Visual auxiliary positioning method and device for hoisting and battery replacement of new energy commercial vehicle

Abstract

The invention provides a new energy commercial vehicle hoisting battery replacement visual auxiliary positioning method and device, and the method comprises the following steps: driving a vehicle position collection camera to move through an X-axis movement assembly on a vehicle hoisting battery replacement station, and when the vehicle position collection camera moves to the midpoint position of the vehicle hoisting battery replacement station, carrying out the positioning of the vehicle position collection camera; the position of the new energy automobile is photographed through the automobile position collection camera, a first image of the automobile is collected and recorded into the terminal system, meanwhile, the first image of the automobile is compared with a pre-recorded automobile model in the terminal system so as to determine the first pose of the automobile, and the error of the parking pose of the automobile is calculated. According to the invention, accurate positioning of the moving position and the parking position of the vehicle is realized, the first pose and the second pose are collected, accurate disassembly and assembly of the battery pack of the new energy vehicle are facilitated, and the success rate and the positioning accuracy of visual positioning are improved.

Description

technical field

[0001] The present invention relates to the technical field of visual positioning, in particular to a method and a device for visual aided positioning of a new energy commercial vehicle for hoisting and replacing a battery. Background technique

[0002] When replacing the battery of the current new energy vehicles, most of the personnel manually replace the battery, which not only causes a large workload for the personnel, but also makes it difficult for personnel to replace the battery pack due to the large size and weight of the battery pack. The battery pack is disassembled from top to bottom, which also results in high danger for personnel during the disassembly process and low disassembly efficiency. SUMMARY OF THE INVENTION

[0003] The present invention aims to provide a visual aided positioning method and device for hoisting and replacing a battery of a new energy commercial vehicle to overcome the above problems or at least partially solve the abov...
