Roadside parking detection method and device based on vehicle characteristic analysis

Abstract

The invention provides a roadside parking detection method based on vehicle characteristic analysis. The roadside parking detection method comprises the steps of: acquiring a first continuous scene image; performing suspected parking area detection to obtain parking space coordinate information; performing license plate identification and vehicle model identification by using a second video camerato automatically zoom in a parking space coordinate information area, acquiring the optimal license plate identification and vehicle model identification results, generating a vehicle ID, and performing direction detection; acquiring a third continuous scene image by using a first video camera if the direction is driving in, performing vehicle ID trajectory detection, and storing the vehicle ID if the trajectory is not updated in a period of time, otherwise, deleting the vehicle ID; and acquiring a fourth continuous scene image by using the second video camera if the direction is driving out,performing vehicle ID trajectory detection, comparing the vehicle ID with vehicle IDs in a database if the vehicle ID trajectory is far away from parking space coordinates, and outputting a result. Compared with the prior art, the roadside parking detection method and a roadside parking detection device can effectively solve the problems of license plate occlusion and unlicensed vehicles in roadside parking detection.

Description

Technical field [0001] The invention relates to image processing, video monitoring and security, in particular to a roadside parking detection method and device. Background technique [0002] With the increasing number of cars, on-street parking has become one of the urgent problems to be solved, which has attracted the attention of traffic management departments. Traditional roadside parking detection is mainly based on enclosures, ground sensing devices and handhelds, which are inefficient and cannot realize real-time monitoring, which greatly wastes the manpower and financial resources of related departments. [0003] In recent years, the method of roadside parking detection based on surveillance video has received great attention. This method has the advantages of high accuracy, good real-time performance, low cost, and easy collection of evidence. According to the location where the surveillance camera is installed, there are roadside low pole solutions (installation height 0...
