Three-dimensional face modeling method and device

Abstract

The invention provides a three-dimensional face modeling method to achieve efficient three-dimensional face modeling. The method includes the steps that an original image and a standard model are obtained; the bone point information is obtained according to the standard model; a feature point is marked on the original portrait and the coordinate information of the feature point is recorded; first conversion is conducted on the original portrait; second conversion is conducted on the standard model; the surface of the standard model generated after the second conversion is conducted is unfolded according to the preset method to form a texture image; the original portrait generated after the first conversion is conducted is mapped to the texture image. The invention further provides a corresponding three-dimensional face modeling device for implementing the three-dimensional face modeling method. According to the technical scheme, the three-dimensional face modeling method and device are simple in operation mode, good in fitting effect and high in degree of reduction; meanwhile, the method and device are higher in implementation speed and higher in efficiency, the processes of implementation and calculation are simplified, the data collection process is simplified, practicability and adaptability of a system are improved, and the method and device have great advantages in situations of low requirement for the face depth information.

Problems solved by technology

However, although the method of using multiple face images for modeling can obtain the information such as the frontal texture and face depth of the face relatively completely, it increases the steps of manual operation to a certain extent and reduces the flexibility of the operation.

And on some handheld devices, it is difficult for users to provide side images that meet the requirements more conveniently, which also has a great impact on the accuracy of face modeling
