  Embodiments of an evaluation apparatus, an evaluation method, and an evaluation program disclosed in the present application will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a diagram illustrating a configuration of a system according to the present embodiment. As shown in FIG. 1, the system includes an evaluation device 100 and terminal devices 30a and 30b. For example, the evaluation device 100 and the terminal devices 30a and 30b are connected to each other via the network 50. Here, the terminal devices 30 a and 30 b are shown as an example, but other terminal devices may be connected to the network 50.

  The terminal devices 30a and 30b are, for example, terminal devices that are used when an instructor instructs a farm manager or the like to satisfy examination criteria such as JGAP. For example, the terminal devices 30a and 30b are portable terminal devices that can be carried and used by instructors such as smartphones and tablet PCs. The terminal device 30a has a camera 35a, and the terminal device 30b has a camera 35b. In the following description, the terminal devices 30a and 30b are collectively referred to as the terminal device 30 unless otherwise distinguished. The cameras 35a and 35b are collectively referred to as a camera 35.

  In the present embodiment, as an example, JGAP examination standards will be described, but the invention is not limited thereto, and examination standards such as HACCP, FCP common factory management, AIB, JIB, and ISO 22000 may be used. In this embodiment, explanation is given on the assumption that the instructor uses the terminal device 30 to instruct and inspect the farm manager, but other users (examiners, etc.) examine the farm. In some cases, the terminal device 30 may be used for examination.

  The terminal device 30 classifies and displays each check item of the examination standard in a plurality of groups for each predetermined category, so that the instructor can efficiently instruct each check item of the examination standard. Here, when the instructor finds a good example at the site in connection with the examination criteria while instructing about a certain check item, the instructor operates the camera 35 of the terminal device 30 to photograph the site. To do. The terminal device 30 generates a “recorded image file” when image data is captured by the camera 35 and transmits the captured information to the evaluation device 100 described later. The recorded image file includes image data captured by the camera 35 and feature information of an operation when the instructor captures this image data.

  When the instructor repeatedly executes the above-described work on each farm, the evaluation apparatus 100 accumulates image data of a site that is a good example that satisfies the examination standard for each check item.

  Further, the instructor operates the terminal device 30 while instructing a certain check item, reads out the image data of the case satisfying the examination standard from the evaluation device 100, and presents it to the farm manager. Thereby, in addition to the guidance of the instructor, the farm manager can browse image data of a good example site that satisfies the screening criteria, and can deepen the understanding of the screening criteria.

  The evaluation device 100 is a device that holds various types of information about examination criteria and provides the terminal device 30 with various types of information about examination criteria, so that an instructor assists the farm manager with guidance. For example, when receiving an access from the terminal device 30, the evaluation device 100 provides the terminal device 30 with a tool for displaying each check item of JGAP examination criteria and a Web (World Wide Web) operation screen. In addition, the evaluation apparatus 100 collects and manages information such as information on examination results with respect to JGAP examination standards performed by the terminal device 30.

  Further, when the image data for the check item is requested, the evaluation device 100 notifies the terminal device 30 of the accumulated image data. Here, the evaluation apparatus 100 calculates the evaluation value of the image data based on the feature information included in the recorded image file. When notifying the terminal device 30 of the image data corresponding to the check item, the evaluation device 100 gives priority to the image data having a high evaluation value and notifies the terminal device 30 of the image data. Thereby, in order to understand the examination standard, it is possible to automatically evaluate whether the instructor is image data to be referred to by the farm manager.

  Next, the processing performed by the terminal device 30 and the screen example displayed by the terminal device 30 when the instructor provides guidance to the farm manager will be described.

As shown in FIG. 4, the instruction condition reception screen 72 includes a date input area 72a, a target item input area 72b, and an instruction target item input area 72c.

