The PC 3 is installed in an office of a distribution center or the like, and the user can browse the images of the sorting area taken by the cameras 1a and 1b in real time on the monitor screen displayed on the monitor 7, The video of the past sorting area recorded in the recorder 2 can be browsed.

  Next, the layout of the sorting area and the installation status of the cameras 1a and 1b will be described. FIG. 2 is a plan view of the sorting area showing the layout of the sorting area and the installation status of the cameras 1a and 1b.

  In the sorting area, sorting work is performed in which products such as clothing are sorted into crate (container) 21 prepared for each destination store based on the work slip. The crate 21 is arranged side by side in one direction, and one work area is formed by two rows of the crate 21 and a passage between them. Workers A to E enter the work area while pushing the transport cart 22 after loading the same amount of goods stored in a warehouse not shown in the work slip onto the transport cart 22. The products loaded on the transport carriage 22 are sequentially put into the crate 21 of the shipping destination store described in the work slip.

  In the present embodiment, a plurality of work areas are set in the sorting area, and workers A to E take charge of each work area one by one. In the example shown in FIG. 2, first to fifth work areas (area No. 01 to No. 05) are set in the sorting area, and these five work areas are assigned to five workers A to E. Are in charge of each.

  In the present embodiment, the first and second cameras 1a and 1b are arranged for each work area. The 1st camera 1a is arrange | positioned at the entrance / exit of a work area, and can image | photograph the workers A-E which go in and out of a work area. The second camera 1b is arranged on the side opposite to the entrance / exit of the work area so as to overlook the passage in the work area, and can photograph the workers A to E who perform sorting work in the work area. .

  In the present embodiment, the first camera 1a captures both the workers A to E when entering the work area and the workers A to E when leaving the work area. However, you may make it image | photograph worker AE at the time of approaching into a work area with the 2nd camera 1b.

  Next, work slips used in sorting work will be described. FIG. 3 is an explanatory view showing a work slip used in the sorting work.

  This work slip describes the work contents of the sorting work, and is used when sorting a necessary quantity of one kind of product carried out from the warehouse for each store of the shipping destination. In the work slip, as the information for identifying the sorting work, the sorting work number, the name of the work area, and the barcode of the sorting work number are described. In addition, the work slip includes a product code, a product number, a product quantity (total number), a number of shipping destination stores, and a product name as information about the product to be sorted. The work slip includes a store code, a quantity of goods, and a store name for each store of the shipping destination as information on the shipping destination store.

  A work slip is created for each work area, and the shipping destination store described in one work slip corresponds to the crate 21 for each shipping destination store arranged in one work area, and the worker works By entering the area and performing the sorting work according to the sorting contents (ship destination store and quantity) described in the work slip, one sorting work is completed. In this embodiment, based on one work slip The sorting work performed in this way is defined as one work item.

  Next, the procedure of the work management process performed by the PC 3 shown in FIG. 1 will be described. FIG. 4 is an explanatory diagram for explaining the procedure of work management processing performed by the PC 3.

  In this embodiment, since the sorting work is performed in the work area, it can be considered that the worker has started work by entering the work area, and the worker can leave the work area. It can be considered that the work has been completed. Therefore, the first camera 1a takes a picture of the worker at the time of entering the work area, that is, the worker at the time of starting the work, and the worker at the time of leaving the work area, that is, the worker at the time of finishing the work, A first worker image in which the worker at the start of the work is shown and a second worker image in which the worker at the end of the work is shown can be acquired.

  Here, when entering the work area, by turning the cameras 1a and 1b toward the worker, the first worker image in which the worker's face is reflected can be acquired. Further, when leaving the work area, the operator turns the cameras 1a and 1b to turn around and presents the work slip to the worker, specifically, the operation of raising the work slip in front of the chest. Thus, the work slip is photographed together with the worker's face, and a second worker image in which the worker's face and the work slip are captured can be acquired.

  When the first and second worker images are acquired in this way, a person verification is performed by recognizing a person from each worker image and determining whether or not both persons are the same person. If this person verification is successful, it can be determined that one worker has performed sorting work in the work area. Then, with the shooting time of the first worker image as the work start time and the shooting time of the second worker image as the work end time, the work time required for the sorting work is determined from the work start time and the work end time. Can be acquired. In addition, the work area can be specified from the cameras 1a and 1b that have captured the worker images.

