In addition to a " document "made of paper (paper), the barcode position notification system also includes a bar code, a QR code, and a barcode printed on various types of objects such as vinyl, plastic, clothing Can be scanned. Here, when using a watermark, the bar code position notification system can notify the position of the bar code without outputting a separate pattern in the paper.

In addition, the barcode position notification system can be used for at least one of a smart device such as a smart phone or a tablet phone equipped with a barcode reader or a camera module for scanning a barcode or pattern in a document, and an OCR device for reading a large amount of computer and document Hereinafter, for convenience of explanation, it is assumed that the barcode position notification system of the present invention is implemented by a smart device.

FIG. 1 is a block diagram illustrating an internal configuration of a bar code position notification system according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, the barcode position notification system 100 may include a scan unit 110, an acquisition unit 120, and a processing unit 130. The barcode position notification system 100 may further include a determination unit 140, an output unit 150, a transceiver unit 160, and a memory unit 170 according to an embodiment of the present invention.

The scan unit 110 scans an arbitrary area in the document including at least the first pattern to form a scan image.

For example, the document is divided into a plurality of areas of uniform size (e.g., a square having one side of 4 cm in length), and the remaining area excluding the barcode-containing area (barcode area) Patterns may be included, respectively. At this time, the position information of the barcode may be a value obtained by counting the number of regions from an arbitrary region to a barcode region in the horizontal direction and the vertical direction, respectively.

The scan unit 110 may form a scan image by scanning an arbitrary area of a document through a barcode reader or a camera module provided in the barcode position notification system 100. The scan image may include a direction from the arbitrary area to a barcode area and a first pattern indicating the number of areas.

For example, referring to FIG. 3, the scan unit 110 may scan an arbitrary area (upper left corner 304) in a document to form a scanned image including the first pattern 303. In addition, the scan unit 110 may form a scan image including the first pattern 306 by scanning an arbitrary area (center 305) in the document. At this time, when the scanning unit 110 scans an arbitrary area (right lower edge 302) in the document, it can form a scanned image including the barcode 301.

In another example, the document is divided into a left upper corner area, a right upper corner area, a lower left corner area, and a lower right corner area (see FIG. 5), and barcodes are included in any one of the four corner areas, A plurality of patterns may be included. The scan unit 110 may form a scan image in which an arbitrary corner area in the document is scanned for a barcode scan. The scan image may include a position pattern indicating a corner where a barcode is positioned in a document, and a direction pattern indicating a direction (forward direction, reverse direction, etc.) of the document.

The acquiring unit 120 acquires, from the first pattern, position information of the barcode in the document when the barcode is not included in the scanned image.

For example, referring to (i) of FIG. 3, the acquiring unit 120 does not include the barcode 301 in the scan image formed by scanning the arbitrary area 304 in the document, The position information '4,6' of the bar code 301 can be obtained by analyzing the first pattern 303 and the position information '4,6' of the bar code 301 can be obtained from the arbitrary area 304, The number of areas in the horizontal (left / right) direction from the bar code area 302 to the bar code area 302 is '4', and the number of areas in the vertical (up / down) direction is '6'.

Since the bar code 301 is not included in the scan image formed by scanning the arbitrary area 306 in the document, the acquiring unit 120 analyzes the first pattern 305 included in the scan image, (2, 3) 'of the bar code 301 can be obtained from the arbitrary area 306 to the bar code area 302. The position information' The number of areas in the right direction is '4', and the number of areas in the vertical (up / down) direction is '6'.

The processor 130 determines movement information about the scan area in the document to be scanned by the scan unit 110 based on the obtained position information and notifies the scan information.

For example, the processing unit 130 identifies the direction of the barcode area from the first pattern, multiplies the number of horizontal or vertical lines in the area of the position information of the barcode with the size of each area in the document , Calculate the distance to the barcode area, and determine the movement information, including the identified direction and the calculated distance. The processing unit 130 may notify that the scan area is moved by the calculated distance in the identified direction according to the determined movement information.

For example, referring to (i) of FIG. 3, the processing unit 130 determines whether the first pattern 303 in the scanned image formed by scanning the arbitrary area 304 in the document is scanned, The direction in which the bar code area 302 is positioned from the arbitrary area 304 is identified as the 'right down direction' and the position information '4,6' of the bar code 301 obtained from the first pattern 303 The number of regions 4 in the horizontal (right) direction and the number of regions 6 in the vertical (down) direction are multiplied by the length of one side of each region (e.g., 4 cm) Quot; 4 * 4cm " in the horizontal direction to the barcode area 302 and a distance " 6 * 4cm " in the vertical direction as the movement information.

The processing unit 130 moves the scan area in the document to be scanned next by the scan unit 110 to the area 302 separated by 16 cm to the right and 24 cm to the bottom in the current arbitrary area 304 according to the movement information You can be notified by voice or vibration.

For reference, the memory unit 170 records a pattern library related to a pattern including positional information of the barcode in the document. For example, referring to FIG. 3 (ii), the pattern (e.g., an arrow) included in an arbitrary area of the document is always pointed to the barcode area, The right direction, the right direction, the right direction, the upper left direction, and the like can be identified as the direction in which the bar code area is located. That is, the processing unit 130 guides the direction in which the barcode is positioned to the user on the basis of the pattern scanned shape, so that it can guide the direction in which the barcode is positioned without the top / bottom or left / right distinction of the document.

