Abstract

The present disclosure relates to a method for autonomous parking of a vehicle, and an automatic drive vehicle. The vehicle receives an input signal for parking the vehicle in parking premises (100) comprising a plurality of parking space (102) having an elevated parking boundary indicator (101). The vehicle (103) obtains a map of the parking premises (100). Further, the vehicle (103) receives a plurality of LIDAR data points (205) of the parking premises (100) and identifies a plurality of linear patterns from the plurality of LIDAR data points (205). Thereafter, the vehicle (103) detects atleast two linear patterns (401) from the plurality of linear patterns, having a predefined length and parallelly spaced apart, indicating the elevated parking boundary indicator (101) of an availableparking space, where the vehicle (103) can be autonomously parked in the available parking space.

Description

technical field [0001] The present invention relates to the field of autonomous vehicles (Autonomous Vehicles, AV). In particular, the invention relates to automatic parking of autonomous vehicles. Background technique [0002] Currently, many vehicles have self-parking features. In the prior art, automatic parking is assisted by cameras and ultrasonic sensors. In an existing computer-implemented system for determining preferred parking spaces for autonomous or semi-autonomous vehicles, cameras limit image clarity, especially at night, and thus cannot accurately determine parking spaces and parking boundaries. In addition, the system first preprocesses the 3D point cloud data collected by LIDAR (Light Detection and Ranging, LIDAR), and then calculates the minimum size of the parking space according to the vehicle dynamic theory. Secondly, according to the mobility characteristics of the autonomous vehicle, it improves the rapidly-exploring Random Tree (RRT) algorithm in t...
