Parking space recognition precision detection method and device and automatic driving vehicle

Abstract

The invention discloses a parking space recognition precision detection method and device and an automatic driving vehicle, and the method comprises the steps: obtaining a target vertex coordinate of at least one parking space in a vehicle coordinate system on a test field recognized by an automatic parking system, wherein the target vertex coordinate is recognized in the process that the vehicle travels forwards from the initial position on the test field, and the initial position is the geographic position where the vehicle is located when the straight line where the midpoints of the two rear wheels are located coincides with the straight line where the first side of a reference parking space is located and the initial course of the vehicle is parallel to the second side of the reference parking space; acquiring a first actual distance from the midpoint of the rear wheel closest to the second side to the second edge, a second actual distance and the length of the target edge, wherein the second actual distance is 1 / 2 of the distance between the midpoints of the two rear wheels; and according to the target vertex coordinate, the first actual distance, the second actual distance and the length of the target edge, determining the parking space recognition precision of the automatic parking system. Through the method, parking space identification precision detection for different scenes can be realized.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a detection method and device for recognition accuracy of parking spaces and an automatic driving vehicle. Background technique [0002] Autonomous driving, also known as unmanned driving, relies on the cooperation of artificial intelligence, visual computing, radar, monitoring devices and global positioning systems, allowing computers to automatically and safely operate motor vehicles without any active human operation. In the automatic parking process of automatic driving, parking space recognition is very critical, because only by accurately identifying the coordinate information of the parking space, can the parking path plan be accurately carried out to avoid the failure to park in the parking space due to recognition errors Center situation. [0003] In practical applications, the accuracy of parking space recognition is affected by various factors such a...
