Abstract
The invention discloses a gesture-based PPT (Power Point) control system which comprises an image acquiring module for acquiring an external gesture image and sending the external gesture image to a gesture processing module; the gesture processing module for processing the external gesture image received and comparing the processed gesture image with gesture image list information stored locally to send a corresponding control command to a command output module; the command output module for sending the control command received to a processor to control a PPT. With the application of the system in the PPT demonstrating process, users are released from a keyboard, a mouse and a remote controller and can control freely in the demonstrating process, so that the demonstrating controllability and smoothness are improved.
Description
Technical field
Teaching demonstration control field, particularly a kind of PPT control system based on gesture the present invention relates to handle official business.
Background technology
In teaching lecture system or meeting report system, the e-teaching plan and the technical report that use PowerPoint to make, major part still has line traffic control by original mouse, keyboard, it is the interaction that teaching method or meeting report are all paid attention to operating personnel and spectators, when going down the dais, operating personnel exchange with spectators when running into PPT and needing the situation of page turning, have to again to interrupt and the exchanging of spectators, again walk back the dais and carry out the PPT page turning.Wired connection has fettered people's scope of activities, has brought a lot of inconvenience to real life.
Chinese patent application number is that 200610011999.5 application for a patent for invention discloses a kind of based on the intelligent mobile phone platform method for remote controlling computer, its main technical schemes is: all possess in the situation of J2ME development platform at mobile phone and computing machine, mobile phone terminal uses WAP by mobile phone screen and keyboard the computing machine memory to be controlled the inconvenience that the effect the method that reaches control PPT has overcome appeal to a certain extent, but the technical scheme of this invention is owing to adopt WAP to carry out network connection, there is certain delay, and the control by mobile phone is equivalent to control by telepilot, does not remove the constraint of the similar actuation means such as telepilot.
Summary of the invention
The technical matters that (one) will solve
The technical problem to be solved in the present invention is:
In the PPT presentation process, can only control PowerPoint PPT by similar control devices such as keyboard, mouse or telepilots, can't realize convenient and swift and need not the operation of external device.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides a kind of PPT control system based on gesture, this system comprises:
Image collection module is used for obtaining extraneous images of gestures, and extraneous images of gestures is sent to the gesture processing module;
The gesture processing module, for the treatment of the extraneous images of gestures that receives, and the images of gestures list information of the images of gestures after will processing and local storage compares, and the steering order of correspondence is sent to the instruction output module;
The instruction output module, the steering order that is used for receiving sends to processor, finishes PPT is controlled.
Described image collection module realizes that by depth camera the degree of freedom of described depth camera is ± 27 degree.
Described gesture processing module specifically comprises:
Video processing unit is used for the image that image collection module sends is processed, and removes background image, obtains the hand exercise image;
The staff information process unit is used for the hand moving image is processed, and obtains the gesture motion track;
The feature generation unit is used for the gesture motion track is processed, and its dress is changed to gesture feature information;
Data are preserved and recognition unit, are used for that described gesture feature information and date is preserved the steering order information of storing with recognition unit and compare, and send to the instruction output module by the steering order of correspondence.
Described gesture processing module also comprises:
Training and recognition unit are used for training and learning gesture sample, and described gesture sample information are added in the steering order information of data preservation and recognition unit.
Described gesture comprises that singlehanded gesture and both hands cooperate gesture.
Described steering order comprises: slideshow, finish projection, page turning, paintbrush and withdraw from paintbrush.
Described depth camera towards with projector towards identical.
(3) beneficial effect
Control by in the PPT presentation process, using gesture, so that the user has broken away from the constraint of keyboard, mouse and telepilot, can in presentation process, freely control, improved the controlled and fluency of demonstration.
Description of drawings
Fig. 1 is the process flow diagram of a kind of PPT control system based on gesture of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1,
In the PPT presentation process, image collection module adopts depth camera that effector's gesture is obtained, and the degree of freedom of depth camera be ± 27 to spend, with projector towards identical.By depth camera motion capture being carried out in effector's action, is the constraint that the effector breaks away from the devices such as keyboard, mouse and telepilot, and does not dynamically do accurately, has improved the controlled and fluency of demonstration.
Depth camera sends to the gesture processing module with image information, the image that video processing unit sends image collection module in the gesture processing module is processed, remove background image, obtain the hand exercise image, and the hand exercise image is sent to the staff information process unit.
The staff information process unit is processed the hand exercise image that receives, and obtains the gesture motion track, and the gesture motion track is sent to the feature generation unit.
The feature generation unit is processed the gesture motion track that receives, and its dress is changed to gesture feature information, and gesture feature information is sent to data preservation and reading unit.
Data preserve with recognition unit with the gesture feature information and date that receives preserve with reading unit in the steering order information of storing compare, send to the instruction output module by the steering order of correspondence.
Steering order information is as shown in the table
Control gesture in the control procedure comprises that singlehanded gesture and both hands cooperate gesture, and steering order comprises slideshow, finishes projection, page turning etc.
The gesture processing module also comprises training and recognition unit, is used for training and learning gesture sample, and described gesture sample information is added in the steering order information of data preservation and recognition unit.Be more convenient for Management and application to control information by training and recognition unit.
Gesture information is finished dealing with rear system by the instruction output module, the steering order that receives is sent to processor PPT is controlled, and utilize the LCD liquid crystal projector to carry out output display.
Need not the operator by the PPT control system based on gesture and wear any designation equipment, only need by obtaining the gesture depth image, just can obtain steering order, improved the controlled and fluency of demonstration.
Above embodiment only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; in the situation that does not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
