Automatic parking space detection method, electronic radar system and storage medium

Abstract

The invention relates to an automatic parking space detection method, an electronic radar system and a storage medium. The method includes: starting the parking space search function, switching the radar system to the parking space search working mode, and starting the parking mode algorithm at the same time; target detection, judging Whether there are multiple targets in a distance resolution unit at the same time, if so, distinguish multiple targets and output multiple target information, otherwise, go to the next step; judge whether the parking space search function is completed, if so, restore the normal long-distance detection mode , otherwise, return to the previous step. In the radar system of the present invention, by switching the working mode, without increasing the scanning bandwidth, the detection accuracy and resolution of the short-distance are improved, so as to realize the parking space search function in APA and VPA, and realize relatively fast detection without relying on image requirements. On the basis of a large-scale parking space search, it can also adapt to changes in various environments, and can detect and feed back various emergency situations during the parking process in time for background processing.

Description

technical field [0001] The invention relates to the technical field of parking space detection, in particular to an automatic parking space detection method, an electronic radar system and a storage medium. Background technique [0002] With the development of autonomous driving technology, more and more models are equipped with automatic parking system (AutoParking Assistance) or valet parking system (Valet Parking Assistance), through the cooperation of camera and ultrasonic radar, complete parking space search and environmental perception , and then realize the parking control. However, in the parking system, the disadvantages of the ultrasonic sensor are obvious: its detection distance is limited and the speed information of the target cannot be obtained, and it is easily disturbed by the external environment, so it cannot meet the detection requirements in complex scenes or in bad weather, such as in underground garages Or complete accurate parking space search and eme...

Problems solved by technology

However, the current millimeter-wave radar is limited by the bandwidth and regulations, and the distance detection accuracy and resolution are limited, which is not enough to fully meet the parking space search requirements of automatic parking.
