Research And Development Of Interactive Virtual Studio System Based On Gesture Recognition

With the continuous development of modern society, the ability of lifelong learning is a basic ability for modern people. If we want to complete the lifelong learning goals, we must cultivate learners'self-study ability. The enhancement of independent study ability is subjective requirements, but in objective respect, there must be efficient rich and vivid learning resources for lifelong learners to complete lifelong learning goals. Existing resources of resources of learning can not adapt to the lifelong learning of modern society and the requirements of informational education. According to the learners'needs, making the learning resources adapting to the informational education requirements is the social requirements.The virtual studio is based on the multimedia technology, computer technology and network. It is the production system of digital cultural products. Using virtual studio can produce the education resources to meet the modern society needs. The digital cultural products produced by the virtual studio system can apply to the field of the education, and as a kind of education resources access. The exising virtual studio system just converge virtual background and foreground actor, and there are no interaction between them. Because of this, the digital cultural products produced by the virtual studio system will become formalist, and the education resources by it will appear boring and stuff. In order to take out more vivid educational resources, there are interaction between virtual background and foreground actor. By means of this manner, it injects fresh blood for traditional virtual studio.Details are as follows:(1) The paper proposes a gesture recognition algorithm based on virtual studio. By establishing template library, preprocessing, detection and tracking of gestures, extracting eigenvalue and recognizing gesture, it can recognize ten static gesture. It provides basis for interacting with 3D background.(2) The paper puts forward a kind of method for interaction with 3D background. Through the result of gesture recognition to judge the movement direction of hand, obtaining the position of hand by the results of the gesture recognition, it uses gestures movement to simulate the mouse related operations. Put the control of 3D background by the mouse control into through gestures to complete.(3) Building an interactive virtual studio system based on gesture recognition. In this system, use the algorithm of the gesture recognition and the method of interacting with 3D background. Shooting out of education resources by this kind of virtual studio system can appear more vivid and interesting.
