摘要/Abstract

摘要： 提出了一种使用单台Kinect体感探测设备生成实时的人体试衣模型的方法。利用廉价设备进行实时的三维人体模型试衣具有非常高的应用价值,但是目前的人体三维扫描技术大多数尚无法达到实时的人体模型虚拟穿衣。在穿衣之前需要通过Kinect生成实时人体模型。采用了基于人体胖瘦信息的实时人体模型重建方法,并对其方法进行优化增强其局部仿真效果。针对布料动画计算量巨大的问题,设计了一种椭球跟踪模型,从而在保证布料动态真实性的前提下减少了计算量。同时,在程序开发中,使用了GPU并行计算来处理布料动画计算,有效减少了单次步长的计算时间,提高了程序的实时性。

关键词: 特征圈, 虚拟试衣, 并行计算, 布料动画, 碰撞检测

Abstract: In this paper we put forward a real-time method of virtual dressing using a single Kinect device. Virtual dressing using a low-cost device has very important application, but classic 3D human body dressing algorithms cannot work in real time. We need to generate 3D human body model before virtual dressing using Kinect. In this paper, we use a method which is based on body's basic information to build human body model, and the method is optimized to enhance the local simulation results.This paper presents a tracking ellipsoid modeland applies GPU parallel computing to decrease the amount of calculation of cloth animation,which effectively reduces the computation time of single step and improves the real-time performance of the program.

Key words: character circle, virtual dressing, parallel computing, cloth animation, collision detection
