Embodiment 2

[0077] Figure 2A It is a flow chart of a face mesh model reconstruction method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments. Specifically, refer to Figure 2A , this embodiment may include the following steps:

[0078] S210. Acquire the face scan data to be reconstructed and the three-dimensional face grid template.

[0079] S220. Acquire the original resolution of the 3D face grid template, and determine the grid precision of the 3D face grid template according to the original resolution.

[0080] Specifically, during the creation of the 3D face mesh template, the higher the pixel resolution of the selected model is, that is, the more grids are distributed in the 3D face mesh template, the designer needs to spend more energy and The cost is also higher, so when the face mesh model is reconstructed, the designer generally chooses a medium-precision 3D face mesh template to match the face scan dat...

Abstract

The invention discloses a face mesh model reconstruction method, a device, an appartus and a storage medium. The method comprises the following steps: acquiring face scanning data to be reconstructedand a three-dimensional face mesh template; The key feature points in the 3D face mesh template are extracted hierarchically, and the 3D face mesh template is deformed according to the posture matching positions of the key feature points extracted hierarchically in the face scanning data, and the target face mesh model is obtained. Obtain the global feature points of the target face mesh model, and according to the pose matching position of the global feature points in the face scanning data, the target face mesh model is deformed, and the reconstructed face mesh model is obtained. The technical proposal provided by the embodiment of the invention solves the problem that the reconstruction speed of the human face mesh model in the prior art is slow and the smoothness is poor, improves thereconstruction speed and the reconstruction effect of the human face mesh model, and improves the smoothness of the reconstructed human face mesh model.

Description

technical field [0001] The embodiments of the present invention relate to the field of image processing, and in particular to a reconstruction method, device, device and storage medium of a mesh model of a face. Background technique [0002] With the development of video technology, there is an increasing demand for the creation of realistic face models in entertainment applications that require face display. At present, creating a realistic 3D face model is a very difficult task. If it is completely built by hand, it will consume a lot of manpower and material resources. In the game and film industries, the use of 3D scanning technology to obtain realistic human faces has become the mainstream. As the price of 3D scanning hardware decreases, this technology will become more and more popular. However, when we need to create a series of realistic faces in batches, due to the common noise and defects in the scanned data obtained by using 3D scanning technology, and the mesh m...
