Augmented-reality-based three-dimensional interactive learning system and method

Abstract

The invention provides an augmented-reality-based three-dimensional interactive learning system and an augmented-reality-based three-dimensional interactive learning method. The system comprises an information processing device, a photographic device, a display device and at least one physical teaching aid, wherein the physical teaching aid is provided with identification information; the photographic device is used for performing video acquisition on a real environment after augmented reality application is started; and the information processing device comprises an identification module for identifying the identification information on the physical teaching aid, an orientation calculation module for calculating the spatial orientation information of the physical teaching aid, and a three-dimensional rendering module for acquiring a three-dimensional model corresponding to the identification information, rendering and generating a corresponding virtual object, and placing the virtual object at a corresponding position in a video image for display according to the spatial orientation information of the physical teaching aid. According to the system and the method, the real environment and the virtual object are overlapped in the same scenario in real time, so that a more vivid sensory experience is provided for a user, and meanwhile, a teaching effect is improved by utilizing the instinct of a person for the recognition of a three-dimensional space.

Description

technical field [0001] The invention relates to the technical field of multimedia interactive teaching devices, in particular to a three-dimensional interactive learning system and method based on augmented reality. Background technique [0002] At present, the more mainstream multimedia teaching devices on the market include early childhood education machines, point reading machines, point reading pens, e-books / schoolbags, literacy cards, and computer education software. The existing multimedia teaching device has the following defects: [0003] 1. Traditional multimedia teaching devices have low interest and are difficult to mobilize children's initiative. [0004] 2. The operation of multimedia teaching devices for high-tech education is relatively complicated, and the user threshold is relatively high. [0005] 3. There is no good multimedia teaching device that can drive family interaction. [0006] With the continuous advancement of the computer age, the proportion ...

AI Technical Summary

Problems solved by technology

[0003] 1. Traditional multimedia teaching devices are not very interesting, and it is difficult to mobilize children's initiative

[0004] 2. The operation of multimedia teaching devices for high-tech education is relatively complicated, and the user threshold is relatively high

[0005] 3. There is no good multimedia teaching device that can drive family interaction

[0008] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