  The date / time input area 72a is an area for inputting the date / time when the farm to be instructed is instructed (instruction start date / time). The farm name selected on the farm selection screen 71 in FIG. 3 is set in advance as the farm name in the date / time input area 72a. The terminal device 30 may automatically input the current date and time into the date and time input area 72a, or the instructor may operate the terminal device 30 to input the date and time into the date and time input area 72a.

  The target item input area 72b is an area for inputting the type of crop to be instructed. For example, the instructor conducts a preliminary interview with the person in charge of the farm before guidance, determines the crop to be guided, operates the terminal device 30, and inputs the name of the crop in the target item input area 72b. .

  The guidance target item input area 72c is an area for inputting various conditions such as when the farm produces crops. For example, when the effort item is to be instructed, the instructor operates the terminal device 30 to check the item 1a. When growing mushrooms, the instructor operates the terminal device 30 to check the item 1b. When growing a sprout, the instructor operates the terminal device 30 to check the item 1c.

  When using agricultural chemicals, the instructor operates the terminal device 30 to check the item 1d. When considering expanding the farm, the instructor operates the terminal device 30 to check the item 1e. When shipping out of the country, the instructor operates the terminal device 30 to check the item 1f. When entrusting, the instructor operates the terminal device 30 to check the item 1g.

  When performing GGAP equivalent authentication, the instructor operates the terminal device 30 to check the item 1h. When handling genetically modified crops, the instructor operates the terminal device 30 to check the item 1i. When post-harvest is being performed, the instructor operates the terminal device 30 to check the item 1j.

  The instructor operates the terminal device 30 and presses the button 72d after finishing inputting information in the date input area 72a, the target item input area 72b, and the instruction target item input area 72c. When the terminal device 30 accepts pressing of the button 72d, the terminal device 30 transmits information input to the date input area 72a, the target item input area 72b, and the instruction target item input area 72c to the support apparatus 100. In the following description, information input to the date input area 72a, the target item input area 72b, and the guidance target item input area 72c is referred to as “input information” as appropriate.

  When the terminal device 30 transmits the input information to the evaluation device 100, the terminal device 30 receives information on the item selection screen related to the examination criteria corresponding to the input information from the support device 100. 5 and 6 are diagrams illustrating an example of the item selection screen. As shown in FIG. 5, the item selection screen 73 includes an item selection area 73a and a display area 73b. When the instructor operates the terminal device 30 to select any item in the item selection area 73a, a check item corresponding to the selected item is displayed in the display area 73b.

  For example, when the item “Farm Operation” is selected, the terminal device 30 displays a check item corresponding to the item “Farm Operation” in the display area 73b as shown in FIG.

  The instructor discusses with the farm management manager according to the content displayed in the display area 73b, operates the terminal device 30, and inputs the inspection result (check result). For example, the instructor selects “OK” or “NG” for each conformance criterion item. If “OK” or “NG” cannot be selected immediately, “hold” may be selected. Note that “conformity / nonconformity” of the conformance criteria is automatically determined based on the examination result. The terminal device 30 notifies the evaluation device 100 of information on the input inspection result. For example, in addition to the inspection result, the inspection result information includes the inspection ID, the location to be inspected, the instructor ID of the instructor who performed the inspection, the item number to be examined, and the date of the inspection. It shall be. The item number uniquely indicates the check item.

  Here, when the instructor finds a good example that serves as an example of instruction during the instruction (or examination), the instructor operates the camera 35 via the terminal device 30 to obtain a good example (site). Take a picture of. For example, when the instructor presses the record button 73c on the item selection screen 73 in FIG. 6 or the like, the terminal device 30 displays the record screen.

  FIG. 7 is a diagram illustrating an example of a recording screen. As shown in FIG. 7, the recording screen 74 has an image display area 74a, a comment input area 74b, a related item number 74c, and a shooting button 74d. The image display area 74a is an area in which image data captured by the camera 35 is displayed. The comment input area 74b is an area for inputting an instructor's comment. The related item number 74c is information associated with the check item. For example, when the related item number 74c is “1.2.1”, the corresponding check item is the item number “1.2.1”. The information of the related item number 74c may be manually input by an instructor operating the terminal device 30, or may be automatically input by the terminal device 30.

