Method for building clothing three-dimensional model based on single image

Abstract

The invention provides a method for building a clothing three-dimensional model based on a single image. The method mainly comprises the following steps that a human body three-dimensional model of an input image is estimated, and a clothing three-dimensional plane is built according to the clothing outline of the input image; the clothing three-dimensional plane is used, the human body three-dimensional model is combined, and a smooth clothing three-dimensional model is generated through a deformation algorithm; an intrinsic image decomposition algorithm and a shape-from-shading algorithm are used, the detail information of clothing is acquired from the input image, the acquired clothing detail information is transferred to the smooth clothing three-dimensional model through a Laplace editing algorithm with a weight, and the final clothing three-dimensional model is obtained. According to the method for building the clothing three-dimensional model based on the single image, only one single image is used, the clothing three-dimensional model with surface geometric details such as folds and wrinkles can be generated, and the defects of an existing method in the aspects of multi-view model building environment setting and realistic surface geometric detail acquiring are overcome.

Description

technical field [0001] The invention relates to the technical fields of computer graphics, computer vision and virtual reality, in particular to a method for constructing a three-dimensional clothing model based on a single image. Background technique [0002] Image-based 3D model construction of scene objects is an important part of virtual reality and virtual scene generation, especially the construction of 3D model of scene objects with non-rigid deformation such as clothing is a current international frontier research hotspot. The 3D model of clothing with strong sense of reality has wide application value. [0003] The traditional three-dimensional clothing model construction method refers to the real clothing design and cutting process, and obtains the final three-dimensional clothing model through the steps of two-dimensional pattern design, physical simulation and simulation, and iterative optimization of parameters with manual participation. Traditional clothing 3D...
