Sensors are laid on the projection screen. The gesture control device comprises a visible light track obtaining module and a track drawing module. Plane coordinates of a light spot projected by the visible light emitting pen onto the screen are obtained through a sensor set on the projection screen, a drawing button of the visible light emitting pen is pressed, a track is drawn on the projection screen in a movement mode, the gesture control device outputs coordinates of the track to the projector, and the projector projects the corresponding track to the projection screen. According to the screen visible-light-track tracking projection system, a track drawing method is easy and convenient to operate and high in reliability.
Description
Technical field
The present invention relates to a kind of projector projection system, particularly a kind of projection projection system following the tracks of screen visible ray track.
Background technology
The use of projector is very universal, when speaker utilizes projector slide show, a laser pen launching brightly painted visible ray generally can be used to carry out auxiliary presentation during emphasis in order to outstanding shown slides sheet.Its shortcoming is, when certain position is special emphasis, and speaker spends more a time explanation again on this emphasis, and its laser pen of holding sends light and just must rest on keypoint part always.In addition, we know that the PowerPoint of Microsoft can use an instrument being called " pointer option " when slide show, it is similar to and draws lines to give top priority to what is the most important with pen on the screen of projection, and its shortcoming is to use mouse control, and this brings a lot of inconvenience to actual presentation operation.
Summary of the invention
For solving the problem to the screen control inconvenience of projection in prior art, provide a kind of projection projection system following the tracks of screen visible ray track, this projection system is reasonable in design, control is convenient.
For achieving the above object, the present invention is by the following technical solutions:
A kind of projection projection system following the tracks of screen visible ray track, comprise projector, projection screen, gesture control device, projection screen, VISIBLE LIGHT EMISSION pen are connected with gesture control device, and gesture control device is connected with projector, and VISIBLE LIGHT EMISSION pen is provided with laser beam emitting device and draws button;
Described projection screen is equipped with sensor, and sensor is connected with gesture control device;
Gesture control device comprises visible ray track acquisition module and track drafting module;
Visible ray track acquisition module, launch pen be incident upon track on screen for obtaining, the sensor on projection screen obtains the position that VISIBLE LIGHT EMISSION pen projects the hot spot on projection screen, positional information input visible ray track acquisition module;
Track drafting module, for exporting the track that need draw to projector, goes out the track that need draw to screen prjection by projector.
Above-mentioned a kind of projection projection system following the tracks of screen visible ray track, the sensor that projection screen is laid is made up of spaced linear photosensor resistance, linear photosensor resistance is divided into two-layer, and the linear photosensor resistance on upper strata is transversely arranged, and lower floor's linear photosensor resistance is vertical arrangement; The spacing of linear photosensor resistance is less than the diameter of visible ray class.
Above-mentioned a kind of projection projection system following the tracks of screen visible ray track, the linear photosensor electric resistance sensor that projection screen is laid comes together in total interface, total interface output terminal is connected with gesture control device, and total interface is used for the simulating signal of sensor being converted to digital signal and flowing to gesture control device.
Before normal use the present invention, regulate position and the angle of projector, the view field making it to project is within the projection screen being equipped with sensor group, the light class of VISIBLE LIGHT EMISSION pen is greater than the spacing of linear photosensor resistance, photoresistance is irradiated by VISIBLE LIGHT EMISSION pen, produce resistance variations, thus the planimetric coordinates that VISIBLE LIGHT EMISSION pen is incident upon the hot spot on screen can be obtained, when visible ray track drawn by needs, press the drafting button of VISIBLE LIGHT EMISSION pen, move out track on the projection screen, gesture control device is to the coordinate of projector output trajectory, projector projects goes out track, unclamp the drafting button of VISIBLE LIGHT EMISSION pen, the track of VISIBLE LIGHT EMISSION pen movement just retains on the projection screen.The present invention is in the method for track drafting, easy and simple to handle, and reliability is high.
Accompanying drawing explanation
Fig. 1 is present system one-piece construction schematic diagram.
Fig. 2 is present system process flow diagram.
Fig. 3 is the structural representation of the linear photosensor resistance that projection screen of the present invention is laid.
Be labeled as in figure: 1 projector, 2 gesture control device, the view field of 3 projector projects, 4 projection screens, 41 transversely arranged photoresistance, the photoresistance of 42 longitudinal arrangements, 5 tracks drawn, 6 hot spots, 7 VISIBLE LIGHT EMISSION pens, 8 launch the drafting button on pen.
Embodiment
With reference to accompanying drawing, a kind of projection projection system following the tracks of screen visible ray track, comprise projector 1, projection screen 4, gesture control device 2, projection screen, VISIBLE LIGHT EMISSION pen 7 are connected with gesture control device, gesture control device is connected with projector, and VISIBLE LIGHT EMISSION pen is provided with laser beam emitting device and draws button 8; The sensor that projection screen is laid is made up of spaced linear photosensor resistance, and linear photosensor resistance is divided into two-layer, and the linear photosensor resistance 41 on upper strata is transversely arranged, and lower floor's linear photosensor resistance 42 is vertical arrangement; The spacing of linear photosensor resistance is less than the diameter of visible ray class; Linear photosensor resistor group comes together in total interface, and total interface output terminal is connected with gesture control device, and total interface is used for the simulating signal of sensor being converted to digital signal and flowing to gesture control device.
Gesture control device comprises visible ray track acquisition module and track drafting module;
Visible ray track acquisition module, launches pen be incident upon track on screen for obtaining.Linear photosensor electric resistance sensor group on projection screen is owing to producing the change of different resistance values by illumination, when VISIBLE LIGHT EMISSION pen projects on projection screen, the planimetric position of visible light spot can be known, by total interface by the positional information of hot spot input visible ray track acquisition module by linear photosensor electric resistance sensor group;
Track drafting module, for exporting the track that need draw to projector, goes out the track that need draw to screen prjection by projector.
When using native system, adjustment projector, the light area 3 that projector projects is gone out falls in projection screen, on VISIBLE LIGHT EMISSION pen projection hot spot 6 to projection screen, when needs track drafting to mark key content on screen, press the drafting button on VISIBLE LIGHT EMISSION pen, move VISIBLE LIGHT EMISSION pen simultaneously, the track walking that the hot spot making it launch is drawn on demand, walk complete, unclamp drafting button, projection screen is while VISIBLE LIGHT EMISSION pen is launched, the launching position of hot spot is synchronously obtained by linear photosensor electric resistance sensor group, the track drafting module of gesture control device exports track drafting instruction to projector, on projection screen, the shift position of hot spot is projected by projector, synchronous track drafting, unclamp drafting button, gesture control device stops exporting rendering order to projector, and notify the track that projector continues Projection Display and just now drew.
