Abstract: Since augmented reality technology has the features of real-time interaction with the userand the high degree of integration of the “virtual and real”, it has been applied into various fields rapidly. However, such technology is rarely used into the stage performance field, because it is difficult for actors to interact with display system in real time. Stage performance effects are usually obtained through video display, the actors need accurately match the video content in order to achieve the desired artistic effect, this seriously constrains the actor’s performance. To solve the problem, this paper proposes a real-time interactive system based on infrared camera. The system shows the corresponding rendering image according to the action of the actors in real-time, which completely liberates the shackles of the actors and coordinates the man-machine relationship of the actor and display system, making the stage effect determined by the actors rather than by the video passively. The system has been successfully applied to a number of formal performances of the stage play and provides a new idea for the stage interactive method.
