Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a projection system, and more particularly to an interactive projection system. [Prior Art] The interactive projection system is divided into two modes: front projection and rear projection. The so-called front projection mode means that the projector, camera and user are on the same side of the screen (which can be the screen, wall, floor or any surface on which the image can be projected). In addition, the rear projection mode means that the projector and the camera are on the side of the screen, and the user is located on the other side of the screen with respect to the projector and the camera. The technical limitation of the interactive projection system based on the rear projection mode is that, in general, the manner in which the user inputs the operation command is not processed by the camera as the operation command by the camera, but the touch film is provided. The user can touch the touch film to input an operation command, or set an infrared sensor on the edge of the screen to sense the coordinate point blocked by the user, and use Φ as an input operation instruction. Although the interactive projection system of the rear projection mode has the advantages of space saving and easy setting compared with the interactive projection system of the front projection mode, the current interactive projection system of the rear projection mode uses a touch film or an infrared sensor. The method provides a user input operation instruction, and therefore, the current interactive projection system of the rear projection mode has the disadvantage of high manufacturing cost.
