Description

Signboard Production Ordering System

The present invention relates to a sign production ordering system. More specifically, in order to request a sign quote and place an order, the orderer accesses the sign production server through a terminal and enters text along with the type, standard, etc. of the sign. It is a system that converts a two-dimensional (2D) font into a three-dimensional (3D) font and displays it by applying it to a designated type of sign. Rather than using a 3D font with a large capacity load as input data, a 2D font with a small capacity load is used as input data. A database is built in advance using the font as input data, and then the outline data of the 3D font corresponding to the input 2D text is extracted and the 2D font is converted into a 3D font in real time to display a three-dimensional image of the sign. It is about a sign production ordering system that is fast, accurate, and requires little memory by preventing excessive computer capacity, long time consumption, and frequent errors and bugs caused by the conversion process.

In the case of producing outdoor signs to be installed in stores, etc., recently, the convenience of ordering by accessing the sign production company's system online through the network has gradually expanded. In this case, a client who wants to produce a sign can access the sign production company's system. By entering the type, size, and text of the signboard you wish to order, the production system displays the text and form of the content desired by the client through the online ordering screen and visually presents it to the client. do.

If the client likes the shape of the sign displayed above, he or she will place an order through the system, and a contract will be concluded between the client and the production company, leading to the process of producing the sign and paying the price.

At this time, in order for the client, that is, the orderer, to make a correct choice online, it is necessary to clearly understand the appearance of an example of a signboard production. For example, the two-dimensional appearance of the signboard shown online may be different from the three-dimensional shape of the signboard actually installed on site. In this case, the cost and time involved in producing the sign are not only wasted, but also the expected effect of the sign is reduced, so it becomes difficult to make a decision to make a sign without seeing the actual sign in person when it is actually completed.

Accordingly, when the orderer selects the type and pattern of the sign through the terminal, the sign manufacturing company converts the selected type and pattern into 3D, sees the shape of the actual sign in three dimensions, seeks understanding of the actual product, and makes accurate orders and decisions. We can support you to do so.

However, in this case, in the task of converting a pattern entered in two dimensions (2D) into three dimensions (3D), the program for converting two dimensions to three dimensions is based on English text, while the program entered on the sign is based on English text. Most fonts are Hangul, and Hangul fonts are made up of 11,000 character sets based on Unicode and 2,350 character sets based on the Korean Standard Hangul Code System (KSC), so the computing capacity of existing 3D video production programs increases exponentially, so production in Hangul is required. The 3D converted image has the limitation that it is difficult to implement because it takes a considerable amount of time and errors occur.

Therefore, 3D conversion of Korean fonts has issues with time, capacity, and safety, and it is burdensome to change the signboard model as it changes to various patterns. Therefore, it is easy and convenient to request signboard production online and demonstrate the results. Because it is difficult to make a choice, it is necessary to find a solution.

Republic of Korea Patent Publication No. 10-2018-0087636

Instead, a 3D font with a large capacity load is not used as input data, and the capacity load is A database is built in advance using small 2D fonts as input data, and then the outline data of the 3D font corresponding to the input 2D text is extracted and the 2D font is converted into a 3D font in real time, thereby creating a three-dimensional signboard. The purpose is to provide a sign production ordering system that is fast, accurate, and requires little memory by preventing excessive computer capacity occupancy, long time consumption, and frequent errors and bugs caused by the conversion process when displaying images.

According to one embodiment, the font storage unit analyzes the image of the 2D font, extracts 2D outline coordinates along the outline of the character, stores the outline coordinates as a digital image, and then stores the surrounding area based on the digital image. Converts image pixels into vectors, forms a group of multiple vector values generated at the same coordinates, defines and stores them as a path, and detects important vector values that indicate the maximum value, minimum value, and slope above a certain reference value among the vector values of the path. A vector detection unit that does; And, based on the important vector value, a number of parallel lines are drawn in the digital image of the two-dimensional font, and a relatively large mesh square formed based on the important vector value and line is first extracted, and then according to the slope of the internal vector. The relatively large mesh square is further subdivided to extract relatively small mesh squares, and the small mesh square is divided and converted into a combination of two mesh triangles to form contour data, and then loaded into the database in mesh triangle units. It further includes a split unit.

