  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1. Basic Configuration of System First, FIG. 1 shows a system configuration diagram of a construction site management system in the present embodiment. The system includes a digital camera 10, a mail server (mail server computer) 14, an ASP server (ASP server computer) 16, and management terminals (terminal devices) 18 and 20. The digital camera 10, the mail server 14, the ASP server 16, and the management terminals 18 and 20 are connected to the Internet 12 by radio or wire.

  The digital camera 10 as an imaging means is operated by a worker at a construction site. The operator operates the digital camera 10 to take a site photograph of the construction site. The digital camera 10 is connected to the Internet 12 by radio. The worker transmits image data of a field photograph taken with the digital camera 10 to the mail server 14 via the Internet 12. That is, the worker transmits the image data of the photographed site photograph to the mail server 14 in the e-mail format. The destination for sending the image data of the field photograph from the digital camera 10 in the e-mail format, that is, the e-mail address is stored in the memory in the digital camera 10 in advance, and the operator operates the send button of the digital camera 10. Just send an e-mail to the desired destination. The image data of the on-site photo is transmitted to the mail server 14 as an attached file of the e-mail. When the image data of the field photograph is in JPEG format, the JPEG format is converted into text data using an encoder such as Base64.

  The mail server 14 receives the e-mail transmitted from the digital camera 10 and extracts the image data of the field photograph attached to the e-mail. The mail server 14 transmits the extracted image data of the site photo to the ASP server 16. The mail server 14 transmits the image data of the field photograph to the ASP server 16 via the Internet 12, but can also be transmitted to the ASP server 16 via a dedicated line instead of the Internet 12. The dedicated line is either a public line or a non-public line. When a plurality of site photos are taken by the digital camera 10 and image data of the plurality of site photos are transmitted one by one to the mail server 14 in an email format, the mail server 14 receives a plurality of emails. In this case, the mail server 14 sorts the image data of the field photo based on the data in the subject (subject) of each electronic mail and transmits it to the ASP server 16. The data in the subject is a project number and a folder project number. In the digital camera 10, a folder is formed for each transmission destination, and the image data of the photographed on-site photograph is stored together in each folder in the digital camera 10. When transmitting image data of a plurality of different site photographs to the same transmission destination, the plurality of image data cannot be distinguished from each other in a single folder. Therefore, the digital camera 10 manages the plurality of image data with the project number assigned to each folder. The project number is automatically inserted into the subject (subject) of the e-mail by the processor of the digital camera 10. The mail server 14 sorts the image data of the field photograph using the project number in the subject and transmits it to the ASP server 16.

  The ASP server 16 stores the image data of the field photo for each project number transmitted from the mail server 14 in a database, and edits or processes the image data into a predetermined format using the image data of the field photo stored for each project number. To generate file data. The ASP server 16 also specifies a management terminal that manages the digital camera 10 based on the ID of the digital camera 10 included in the subject of the e-mail when the image data of the field photograph is received from the mail server 14. The reception notification is transmitted to the identified management terminal via the Internet 12. For example, it is assumed that the management company A is a user of the management terminal 18 and manages a worker who operates the digital camera 10. The ASP server 16 manages the digital camera 10 based on the ID of the digital camera 10 as the management company A, and the management company A is a user of the management terminal 18. Therefore, the ASP server 16 is managed as a management terminal that manages the digital camera 10. The terminal 18 is specified. If there is another digital camera in addition to the digital camera 10 and the management company B is a user of the management terminal 20 and manages a worker who operates the other digital camera, the ASP server 16 Since the management company B manages the other digital camera based on the ID of the other digital camera, and the management company B is a user of the management terminal 20, the management terminal that manages the other digital camera. The management terminal 20 is specified as follows.

  When an image data file of a site photograph is necessary, the administrator of the management company who is a user accesses the ASP server 16 using the management terminal 18 or the management terminal 20, and is edited or processed by the ASP server 16. The file data is acquired and displayed on the display device of the management terminal 18 or the management terminal 20. The administrator visually confirms the file data displayed on the display device of the management terminal 18 or the management terminal 20, thereby confirming the image data of the site photograph taken by the digital camera 10 or another digital camera at the construction site, You can check the construction status.

