Roadside parking management method and device

Abstract

The embodiment of the invention provides a roadside parking management method and device, and the method comprises the steps: obtaining images collected by a first camera and a plurality of second cameras in a preset image collection region, carrying out the distortion correction of the images collected by the first camera, and obtaining corrected images; determining a first shooting mapping areaof each second camera in the corrected images; determining a second shooting mapping area of each second camera containing the vehicle target in the corrected images; determining an identification area in the shot image of each corresponding second camera according to each second shooting mapping area; recognizing feature information of the vehicle target according to the determined recognition areas in the shot images of the second cameras; and performing parking management on the vehicle target according to the feature information of the vehicle target. Through the scheme, accurate identification of the vehicle target is realized, and the accuracy of identifying the vehicle target is greatly improved.

Description

technical field [0001] The invention relates to the technical field of intelligent parking management, in particular to a method and device for on-street parking management. 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 governance of urban roadside parking and illega...

Problems solved by technology

In parking management, if the focal length of the monitoring camera is short, although the parking behavior of the vehicle can be clearly judged, it is difficult to take into account the collection of vehicle characteristic information, especially in bad weather or insufficient light. It is more difficult to identify vehicle characteristics, such as the license plate number Wait

However, if a telephoto camera is used, although the characteristics of the vehicle can be clearly collected, sometimes it is impossible to obtain a complete picture of the vehicle. This situation is like the vehicle being blocked, thereby reducing the recognition rate of the vehicle target, and when the vehicle is not parked according to the berth line. It is very likely that the telephoto surveillance camera can only collect part of the vehicle image, which causes great difficulties in vehicle target detection and parking behavior judgment

Obviously, in the scene where the high-position video equipment is placed on the opposite side of the roadside parking space, it is difficult for a single type of camera to perfectly meet the needs of the scene
