Multi-angle and multi-background image fusion method and device and medium

Abstract

The embodiment of the invention discloses a multi-angle multi-background image fusion method and device and a computer readable medium. The multi-angle multi-background image fusion method comprises the following steps: acquiring a to-be-fused card image marked with coordinates of each vertex; and according to the coordinates of the vertexes, constructing a contour map of the card to be fused on the pure color background map; obtaining a target vertex coordinate from a pre-established image library; calculating a target perspective transformation matrix according to each vertex coordinate andthe target vertex coordinate of the card to be fused; and carrying out perspective transformation on the to-be-fused card image and the contour map by using the target perspective transformation matrix to obtain a target card image and a target contour map after angle transformation; and according to the target contour map, filling a preset background plate with the target card image to realize fusion of the to-be-fused card and the background plate. According to the technical scheme, only one card image and a plurality of different background plates are needed, and the images of the card at different angles of the different background plates can be rapidly obtained.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-angle and multi-background image fusion method, device and computer-readable medium. Background technique [0002] A card image refers to a flat image of an item with a regular border, for example, an ID card image, a bank card image, and the like. According to the requirements of the application scenario, it is often necessary to obtain the image information of the card in different backgrounds, and the image information of the card in different angles under the same background. [0003] In the traditional way, it is necessary to obtain the required images by manual shooting. For example, when it is necessary to obtain images of cards in different backgrounds, it is necessary to manually place the cards under different background plates, so as to manually photograph the cards in different backgrounds one by one. image below. When it is necessary to obt...
