Title:
PARKING SPACE DETECTION METHOD AND APPARATUS, AND MEDIUM AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/007235
Kind Code:
A1
Abstract:
Disclosed are a parking space detection method and apparatus, and a medium and a device. The method comprises: respectively performing clustering and piecewise fitting on points on an obstacle detected by ultrasonic radars at left and right sides of a vehicle, so as to obtain a set of obstacle line segments (l1, l2, l3) respectively corresponding to the left and right sides of the vehicle, and endowing the line segments with high and low attributes; and by means of a model matching method, determining whether there is a parking space between two adjacent line segments (l1, l2) with the high attribute. Both a driving path and a direction of a vehicle are not limited, thereby improving the universality of parking space detection.
