Document Type and Number:

WIPO Patent Application WO/2020/253010

Kind Code:

A1

Abstract:

A method and apparatus for positioning a parking entrance in parking positioning, and a vehicle-mounted terminal. The method comprises: when it is detected that a vehicle enters an entrance of a parking lot, and it is determined that the location indicated by an initial vehicle posture of a positioning module is within a preset initialized identification region, obtaining a parking lot image collected by a camera module (S120); detecting semantic information of the parking lot image (S130); determining a first vehicle posture of the vehicle by means of a posture regression model based on the semantic information of the parking lot image and the initial vehicle posture (S140); and matching the semantic information of the parking lot image with semantic information of each location point in a preset map according to the first vehicle posture, and determining a second vehicle posture of the vehicle according to the matching result (S150), wherein the posture regression model is obtained by training according to a plurality of sample parking lot images collected in the initialized identification region in advance. The method can improve the positioning accuracy at the entrance of the parking lot.
