Intelligent monitoring method and system for highway road

Abstract

The invention discloses an intelligent monitoring method and system for highway road. The system comprises an acquisition end, a server end and a client which are sequentially connected. The method comprises the steps of simultaneously receiving high-definition video data or infrared video data in two directions of the road by the acquisition end, performing data pre-processing on the high-definition video data or the infrared video data, and extracting a video frame to obtain picture data; inputting the picture data to a deep convolutional neural network which is trained already for detectionto obtain a vehicle detection result, a lane line detection result and an environmental visibility detection result; analyzing an abnormal traffic state according to the vehicle detection result andthe lane line detection result to obtain a grading early-warning result or a warning result for displaying, and performing real-time active early warning or warning on the vehicle, wherein the abnormal traffic state comprises vehicle violation, a fault and an accident; and obtaining and displaying a grading guidance result according to the environmental visibility detection result, and performingreal-time active guidance on the vehicle.

Description

Technical field [0001] The invention belongs to the technical field of intelligent transportation facilities, and particularly relates to an intelligent monitoring method and system for highway roads. Background technique [0002] The expressway is a completely closed, all-overpass road. Vehicles running on the expressway run fast and have a large traffic volume. Its ideal characteristics are "safe, fast, efficient, comfortable and convenient". However, with the continuous growth of traffic demand and the occurrence of congestion, accidents and pollution, highway monitoring systems have become the focus of attention of transportation facilities construction and management departments. [0003] The highway monitoring system is to solve the two main problems in highway operation-congestion and safety. The purpose of the monitoring system is to ensure safe driving and smooth roads. The highway monitoring system should have the following three functions: information collection, time ...

AI Technical Summary

Problems solved by technology

[0006] Second, there is a lack of timely warning and guidance for violating vehicles

For the driver’s behavior of violating the rules and regulations on the expressway, the driver is only punished afterwards through administrative punishment. There is no on-site warning device or mobile client to remind the driver in time to prohibit the driver from making illegal actions on the expressway when the vehicle violates the rules. Violations, the existing highway monitoring system cannot prevent the occurrence of violations in time, cannot correct the violations in time, and cannot effectively prevent the occurrence of traffic accidents

[0007] Third, there is a lack of active prevention of vehicle violations and traffic accidents

Most of the existing expressway monitoring systems are used for post-event punishment of vehicle violations, or for judging accidents after accidents and making emergency plans. The prevention of vehicle violations and traffic accidents is only passive by setting fixed warning signs. There is a lack of intelligent monitoring methods and systems for proactively preventing vehicle violations and traffic accidents through expressway monitoring facilities.