  Also, a work slip, in particular a partial image showing the sorting work number, is extracted from the second worker image, and OCR (optical character recognition) is performed on this partial image, so that the sorting work number (work item Identification information) can be acquired. Thereby, the work slip (work item) processed by the worker is specified.

  In this embodiment, the work slip is presented to the worker at the end of the work, but the work slip is presented at the start of the work, or the work slip is presented at both the start and end of the work. May be.

  In this embodiment, a work slip is prepared for each work area, and one worker is assigned to a predetermined work area one by one. However, the worker who is responsible for the work area is not predetermined. That is, the worker may appropriately receive the work slip and perform the sorting work in the work area described in the work slip. Even in such a case, the worker who has processed the work slip can be specified, and the work time for each work slip (work item) can be acquired.

  In the present embodiment, the work start time and the work end time are acquired from the shooting times of the first and second worker images, but the sorting is performed based on the images of the workers performing the sorting work. You may make it acquire the time in the middle of work, and measure the elapsed time in each stage of sorting work.

  In addition, when photographing the worker with the first camera 1a, it is desirable not to allow the worker to perform extra operations such as button operations. For example, the first camera 1a is always photographed. If an image suitable for person verification can be acquired from the images, the operator may be informed that the shooting has been completed normally by lighting the lamp or a notification sound from the speaker.

  Next, work management processing performed by the PC 3 shown in FIG. 1 will be described in detail. FIG. 5 is a functional block diagram showing a schematic configuration of the PC 3.

  The PC 3 includes a first image acquisition unit 31, a second image acquisition unit 32, a work time measurement unit 33, a work recognition unit 34, an implementation information generation unit 35, and an input / output control unit 36. ing.

  The first image acquisition unit 31 acquires a first worker image showing a worker at the time of starting work related to one work item, that is, work on one work slip. In the present embodiment, the first camera 1a (see FIG. 2) takes a picture of a worker entering the work area, and the time when the worker enters the work area is regarded as the time when the work is started. A first worker image is acquired from the video imaged by 1a and stored in the recorder 2.

  The second image acquisition unit 32 acquires a second worker image showing the worker at the time when the work related to one work item is completed. In the present embodiment, the first camera 1a (see FIG. 2) takes a picture of a worker leaving the work area, and the time when the worker leaves the work area is regarded as the time when the work is finished. A second worker image is acquired from the video imaged by 1a and stored in the recorder 2.

  Here, in this embodiment, since the workers at the start and end of work are photographed with one camera 1a, 1b, whether the photographed worker is at the start of work or at the end of work. Need to be determined. For this purpose, the first and second image acquisition units 31 and 32 perform a person tracking process for tracking the detected person in addition to the person detection process for detecting a person from the video, and the movement direction of the person is determined. What is necessary is just to detect and discriminate | determine whether it is at the time of work start and work end based on this moving direction.

  Note that it is possible to shoot the workers at the start and end of work separately by the two cameras 1a and 1b. In this case, the start and end of work are determined by the captured cameras 1a and 1b. Therefore, it is not necessary to detect the moving direction of the person.

  The work time measurement unit 33 performs image analysis on the first and second worker images acquired by the first and second image acquisition units 31 and 32 and is required for work related to one work item. Processing for measuring the working time is performed.

  That is, the work time measuring unit 33 includes a person collation unit 37. The person collation unit 37 performs person collation between the persons shown in the first and second worker images by image analysis. If the collation is successful, it is determined that one worker has performed sorting work in the work area, the shooting time of the first worker image is set as the work start time, and the shooting time of the second worker image is set as the shooting time. As the work end time, the work time is calculated from the work start time and the work end time.

  In the person verification process, it is sufficient to recognize each person in the first and second worker images and determine whether both persons are the same person, but the worker is registered in advance. The person may be identified by performing person verification between the registered worker and the person recognized from the worker image. In this way, since a person who is not registered as an operator can be detected, an advantage of ensuring security can be obtained.

  For the person collation process, a known person recognition technique may be used. For example, feature amount data extracted from two worker images may be compared to determine whether or not they are the same person.

