Many users choose not only the design and price, but also the type of CPU and OS, and before shipping the personal computer, it is confirmed that the correct label is stuck in the correct position. As a method for confirming the label, a person visually confirms whether or not the pattern of the label attached to the personal computer matches the type of CPU or OS installed in the personal computer. . However, there are currently 16 types of labels for CPUs and 5 types of labels for OSs, and different versions of labels from the same manufacturer have similar patterns, so that visual confirmation errors and omissions may occur. There's a problem.

In this regard, an inspection method is known in which an object to be tested that is carried on a belt conveyor is photographed and the pattern of the photographed image is analyzed for inspection. For example, in Patent Document 1, a barcode for identifying a model or the like is pasted on the object to be tested, and the pattern of the photographed image is identified by photographing the object to be tested and reading the barcode. A technique for determining whether or not it is of a model is described, and Patent Document 2 is obtained by reading a barcode when photographing after reading the barcode on the object to be tested. Describes a technique for controlling the photographing method according to the information. Applying these technologies, a barcode for identifying the type of CPU or OS is affixed to the personal computer, and the pattern of the photographed image obtained by photographing the label on the personal computer is identified by reading the barcode. By automatically determining whether or not the CPU and OS match, the inspection accuracy can be improved and the inspection labor can be saved.

  FIG. 6 is a top view of the personal computers 10_1 and 10_2 mounted on the belt conveyor 500 shown in FIG.

  As shown in FIG. 6, labels 50 are attached to the personal computers 10_1 and 10_2 at different positions. The personal computers 10_1 and 10_2 are assigned management numbers for identifying the personal computers 10_1 and 10_2. A bar code indicating the management number is placed beside the label 50 of each personal computer 10_1 and 10_2. A printing paper 60 on which 61 is printed is placed. The barcode 61 corresponds to an example of a code in the present embodiment, corresponds to an example of a barcode in the present embodiment, and the printing paper 60 corresponds to an example of a printed matter in the present embodiment.

  FIG. 7 is a diagram illustrating a position where the printing paper 60 is placed.

  In the label inspection system 1 shown in FIG. 1, the personal computer 10 placed on the belt conveyor 500 moves in the direction of arrow A. The tester places the printing paper 60 so that the barcode 61 is arranged at a position that is a predetermined distance away from the label 50 affixed to the personal computer 10 in the traveling direction (arrow A direction). In the present embodiment, the position of the barcode 61 on the printing paper 60 is determined in advance, and the printing paper 60 is placed so that the left edge of the printing paper 60 is arranged at a position about 1 cm away from the right edge of the label 50. Placed. In the example shown in FIG. 7A, since the CPU label 51 and the OS label 52 are pasted in the vertical direction on the right end portion of the personal computer 10, the printing paper 60 is about 1 cm from the CPU label 51 and the OS label 52. In the example shown in FIG. 7B, the CPU label 51, the OS label 52, and the graphic hardware label 63 are pasted in the horizontal direction on the left end portion of the personal computer 10 in the example shown in FIG.

And a serial code unique to each personal computer 10 (for example, R7Y00006), a model, a model name, and a management number (for example, a nine-digit code) uniquely determining the serial code.

  FIG. 8 is a diagram illustrating the arrangement position of the label 50, and FIG. 9 is a diagram illustrating the distance between the label 50 and the camera 200.

  Each personal computer 10 has a label area to which a label 50 is attached, and a plurality of labels 50 are arranged in the label area. FIG. 8 shows a plurality of divided areas P1 to P9 obtained by dividing the label area, and the plurality of labels 50 are attached to the divided areas P1 to P9.

  Since the distance between the camera 200 and the belt conveyor 500 is fixed, as shown in FIG. 9, the camera 200 is based on the height h of the personal computer 10 to the surface on which the label 50 is attached. The distance X between the label 50 and the label 50 can be calculated.

  In the expected value data in the correct answer data, a label number for identifying the label 50 to be attached to each of the divided areas P1 to P9 shown in FIG. 8 (however, “−1” is set in the area to which the label 50 is not attached). ) And the height h up to the surface on which the label 50 shown in FIG. 9 is attached. For example, when the expected value data is “12, −1, −1, 2, −1, −1, −1, −1, −1, 32”, the label number “12” is assigned to the divided region P1 shown in FIG. ", A label 50 with a label number" 2 "is attached to the divided region P4, and the height h shown in FIG. 9 is" 32 ".

  The storage device 400 also stores a label table for associating the label number in the correct data with the label picture.

  FIG. 10 is a conceptual diagram of a label table stored in the storage device 400.

  As shown in FIG. 10, the label table associates a label number for identifying each label 50, a figure number representing the design of the label 50, an image of the label 50, and the width and length of the label 50.

  Next, label inspection processing in the label inspection system 1 will be described.

  FIG. 11 is a flowchart showing the flow of label inspection processing in the label inspection system 1.

  In the following, each element of the label inspection system 1 shown in FIGS. 1 and 4 will be described in detail by explaining the flow of the label inspection process according to the flowchart of FIG.

  As shown in FIG. 7, the personal computer 10 is placed on the belt conveyor 500, and a management number for identifying each personal computer 10 is shown on the right side of the label 50 attached to the personal computer 10 by the tester. A printing paper 61 on which a barcode 60 is printed is arranged. In label inspection, first, the barcode on the printing paper 61 is read by the barcode reader 300, and the management number is identified (step S11 in FIG. 11). The identified management number is transmitted to the barcode acquisition unit 710 shown in FIG.

  When the barcode acquisition unit 710 acquires the management number from the barcode reader 300, the barcode acquisition unit 710 transmits the management number to the correct data acquisition unit 720 and issues a shooting start trigger toward the shooting instruction unit 730.

