Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a flowchart of a method for generating a composite encoded file according to an embodiment of the present invention includes the following steps:
step S101, acquiring a pre-coded original file and additional information of the original file.
Specifically, the original file is a courseware, a test paper, an electronic book, or the like containing content. Preferably, the original file is a standardized format file, for example, with a page size of a4, A3, B5, etc., and the file format is a printable or printed file of pdf, word, jpg, etc. For non-standardized format files, format conversion is performed first, and then coding is performed after the non-standardized format files are converted into standard format files.
The additional information of the original file includes at least index information of the original file, which can be used to uniquely determine the original file, such as a file ID of the original file. According to actual requirements, the user ID of the original file, factory information of the original file and the like can be included.
Step S102, determining a first coding resource for coding the identification area of the original file according to the original file.
The first coding resource carries coordinate information and is a dot matrix graphic resource adopting special coding. The identified area of the original file is the area that covers the content of the original file and/or needs to be written, and the size and position of the area can be specified by the user. The lattice resource is composed of a plurality of very fine points which are regularly arranged according to a special algorithm. The dot matrix has the function of providing the dot matrix identification device with coordinate parameter information, and the dot matrix identification device can accurately record the motion track when moving in dot matrix resources. Specifically, the dot matrix identification device is an intelligent pen. The lattice resource is composed of a plurality of lattice units, each of which is composed of a plurality of dots, and fig. 2 is a schematic diagram of a lattice unit corresponding to the first coding resource according to the embodiment of the present invention. The lattice unit comprises 4 x 4 virtual squares, and each virtual square consists of four lattice points and 1 information point surrounded by four lattice points. Each dot matrix unit comprises 16 information points, each information point has eight different deviation positions of upper, lower, left, right, upper left, lower left and upper right, and the 16 points have 8 16 power arrangement modes, namely 281 trillion arrangement modes. Assuming that the distance between the virtual squares of each lattice unit is 0.5mm, the size of each lattice unit is 2mm × 2 mm. I.e. the entire lattice resource can cover 2.81 x 4 hundred million square meters. The lattice coding modes are various, and the corresponding arrangement types of different lattice coding modes are different. For example, the dot-matrix coding scheme adopted by Anoto corporation includes 36 information dots per dot-matrix unit, each information dot includes 4 offset positions, and the total number of the information dots is 47 trillion arrangement forms.
Preferably, the determining, according to the original file, a first coding resource for coding the identification area of the original file specifically includes:
acquiring page layout information and page number information of an original file;
and calculating the area/page number of the first coding resource required for coding all the identification areas of the original file according to the page layout information and the page number information.
Specifically, an original file may contain several pages, the apparatus of the present invention may encode all or part of the specified pages, and further, the apparatus of the present invention obtains page layout information of the original file, that is, the size of each page encoding region. Typically, the apparatus of the present invention encodes the entire page area by default. The area/page number of the required dot matrix resource can be calculated by acquiring the page layout information and the page number information of the original file, namely, the area/page number of the first coding resource required for coding all the identification areas of the original file is determined.
Preferably, before acquiring the page layout information and the page number information of the original file, the method further includes:
acquiring user attribute information and/or file attribute information of the original file;
and determining a code segment of a first coding resource for coding the identification area of the original file according to the user attribute information and/or the file attribute information.
As mentioned above, a lattice resource can be regarded as a huge piece of paper, and preferably, the lattice resource is allocated according to user attributes and/or file attributes, and specifically, a first encoding resource of a certain code segment range is allocated to a user of a certain user attribute and/or a file of a certain file attribute. The user attributes comprise schools, organizations, individuals and the like, and the file attributes comprise file types, page sizes and the like. Specifically, different lattice resources are allocated to different schools or the same lattice resource is allocated to different schools. Because the files generated among different schools cannot be used in a cross mode, the multiplexing of a plurality of schools can be realized by using the same dot matrix resource, and therefore the use of the dot matrix resource is greatly saved. Further, the user attributes also include a grade, a class, a subject, and the like. Alternatively, different grades, classes and subjects may share the same dot matrix resource and be distinguished by using ID on the dot matrix identification device. Therefore, lattice resources can be saved, because the classes do not carry out cross lecture and cross use files, and because the lattice identification device is distinguished, the multiplexing of the lattice resources can be realized between the classes. Preferably, the apparatus of the present invention is further configured to allocate the first encoding resource according to the file attribute information, for example, allocate different code segments according to different file types or page sizes, wherein the file types include test paper, courseware, electronic book, etc., and the page sizes include a4, B5, A3, etc. Preferably, all the lattice resources are stored in a database, and the user accesses and acquires the required lattice resources by using the user ID.
