Roadside parking space judgment method and intelligent parking system

Abstract

The invention provides a roadside parking space judgment method and an intelligent parking system, and the method at least comprises the following steps: detecting and recognizing a vehicle, obtaining a detection binding frame of the vehicle, and calculating the parameters of the binding frame; calibrating a parking space reference point according to the vehicle parking space, and obtaining the coordinate of the parking space reference point relative to the vehicle binding frame; calculating a relative position relationship between the border of the binding frame and the parking space reference point; and obtaining the parking space of the vehicle according to the numerical value comparison of the relative position. The method has the beneficial effects that on the basis of a video shooting detection method, the parking space is judged by utilizing the relative position change of the calibrated parking space reference point / line and the vehicle binding frame, so that the calculation complexity for determining roadside vehicle parking position analysis is effectively reduced, and the calculation resource demand degree is greatly reduced; roadside vehicle parking positions can be detected in a long-distance and high-overlapping-degree mode, and the number of detected parking spaces is increased; and no extra equipment needs to be installed for the parking space where the roadside parking vehicle is located, and cost is reduced.

Description

technical field [0001] The invention relates to the field of smart parking, in particular to a method for judging a roadside parking space based on the relative position of the bottom edge of a vehicle detection frame and a smart parking system. 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 mainly based on ...

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
