Method, system and vehicle for identifying empty parking space

Abstract

Embodiments of the present invention provide a method, system and vehicle for identifying an empty parking space, which belong to the technical field of parking space monitoring. The method includes: based on the parking space picture collected by the vehicle, using a visual detection method to determine the position information of the corner point of the parking space; based on the position information of the corner point of the parking space and a preset calibration model, obtaining the world coordinates of the corner point of the parking space; comparing The world coordinates of the corner point of the parking space and the actual coordinates of the corner point of the preset parking space, and when the world coordinates of the corner point of the parking space are consistent with the actual coordinates of the corner point of the preset parking space, identify the corner point of the parking space The corresponding parking space is a preset parking space; and based on the variation relationship between the ultrasonic data and the driving distance and the actual coordinates of the corner points of the preset parking space, identifying that the preset parking space is an empty parking space. The method can accurately and effectively detect empty parking spaces in preset parking spaces during automatic parking or valet parking, and realize intelligent detection of empty parking spaces, so that vehicles can be accurately parked in the preset parking spaces.

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 precise 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 ...
