That is, when registering a plurality of products of different types in the inspection device, the common image only needs to be registered once, and the setting work can be simplified and the setting time can be shortened.

Further, as shown in FIG. 12, the inspection device stores information on the normal image in the storage means. In the example shown in FIG. 12, the product number, product name, identification information (product code, etc.), product name image showing the product name, price image showing the price, sales promotion sticker image showing the sales promotion sticker, packaging material image showing the packaging material, pass / fail judgment Information indicating the determination condition of the above is stored in association with the storage means of the inspection device.
As shown in FIG. 12, the storage means of the inspection device stores the image information and the identification information in combination, so that the positive information about the product can be easily read out.
In the present embodiment, positive information = identification information (information such as a barcode) + normal image (image information), and normal image = unique image + common image.

In addition, the inspection device includes the product number, product name, identification information (product code, etc.), product name image, price image, sales promotion sticker image, packaging material image, information indicating the judgment conditions for pass / fail judgment, and the product name shown in FIG. Position information (area information) indicating each area of the image, the price image, the sales promotion sticker image, and the packaging material image may be associated and stored in the storage means.
The position information (region information) is defined based on, for example, a reference point of an image obtained by imaging an article by a photographing means. The reference point (origin) of the coordinates may be set at an arbitrary position of the captured image, for example, it may be the position of the lower left corner of the captured image, or a portion that serves as a mark of the captured product, in detail, the product. And the edge part of the background.
In the case of a rectangular image, the position information (area information) can be expressed by the coordinates of one point at the four corners and the coordinates of the diagonal position of that point. Further, in the case of a rectangular image, the position information (area information) can be expressed by the coordinates of one point at the four corners and the vertical size and horizontal size of the image.

In the example shown in FIG. 12, regarding the information indicating the judgment condition of the pass / fail judgment, when the condition is satisfied, the normal image stored in the storage means and the captured image obtained by imaging in the inspection mode are displayed. If it is determined that they match and the condition is not satisfied, the control unit determines that the normal image and the captured image do not match.
Specifically, in the case of the product number 001 shown in FIG. 12, the judgment conditions for pass / fail judgment are defined as [1] and [2], that is, the product name image as a unique image and the price image as a common image. It is specified by the combination. That is, when both the product name image showing this plum and the common image showing 100 yen match, the control unit determines that the normal image and the captured image match, and one or both match. If not, it is determined that the normal image and the captured image do not match.

Further, in the case of the product number 005 shown in FIG. 12, the judgment conditions for pass / fail judgment are defined as [1] [2] [3] / [1] [2], that is, the product name image as a unique image is common. It is defined by a combination of a price image as an image, a sales promotion sticker image as a common image, a product name image as a unique image, and a price image as a common image, and if the conditions are met, the normal image and the inspection mode It is judged that the captured images at the time match.

Further, in the case of the product number 009 shown in FIG. 12, the judgment conditions for the pass / fail judgment are [1] [2] / [1] [2] [3] / [1] [2] [4] / [1] [2]. ] [3] [4], that is, as in the above-mentioned example, when each of the conditions is satisfied, it is determined that the normal image and the captured image in the inspection mode match.

FIG. 13 is an example of a setting screen displayed on the operation input unit 25 as the second display area in the inspection mode. This setting screen has changing means 212A for changing the criteria for pass / fail determination of the inspection mode.
Specifically, the setting screen shown in FIG. 13 is an operation display unit (changing means 212A) indicating the presence / absence of the sales promotion sticker as the product number 31, the product name 32, and the table label LA (POP label) as information regarding the inspection target. , Judgment result 33 of the captured table label LA (displays the result of comparing the registered normal image and the captured captured image), display unit 34 showing the barcode reading result (reading result read by the code scanner). Display unit 35 indicating the registration code (displaying some digits of the identification information registered as positive information, this numerical value is compared with the reading result), display unit 36 indicating the reading code (reading) Of the results (34), only the digit portion to be compared with the positive information is displayed), and the display unit 37 showing the determination result (when both the imaging result and the reading result match the positive information, it is determined to be OK. The overall judgment result is displayed. If either information does not match, it is judged to be NG), the display unit 38 indicating the number of inspections (displaying the total number of inspections), and the display unit 39 indicating the number of NGs (comprehensive). The quantity whose judgment result was NG is displayed = the number discharged by the discharging means can be regarded as the number, and the passing button 310 (button for switching from the inspection mode to the passing mode. In the passing mode, the goods to be transported are judged. Since there is no such thing, it is not discharged.
It has an operation input unit such as (simply used when flowing an article) and an end button 311 (returns to a selection screen (not shown) for selecting an inspection target).
The display contents of each of the above display units (33 to 39) are updated each time one article is inspected.
The display unit 35 showing the registration code displays only the digit portion to be compared in advance among the identification information registered as the positive information. In the example of FIG. 13, the third to eighth digits of the total number of digits are compared. In addition, "*" in the numerical value indicates that any numerical value may be used. In the present embodiment, for example, when the changing means 212A is operated, a switching setting with or without a sales promotion sticker, that is, whether or not to include an image showing the sales promotion sticker is set as a condition for determining the pass / fail of the product. Can be done.

