Abstract

The embodiment of the invention provides a method and device for implanting planar pattern advertisements into a video frame. The method comprises the steps that coordinates of first pixel points in target images, comprising a plane object, of a target video are determined, and the first pixel points in the target images can locate a region, into which the planar pattern advertisements are to be implanted, on the plane object; coordinates of second pixel points in an advertisement image are determined, the second pixel points can locate a region where the planar pattern advertisements are located, the number of the first pixel points in each frame of target images is the same as that of the second pixel points, and the first pixel points in each frame correspond to the second pixel points one to one; the coordinates of the first pixel points and the coordinates of the second pixel points in the target images are utilized for calculating a perspective change matrix of each frame of target images; the perspective change matrixes and the advertisement image are utilized for carrying out perspective change processing on the pixel points in the region, into which the planar pattern advertisements are to be implanted, in each frame of target images. According to the method and the device, the planar pattern advertisements can be implanted into the video frame of the photographed video.

Description

technical field [0001] The invention relates to the field of technical video processing, in particular to a method and device for embedding plane pattern advertisements in video images. Background technique [0002] Product placement is increasingly used in movies and TV dramas, and for the placement of graphic advertising, usually the graphic advertising is placed in the shooting environment, and then the graphic advertising appears in the lens, thereby generating Videos with graphic ads in the video frame. [0003] In some cases, there is no need to insert flat pattern advertisements during the video shooting process, but in the subsequent video distribution process, there will be a need to insert some flat pattern advertisements, that is, there are video screens The demand for embedding graphic advertisements in [0004] On the premise of ensuring the user's visual experience, how to embed a graphic advertisement in the video screen of the completed video is an urgent p...
