Mapping method, device, terminal device and storage medium for two-dimensional template image

Abstract

The present application relates to a mapping method, apparatus, terminal device and storage medium for a two-dimensional template image. The method includes: detecting an image to be mapped, and acquiring a plurality of first key points; according to the plurality of first key points, a plurality of second grids corresponding to two-dimensional template images in a preset template library, and a preset association relationship , determine a plurality of first grids corresponding to the to-be-mapped image; according to the association relationship, fill the pixels in each second grid into the corresponding first grid, so as to be in the to-be-mapped image The surface redraws the two-dimensional template image. The method enables the shape and position of the two-dimensional template image to follow the deformation of the to-be-mapped image to generate corresponding deformation during display performance, thereby greatly improving the matching degree between the two-dimensional template image and the deformed to-be-mapped image , which further improves the intelligence of human-computer interaction.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a mapping method, apparatus, terminal device and storage medium for a two-dimensional template image. Background technique [0002] With the development of image processing technology, people have higher and higher requirements for processing face images. In daily life, people often add face stickers to the photographed face images or perform partial display processing on the face images, so as to improve the display effect. For example, add a facebook sticker to the area of ​​the captured face. [0003] Usually, we add stickers to the face image or perform partial display processing on the face image, for example, adding a mask to the face image to display the face image with the mask, and making the lips redder or eyebrows. To display images with beautifying effects such as darker, the corresponding stickers are displayed in the corresponding area of ​...

[0004] However, the face image displayed by the above method deforms on the face. For example, when adding a Facebook sticker on the face image, the person opens his mouth, but the face still stays in the state of not opening his mouth, which may appear The case where the face masks the mouth, thus causing a mismatch between the sticker and the deformed face area