The sign production ordering system 10 according to a preferred embodiment of the present invention includes a sign production server 100, a database 200, and an ordering terminal 300.

The sign production server 100 receives a sign production order from a sign production client (orderer), calculates an estimate, and is equipped so that the orderer can access it through a network using an ordering terminal 300 such as a computer or mobile communication device. .

In order for an orderer to connect to the sign production server 100 and place an order for sign production, he or she must first select the content such as text, font, and size of the sign, as well as the appearance, type, and specifications of the sign, and then make a payment. Before making the final payment, In a situation where it is difficult to gauge what the sign will look like if it is produced in the form the orderer wants, or whether it will be properly recognized and produced in the type desired by the orderer, it is difficult to make an ordering decision.

In order to resolve these concerns of the orderer and support decision-making, the sign production system based on the online ordering method generally converts the content of the sign, such as the two-dimensional font entered by the orderer into the ordering terminal (300), into a three-dimensional version according to the type of sign selected by the orderer. By displaying the shape in the ordering terminal 300, the orderer can immediately check the actual shape of the sign he ordered online, allowing him to make an accurate and safe choice.

The sign production ordering system 10 of the present invention can accurately and quickly perform real-time conversion in representing the orderer's sign order into the three-dimensional shape, so it can support the orderer to make a quick and accurate selection, and also supports 3D conversion. The advantage is that a stable system can be maintained with low capacity and load requirements.

The database 200 is connected to the sign production server 100 and performs the function of storing digital images of two-dimensional fonts.

The sign production ordering system (10) of the present invention is characterized by quickly and accurately converting and simulating two-dimensional fonts, especially Hangul fonts, into three-dimensional Hangul fonts. To this end, the outline data of the two-dimensional Hangul font is extracted in advance and used for simulation. By storing and constructing the font in the database 200 and performing the task of finding the corresponding font and converting it into 3D in real time when ordering a signboard from the orderer, it is possible to secure the advantages of reducing load capacity and time reduction. The database 200 may be a place where contour data is extracted, stored, and constructed.

As described above, the ordering terminal 300 refers to all types of communication devices that the orderer can use to access the sign production server 100 through the network. After connecting to the sign production server 100, the ordering terminal ( 300), the type and standard of the sign to be installed are selected through the input means, and the font type, size, and text of the sign pattern to be expressed are input.

The ordering terminal 300 and the database 200 are each connected to the sign production server 100 through a network to perform their functions. Since commonly used devices can be used as known technologies, detailed descriptions will be omitted, and the present invention Since there are key features in the 3D Korean font conversion of the sign production server 100, these will be described in detail.

The sign production server 100 includes a font storage unit 110, a type setting unit 120, a pattern setting unit 130, a three-dimensional conversion unit 140, and a sign display unit 150 according to an embodiment of the present invention. It can be configured to include.

Among these, the font storage unit 110 is responsible for extracting and storing outline data of a two-dimensional Korean font in advance before ordering a signboard through the ordering terminal 300, and the type setting unit 120 or signboard display The unit 150 is in charge of a real-time conversion function that receives the input information when an order for sign production is placed at the ordering terminal 300 and converts the 2D font into 3D in real time to display a three-dimensional sign.

First, the font storage unit 110 functions to store an image file of a two-dimensional Hangul font in the database 200. It captures the two-dimensional Hangul font, extracts the outline coordinates of the font, and converts them into a digital image based on the coordinates. By converting, you can create an image file of a two-dimensional font.

To this end, the searcher may be configured to include a vector detection unit 111 and an image segmentation unit 112 according to an embodiment of the present invention.

