Research And Realization Of Realistic Technique Of Individual 3D Mannequin

With the development of virtual reality technology in recent years,the virtual world imitated by computer become more and more real.Virtual human is an important part of virtual reality technology which has received wide attention.While experiencing the content and the reality of the scene,people also began to want to use a high-level sense of virtual characters as their avatar,to reflect their own personalities or characteristics.Therefore,this paper will take the research of the real-sense technology of the Individual 3D virtual human model as the research object and analyze the present situation and key technologies of individual 3D virtual human model to design a low cost,high efficiency,real-time and interactive adjusting system of 3D virtual human model.The body character is an important symbol of individuation.Firstly,the paper will adopt 3DMorphing technology to regulate the dress size of human model and realize the eight smooth adjustments of human body related parts such as height,arm length,waist circumference and bust.At the same time,we will realize a regulating function of smooth and continuous adjustment of skin color and smoothness of the human body model by adding skin impact factor and specular reflection parameters on the standard illumination model.Compared with the traditional model of individual virtual human models,this design is more low-cost and efficient that users can observe the stature and skin color changes in real time through adjusting the parameters.In some degree,although the adjustment of the stature and color of virtual human model enhances the sense of reality of the individual virtual human model,the sense of substitution is still lacking.There may be a lot of people around the world who are similar in stature and color,but few have similar looks.Thus,to further enhance the sense of reality,the paper will aim at the realistic head model,and propose a real face image fusion technique based on Gaussian-Laplacian pyramid algorithm and create a realistic skin of the head model by seamlessly splicing three photos on the front,right and left sides of the face,then realize the texture mapping of the model head by two-step projection texture mapping,and finally obtains a realistic head model.
