The Research And Design Of Gesture Interactive System Based On Computer Vision

With the development of computer vision technology and the people of the new interactive means of demand, interactive computer-based vision systems have gradually developed, the traditional methods such as interactive mouse, keyboard, handle, and so on in some specific areas have been unable to play a facilitating The role, because with the development of computer hardware, the emergence of large display device, the interaction of the people means a new challenge, and the interaction based on computer vision can be a very good way to solve the problem, it can be more in line with the thinking of the people Interactive means, the more natural, from the traditional means of interaction in the interface must be fixed.This article was constructed based on computer vision gesture interactive system, in view of the large cluster of laboratory equipment, and 3X3 rear projection display devices and systems through the regular camera equipment shooting gesture action, able to complete the 3X3 projection shows scenes of the strong interaction Action. The whole system running on Linux, divided into server-side (that is, cross-identification) and the client (system control side). And the system can easily migrate to other systems , because the system will not only use a portable C code, and will function under the system is divided into different modules, each module relatively independent to facilitate transplantation and expanded.In this paper, we the first systemic discussed computer interactive technology development, discussed the interaction of computer vision and the general characteristics of the system architecture, a different comparison of the existing interactive computer vision system, described their advantages and disadvantages, after discussing the camera calibration, because the precise control system in the camera calibration is essential, to the camera calibration methods. Then on the gesture recognition and gesture tracking technology, a simple comparison of the colour and model based on statistical probability of colour Gaussian model of the experimental comparison. Focuses on tracking technology in Camshift algorithm, a simple description of Kalman filtering tracking technology, and put forward the idea of combining the two. Finally, the paper by the construction of the system were reviewed, as well as the characteristics of the system and Outlook.The interactive way which based on computer vision is still faced with many challenges, on the one hand because of the visual interaction with the whole life scenes, and scenes of life is changeable and unpredictable, and the scene will be a lot of interference from external factors, such as light ,temperature and so on. How to overcome these difficulties for us with a very big challenge. But with computer technology, especially the improvement of visual processing algorithms, we can overcome these difficulties, for everyone to bring a new interactive way, making people more in line with the interactive way of thinking.
