Abstract

The embodiment of the present invention discloses a multi-angle and multi-background image fusion method, device and computer-readable medium, which acquires the image of the card to be fused marked with the coordinates of each vertex; and constructs the card to be fused on the solid-color background image according to the coordinates of each vertex outline drawing. Obtain the target vertex coordinates from the pre-established image library; calculate the target perspective transformation matrix according to the vertex coordinates of the cards to be fused and the target vertex coordinates; use the target perspective transformation matrix to perform perspective transformation on the image of the card to be fused and the outline map to obtain the angle Transformed target card image and target outline map. According to the target outline map, the image of the target card can be filled into the preset background board, so as to realize the fusion of the card to be fused and the background board. According to the technical solution, only one card image and a plurality of different background boards are needed, and the images of the card under different angles of different background boards can be quickly 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...
