EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing.

1. Basic Configuration of the System

First, the system block diagram of the construction site management system in this embodiment is shown in FIG. The system includes a digital camera 10, a mail server (mail server computer) 14, an ASP server (ASP server computer) 16, a management terminal (terminal device) 18, and 20. FIG. The digital camera 10, the mail server 14, the ASP server 16, the management terminals 18, and 20 are connected to the Internet 12 by wireless or wired, respectively.

The digital camera 10 as the photographing means is operated by the worker at the construction site. The operator operates the digital camera 10 to take a picture of the site of the construction site. The digital camera 10 is connected to the Internet 12 by wireless. The worker transmits the image data of the field picture photographed by the digital camera 10 to the mail server 14 via the Internet 12. That is, the worker transmits the image data of the photographed field picture to the mail server 14 in an e-mail format. The destination when transmitting the image data of the field picture from the digital camera 10 in an e-mail format, that is, the mail address is stored in the memory in the digital camera 10 in advance, and the operator presses the send button of the digital camera 10. You can send an e-mail to the desired destination just by operating it. The image data of the field picture is transmitted to the mail server 14 as an attachment of an e-mail. When the image data of the scene photograph is a JPEG format, the JPEG format is converted into text data using an encoder such as a base 64.

The mail server 14 receives the e-mail sent from the digital camera 10, and extracts the image data of the field picture attached to the e-mail. The mail server 14 transmits the extracted image data of the scene photograph to the ASP server 16. Although the mail server 14 transmits the image data of the field photograph to the ASP server 16 via the Internet 12, it can also transmit to the ASP server 16 via a dedicated line instead of the Internet 12. The leased line is either a public line or a non-public line. When the plurality of field pictures are taken by the digital camera 10, and the image data of the plurality of field pictures is transmitted to the mail server 14 one by one in the form of an e-mail, the mail server 14 receives the plurality of e-mails. Receive In this case, the mail server 14 classifies and transmits the image data of the scene photograph to the ASP server 16 based on the data in the subject (name) of each e-mail. The data in the subject is the project number and the folder project number. In the digital camera 10, a folder is formed for each transmission destination, and the image data of the photographed field pictures is collectively stored in each folder in the digital camera 10. When image data of a plurality of field pictures is transmitted to the same transmission destination, these plurality of image data cannot be distinguished from each other in a single folder. Therefore, the digital camera 10 manages these plurality of image data by 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 classifies and transmits the image data of the field picture to the ASP server 16 using the project number in the subject.

The ASP server 16 stores in the database image data of the field pictures for each project number sent from the mail server 14, and edits them in a predetermined format using the image data of the field pictures stored for each project number. Process and generate file data. The ASP server 16 also 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 picture is received from the mail server 14. A management terminal is specified, and a reception notification is transmitted to the specific 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 an operator who operates the digital camera 10. The ASP server 16 manages the digital camera 10 based on the ID of the digital camera 10, and since the management company A is a user of the management terminal 18, the digital camera 10 The management terminal 18 is specified as a management terminal for managing the operation. In addition, if there is a digital camera other than the digital camera 10, and the management company B is a user of the management terminal 20 and manages the operator who operates the other digital camera, the ASP server 16 The management company B manages the other digital cameras based on the IDs of the other digital cameras, and since the management company B is a user of the management terminal 20, the management terminal manages the other digital cameras. The management terminal 20 is specified.

When a manager of a management company, which is a user, needs an image data file of a field picture, the manager terminal 18 or the manager terminal 20 is used to access the ASP server 16, and can be edited or edited by the ASP server 16. The processed file data is acquired and displayed on the display device of the management terminal 18 or the management terminal 20. The manager checks the image data of the field picture taken by the digital camera 10 or another digital camera at the construction site by visually confirming the file data displayed on the display device of the management terminal 18 or the management terminal 20. We can confirm the situation of construction.

2. Composition of Digital Camera

2 shows a block diagram of the digital camera 10. The digital camera 10 includes a sensor (image sensor) 10a such as a CMOS or CCD, a digital signal practor (10b), a CPU (10c), a memory interface (I / F) 10d, A JPEG codec 10e, a memory 10f, and a communication interface I / F 10g are provided. In addition, although it is a well-known matter and is not shown in figure, the digital camera 10 also has optical systems, such as a focus lens, a zoom lens, a shutter, and an aperture, and forms the subject image on the sensor 10a by an optical system.

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

The DSP 10b executes various processes 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 a 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.

