Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Terminal device in the present invention comprises the terminal device that mobile phone, panel computer, notebook computer, desktop computer etc. have processing power.
The schematic diagram of the electronic paper marking method that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the electronic paper marking method of the embodiment of the present invention comprises:
Step 101, identify the display region information with the display information corresponding to the first file of lattice information, described display information is corresponding with the file data of described first file.
Particularly, terminal device identification has shape information, the displaying contents information of the viewing area of the display information corresponding to the first file of lattice information.
Wherein, the shape information of viewing area specifically comprises rectangle, circle etc.Displaying contents information specifically comprises objective item, subjective item etc.
Display information specifically comprises the information such as the word be presented on file, figure, and file data specifically comprises the back-end data corresponding with display information.
Wherein, dot matrix 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.First file specifically comprises the electronic document page of the student examination paper being loaded with lattice information.
Step 102, is divided into the sub-information of multiple display according to display region information by described display information, and the sub-information of described display is corresponding with the sub-file data in described file data, thus described file data is divided into file subdata.
Particularly, according to the shape information of viewing area, displaying contents information, display information is divided into the sub-information of multiple display, it is corresponding for showing sub-information with the sub-file data in file data, thus makes file data be divided into the file subdata of multiple correspondence.
Such as, divide according to the region at each exercise question place on paper, the back-end data of correspondence is divided equally.
Step 103, carries out regional code to the sub-information of described display, and gives threshold data, utilizes described regional code and threshold data composition threshold data table.
Particularly, because the first file has lattice information, after the display information of the first file is divided into the sub-information of multiple display, then the sub-information of each display also comprises lattice information.
If encoded according to region to the sub-information of display, the then lattice information of the corresponding certain area of coding region, subregion is carried out according to each exercise question, for each exercise question arranges score threshold data, then each regional code is to should the threshold data of region exercise question, obtains the threshold data table of regional code and threshold data composition.
Step 104, utilizes the dot matrix image data shown described in recognition device identification in sub-information, the regional code corresponding according to described dot matrix image data acquisition.
Particularly, utilizing recognition device identification to show dot matrix image data corresponding to sub-information, is lattice information by described dot matrix image Data Analysis, obtains corresponding regional code according to lattice information.
Dot matrix image data in sub-information are shown utilizing recognition device identification, according to before the regional code that dot matrix image data acquisition is corresponding, need the file ID of identification first file, file ID is specially the identification information of student, after identifying the identity of student, could confirm that this paper is the test paper of which student.
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.
When the pressure transducer of dot matrix digital pen detects pressure signal, start camera, taken pictures in the dot matrix region of nib process, packet is generated after sending to processor to be converted to digital signal, terminal device is sent to process in real time by the data-interface of communication module, or memory stores data bag, timed sending is to terminal device.Recognition device is associated with terminal device by unique ID code.After terminal device receives packet, extract the ID code in packet header, after empirical tests, if be legal or registered, then resolution data bag, otherwise prompting warning message.
Wherein, 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 105, utilizes described regional code to inquire about described threshold data table, obtains corresponding threshold data.
Particularly, according to regional code inquiry threshold data table, the mark pre-set of exercise question corresponding to this region is obtained.
Such as, in the regional code " 5 " of the paper of examinee " Zhang San " corresponding " calculation question the 1st topic ", the full marks of this exercise question are 5 points.
Step 106, when described view data is identified as the first symbol, increases corresponding threshold data.
Particularly, when the dot array data of image data analyzing is identified as " √ ", be then that the exercise question in this region increases corresponding mark, now, the first symbol is specially " √ ".
When the dot array data of image data analyzing is identified as "×", then do not increase mark corresponding to this region exercise question, now, the second symbol is specially "×".
When the dot array data of image data analyzing is identified as " 3 ", then for the exercise question in this region increases by 3 points, now, the second symbol is specially " 3 ".
When the dot array data of image data analyzing is identified as "-2 ", then for the exercise question in this region deducts 2 points, now, the second symbol is specially "-2 ".If these exercise question full marks are " 5 points ", then final score is 3 points.
Finally, after the score of each exercise question being gathered, the total score of this student is obtained.
The electronic paper marking method that the embodiment of the present application provides, utilizes dot matrix recognition technology, realizes written handwriting electronization, divides after going over examination papers from kinetonucleus, and identify that mark accuracy rate is high, method realizes simple, substantially increases work efficiency.
