Abstract

The invention provides an interactive display system. The system comprises a computer, an image projector and a projection screen. The system further comprises a display control device, and the display control device comprises a storage unit, an image acquisition unit and a processing unit, wherein the storage unit is used for storing a shadow gesture-control action table, and each shadow gesture in the table corresponds to a control action; the image acquisition unit is used for periodically acquiring an image displayed on the projection screen; and the processing unit is used for continuously receiving and processing the acquired image so as to determine whether the currently acquired image contains the shadow gesture or not, as well as determining the type of the shadow gesture when determining that the currently acquired image contains the shadow gesture, determining the corresponding control action according to the action table, producing a corresponding control command and sending the control command to a computer. The use of the display control device can lead an operator to make the gesture corresponding to the control action which needs to be implemented currently in the projection image of the image projector and control the image display on the projection screen.

Description

Interactive display system
Technical field
The present invention relates to a kind of display system that adopts computing machine, computer-controlled image projector and projection screen, particularly a kind of interactive display system, the image of wherein controlling on the projection screen is to realize by the gesture that projects on the projection screen.
Background technology
Chart, literal and various pattern pass through usually these image optics are projected on projection screen or the wall in meeting and classroom and are shown to spectators.LCD (liquid crystal display) projector is often used as image source, and wherein chart, writings and image are produced by computing machine.When using conventional LCD/ computer projection display system, operating personnel need get back to the other operational computations machine of computing machine with the image on the control projection screen, or are sitting in the other support personnel's operational computations machine of computing machine with the image on the control projection screen.No matter be that operating personnel or support personnel's operational computations machine are controlled the image on the projection screen, all can influence exchanging of operating personnel's explanation and operating personnel and spectators.
Summary of the invention
In view of this, the invention provides a kind of exchange display system by shadow gesture control projected picture.
Described interactive display system comprises computing machine, image projector and projection screen, and the image that described computer run computer software produces projects on the described projection screen via described image projector.Described interactive display system also comprises display control unit, and described display control unit comprises: cell stores shadow gesture-control command table, and in described shadow gesture-control command table, the corresponding control action of each shadow gesture; Image acquisition unit is used for periodically gathering the image that shows on the described projection screen; And processing unit is used for receiving continuously the image that described image acquisition unit is gathered, the image that receives is carried out Flame Image Process, whether to comprise the shadow gesture in the image of determining the current collection of described image acquisition unit, described processing unit also is used for when the image of determining the current collection of described image acquisition unit comprises the shadow gesture, determine the type of described shadow gesture, and determine and described definite corresponding control action of shadow gesture according to described shadow gesture-control action table, and generation and described definite corresponding discernible control command of described computing machine of control action, and the control command of described generation sent to described computing machine.
Use described display control unit, the operator makes the gesture of the control action correspondence of current desire execution in image projector drop shadow spread, and the image that then can control easily on the projection screen shows.

Embodiment
Please refer to Fig. 1, interactive display system 100 comprises computing machine 10, image projector 20, projection screen 30 and display control unit 40.In the operating process of display system 100, computing machine 10 operation software for calculation are as Microsoft
Figure BDA0000027176220000021
The image that produces projects on the projection screen 30 via image projector 20.
Display control unit 40 comprises storage unit 42, image acquisition unit 44, processing unit 46 and communication unit 48.Display control unit 40 communicates by communication unit 48 and computing machine 10.Communication unit 48 can be wire communication unit or wireless communication unit.
Storage unit 42 stores shadow gesture-control action table (calling action schedule in the following text).In action schedule, the corresponding control action of each shadow gesture.The shadow gesture comprises that singlehanded shadow, both hands separate shadow, both hands intersection shadow etc.Control action comprises page turning forward, page turning, jump page etc. backward.
Shadow gesture-control action table
The shadow gesture Control action
The first shadow gesture First control action
The second shadow gesture Second control action
...... ......
Image acquisition unit 44 is used for the image that shows on the acquired projections screen 30 periodically.Projection screen 30 is positioned at the image pickup scope of image acquisition unit 44.Processing unit 46 receives the image that image acquisition unit 44 is gathered continuously, and the image that receives is carried out Flame Image Process, whether to comprise the shadow gesture in the image of determining current collection.When processing unit 46 also comprises the shadow gesture in the image of determining current collection, determine the type of described shadow gesture, and determine and the corresponding control action of described shadow gesture according to control table, and the generation computing machine 10 discernible control commands corresponding, and the control command that produces sent to computing machine 10 by communication unit 48 with described control action.Computing machine 10 is carried out the control corresponding action according to the control command that produces, and shows with the image on the control projection screen 30.
In order to understand the present invention better, control procedure of the present invention is described below in conjunction with Fig. 3 A-3C.Setting projects to the control action of the singlehanded shadow correspondence " page turning backward " of projection screen 30.Among Fig. 3 A, projection screen 30 shows first picture.Among Fig. 3 B, operator's a hand projects to and forms singlehanded shadow on the projection screen 30.The current shadow gesture of processing unit 46 identifications is singlehanded shadow, thereby determines that the control action that the current desire of operator is carried out is " page turning backward ", produces and send the control command corresponding with the control action of " page turning backward " then to computing machine 10.The content of following one page is transferred and shown to the described control command of computing machine 10 identifications, thereby correspondingly show the content (shown in Fig. 3 C) of one page down on the projection screen 30.
In the present invention, the operator makes the gesture of the control action correspondence of current desire execution in image projector 20 drop shadow spreads, and the image that then can control easily on the projection screen 30 shows.