  The work recognition unit 34 performs image analysis on at least one of the worker images acquired by the first and second image acquisition units 31 and 32 to recognize a work item performed by the worker. . In the present embodiment, as described above, the work item is recognized by the work slip (display object) presented by the worker. In the present embodiment, in order to present the work slip to the worker when leaving the work area, the second work image obtained by the second image obtaining unit 32 is subjected to image analysis to obtain a work item. Recognize

  In the present embodiment, as the image analysis, OCR is performed to read the sorting work number described in the work slip, and thereby the sorting work number is acquired. In this image analysis, the image area of the work slip is detected from the worker image, and further, a partial image showing the sorting work number in the image area of the work slip is extracted, and OCR is performed on the partial image. Get the sorting work number.

  The collation result display unit 57 includes, as collation result information, identification information (ID and EnID), person similarity (Score) between the face images at the start and end of work, The time from the time when the worker was detected to the time when the worker was first collated at the end of the work (Time1) and the time from the time when the worker was first detected at the start of the work to the time when the worker was last collated (Time2) Is displayed.

  With this person verification screen, the user can confirm the status of the person verification process performed by the person verification unit 37, that is, whether or not the person verification process has been appropriately performed.

  Next, the implementation information generated by the implementation information generation unit 35 illustrated in FIG. 5 will be described. FIG. 7 is an explanatory diagram showing implementation information generated by the implementation information generation unit 35.

  The execution information generation unit 35 performs processing for generating execution information related to the execution status for each worker and work item based on the measurement result by the work time measurement unit 33 and the recognition result by the work recognition unit 34. In the present embodiment, each worker is responsible for one work area, and the execution information generating unit 35 uses a predetermined target period (time zone, 10:10) for each work area and worker as the execution information. 00-12: 15), the work start time, work end time, and work time (required time) for each work voucher (work item), the average work time per work voucher, and the work for which the sorting work has ended. The number of slips (number of processed sheets) is acquired.

  Next, the list display information generated by the display information generation unit 42 shown in FIG. 5 will be described. FIG. 8 is an explanatory diagram showing a list display screen displayed on the monitor 7.

  In the present embodiment, the display information generating unit 42 performs processing for generating and outputting list display information for displaying a list of information on the implementation status for each worker and work item in the target period. A list display screen is displayed on the monitor 7.

  This list display screen is provided with a date and time designation unit 61 and a list display unit 62. The date / time specifying unit 61 is for the user to specify a date and a time zone. The list display unit 62 displays a graph 63 and a list 64 representing the implementation status of the date and time period specified by the date and time specifying unit 61.

  In the graph 63, the work time (required time) for each work slip (work item) is displayed as a bar graph for each worker, and the average work time (average required time) per work slip is displayed as a line graph. . In the list 74, numerical values of the work time and the average work time for each work slip displayed in the graph 63 are displayed.

  By comparing the work time of each worker in the graph 63 and the list 64, the work efficiency for each worker can be grasped. In the example shown in FIG. 8, it can be seen that the work efficiency of the worker C is low and the work efficiency of the workers A and D is high. For workers with low work efficiency, the information displayed on the list display screen can be presented to the workers, thereby raising awareness of sorting work. In addition, when the work efficiency is low regardless of the worker in a specific work area, the arrangement of the crate 21 is not appropriate, and it is assumed that time is required for the sorting work. That's fine. In addition, since the work efficiency for each worker can be grasped, appropriate personnel management can be performed in consideration of the work efficiency for each worker.

  In the present embodiment, the list display information generated by the display information generation unit 42 is output by the monitor 7, but may be output by a printer (not shown).

  Further, in the example shown in FIG. 8, in order to easily compare the work efficiency of each worker, the work time is displayed in order from the first one of the work slips, but actually the work contents differ for each work slip. In many cases, it is necessary to grasp the work efficiency of each work item. Therefore, in this embodiment, since the work slip processed by the worker can be specified, a standard work time determined in advance according to the work amount (such as the quantity of goods and the number of shipping destinations) known from the work slip, Thus, the work efficiency of each worker can be compared in detail using the work evaluation values (shortening time, delay time, etc.) of each worker.

  Next, a video display screen for confirming the actual work status will be described. FIG. 9 is an explanatory diagram showing a video display screen displayed on the monitor 7.

