Abstract
The present disclosure relates to an image processing method for a multi-dimensional region of interest (ROI) in a wireless charging system. More specifically, the method includes determining whether a surveillance target exists in the multi-dimensional ROI by performing, regarding the surveillance target, the process of removing a false-alarm region and including an excluded ROI.
Claims20
An image processing method performed by a computing apparatus, the method comprising:
- collecting, from a camera working with the computing apparatus, a plane image of a charging space to be monitored according to a surveillance angle of the camera;
- setting a multi-dimensional region of interest (ROI) on the collected plane image of the charging space for determining whether there is a surveillance target;
- when there is a surveillance target in the multi-dimensional ROI, determining a distance between the camera and the surveillance target on the plane image and an angle between a straight line from the camera onto the plane image and the surveillance target;
- and
- determining a surveillance target in the plane image by determining rectangular coordinates of the surveillance target on the plane image based on the distance and the angle.
A computing apparatus performing an image processing method, the computing apparatus comprising:
- a processor configured to collect, from a camera working with the computing apparatus, a plane image of a charging space to be monitored according to a surveillance angle of the camera, set a multi-dimensional region of interest (ROI) on the collected plane image of the charging space for determining whether there is a surveillance target, when there is a surveillance target in the multi-dimensional ROI, determine a distance between the camera and the surveillance target on the plane image and an angle between a straight line from the camera onto the plane image and the surveillance target, and determine a surveillance target in the plane image by determining rectangular coordinates of the surveillance target on the plane image based on the distance and the angle.
A wireless charging system comprising:
- a computing apparatus configured to set an image-processing based multi-dimensional region of interest (ROI) based on a multi-dimensionality of a charging region that a foreign object may invade, and handle the set multi-dimensional ROI on a plane image;
- and
- a camera that works with the computing apparatus and of which a surveillance range of the multi-dimensional ROI changes according to a surveillance angle,
- wherein the computing apparatus is configured to determine a presence or absence of a surveillance target in the multi-dimensional ROI and, according to the presence and absence of the surveillance target, determine a location of the surveillance target on the plane image.
