Abstract

The utility model discloses a visual man-machine interactive system, which comprises a cradle head, a host computer, a camera, a projector and a wireless control terminal, wherein the camera is arranged on the cradle head, an output end of the camera is connected with the host computer by the aid of a USB (universal serial bus) interface, the wireless control terminal is used for controlling the cradle head wirelessly and remotely and indicating projection of the projector, the camera is used for catching the projection of the projector, an output end of the host computer is connected with an input end of the projector, and the wireless control terminal is connected with the host computer by the aid of a wireless Bluetooth. The visual man-machine interactive system has a remote interactive function so that man-machine interaction is more natural and convenient.

Description

The optic type man-machine interactive system
Technical field
This patent relates to a kind of employing wireless communication technology and realizes remote-controlled operation, realizes at a distance, man-machine interactive system intuitively.
Background technology
Along with the development of society, projection screen also needs to carry out alternately the content on the screen being operated with the user except being used for the demonstration of information, as mark, file movement etc.Traditional interactive mode is to finish by mouse or keyboard, has both disperseed audience's notice, has influenced efficient again, has strengthened the operation power consumption of total system simultaneously.And existing remote indication instrument often only has one-side deixis and lack or do not possess interactive function fully.
The utility model content
The utility model purpose is to provide a kind of optic type man-machine interactive system at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utility model has been announced a kind of optic type man-machine interactive system, comprise The Cloud Terrace, main frame, video camera, projector, wireless control terminal, video camera is arranged on the The Cloud Terrace, the output terminal of video camera is connected with main frame by USB interface, wireless control terminal wireless remote control The Cloud Terrace, the projection of wireless control terminal indication projector, video camera is caught the projection of projector, the input end of the output termination projector of main frame, wireless control terminal is connected with main frame by wireless blue tooth.
Described wireless control terminal comprises laser pen, keyboard, bluetooth sending module, microprocessor and cradle head control device, wherein laser pen and projector relative set, the input end of the output termination microprocessor of keyboard, the output termination bluetooth sending module input end of microprocessor, the projection of laser pen indication projector, cradle head control device wireless remote control The Cloud Terrace.
A kind of system with remote interactive function of the utility model makes man-machine interaction nature and convenient more.

Fig. 2: system hardware block diagram;
Fig. 3: the utility model circuit theory diagrams.
Embodiment
The core technology of native system is an image recognition technology, cooperates virtual input technology again.Native system can be cross-platform, and system adopts the OpenCV computer vision storehouse of increasing income to realize image recognition, drives operation response again, finishes a kind of man-machine interaction based on virtual reality with this.Promptly in certain distance, discern radium-shine light in the action of view field and drive some and need the demonstration of using mouse just can finish at ordinary times.The overall design framework that proposes this patent as shown in Figure 1.
Hardware system mainly is made up of five parts: PC, and camara module, projector module, the laser pen module, the control terminal module, as shown in Figure 2.PC is in system centre, and each peripherals is attached thereto by the video or the communication interface of system.Video acquisition module is made of a video camera that is erected on the self-control The Cloud Terrace.Projector is the display terminal of this system.Laser pen and support circuit are as the equipment of input signal.
Projector and video camera can be placed apart in the system, so the visual angle of different projection angle requirement video cameras also can be different in concrete the use, we have made the DIY The Cloud Terrace that can adjust the visual angle by wireless blue tooth by oneself for this reason.This The Cloud Terrace is by steering wheel, MCU, electric battery, RF module, video camera, compositions such as magic lantern pallet.
Control terminal is as the importation of whole proposal, and it is made up of two parts: one, and laser pen projection circuit; Two, signal wake-up circuit (by the Bluetooth transmission mode).This part circuit diagram as shown in Figure 3, wherein, the red laser pen of 10mw add 4 the joint button cells formed super low-power consumption laser projections circuit.MSP430, RFID, the 4*4 keyboard has been formed control terminals such as wake-up circuit.MSP430 works in the low power consumpting state of LPM3, and the 4*4 keyboard adopts the mode of interrupting to carry out work, and the control of bluetooth also is based on the working method of interruption, greatly reduces the operate as normal power consumption of The whole control terminal.Radio circuit, we have selected 2.4G bluetooth solution for use, have improved job stability, have increased its radiation scope and intensity.
