Road exit lane traffic flow overflow real-time detection method based on video analysis

Abstract

The invention belongs to the field of computer vision, and particularly relates to a road exit lane traffic flow overflow real-time detection method based on video analysis. The method comprises the following steps: configuring an electric police or monitoring equipment and a detection area, calculating up and down sub-sections, opening a video channel, preprocessing an image, detecting a vehicle, tracking the vehicle, calculating a traffic flow direction, resetting coordinates of the up and down sub-sections, calculating an exit lane overflow detection dependency parameter, normalizing the exit lane overflow detection parameter, and calculating an exit lane overflow index. According to the scheme, the problem that traffic flow overflow easily occurs at urban road intersections is solved, real-time recognition of exit lane overflow is achieved through a large number of existing road intersection electric alarms and monitoring equipment by means of the machine learning technology and the computer graphic image technology, a traffic control department is assisted in finding alarms in time, a basis is provided for formulating a reasonable release strategy, safe and orderly operation of urban roads is guaranteed, and the production efficiency of the whole city is improved.

Description

technical field [0001] The invention belongs to the field of computer vision, in particular to a video analysis-based real-time detection method for vehicle flow overflow at road exits. Background technique [0002] At present, with the continuous increase of the number of vehicles in our country and the continuous advancement of urbanization, urban roads are becoming more and more congested. In particular, the imperfect design of previous urban roads resulted in more short-distance intersections, which are extremely prone to congestion and accidents. How to timely discover congestion and accidents at intersections is a difficult point for traffic managers. The exit overflow event can reflect the current state of the intersection. If an exit overflow occurs at an intersection, it indicates that there is congestion or an accident downstream. If the exit overflow event can be reported in time, the traffic control department will obtain the police notification in time and dea...
