Research On The Algorithm Of Human Motion Detection In Interactive Projection System

With the multimedia technology in recent years, the development of computing technology and virtual reality technology, interactive projection is becoming common interactive information display and entertainment tools in daily life. This technique is motion detection technology and virtual reality technologies, the main use of motion detection technology to detect and analyze human motion information, and with the corresponding projection background, people feel the changes in their bodies by bringing changes in the virtual world, people have a immersive feel.In this paper, an interactive projection of human motion detection algorithm to study attitude, and to analyze the movement of human hand gesture information and test analysis. For the complex interaction of environmental background, analysis of the actual separation of the difficulty of human motion information, so proposed infrared technology as the method of separating moving objects with the human. Attitude in the analysis of human motion algorithm, the paper discusses several motion detection algorithms and edge detection algorithm, combined with the advantages and disadvantages of each method, according to different virtual scene, discuss the combination of edge detection algorithms and time difference and the combination of time difference and optical flow to analyze the general gesture of human hand movement, that is the general direction of human hand movement, and then use the appropriate background to achieve the projection interactive projection effects.
