Abstract
A visual positioning method and system for a battery replacement device. The method comprises: controlling a battery replacement device to move below a battery accommodating portion at the bottom of an electric vehicle; photographing, by means of a photographing apparatus, a first target photographing region at a first focal length so as to obtain a positioning determination photograph; controlling the photographing apparatus to adjust the first focal length to a second focal length; and photographing, by means of the photographing apparatus, a second target photographing region at the second focal length so as to obtain a lock-state determination photograph. By means of the photographed photographs at different focal lengths, automatic adjustment of positioning, locking and unlocking is realized, not only achieving efficient and accurate determination of positioning, locking and unlocking of the battery replacement device, but also enabling the battery replacement device to achieve integral and efficient adjustment.