Step S103, determining a second coding resource for coding the additional information area of the original file according to the additional information of the original file.
The second coding resource carries code information corresponding to the additional information, and is also a dot matrix graphic resource adopting special coding. Specifically, the code information may be carried by one lattice unit or several lattice units together.
Determining, according to the additional information of the original file, a second encoding resource for encoding the additional information region of the original file specifically includes:
determining code information required to be carried by the second coding resource according to the additional information of the original file;
generating a basic coding unit by using the code information required to be carried by the second coding resource according to a preset coding rule of the second coding resource;
and calculating second coding resources required by repeatedly laying the basic coding units in the additional information area of the original file according to the size of the additional information area of the original file.
Fig. 3 is a schematic diagram of a lattice unit corresponding to a second coding resource according to an embodiment of the present invention. The dot matrix unit 10 includes a code information portion 12 and a table header portion 14. The code information portion 12 includes 9 dots 16 and 9 status areas 18 where the 9 dots 16 are located, and the headtable portion 14 includes 7 dots 16 and 7 status areas where the 7 dots 16 are located, and the whole forms a4 × 4 dot matrix unit. The 9 information dots 16 may have 4 offset positions of upper left, lower left, upper right, and lower right so that they can carry 18-bit data, and the 7 header dots 16 may be designed with 4 offset positions of upper, lower, left, and right bits. The header 14 surrounds the upper left of the code information portion 12 and forms an L-shaped structure, and dots 16' are used to identify the direction of the dot matrix unit. The header 14 is used to distinguish two adjacent dot matrix units, and the dot matrix units 10 having the same code information portion 12 also have the same header 14. Thus, the same lattice unit can be found by looking up the table header 14.
How to encode the additional information using the lattice unit shown in fig. 3 is described in detail below. For example, the additional information is a file ID (9ae43001) of an 8-bit 16-ary number, and for simplicity, the corresponding code information is 32 bits in total, which is a binary number directly converted from the 16-ary number, that is, 10011010111001000011000000000001. Assuming that the lattice unit of fig. 3 is used to encode it, since each lattice unit in fig. 3 can carry only 18 bits of information, 2 lattice units are required to carry 32 bits of information. Therefore, it is necessary to design 2 types of headers, and one basic coding unit is integrally represented by 2 dot matrix units. Fig. 4 is a schematic diagram of a basic coding unit corresponding to a second coding resource provided in an embodiment of the present invention. Different from the first coding resource, the second coding resource is formed by repeatedly laying the basic coding units in the additional information area of the original file, so that the dot matrix identification device can accurately acquire the code information carried by the second coding resource when the dot matrix identification device fetches the additional information area. Further, according to the size of the additional information area of the original file and the size of the basic coding unit, the number (including the horizontal number and the vertical number) required for repeatedly laying the basic coding unit in the additional information area of the original file is calculated, and the number of the basic coding unit is the required second coding resource.
It should be noted that, the encoding manner of the second encoding resource is not limited in the present invention, and fig. 3 and fig. 4 are only used to illustrate how to generate the code information to the encoding graph, and further determine the encoding resource required for encoding the additional information area by the encoding graph. Other encoding schemes can be designed to encode the code information according to common knowledge of the skilled person.
And step S104, loading the first coding resource to the identification area of the original file, and loading the second coding resource to the additional information area of the original file to generate a composite coding file.
Loading the first coding resource in the identification area of the original file, actually assigning the dot matrix code information in the identification area of the original file, and establishing the corresponding relation between the dot matrix resource and the original file in position. And loading the second coding resource to the additional information area of the original file so as to establish the corresponding relation between the paper coding file and the original file. After the generated composite coded file is printed or projected and displayed, when the dot matrix recognition device clicks in an additional information area of the paper coded file, the corresponding original file can be obtained, when the dot matrix recognition device moves in the recognition area of the composite coded file, the motion track data of the dot matrix recognition device can be obtained, the motion track data is sent to a computer or a mobile terminal in real time, and the computer or the mobile terminal displays the recognition track on the corresponding position of the composite coded file according to the corresponding relation of the dot matrix resources and the original file on the position, so that the writing handwriting can be directly stored in the computer in real time, and the digital storage and display of the writing handwriting are realized.
