Description of drawings
Fig. 1 is the structural representation of intelligent teacher's pointer.
Fig. 2 is teacher's pointer body of rod internal control circuit plate module structural representation.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, the present invention's intelligence teacher's pointer comprises the teacher's pointer body of rod, the indication end of the body of rod is provided with laser pen 1 and camera 2, the handheld terminal of the body of rod be provided with the electronic whiteboard control knob (turn over before the blank and after turn over button 3,4), people's face detects recognition button 5, identity information the Show Button 6 and laser pen instruction button 7, rod body part is provided with control circuit board 8, integrated laser pen controller, camera controller, electronic whiteboard controller, recognition of face Single Chip Microcomputer (SCM) system and battery pack system on the control circuit board, the surface of the body of rod is embedded with liquid crystal micro display screen 9.
Be the synoptic diagram of control circuit board among Fig. 2, be described as follows.
1, the laser pen controller is an independent circuit module, receives the button level signal, and the emission of control laser or close.The present invention reequips existing laser pen, and the contact switch of laser pen has been carried out suitable bias treatment, has been placed on the handle place.
2, the camera controller is exactly a simple FET switch circuit in fact, in order to control the Kai Heguan of camera.Main and external shift knob links to each other with camera, and acceptor's face detection recognition button level signal, with startup camera collection facial image, and triggers Single Chip Microcomputer (SCM) system the video information of camera collection is carried out analyzing and processing.
3, the electronic whiteboard controller also is an independent module, is used for the page turning of long-distance remote control blank.The circuit board of electronic whiteboard controller repacking in the infrared remote control keyboard among the present invention, for example integrated chip PT2248.Be integrated with infrared transmission module, corresponding, its infrared receiving module that is installed in the electronic whiteboard computer terminal is also essential.Its principle of work is that the electronic whiteboard controller receives the triggering level signal from the blank page turning control knob of being located at the handle place, triggers infrared transmission module, and the computer system of connecting electronic blank is controlled, and achieves page-turning function.
4, recognition of face Single Chip Microcomputer (SCM) system is in order to catching people's face, and identifies its identity information.The recognition of face Single Chip Microcomputer (SCM) system outreaches the liquid crystal micro display screen, inline camera controller.When people's face detection recognition button is pressed, Single Chip Microcomputer (SCM) system begins the facial image that carries out the video camera shooting is processed, at first people's face is positioned and cut apart, then identify, the student information database that use prestores compares to gathering image, determine pupilage information, and under the control of identity information the Show Button, this image and corresponding identity information are outputed on the liquid crystal micro display screen.Demonstration can be the independent demonstration of identity information, also can be overlapping demonstration, marks such as the next door on image.Single Chip Microcomputer (SCM) system has a lot of implementations, uses dsp program if any using the AT89C51 single-chip microcomputer, having.Example of the present invention is taked be the ARM9 series S3C2410 of Samsung as processor, frequency of operation can reach 203MHz, can satisfy system to the requirement of computing velocity.Built-in 2 USBHOST of this processor can be used to connect the USB camera.User-friendly so comparatively general and cheap camera change system.
People's face in the face identification system detects and localization method has much in the literature, roughly is divided into by color characteristic, by morphological feature, Model Matching etc.The present invention mainly determines people's face position by human eye detection and dynamic video analysis.
Face identification method in the face identification system can adopt following a few class:
Face identification method based on geometric properties.Geometric properties commonly used has the local shape feature of the face of people's face such as eyes, nose, face etc. and the geometric properties of overall distribution.But this category feature is not very stable, and robustness is very poor when expression shape change, attitude variation;
The method of subspace-based.That adopt the earliest is principal component analysis (PCA) PCA, and comparatively successful method was linear discriminant analysis LDA afterwards, and was insensitive to illumination, expression etc. comparatively speaking;
Method based on statistics.These class methods have hidden Markov model HMM, support vector machines, neural network, elastic graph coupling, AdaBoost, LBP(local binary patterns) etc.
The system of recognition of face has: based on the system of camera, optical camera; Recognition of face based on 3-D view; Recognition of face based on thermal imaging; Recognition of face based near infrared (NIR) image.
Example of the present invention is integrated based on the face recognition algorithms of local binary patterns LBP with based on the system of camera.
Integrated circuit plate and corresponding peripheral hardware are all accepted the power supply of battery pack system.
Those skilled in the art will readily understand; the above only is preferred embodiment of the present invention; not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
