Method and device for determining vehicle behavior based on pedestrian re-identification

Abstract

The embodiment of the invention provides a method and device for determining vehicle behaviors based on pedestrian re-identification, and the method comprises the steps: obtaining an image of a predetermined monitoring region, carrying out the recognition of a current image, and judging whether a vehicle exists in the current image or not; if yes, obtaining a first image set containing the moving state of the vehicle in a preset time period, and determining portrait information of a driver of the vehicle through a pedestrian re-recognition algorithm; determining a first distance change trend of the distance between the driver and the vehicle and a second distance change trend of the distance between the vehicle and the parking space; and according to the first distance change trend and the second distance change trend, determining entry and exit behaviors of the vehicle. According to the method and the device, the entrance and exit behaviors of the vehicle can be accurately determined without being limited by the license plate number, and the situation that the vehicle behavior cannot be determined due to the fact that the vehicle image cannot be acquired due to the limitation of factors such as the shooting angle of the monitoring camera and the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent parking management, in particular to a method and device for determining vehicle behavior based on pedestrian re-identification. Background technique [0002] Today, with the rapid economic development, people's living standards and income are constantly improving, and the number of urban motor vehicles is also increasing rapidly. The contradiction between parking needs is also becoming increasingly acute. Especially on both sides of urban roads, due to the scarcity of roadside parking spaces and the weak traffic safety awareness of motor vehicle drivers, urban roadside parking and illegal parking on the roadside have become one of the chronic problems of urban management, which has caused traffic congestion and other problems Seriously restricting the green and rapid development of the city, seriously affecting the appearance of the city and the living environment of residents, the governanc...

Problems solved by technology

[0003] With the maturity of high-level video technology, real-time automatic monitoring of roadside parking lots has become the main way of roadside parking management. However, due to the constraints of on-site construction and environmental factors, some surveillance cameras may fail to supervise roadside parking behaviors. At the same time, it often happens that the target vehicle is blocked by other large vehicles and cannot be supervised. In addition, the existing high-level video technology supervision of roadside parking behavior often relies on identifying the license plate number information of the target vehicle. However, due to monitoring The camera shooting angle is limited, and when the target vehicle is parked in the parking lot, the license plate number of the target vehicle cannot be clearly captured
