Vehicle real-time tracking method and device based on monitoring video

Abstract

The invention provides a vehicle real-time tracking method and device based on a monitoring video, and relates to the technical field of intelligent transportation, and the method comprises the steps:constructing a video network according to a plurality of video points; determining a reachable network of each video point according to the video network; determining a travel time interval of the target vehicle according to the reachable network; determining monitoring videos corresponding to the plurality of video points according to the reachable network in the travel time interval to performfeature extraction of the target vehicle; and when the features of the target vehicle are extracted, switching to the corresponding monitoring video for display. According to the invention, a topological relation graph between different video points is formed by constructing a video network, the travel time interval of the target vehicle is determined according to the video network, the subsequentvideo points are started timely to identify the target vehicle, rapid positioning of the vehicle is completed, basic data and a video AI technology are combined, rapid and stable tracking of the real-time trajectory of the vehicle is realized, and the vehicle real-time tracking method and device have a wide application prospect in urban management.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular, to a monitoring video-based real-time vehicle tracking method and device. Background technique [0002] In recent years, with the rapid development of my country's economy and the improvement of residents' living standards, automobiles, as an important means of transportation, have become more and more important in daily life. With the continuous growth of car ownership, various traffic problems such as illegal driving and random parking in urban road traffic are also increasing day by day, and the resulting traffic problems are becoming more and more serious. How to effectively supervise the driving on the road Vehicles are becoming more and more important. [0003] With the gradual improvement of our country's infrastructure, in the road traffic system, in order to better monitor road information, relevant departments have installed a large number of surveilla...

AI Technical Summary

Problems solved by technology

However, the existing cross-camera vehicle tracking effects are generally poor, and most rely on manual clicks to switch between videos; the rest rely on real-time GPS of the vehicle, which has low applicability; there are also pure video AI (Artificial Intelligence, artificial intelligence) recognition , but the video jumps a lot, and the landing effect is poor
