Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer,, and, the utility model is further described with reference to accompanying drawing below in conjunction with specific embodiment.
As shown in Figure 1, the structural representation of the screen prjection system that Fig. 1 provides for the utility model, this screen prjection system comprises main control equipment 1, projector equipment 2 and display device 3.
Wherein, main control equipment 1 is used to control projector equipment 2 the piecemeal video image is projected to display device 3, and block image is carried out audio video synchronization, splicing and fusion.Described main control equipment is equipped with at least one double end video card, and is connected with described projector equipment by described double end video card, and each bubble head of described double end video card connects a projector equipment.Described main control equipment be one can carry out video image synchronously, splicing and the computer equipment that merges, or one can carry out video image synchronously, splicing and the central processing unit (CPU) that merges.Described computer equipment or central processing unit carry out normal video synchronous in, make block image connect into continuous images by splicing from many projectors, and make adjacent block image realize the unification of brightness, thereby demonstrate complete image at display device by integration technology.
Projector equipment 2 is at least two, is used under the control of main control equipment 1 piecemeal video image synchronized projection to display device 3.Described projector equipment is a projector, or is projector.
Display device 3 is used for the video image of Display projector equipment projection.Described display device is a projection screen, and this projection screen is the sphere moulding, or is surface modeling, or is planar design.Described projection screen has the smooth and seamless surface, and this surface makes the projection proprietary material securely evenly attached to the outer field smooth and seamless of screen surface for adopting spraying method.
In Fig. 1, a main control equipment is installed simultaneously by two double end video cards, is respectively display card 10 and display card 11.Two bubble head 1-1 of display card 10 are connected projector equipment 2-1 and 2-2 respectively with 1-2, and two bubble head 1-3 of display card 11 are connected projector equipment 2-3 and 2-4 respectively with 1-4.Projector equipment 2-1,2-2,2-3 and 2-4 project video image on the projection screen 3 simultaneously.
Video image displayed all comes from the video file of storing in the main control equipment on many projector equipments, by audio video synchronization playout software module, has realized the synchronous playing of a plurality of videos.A plurality of video images form the image of given shape and certain luminance separately by after concatenation module and the Fusion Module, are sent to projector equipment 3 by display card then.
The splicing of video image and fusion realize by software systems that all implementation is as follows.
Shown in Fig. 2-1, the synoptic diagram before the image mosaic that Fig. 2-1 provides for the utility model.When projector equipment image projection to projector equipment 3 time, if the screen of projector equipment 3 is on-plane surfaces, then image will produce geometry deformation, for example the distortion shown in Fig. 2-1.What Fig. 2-1 showed is that two width of cloth projected images project the situation on the projection screen simultaneously.
Because this two width of cloth image is two adjacent in the big image, so need stitch together them.In the time of splicing, these two blocks of images need one and overlap the zone, prepare for image co-registration, and this point illustrates after a while.
We need be adjusted into the image that this two width of cloth has been out of shape respectively the rectangle of rule now, shown in Fig. 2-1, every width of cloth image all is made of some little rectangles, the summit of each little rectangle can be moved arbitrarily with mouse, therefore, can come the distortion of removal of images by the method for pointwise adjustment, shown in Fig. 2-1, the cursor of mouse is being adjusted a summit.
By the pointwise adjustment, can adjust to state shown in Fig. 2-2 to two width of cloth images, two width of cloth images intactly stitch together.Other two adjacent width of cloth images can splice in this way.Synoptic diagram behind the image mosaic that Fig. 2-2 provides for the utility model.
The fusion of video image realizes that by software systems implementation is as follows:
Shown in Fig. 3-1, the synoptic diagram before the image co-registration that Fig. 3-1 provides for the utility model.When two adjacent width of cloth images did not have intersection, the brightness of this two width of cloth image all was normal.Preamble is mentioned, through spliced two width of cloth images is to exist to overlap the zone, have two width of cloth projected images owing to overlap the zone, the brightness meeting produces stack, cause the situation of the brightness of intersection apparently higher than other parts, shown in Fig. 3-2, the synoptic diagram in the image co-registration process that Fig. 3-2 provides for the utility model.
At this moment, need adjust the brightness of image that overlaps the zone.Fusion Module can reduce to overlap the brightness value of each regional point, the value that reduces can be adjusted on the interface by mouse, like this, just can achieve the goal, reduce to overlap the brightness of regional image, two adjacent width of cloth images intactly are fused to together, form a continuous images, shown in Fig. 3-3, the synoptic diagram after the image co-registration that Fig. 3-3 provides for the utility model.Other two adjacent width of cloth images also can merge in this way, realize that all image sets synthesize the big image of a width of cloth.
As shown in Figure 4, the sectional view of the projection screen that provides for the utility model of Fig. 4.In the sectional view of projection screen as can be seen, the shape that projection screen itself 40 can be made screen with metal or nonmetallic material, after making, adopt the method for spraying to make projection proprietary material 41 in screen surface securely attached to screen surface, so just can make the surface of whole screen become projection screen, can present projected image clear, high brightness.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
