Title
(EN) Systems and Methods for Electric Vehicle Charging Using Image Capturing Devices
Abstract
(EN)

A plug connection system that autonomously charges an electric vehicle (EV) is provided. The method includes: adjusting configuration settings of an image capturing device; capturing an image using the image capturing device, wherein a portion of the image comprises an optically distinctive object associated with a charging portal of the EV, and wherein the image comprises a plurality of pixels; applying a pixel value threshold associated with a pixel metric to the image to filter the plurality of pixels of the image to a first subset of pixels; determining, based on filtering the plurality of pixels to the first subset of pixels, a location of the optically distinctive object associated with the charging portal of the EV within the image; and providing information to maneuver a robotic arm to a physical position associated with the location of the optically distinctive object within the image.