When the CPU 10c stores the image data of the scene photograph in the memory 10f, the CPU 10c collectively manages the folder created for each transmission destination. For example, if there are two transmission destinations, a folder with each transmission destination number is created. The CPU 10c sequentially assigns a project number to each destination folder from the initial value. The shooting date and time are also stored in the memory 10f at the same time. In addition, the basic data on the image data of the field photograph, for example, the situation at the time of shooting and the data of the photographed part are also stored in the memory 10f. When the image data of the field photo is transmitted to the mail server 14, the CPU 10c converts the image data of the field photo stored in the destination folder into text data as an e-mail attachment and transmits it. In addition, data such as a project number is read from the memory 10f and automatically inserted into the subject (subject name) of the e-mail. If the CPU 10c transmits the image data of all the field pictures stored in the destination folder to the mail server 14, the CPU 10c deletes the transmitted image data among the image data stored in the memory 10f, and again the transmission destination. Increment the project number of the folder by 1 to prepare for the next transmission. Further, each of the image data of the plurality of field pictures is given a unique file name incremented from the initial value.

The project number of the destination folder is incremented sequentially from 1, but the upper limit can be fixed to 10, for example. If the project number goes to 10, the project number goes back to 1. In addition to the project number, a project name may be entered. Specifically, the project name is a name of a construction site, a name of a building to be constructed, and the like, and is at least text information specifying the construction site. Therefore, the project number and the project name are given to the destination folder as a set. The project name can be input by the operator of the digital camera 10. Alternatively, a management company managing the digital camera 10 may input the digital camera 10 before distributing it to the current worker. Alternatively, by storing a program for automatically inputting a project name into the USB memory and inserting the USB memory into the digital camera 10, the program can start execution and automatically input the project name. Alternatively, the project name data may be transmitted from the ASP server 16 to the digital camera 10 via the Internet 12.

In addition to the project number, the technical reason for adding a project name is as follows. That is, the worker of the construction site is not often moved to the construction site over time. For example, certain work is performed at a construction site in the morning, and specific work is performed at another construction site in the afternoon. In this case, since the construction site is different in the morning and afternoon, the image data of the field pictures photographed by the worker must be distinguished from each other. It is possible to distinguish the project numbers in the destination folder by different numbers in the morning and afternoon, but it is difficult to recognize that the construction site is different only by the project numbers. This is because even in the same construction site, it may be necessary to change the project number even when shooting field pictures of somewhat different parts. Therefore, it is possible to easily grasp the fact that the construction site has changed by adding the construction site name and the like as the project name in addition to the project number.

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

3. ASP  Server configuration

3 shows a block diagram 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 or a RAM, a user attribute database (DB) 16d for storing user attributes, and a field picture. And an image database (DB) 16e for storing the image data, and a file database (DB) 16f for storing the file data obtained by editing and processing the image data in 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) that is a user, specifically, name, address, IP address of the management terminal 18 (or management terminal 20), and the management company. The ID of the digital camera 10 to manage is matched and stored as a table. For example, as the digital camera 10, there are five digital cameras of digital camera A, digital camera B, digital camera C, digital camera D, and digital camera E, all of which are managed by an administrator. The names and the management terminals 18 and IDs of the digital cameras A to E are correspondingly stored as tables. By referring to this table, it is possible to specify which digital cameras the manager manages. 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 picture is transmitted and to which management terminal to send a reception completion notification. Also, in response to a request from the management terminal 18 (or the management terminal 20), image data of the field picture is read out from the image database 16e or the file database 16f, and the management terminal 18 (or management). To the terminal 20). Various processes of the ASP server 16 are basically executed by the CPU 16b.

4. Mail server and ASP  Processing contents of the server

4 shows a processing flowchart of the mail server 14 and the ASP server 16. This is the processing of the CPU of the mail server 14 and the CPU 16b of the ASP server 6. First, the mail server 14 sequentially receives the e-mail sent from the digital camera 10 (S101). In the e-mail, image data of a field photograph is attached.

Subsequently, the mail server 14 classifies the image data of the field picture 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 picture from the mail server 14, and stores the image data in the image database 16e separately for each project number and project name.

Next, the ASP server 16 uses a table stored in the user attribute database 16d as a management terminal of the management company managing the digital camera 10 corresponding to the ID from the ID in the subject of the e-mail. Identification or identification (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, so that e-mail is transmitted from, for example, the plurality of digital cameras. Even if it is, the ASP server 16 can specify the management terminal from the ID included in the subject of the e-mail.

