Title: Capturing object deformations

Abstract
In this presentation, I will introduce 3D object capture tools: the stereo camera and 3D scanner; what method i use to tracking the object feature points when the object is deforming; how I use feature points tracking information to calculate the rigid object transformation matrix. Some technique will be mentioned in this presentation, there are KLT tracking algorithm, ICP(interative closest point) method and quaternion for orientation.  At the end of the presentation, I will introduce some future works，such as 3D model noise removing, local object deforming.
