THREE-DIMENSIONAL INTERACTIVE LEARNING SYSTEM AND METHOD BASED ON AUGMENTED REALITY

摘要

Provided are a three-dimensional interactive learning system and method based on augmented reality. The system comprises an information processing device, a photographing device, a display device, and at least one physical teaching tool. The physical teaching tool is provided with identification information. The photographing device is used to capture a video of the real environment after an augmented reality application is activated. The information processing device comprises: an identifying module, used to identify the identification information on the physical teaching tool; an orientation calculation module, used to calculate spatial orientation information of the physical teaching tool; and a three-dimensional rendering module, used to acquire a three-dimensional model corresponding to the identification information, render the model, generate a corresponding virtual object, place the virtual object in a corresponding position of a video image according to the spatial orientation information of the physical teaching tool, and display the virtual object. In this way, the present invention can superpose the real environment and the virtual object in a same scenario in real time, provide a more vivid sense experience for the user, and improve a teaching effect by using the human instinct of cognizing the three-dimensional space.
