The invention discloses a face image processing method, which comprises the following steps that: electronic equipment acquires a two-dimensional image to be processed, constructs a three-dimensionalgrid model corresponding to the two-dimensional image to be processed according to a preset reference grid, and acquires a texture map of the three-dimensional grid model according to the shooting parameters of a two-dimensional image to be processed, determining boundary points and control points corresponding to the boundary points according to the visible boundary of the face of a reference grid; and the electronic equipment performs deformation processing on the three-dimensional grid model according to a preset deformation requirement in combination with the corresponding relationship between the boundary points and the control points, renders the texture image to the deformed three-dimensional grid model, and generates a processed image according to the rendered three-dimensional grid model. Through the control points and the boundary points of the three-dimensional grid model, the three-dimensional grid model is quickly adjusted, so that the image processing efficiency is improved, and the realization of high-quality real-time image processing is facilitated.
Description
technical field [0001] The present application belongs to the field of image processing, and in particular relates to a face image processing method and electronic equipment. Background technique [0002] With the development of camera technology, camera functions are more and more widely used in smart devices, such as smart phones, tablet computers and notebook computers. Through the camera function, it is convenient for users to collect images, including taking photos or videos, etc., making smart devices more popular with users. [0003] When using the camera function of a smart device, since the camera device of a smart device is generally set in an area outside the screen, when the user looks at the screen, the posture of the face in the image captured by the camera device will be tilted, and it is necessary to analyze the person in the image. Face posture correction. The current deformation fusion method based on 3D face reconstruction takes a long time to generate a...
