Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Terminal in the present invention comprises the terminal device that mobile phone, panel computer, notebook computer, desktop computer etc. have processing power.Recognition device is the dot matrix digital pen with dot matrix recognition function, is built-in with pressure transducer, processor, camera, storer and communication module etc.
The process flow diagram of the dot matrix recognition methods that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the dot matrix recognition methods of the embodiment of the present invention comprises:
Step 101, recognition device is associated with terminal by unique ID code.
Particularly, recognition device sends login request message to terminal, and login request message comprises unique ID code, after terminal receives request message, is registered by the ID code that recognition device sends, sends response message after succeeding in registration.
Wherein, the sequence number etc. that ID code is specially recognition device uniquely can confirm the information of recognition device.
Step 102, when pressure signal being detected, judge whether described force value is greater than default first threshold, if, then gather the dot matrix image data in the dot matrix region that described recognition device moves across in the current pressure values duration, generate Packet Generation to terminal.
Particularly, when recognition device moves on the carrier of unlike material with dot pattern, such as paper, blank, electronic display etc., preset different threshold values, current pressure values is greater than default threshold value for the moment, in the duration section of current pressure values, recognition device is by the dot matrix image data in the dot matrix region of built-in camera collection process, and the processor sending to recognition device built-in; After dot matrix image data are converted to digital signal by processor, after adding timestamp, generate packet; After the packet header of packet being added the ID code of recognition device, send to terminal by data-interface.
Wherein, dot matrix region is made up of several points, according to the regularly arranged composition of particular algorithm, as shown in Figure 2.Such as, every 36 points, permutation and combination becomes a dot matrix.Mean distance between 2 is 0.3mm.The size of each dot matrix is 1.8mm × 1.8mm.Dot matrix, by special coded system, represents special co-ordinate position information.After each coding in dot matrix, obtain dot matrix coded sequence, as shown in Figure 3.Camera is high-speed camera head, can with the speed of 100 per second to harvester the dot matrix of process take pictures.
Data-interface is wired data interface or wireless data interface; Wired data interface is specially USB interface, MiniUSB interface, MicroUSB interface, parallel port, serial ports; Wireless data interface is specially blue tooth interface, infrared interface, Wifi interface, 2.4-5.0GHz wave band interface or wireless communication interface.
Step 103, described terminal extracts the ID code of described packet header, judges that whether described ID code is legal, if so, then resolves described packet, obtain view data.
Particularly, after terminal receives the data of recognition device transmission, extract the ID code of packet header, and whether the ID code of verification msg handbag head is legal, or whether be registered ID code, if legal or registered, then packet is resolved, the ID code obtaining dot matrix image data, gather the temporal information of dot matrix image, gather the page of dot matrix image data; If ID code is illegal, or without registration, then point out warning message.
Step 104, carries out identifying processing by described view data, obtain described recognition device the identifying information in dot matrix region of process.
Particularly, view data is carried out identifying processing, obtain coordinate or the coding of the dot matrix that recognition device moves across according to time series, thus obtain movement locus, utilize display device to show movement locus.
In addition, can arrange feature capability icon in dot matrix region, function comprises: record/continue, suspend, preserve, all erasings, person's handwriting-thin, person's handwriting-in, person's handwriting-thick, self-defined person's handwriting color, page up, lower one page etc.
When the view data corresponding function icon that recognition device collects, view data is identified as function information, terminal performs corresponding function event according to function information.
The dot matrix recognition methods that the embodiment of the present application provides, gathers dot matrix image data by recognition device, sends to terminal, obtain identifying information after terminal processes, and method realizes simple, and without interruption, accuracy of identification is high.
