摘要
和传统接触型交互设备相比,新颖的非触摸型空间交互技术在空间自由度方面有着明显优势.主要探讨基于单目摄像头和简单手势的双手空间交互技术.首先利用肤色分割、滤波优化、运动轨迹预测等算法实现了双手的跟踪与识别.由于需要用空间手势及其运动状态来替代鼠标,提出了基于中心偏离控制和基于线性映射的两种鼠标映射模式,进而实现了四种基本空间手势.基于提出的空间交互技术,实现了软件控制、游戏体验等多个应用.最后讨论了基于单目视觉的双手空间交互技术在手部分割、学习算法、交互方式等方面的改进方向.
Considering the issue of spacial freedom, novel non-touch space interaction precedes traditional interactive devices with touch screen. This paper mainly discusses space interactions based on monocular camera and simple gestures. Firstly, hands tracking and recognition are realized by using skin color segmentation, filter optimization and trajectory prediction. Since mouse movement should be replaced by spacial gestures, two mouse mapping modes（central-bias and linear-mapping） are proposed, based on which, four simple spacial gestures are designed. Based on space interaction technology, this paper implemented various applications such as software control and game experience. Future improvements are then discussed, including hand segmentation, learning algorithm and interaction modes.
