3 to 7 are diagrams for explaining a first embodiment of a method of drawing an image file. Hereinafter, the description of the above-described parts may be omitted.

3 is a flowchart illustrating a file conversion method according to the first embodiment of the present invention, and converts image files such as JPG files, GIF files, PNG files, or document files such as PDF files to usable files such as CAD files. It shows how to draw.

Referring to FIG. 3 , the file conversion method according to the first embodiment of the present invention includes (a) receiving a drawing target file (S101); (b) extracting the outline from the input file (S102 ~ S104); (c) detecting and coordinated corner feature points based on the extracted outline (S105); (d) connecting the detected corner feature points with a line (S106); (e) removing noise from the lines connected in step (d) (S107); (f) detecting an image from which the outline has been removed from the input file (S108); (g) template matching the image from which the noise has been removed in step (e) and the image detected in step (f) (S109); (h) generating a 2D drawing for the input file by applying the pre-stored outer coordinate information and element coordinate information to a CAD program after matching the template in step (g) (S110); (i) calculating a 3D drawing based on the 2D drawing generated in step (h) (S111).

Meanwhile, the step (b) includes (b1) converting the input image file information to a gray scale (S102); (b2) performing truncation coding by bit-plane slicing the grayscale-converted information, storing the most significant bit information image among the truncation-encoded information, and converting the truncation-encoded information to a median It may include steps (S103 to S104) of extracting an outline by smoothing using a filter (Median Filter) and storing the resultant image.

In step (f), information on valid linear components in the noise-removed image is stored, the element is detected when the outline detection is completed, and the image obtained by smoothing the converted grayscale image and the median filter to extract the outline. It is possible to detect an image from which the outline has been removed by calculation.

In addition, the step (h) stores the position value of the element matched in the template matching, calculates the position value of the image on which the outer detection is completed and the stored element to extract element coordinate information, and the outer coordinate information and the element coordinate information can be applied to CAD programs to make 2D drawings of input files (image files, PDF files).

Hereinafter, the file conversion method according to the first embodiment of the present invention will be described in more detail.

First, a drawing target file to be drawn is received through the input unit 10 (S101). Here, the file to be drawn includes at least one of an image file (JPG file, GIF file, PNG file, etc.) and PDF file. 4 is an exemplary diagram in the case where the received file is an image file.

When an image file is input, the image file processing unit 20 processes and draws the input image file. For example, the input image file information is converted into gray scale (image 1) (S102). A digital image refers to an image in which the value of each pixel is one sample, and only information of luminance can be transmitted. This kind of image, also known as black and white, consists of gray shadows, ranging from the softest "black" to the strongest "white". Therefore, by converting the image file information into grayscale, the brightness of each pixel can be determined.

Next, truncation coding is performed on the grayscale-converted image information using a bit-plane slicing method. That is, lossy compression.

For example, one pixel of an 8-bit gray image consists of 8 bits, and among the 8 bits, the most significant bit is called MSB and the least significant bit is called LSB. Lossy compression is performed by truncating the lower 4 bits.

Thereafter, the most significant bit information image (image 2) among the truncation-encoded information is stored in the storage unit 30, the truncation-encoded image information is smoothed using a median filter to extract an outline, and the result Save the image (image 3).

Here, smoothing using the median filter means replacing the average value of the intensity of each pixel with the median value of the intensity within points surrounding the pixel. This smoothing method is particularly effective when the noise form is strong and consists of elements such as elongated lines, and edge sharpening is well preserved.

4 shows an example of an image file to be converted into a drawing file by the file conversion method according to the first embodiment, and FIG. 5 shows an example of a result of extracting an outline from the image file shown in FIG. .

Next, corner feature points are detected and coordinated based on the extracted outline in step S105.

6 shows an example of a result of extracting corner feature points from the image file.

For example, the corner image (image 4) is detected through Harris corner detection on the image information from which the outline is extracted, and the corner feature point is calculated by calculating the outline detection image (image 3) and the corner image (image 4). can be detected.

Here, when Harris Corner Detection creates and searches an arbitrary area (Window) in the image, a point where there is no change in all directions or changes in all directions rather than only in a certain direction along the edge is the corner. It is an algorithm that recognizes points (edges).

Next, the corner feature points detected in step S106 are connected with a line (image 5). Thereafter, noise is removed from the connected lines in step S107.

For example, noise on the continuous lines may be removed by calculating (logical product) an image (image 5) in which the outline is connected to the detection image (image 3) and corner feature points are connected with a line.

