Abstract

The utility model discloses an infrared virtual reality teaching system based on Wiimote, which consists of a projector, a projection screen, a computer, a Wiimote camera and a marker, wherein the projector, the Wiimote camera and the marker are positioned on the same side of the projection screen and face towards the front side of the projection screen; and the computer is respectively connected with the projector and the Wiimote camera, and is provided with a video capture card. With the infrared imaging principle of the camera, the utility model not only can conveniently realize the function of the existing interactive virtual reality teaching system, and realize the multi-point control and long-range control without contact with the screen, but also has low cost, is free from the special virtual reality teaching system projection screen, is convenient and flexible to use, and is easy to lay out.

Description

Infrared virtual reality tutoring system based on Wiimote

Technical field

The utility model belongs to electronic applications, relates to a kind of instructional device, especially a kind of infrared virtual reality tutoring system based on Wiimote.

Background technology

The virtual reality tutoring system can help to express viewpoint and thought preferably.A critical problem is a positioning feature point in the virtual reality tutoring system system.The sensor that current production is located employing mainly adopts piezoelectric type, electromagnetic type and infrared scan grid sensor, feasible deployment and mobile difficult, and while production flow process is complexity, and price is costliness comparatively, has brought certain difficulty to universal and use.

The utility model content

The utility model positions unique point by the Wiimote camera, in conjunction with computing machine and micro projector, in the interactivity that strengthens teaching and expressive force, more flexibly and be easy to deployment, has reduced cost.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of infrared virtual reality tutoring system based on Wiimote is provided, and this virtual reality tutoring system is made of projector, projection screen, computing machine, Wiimote camera and marker; Described projector, Wiimote camera and marker are positioned at the projection screen homonymy and towards the projection screen front; Described computing machine is connected with the Wiimote camera with projector respectively; Described computing machine is provided with video frequency collection card.

Described Wiimote camera is provided with infrared filter.Described marker is the infrared laser pen, and this infrared laser pen comprises pen cover, a body, touch pad, switch and infrared laser lamp.The utility model utilizes camera infrared imaging principle not only can realize the function of present interactive virtual reality tutoring system easily, can also realize that multiple spot is controlled simultaneously and with the contactless Long-distance Control of screen, and cost is low, do not need special-purpose virtual reality tutoring system projection screen, convenient, flexible, be easy to dispose.

Description of drawings

Fig. 1 is an outer virtual reality tutoring system structural representation of the present utility model.

Wherein: 1 is computing machine; 2 is projector; 3 is the Wiimote camera; 4 is marker; 5 is projection screen.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail: referring to Fig. 1, a kind of infrared virtual reality tutoring system based on Wiimote, this virtual reality tutoring system is made of projector, projection screen, computing machine, Wiimote camera and marker; Described projector, Wiimote camera and marker are positioned at the projection screen homonymy and towards the projection screen front; Described computing machine is connected with the Wiimote camera with projector respectively; Described computing machine is provided with video frequency collection card.Described Wiimote camera is provided with infrared filter.

Described marker is the infrared laser pen, and this infrared laser pen comprises pen cover, a body, touch pad, switch and infrared laser lamp.This virtual reality tutoring system system is made up of micro projector (or general projectors), projection screen, computing machine, Wiimote camera and marker.Nib at the virtual reality teaching pen is installed the infrared laser transmitter, infrared laser is radiated on the virtual reality tutoring system screen and forms hot spot, caught by the Wiimote camera, image passes to computing machine through capture card, and calculate the position of nib, thereby the location of having realized nib with respect to screen by image processing algorithm.Utilize the locating information of pen to realize corresponding operating and generate image then, utilize projector that picture material is projected on the teaching screen, construct a giant-screen, interactively cooperation meeting or teaching environment with this according to user's request.System supports portable projector in addition, on one's body can being carried at, but to any plane of reflection executable operations all.System divides two kinds, a kind ofly is to use large-scale fixedly projector, gives lessons for the top class in a kindergarten and designs, also has a kind of micro projector that is to use, not only can be used for bottom class and give lessons, also can be used for teacher office, can directly be incident upon Key for Reference on the homework book when correcting students' papers.

Owing on the projection lens of projector the IR-cut filter is housed usually, so infrared composition is considerably less in the light that projection goes out.Therefore, infrared laser transmitter and laser controlling switch are installed on teaching pen, laser beam is beaten and form the infrared light hot spot on screen, can be able to be responded to the camera of infrared light and catch clearly.The gained image is passed to computer, thereby carries out respective handling by the position that processing calculates pen, generates image, utilizes projector that picture material is projected on the virtual reality screen.Simultaneously, installation function button and send signal by wireless mode on teaching pen receives with the wireless module of USB interface, sends to computing machine and can realize expansion to operating function, finishes the mouse right click, operation such as page turning up and down.

Wherein, the infrared filter of 850nm can be removed the interference of the infrared light spot that light (projection ray and daylight) medium wavelength sends virtual reality tutoring system pen less than the composition of 850nm, has strengthened the robustness of system, has simplified the difficulty of system structure design greatly.

Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
