The system setting data 300 includes, for example, user information regarding the authentication and authority of the administrator U1 and the worker U2, work site information regarding the work site, and image capturing apparatus information regarding the image capturing apparatus 2. FIG.

In the user information, a user name, e-mail address, password, access authority, etc. are registered for each administrator U1 and each worker U2.

A site name, a floor name, and a floor layout are registered in the work site information. The floor layout is, for example, a plan view of a work site, and in the case of a multistory building, a plan view of each story. A floor layout may be created, for example, by converting from two-dimensional or three-dimensional CAD data of a building that serves as a work site.

The image capturing device information includes, for each image capturing device 2, the image capturing device name, the installation position where the image capturing device 2 is installed, the capturing conditions when the image capturing device 2 captures the captured data, and the image capturing data. A transmission condition when the apparatus 2 transmits photographed data is registered. For the image capturing device name, for example, a unique identifier or name for identifying the image capturing device 2 is registered. As the installation position, position coordinates with a predetermined reference position in the floor layout as the origin may be registered, or position names such as room names, section names, floor names, and floor numbers may be registered.

For example, the set time when the image capturing device 2 captures the entire surroundings of itself is registered as the capturing condition. For example, month, day, hour, minute, second, time interval, day of the week, period, time zone, etc. are registered as the set time. For the set times, for example, a plurality of times in a day may be registered. In that case, a plurality of times may be registered. For example, a time interval such as a 5-minute interval may be registered. good. Note that the image format of the photographed data and the resolution of the photographed data may be further registered in the photographing conditions.

For example, the computer name and folder name of the image data management device 3 are registered as the transmission destination of the image data. The transmission timing of the photographing data includes, for example, immediately after photographing the photographing data, adding a fixed time (for example, 10 seconds) to the photographing data immediately after photographing, or adding a fixed time (for example, 10 seconds) to the photographing data immediately after photographing. A random time addition or the like that adds a time (eg, a number of seconds randomly taken from 1-60 seconds) is registered. By setting fixed-time addition or random-time addition, it is possible to suppress simultaneous transmission of captured data from a plurality of image capturing devices 2, thereby reducing the processing load associated with communication and data reading and writing. Furthermore, the number of simultaneous transmission data may be registered as a setting for collectively transmitting a plurality of pieces of image data in the transmission timing of the image data.

FIG. 4 is a data configuration diagram showing an example of the imaging data management database 301 according to this embodiment. The photographed data management database 301 stores photographed data photographed by the image photographing apparatus 2 in association with the photographing attribute when the photographed data was photographed. In this case, the shooting attribute may be stored as digital data separate from the shooting data and associated with the shooting data by a unique identifier or file name given to each shooting data, or may be a part of the shooting data. It may be associated with the photographed data by being included in each piece of photographed data as a property (for example, property).

The photographing attribute registers the photographing position corresponding to the installation position of the image photographing device 2 and the photographing time corresponding to the set time. For example, position coordinates and position names are registered in the photographing position in the same manner as in the installation position. For example, year, month, day, hour, minute, second, etc. are stored as shooting time in the same manner as the set time.

Note that the work sites to be managed by the photographed data management device 3 may be a plurality of work sites. In that case, the system setting data 300 and the imaging data management database 301 are managed for each work site.

By executing the image data management program 302, the control unit 31 functions as a setting management unit 310, an image data management unit 311, and a screen information provision unit 312, as shown in FIG.

Register the information of Then, the setting management unit 310 sets the imaging conditions and transmission conditions stored in the system setting data 300 to the image capturing device 2 . Specifically, the setting management unit 310 transmits the shooting conditions and transmission conditions for each image shooting device 2 stored in the system setting data 300 as a setting command to each image shooting device 2, thereby performing each image shooting. The imaging conditions and transmission conditions of the device 2 are set. As a result, each image capturing device 2 captures an image of the entire surroundings of itself according to the capturing conditions, and transmits the captured image data according to the transmission conditions. 301 is stored.

The photographed data management unit 311 stores and manages the photographed data photographed by the image photographing device 2 according to the photographing conditions in the photographed data management database 301 in association with the photographing attribute when the photographing data was photographed.

Note that part or all of the imaging data management database 301 may be stored in, for example, an external storage device (may be plural) or a storage medium (may be plural) instead of the storage unit 30, in which case , the imaged data management unit 311 may access the imaged data management database 301 via the communication unit 34 and the device connection unit 35 . Further, the photographed data management unit 311 may receive an input operation for deleting part or all of the photographed data from the administrator terminal device 4 and delete the photographed data from the photographed data management database 301 in accordance with the input operation. Alternatively, photographed data that satisfies a predetermined deletion condition (for example, whether or not a predetermined period of time has elapsed since the photographing time) may be automatically deleted from the photographed data management database 301 .

Also, the photographed data management database 301 may be composed of a plurality of databases, for example, a first database that stores the photographed data of the current day and a second database that stores the photographed data of the previous day and earlier. In this case, the photographed data management unit 311 may perform batch processing during the nighttime to transfer the photographed data of the current day from the first database to the second database.

The screen information providing unit 312 receives viewing conditions for viewing photographed data from the administrator terminal device 4 or the worker terminal device 5, and photographs the photographed data associated with the photographing attributes that match the viewing conditions. It extracts from the data management database 301 and provides screen information for displaying the extracted photographed data to the manager terminal device 4 or the worker terminal device 5 that accepts the viewing conditions.

The viewing conditions include, for example, at least one of a viewing position corresponding to the photographing position of the image capturing device 2 and a viewing time corresponding to the photographing time. Note that the viewing conditions may further include a viewing orientation indicating a specific orientation in the entire circumference.

For example, when the screen information providing unit 312 receives at least one of the viewing position and the viewing time as the viewing conditions, the screen information providing unit 312 is associated with the shooting position and shooting time that match the viewing position and the viewing time. Screen information is provided based on the shooting data.