2. Configuration of Digital Camera FIG. 2 is a block diagram showing the configuration of the digital camera 10. The digital camera 10 includes a sensor (image sensor) 10a such as CMOS or CCD, a DSP (digital signal processor) 10b, a CPU 10c, a memory interface (I / F) 10d, a JPEG codec 10e, a memory 10f, and a communication interface (I / F). With 10 g. Although not shown in the figure because it is publicly known, the digital camera 10 also includes an optical system such as a focus lens, a zoom lens, a shutter, and a diaphragm, and forms an object image on the sensor 10a by the optical system.

  The sensor 10a converts an image of a construction site as a subject into an electrical signal. The electrical signal is converted into a digital image signal and supplied to the DSP 10b.

  The DSP 10b performs various processing such as gain correction (white balance sensitivity setting), gamma correction, synchronization processing, RGB-YC conversion processing, noise reduction processing, and contour correction on the digital image data.

  The JPEG codec 10e converts and compresses the digital image data processed by the DSP 10b into the JPEG format, and stores it in the memory 10f as image data of a field photograph. The memory 10f is, for example, a flash memory.

  The CPU 10c collectively manages in the folder created for each transmission destination when the image data of the field photograph is stored in the memory 10f. For example, when there are two transmission destinations, folders having respective transmission destination numbers are created. The CPU 10c assigns a project number to each destination folder in order from the initial value. The shooting date and time is also stored in the memory 10f at the same time. Further, basic data on the image data of the on-site photograph, for example, the situation at the time of photographing and the data of the photographing part are also stored in the memory 10f. When transmitting the image data of the site photo to the mail server 14, the CPU 10c converts the image data of the site photo stored in the transmission destination folder into text data as an attached file of the e-mail and transmits it. Further, data such as a project number is read from the memory 10f and automatically inserted into the subject (subject) of the e-mail. When the CPU 10c transmits the image data of all the site photos stored in the transmission destination folder to the mail server 14, the CPU 10c deletes the transmitted image data from the image data stored in the memory 10f. Increment the project number of the destination folder by 1 to prepare for the next transmission. A unique file name incremented from the initial value is assigned to each of the image data of the plurality of field photographs.

  The project number of the destination folder is sequentially incremented from 1, but the upper limit can be fixed to 10, for example. When the project number reaches 10, the project number returns to 1 again. In addition to the project number, the project name may be entered. The project name is specifically the name of the construction site, the name of the building to be constructed, etc., and is at least character information for identifying the construction site. Therefore, the project number and the project name are attached to the transmission destination folder as a set. The operator of the digital camera 10 can input the project name. Alternatively, the management company that manages the digital camera 10 can input the digital camera 10 before distributing it to the current worker. Alternatively, by storing a program for automatically inputting a project name in the USB memory and inserting the USB memory into the digital camera 10, the program starts execution, and the project name can be automatically input. Alternatively, project name data may be transmitted from the ASP server 16 to the digital camera 10 via the Internet 12.

  The technical reason for adding the project name in addition to the project number is as follows. That is, there are not a few cases where workers on a construction site move around the construction site according to time. For example, a specific operation is performed at one construction site in the morning, and a specific operation is performed at another construction site in the afternoon. In this case, since the construction site is different between morning and afternoon, the image data of the site photograph taken by the worker must be distinguished from each other. Although it is possible to distinguish each other by making the project number of the destination folder different in the morning and afternoon, it is difficult to recognize that the construction site is different only by the project number. This is because it may be necessary to change the project number even when taking site photographs of slightly different parts even at the same construction site. Therefore, by adding the name of the construction site as a project name in addition to the project number, it becomes possible to easily grasp the fact that the construction site has changed.

  The subject of the e-mail transmitted from the digital camera 10 to the mail server 14 includes an ID that is a unique identification number uniquely assigned to the digital camera 10, a transmission destination number, a folder project number, a folder project name, a file number, Includes shooting date / time, field number, and total number of files in the folder. For example, the format of an electronic mail subject is A-B-C-D-E-F-G. Here, A is the ID of the digital camera 10, B is the destination number, C is the folder project number and folder project name, D is the file number, E is the shooting date, F is the folder number, and G is the total number of files in the folder. Show.

