Parking behavior judgment method and intelligent parking system

Abstract

The invention provides a parking behavior judgment method and an intelligent parking system, and the method comprises the steps: detecting and recognizing a vehicle, and obtaining a detection binding frame and parameters of the vehicle; setting a reference line segment according to the position of the vehicle parking space, and calculating the length of the reference line segment; calculating the ratio of the area defined by the binding frame and the reference line segment to the overall area of the binding frame; and judging the parking behavior according to the ratio change. The method has the beneficial effects that on the basis of a video shooting detection method, whether the vehicle enters the parking area or not is judged according to the ratio of the area defined by the parking reference line segment and the vehicle detection binding frame to the area of the whole binding frame, so that the calculation complexity of roadside parking behavior analysis is effectively reduced, and the computing resource demand degree is greatly reduced; detection of roadside parking behaviors under long distance and high overlapping degree can be realized, and the number of detected parking spaces is increased; and according to the real-time change of the occupancy, the vehicle parking information is monitored in real time, and the accuracy of parking space detection is improved.

Description

technical field [0001] The present invention relates to the field of smart parking, in particular to a parking behavior judging method and a smart parking system based on the ratio of the overlapping area of ​​a vehicle detection frame and a parking space. Background technique [0002] Smart parking is an important part of a smart city. It mainly refers to the comprehensive application of wireless communication technology, mobile terminal technology, GPS positioning technology, GIS technology, etc. to the collection, management, query, reservation and navigation services of urban parking spaces, so as to realize parking spaces. The integration of real-time resource update, query, reservation and navigation services can maximize the utilization rate of parking space resources, maximize the profit of the parking lot and optimize the parking service for car owners. On-street smart parking is an important part of the development of smart parking. On-street smart parking is mainl...

AI Technical Summary

Problems solved by technology

The detection accuracy of geomagnetic parking space is high, but the battery needs to be replaced regularly, and the replacement of the battery causes high pollution; it also needs to set up a relay receiver, and the manufacturing cost is high; the wireless signal is easily interfered, resulting in wrong parking information; Maintenance, when repairing the pavement, is vulnerable to damage or needs to be removed

[0004] The video detector does not need to dig the road to install equipment, and does not need to configure and replace the battery, which solves some problems of geomagnetic detection. However, the video detector is greatly affected by the environment, and currently it can only detect two or so parking spaces. , the detection of parking spaces is inaccurate; the current algorithm for judging vehicle behavior in overlapping areas cannot be solved well
