The embodiment of the invention provides a three-dimensional face model reconstruction method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an image pair of a target face in n view angle directions, the image pair comprising a color image and a depth image; determining a target color image aligned with the depth image according to the color image and the depth image in the image pair for the image pair of the target human face in any visual angle direction; inputting the target color image into a pre-trained recognition model, so that the recognition model outputs a face mask matrix corresponding to the target color image; processing the depth image by using the human face mask matrix to obtain a target depth image, and converting the target depth image into a human face point cloud of a target human face in a visual angle direction; and according to the face point clouds of the target face in the n view angle directions, determining the target face point clouds, and performing curved surface reconstruction on the target face point clouds to obtain a three-dimensional face model.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of computer vision of artificial intelligence, and in particular to a method, device, electronic device and storage medium for reconstructing a three-dimensional face model. Background technique [0002] At present, 3D face model reconstruction based on real faces has broad application scenarios in many fields such as face recognition systems, medicine, film advertisements, computer animation, games, video conferencing, video telephony, and human-computer interaction. in face recognition. [0003] At present, there are mainly two ways to reconstruct the 3D face model: Method 1, build a monocular camera array, and use the parallax principle to realize the reconstruction of the 3D face model; Method 2, use laser scanning equipment to use the principle of laser ranging Realize 3D face model reconstruction. [0004] Since the original point cloud can be obtained through a monocular camera...
