Research And Implementation Of 3D Human Modeling Through Head And Body Treated Separately

Three-dimensional human body model is widely used in animation, video etc. How to achieve high- fidelity three-dimensional modeling of the human, is an issue industry and academia common concern.This paper uses two modeling methods, the scanning data modeling method and parametric modeling method. It makes full use of the advantages of both modeling methods to study the modeling of three-dimensional human body with personalized head. We study the key issues of the problem.This work has two main aspects:(1) Using multiple RGB-Depth Camera to create three-dimensional head model. We use the new RGB-Depth Camera-- Xtion Pro Live, construct multicast RGB-Depth camera scanning system to scan the head of target. By analyzing the parameters of the camera, we propose a configuration model with multiple RGB-Depth cameras. The model considers a range of viewing angles, the error accuracy and other parameters of the camera, to ensure that multi-camera can effectively cover the head. For this system, within a second to complete the full range of data collection on the head, we complete the surface reconstruction of the point cloud data, to generate high- fidelity three-dimensional head model.(2) Parametric modeling of the three-dimensional human body with personalized head. We use the human parametric equation for human modeling. By specifying the human body geometry features(such as gender, height, weight, etc.), we create the complete three-dimensional human body models. This article uses data adhesive technology, bonds the head and body perfectly, and gets a complete three-dimensional human model with personalized head.The experimental results show that this method can create a complete three-dimensional human model with personalized head, which has a high fidelity, can be used to apply animation and video aspects.