Although not shown, the changing means is configured so that whether or not to include the packaging material image can be set by a GUI (graphical user interface) which is substantially the same as the condition for determining the acceptance or rejection of the product.

FIG. 14 is a diagram showing an example of a screen for setting the threshold value of the correlation value.
Specifically, in the inspection mode, the camera-side control unit 11 of the control unit 10 is associated with a normal image stored in the storage means (camera control-side storage unit 13 or main control-side storage unit 23) and the normal image. As a process of comparing a unique image (an image showing a product name) or a common image (an image showing a price, an image showing a sales promotion sticker, etc.) with an image obtained by imaging an inspection object to be transported. , The correlation value calculation process for calculating the correlation value and the similarity calculation process for calculating the similarity are performed. In the present embodiment, the correlation value and the degree of similarity are expressed in%. That is, the correlation value is a numerical value expressing the degree of matching of each item to be collated in%.
If the calculated correlation value or similarity is equal to or greater than the set threshold value, the control unit determines that the captured product image and the normal image stored in the storage means are correlated, and displays OK. And so on. The larger the correlation value threshold, the more rigorous the test is processed (higher accuracy test is possible).
If the calculated correlation value or similarity is less than the set threshold value, the control unit determines that the captured product image and the normal image stored in the storage means do not correlate with each other. Performs NG processing such as NG display.

The correlation value or the threshold value regarding the similarity can be set for each product for each inspection, for each product name image, price image, sales promotion sticker image, and the like.
Specifically, as shown in FIG. 14, the threshold value of 80 is 80 for each of the image portion indicating the product name as the unique image, the image portion indicating the price as the common image, and the image portion indicating the sales promotion sticker as the common image. , 85, 80 (%). The control unit 10 such as the camera side control unit 11 and the main control unit 21 performs a process of changing the threshold value 50 based on a signal from an operation input unit such as the operation input unit 25 or the camera side display input unit 14.
For example, an image showing a product name or an image showing a sales promotion sticker contains characters, and an image showing a price contains numbers, and the numerical value calculates the correlation value with higher accuracy than the character. be able to. That is, it is preferable that the threshold value of the correlation value for the image showing the product name and the image showing the sales promotion sticker is set lower than the threshold value for the correlation value for the image showing the price.

Next, an example of the operation of the inspection device 100 according to the embodiment of the present invention in the inspection mode (ST11) will be described with reference to FIG. 15 and the like. In detail, from step ST11 onward, an example of the operation of the inspection device 100 in the inspection mode is shown. The inspection object w is provided with a front label LA on the front side and a back label LB on the back side.

In step ST12, in the inspection mode, the main control unit 21 performs a display process for prompting the main display input unit 24 to input the product type interlocking number. The user operates the main display input unit 24 to input the product type interlocking number.

In step ST13, the main control unit 21 reads out the product information (registration information) associated with the product type interlocking number from the main control side storage unit 23 based on the product type interlocking number input from the main display input unit 24. Specifically, the main control unit 21 reads product information (registration information) such as a product name and code information associated with the product type interlocking number from the main control side storage unit 23.
Further, the main control unit 21 outputs a signal indicating the start of the inspection mode and a signal indicating the product type interlocking number to the camera side control unit 11. Upon receiving the signal, the camera-side control unit 11 reads out the product name, the image of the price display area, the image of the product name display area, and the like associated with the product type interlocking number from the camera control-side storage unit 13.

In step ST14, when the operation of driving the belt conveyor is performed by the switch of the operation input unit 25, the main control unit 21 causes the endless belt of the belt conveyor 261 to move in a predetermined direction by the conveyor drive unit 26 such as a drive motor. Rotate.
The user places the product as the inspection object w on the mounting surface of the belt conveyor 261.
The belt conveyor 261 as a transport unit transports the inspection object w along the transport path in the transport direction.

