Based on the mutual education method and system of natural image identification and augmented realityTechnical field
The invention belongs to augmented reality and natural image identification and processing technology field, relate to and a kind ofly use above two kinds of technology to realize the system and method for mutual education on mobile terminals.
Background technology
The existing system or equipment for educating is the educational electronic product that children's early education promotes child learning interest specially, such as children education machine, can comprehensive training learning ability of children, promotes have very great help to aspects such as child's notice, thinking abilities.But also coming with some shortcomings in prior art, is first all unidirectional study, and student can not from main separation learning content; Secondly, effectively do not utilize new technology to educate, such as image identifying and processing technology, applied only for Quick Response Code identification now, more rudimentary; Also have AR augmented reality, be also not yet applied.
Above-mentioned image identifying and processing technology, refers to and utilizes computing machine to process image, analyze and understand, to identify the target of various different mode and the technology to picture.The identification having bar code, Quick Response Code of image recognition technology common at present, the identification for natural image also develops with process.
Virtual information by computer technology, combines with real world by above-mentioned AR augmented reality, and be added in real time same picture or space of real environment and virtual object exists simultaneously.It by the dummy object of Practical computer teaching or about the non-geometry information of real-world object be added to real world scene on, achieve the enhancing to real world.The principal feature of augmented reality is that actual situation combines and man-machine interaction.The main application vector of early stage augmented reality is portable computer or head mounted display, abnormal heavy.Along with extensively popularizing of mobile intelligent terminal, augmented reality is widely used in mobile intelligent terminal.
What need solution at present badly is exactly in the education product that image recognition technology and augmented reality are applied, and realizes high-tech mutual education.
Summary of the invention
The object of this invention is to provide a kind of system and method realizing mutual education based on natural image recognition technology and augmented reality on mobile intelligent terminal, solve problems of the prior art.
In order to achieve the above object, the technical scheme that the present invention takes is: a kind of mutual education method based on natural image identification and augmented reality, is characterized in that, comprise the steps:
(1) camera of mobile intelligent terminal scans Quick Response Code or natural image acquisition download link;
(2) augmented reality AR manager is downloaded;
(3) education APK is downloaded by augmented reality AR manager;
(4) the education APK of download is opened, the natural picture in camera identification reality scene, and the educational system of natural picture transfer to server;
(5) by AR image recognition, the educational system of server is from the data base call augmented reality education content corresponding with the natural picture of identification;
(6) augmented reality education content is transferred to mobile intelligent terminal screen;
(7) learner is in conjunction with the scene of captured in real-time and augmented reality education content, viewing interactive, study.
Preferably, in step (4), choose the unique point of some fixed position in nature picture, by the educational system of the information transmission entrained by these unique points to server;
Preferably, the AR image recognition described in step (5), its method is:
A. make recognition image material, according to color contrast, the correlation means such as lines change produce recognition image;
B. recognition image material is changed into the discernible image of program by high pass algorithm;
C. recognition image is nature picture;
D. import unity3d AR framework and build programming system;
E. interaction is carried out by corresponding image card and book.
Preferably, the described augmented reality education content of step (5) comprises augmented reality education video, augmented reality education audio frequency, augmented reality teaching picture.
Another aspect of the present invention, a kind of interactive education system based on natural image identification and augmented reality, is characterized in that: the server comprising system place, and mobile intelligent terminal; Described mobile intelligent terminal connects described server by mobile network; Described mobile intelligent terminal comprises mobile terminal camera module, natural image identification module, data processing module, augmented reality education content output module and augmented reality interactive module.
Further, described server comprises augmented reality AR manager module, education APK module and download module, described real AR manager module, education APK model calling download module.
Further, described augmented reality education content output module comprises augmented reality education video module, augmented reality education audio-frequency module, augmented reality teaching picture module.
Beneficial effect of the present invention is: natural image recognition technology combines with augmented reality by the present invention, is applied on mobile intelligent terminal, to realize aims of education; Mostly intelligent education machine in the market, learning machine are simply enumerating of course and pile up, and the technology of the interaction really can accomplished between intelligent education machine and learner does not almost have; Used the present invention of augmented reality really to achieve this interaction, learner can unrestricted choice learning content simultaneously.Current most augmented reality is all use planar bar code technology to identify recognizate, and the present invention adopts natural image identification, and recognition speed is rapider, more stable, learns also more interesting.Advantage of the present invention: 1. natural image identification; 2. possesses interactive attribute; 3. the use of mobile intelligent terminal is convenient.

Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Education terminal in the market all presents unidirectional mode of learning, the passive content of accepting the education of learner, and native system solves this problem, native system application augmented reality, makes study and education present two-way interaction pattern.This educational system and method can make learner feel more vivid, more on the spot in person.
Step of the present invention as shown in Figure 1.
(1) camera of mobile intelligent terminal scans Quick Response Code or natural image acquisition download link;
(2) augmented reality AR manager is downloaded;
(3) education APK is downloaded by augmented reality AR manager;
(4) the education APK of download is opened, natural picture in camera identification reality scene, and the educational system of natural picture transfer to server, its process is the unique point of some fixed position chosen in nature picture, by the educational system of the information transmission entrained by these unique points to server;
(5) by AR image recognition, the educational system of server is from the data base call augmented reality education content corresponding with the natural picture of identification;
Wherein AR knowledge method for distinguishing is:
A. make recognition image material, according to color contrast, the correlation means such as lines change produce recognition image;
B. recognition image material is changed into the discernible image of program by high pass algorithm;
C. recognition image is nature picture;
D. import unity3d AR framework and build programming system;
E. interaction is carried out by corresponding image card and book;
In addition, described augmented reality education content comprises augmented reality education video, augmented reality education audio frequency, augmented reality teaching picture, as shown in Figure 2.
(6) augmented reality education content is transferred to mobile intelligent terminal screen;
(7) learner is in conjunction with the scene of captured in real-time and augmented reality education content, viewing interactive, study.
