Embodiment Construction

[0040] The premise of the parametric modeling method is to measure an accurate model of the human body. However, as people pay more attention to personal privacy, it is not the best choice to require users to measure in a near-naked state. Therefore, in the case of people dressing, it will be a better choice to obtain an accurate 3D net model of the human body by performing undressing calculations on the dressing model, and further 3D fitting. The present invention will be described in further detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0041] 1. Method for establishing 3D net model of human body

[0042] A method for building a 3D net model of the human body, such as figure 1 As shown, the following steps are included: S1: establish a human body 3D net model database; S2: collect the depth image of the current human body in the situation of wearing clothes; S3: obtain the height, weight and gender information of th...

Abstract

The invention provides a pure 3D human model building method. The method comprises the following steps of S1, establishing a pure 3D human model database containing body height, body weight and gender information; S2, collecting a depth image of a current human body in a dressing condition; S3, obtaining the body height, body weight and gender information of the current human body; S4, extracting a pure sample model; and S5, obtaining a pure model of the current human body according to the pure sample model. According to the pure 3D human model building method, the influence of clothes and local characteristics such as the body height, the body weight, the gender and the like can be eliminated at the same time, and the pure model of the human body can be accurately obtained only by utilizing the depth image of the human body in the dressing condition. In addition, based on the pure 3D human model building method, the invention provides a 3D fitting method and a 3D fitting system. Whether the human body wears loose clothes or tight clothes, the dressing effect can be displayed at 360 degrees in real time by use of the 3D fitting method or system.

Description

technical field [0001] The invention relates to the fields of computer technology and image processing technology, in particular to a method for establishing a 3D net model of a human body using a depth image and its application in 3D fitting. Background technique [0002] The three-dimensional (3D in this article) model of the human body plays an important role in 3D printing, clothing customization, 3D fitting, and animation production. At present, there are two main ways to obtain the 3D model of the human body. One is through computer modeling. The model obtained in this way is smooth and realistic, but it has high requirements for the technical level of the modeler, and the modeling efficiency is also low; Another way is to directly measure the human body through equipment such as 3D scanners or depth cameras. Generally, point cloud data is obtained in this way, and a satisfactory human body model can be obtained through subsequent processing such as denoising and gridd...