First, the vector detection unit 111 begins by capturing an existing typeface (font).

The vector detection unit 111 captures an image of a two-dimensional font and then extracts two-dimensional outline coordinates along the outline of the character according to the character shape.

At this time, the outline coordinates are extracted once from the left to the right of the character, and then the same character is extracted once from the top to the bottom, and the outline coordinates are extracted a total of two times in each orthogonal direction. , the coordinates are stored as a digital image.

At this time, the logic for extracting coordinates extracts coordinates along the text, and when the pixel value changes, the coordinates are stored as a digital image.

In addition, the extraction of overlapping coordinates twice in the left, right, and top and bottom orthogonal directions is to ensure the accuracy of the calculated coordinates.

The digital image may be a bitmap file in one embodiment of the present invention, but any type of image file format or memory storage method used to store digital images may be used, so there is no limitation thereto.

When a 2D font is saved as a digital image, each coordinate of the image pixel around the outline is converted into a vector based on the digital image.

And multiple vector values generated at the same coordinates are stored as a group named Path.

At this time, each path establishes a parent and child relationship.

For example, in the case of '0', which is written as 'ㅎ' in the letter 'Hing' shown in (a) of Figure 5, there are an outline and an inner line that form the image of '0'. At '0', the path of the inner line is ) can be defined as the child path, and the outline path can be defined as the parent path.

Vector conversion is completed, all vector values according to the outline of the font are extracted, path setting is completed, and important vector values representing the maximum value, minimum value, and slope above a certain standard value are detected among the vector values of the path. I do it.

Important vector values are detected among all vector values, focusing on the maximum vector value, minimum vector value, and the part with a severe slope. This means that in order for the image segmentation unit 112, which will be described later, to segment the image of the font, the maximum and minimum vector values of the vector value are detected. This is because the minimum section, inflection section, etc. must be identified in order to attempt to segment the image based on those sections.

Image segmentation is an important preparatory task for 3D conversion through copying and overlapping fonts.

In order for each letter to have its own unique form to form a combination of letters and achieve meaning, consonants and vowels that appear similar but have different shapes can be combined and used as letters.

It is necessary to prepare for converting any type of font by converting the image of the character and font, which is a combination of each consonant and vowel, into a vector and recognizing it as a spatial coordinate concept, rather than storing it for each type of font. Image segmentation is like this. It is an important preparatory process, and in order to segment an image, you need to know the maximum, minimum, and inflection point (sudden slope) of the vector value to be able to properly segment at each necessary point without overlapping or overlapping.

In other words, the important vector value can be seen as playing a role in specifying the reference position for optimal image segmentation.

Through the above-described process, the vector detection unit 111 stores a digital image from a two-dimensional font, calculates a vector value, and finally performs the function of extracting important vector values.

The image segmentation unit 112 divides the image of the character to form outline data that is ultimately stored in the database 200.

To this end, the image division unit 112 displays a plurality of parallel lines in the digital image of the two-dimensional font based on the important vector values produced by the vector detection unit 111.

The multiple parallel lines relate to polygon processing, and known techniques in computer graphics can be applied.

After drawing a number of lines in the font of a two-dimensional digital image based on important vector values, a relatively large mesh square 113 is first extracted based on the important vector values, as shown in (a) of FIG. According to the slope of the internal vector of the large mesh square 113, it is further subdivided and a relatively small mesh square 114 is additionally extracted, as shown in (b) of FIG. 7.

Now, one small mesh square (114) is divided and converted to form a combination of two mesh triangles (115).

That is, as shown in FIG. 8, one mesh square can be composed of two mesh triangles 115. While one mesh square is composed of 4 vertices and 6 indices, each of the divided The mesh triangle 115 may be composed of three vertices and three indices.

In this way, for each character and font, when division is completed for each path by line drawing, extraction of large mesh squares (113), extraction of small mesh squares (114), and finally mesh triangles (115), the mesh The outline data of the corresponding font is defined using the vector values completed up to the triangle 115 and stored in the database 200.