  In the present embodiment, the display information generation unit 42 performs a process of displaying a video that captures the work status related to the work item in response to an input operation of the user who selects the work item on the list display screen (see FIG. 8). As a result, the video display screen shown in FIG. 9 is displayed on the monitor 7. In particular, in the present embodiment, an operation for selecting one work item of a worker of interest on the list display screen is performed. Specifically, on the graph 63 or the list table 64, the work time ( When the user clicks the part where the required time is displayed with the mouse, a video display screen is displayed in a pop-up on the list display screen.

  On this video display screen, a video display 71 and operation buttons 72 are provided. The video display 71 displays a video (moving image) that captures one work item selected on the list display screen, that is, the work status of the sorting work related to one work slip. In the present embodiment, the second camera 1b (see FIG. 2) captures the worker who performs the sorting work in the work area, and the image captured by the second camera 1b is displayed. The

  Thereby, it is possible to observe the work status of the worker in the work area. In addition, when the video is reproduced, it is only necessary to operate the operation button 72. By using the operation button 72, in addition to normal reproduction, fast forward reproduction and rewind reproduction can be performed. Can be observed.

  Next, another example of the arrangement of the cameras 1a and 1b will be described. FIG. 10 is a plan view of an essential part of the sorting area for explaining another example of the arrangement of the cameras 1a and 1b.

  In the example shown in FIG. 2, when the first camera 1a enters the work area, that is, when the work starts, and when the first camera 1a leaves the work area, that is, when the work is finished. In the example shown in FIG. 10, the first camera 1a photographs the worker when entering the work area, and the second camera 1b is taken from the work area. The worker is photographed at the time of leaving.

  Specifically, the first camera 1a is arranged on the side opposite to the entrance / exit of the work area, and the second camera 1b is arranged on the entrance / exit side of the work area. The first camera 1a is arranged so as to overlook the passage in the work area, can photograph the worker entering the work area from the front, and further photographs the worker who performs the sorting work in the work area. be able to. The second camera 1b is also arranged so as to overlook the passage in the work area, can photograph the worker leaving the work area from the front, and further identifies the worker who performs the sorting work in the work area as the first. Can be taken from the side opposite to the camera 1a.

  As described above, when the worker entering the work area and the worker leaving the work area are separately photographed by the two cameras 1a and 1b, the worker is at each timing at the start of the work and at the end of the work. Can be taken from the front, so that it is not necessary for the operator to perform an extra operation of turning the camera 1a, 1b, so that the burden on the operator is reduced and work efficiency is increased. Can do.

  In this embodiment, the example in which the entrance and exit of the work area are the same has been described. However, the entrance and exit of the work area may be different. In this case, the cameras 1a and 1b are respectively provided at the entrance and the exit. What is necessary is just to arrange.

  As described above, in the present embodiment, the first image acquisition unit 31 acquires the first worker image showing the worker at the start of work, and the second image acquisition unit 32 performs the work at the end of the work. The second worker image in which the worker is photographed is acquired, and the work time measuring unit 33 performs image analysis on the first and second worker images to obtain the work time required for work related to one work item. The work recognizing unit 34 performs image analysis on at least one of the first and second worker images to recognize a work item, and the execution information generating unit 35 recognizes the work time measuring unit 33. Is generated based on the measurement result by the user and the recognition result by the work recognizing unit 34, and information regarding the implementation status for each worker and work item is generated. Every Display information for displaying information related to the implementation status is generated and output. Based on the first and second worker images, the worker who performed the work is specified, and the work time of the worker is determined. Since the work item is recognized, it is possible to generate and output information on the work execution status for each worker and work item. And since it is not necessary to make a worker input the information regarding a work item by operating a terminal etc., it can avoid that work efficiency falls.

  In the present embodiment, the worker image used in the work recognition unit 34 is assumed to be a display object that identifies a work item together with the worker, and the work recognition unit 34 captures the display object in the worker image. Since the image analysis is performed on the partial image to recognize the work item, and the work item is recognized based on the display object for specifying the work item, the work item can be recognized with high accuracy.

  In the present embodiment, the display object is a work voucher in which information about the work content is described, and the worker image used in the work recognition unit 34 is shown in a state where the work voucher is presented by the worker. The work slip is necessary for the worker to perform the work, and the work item is recognized by the work slip, so that it is not necessary to prepare a special display object for recognizing the work item.

  In the present embodiment, since the display information generating unit 42 generates and outputs list display information for displaying a list of information on the execution status for each worker and work item in the target period, the worker and work item are output. The user can grasp the implementation status of each at a glance. In particular, by comparing the work time for each worker, the user can grasp the work efficiency of each worker, and by comparing the work time for each work item, the user can see the difference between work items. I can grasp it.

