Figure expression editing method and device, computer storage medium and terminal

Abstract

The invention provides a figure expression editing method and device, a computer storage medium and a terminal. The figure expression editing method comprises the steps: acquiring a face model in a three-dimensional grid, carrying out weak perspective projection on the face model, obtaining a perspective projection on a two-dimensional plane, wherein the perspective projection comprises two-dimensional face feature point positions and two-dimensional anchor point positions corresponding to the two-dimensional face feature point positions; obtaining a two-dimensional adjustment instruction foradjusting the positions of the two-dimensional anchor points, and adjusting the positions of the two-dimensional face feature points according to the two-dimensional adjustment instruction to obtain adjusted perspective projection and two-dimensional displacement of the corresponding two-dimensional anchor points; mapping the adjusted perspective projection and two-dimensional displacement to a face model to obtain a changed face model; and obtaining a three-dimensional adjustment instruction for adjusting the changed face model, and adjusting the changed face model according to the three-dimensional adjustment instruction to obtain a three-dimensional target expression. By means of the character expression editing method, more real and natural three-dimensional target expressions can be obtained.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, the present invention relates to a character expression editing method, device, storage medium and terminal. Background technique [0002] With the popularity of image acquisition equipment, it is becoming easier and easier to obtain digital face images, and people are more and more fond of various interesting and funny face images. It is the most interesting and challenging task to process and transform the human face in a portrait picture, animate the character's face and generate various expressions. There are many ways to drive facial expressions. You can use the expression of a real actor to directly drive the characters in the picture, or you can prefabricate the parameter sequence to play back the expression animation, but the expressions generated by these methods are not realistic and vivid enough. Therefore, how to generate natural and vivid human facial expres...