At this time, the contour data can be loaded in mesh units.

Mesh is a well-known concept, and in order to calculate field values for each part of the structure for 3D simulation, each structure is divided into appropriate units and coordinate equations for each unit are calculated. Each of these equations The calculation area unit can be defined as a mesh, and in the present invention, the final divided mesh triangle (115) unit for each path can be a mesh, and the outline of each analyzed target character and font Once data generation is completed, it can be loaded into the database 200 in units of the mesh.

As described above, the roles of the vector detection unit 111 and the image segmentation unit 112 are performed, and thus the font storage unit 110 completes the task of storing outline data for all fonts for each Hangul character in advance.

Now, when the orderer accesses the sign production server 100 through the ordering terminal 300 and inputs the sign pattern, the sign production server 100 includes a type setting unit 120, a pattern setting unit 130, and a three-dimensional conversion unit ( 140) and the sign display unit 150 are driven to display a three-dimensional sign pattern. In particular, the three-dimensional conversion unit 140 uses the outline data for each font created and stored in the font storage unit 110 to display 2 The task of converting a dimensional font into a 3D font is performed.

First, the type setting unit 120 receives the type and specifications of the signboard from the ordering terminal 300, sets the type of signboard that the orderer wishes to produce, and stores it.

When the ordering terminal 300 connects to the sign production server 100 and registers as a member through the homepage, the type setting unit 120 may be presented on the screen in the first order when guided sequentially as a follow-up procedure.

The pattern setting unit 130 receives the font, size, text, etc. of the sign pattern from the ordering terminal 300 as the contents of the sign displayed on the exterior of the sign, and stores this in the database 200, prior to the type setting unit ( It is managed as order information for the relevant orderer along with the type of sign stored in 120).

Once the content the orderer wishes to produce is confirmed through the type setting unit 120 and the pattern setting unit 130, the three-dimensional conversion unit 140 and the sign display unit 150 select 3 signs that match the orderer's intention. A 3D image is created and displayed on the screen.

Among them, the three-dimensional conversion unit 140 performs the core function of converting the two-dimensional font input from the ordering terminal 300 into a three-dimensional font.

For this purpose, the three-dimensional conversion unit 140 may be configured to include a three-dimensional copy unit 141 and a three-dimensional conversion unit 142.

The three-dimensional copy unit 141 receives the sign pattern input from the ordering terminal 300 in the pattern setting unit 130, recognizes the font of the sign pattern input by the orderer, and then stores the font corresponding to the font in the database ( 200) to retrieve the outline data of the corresponding font.

The three-dimensional copy unit 141 extracts the outline data of the signboard pattern font, uses it as one side, and copies the one side to create the other side of the font. Here, one side can be the front (or back), and the other side can be the back (or front), forming a plane for the front and back of the character, respectively.

Previously, according to the preliminary work of the font storage unit 110, the outline data for each font of the two-dimensional Hangul character is divided into a small mesh square 114 of the minimum unit for each vector coordinate in the path unit and a mesh triangle ( 115), so if you use this as one side and copy it to create the other side, the pair of fonts placed on the front and back will have the same outline data, and both the front and back will have coordinates in units of small mesh triangles (115). It will be held.

When the copying operation by the three-dimensional copy unit 141 is completed, the 3D conversion unit 142 converts the x-axis and the The task of interconnecting mesh triangles 115 with the same y-axis value is performed.

As a result, a z-axis value is created between one side and the other side with the same contour data, and the coordinates of the side that forms the thickness between one side and the other side are created, completing a three-dimensional shape.

In this way, the three-dimensional copy unit 141 retrieves the outline data for each font previously stored in the database 200 by the font storage unit 110 according to the text and font input and selected in the ordering terminal 300 and designates it as one page. , when this one side is copied to create the other side, the 3D conversion unit 142 connects the coordinates of the mesh triangle 115 at the same point of the one side and the other side, and the space forming the thickness between the front and back sides is connected to the one side and the other side. By connecting the mesh triangles 115 according to the coordinates, the three-dimensional shape is finally completed.