3. Configuration of ASP Server FIG. 3 is a block diagram showing the configuration of the ASP (Application Service Provider) server 16. The ASP server 16 includes a communication interface (I / F) 16a, a CPU 16b, a memory 16c such as a ROM and a RAM, a user attribute database (DB) 16d for storing user attributes, and an image database (DB) for storing image data of field photographs. 16e includes a file database (DB) 16f that stores file data obtained by editing and processing image data into a predetermined file format.

  The user attribute database 16d includes basic information of a management company (or a person in charge of the management company) as a user, specifically, a name, an address, an IP address of the management terminal 18 (or the management terminal 20), and a digital managed by the management company. The ID of the camera 10 is associated and stored as a table. For example, as the digital camera 10, there are five digital cameras, a digital camera A, a digital camera B, a digital camera C, a digital camera D, and a digital camera E, and these are all managed by an administrator. A person's name, the management terminal 18, and the IDs of the digital cameras A to E are associated with each other and stored as a table. By referring to this table, it is possible to identify which digital camera is managed by the administrator. The user attribute database 16d further stores a user ID and password for each management company that is a user.

  The CPU 16b uses the table stored in the user attribute database 16d to determine from which digital camera the image data of the field photograph is transmitted and to which management terminal the reception completion notification is transmitted. Further, in response to a request from the management terminal 18 (or the management terminal 20), the image data of the field photograph is read from the image database 16e or the file database 16f and transmitted to the management terminal 18 (or the management terminal 20). Various processes of the ASP server 16 are basically executed by the CPU 16b.

4). Processing Contents of Mail Server and ASP Server FIG. 4 shows a processing flowchart of the mail server 14 and the ASP server 16. This is processing of the CPU of the mail server 14 and the CPU 16b of the ASP server 16. First, the mail server 14 sequentially receives e-mails transmitted from the digital camera 10 (S101). The e-mail is accompanied by image data of a field photograph.

  Next, the mail server 14 sorts the image data of the field photograph for each project number included in the received e-mail subject and transmits it to the ASP server 16 (S102). The ASP server 16 receives the image data of the field photo from the mail server 14, sorts it by project number and project name, and stores them in the image database 16e.

  Next, the ASP server 16 identifies or identifies the management terminal of the management company that manages the digital camera 10 corresponding to the ID from the ID in the subject of the email using the table stored in the user attribute database 16d. (S103). In the table stored in the user attribute database 16d, an ID is assigned to each of the plurality of digital cameras, and a management terminal is assigned to each ID of the plurality of digital cameras. Is transmitted, the ASP server 16 can specify the management terminal from the ID included in the subject of the e-mail.

  Next, the ASP server 16 notifies the identified or specified management terminal of the completion of the reception of the e-mail (S104). The reception completion notification includes data of the digital camera ID, the number of received images, and the shooting date and time. These are all data included in the subject of the received electronic mail. Further, the ASP server 16 reads out the image data of the field photo stored for each project number from the database from the image database 16e, edits it into a predetermined file format, and stores it in the file database 16f (S105). In the figure, the image data is edited into a predetermined format after notifying the management terminal of completion of reception. However, it is also possible to notify the management terminal of completion of reception after editing the image data into a predetermined format.

  The file format is determined based on the user attributes stored in the user attribute database 16d. However, when the data of the received e-mail contains data related to the file format, it can be edited based on the format data.

  The management terminal that has received the reception completion notification requests the ASP server 16 for the image data of the field photograph. For example, when the management terminal identified by the ASP server 16 is the management terminal 18 and the ASP server 16 transmits a reception completion notification to the management terminal 18, the person in charge of the management company who is the user of the management terminal 18 uses the management terminal 18. To confirm the reception completion notification. Then, after confirming the reception completion notification, the person in charge of the management company requests the ASP server 16 to transmit image data of the field photograph from the management terminal 18 via the Internet 12. When receiving a request for image data transmission from the management terminal, the ASP server 16 transmits the edited image data stored in the file database 16f to the management terminal (S106).

