Multi Touch Target Tracking Algorithm in Optical Multi-Touch Systems

With the continuous progress and development of science and technology, the development of computer hardware has become an indispensable part of people’s lives, and multi-touch systems are widely used in new human-computer interaction technology. The role in the field of computer vision technology is important, but there is a problem of inaccurate identification. Classical human-computer interaction methods cannot solve the problems of target recognition rate, tracking accuracy, and poor multi-touch integration. Therefore, this paper proposes an optical tracking method to innovate and improve multi-touch system analysis. First, according to the advantages and disadvantages of contact tracking, the indicators are divided according to the requirements of the multi-touch system to reduce the interference factors in the multi-touch system. Then, combined with the target extraction method and the optical contact space-time position tracking method, a multi-touch system scheme is formed, and the multi-touch system results are comprehensively analyzed. MATLAB simulation shows the accuracy, target recognition rate and optical feature utilization of optical tracking method for multi-touch system target tracking under the condition of a certain average background Optimal traditional contact detection algorithm.