The above-described three-dimensional conversion process is a key feature of the present invention and can shorten time as well as minimize storage and computing capacity, thereby dramatically reducing the overload caused by conventional processing.

Through the font storage unit 110 and the three-dimensional conversion unit 140 of the present invention described above, the Korean two-dimensional font can be converted into a three-dimensional font, and the converted three-dimensional font can be used as an embodiment of the present invention. It can be defined as AFont.

The reason for applying AFont as in the present invention is briefly explained as follows.

In general, all game typefaces, or fonts, are texture-based, and this is a natural idea due to the nature of the game engine.

If you create a three-dimensional (3D) font based on representative assets commonly used in the market as assets to complement this, you will face significant limitations. First, there are 11,000 Hangul characters based on Unicode and the Korean Standard Hangul Code System (KSC). It consists of 2,350 character sets, so when using representative assets on the market, the capacity increases exponentially. Therefore, bugs that cause malfunctions are frequent, and since it is a Korean font, optimization for application to overseas developed assets is very poor.

The basic text processing methods in Unity Asset, which is used as a representative tool for three-dimensional functions, are all produced in English-speaking countries, so there are fatal errors in Korean processing, and malfunctions occur when changing or modifying Korean Unicode in real time. Frequent.

For the above reasons, there are significant risk factors in demonstrating in 3D the effects that can be displayed in the actual production of a sign, such as implementing the halo effect, and there are problems that make fixing bugs very difficult.

For this reason, AFont of the present invention was developed, through which a unique typeface (font) conversion format can be established and a two-dimensional font can be implemented and produced as a three-dimensional font.

The reason for creating a method such as AFont and performing three-dimensional work is that not only is the functionality improved by three-dimensionalization, but it also allows for immediate correction when errors occur, thereby speeding up the overall work speed.

As described above, AFont extracts the outline data of the two-dimensional Korean font in advance and stores it in the database 200, and when converting in real time according to an order, the outline data stored in the database 200 is called and used. It has the advantage of being able to carry out three-dimensional work fairly quickly, accurately, and without errors.

When the three-dimensional conversion unit 140 is performed according to the above-described procedure and the real-time conversion of the two-dimensional pattern into a three-dimensional pattern is completed, the sign display unit 150 simulates and displays the draft sign as a final procedure.

The sign display unit 150 combines the sign pattern converted into three dimensions in the three-dimensional conversion unit 140 with the sign type stored in the type setting unit 120 and displays the final three-dimensional sign shape on the screen of the ordering terminal 300. It can be simulated.

The orderer makes a decision by looking at the final sign shape displayed on the ordering terminal 300 in three dimensions from various angles, and when changing the pattern or sign shape, etc., the above-described type setting unit 120, pattern setting unit ( 130), after performing real-time conversion work in the three-dimensional conversion unit 140, the three-dimensional shape of the new sign is simulated again through the sign display unit 150.

Through the above procedure, the sign production orderer can connect to the sign production server 100 through the ordering terminal 300 and check, modify and order the finished shape of the sign with the desired shape and pattern in 3D in real time, and use the sign production ordering system. (10) is a database 200 of pre-produced outline data for each font in the font storage unit 110 and a real-time 3D font conversion operation of the 3D conversion unit 140 based on this, enabling fast and error-free low-capacity processing. It is possible to provide highly reliable simulation demonstrations.

Based on the above-described structure, an example of use of the sign production ordering system 10 of the present invention will be described as follows.

First, before receiving an order from the orderer, the sign production server 100 performs preliminary work by extracting outline data for each character and font of Hangul and storing it in the database 200.

To this end, the sign production server 100 drives the font storage unit 110, and the vector detection unit 111 of the font storage unit 110 generates images of characters for each Korean font in a two-dimensional image as shown in FIG. 3. is captured, and the two-dimensional outline coordinates are extracted along the outline of the corresponding character as shown in Figure 4 and converted into a digital image.

