摘要计算机的三维场景重建的目的是将生活中的物体数字化，以三维数字信息的方式展示出来。我们可以利用kinect体感摄像机作为输入设备，通过kinect采集的物体的深度图像以及彩色图像对物体进行三维场景的重建。Kinect采用的三维重建方法是基于结构光编码的方法，运用Light Coding技术。65157

本文在老师的帮助下以及查阅大量的中外文献，对人机交互技术、三维场景的重建方法、以及深度信息的获取方法等做了详细的介绍。而且用大量的篇幅介绍了kinect的工作原理和其关键技术——Light Coding技术。

利用本文的三维重建方法，用户不需要昂贵的精密设备，也不需要非常专业的操作，就可以利用kinect对物体进行简单的三维重建，从而感受到三维重建的乐趣。由于设备的精密度有限的原因，我们最后获得的三维模型不是完全完美的，可是能够大体上满足日常生活娱乐的需求。

Title       Research of 3D Reconstruction Based On Microsoft Xbox Kinect Sensor                                                

Abstract The purpose of computer 3D reconstruction is to digitalize the things in our life and display them in the way of 3D digital information . We can use kinect as output device to reconstruct 3D scene by the depth image and color image which kinect collects. Based on structured light coding, kinect uses Light Coding as the method of 3D reconstruction.

This article makes a particular introduction to Human-Computer Interaction，the method of 3D reconstruction and the way to acquire depth information by the help of my teacher and reading lots of papers. What’s more, lots of information about the operating principles of kinect and its key technology—Light Coding.

By using the method which is introduced in this article, without the need of gaining expensive equipment and professional operating, users can still rebuild objects in 3D scene by kinect, which means they can feel the happiness of 3D reconstruction. Because of limited accuracy of devices, our final 3D model is not perfect, but generally it can satisfy the needs of recreation in our daily life.