  The accepting unit 131 is a processing unit that accepts various types of information from the terminal device 30. For example, the accepting unit 131 performs a process of accepting login, a process of accepting input information, a process of accepting information on examination results, a process of accepting a recorded image file, and a process of accepting a case screen request.

  A process in which the reception unit 131 receives a login will be described. The accepting unit 131 accepts instructor ID and password information input on the login screen 70 as a login request from the terminal device 30. The reception unit 131 compares the received instructor ID and password with the instructor table 123, and receives a login request when the set of instructor ID and password exists in the instructor table 123.

  When the reception unit 131 receives the login request, the display control unit 133 outputs information indicating that the login request has been received to the display control unit 133, so that the display control unit 133 displays the information on the farm selection screen 71 and the instruction condition reception screen 72. , Transmitted to the terminal device 30 to be displayed.

  A process in which the receiving unit 131 receives input information will be described. For example, the input information indicates information input to the date input area 72a, the target item input area 72b, and the instruction target item input area 72c of the instruction condition reception screen 72.

  When receiving the input information, the receiving unit 131 compares the received input information with the condition table 122 to identify an item number corresponding to the input information. The receiving unit 131 extracts check item information corresponding to the identified item number from the JGAP reference data 121, and outputs the extracted check item information to the display control unit 133. The reception unit 131 outputs the information on the check item to the display control unit 133, so that the display control unit 133 transmits the information on the item selection screen 73 to the terminal device 30 for display.

  A process in which the reception unit 131 receives information on the inspection result will be described. When receiving the inspection result, the receiving unit 131 stores the information on the inspection result in the inspection table 124. The information on the inspection result is information input by the instructor to the display area 73b of the item selection screen 73 described with reference to FIG. Note that the inspection result information includes an inspection ID, an inspection object, an execution instructor ID, an execution date, and a result.

  A process in which the receiving unit 131 receives a recorded image file will be described. When receiving the recording image file, the receiving unit 131 registers the information of the recording image file in the shooting information table 125.

  Further, when receiving the recording image file, the reception unit 131 additionally registers the assigned image ID in the evaluation table 126. The receiving unit 131 sets an evaluation value corresponding to the additionally registered image ID as an initial value. For example, the reception unit 131 may set the initial value in any way. An initial value may be set in advance, or the reception unit 131 may use an average value, a median value, or the like of already registered evaluation values as an initial value.

  A process in which the receiving unit 131 receives a case screen request will be described. When receiving the case screen request, the receiving unit 131 outputs information indicating that the case screen request has been received to the display control unit 133. Thereby, the display control unit 133 transmits the information of the case screen file to the terminal device 30 to be displayed.

  The evaluation unit 132 is a processing unit that calculates the evaluation value for the image data based on the feature information of the operation when the image is captured. For example, the feature information corresponds to the number of steps, the number of photographing times, an enlargement flag, and a comment flag. Here, the number of times of photographing indicates the number of times that the instructor did not move so much and continuously photographed image data. The evaluation unit 132 may perform processing as follows to specify the number of times of shooting. The evaluation unit 132 sets the number of steps at the start of image data shooting at a certain location as the “reference number of steps”, and the number of image data captured up to the number of steps where the increased number of steps from the reference number of steps is less than the threshold. , The number of shots.

  The evaluation unit 132 may specify the reference number of steps in any way. For example, the evaluation unit 132 scans the number of steps in the imaging information table 125, identifies a series of records in which the difference in the number of steps before and after is “1 step” or less, and uses the smallest number of steps among the identified records as the reference number of steps. As specified. For example, in the example illustrated in FIG. 15, a series of records in which the difference in the number of steps before and after is “1 step” or less is records with image IDs “G1001 to G1004”. Among the steps included in the record of the image IDs “G1001 to G1004”, the smallest number of steps is “1000 steps”, so the reference number of steps is “1000 steps”.

