Example Embodiment
[0045]Example 1:
[0046]Such asfigure 1 As shown, a traffic light device based on lidar of the present invention includes a traffic light module, a lidar module, a positioning module, an edge processing module communication module, and a housing. The traffic light module, lidar module, and positioning module are all connected to the edge processor The edge processor is electrically connected to the communication module, and the casing encapsulates the traffic light module, the laser radar module, the positioning module, the edge processor and the communication module into a set of devices.
[0047]The traffic light module is a conventional traffic light module that can display information such as traffic light status and time. The module can obtain its own traffic light status to form traffic light information, and send the traffic light information to the edge processor.
[0048]The lidar module is used to measure the position, motion state and shape of the vehicle by detecting the echo si...
Example Embodiment
[0055]Example 2:
[0056]Such asfigure 2As shown, the traffic light system based on lidar of the present invention includes a traffic light device and a cloud platform. The traffic light device is a traffic light device based on lidar disclosed in the embodiment. Each intersection is equipped with a set of traffic light devices and two lidars. The effective scanning area of the modules is not repeated, and the scanning area of one of the lidar modules can cover the scanning blind area of the other lidar module; the cloud platform is wirelessly connected with the above-mentioned traffic light device.
[0057]The cloud platform is used to perform the following operations:
[0058]Store and parse the monitoring information to generate a traffic light system management table, the traffic light system management table includes traffic light position information, traffic flow information, and fault information, the above information is respectively bound to time;
[0059]Based on real-time traf...