Subsequently, the ASP server 16 notifies completion of reception of the e-mail to the identification or specific management terminal (S104). The reception completion notification includes the data of the ID of the digital camera, the number of images received, and the photographing date and time. These are all data contained in the subject of the received e-mail. In addition, the ASP server 16 reads out the image data of the field picture 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 in a predetermined format after the management terminal is notified of the reception completion. However, after the image data has been edited in the predetermined format, the management terminal can be notified of the reception completion.

The file format is determined based on the user attribute stored in the user attribute database 16d. However, if the body of the received e-mail contains data relating 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 image data of the field picture. For example, when the management terminal 18 is a specific management terminal for the ASP server 16, and the ASP server 16 sends a reception completion notification to the management terminal 18, the management company that is a user of the management terminal 18 The person in charge checks the reception completion notification using the management terminal 18. After confirming this reception completion notification, the person in charge of the management company requests the ASP server 16 to transmit image data of the field picture from the management terminal 18 via the Internet 12. Upon receiving the 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).

More detailed description is as follows. That is, when the user of the management terminal 18 receives the reception completion notification from the ASP server 16, the user of the management terminal 18 uses the management terminal 18 to access the ASP server 16. The ASP server 16 requests the input of a user name and a password when there is an access request from the management terminal 18. The user of the management terminal 18 inputs and transmits a user name and a password to the ASP server 16 in accordance with this request. When the ASP server 16 receives the user name and password from the management terminal 18, it checks whether the user name and password stored in the user attribute database 16d and the received user name and password are valid users. Check (User Authentication). After the user authentication is completed, the user of the management terminal 18 then proceeds to processing for requesting the necessary file. Examples of the file types include display, picture list, slide show, and matrix for each digital camera. Hereafter, these are demonstrated individually.

5. List of photos

5 shows a list screen of a digital camera managed by a management company which is a user of the management terminal 18 (the same applies to the processing of the management terminal 20). 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, the display 101 such as camera A, camera B, camera C, etc. on the upper right side of the screen 100 is a list of digital cameras managed by the management company. That is, the ASP server 16 accesses the user attribute database 16d to specify all the digital cameras managed by the administrator, and manages the management terminal 18 for the information of the specific digital camera, for example, the ID of the digital camera. Send to The information of the specific digital camera may be, in addition to the ID of the digital camera, the name of a construction company to which an operator who operates the digital camera belongs. In this screen 100, five digital cameras, digital camera A, digital camera B, digital camera C, digital camera D, and digital camera E, are managed as a digital camera 10 managed by a management company that is a user of the management terminal 18. Is assumed. In addition, in the figure, digital camera A is abbreviated as "camera A". "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. FIG. . The digital cameras A to E may be operated by different workers of the same construction contractor, or may be operated by other workers of different construction contractors. The digital cameras A to E are operated by workers at different construction sites, and take different spot pictures at different timings. In addition, the screen 100 displays a list of image data of the field pictures 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 the field picture. By visually confirming this list of image data, the manager of the management company can easily and collectively grasp the progress of all construction sites. If the manager of the management company, which is the user of the management terminal 18, wants to confirm the on-site photograph taken by the digital camera A, he or she designates the digital camera A on the screen 100 to the ASP server 16. The transmission of the image data is requested. As an example, the screen 100 shown in FIG. 5 is described in HTML format, and the administrator requests the ASP server 16 to transmit the image data photographed by the digital camera A by clicking the displayed "camera A". do.

FIG. 6 shows an example of a screen 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. All project numbers and project names in the folder of the digital camera A are displayed. For example, there are project numbers 1 to 4 in the folder of the digital camera A, and a project name (abbreviated as aaa, bbb, ccc, ddd in the drawing) is displayed with each project number. As described above, the project name indicates the name of the construction site or the name of the building. The administrator designates the desired project number and project name among these. The screen of FIG. 6 can be an HTML screen similarly to the screen of FIG. The administrator requests the ASP server 16 to transmit image data by clicking on any project number or project name.

In FIG. 7, when the administrator designates, for example, the project number 1 and the project name aaa in FIG. 6, an example of the screen transmitted from the ASP server 16 and displayed on the screen 100 of the management terminal 18 is shown. Indicates. All images included in the folder project number 1 of the digital camera A and the project name aaa are displayed. In the figure, image data of nine field pictures represented by P001 to P009 are displayed. The manager can easily grasp the progress of the construction site by visually confirming this screen. In addition, each image data can be displayed together with the shooting date and the project name. Since the project name includes character information indicating the construction site, the administrator can easily check where the image data is and the time when the image data was taken by visually checking the screen of FIG.

