The Human Modeling Process And Implementation Based On The Features Points

3D Human Body Modeling has always been a hot research by scholars at home and abroad. Different applications field require different human model. It is focus and key for the study to how to quickly create a personalized human model.According to the above problems, this thesis analyzes the composition of human body surface model. The current methods of three-dimensional human body model are wireframe model, surface model, solid model, physical model and so on. This thesis uses the surface model. In the thesis, the 3D general human model is obtained by the DAZ 3D software that comes with the standard body, and saved as the OBJ file format that access to the human feature data.In this thesis, by using the characteristics of OBJ file format, the general 3D human body model of the surface mark with the triangle primitives. In the general 3D human body model feature points of extraction, according to the distinguish character of the grouping of human body parts, we extract some feature points that can change the human body shape. Using these feature points, we calculated the human body shape of feature size. According to the pronasale and the division of face region, we extract some facial feature points. In the general 3D human body shape modeling process, to avoid the deformated crack by directly using the OBJ file of the group for the human body surface, we redistribute the human body parts data by the extracted feature points. According to the ratio between the measurements of a human's three lines and the height, we achieve the human body shape change with the FFD local algorithm. In the general 3D human face personalized process, according to the facial feature points and the ratio between the each parts of human face, we realize the personalized facial with the overall transformation and local transformation algorithm. Finally, by the facial and body shape of transformation we implemet the individual human body modeling.Undoubtedly, this modeling method is low cost, easy, and rapid and so on by experiments. At the same time, the user can rotate the model and observe it from the different angle and distance. In the practical application, it has refernce values.