In step ST15, in the inspection mode, the camera-side control unit 11 receives an instruction from the main control unit 21 and receives an instruction from the main control unit 21 to image the product label L, specifically the table label LA, which is the inspection target w, by the imaging unit 12. I do.
The camera-side control unit 11 includes an image captured by the image pickup unit 12, an image of a price display area associated with a product type interlocking number previously read from the camera control-side storage unit 13, an image of a product name display area, and the like. Compare with a normal image (captured image of a good product). Further, the camera-side control unit 11 displays an OK display on the camera-side display input unit 14 indicating that the captured image matches the normal image when they match as a result of the above comparison, and the images match. If not, a process of displaying an NG display indicating that the captured image does not match the normal image is displayed on the camera side display input unit 14, and a signal indicating the comparison result is output to the main control unit 21.

In step ST16, the code scanner 22 reads the code information printed on the back label LB of the inspection object w and outputs the code information to the main control unit 21.
The processes of steps ST15 and ST16 are processed in parallel by the camera-side control unit 11 and the main control unit 21.

In step ST17, the control unit 10 has registered information such as the product name and price in the captured image obtained by the imaging unit 12 and the code information read by the code scanner 22 in association with the product type interlocking number (registration information ( Compared with the image of the price display area in the normal image, the image of the product name display area, the code information, etc.), it is determined whether or not they match, and if they match, the process proceeds to step ST18 and the match occurs. If not, the process proceeds to step ST19.
Specifically, the camera-side control unit 11 displays a captured image of the front label LA of the inspection target, an image of the price display area of the positive image (captured image of a non-defective product) stored in advance, an image of the product name display area, and the like. After comparison, as shown in FIG. 16, a process of displaying the comparison result on the camera side display input unit 14 is performed, and a signal indicating the comparison result is output to the main control unit 21.
In the example shown in FIG. 16A, it is shown that the image of the price display area and the image of the product name display area match and match in the normal image and the captured image of the table label LA in the inspection mode. "OK" is displayed in the vicinity of each, and as a result of the determination based on the result, "OK" is displayed in the lower left portion of the screen.
In the example shown in FIG. 16B, in the inspection mode, the normal image of the front label LA and the captured image have printing defects such as print fading in the numerical value of the price display area of the captured image, and the price display area. "NG" indicating that the images of the above do not match is displayed in the vicinity, "OK" indicating that the images in the price display area match is displayed in the vicinity, and the judgment based on the result is made. As a result, "NG" is displayed in the lower left part of the screen.

Further, the main control unit 21 compares the code information displayed on the back label LB of the inspection object w with the positive code information (code information of a non-defective product) stored in advance.
Based on the reception result from the camera side control unit 11, the main control unit 21 matches the product information such as the price and price of the table label LA with a positive image (condition A), and is read by the code scanner. When the code information on the back label LB matches the positive code information (condition B), the inspection target w is judged to be a non-defective product and the process proceeds to step ST18, and either one of the A condition and the B condition or one of the B conditions is used. If both are not satisfied, the inspection target w is determined to be a defective product, and the process proceeds to step ST19.

In step ST18, the main control unit 21 determines that the inspection object w is a non-defective product, and as an OK process, performs a process of transporting the inspection object w to the next process area 300 by the belt conveyor 261 to perform the process of step ST21. move on.

In step ST19, the main control unit 21 determines that the inspection object w is a defective product, and performs a process of moving the inspection object w to the container 291 by the sorting unit 29 and temporarily storing it as an NG process, and the number of NGs. Is counted up, 1 is added to the number of NGs in detail (ST20), and the process proceeds to step ST21.
When the main control unit 21 determines that the inspection target object w is a defective product (NG), the main control unit 21 mainly captures an image (NG image) obtained by imaging the entire inspection target object w or a defective portion as NG processing. It may be stored in a storage means such as a control side storage unit 23 or a camera control side storage unit 13. Further, the control unit of the inspection device may transmit the NG image to the management device (computer) which is a higher-level device. This NG image is used as a reference for, for example, logging, confirmation processing after inspection, improvement of manufacturing process, and the like.

In step ST21, the number of inspections is counted up, specifically, 1 is added to the number of inspections.
Then, after performing the above-mentioned processing related to the inspection mode on a predetermined number of inspection objects w, the inspection mode is terminated and the process proceeds to the process of step ST1 shown in FIG.