3 (3), the processing section 130 reads out the movement information of the bar code obtained from the first pattern and the movement information of the bar code obtained from the first pattern (Eg, '4 * 4 cm' to the right and '6 * 4 cm' to the bottom) corresponding to the position information (eg, (4, 6) .

As described above, according to the embodiment of the present invention, the position of the barcode in the document can be easily recognized by the blind using the sound, so that the blind can scan the barcode in the document accurately and quickly and easily can do. That is, the barcode position notification system 100 obtains the position information of the barcode in the document from the first pattern in the scan image formed by scanning an arbitrary area in the document, and outputs the movement information determined based on the obtained position information as a sound The visually impaired person can easily move the scan area in the document according to the movement information and scan the barcode in the document accurately.

According to an embodiment, the barcode position notification system 100 may further include a determination unit 140. [

The determination unit 140 determines whether the barcode is included in the scan image formed by scanning the scan area. When the barcode is included in the scanned image, the processing unit 130 can notify the completion of the barcode scan by voice or vibration.

For example, referring to (i) of FIG. 3, the processing unit 130 may include an area 302 shifted '16 cm' to the right and '24 cm' downward from the arbitrary area 304 in the document, Is scanned as a scan area and the barcode 301 is included in the scan image formed, the completion of the barcode scan can be notified as voice or vibration.

As described above, according to an embodiment of the present invention, when a barcode is included in a scan image formed by scanning the scan area, the barcode scan completion is notified through a sound, .

Alternatively, if the barcode is not included in the scanned image, or if only a part of the barcode is included in the scanned image, the processing unit 130 may notify the barcode scan failure by voice or vibration.

If the barcode is not included in the scanned image or only a part of the barcode is included in the scanned image, the processing unit 130 can re-determine the movement information based on the position information.

For example, referring to (i) of FIG. 3, the processing unit 130 may scan the area 307 moved according to the movement information 'move 16 cm to the right and 24 cm to the bottom in the current arbitrary area 304' (4, 6) 'of the barcode used for determining the movement information, if the barcode is not completely contained in the scan image formed by scanning as the' area ', the movement information' 4cm movement downward 'can be re-determined.

In addition, the determination unit 140 may determine whether a second pattern different from the first pattern is included in the scan image formed by scanning the scan area. If the second pattern is included, the acquiring unit 120 reacquires the position information of the barcode in the document from the second pattern, and the processing unit (130) So that movement information on the scan area can be determined.

For example, referring to (i) of FIG. 3, the judging unit 140 judges whether or not the region 305 moved according to the movement information 'movement 16 cm to the right in the current arbitrary region 304 and 24 cm downward' The acquiring unit 120 determines whether the second pattern 306 is included in the scanned image formed as a scan area and includes the second pattern 306. If the second pattern 306 is included, (2, 3) 'of the bar code 301 from the position information' 2, 3 '.

The processing unit 130 identifies the direction in which the bar code area 302 is located from the area 305 as a 'right down direction' through the shape (shape) of the second pattern 306, (For example, '4cm') of the area on each side of the area ('2', 3 ') in the horizontal direction (right direction) 2 * 4 cm 'in the horizontal direction from the area 305 to the bar code area 302 and the distance' 3 * 4 cm 'in the vertical direction can be calculated as the movement information. The processing unit 130 instructs the scanning unit 110 to scan or scan the document in the area to be scanned next by 8 cm to the right in the area 305 and to the area 302 separated by 12 cm in the downward direction according to the movement information, .

That is, according to an embodiment of the present invention, when a blind person accidentally moves to another area other than the scan area according to the notification, the position of the barcode is confirmed again in the current area to notify the scan area in the document to be scanned next Thereby enabling the visually impaired to accurately scan the bar code.

In addition, the determination unit 140 may determine whether a cut surface of the document or a first pattern having an abnormal shape is included in the scan image formed by scanning the arbitrary area of the document. The processing unit 130 may notify that the document is in a folded state when a cut surface of the document or a first pattern of an abnormal shape is included.

For example, referring to FIG. 4 (i), the determination unit 140 determines that the cut image of the document 410 is included in the scan image formed by scanning the arbitrary area 411 in the document 410, The processing unit 130 may notify the user that the document 410 is in a folded state (out of the document area) by voice or vibration so that the visually impaired person can recognize the current state of the document 410 only by the sound.

4, the determination unit 140 determines that the first pattern is included in the scan image formed by scanning the arbitrary area 412 in the document 410, and the processing unit (not shown) 130 may notify the blind person that the document 410 is in a folded state (abnormal shape) by voice or vibration.

In addition, the determination unit 140 may determine whether the number of times that the first pattern is not included in the scan image formed by scanning the arbitrary area of the document exceeds the predetermined number. The processing unit 130 may notify that the document is in an inverted state when the number of times that the first pattern is not included in the scanned image exceeds the predetermined number.

For example, referring to (ii) of FIG. 4, the processing unit 130 scans the arbitrary areas 421 to 425 in the document 420, and the number of times that the first pattern is not included in the scan image formed is 5 or more It is possible to notify the blind person that the document 420 is in an inverted state by voice or vibration.

As described above, according to the embodiment of the present invention, when the position information of the barcode is not obtained in the scanned image, the current state of the document is informed through the sound so that the visually impaired person corrects the document according to the current state of the document Scan can be performed.

In addition, the determination unit 140 may determine whether a plurality of patterns including a direction pattern and a position pattern are included in the scan image formed by scanning the edge areas in the document. When the plurality of patterns are included, the processing unit 130 may determine movement information related to the in-document area corresponding to the shade position included in the position pattern as the scan area and notify.