Preferably, the additional information area of the original document is located in the original document cover or in the area around the page that does not affect the display of the document content. FIG. 5 is a schematic diagram of a page of a compound encoded file according to an embodiment of the present invention, wherein an additional information area is located below the page.
In the embodiment of the invention, the identification area of the original file is coded by adopting the coding resource carrying the coordinate information, and the additional information area of the original file is coded by adopting the coding resource carrying the code information, so that the composite coding file is generated. After the composite encoded file is projected or printed, the corresponding original file information can be obtained by clicking the additional information area of the file through the dot matrix identification device, the dot matrix identification device is further used for writing on the composite encoded file, the motion track of the dot matrix identification device on the file can be accurately obtained, and the writing notes on the file are digitally stored and reproduced in real time.
In an embodiment of the present invention, a composite encoded paper document is further provided, where an identification area of the composite encoded paper document is encoded by using a first encoding resource, and the first encoding resource is a dot matrix resource carrying coordinate information; and the additional information area of the composite coding paper file is coded by adopting a second coding resource, and the second coding resource carries index information of the electronic file corresponding to the composite coding paper file.
Specifically, the composite encoded paper document is printed or stamped according to the composite encoded document generated by the method for generating a composite encoded document according to the embodiment of fig. 1. The additional information area of the composite coding paper document is positioned in the envelope or the area around the page which does not influence the display of the document content.

an obtaining module 61, configured to obtain a pre-encoded original file and additional information of the original file;
a first determining module 62, configured to determine, according to the original file, a first coding resource for coding an identification area of the original file, where the first coding resource carries coordinate information;

The header 14 is used to distinguish two adjacent dot matrix units, and the dot matrix units 10 having the same code information portion 12 also have the same header 14. Thus, the same lattice unit can be found by looking up the table header 14.
How to encode the additional information using the lattice unit shown in fig. 3 is described in detail below. For example, the additional information is a file ID (9ae43001) of an 8-bit 16-ary number, and for simplicity, the corresponding code information is 32 bits in total, which is a binary number directly converted from the 16-ary number, that is, 10011010111001000011000000000001. Assuming that the lattice unit of fig. 3 is used to encode it, since each lattice unit in fig. 3 can carry only 18 bits of information, 2 lattice units are required to carry 32 bits of information. Therefore, it is necessary to design 2 types of headers, and one basic coding unit is integrally represented by 2 dot matrix units. Fig. 4 is a schematic diagram of a basic coding unit corresponding to a second coding resource provided in an embodiment of the present invention. Different from the first coding resource, the second coding resource is formed by repeatedly laying the basic coding units in the additional information area of the original file, so that the dot matrix identification device can accurately acquire the code information carried by the second coding resource when the dot matrix identification device fetches the additional information area. Further, according to the size of the additional information area of the original file and the size of the basic coding unit, the number (including the horizontal number and the vertical number) required for repeatedly laying the basic coding unit in the additional information area of the original file is calculated, and the number of the basic coding unit is the required second coding resource.
It should be noted that, the encoding manner of the second encoding resource is not limited in the present invention, and fig. 3 and fig. 4 are only used to illustrate how to generate the code information to the encoding graph, and further determine the encoding resource required for encoding the additional information area by the encoding graph. Other encoding schemes can be designed to encode the code information according to common knowledge of the skilled person.
Loading the first coding resource in the identification area of the original file, actually assigning the dot matrix code information in the identification area of the original file, and establishing the corresponding relation between the dot matrix resource and the original file in position. And loading the second coding resource to the additional information area of the original file so as to establish the corresponding relation between the paper coding file and the original file. After the generated composite coded file is printed or projected and displayed, when the dot matrix recognition device clicks in an additional information area of the paper coded file, the corresponding original file can be obtained, when the dot matrix recognition device moves in the recognition area of the composite coded file, the motion track data of the dot matrix recognition device can be obtained, the motion track data is sent to a computer or a mobile terminal in real time, and the computer or the mobile terminal displays the recognition track on the corresponding position of the composite coded file according to the corresponding relation of the dot matrix resources and the original file on the position, so that the writing handwriting can be directly stored in the computer in real time, and the digital storage and display of the writing handwriting are realized.
