Abstract: Augmented reality is usually limited to the screen devices, and is difficult to realize the stereoscopic dynamic interaction of multiplayer. A large screen interactive display method based on the servo motor is prsented. The serial communication program to control the scanning reciprocating mode of the servo is designed. By using the edge detection methods and deep normal texture processing, the line draft of the ancient buildings is rendered. By combining the hardware and presentation application modules, the user interaction capabilities and seasonal effects is added to the showcase application modules. The experimental results show that the interactive media system for the ancient buildings based on the servomotor realizes the scanning motion of the servomotor, the screen renders the effects of the ancient building according to the position information of the servomotor, and the user can interact with the system friendly. The system has been applied well in the actual project.

Key words: Augmented reality, transparent touch screen, servo motor, edge detection
