Estimation method for dressed body 3D model in single character image

Abstract

The invention discloses an estimation method for a dressed body 3D model in single character image. The method comprises the steps of firstly, establishing a 3D model training sample based on a real character, secondarily, studying a varied function between a human body posture, a figure and clothes on the training sample, and calculating an average figure of various real character figures, then selecting a single image containing a dressed body image, enabling a user to select a clothes type and the positions of a plurality of joints, enabling a computer to initialize a three-dimensional posture of the dressed body image according to the positions of the joints and provide the clothes type selected by the user and the average figure for the three-dimensional posture so as to obtain an initial three-dimensional model of the body image, and lastly automatically adjusting the figure and posture of an initialized three-dimensional model according to the outline of the dressed body image to enable the three-dimensional model to conform with the shape of a targeted character. The estimation method for the dressed body 3D model in the single character image only need the single character image to establish the three-dimensional dressed character model and is wide in application range and simple and convenient to operate.

Description

technical field [0001] The invention relates to the fields of human body modeling and computer-aided design, in particular to a method for estimating a three-dimensional model of a dressed human body in a single character image. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) takes computer technology as the core and combines relevant science and technology to generate a digital environment that is highly similar to a certain range of real environments in terms of sight, hearing, and touch. Objects interact and influence each other, which can produce the feeling and experience of being in the corresponding real environment. With the continuous development of social productivity and science and technology, the demand for virtual reality technology in various industries is increasingly strong, people pay more and more attention to the research of virtual reality technology, virtual reality technology has also made great progress, and graduall...

Problems solved by technology

[0012] By analyzing the research status at home and abroad, it can be concluded that the current research on estimating the 3D model of the target person based on image / video is still in its infancy, and most of the research needs to build a collaborative multi-view environment; there are few methods for estimating the person model for a single image , and the clothing requirements of the target person are strict, it is difficult to put it into practical use and meet the needs of the majority of users
