Title:
METHOD FOR DETECTING ANGLED PARKING SPACE AND METHOD AND SYSTEM FOR AUTOMATIC PARKING
Document Type and Number:
WIPO Patent Application WO/2019/119944
Kind Code:
A1
Abstract:
A method and device for detecting an angled parking space, and a method and system for automatic parking, wherein the detection method comprises: determining a target angled parking space from among a plurality of angled parking spaces that are arranged along a reference line, wherein the target angled parking space is located between a first reference parking space and a second reference parking space (S11); detecting a first reference point that is used for identifying a point of intersection formed by the first reference parking space and the reference line (S12); calculating the slope of the target angled parking space (S13); detecting a second reference point that is used for identifying a point of intersection formed by the second reference parking space and the reference line (S14); calculating the width of the target angled parking space (S15). According to the described method, under the premise of fixing the installation position of an ultrasonic radar, an angled parking space that has a variable angle and that meets parking conditions may be automatically searched for, thus solving the deficiency of former automatic parking systems only being able to carry out automatic parking in parallel parking spaces and perpendicular parking spaces.
