Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, hereafter will by reference to the accompanying drawings technical solution of the present invention be described in further detail. It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine arbitrarily mutually.
Embodiment 1
The present embodiment provides a kind of method controlling Projection Display, its combined with intelligent projector apparatus and image recognition technology, can realize control project content and laser pen interaction in projection process. The method mainly comprises following operation:
Smart projector gathers the image of laser pen motion track in real time in the setting regions on projection plane;
The image of the laser pen motion track gathered is carried out identifying processing by smart projector;
The view data that identifying processing result is corresponding with preset every control operation is mated by smart projector respectively, if the match is successful, then smart projector processes according to the control operation that the match is successful.
Wherein, the view data that preset every control operation is corresponding, it is possible to be that smart projector is preset in advance according to user instruction, it is also possible to be smart projector initialize default setting.
In addition, smart projector can also according to user instruction, the display color of the laser pen that preset every control operation is corresponding. Namely the display color of laser pen is different, and its control authority can also be different.
Specifically, smart projector can by word interactive mode prompting user's initial work. Smart projector is when starting to detect projection plane light source, it is possible to according to the display color of laser pen and user's use habit, configuration interactive strategy, simultaneously preset can drawing area (i.e. setting regions), avoid overlapping with displaying contents region.
Such as, smart projector by attached camera collection laser pen light source reflection frequency, can allow its controlled appointment " controller ". Namely the image taken by camera is carried out digital image processing in setting regions and (can reduce calculated amount, improve precision and arithmetic speed), detection laser is projected on screen color line by line, the pixel value mutation caused with adjacent " in vain " region by RGB color, locking laser pen projected color, turns to acquiescence laser controlling color.
Smart projector by attached camera collection laser pen light source motion track, by digital image processing techniques comprehensive descision, can also set respond style. Namely when PPT gives a lecture, picture is fixing, camera is by shooting continuously, when there being RGB color value mutation in designated area, nearby tens of for front and back two field picture can be compared coincidence, so can dynamically draw the track that lecturer is drawn by laser pen, carry out corresponding control operation, such as display operation (lower one page, page up) of skipping, return master menu, shutdown etc.;
Assume that the control that preset square is corresponding is operating as and return master menu operation.
The control that trilateral is corresponding is operating as power-off operation.
Return the control hooking correspondence and it is operating as page up (approximate back key) operation. :
The control of line correspondences is operating as lower one page (near linear, left-to-right) operation.
In addition, smart projector can also point out user operable area, and reappear user and used the laser pen corresponding smart projector action of display track, and as operated basic ppt function, smart projector is simply shut down, adjusted brightness etc.
Preferably, after identifying processing result and preset every control view data corresponding to operation are mated by smart projector, if the match is successful, it is possible to user show the control that the match is successful operate, when user confirms that performing this control operates, then process according to the control operation that the match is successful. Mishandle can be avoided like this, thus improve the reliability of control operation.
Embodiment 2
The present embodiment provides a kind of device controlling Projection Display, at least comprises following each unit.
Collecting unit, gathers the image of laser pen motion track in real time in the setting regions on projection plane;
