Problems solved by technology

In other words, different individuals may have very similar face or head shapes, but their hairstyles have their own characteristics and personalities, and the differences shown are difficult to reflect through simple modeling methods
[0005] Therefore, it can be seen that in the prior art, 3D hair modeling cannot be effectively automated based on images captured by common camera devices

Abstract

The invention provides a device and method for modeling 3D (three-dimensional) hair based on a 3D hair template. The device comprises a 3D hair template library and a 3D hair model generation unit, wherein the 3D hair template library is used for storing one or more 3D hair templates in advance; the 3D hair model generation unit is used for receiving a front elevation hair image and a 3D head model; and a real 3D hair model is generated by processing one or more 3D hair templates provided by the 3D hair template library based on the characteristics of the front elevation hair image in combination with the 3D head model.

Description

technical field [0001] The present invention relates to three-dimensional (3D) hair modeling technology, and in particular, to an efficient apparatus and method capable of automatically performing 3D hair modeling, wherein, using an avatar captured by a simple photographing device (eg, a common camera), 3D hair modeling based on 3D hair templates. Background technique [0002] Human hair (ie, hairstyle) is a very important part in non-realistic rendering, character portraiture, and digital character animation, and the creation of hair significantly enhances the realism of virtual characters in avatars and entertainment applications. Therefore, hair modeling for 3D characters is a key problem in the fields of 3D computer graphics and computer vision. This technology allows the reproduction of real hair appearance in a virtual / augmented reality environment. [0003] In the field of 3D computer graphics, 3D modeling refers to the process of producing an arithmetic representat...
