Method and device for detecting bus lane occupancy

Abstract

The invention provides a method and a device for detecting lane occupation of a bus lane. The method comprises the following steps: obtaining the position of a bus; judging whether the position of thebus is in a preset bus dedicated lane area or not; if the position of the bus is in the special lane area of the bus, obtaining an original image collected by a camera; determining a bus lane line area and a moving target area in the original image; Under the condition that the size of the moving target area is within a preset vehicle area size range, judging whether the area of an overlapped area of the bus lane area and the moving target area is greater than a preset threshold value or not; and if the area of the overlapped area is greater than a preset threshold value, determining a targetdetection area based on the overlapped area, performing vehicle detection in the target detection area, and after the vehicle area is detected, performing license plate recognition on the vehicle area to obtain a license plate number of a vehicle in the vehicle area. By applying the embodiment of the invention, the detection accuracy is improved in the process of detecting the occupation of the bus lane.

Description

technical field [0001] The invention relates to the technical field of traffic violation detection, in particular to a method and device for detecting bus lane occupation. Background technique [0002] Bus lanes are dedicated lanes for buses, usually only for buses. If other vehicles, such as motorcycles, tricycles or cars, are on the bus lane, it is illegal to occupy the lane. In order to ensure the normal operation of urban buses, the occupancy of bus lanes can be detected. [0003] The inventor found in the process of realizing the present invention that at present, the bus lane occupancy detection method usually determines that the bus lane is occupied by vehicles after detecting that the bus lane line area in the image is blocked. The line area may be blocked not only by vehicles, but also by objects on the road such as people, animals, and road railings, so the detection accuracy is not high. Contents of the invention [0004] The object of the present invention is...
