Dressed human body three-dimensional bare body model calculation method through single Kinect

Abstract

The invention discloses a dressed human body three-dimensional bare body model calculation method through one single Kinect. The method includes calibrating a Kinect camera, capturing a dressed human body RGB-D images and frame information, and extracting human body deep images before denoising; dividing the human body into multiple rigid parts, acquiring partial human body deep images by segmenting, acquiring a three-dimensional human body shape by registering and infusing, and acquiring a complete three-dimensional human body shape by matching and combining before denoising; acquiring a three-dimensional bare body sample model to construct matrix and reduce the dimensionality, and acquiring low-dimensional three-dimensional bare body sample matrix and mapping matrix; selecting a template model to be flushed with initial frame postures; fitting the template model to the three-dimensional human body shape through corresponded points to project to the low-dimensional matrix, multiplying by the mapping matrix, and acquiring a three-dimensional bare body module; repeating iterations until a final three-dimensional bare body model is acquired. By the aid of the method, the problem of excessive fitting of the dressed human body is solved, and a personalized three-dimensional bare body model can be calculated for the dressed human body rapidly, conveniently and economically through single Kinect equipment.

Description

technical field [0001] The invention relates to a method for calculating a human body model, in particular to a method for calculating a three-dimensional net body model for a dressed human body by using a single Kinect, which can conveniently calculate a real three-dimensional net body model for a dressed human body. Background technique [0002] Personalized 3D mannequins play a vital role in the field of virtual reality. Movie animation, 3D game design, virtual try-on and 3D clothing design are all closely related to personalized 3D mannequins. Therefore, there is an urgent need to quickly, economically and accurately construct personalized 3D human body models. The existing 3D human body model construction methods can be roughly divided into the following categories: geometric interaction methods, 3D scanning methods, depth image registration methods and methods using multiple Kinects to obtain depth images. Among them, the geometric interaction method is divided into t...
