Description
Technical field
The utility model relates to the image projection technology field, more particularly, relates to a kind of interactive projection system.
Background technology
At present, the image projecting technology reaches its maturity, and has had many high-quality projector equipments to come out, and these equipment have very high image definition and image projecting effect.Yet existing projector equipment only is as simple output device, can only show predefined content and in-order influence, can't realize alternately, lack property of participation.In some occasions,, need control displaying contents by main frame, troublesome poeration as giving a lecture, give lessons etc.
For this reason, a kind of interactive display system occurred, adopted main frame, show control alternately by computer-controlled image projector, laser designator and projection screen.Main frame produces the electronic image project on the projection screen as display image.In operating process, utilize the variation of the cursor indication point light on and off signal frequency of laser designator to come a plurality of handoff functionalities in the object computer, realize in projection screen epigraph and the computing machine image alternately.Yet, adopt laser designator only to be only applicable to the operation of some simple page turnings, amplification etc., user's participation is still lower, is unfavorable for some interactive higher occasions, for example interactive advertisement recreation projection etc.
The utility model content
The technical problems to be solved in the utility model is, the interactive relatively poor defective at the above-mentioned interactive display system of prior art provides a kind of interactive strong interactive projection system.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of interactive projection system, comprise main frame and the projector of being controlled by described main frame; The video frequency collection card that this system also comprises the video camera of catching the moving target video and gathers the video that described video camera catches; Described main frame connects described video frequency collection card and produces projected image according to the video that described video frequency collection card is gathered; Described projector is connected with described main frame and the described projected image of projection.
In interactive projection system described in the utility model, described main frame comprises image analyzing unit that each frame of video of described video frequency collection card collection is analyzed and the Graphics Processing Unit that produces projecting figure according to the result of described image analyzing unit analysis.
In interactive projection system described in the utility model, it is the action video of moving target that described video camera is caught the moving target video.
In interactive projection system described in the utility model, the zone of the moving target that described video camera is caught and the zone of described projector projected image are at the same area.
Implement interactive projection system of the present utility model, has following beneficial effect: with figure and image technique combination, detect the video of moving target by video camera seizure video, capture card collection video, realtime graphic treatment technology, produce real-time graph by computing machine simultaneously, project to places such as ground, wall, roof at last by projector, produce the effect of human-computer interaction, thereby make human-computer interaction more reasonable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation block diagram of the utility model interactive projection system.
Embodiment
As shown in Figure 1, in an embodiment of interactive projection system of the present utility model, this system comprises main frame 10, projector 20, video camera 30, video frequency collection card 40 etc.This main frame 10, projector 20, video camera 30 and video frequency collection card 40 can be installed in the same carrier, and carrier is installed to suitable position, for example position such as smallpox, wall.Carrier is provided with opening, makes things convenient for the shooting of video camera 30 and the projection of projector 20.
This video camera 30 is used to catch moving target (for example people's) video, and the video that captures is gathered via video frequency collection card 40, is sent to main frame 10.Each frame of 10 pairs of videos that collect of main frame carries out graphical analysis, calculates the action of moving target; Main frame 10 produces projected image according to the action of moving target then, and projects to ground, wall, ceiling, roof or pasted the on glass of projection film by projector 20, thereby realizes the effect of man-machine interaction.Compared with prior art, do not need to use laser pen to come identification signal, but the action of directly discerning moving target by the moving object detection technique produces drive signal, thus do not need use equipment can with the machine interaction, easy and simple to handle.In addition, need not to use screen prjection, but directly result of calculation is projected to occasions such as ground, wall, ceiling, the scope of application is more extensive.
This main frame 10 comprises Graphics Processing Unit 11, and (Graphics Processing Unit is GPU) with image analyzing unit 12.The video of being gathered by capture card 40 is sent in the main frame 10, by the image analyzing unit 12 of main frame 10 each frame is analyzed, and obtains the action of moving target and feeds back to the rendering module of Graphics Processing Unit 11; Calculate generation by finding the solution the 2D wave equation then, and use Graphics Processing Unit 11 to carry out speed-up computation, play up the figure that produces the 3D implementation result, reach the effect of man-machine interaction.
Utilize a scene of mutual optical projection system demonstration of the present utility model below, projector 20 projects to the figure (for example pond) of a width of cloth static state in certain zone, is caught the action of this regional moving target (for example Yan Shi people) then by video camera 30.When the human hand touches the pond, the action of stretching out one's hand that video camera 30 is caught the people, gather this video by capture card 40 then, be sent to the image analyzing unit 12 of main frame 10, image analyzing unit 12 analyses obtain the people and are stretching out one's hand the action that touches water, and action is fed back to the rendering module of Graphics Processing Unit 11, pattern process module carries out speed-up computation at once, the pond of calmness is depicted as the figure in the pond that produces ripple, make playing up of water reach the above 3D live effect that produces water of 30fps, project to this area of display by projector 20 again, realize the effect of human-computer interaction.
Understandable, video camera 30 also can not be the concrete action of catching moving target, and just moving target is carried out track and localization, after for example moving target arrives certain position, produce graph of a correspondence by main frame 10 at once, carry out projection, equally also can realize the effect of human-computer interaction.