  The evaluation unit 132 calculates the reference number of steps and the number of photographing times for each series of records in which the difference between the number of steps before and after is “1 step” or less. In addition, the evaluation unit 132 performs processing for classifying a series of records (image IDs) in which the difference in the number of steps before and after is “1 step” or less into the same group.

  Next, an example of processing in which the evaluation unit 132 calculates an evaluation value of image data will be described. For example, the evaluation unit 132 calculates the evaluation value of the image data based on Expression (1).

  Evaluation value = β × (α × number of photographing times + first correction value + second correction value) (1)

  In Expression (1), α is a preset correction coefficient. The number of times of photographing corresponds to the number of times of photographing of the group to which the image ID (image ID of the image data for which the evaluation value is calculated) belongs.

  The first correction value is a correction value that is “1” when the enlargement flag corresponding to the image ID is “ON” and is “0” when the enlargement flag corresponding to the image ID is “OFF”. The second correction value is a correction value that is “1” when the comment flag corresponding to the image ID is “ON” and is “0” when the comment flag corresponding to the image ID is “OFF”.

β is a value corresponding to the skill level of the instructor who photographed the image ID. The evaluation unit 132 identifies the instructor ID by comparing the image ID and the photographing information table 125, and identifies the skill level by comparing the identified instructor ID and the instructor table. For example, β when the instructor's skill level is “advanced” is β ₁ . Β when the instructor's skill level is “intermediate” is β ₂ . Β when the instructor's skill level is “beginner” is β ₃ . The magnitude relation of β is “β ₁ > β ₂ > β ₃ ”.

  The evaluation value of the image data calculated by the evaluation unit 132 has the following characteristics. The evaluation value of the image data becomes larger as the image data belongs to a group having a larger number of shootings. The evaluation value of image data increases as the instructor performs an enlargement operation. The evaluation value of the image data increases as the comment is written to the instructor. The evaluation value of the image data increases as it is photographed by a skilled instructor.

  The evaluation unit 132 repeatedly executes the above processing for each image data, associates the image ID with the evaluation value, and registers them in the evaluation table 126.

  The display control unit 133 is a processing unit that transmits various screen information to the terminal device 30 for display in cooperation with the reception unit 131 described above.

  When the display control unit 133 acquires from the reception unit 131 that the login request has been received, the display control unit 133 transmits the information on the farm selection screen 71 and the guidance condition reception screen 72 to the terminal device 30 to display the information.

  When the display control unit 133 acquires information on the check item corresponding to the input information from the reception unit 131, the display control unit 133 transmits the information on the item selection screen 73 to the terminal device 30 for display.

  When the display control unit 133 acquires information indicating that the case screen request has been received from the reception unit 131, the display control unit 133 transmits the information on the case screen file to the terminal device 30 to display the information. Hereinafter, an example of processing in which the display control unit 133 generates information of the case screen file will be described.

  The case screen request includes an item number that uniquely identifies the check item. In the following description, the item number included in the case display request is referred to as “key item number” as appropriate. The display control unit 133 compares the key item number with the item number of the photographing information table 125, and searches for an image ID and image data corresponding to the item number that hits the key item number.

  The display control unit 133 compares the searched image ID and image data set with the evaluation table 126 to identify an evaluation value corresponding to the searched image ID and image data. The display control unit 133 specifies the evaluation value in the same manner for the image ID and image data of the item number that hits the key item number.

  For example, the display control unit 133 generates the information of the case screen file by arranging the image ID and the image data in order from the largest evaluation value. FIG. 17 is a diagram illustrating an example of the data structure of the case screen file. As illustrated in FIG. 17, the case screen file associates item numbers, priorities, image IDs, evaluation values, image data, and thumbnail images.

