Problems solved by technology

However, using the two-dimensional structural information and depth information of the two-dimensional image to construct the three-dimensional face shape, while capturing the two-dimensional image, the depth information corresponding to the two-dimensional image is obtained, which has higher requirements on the capturing device of the human face image. , thus increasing the complexity of constructing 3D face shape, which also increases the complexity of 3D face reconstruction, which is not conducive to the widespread promotion of 3D face reconstruction

Abstract

Provided are an image processing method and device, the method comprising: acquiring a two-dimensional target facial image; receiving an identification curve marked by a user in the target facial image, the identification curve being used to indicate the contour of a face in the target facial image; based on the identification curve, positioning the facial contour curve of the face in the target facial image by utilizing an image segmentation technology; determining the three-dimensional attitude and feature point positions of the face in the target facial image; and according to the facial contour curve, three-dimensional posture and feature point positions of the face in the target facial image, constructing a three-dimensional shape of the face in the target facial image by utilizing a preset empirical model of the three-dimensional shape of the face and a target function matching the empirical model of the three-dimensional shape of the face. The method and device reduce the complexity in constructing a three-dimensional shape of the face.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically relates to an image processing method and device. Background technique [0002] Image-based 3D face reconstruction refers to building a 3D face model from a 2D image or video containing a face. 3D face reconstruction is a research hotspot in the field of computer vision research, and is widely used in biometric information authentication, computer games, teleconferencing systems and other fields. [0003] The 3D face reconstruction process needs to recover the 3D shape and texture of the face from the 2D image of the face, and then structure the 3D shape and texture of the face to construct a 3D face. In order to accurately construct a 3D face, in the process of constructing a 3D face shape, it is necessary to use a binocular camera to capture face images to obtain the 2D image and depth information of the face, and extract the 2D The two-dimensional str...