  This will be described in more detail as follows. That is, when the user of the management terminal 18 receives a reception completion notification from the ASP server 16, the user accesses the ASP server 16 using the management terminal 18. When there is an access request from the management terminal 18, the ASP server 16 requests input of a user name and a password. The user of the management terminal 18 inputs and transmits a user name and password to the ASP server 16 in response to this request. When the ASP server 16 receives the user name and password from the management terminal 18, the ASP server 16 compares the user name and password stored in the user attribute database 16d with the received user name and password to confirm whether or not the user is the correct user. Yes (user authentication). When the user authentication is completed, the user of the management terminal 18 proceeds to a process for requesting a necessary file. File types include display for each digital camera, photo list, slide show, and matrix. These will be described individually below.

5. Photo List FIG. 5 shows a list screen of digital cameras managed by a management company that is a user of the management terminal 18 (the processing of the management terminal 20 is the same). When the user authentication is completed, the ASP server 16 displays a list of digital cameras managed by the management company that is the user of the management terminal 18 on the screen 100 of the management terminal 18. In the figure, a display 101 such as camera A, camera B, camera C, etc. at the upper right of the screen 100 is a list of digital cameras managed by the management company. That is, the ASP server 16 specifies all digital cameras managed by the administrator by accessing the user attribute database 16d, and transmits information on the specified digital cameras, for example, the ID of the digital camera, to the management terminal 18. The specified digital camera information may be the name of the construction company to which the operator operating the digital camera belongs, in addition to the ID of the digital camera. In this screen 100, when there are four digital cameras, digital camera A, digital camera B, digital camera C, digital camera D, and digital camera E, as the digital camera 10 managed by the management company that is the user of the management terminal 18. Is assumed. In the figure, the digital camera A is abbreviated as “camera A” or the like. “Camera A” actually means the ID of the digital camera A as described above. For example, when the ID of the digital camera A is “00001”, this ID is displayed on the screen 100. . The digital cameras A to E may be operated by different workers of the same construction contractor, or may be operated by different workers of different construction contractors. The digital cameras A to E are operated by workers at different construction sites, and take different site photographs at different timings. The screen 100 displays a list of image data of field photographs transmitted from all the digital cameras A to E managed by the management company. In the figure, the image data group 104 shows a list of image data of field photographs. The manager of the management company can easily and collectively grasp the progress status of all the construction sites by viewing this image data list. Further, when the manager of the management company who is the user of the management terminal 18 wants to check the on-site photograph taken with the digital camera A, the digital camera A on the screen 100 is designated and the ASP server 16 is designated. Requests transmission of image data. As an example, the screen 100 shown in FIG. 5 is described in the HTML format, and the administrator clicks the displayed “camera A” and is photographed by the digital camera A with respect to the ASP 16. Requests transmission of image data.

  FIG. 6 shows an example of a screen that is transmitted from the ASP server 16 and displayed on the screen 100 of the management terminal 18 when the administrator designates “camera A” in FIG. A list of all project numbers and project names in the folder of the digital camera A is displayed. For example, the folder of the digital camera A has project numbers 1 to 4, and the project name (abbreviated as aaa, bbb, ccc, ddd in the figure) is displayed together with each project number. As described above, the project name represents the name of the construction site or the name of the building. The administrator designates a desired project number and project name from these. The screen shown in FIG. 6 can be an HTML screen similar to the screen shown in FIG. The administrator requests the ASP server 16 to transmit image data by clicking on any project number or project name.

  FIG. 7 shows an example of a screen that is transmitted from the ASP server 16 and displayed on the screen 100 of the management terminal 18 when the administrator designates, for example, the project number 1 and the project name aaa in FIG. A list of all images included in folder project number 1 and project name aaa of digital camera A is displayed. In the figure, image data of nine field photographs indicated by P001 to P009 are displayed. The manager can easily grasp the progress status of the construction site by viewing this screen. Each image data can be displayed together with the shooting date and project name. Since the project name includes text information indicating the construction site, the administrator can easily see where the image data was taken and when it was taken by viewing the screen in FIG. Can be confirmed.

6). Slideshow In FIG. 5, a “slideshow” link 102 is displayed at the lower right of the screen 100. When the administrator clicks on the link 102 of the slide show, the ASP server 16 selects 50 pieces of image data having a new shooting date and time among the image data of the field photographs taken by the digital cameras A to E managed by the administrator. Is automatically selected and displayed on the screen 100 of the management terminal 18 at a predetermined interval (for example, 20 seconds) (slide show). More specifically, the processor 16b of the ASP server 16 accesses the image database 16e in response to a request from the management terminal 18, and the shooting date / time of the image data of the field photographs taken by the digital camera A to digital camera E is 50 new image data are extracted. Then, the extracted image data is sorted in order of photographing date and time, and sequentially transmitted to the management terminal 18 at a predetermined interval. There are two methods for sorting in order of shooting date and time. There are a method of sorting from the oldest shooting date and time and a method of sorting from the newest shooting date.

