Method for identifying vehicles entering and exiting parking spaces

Abstract

The invention discloses a method for identifying vehicles entering and exiting parking spaces, and the method comprises the steps: obtaining a monitoring image, and building a two-dimensional coordinate system; determining responsibility parking spaces, wherein each responsibility parking space obtains a corresponding coordinate area; intercepting a field image from the field video every a presetperiod to obtain a vehicle two-dimensional coordinate of each vehicle in each field image; judging whether the two-dimensional coordinates of the vehicle in each field image have intersection points with the parking space coordinate set or not, obtaining a coordinate intersection, and calculating a coordinate intersection area, namely an overlapping area of the vehicle and the parking space; and calculating the overlap ratio of the vehicle and the parking space coordinate set according to the ratio of the coordinate intersection area to the vehicle area, and judging the state of the vehicle according to the change trend of the overlap ratio in the continuous multi-frame images. The method for identifying vehicles entering and exiting parking spaces is completed through a camera and an analysis module, management personnel do not need to be configured on site, manpower management cost can be greatly reduced, and higher identification efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent parking, in particular to a method for identifying vehicles entering and exiting parking spaces. Background technique [0002] With the improvement of the urbanization process, there are more and more parking spaces in the city. Most of the parking spaces are paid parking, that is, parking fees will occur within a specified time period or during all time periods. The existing parking charging system is significantly different according to the location of the parking space. For example, the parking spaces on both sides of the road are often equipped with geomagnetic devices on the parking spaces. At least one parking officer is arranged near the parking space. Confirm entry and exit times. The other is the parking space in the parking lot. This type of parking space is often set in an underground garage or a ground garage, with a parking lot entrance and a parking lot exit. The entry and depar...

AI Technical Summary

Problems solved by technology

[0004] For roadside parking, the conventional method in the prior art is to confirm the entry and exit time of the vehicle through geomagnetic induction and manual operation of the administrator; this method has a low degree of automation and requires a lot of labor costs
