Problems solved by technology

[0004] 1) The presentation of digital information is not intuitive enough
Since the presentation of digital information mainly relies on two-dimensional display screens or projections, in many educational scenes where three-dimensional models need to be displayed, the two-dimensional plane can only be observed from one or several angles, which is not intuitive enough
[0005] 2) The area displayed by multimedia information is generally relatively small, which cannot give students an immersive feeling
Moreover, if there are only a few screens in the entire classroom, since the screens are generally placed at the front of the classroom, students sitting in the back row may not be able to see the screen clearly
[0006] 3) Generally, only the teacher can control the playback of the multimedia information, and the students can only follow passively, which is not very flexible

The display module 12 is arranged on the upper side of the see-through light guide element 13 , and the light emitted by the display module 12 can pass through the see-through light guide element 13 and be reflected. Optionally, the display module 13 can also be located at the side of the see-through light guide el...

Embodiment 2

[0069] refer to Figure 7 , on the basis of the teaching aid device based on augmented reality provided in Embodiment 1, a plurality of sensors are set to perceive the surrounding environment.

[0070] This embodiment provides a teaching aid based on augmented reality, the total weight of the augmented reality based teaching aid is less than 350 grams, which includes: a head-mounted frame 21, two display modules 22, two see-through light guides Component 23 and motherboard 24.

[0071] The display module 22 , the see-through light guide element 23 and the main board 24 are all arranged on the head-mounted frame 21 , and the head-mounted frame 21 fixes the display module 22 , the see-through light guide element 23 and the main board 24 . The display module 22 is arranged on the upper side of the see-through light guide element 23 , and the light emitted by the display module 22 can be reflected after passing through the see-through light guide element 23 . A main board 24 , the...

Embodiment 3

[0105] This embodiment provides a teaching assistance method based on augmented reality, including:

[0106] emitting a first ray containing the virtual image;

[0107] Obtaining a second ray of the real-world image containing the teaching scene;

[0108] Synthesizing the first light containing the virtual image and the second light containing the real image of the teaching scene.

[0109] The acquiring the real scene image of the teaching scene includes acquiring the second light reflected from any real object or scene in real time in the teaching scene. For example, the acquired real scene images include: images of students in the classroom, desks and chairs, learning utensils and other objects that are reflected by light, or images of other scenes and objects that are reflected by light.

[0110] The acquiring the virtual image includes: acquiring the image displayed by the display module 12 after being processed by the processor. Exemplarily, the virtual image includes:...

Abstract

The embodiment of the invention discloses a teaching assistant method based on the augmented reality, which comprises the steps of sending first light containing a virtual image; obtaining second light containing a live-action image of a teaching scene; and synthesizing the first light containing the virtual image and the second light containing the live-action image of the teaching scene. Different from the prior art, the teaching assistant method provided by the embodiment of the invention based on the augmented reality combines the live-action image of the teaching scene with the virtual image, the virtual image can provide information tips for a user so as to assist the user to perform teaching, the user experience is good, and the use is convenient.

Description

technical field [0001] The embodiments of the present invention relate to the field of augmented reality technology, in particular to an augmented reality-based teaching assistance method and device. Background technique [0002] At present, various educational institutions widely use televisions, projectors, etc. to play multimedia materials, such as video and audio, when teaching courses. The use of multimedia materials can effectively make the teaching process vivid, which is convenient for students to remember and improve the educational effect. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the related art: [0004] 1) The presentation of digital information is not intuitive enough. Since the presentation of digital information mainly relies on two-dimensional display screens or projections, in the case of many educational scenes that need to display three-dimensional models, it can only...
