Problems solved by technology

[0004] At present, the illegal driving of vehicles is only for early warning and off-site law enforcement for illegal driving such as "pressing the line" and "reversing". "Illegal acts or abnormal detours at intersections, these abnormal driving will aggravate intersection congestion and accidents

Embodiment Construction

[0054] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] The abnormal driving early warning method based on the reasonable driving range of vehicles at the intersection includes the following steps:

[0056] Step 1. Determine the vehicle trajectories at the intersection based on the historical intersection monitoring video, and classify the vehicle trajectory type patterns through hierarchical clustering and intersection channelization.

[0057] Step 1-1, based on the historical video of the intersection monitoring unit time period, extract the original trajectory points under different vehicle IDs, denoted as P(f,x,y), where f represents the number of frames, x and y represent the coordinate values, and then pass Initial data cleaning determines a single vehicle trajectory with different vehicle IDs, denoted as TR={P|p i , 1≤i≤n, n is the number of trajectory points}; in general, ...

Abstract

Disclosed is a method for warning abnormal driving based on a reasonable driving range of intersection vehicles. Intersection vehicle trajectories are comprehensively analyzed based on historical surveillance video data by a hierarchical algorithm, an LCSS algorithm, or DTW algorithm to determine a reasonable vehicle trajectory range at an intersection in each flow direction, thereby realizing real-time warning of abnormal moving vehicles based on monitoring videos, efficiently judging illegal behaviors, knowing intersection anomalies in time, improving the efficiency of traffic management, strengthening the intensity of black spot control at the intersection, and providing a safe and smooth traffic environment for the intersection.

Description

technical field [0001] The invention relates to the field of vehicle driving monitoring, in particular to an early warning method for abnormal driving based on the reasonable driving range of vehicles at intersections. Background technique [0002] With the acceleration of urbanization and the continuous increase of car ownership, urban road traffic conditions have become very complicated. In the urban road network, the intersection is the "throat" of urban traffic and the core of the entire urban traffic. Whether the vehicles at the intersection drive in order and in accordance with regulations is the key factor leading to traffic accidents and traffic congestion. Therefore, how to control the traffic at the intersection? Trajectory discrimination and early warning of violating vehicles are one of the key points to alleviate traffic problems in urban areas. [0003] The development of intelligent transportation at the present stage and the popularization of electronic poli...