6. Slide show

In FIG. 5, a link 102 of a "slide show" is displayed on the lower right side of the screen 100. When the administrator clicks the link 102 of this slide show, the ASP server 16 displays 50 images of which the shooting date and time are new among the image data of the field pictures photographed by the digital cameras A to E managed by the administrator. The data is automatically selected and automatically 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 captures an image of the field photograph taken by the digital cameras A to E. Of the data, 50 pieces of image data having a new shooting date and time 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 predetermined intervals. When sorting by shooting date and time, there are two methods. The shooting date and time are sorted by the oldest, and the shooting date and time are sorted by the newest.

An example of a slide show is shown in FIG. 50 pieces of image data having a new shooting date and time are displayed sequentially from the oldest shooting date and time. First, on the screen 100, image data P001 of a field picture is displayed, along with a digital camera name, shooting date and time, and reception date which are basic information of the image data P001. The digital camera name is the ID of the digital camera. When a predetermined time, for example, 20 seconds elapses after displaying image data P001, image data P002 of a field picture is displayed next, along with the digital camera name, shooting date and time, and reception date and time which are basic information of image data. do. When a predetermined time, for example, 20 seconds has elapsed after displaying the image data P002, the image data P003 of the field picture is displayed next, 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. do. Similarly, image data is displayed on the screen 100 sequentially.

The manager can confirm the progress of the construction site by visually confirming the image data of the field pictures automatically displayed on the management terminal 18 sequentially. In the present embodiment, the latest 50 pieces of image data of the field pictures captured by the plurality of digital cameras A to E managed by the administrator are sequentially displayed. However, the specific digital cameras among the digital cameras A to E are shown. For example, the latest 50 sheets of the image data of the field pictures captured by the digital camera A may be sequentially displayed. In the present embodiment, the latest 50 sheets are displayed in order from the oldest shooting date, but the shooting date and time can be displayed sequentially from the newest.

7. The Matrix

In FIG. 5, a link 103 of "matrix" is displayed at the lower left of the screen 100. When the administrator clicks the link 103 of this matrix, the ASP server 16 collectively displays the image data of the field pictures photographed 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 out the image data of the field picture transmitted from the digital cameras A to E managed by the administrator from the image database 16e, and performs the shooting date and time. The two-dimensional matrix file is created by plotting the presence or absence of image data on a two-dimensional matrix having a type of digital camera as a column. The created two-dimensional matrix file is stored in the file database 16f. The CPU 16b reads out the file of the two-dimensional matrix from the file database 16f and transmits it to the management terminal 18 in response to a request from the management terminal 18.

An example of a matrix display is shown in FIG. The columns of the matrix are taken at the time of shooting, and are divided into yesterday, yesterday, and today, and also divided into time zones of 9 to 12 hours, 12 to 15 hours, and 15 to 18 hours on each day. The rows of the matrix are digital cameras and are divided into digital cameras A through E. In the matrix, when the image data of the field picture exists, a symbol is displayed. For example, in the digital camera A, when there is image data of the field picture at 10 o'clock of yesterday, the symbol ○ is displayed. On the other hand, in the digital camera A, when there is no image data of the field picture whose shooting date and time is yesterday from 12 to 15 o'clock, no symbol is displayed. In addition, the matrix of FIG. 9 is displayed on an HTML screen, for example, and when the administrator clicks a symbol ○, the ASP server 16 requests the corresponding digital camera to transmit image data at a corresponding shooting date and time. Image data is displayed on the screen 100 of the management terminal 18.

By visually confirming the matrix of FIG. 9, the manager can collectively confirm the shooting situation in the digital cameras A to E that he manages. In addition, the manager can visually check the matrix to confirm whether or not an operator who needs to operate the digital camera exists at the construction site. For example, in the digital camera A, it was necessary to take a field photo at 12 to 15 o'clock of yesterday. In this matrix, since the image data of the field photo does not exist in the corresponding time zone, the worker is It can be confirmed that it does not exist. That is, the attendance confirmation of the worker in the field can be easily performed by this matrix.

In addition, since the progress of each construction site can be easily known by using this matrix, it can be seen that the progress of the construction site is smooth at some construction sites, and that construction is not proceeding as planned at a separate construction site. In addition, it is also possible to easily assign workers to construction sites that are not progressing as expected from the construction site where the progress is smooth.
