Method and system for identifying empty parking space and vehicle

Abstract

The embodiment of the invention provides a method and system for identifying an empty parking space and a vehicle, and belongs to the technical field of parking space monitoring. The method comprisesthe steps of determining position information of a parking space corner point by adopting a visual detection method based on a parking space picture collected by a vehicle; Based on the position information of the parking space corner points and a preset calibration model, obtaining world coordinates of the parking space corner points; Comparing the world coordinates of the parking space corner points with the actual coordinates of the preset parking space corner points, and under the condition that the world coordinates of the parking space corner points are consistent with the actual coordinates of the preset parking space corner points, identifying the parking space corresponding to the parking space corner points as a preset parking space; And identifying the preset parking space as anempty parking space based on the change relationship between the ultrasonic data and the driving distance and the actual coordinates of the corner point of the preset parking space. According to themethod, the empty parking space in the preset parking space can be accurately and effectively detected in automatic parking or passenger-replacing parking, intelligent detection of the empty parking space is achieved, and therefore a vehicle can be accurately parked on the preset parking space.

Description

technical field [0001] The invention relates to the technical field of parking space monitoring, in particular to a method, system and vehicle for identifying an empty parking space. Background technique [0002] At present, most of the vacant parking spaces on the market use ultrasonic detection solutions, but as long as the vacancy between two vehicles meets the width condition, it may be recognized as an empty parking space, so the vacant parking space identified may not actually belong to the preset parking space. Therefore, in the process of automatic parking or valet parking, if the car is parked according to the empty parking space detected by the ultrasonic detection scheme, it is very likely to park at any position other than the preset parking space, and the purpose of accurate and standardized parking cannot be achieved. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method for identifying empty parking...
