frequently occur along the railway in dangerous mountainous areas, which seriously affects the safety of train driving. The existing video surveillance is greatly affected by the environment, and the construction cost of the anti-zone vibration optical cable is high and easy to be damaged. For this reason, We propose a 2D lidar railway obstacle detection system and its detection method. Contents of the invention [0003] The purpose of the present invention is to provide a two-dimensional laser radar railway obstacle detection system and its detection method to solve the problems of the existing video surveillance proposed in the above background technology, which are great...