Next, in step S108, an image from which the outline is removed from the image file is detected.

For example, information on a valid linear component in an image from which noise is removed may be stored, and an element may be detected in an image (image 6) in which outlier detection is completed.

Here, the element may mean an image other than an outline in the image file as shown in FIG. 4 . For example, a door, a window, a sink, etc. may be said to be the said element.

Then, the image from which the outline has been removed may be detected by calculating the converted grayscale image (image 1) and the image (image 3) obtained by smoothing and extracting the outline using the median filter.

Thereafter, in step S109, the image from which the noise has been removed and the image from which the element is detected are subjected to template matching.

7 illustrates an example of a state in which a noise-removed image and an image in which elements are detected are matched with a template.

For example, an image in which noise is removed and an image in which elements are detected may be superimposed.

Here, the template matching may be performed by prioritizing a door, a window, a washbasin, and the like.

Next, after matching the template in step S110, the pre-stored outer coordinate information and element coordinate information may be applied to the CAD program to generate a 2D drawing for the input file.

For example, the element coordinate information is extracted by storing the position value of the element matched in the template matching (image 7), calculating the image where the outline detection is completed (image 6) and the stored element position value (image 7) In addition, by applying the outer coordinate information and element coordinate information to the CAD program, the image file can be 2D drawn.

Thereafter, in step S111, a 3D drawing is calculated based on the generated 2D drawing. Here, a method of calculating a 2D drawing into a 3D drawing may be performed using Rhino, 3D MAX, AutoCad, Archicad program, or the like.

According to one embodiment of the present invention as described above, image files such as JPG files, GIF files, PNG files, etc. or document files such as PDF files can be drawn, so that the image files can be reused, and the image files Convenience of use can be promoted by drawing by automatic program without user's manual work.

On the other hand, in addition to the general 2D image file, an image of a user's hand-drawn drawing, for example, an image file (JPG file, GIF file, PNG file, etc.) It may also be possible to process and convert it into a 3D drawing. Hereinafter, referring to the accompanying drawings, it will be described.

8 to 11 are diagrams for explaining a second embodiment of a method of drawing an image file. Hereinafter, the description of the above-described parts may be omitted.

8 is a flowchart illustrating a drawing method of an image according to a second embodiment of the present invention. (a) converting drawn drawing information into a Lab channel (S201 to S202); (b) separating the Lab channel converted in step (a) into respective channels, and processing the contrast of the separated L channel to remove the influence on lighting (S203); (c) extracting an outline from the image from which the effect of lighting is removed in step (b) and storing the resultant image (S204); (d) detecting the blob by labeling the image stored in the step (c) (S205); (e) detecting and storing a boundary line based on the detected blob (S206); (f) determining a direction by sampling a set of innumerable points forming the detected boundary line and detecting an outline (S207); (g) detecting the image from which the outline has been removed by calculating the image from which the influence of lighting has been removed in step (b) and the image obtained by smoothing the image using a median filter to extract the outline (S208); (h) template matching between the image from which the outline is removed in step (g) and the image in which the element is detected (S209); (i) generating a 2D drawing for the input image by applying the pre-stored outer coordinate information and element coordinate information to a CAD program after matching the template in step (h) (S210); (j) may include a step (S211) of calculating a 3D drawing based on the 2D drawing generated in step (i).

The drawing conversion method according to the second embodiment will be described with reference to FIGS. 1 and 2 above.

First, an image to be drawn is received through the input unit 10 (S201). The image to be drawn here is a drawing drawn by the user (a sketched drawing). For example, a user draws a drawing by hand to produce a design drawing. Then, image information is generated by photographing the drawn drawing using a photographing means such as a camera. That is, image information such as a JPG file, a GIF file, and a PNG file is generated by taking a drawn drawing.

When the image information is input, the image file processing unit 20 processes the input image information to make a drawing. For example, drawing information (image information) drawn in the lighting effect removal module 31 is converted into a Lab channel (image 1) (S202). That is, the drawn drawing information is converted into an L channel having light and dark information, and a channel and b channel having color information.

Next, the effect of lighting is removed for the converted Lab channel. That is, only the image information of the actually drawn drawing is extracted by removing the effect of lighting generated when photographing the drawn image information.

