DSRC road detection system based on double multi-line laser radars

Abstract

The invention discloses a DSRC road detection system based on double multi-line laser radars, and the multi-line laser radars are arranged at the two sides of a road at equal intervals, and are used for continuously emitting laser at preset time intervals. The image collector is used for collecting an image of the laser irradiation position; the processor is connected with the image collector and is used for storing and sending collected information; the DSRC communication module is used for receiving and sending the road information sent by the processor and transmitting the road information to passing vehicles; the traffic management terminal obtains the information collected by the processor in real time, and generates corresponding alarm information for the road section with abnormal road condition information and the snapshot vehicle according to the collected information. According to the invention, the three-dimensional information of the measured surrounding object can be scanned, so that the surrounding environment can be monitored in real time, the effect of the collected point cloud data is fully played, the information is ensured to be transmitted to the passing vehicles in real time, and accidents are reduced.

Description

technical field [0001] The present invention relates to the technical field of road detection, and more specifically relates to a DSRC road detection system based on dual multi-line laser radar. Background technique [0002] At present, the mileage of highways in my country is increasing rapidly, the traffic flow is increasing day by day, and the workload and difficulty of road surface maintenance management are increasing sharply. Road surface smoothness, rutting depth, and damage state are important indicators for evaluating road conditions and the premise of implementing scientific road maintenance management. The roughness and damage state of the road surface not only directly affect the safety and comfort of driving, but also seriously endanger the integrity and stability of the road structure. Therefore, it is necessary to regularly detect the smoothness and damage state of the road surface; however, the traditional detection method takes a long time to detect, is labo...

Problems solved by technology

[0005] Although the current traffic information release method is relatively intelligent, it is not timely enough. It requires front-end and back-end communication and data processing, which takes a certain amount of time. The driver's reading of the sign information will distract the driver from concentrating.
