Vehicle parking behavior recognition system for urban environment based on machine vision

Abstract

The invention provides a vehicle parking behavior recognition system for urban environment based on machine vision. Monitoring equipment collects video images, the collected video images are accessedto an intelligent video analysis server to decode and display, user rules are set, then the area to be monitored in the video images, namely the detection area of a vehicle, is selected manually, andthe threshold value of vehicle parking time is set; according to video data in the monitoring area, vehicle detection is carried out by using a target detection algorithm to obtain accurate vehicle location information; meanwhile, the detected vehicle is tracked to obtain the motion trajectory of a vehicle object; according to motion trajectory information of the vehicle object, vehicle behavior is analyzed to judge the behavior of the vehicle, if preset rules are met, the alarm is triggered and a license plate number is recognized; otherwise, the current vehicle is filtered out and the next round of vehicle behavior recognition is carried out; and then the purpose of intelligent detection of the vehicle behavior in the fortification area is realized, the labor cost is effectively reduced,and the intelligence level and working efficiency of urban management are improved.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a machine vision-based behavior recognition system for parked vehicles in an urban environment. Background technique [0002] With the development of the economy, the continuous improvement of social living standards, and the rapid development of urbanization, the number of motor vehicles is increasing rapidly. The original urban planning is now difficult to meet the sharp increase in motor vehicle parking, and vehicles are parked randomly in the streets and alleys of the city. Phenomena are not uncommon, such as random parking on the street, random parking on prohibited sections, and random parking on sidewalks, which often cause road difficulties, pedestrians and vehicles competing for the road, and there are also potential safety hazards. In order to further strengthen urban management, improve urban quality, make reasonable use of road resources, standardize the o...

Problems solved by technology

[0002] With the development of the economy, the continuous improvement of social living standards, and the rapid development of urbanization, the number of motor vehicles is increasing rapidly. The original urban planning is now difficult to meet the sharp increase in motor vehicle parking, and vehicles are parked randomly in the streets and alleys of the city. Phenomena are not uncommon, such as random parking on the street, random parking on forbidden roads, and random parking on sidewalks, which often cause road difficulties, pedestrians and vehicles competing for the road, and there are also potential safety hazards

In order to further strengthen urban management, improve urban quality, make reasonable use of road resources, standardize the orderly parking of vehicles on main and secondary arterial roads and sidewalks, and effectively solve the problem of disorderly parking of vehicles in urban areas, the urban management department needs to carry out inspections of vehicles that are not parked on the berth lines that are not parked according to law. In the interior, illegally parked vehicles are photographed to obtain evidence according to the law, and the joint traffic police department is punished. Not only the labor cost is high, but also the cost of material and financial resources needs to be increased, and the work efficiency is low.
