摘要基于计算机视觉的人机交互是自然人机交互技术领域的研究热点，它利用视觉信息从视频序列中捕获并理解人的肢体动作，使人与计算机之间的交互摆脱了鼠标及键盘的约束，人只需要通过肢体动作、手势、表情等自然信息就能与计算机进行交流，突破了从计算机诞生至今在人机交互过程中必须由人来适应机器的屏障，使人与计算机之间的交流更加自然、流畅。
本课题以手势识别为主要研究内容，在深入分析计算机视觉、人机交互、静态手势识别等方法基础上，研究手势动作与虚拟场景中三维物体的自然交互技术，并基于OpenCV库设计和实现了一个手势识别与虚拟三维空间人机交互系统。59673

Title Virtual Scene Interactive Technology Based on Gesture
Abstract
Human-computer interaction based on computer vision,which uses visual information captured from video sequences and understands the body movements,is a hotpot in natural Human-computer interaction technology area.It makes the interaction between human beings and the computer get rid of the constraints of mouse and keyboard.So people can communicate with the computer only by body movements, gestures, facial expressions and other natural information that breaks the barrier of people must adapt to the machine in the process of Human-computer interaction since the birth of the computer,which makes the communication between human beings and computers more natural and more smooth.
To take gesture recognition as the main contents,this task studied gestures and natural interaction techniques of three-dimensional objects in the virtual scenes on the basis of depth analysis of methods of computer vision,Human-computer interaction,recognition of the static- gestures,designed and implemented a gesture recognition and Human-computer interaction systems in virtual three-dimensional space based on the OpenCV library.
