Embodiment Construction

[0104] Embodiments of the present invention will be described with reference to the drawings.

[0105] Before describing the present invention in detail, the main points of the method and device for image-based hyperrealistic three-dimensional face modeling according to the present invention are described, that is, facial feature detection, facial model fitting, texture generation and use of stereoscopic images 3D reconstruction.

[0106] The modeling device according to the invention generates a hyperrealistic three-dimensional polynomial face model using images of two or three faces, which may be two images of the front and side, or three images of the front, near the front and the side image.

[0107] The image acquisition conditions are simple: good contrast and sharpness and sufficient lighting in the face area.

[0108] figure 1 is a flow chart of the image-based hyperrealistic three-dimensional face modeling method according to the present invention. figure 2 The d...

Abstract

An apparatus and method for image-based three-dimensional hyperrealistic head modeling are provided. The method used to create a three-dimensional hyperrealistic head model includes: detecting frontal and side features in the input frontal and side images; generating a three-dimensional head model by fitting a three-dimensional universal model using the detected facial features; according to the input generating realistic textures from front and side images; and mapping said textures onto a 3D head model. In the described apparatus and method, data obtained using relatively inexpensive equipment such as digital cameras can be processed in an automated manner, and satisfactory results can be obtained even from imperfect input data. In other words, facial features can be extracted in an automated manner and using stable "human quality" facial analysis algorithms.

Description

technical field [0001] The present invention relates to image processing, in particular to a method and device for image-based hyperrealistic three-dimensional face modeling. Background technique [0002] In the field of computer graphics, automatic hyperrealistic three-dimensional face modeling is considered a very important work due to its wide application in various fields such as virtual space creation, computer games, video conferencing and cartoon production . [0003] Although laser scanners for capturing precise 3D images from complex objects and ranging devices using structured light are commonly used, they are expensive and not easy to use. Computer-aided active interfacial modeling techniques require expert guidance and painstaking work. Consequently, intensive work has been devoted to allowing ordinary PC users to more easily reconstruct more realistic face models. In other words, there is a need to develop an algorithm, easily controlled by the average PC use...