To this end, as shown in FIG. 9, the converted Lab channel is separated into each channel (L channel, a channel, b channel) (S301), and the separated L channel is filtered with a median filter to remove noise ( S302). Here, the higher the order of the median filter, the better, but in the present invention, it is set to 51. This is because the higher the order, the lower the performance, so the optimal order value to obtain performance was set to 51. If the L-channel image is filtered with a median filter, the surrounding noise information is blurred, leaving only the flow of light. Therefore, in order to remove the lighting effect of the image, the light flow is extracted from the image by filtering the L channel with a median filter. Thereafter, the L channel from which the noise has been removed is inversely transformed (Not) (L_channel_not) (S303), and the inversely transformed image (L-channel_not) and the L channel image are merged (Merge) to remove the effect of illumination (S304).

Next, in step S304, the most significant bit information is received through bit slicing from the image from which the influence of lighting is removed, the image (image 2) in which only the outline information is expressed is extracted and stored in the storage unit 30 .

Thereafter, a blob is detected by labeling the stored image (S205).

Here, since labeling is an image processing technique that is basically applied in image processing, a detailed description thereof will be omitted. Next, a boundary line (vector) is detected and stored based on the detected blob (image 3) (S206). Here, the boundary line is the process of detecting the largest image from the detected blob.

Thereafter, by sampling a set of innumerable points forming the detected boundary line, the direction is determined and the outline is detected (image 4) (S207).

For example, as shown in FIGS. 10 and 11, cross-product calculation is performed on a Y-axis normal vector and a vector for two points on the x and z axes in a 3D environment based on the detected boundary line image (B = TxN) (S301). Then, the cross product operation result for each point is normalized to a vector having a magnitude value of 1, and magnitude values of each vector are compared (S302). In addition, the correlation of each point is analyzed based on the result of comparing the magnitude values of each vector (S303), and the direction of each set of points is determined based on the analyzed correlation (S304) to extract the outline. .

Here, the outline extraction refers to an operation of sampling points by finding a correlation with each other while finding N in the drawing as shown in FIG. 11 . Correlation refers to a relationship whether in the same direction or in a different direction. If the set of several points is defined as a straight line, the direction of N has almost the same direction.

Thereafter, the sampled points are stored as outlines.

When the outline detection is completed through this process, the process moves to step S208 to detect and store the image from which the outline has been removed (image 5). For example, information on a valid linear component in an image from which noise is removed is stored as an outline, and when the outline detection is completed, the element is detected. The element detection is to detect an image from which the outline has been removed by calculating an image from which the influence of the illumination has been removed and an image obtained by smoothing the image using a median filter and extracting the outline.

Next, the image in which the outline is removed and the image in which the detected element is detected are matched with a template (S109). For example, the image from which the outline is removed and the image in which the element is detected are superimposed. Here, in the template matching, it is preferable to template matching the door/window/wash basin with priority.

Thereafter, after template matching in step S210, the pre-stored outer coordinate information and element coordinate information are applied to the CAD program to generate a 2D drawing for the input file. For example, the position value of the element matched in the template matching is stored, the element coordinate information is extracted by calculating the position value of the image on which the outline detection is completed and the stored element, and the outline coordinate information and the element coordinate information are applied to the CAD program. 2D drawing of the image file.

Thereafter, in step S211, a 3D drawing is calculated based on the generated 2D drawing. Here, as a method of calculating a 2D drawing into a 3D drawing, a general Rhino, 3D MAX, AutoCad, or Archicad program may be used.

According to the present invention described above, it is possible to easily draw a hand-drawn drawing as a design drawing, and there is an advantage in that the user can conveniently and freely calculate various design drawings. In particular, by drawing image information by an automatic program without the user's manual work, it is very convenient.

It is possible to use the 3D drawing converted according to the method described above as interior information. Hereinafter, referring to the accompanying drawings, it will be described.

12 to 14 are diagrams for explaining the configuration and schematic functions of the interior information processing apparatus according to the present invention. Hereinafter, the description of the above-described parts may be omitted.

Thereafter, it may be determined whether the user terminal 100 selects an interior object (S610).

As a result of the determination, when an interior object is selected, a 3D drawing of the selected interior object may be displayed on the screen of the user terminal 100 ( S620 ). An example of a 3D drawing of an interior object is disclosed in FIG. 17 .

Referring to FIG. 21 , the interior server 200 transmits a 3D drawing including the selected object (eg, TV 300 ) to the company server 300 as shown in FIG. 18 , and requests an estimate based on this (S667). can That is, the interior server 200 sends the 3D drawing itself including the object selected by the user to the company, and requests a quote corresponding to the 3D drawing sent.

Thereafter, the interior server 200 may receive a quotation from the company server 300 ( S662 ).