  When receiving a shooting start trigger, the shooting instruction unit 730 transmits a shooting instruction to the camera 200.

  Upon receiving the shooting instruction, the camera 200 takes a picture of the personal computer 10 with the shutter turned off (step S12 in FIG. 11). As shown in FIG. 7, the printing paper 61 is arranged at a position spaced a predetermined distance (about 1 cm) from the right end of the label 50 attached to the personal computer 10, and at a timing when the barcode 60 is recognized. By issuing the shooting start trigger, it is possible to reliably shoot the label 50 on the personal computer 10 without the trouble and burden of moving the personal computer 10 itself. Step S12 for photographing the personal computer 10 corresponds to an example of an imaging unit in the present embodiment. The captured image is transmitted from the camera 200 to the captured image acquisition unit 740 and further transmitted to the label recognition unit 750.

  Further, the correct answer data acquisition unit 720 acquires correct answer data including the management number obtained by reading the barcode 60 on the printing paper 61 and the label table from the storage device 400 (step S13 in FIG. 11). . Step S13 for obtaining correct data based on the management number corresponds to an example of an information obtaining unit in the present embodiment. The correct data and the label table are transmitted from the correct data acquisition unit 720 to the label recognition unit 750.

  The label recognizing unit 750 recognizes the label appearing in the captured image (step S14 in FIG. 11).

  FIG. 12 is a flowchart showing the flow of the label recognition process shown in step S14 of FIG.

  In the label recognizing unit 750, first, the brightness and contrast of the captured image are adjusted (step S31 in FIG. 12).

  Subsequently, the distance X between the camera 200 and the label surface is calculated based on the height h in the correct answer data shown in FIG. 9, and the size of the label image in the photographed image is determined based on the distance X. Then, an expected value image ratio indicating how much is the actual size of the label 50 is calculated (step S32 in FIG. 12).

  Further, the captured image is subjected to binarization processing, and the contour line in the binarized image is extracted (step S33 in FIG. 12). From the extracted contour lines, the contour image is the contour line of the label image. The estimated label candidate lines are extracted (step S34 in FIG. 12).

  When the label candidate line is extracted, the label candidate image surrounded by the label candidate line in the original photographed image is extracted. Further, the label image in the label table shown in FIG. 10 is enlarged / reduced at the expected value image ratio calculated in step S32, and the similarity between the label candidate image and the label image after the size change is calculated. When the similarity is equal to or greater than a predetermined threshold (step S35 in FIG. 12: Yes), it is determined that the label candidate image is a label image (step S36 in FIG. 12). The similarity calculation process with the label candidate image is performed for all the label images. When a plurality of label candidate images are extracted, label recognition processing is performed on all label candidate images.

  FIG. 13 is a diagram illustrating an example of a captured image when it is determined that there is an error in the label inspection.

  As shown in FIG. 13A, when the printing paper 61 is not arranged at the correct position with respect to the label 50, the label is out of the shooting angle of view without matching the shooting timing, and the label candidate line is displayed in step S34. Is not extracted and is determined to be an error.

  Further, as shown in FIG. 13B, even when the personal computer 10 is not arranged with only the printing paper 61, the label candidate line is not extracted, so that it is determined as an error.

  When the determination process is completed for all label candidate images (step S37 in FIG. 12: Yes), the label recognition result is transmitted to the determination unit 760. Step S14 in FIG. 11 for executing the label recognition process corresponds to an example of a symbol recognition unit in the present embodiment.

  Returning to FIG.

  When the label image is recognized (step S15 in FIG. 11: Yes), the determination unit 760 first detects an overlap between the recognized label images. If the label images overlap (step S16 in FIG. 11: Yes), the label image with the higher similarity is selected (step S17 in FIG. 11).

  Subsequently, the label number of the recognized label image is acquired based on the label table, and the label number included in the expected value data in the correct answer data is acquired. Further, by comparing them, it is determined whether or not the type of the label 50 attached to the personal computer 10 is correct (step S18 in FIG. 11). For example, as shown in FIG. 13C, when a picture label 55 that is not in the label table shown in FIG. 10 is attached to the personal computer 10, it is determined that an error occurs because the type of the label 50 does not match. Is done. Also, as shown in FIG. 13D, when paper 80 or the like is placed on the label 52, the label image of the label 52 is not recognized, and therefore an error determination is made that the label type does not match.

  When the type of the label 50 attached to the personal computer 10 is correct (step S18 in FIG. 11: Yes), the label 50 has a plurality of divided areas P1 to P9 shown in FIG. 8 based on the expected value data in the correct answer data. It is determined whether or not it is pasted at the correct position (step S19 in FIG. 11). As shown in FIG. 13E, when the labels 51 and 52 are pasted on the wrong divided areas P1 to P9, or when pasted outside the divided areas P1 to P9, an error occurs in step S18. Judgment is made.

  When the label 50 is pasted at the correct position (step S19 in FIG. 11), it is determined whether or not the number of labels is correct (step S20 in FIG. 11). For example, when a plurality of the same labels are pasted, it is determined as an error in step S20.

  If it is determined that the number of labels is correct (step S20 in FIG. 11), it is determined that the correct label is attached at the correct position on the personal computer 10 (step S21 in FIG. 11).

  Further, the label image is not identified (step S15 in FIG. 11: No), the type of the label 50 is not correct (step S18: No in FIG. 11), or the position of the label 50 is not correct (FIG. 11). If the number of labels 50 is not correct (step S20: No in FIG. 11), an error message is displayed on the display screen of the control computer 100 by the error notification unit 770.

  As described above, according to this embodiment, it is possible to reduce the burden on the tester and accurately determine whether or not the correct label 50 corresponding to the type of CPU or OS is attached to the correct position on the personal computer 10. Can be inspected.
