Problems solved by technology
[0004] At present, when on the expressway, manual real-time monitoring or offline inspections are often used to report construction incidents for early warning. The real-time performance is poor, which leads to a high probability of traffic accidents in the construction section, which affects road traffic safety.

Embodiment Construction
[0061] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0062] According to the data provided by the Traffic Information Center of the Scientific Research Institute of the Ministry of Transport, the number of motor vehicles on expressways has continued to grow steadily. The number of trucks in 26 provinces and cities across the country is about 1.5 billion, and the average daily volume of trucks is 4.93 million. times, a year-on-year increase of 14%. In order to ensure the normal passage of the expressway, it ...

The invention relates to the technical field of intelligent traffic, and provides a video-based road construction early warning method and device, and the method comprises the steps: determining the weight between anchor point frames of a plurality of training samples and a pre-marked real frame based on the distance and intersection-to-union ratio between the anchor point frames and the pre-marked real frame, generating a weighted bipartite graph, and obtaining a road construction detection model based on the weighted bipartite graph training. By utilizing the model, each feature map of the inner table road construction features of each video frame can be accurately extracted, and a feature map set is obtained; and for the feature map set corresponding to each video frame, the inter-frame residual network is adopted to detect whether the road construction event occurs, and the inter-frame residual network is combined with the construction features of the two video frames at different moments, so that the accuracy of road construction event detection is improved, and when the road construction event is detected, the accuracy of road construction event detection is improved. And the construction early warning message is pushed in time, so that the normal passing of the expressway is ensured, and the probability of traffic accidents is reduced.
Description
technical field [0001] The present application relates to the technical field of intelligent transportation, and in particular, to a video-based road construction early warning method and device. Background technique [0002] With the continuous development of the economy, the number of motor vehicles has continued to grow, and the traffic volume of the road network has increased rapidly and steadily, increasing the bearing capacity of the road surface. Especially on highways with large traffic flow, due to the high speed of vehicles, the large number of large trucks in the past, and the defects in the construction process, the highways will be damaged to varying degrees. Carry out maintenance. [0003] When maintaining and repairing expressways, some construction features are often set, such as roadblocks, construction vehicles, construction signs, construction personnel, etc., to remind vehicles to slow down and detour. However, due to the large traffic flow on the expre...
