Embodiment Construction

[0021] In order to make the purpose, features, and effects of the present application easier to understand, examples and drawings for explaining the present application in detail are provided below.

[0022] figure 1 For a schematic block diagram of an embodiment of an apparatus according to the present application, see figure 1 As shown, the device 10 for establishing a 3D face model includes a 3D image capture device 12 and a computing device 14 . The three-dimensional image capturing device 12 is corresponding to the human face of the subject to capture at least one corresponding human face image. The computing device 14 is electrically connected to the 3D image capture device 12 to receive the face image, and perform subsequent calculation and application according to the face image. In one embodiment, the 3D image capturing device 12 and the computing device 14 can be independent devices, for example, the 3D image capturing device 12 is a 3D infrared camera, and the com...

Abstract

The invention provides a method and equipment for establishing a three-dimensional face model. The method includes: acquiring front face information of a user in a first time interval to establish a three-dimensional front face model and generate a front face planar graph image corresponding to the three-dimensional front face model, the front face planar graph image including a plurality of first feature points; obtaining full face information of the user in a second time interval to establish a three-dimensional full face model and generate a full face planar graph image corresponding to the three-dimensional full face model, the three-dimensional full face model having a specific part and the full face planar graph image including a plurality of second feature points; according to the corresponding relation between the first feature point and the second feature point, overlapping a first block, corresponding to the specific part of the three-dimensional full face model, in the front face planar graph image to a second block, corresponding to the specific part of the three-dimensional full face model, in the full face planar graph image, so as to obtain a complete full face planar graph image; and generating a three-dimensional face model according to the complete full face planar graph image.

Description

technical field [0001] The present application relates to a method and equipment for establishing a three-dimensional human face model. Background technique [0002] The 3D face model is constructed based on the 2D face image, and in the process of capturing the 2D face image, a positioning bracket is used to fix the user's head to increase the accuracy of the captured image Spend. [0003] However, if the positioning bracket is used to capture the face image, since the positioning bracket will cover the face of the user, there will be a covered area in the scanned two-dimensional face image, making the established three-dimensional face model incomplete , reducing the quality of the acquired image, and also affecting the application of the 3D face model in orthodontics or chin beauty. Contents of the invention [0004] In view of this, the present application provides a method for establishing a 3D face model, including: obtaining a user's frontal face information withi...
