Abstract

The invention provides a three-dimensional model generation method and device. The method comprises the following steps: acquiring a first image comprising a first human face; determining first pointcloud data including contour information of a first face based on the first image; determining first reflectivity information of the first face and second point cloud data including detail informationof the first face based on the first point cloud data and the first image; and generating a three-dimensional model of the first face based on the first reflectivity information and the second pointcloud data. According to an embodiment of the invention, the obtained three-dimensional model of the first face not only comprises the reflectivity information of the first face, but also comprises the contour information and detail information of the first face, so the generated three-dimensional model of the first face has higher trueness.

Description

technical field [0001] The present disclosure relates to the technical field of three-dimensional reconstruction, and in particular, to a three-dimensional model generation method, device, computer equipment, and storage medium. Background technique [0002] The generation of digital 3D face models plays an important role in the fields of film and television, games, and virtual social interaction. The method of face generation (reconstruction) based on a single image has great application value because data collection only relies on cheap network cameras and is convenient for mobile applications. [0003] The current method for generating a three-dimensional face model has the problem of low accuracy of the generated three-dimensional face model. Contents of the invention [0004] Embodiments of the present disclosure at least provide a three-dimensional model generation method, device, computer equipment, and storage medium. [0005] In a first aspect, an embodiment of ...
