Abstract
A method for aligning a charging device with a vehicle for charging includes detecting whether a vehicle is parked on a parking space where the charging device is located. If so, capturing at least one image of the vehicle and determining a position of a power receiving device of the vehicle by reference to the at least one image. Controlling movement of the charging device based on the relative positions of the power receiving device and a position of the charging device and aligning the charging device to couple wirelessly and charging the vehicle.
Claims14
A charging device comprising:
- at least one processor;
- and
- a storage device coupled to the at least one processor and storing instructions for execution by the at least one processor to cause the at least one processor to:
- detect whether a vehicle is parked on a parking space where a charging device is located;
- capture, in response that the vehicle is detected to be parked on the parking space where the charging device is located, at least one image of the vehicle;
- determine a position of a power receiving device of the vehicle by recognizing the at least one image;
- determine a pixel coordinate of the vehicle in the image according to information as to body structure of the vehicle;
- convert the pixel coordinate of the vehicle to a camera coordinate;
- convert the camera coordinate of the vehicle to a world coordinate;
- determine a world coordinate of the power receiving device according to the world coordinate of the vehicle and information as to position of the power receiving device;
- and
- determine at least one movement parameter of the charging device according to deviation between an initial world coordinate of a power transmission device of the charging device and the world coordinate of the power receiving device;
- control the charging device to move until aligned with the power receiving device according to the at least one movement parameter;
- and
- control the charging device to couple with the power receiving device and to charge the vehicle.
