On-street parking management method based on multi-camera image joint processing

Abstract

The invention relates to a roadside parking management method based on joint processing of multi-camera images: the camera group module obtains and stores image information of a target vehicle; the first-level image processing module tracks the trajectory of the target vehicle to obtain its position coordinates and range in the image information, And extract the position information of the target vehicle in the panoramic image and map it to the corresponding parking camera to obtain the corresponding parking camera image information; segment the target vehicle image in the panoramic image and compare the features of the corresponding parking camera image to further obtain the target Vehicle entry / exit information; the secondary image processing module performs secondary processing according to the confidence of the primary processing to improve the accuracy of analysis. The advantage is that the joint analysis of the panoramic camera and the parking camera not only improves the accuracy of license plate recognition, the accuracy of target vehicle entry / exit motion capture, and calculation efficiency, but also can perform full-process image analysis on parking events, achieving full coverage of the parking process, and Efficient backtracking of parking events.

Description

technical field [0001] The invention relates to a roadside parking management method based on multi-camera image joint processing. Background technique [0002] In the urban intelligent transportation system, the management of the parking lot occupies a very important proportion. With the increasing occupancy of urban motor vehicles, the parking lot is no longer limited to the original model, and the roadside parking lot has assumed an increasingly important role, and the requirements for intelligent management of the roadside parking lot are also increasing. The more accurate and faster. At present, the main technical realization of on-street parking management is the intelligent management system based on geomagnetism, or the intelligent management system based on the combination of geomagnetism and video, and even in some places, it is still a purely manual management method. The management of urban parking lots, especially intelligent management, has become more and mo...

Problems solved by technology

[0003] In the parallel parking scene of roadside parking, the license plate is easily blocked when the vehicle enters the venue, the accuracy of license plate recognition is not high, the motion capture of the vehicle entering / exiting is not accurate, and the accuracy of the entering / exiting record is difficult to control, resulting in the inability to obtain all Accurate monitoring images of the parking area, and thus inaccurate judgments on the information of the parking incident; this will bring a lot of inconvenience to the later evidence collection of parking incident disputes
