Title:
METHOD FOR DETERMINING POSITION OF BATTERY BOX AND METHOD FOR DISASSEMBLING AND REPLACING BATTERY BOX
Document Type and Number:
WIPO Patent Application WO/2023/060511
Kind Code:
A1
Abstract:
A method for determining the position of a battery box, comprising: obtaining a positioning model of each of m cameras of a battery swapping station (102); setting a weighted sum of the positioning models of the m cameras as a location estimation model (104); obtaining object coordinates of n reference points in the battery swapping station (106); solving m weight coefficients of the location estimation model according to the object coordinates and predicted object coordinates based on the location estimation model (108); obtaining camera coordinates of a feature point of a battery box of a vehicle in the m cameras (110); and substituting the camera coordinates into the location estimation model to determine the location and posture of the battery box (112). Also provided are a method for disassembling and replacing a battery box and a non-volatile storage medium.
