Description
Technical field
The invention belongs to stereo projection technology field, particularly a kind of fringe projection system.
Background technology
Traditional shadow casting technique can only realize two-dimensional effects, and spectators cannot perceive the three-dimensional information of object in screen, and tripleplane's technology of rising in recent years then changes this present situation.But current tripleplane needs beholder's wearing spectacles, bring constraint sense greatly and sense of discomfort to spectators; Although some high-end tripleplane's technology do not need viewers wear glasses, its cost of investment is implemented greatly, not easily; In addition, the projection screen in optical projection system is general comparatively large, and is fixed on ad-hoc location, not quick detachable and carrying, and making to project often can only be used for some fixing occasions, very flexible.
Summary of the invention
For background technology Problems existing, the invention provides a kind of fringe projection system.
For solving the problems of the technologies described above, the present invention adopts following technical scheme.
A kind of fringe projection system, comprises control system, projected array; Control system comprises stripping module, cutting module, memory module; Projected array comprises support, plural projected array unit, and projected array unit comprises carrier, projector, micromatic setting, original screen panel, and carrier is fixed on support, and micromatic setting is arranged in carrier, and projector is arranged on above micromatic setting; Original screen panel is arranged on carrier front by fixture; The original screen panel spliced in each projected array unit makes it to form projection screen.
The one side that described original screen panel is relative with projector is provided with matt film.
Described original screen panel is quadrangular plate, and two or more quadrilateral original screen panel is spliced to form ring curtain.
Described original screen panel shape triangular in shape, be spill in the middle of it, two or more spill triangular grating plate is spliced to form ball curtain.
Compared with prior art, the present invention has the following advantages and beneficial effect: structure of the present invention is simple, cost of investment is low, easy to implement; It is by realizing naked eye three-dimensional projection using original screen panel as projection screen, can need to build voluntarily, splice multiple difform original screen panel according to environment for use, original screen panel is made to form the difform screens such as flat curtain, ring curtain, ball curtain, be easy to dismounting and carrying, dirigibility is strong, be specially adapted to family, office or other small-sized places.

Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
The present invention includes control system, projected array; Control system comprises stripping module, cutting module, memory module; Projected array comprises support 7, plural projected array unit, projected array unit comprises carrier 1, projector 2, micromatic setting 3, original screen panel 6, carrier 1 is fixed on support 7, and micromatic setting 3 is arranged in carrier 1, and projector 2 is arranged on above micromatic setting 3; Original screen panel 6 is arranged on carrier 1 front by fixture 4; The original screen panel spliced in each projected array unit makes it to form projection screen 8; The one side that original screen panel is relative with projector is provided with matt film 5; Original screen panel is quadrangular plate, and two or more quadrilateral original screen panel is spliced to form ring curtain.
Control system is the core of whole optical projection system, for the conversion of video file before formal projection and the control to projector when formally projecting.Before projection, the transfer process of video file comprises: 1) video reads in; Before projection, read in by video file, video file is the video flowing that multi-angle is taken object, and angle can by two to eight not etc.2) video stripping; Every part of video file is processed frame by frame one by one, each two field picture is extracted from left to right in units of pixel and reconstructs, generate the video flowing being suitable for optical grating projection.3) cutting piecemeal; According to expectation total size of projected area and the design parameter of projector, determine the size of cutting, utilize the image processing function storehouse instruments such as opencv to step 2) the video file cutting frame by frame that process, piecemeal, and be respectively its distribution projector.4) store; Be stored as the video data that each projector distributes respectively.During projection, control system is connected to each projector, exports the video data of its correspondence to corresponding projector.
Projected array is arranged on by multiple projected array unit on the support that can splice arbitrarily and forms, and each projected array unit is an independently projection device.In projected array unit, the shape of original screen panel can select quadrilateral (as shown in Figure 1) or triangle as required, adopts quadrilateral original screen panel to can be used for building ordinary screen and ring curtain (as shown in Figure 3), adopts triangular grating plate to be used for building ball curtain.
Matt film in the present invention is by water-borne acrylic resin, water, porcelain earth, ethanol, formulated according to mass ratio 40:25:25:10.Add stirring machine after being merged by above-mentioned raw materials and carry out sand mill, each raw material is mixed, it is evenly coated in the original screen panel one side relative with spectators, according to projector light intensity with scraper, when the thickness of matt film is between 75-100um during coating, reach good drop shadow effect.This matt film has the effect of good elimination dazzle, can not experience the discomfort that high light brings when spectators watch projection.
Implementing process of the present invention is:
(1) setting support, fixing projector; Support is assembled by steel bar, after support is put up, carrier is fixed on corresponding position on support, then fixes projector, micromatic setting.(2) adjustment of projector; Because machinery has certain inexactness, certain deviation will inevitably be there is in the picture projected out, this carries out some fine settings to projector with regard to needs before projection, be the chequered with black and white striped of 1 pixel by projector to projection width on original screen panel screen, micromatic setting is utilized to carry out fine setting all around to the position of projector, the image that projector is launched just in time can completely cover screen time, black can be seen completely in screen side, and opposite side can see white completely.(3) projection is shown; Every platform projector is all connected to control system by data line, under control of the control system, complete image is launched by the screen that projected array unit just can build at original screen panel.