  FIG. 8 shows an example of a slide show. The 50 image data with the latest shooting date and time are displayed in order from the oldest shooting date and time. First, on-site photo image data P001 is displayed on the screen 100, along with the digital camera name, the shooting date and time, and the reception date and time, which are basic information of the image data P001. The digital camera name is an ID of the digital camera. When a predetermined time, for example, 20 seconds elapses after displaying the image data P001, the on-site photo image data P002 is displayed, along with the digital camera name, the shooting date / time, and the reception date / time, which are basic information of the image data. Is displayed. When a predetermined time, for example, 20 seconds elapses after the image data P002 is displayed, the image data P003 of the on-site photograph is displayed, and the digital camera name, shooting date / time, and reception date / time, which are basic information of the image data, are displayed together with this. Is displayed. Thereafter, the image data is sequentially displayed on the screen 100 in the same manner.

  The manager can confirm the progress status of the construction site by visually recognizing the image data of the site photos automatically displayed on the management terminal 18 sequentially. In the present embodiment, the latest 50 images are sequentially displayed among the image data of the field photographs taken by the plurality of digital cameras A to E managed by the administrator. It is also possible to sequentially display the latest 50 pictures among the image data of the on-site photographs taken by a specific digital camera in E, for example, the digital camera A. In the present embodiment, the latest 50 images are displayed sequentially from the oldest shooting date and time, but can be displayed sequentially from the newest shooting date and time.

7). Matrix In FIG. 5, a “matrix” link 103 is displayed at the lower left of the screen 100. When the administrator clicks on the matrix link 103, the ASP server 16 collectively displays the image data of the field photographs taken by the digital cameras A to E managed by the administrator in a matrix format. More specifically, the CPU 16b of the ASP server 16 reads image data of field photographs transmitted from the digital cameras A to E managed by the administrator from the image database 16e, performs the shooting date and time, and lists the types of digital cameras. A two-dimensional matrix file is created by plotting the presence or absence of image data on the two-dimensional matrix. The created two-dimensional matrix file is stored in the file database 16f. In response to a request from the management terminal 18, the CPU 16 b reads a two-dimensional matrix file from the file database 16 f and transmits it to the management terminal 18.

  FIG. 9 shows an example of matrix display. The matrix column is the shooting date and time, and is divided into yesterday, yesterday, and today, and is further divided into time zones of 9 o'clock to 12 o'clock, 12 o'clock to 15 o'clock, and 15 o'clock to 18 o'clock on each day. The rows of the matrix are digital cameras, and are divided into digital cameras A to E. In the matrix, a circle is displayed when there is image data of a field photograph. For example, in the digital camera A, when there is image data of an on-site photograph whose shooting date is yesterday at 10:00, a circle is displayed. On the other hand, in the digital camera A, when there is no image data of a field photograph whose shooting date is yesterday from 12:00 to 15:00, no circle is displayed. 9 is displayed on, for example, an HTML screen. When the administrator clicks a circle, the ASP 16 is requested to transmit image data of the corresponding shooting date and time of the corresponding digital camera, and the management terminal 18 Image data is displayed on the screen 100.

  By viewing the matrix in FIG. 9, the administrator can collectively check the shooting status of the digital cameras A to E managed by the administrator. The manager can also check whether the operator who should operate the digital camera exists at the construction site by visually recognizing this matrix. For example, in the digital camera A, when a site photograph should have been taken yesterday from 12:00 to 15:00, in this matrix, there is no image data of the site photograph in the corresponding time zone. It can be confirmed that the worker did not exist. That is, the presence / absence check of the worker on site can be easily performed by this matrix.

  In addition, by using this matrix, the progress status of each construction site can be easily understood, so the progress status is steady at one construction site, but the construction is not progressing as planned at another construction site. If it is understood, it is possible to easily assign workers from a construction site where the progress is smooth to a construction site that is not progressing as planned.