Thereafter, the interior server 200 may recommend/provide the quotation received from the company server 300 as recommendation information to the user terminal 100 ( S663 ).

Alternatively, the company server 300 may transmit a quote corresponding to the information received from the interior server 200 to at least one of the interior server 200 or the user terminal 100 . That is, in the company server 300 , it is possible to directly transmit the quotation to the user terminal 100 without going through the interior server 200 .

Alternatively, as in the case of FIG. 22 , the interior server 200 does not transmit the 3D drawing to the company server 300 , but transmits only the information about the selected item, for example, the selected object, to the company server 300 , and based on this, It is possible to request an estimate (S664).

In this case, the company may prepare a quote only with information on the added object and transmit it to the interior server 200 .

Even in this case, the company server 300 may transmit a quote corresponding to the information received from the interior server 200 to at least one of the interior server 200 or the user terminal 100 .

Meanwhile, the interior server 200 transmits information to a plurality of company servers 300 , and it is also possible to receive an estimate from the plurality of company servers 300 .

In this case, it is possible for the interior server 200 to transmit all quotations to the user terminal 100 . Alternatively, the interior server 200 may classify a plurality of received quotations and provide only a predetermined number of quotations to the user terminal 100 .

For example, as in the case of FIG. 23 , after receiving the quotation from the company server 300 ( S662 ), the interior server 200 may analyze the received quotation ( S665 ).

Thereafter, it is possible to check the cost in each estimate (S666).

In addition, it is possible to classify the estimate according to the cost (S667).

For example, as in the case of FIG. 24 , the cost of each company may be analyzed by analyzing the respective quotations received from the electronic stores A, B, C, and D. In addition, each estimate can be classified into recommended and non-recommended. In detail, the interior server 200 may recommend at least one company according to the order of the lowest price (cost) in the quotation received in response to the selected object. For example, it is possible to recommend the one company (electronic store) with the lowest price for a 60-inch TV. Alternatively, it may be possible to select and recommend a company with the lowest cost in consideration of the shipping cost and installation cost of the TV together with the TV price.

Meanwhile, in the interior server 200, it is possible to provide recommendation information in consideration of the evaluation score (grade) given to each company. Hereinafter, referring to the accompanying drawings, it will be described.

Referring to FIG. 25 , in the recommendation step, a company may be first selected according to a rating ( S668 ). For example, as in the case of FIG. 18 above, the interior server 200 selects a predetermined number of companies in the order of the highest ratings for the 60-inch TV 300 in response to the selected 60-inch TV 300. can

Thereafter, the interior server 200 may transmit a 3D file including the selected object to the company server 300 of the selected company or transmit information on the selected object, and request a quote (S661, S664).

Thereafter, the interior server 200 may receive the quotation from the company server 300 ( S662 ), and provide the received quotation as recommendation information to the user terminal 100 ( S663 ).

For example, as in the case of FIG. 26 , the recommendation information provided to the user terminal 100 may include rating information allocated to each of the companies (A, B, C, and D electronic stores). In addition, it is possible to set a company whose rating is higher than a preset reference rating as a recommended company.

Alternatively, in the interior server 200, it is possible to select a recommended company in consideration of the price (cost) on the quotation and the rating of the company.

For example, as in the case of FIG. 27 , it is assumed that the interior server 200 receives quotations from the electronic stores A, B, C, and D for the 60-inch TV 300, respectively.

The price (cost) on the estimate for e-store A is 1 million won and the rating is 95 points, the price on the estimate for e-store B is 1.2 million won and the rating is 98 points, the price on the estimate for e-store C is 2.5 million won and the rating is 92 points. , D The price on the estimate of the electronic store is 1 million won, and the rating may be 65 points.

Here, assuming that the reference cost is 1.5 million won or less, and the reference rating is 90 points or more, the interior server 200 selects A, B electronic stores among A, B, C, and D electronic stores as recommended companies, It is possible to provide the quotation received from the company server 300 of the electronic store B as recommended information to the user terminal 100 .

Here, although a company (electronic store) that sells the object for an object, for example, an electronic product (TV 300) is selected and recommended as a recommendation company, the present invention may not be limited thereto. For example, in this document, it may be possible to set a company corresponding to an object (electronic product) as a manufacturer of the object rather than a sales store.

As such, those skilled in the art to which the present invention pertains will understand that the above-described technical configuration of the present invention may be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention.

Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the following claims rather than the foregoing detailed description, and the meaning and scope of the claims And all changes or modifications derived from the equivalent concept should be construed as being included in the scope of the present invention.