  The item number indicates the key item number set in the case screen request. The priority indicates the priority of the image data, and the smaller the value, the higher the priority. For example, this corresponds to the order of priority when displayed in the list display area 81 of the case screen shown in FIG. 9, and the thumbnail image of the image data with the highest priority is displayed on the left side of the list display area 81. .

  The image ID is information for uniquely identifying image data. The evaluation value indicates the evaluation value of the image data. The image data is image data corresponding to the image ID. The thumbnail image is a thumbnail image of image data. For example, the display control unit 133 reduces the original image data to generate a thumbnail image and registers it in the case screen file. In the example illustrated in FIG. 17, the case in which the evaluation value is included in the case screen file has been described. However, if the priority order of each image data can be specified, the evaluation value may not be included in the case screen file.

  The display control unit 133 sorts the image data in descending order of the evaluation value when the number of image data of the item number that hits the key item number is equal to or greater than the threshold, and the top N image data The information about is stored in the case screen file. N is a natural number and is set in advance. On the other hand, the display control unit 133 sorts each image data in descending order of evaluation value and stores it in the case screen file when the number of image data of the item number hitting the key item number is less than the threshold value. .

  Next, an example of a processing procedure of the terminal device 30 according to the present embodiment will be described. FIG. 18 is a flowchart illustrating the processing procedure of the terminal device according to the present embodiment. As illustrated in FIG. 18, when the terminal device 30 receives a shooting instruction from an instructor (step S101), the terminal device 30 captures image data (step S102).

  The terminal device 30 acquires the number of steps (step S103) and updates the number of steps (step S104). The terminal device 30 receives various operations (step S105). For example, various operations correspond to an enlargement operation and a comment writing.

  The terminal device 30 stores each information in the recording image file (step S106). For example, each piece of information stored in the recording image file corresponds to a terminal ID, an instructor ID, an image ID, a comment, an item number, image data, a shooting location, a step count, an enlargement flag, and a comment flag.

  If the terminal device 30 has not finished photographing (No at Step S107), the terminal device 30 proceeds to Step S101. If the terminal device 30 has finished photographing (step S107, Yes), the terminal device 30 transmits the recorded image file to the evaluation device 100 (step S108).

  Next, an example of a processing procedure of the evaluation apparatus 100 according to the present embodiment will be described. FIG. 19 is a flowchart illustrating the processing procedure of the evaluation apparatus according to the present embodiment. As illustrated in FIG. 19, the receiving unit 131 of the evaluation device 100 receives a recorded image file from the terminal device 30 (step S201).

  The receiving unit 131 registers the recorded image file in the shooting information table 125 (step S202). The evaluation unit 132 of the evaluation apparatus 100 calculates an evaluation value for each image ID based on the feature information of each image data in the shooting information table 125 (step S203). The evaluation unit 132 updates the evaluation table 126 (Step S204).

  Next, the effect of the evaluation apparatus 100 according to the present embodiment will be described. The evaluation device 100 calculates an evaluation value of each image data based on the feature information of the operation of the instructor who takes the image data. This makes it possible to evaluate whether or not the content is to be referred to. By evaluating by this method, it is possible for an instructor or the like who has captured the image data to eliminate the trouble of evaluating the image data by referring to the accumulated image data. In the present embodiment, image data is used as an example of content. However, the present invention is not limited to this, and moving image data may be used.

  When notifying the terminal device 30 of the image data corresponding to the check item, the evaluation device 100 gives priority to the image data having a high evaluation value and notifies the terminal device 30 of the image data. Thereby, in order to understand the examination standard, it is possible to automatically evaluate whether the instructor is image data to be referred to by the farm manager.

