Chinese invention patent CN1448884A discloses a kind of chessboard recognition system based on vision, this system comprises chessboard, operating case, image card, PC, ccd video camera, support, light source, be provided with support in the chessboard sky, fix a ccd video camera by screw on the support and light source some, ccd video camera links to each other with PC by data cable, image card is housed in the PC, is provided with operating case on the chessboard right side.This system utilizes computer that the walking of traditional chessboard is discerned, and can not make up chessboard surface, and need utilize control box to control computer and video camera work, and structure is comparatively complicated.
Therefore, inventing a kind of cost virtual chessboard low, simple in structure becomes one problem to be solved is arranged.
The utility model content
The shortcoming that main purpose of the present utility model is to overcome prior art provides a kind of virtual chessboard that adopts projecting apparatus and image collecting device with not enough, and it has low, the advantage of simple structure of cost.
The purpose of this utility model realizes by following technical scheme: a kind of virtual chessboard that adopts projecting apparatus and image collecting device, comprise computer, image collecting device, projecting apparatus and projection screen, described image collecting device all is connected with computer by interface with projecting apparatus, projection screen is laid towards projecting apparatus and image collecting device, image collecting device is used for the image on the real-time acquired projections curtain and gives computer with image transfer, computer is used for system calibrating, judge the feature that chess piece identifies in the image according to the image that image collecting device is gathered, determine the actual screen coordinate of chess piece sign, on computer screen, make the action of playing chess, and the checkerboard image after will upgrading projects to projection screen.
Described image collecting device is connected with computer by USB or IEEE1394 interface.
Described image collector is changed to the visible light harvester that adopts CMOS or ccd sensor.
Described projecting apparatus is connected with computer by the VGA interface.
Described chess piece is designated monochromatic square or circular light spot or LED illuminating source hot spot, and its area is less than gridiron pattern area on the projection screen, and the different operating person uses the different chess piece sign of color.
Described image collecting device is laid towards projection screen, and its image that collects should be able to comprise whole projection screen.
Basic principle of the present utility model is: after the whole system installation, to carry out initialization to system when using first, chessboard surface on the labeling projection curtain, computer by projecting apparatus to projection screen projection chessboard uncalibrated image, image collecting device is gathered this image and is passed computer back, computer calculates the corresponding relation between projection screen chessboard and the screen chessboard, the coordinate at four angles of chessboard in the labeling projection curtain image.During the system commencement of commercial operation, the real-time acquired projections curtain of image collecting device image reaches computer, computer utilizes the color dividing method to obtain chess piece and is identified at position in the projection screen image, and calculate the actual coordinate of chess piece in chessboard of its representative according to its color characteristic, make the action of playing chess then, and upgrade checkerboard image and project on the projection screen, thereby realize the function of virtual chessboard.
The utility model compared with prior art has following advantage and beneficial effect:
1, the utility model adopts existing apparatus to realize the virtual chessboard function of giant-screen, need not existing apparatus is transformed, and relies on the video image process software that is installed on computer to realize interactive function.
2, image collector is changed to the general visible harvester and gets final product in the utility model, need not special configuration device, and cost is lower.
3, the utility model is installed simply, and the scene changes and only need carry out system initialization again when reinstalling and get final product.