For example, specifically, in the camera side display input unit 14, in conjunction with the process of setting the product name display area by the rectangular area and the process of setting the price display area, the main display input unit 24 sets the following settings. The switching means controls to switch the display contents so as to display the operation assist screen for the purpose.
That is, one of the two display areas is configured to have a master relationship, the other to have a slave relationship, or vice versa.

Further, in the inspection device 100 according to the embodiment of the present invention, the camera-side display input unit 14 (first display area) as the display means displays an image of the inspection article captured by the image pickup means (imaging unit 12). do. The inspection device 100 identifies the specific means 111 that specifies a unique image unique to one inspection article included in the image captured by the imaging means (imaging unit 12) and a common image common to a plurality of inspection articles. It has a storage means (camera control side storage unit 13, main control side storage unit 23) for storing a unique image or a common image specified by the means 111.

The identification means 111 identifies a unique image (an image showing a product name, etc.) and a common image (an image showing a sales promotion sticker, an image showing packaging material information, etc.) from an image obtained by imaging an inspection article by an imaging means. Perform processing. Further, as shown in FIGS. 9 and 10, the specifying means 111 shows the packaging material information by using the portion of the region indicating the product name or the like as a unique image from the image obtained by imaging the inspection article by the imaging means. The part of the area is used as a unique image.

Further, the storage means (camera control side storage unit 13, if necessary, main control side storage unit 23) of the inspection device according to the embodiment of the present invention stores a normal image by combining a unique image and a common image. The inspection device 100 has a comparison means 112 for comparing an inspection image obtained by imaging an inspection article with an imaging means and a normal image stored by a storage means.
In detail, the criteria for comparison by the comparison means differ for each product depending on the combination of the specified unique image and the common image.
For example, in the registration mode, when the product "salmon" is imaged in a state where the storage means of the inspection device does not store a common image, "salmon" (an image showing the product name) which is a unique image of the product "salmon"). It is possible to perform a process of specifying the image and store the unique image (product name image) in the storage means.
Furthermore, if a promotional sticker indicating the "new product" is affixed to the product "salmon" onigiri, the "new product" can be obtained from the image obtained by capturing the product "salmon" with an imaging means in the registration mode. The image of the seal portion can be specified and extracted, and the image of the extracted portion can be stored in the storage means as a common image.
The feature of the common image is that, for example, the common image of "new product" can be reused not only for the product "salmon" but also when registering the regular image of other products. ..
Further, as a common image, for example, an image showing a price (price image) and an image showing a packaging material (packaging material image) can also be commonly used when registering other products.

As a specific merit of using the common image, for example, when the price image, the sales promotion sticker image, and the packaging material image are already stored in the storage means as the common image, the normal image of the product "Negitoro" is displayed in the registration mode. When registering, only the part of "Negitoro" indicating the product name is specified and extracted from the captured image obtained by imaging the product "Negitoro", and the product name image is used as a unique image for the product "Negitoro". It is stored in the storage means in association with the product number, product name, etc. of "Toro".
Then, the product "Negitoro" is associated with the price image, the sales promotion sticker image, and the packaging material image of the common image. That is, it is not necessary to identify and extract parts such as price, sales promotion sticker, and packaging material from the captured image, the processing required for registration is reduced, and the product "Negitoro" can be registered in a short time.
Further, the inspection apparatus according to the embodiment of the present invention does not need to capture a normal image as many as the number of variations of the inspection, and can reuse a common image for inspection of different types of inspection articles. By combining the common images, it is possible to generate a plurality of variations of normal images (images that serve as criteria for pass / fail determination), and it is possible to reduce the number of times the normal images are captured, the common image setting process, and the like.

Further, the inspection device 100 according to the embodiment of the present invention shows a combination of a unique image of a normal image and a common image stored by storage means (camera control side storage unit 13 and main control side storage unit 23). It has a changing means 212 for changing the combination information.
At the time of inspection, in the second display area (main display input unit 24), the display part of "without sales promotion sticker" is an operable button, and when this button is operated, "with sales promotion sticker" and "promotion". The control unit controls so that the displayed content is switched to "No seal". Specifically, the changing means 212 changes the acceptance criteria (judgment criteria) depending on whether there is a "promotional sticker" or no "promotional sticker".

Further, the comparison means 112 of the inspection device according to the embodiment of the present invention is based on the comparison between the inspection image obtained by imaging the inspection article by the imaging means and the normal image stored in the storage unit.