  The evaluation apparatus 100 gives a higher evaluation value for a group of image data having a large number of times of photographing while the number of steps taken by the instructor is not so much (in the same place) as compared to a group of image data having a small number of times of photographing . When the number of times of photographing is the same at the same place, it can be said that the image data includes important points related to the examination criteria, and therefore the evaluation value of the image data can be set appropriately.

  The evaluation apparatus 100 increases the value added to the evaluation value for the image data on which the enlargement operation has been performed, compared to the image data on which the enlargement operation has not been performed. Since it can be said that the image data subjected to the enlargement operation includes important points related to the examination standard, the evaluation value of the image data can be appropriately set.

  The evaluation apparatus 100 increases the value added to the evaluation value for the image data in which the comment is written, compared to the image data in which no comment is written. Since the image data in which the comment is written is often a good example in examination criteria, the evaluation of the image data can be set appropriately.

  The evaluation device 100 performs a process of correcting the evaluation value according to whether or not the instructor who has captured the image data is an expert. Thereby, the evaluation value of the image data photographed by the expert can be increased, and the evaluation value becomes more appropriate.

  Note that the evaluation apparatus 100 may set an evaluation value for the image data by performing other processing. For example, the evaluation unit 132 of the evaluation apparatus 100 may give a larger evaluation value to the image data when the instructor does not change the shooting position and is shooting many times while changing the shooting angle. When this processing is performed, the terminal device 30 acquires information on the shooting position using a GPS (Global Positioning System) function every time image data is shot, and stores the information on the shooting position in the recorded image file. Including, it shall transmit to the evaluation apparatus 100. The evaluation apparatus 100 registers the information of the recording image file including the shooting position information in the shooting information table 125.

  The evaluation apparatus 100 refers to the shooting information table 125 to identify a set of records whose change in shooting position is less than the threshold, and for the specified set of records, the number of steps corresponding to the first record and the last When the difference from the number of steps corresponding to a record is greater than or equal to a threshold, a larger evaluation value is given to the evaluation value of image data belonging to the record. That is, the evaluation unit 132 determines that the image is taken many times while changing the shooting angle when the shooting position is not changed and the number of steps is increased by a threshold value or more. For example, the evaluation unit 133 sets the third correction to the value calculated by the expression (1) when the image data satisfies the above-described condition (the condition that the image is captured many times while changing the imaging angle). Add a value. It is assumed that the third correction value is set in advance.

  Next, an example of a hardware configuration of a computer that realizes the same function as the evaluation apparatus 100 shown in the above embodiment will be described. FIG. 20 is a diagram illustrating an example of a hardware configuration of a computer that implements the same function as the evaluation apparatus.

  As illustrated in FIG. 20, the computer 200 includes a CPU 201 that executes various arithmetic processes, an input device 202 that receives input of data from a user, and a display 203. The computer 200 also includes a reading device 204 that reads a program or the like from a storage medium, and an interface device 205 that exchanges data with a recording device or the like via a wired or wireless network. The computer 200 also includes a RAM 206 that temporarily stores various information and a hard disk device 207. The devices 201 to 207 are connected to the bus 208.

  The hard disk device 207 has a reception program 207a, an evaluation program 207b, and a display control program 207c. The CPU 201 reads each program 207 a to 207 c and develops it in the RAM 206.

  The reception program 207a functions as a reception process 206a. The evaluation program 207b functions as an evaluation process 206b. The display control program 207c functions as a display control process 206c.

  The process of the reception process 206a corresponds to the process of the reception unit 131. The process of the evaluation process 206b corresponds to the process of the evaluation unit 132. The processing of the display control process 206c corresponds to the processing of the display control unit 133.

  Note that the programs 207a to 207c are not necessarily stored in the hard disk device 507 from the beginning. For example, each program is stored in a “portable physical medium” such as a flexible disk (FD), a CD-ROM, a DVD, a magneto-optical disk, and an IC card inserted into the computer 200. Then, the computer 200 may read and execute each of the programs 207a to 207c.
