Parking space recognition method and system for automatic parking

Abstract

The present invention relates to a parking space recognition method for automatic parking and a system thereof. The method includes: acquiring vehicle surrounding environment information, and obtaining parking space information according to the vehicle surrounding environment information, and the parking space information includes parking space parameters and parking space of each parking space Information on obstacles in the parking space; store the parking space information according to the obstacle information in the parking space; update the stored parking space parameters of each parking space in real time according to the vehicle movement situation, and update each stored parking space parameter in real time according to the vehicle movement situation and obstacle movement situation. Obstacle information in the parking space; determine the parking space and its distance to the vehicle according to the parking space parameters and obstacle information in each parking space updated in real time. The invention can update the obstacle information in the parking space in real time, and re-determine the parking space according to the obstacle information in the parking space, so as to avoid that a parking space cannot be identified after the obstacle in the parking space moves out of the parking space.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a parking space recognition method and system for automatic parking. Background technique [0002] The parking spaces for automatic parking usually use ultrasonic sensors, surround-view cameras or a combination of the two to comprehensively identify the parking spaces. Recognized parking spaces include vertical, horizontal and inclined parking spaces. The usual identification strategy is that when a car passes by, there is a certain parking space and there are no obstacles in the space, it is considered as a space parking space; if there is a parking space line on the ground and there is no obstacle in the parking space line, it is considered as a parking space line parking space. Both parking spaces are parking spaces. However, if there are obstacles in the parking space, such as cars, bicycles, motorcycles, pedestrians, small animals and other moving objects, the ca...

AI Technical Summary

Problems solved by technology

However, if there are obstacles in the parking space, such as cars, bicycles, motorcycles, pedestrians, small animals and other moving objects, the car will not recognize the parking spaces with obstacles when passing the parking space, even if the obstacles are removed after the car passes the parking space. Moving out of the parking space will no longer affect the automatic parking system. After the car is parked in the original invalid parking space, the original invalid parking space cannot become a parking space

[0003] Therefore, the above-mentioned prior art scheme cannot update the obstacle information in the parking space in real time, resulting in a parking space that cannot be identified after the obstacle in the parking space is removed from an invalid parking space.
