Abstract
The invention discloses a teaching system based on the augmented reality technology, suitable for emerging education requirements. Under the help of a central processor in a classroom, students wearing spectacle-shaped devices perform full interaction with teaching contents and teachers, so as to get familiar with the teaching contents and cultivate interests. When a teacher draws certain specific figures on the blackboard, cameras of the spectacle-shaped devices worn by the students can send shot figures to a server; the server detects the figures and compares with a database. For example, the teacher draws plane figures of a dam on the blackboard, the spectacle-shaped devices send the figures to the server, the server returns data to the spectacle-shaped devices, and the spectacle-shaped devices superpose the figures on a display screen, so that the students can see a three-dimensional dam figure; through operating a right side touch tablet, the students can rotate and zoom the three-dimensional dam figure, and adjust the transparency of the superposed figure.
Description
Technical field
The present invention relates to a kind of tutoring system, specifically relates to a kind of tutoring system in conjunction with augmented reality, can improve the expressive force of teacher in classroom further.
Background technology
Augmented reality is one of study hotspot of external numerous well-known university and research institution.AR technology is not only in the application similar with VR technology (virtual reality), the fields such as visual, the virtual training of the manufacture and exploit of such as sophisticated weapons, aircraft, data model, amusement and art have a wide range of applications, and due to it, there is the characteristic can carrying out strengthening to true environment display translation, medical research with dissect train, the field such as exact instrument manufacture and maintenance, military aircraft navigate, engineering design and tele-robotic control, there is advantage more more obvious than VR technology.Nowadays the scope of AR has been expanded to and has comprised non-vision and strengthen and application widely, such as advertisement, navigation, military service and amusement etc.In order to make its successful deployment, providing this computer-generated data (image) to be integrating seamlessly in the scene of real world and received increasing concern.
Complete augmented reality system be by one group be tightly linked, the hardware component of real-time working and relevant software systems cooperative achievement, conventional has following three kinds of composition forms.Based in the AR implementation of graphoscope, the real world images of video camera picked-up is input in computing machine, and the virtual scene produced with computer graphics system is synthesized, and outputs to screen display.User sees final enhanced scene picture from screen.Although it is simple, user's how many feeling of immersion can not be brought.
Helmet-mounted display (Head-mounted displays is called for short HMD) is widely used in virtual reality system, in order to strengthen the visual immersion of user.The researchers of augmented reality also use similar display technique, the penetration HMD of widespread use in AR that Here it is.Being divided into again two large classes according to specific implementation principle, is the penetration HMD (Optical See-through HMD) based on optical principle and the penetration HMD (Video See-through HMD) based on Video Composition technology respectively.
Optical perspective formula augmented reality system has simply, resolution is high, do not have the advantages such as vision deviation, but it also also exists simultaneously that positioning accuracy request is high, delay matching is difficult, visual field relative narrower and the high deficiency of price.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide one and have more expressive force, the scheme of the tutoring system that classroom can be made more lively.Traditional classroom instruction uses the oral mode described of projector, blackboard and teacher usually, although can provide enough abundant animation, picture or music, what lack between teacher, student and content of courses three is mutual.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention is made up of three parts, is central server and the related software in glasses shape device and classroom respectively.
1, student is with the device of glasses shape, its similar in existing Google glasses (Google Glass), its profile and common spectacles very nearly the same, but its eyeglass is transparent display screen, on the right side of mirror holder with miniature touchpad so that user operation.Glasses the right and left is installed a high definition optical camera and can be taken 3D scene seen by user in addition.Containing microprocessor and certain data space in glasses, consider the limitation of prior art, microprocessor is it is emphasised that the data transmission capabilities of glasses.Glasses are connected with the server in classroom by existing radio network technique.Figure related operation needs stronger arithmetic capability, the existing microprocessor that can be arranged on glasses does not have so strong arithmetic capability, therefore, by glasses view data of collection etc. sent to the central server in classroom by wireless network, server completes related operation, net result is transmitted back glasses, after glasses process, on eyeglass, shows image.
2, serve as a teacher when to draw some specific figure on blackboard, the high-definition camera of the glasses shape device that student wears can photograph image and be sent to the central server in classroom, and central server detects image, compares with internal database.Such as, teacher draws the planar graph of dam on blackboard, the central server that image is sent to classroom by glasses shape device carries out detection computations, contrast with server internal database, the match is successful, 3D rendering can be taken by the image of two high definition optical cameras, and then can locate in space, server returned data (image that these data mainly will superpose and this image position in space) is to glasses shape device, glasses shape device superimposed image on eyeglass display screen, namely student can see a three-dimensional dam figure (having hidden original plane dam figure on the visual field), by the operation to right side touch pad, student can rotate, the dam figure of this solid of convergent-divergent, and also can adjust the transparency of superposition figure.
3, the related software matched with this tutoring system, mainly use to teacher, teacher install this software on its PC after can be visited the central server in classroom by specific username and password, can upload in the internal database of central server by the material being used for attending class, therefore this tutoring system is extendible.
Compared with prior art, the invention has the beneficial effects as follows:
The classroom instruction of teacher can have stronger expressive force, and student can more fully obtaining information.
Accompanying drawing explanation
Fig. 1 is the tutoring system process flow diagram of this augmented reality.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
Step 1 teacher draws the figure stored in the internal database of central server on blackboard.
The high-definition camera of step 2 student wearing spectacles shape device photographs this figure, and related data is sent to central server by wireless network.
Step 3 central server carries out figure related operation, and operation result is transmitted back glasses shape device.
Step 4 glasses shape device receives data, and superposes virtual image on eyeglass display screen.
Step 5 student is rotated virtual image by the side touchpad of glasses shape device, convergent-divergent and regulate the operation such as transparency.
Optional step teacher is increased by the internal database content of related software to central server that its PC installs, delete and is revised.
The undeclared part related in the present invention is same as the prior art or adopt prior art to be realized.
