Abstract

The invention discloses a laser-radar-based traffic light device and system, belongs to the technical field of traffic light control, and aims to solve the technical problem of how to combine the laser radar with traffic lights to regulate and control traffic signals so as to relieve road traffic pressure. A traffic light module is used for acquiring the state of traffic lights to form traffic light information; a laser radar module is used for measuring the position, the motion state and the shape of the vehicle by detecting an echo signal of the emitted laser beam to form laser radar information; a positioning module is used for acquiring positioning information of the traffic light module; an edge processor is used for jointly packaging the laser radar information, the positioning information and the traffic light information into monitoring information; a communication module is used for transmitting data information in a wireless communication mode; and a shell is used for packaging the modules, the laser radar module, the positioning module, the edge processor and the communication module into a whole. The system comprises a cloud platform and the traffic light device.

Description

technical field [0001] The invention relates to the technical field of traffic light control, in particular to a laser radar-based traffic light device and system. Background technique [0002] During the morning peak and evening peak hours, the traffic lights at most intersections are changed with a fixed control light duration, resulting in some intersections with no vehicles but a longer passing time, and some intersections with a large traffic flow and a shorter passing time, which greatly increases the traffic pressure. And the driver often has a traffic accident because of robbing a traffic light when passing, causing more serious impact. [0003] LiDAR is mainly used in fields such as military and civilian geographic mapping (GIS), such as geological mapping, monitoring tree growth, and measuring the progress of construction projects. With the rise of autonomous driving, lidar has a longer detection distance and higher accuracy than other types of autonomous driving ...