  Further, in the present embodiment, in the display information generation unit 42, an image of the work situation related to the work item is captured in accordance with the input operation of the user who selects the work item on the screen on which the list display information is displayed on the monitor 7. Since the display is made, it is possible to confirm the actual work status of the worker by the video, and thereby, the problem of the worker and the work item can be specifically grasped.

  For example, for workers with low work efficiency, it is possible to examine the factors that cause low work efficiency by observing the work status with video, and for workers with high work efficiency, the work status is displayed with video. By observing it, it becomes possible to examine an efficient work procedure, and the overall efficiency can be improved by reflecting the knowledge obtained by these examinations in the guidance of the worker.

  As mentioned above, although this invention was demonstrated based on specific embodiment, these embodiment is an illustration to the last, Comprising: This invention is not limited by these embodiment. In addition, all the components of the work management device, the work management system, and the work management method according to the present invention described in the above embodiment are not necessarily essential, and are appropriately selected as long as they do not depart from the scope of the present invention. It is possible.

  For example, in the present embodiment, an example of sorting work performed at a distribution center, in particular, sorting work of products stored in a warehouse by shipping destination store has been described. However, an article that is a target of the sorting work is an article other than a product. For example, it may be a package such as a parcel collected from the client. Furthermore, the work to be managed is not limited to such sorting work, and can be similarly applied to work other than sorting work such as assembly work performed in a manufacturing factory.

  Further, in this embodiment, the display object for specifying the work item is a work slip, but the display is not limited to the work slip. For example, a worker's hat, clothes, name tag, and the like are possible. However, since a color, a shape, etc. differ for every work, a work item can be identified.

  In the present embodiment, the person tracking process is performed by the PC 3, but the person tracking process may be configured by an apparatus different from the PC 3. It is also possible to configure a camera with a person tracking function by mounting a person tracking function on the cameras 1a and 1b.

  Further, in the present embodiment, the processing necessary for work management is performed by the PC 3 provided in the store. However, as shown in FIG. 1, the necessary processing is performed by the PC 11 or the like provided in the headquarters. The cloud computer 12 constituting the cloud computing system may be made to perform the operation. In addition, necessary processing may be shared by a plurality of information processing apparatuses, and information may be transferred between the plurality of information processing apparatuses via a communication medium such as an IP network or a LAN. In this case, a work management system is composed of a plurality of information processing apparatuses that share necessary processing.

  In such a configuration, it is preferable to cause the PC 3 provided in the store to perform at least a process with a large calculation amount among processes necessary for work management, for example, a person detection process. With this configuration, the amount of information required for the remaining processing can be reduced, so that the remaining processing is performed by an information processing apparatus installed at a location different from the store, for example, the PC 11 installed at the headquarters. Even if it does in this way, since communication load can be reduced, operation of the system by a wide area network connection form becomes easy.

  In addition, among the processes necessary for work management, at least a process with a large calculation amount, for example, a person detection process may be performed by the cloud computer 12. If comprised in this way, since the amount of calculations of the remaining processes may be small, a high-speed information processing apparatus will become unnecessary for users, such as a shop, and the cost which a user will bear can be reduced.

  In addition, the cloud computer 12 may perform all necessary processes, or at least display information generation processing among necessary processes may be shared by the cloud computer 12. In addition to the PCs 3 and 11 provided in the mobile phone, it is possible to display information related to work implementation status on a portable terminal such as the smartphone 13 or the tablet terminal 14. You can check the status of work at any location.

  Further, in the present embodiment, the PC 3 installed in the store performs processing necessary for work management, and the GUI screen is displayed on the monitor 7 of the PC 3 to perform necessary input and output on the PC 3. However, the necessary input and output may be performed by an information processing apparatus different from the information processing apparatus that performs processing necessary for work management, for example, a portable terminal such as the PC 11 or the tablet terminal 14 installed in the headquarters. .

  The work management device, the work management system, and the work management method according to the present invention can generate and output information on the work execution status for each worker and work item without reducing the work efficiency of the worker. This is effective, and is useful as a work management device, a work management system, a work management method, and the like that generate and output information related to the execution status of work by a worker based on a video obtained by photographing the worker.
