Image processing device and method of locating a display device in an image

Abstract

Embodiments of the present application provide an image processing device and a method for positioning a display device in an image, and relate to the technical field of image processing. The image processing device comprises a controller configured to: identify a display device in a to-be-processed image, and obtain a detection box of a target display device in the to-be-processed image; extract an image region including each edge of the target display device according to the detection box of the target display device; obtain a minimum circumscribed rectangle of each edge of the target display device according to the image region including each edge of the target display device; obtain a straight line equation of each edge of the target display device according to the minimum circumscribed rectangle of each edge of the target display device; and obtain position coordinates of each corner point of the target display device in the to-be-processed image according to the straight line equation of each edge of the target display device. The embodiments of the present application are used for accurately positioning a display device in an image.
