Next, processing will be described with reference to FIGS.
FIG. 15 is a flowchart showing the entire processing of the work management system. In FIG. 15, the overall outline of the process will be described. When the extraction start information is registered via the operation unit 16 of the management server (step S1), the management server 10 activates the work management system. The management server 10 extracts the quality information flag value 1 (defective product) from the quality management DB 92 and registers the extracted registration information to be extracted in the extracted product registration information DB 93. The management server 10 stores predetermined extracted product information in the extracted product registration information DB 93 in the extracted product information storage unit 90, and transmits the extracted product registration information to the tag scanning device 20 (step S2). Here, the extracted product registration information will be described as a tag ID (see FIG. 10).

  When receiving the extracted product registration information (step S3), the tag scanning device 20 scans the search area at predetermined time intervals (step S4). For example, scanning is performed at 1/60 second intervals. The tag scanning device 20 stores the scan information (see FIG. 11) in the storage unit 25, and the control unit 24 determines whether or not it matches the tag ID that is the extracted product registration information (step S5). If the tag scanning device 20 matches the tag ID (step S5, Yes), the corresponding scanning information (see FIG. 12) is transmitted to the management server 10 (step S6). If it does not match the tag ID (step S5, No), the process returns to step S4.

  On the other hand, when the management server 10 transmits a shooting start signal to the moving image device 40 in step S1, the moving image device 40 starts shooting (step S11). The moving image device 40 transmits the moving image information of the actual photograph from the camera 42 to the monitor 41 (step S12, step S14). In addition, the moving image device 40 transmits live-action moving image information (see FIG. 13) to the management server 10.

  When the management server 10 receives the moving image information of the live-action image from the video / video device 40, the management server 10 specifies a product by contour processing or the like based on the video / video data (step S13). On the other hand, when receiving the scan information from the tag scanning device 20 (Step S7), the management server 10 specifies the position information for each time of the extracted product. Then, based on the scan information and the moving image information of the live-action image, an extracted product on the live-action moving image is specified (step S8). The management server 10 transmits the extracted product information (see FIG. 14) to the video image device 40 (step S9).

  Upon receipt of the extracted product information (step S15), the moving image device 40 performs marking processing on the extracted product identified based on the extracted product information (step S16). As shown, the image is displayed on the monitor 41 (step S17).

  Note that the relationship between the tag scanning device 30, the management server 10, and the moving image device 50 is the same as the relationship between the tag scanning device 20, the management server 10, and the moving image device 40, and thus the description thereof is omitted. .

The work instruction processing will be described in detail with reference to FIG.
FIG. 16 is a flowchart showing processing of the management server. The same processes as those in FIG. 15 are denoted by the same reference numerals.

  In step S6, when the tag scanning device 20 transmits the position information of the extracted product and the time when the position information was acquired as scan information to the management server 10, the communication unit 13 of the management server 10 receives the scan information ( Step S20). When the scan information processing unit 87 receives the scan information from the moving image device 40 via the communication unit 13, the scan information processing unit 87 transmits the scan information to the scan information analysis unit 88 and the scan information storage unit 89 (step S21). Then, the scan information analysis unit 88 determines the position information of the extracted product from the scan information (step S22). The moving image storage unit 83 stores scan information (step S23).

  In step S12, the moving image video apparatus 40 transmits the moving image information of the real image captured by the camera 42 to the monitor 41, and the monitor 41 displays the moving image of the actual image (step S14). In addition, when the moving image video apparatus 40 transmits the moving image information of the live action to the management server 10, the communication unit 13 of the management server 10 receives the moving image information of the live action (Step S30). When the moving image processing unit 81 receives the moving image information of the real image from the moving image device 40 via the communication unit 13, the moving image processing unit 81 transmits the moving image information to the moving image analysis unit 82 and the moving image storage unit 83 (step S31). Then, the moving image analysis unit 82 extracts the object from the moving image information of the live-action image by outline processing or the like, and determines the position information of the object (step S32). The moving image storage unit 83 stores the moving image information of the live action (Step S33). When the respective position information in step S22 and step S32 is determined, the extracted product information storage unit 90 transmits the extracted product registration information to the determination unit 86 (step S23).

  The determination unit 86 extracts the extracted product from the extracted product registration information from the extracted product information storage unit 90, the position information of the extracted product from the scan information analysis unit 88, and the position information of the object from the moving image analysis unit 82. It is determined whether or not (step S24). If it is determined that the product is an extracted product (step S24, Yes), the extracted product monitoring processing unit 85 estimates the current position after α seconds (predetermined time) of the extracted product (step S25) and sends it to the editing unit 84. The editing unit 84 creates marking information based on the position information after α seconds, and transmits the marking information to the video image device 40 via the communication unit 13 (step S26). If it is not determined in step S24 that the product is an extracted product (step S24, No), the series of processing ends.

  The moving image device 40 performs marking processing based on the received marking information which is position information after α seconds (step S16), and displays the moving image marked on the moving image on the monitor 41 (step S17).