Then, image pixels are extracted based on the digital image for each outline coordinate, converted to a vector, and a plurality of vector values for each coordinate are formed into groups and defined as a path, and then the same as shown in (b) of FIG. Among the vector values of the path, the vector values at multiple points representing the maximum, minimum, and sharp slopes are selected as important vector values.

As a result, when the vector detection unit 111 completes the function of selecting important vector values, the image segmentation unit 112 divides the image of the font based on the important vector values, extracts the outline data, and divides it into a mesh unit database ( 200) and proceed with the saving operation.

The image segmentation unit 112 displays a plurality of parallel lines based on important vector values selected for the two-dimensional font, as shown in FIG. 6.

Then, as shown in (a) of FIG. 7, a relatively large mesh square 113 formed surrounded by lines and important vector values is first extracted, and then the large mesh square 113 is subdivided as shown in (b) of FIG. 7 to determine the relative size. It is extracted as a small mesh square (114).

And when the small mesh square 114 is divided into two mesh triangles 115 as shown in FIG. 8, the coordinates of the more precisely divided mesh units can be obtained, and the detailed coordinates and index information of the mesh triangle 115 can be obtained. By extracting, it is finally possible to calculate the outline data of the corresponding character font.

In this way, the font storage unit 110 calculates outline data for each character and font of Hangul through the continuous operation of the vector detection unit 111 and the image segmentation unit 112 and then stores it in the database 200.

Now, as shown in FIG. 1, the orderer accesses the sign production server 100 through the ordering terminal 300 and requests the production of a sign.

In the ordering terminal 300, as shown in FIG. 11, the type setting unit 120 presents the types of signboards and a process of selecting the desired signboard type is performed. Afterwards, the pattern setting unit 130 selects the type of signboard as shown in FIG. 12. As shown, the text, font, size, etc. of the sign are input and the sign pattern is set.

Once the input of sign production details from the ordering terminal 300 is completed, the sign production server 100 drives the three-dimensional conversion unit 140 and the three-dimensional conversion unit 142 to convert the characters of the input sign content into three dimensions. Proceed with converting it into shape.

First, the three-dimensional conversion unit 140 extracts pre-stored outline data corresponding to signboard letters and fonts from the database 200 and uses the outline data of the letters as one side, as shown in (a) of FIG. 9, and (b) in FIG. 9. ), the above-mentioned one side is copied to create a copy of the other side having the same contour data.

Then, the 3D conversion unit 142 matches the contour data of the same coordinates opposing the one side and the other side of the character as a pair, then connects the mesh triangles 115 on the same coordinates to each other to form a side surface between one side and the other side of the character. We proceed with the work of filling the space.

In this case, one side and the other side become two-dimensional shapes with plane coordinates of the x-axis and y-axis, respectively, but the z-axis is created by connecting one side and the other side, completing a three-dimensional shape that combines the one side and the other side.

The characters of the sign inputted at the ordering terminal 300 are finally completed into a three-dimensional shape through the above-described procedure, and this is done by extracting and storing the outline data of all the fonts for each Korean character in the font storage unit 110. , the outline data of the corresponding font is called for the characters input from the ordering terminal 300, and real-time conversion into a 3D shape is performed, so it is fast, has few errors, and has the effect of significantly reducing processing capacity. .

Once the 3D conversion of the signboard pattern is completed above, the signboard display unit 150 grafts the converted signboard pattern onto the type of signboard selected in the type setting unit 120 and then displays the ordering terminal 300 as a 3D image. It is simulated, and the orderer can view the displayed video and choose whether or not to order. If another type of sign and pattern is selected, the same procedure is repeated and the form of the sign desired by the orderer is repeatedly presented.

The embodiments of the present invention described above are merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible.

Therefore, it will be understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached patent claims.
