摘　　要：近年来,随着三网融合概念的兴起,家庭多媒体设备功能的日趋完善,其控制与使用也变得越来越复杂,如何使家庭多媒体设备控制实现简单化、统一化、易用化成为相关行业亟待解决的问题。通过人们手指细微的运动,更使用户能够直接快速地完成空间键盘输入的功能,从而极大地提高用户的操作体验。Kinect作为一种新型的体感设备,可以获得精确的RGB图像信息和深度图像信息,是准确快速地获得用户的指尖定位成为可能。本系统通过深度图和RGB图相结合的方法,进行手型分割。通过指尖检测所得二维指尖坐标,反向求出指尖点的三维空间坐标。对于由指尖点、凹缺陷点和掌心点所组成的手部三维空间模型,判定计算键盘输入行为。此系统基本实现了隔空键盘输入的功能,但在边缘区域的识别率相对较低。In recent years,with the rise of three nets fusion, family multimedia equipment function is progressing, the control and use is also becoming more and more complicated, how to make the control of family multimedia equipment become simplification, unification and easy to use become urgent problem to be solved for relevant industry. Through people finger subtle movement, the user can quickly complete keyboard input,thus greatly improve the feeling of the user＇ s operation. Kinect as a new type of body feeling equipment,can obtain accurate RGB image information and depth image information,and making it possible to accurate and fast for the user＇ s fingertip location. This system by the method of combination of depth map and RGB figure,is used to identify the hand area and the segmentation. From two-dimensional fingertips coordinates measured by fingertips,we can get the three-dimensional space of fingertip point coordinates. With finger tip point,concave defect points and the palm of the hand＇ s three-dimensional model, determining when and where keyboard input behavior happen. This system basically realized the function of keyboard input from a distance,but the recognition rate is relatively lowin the edge region.
