DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management system for photographs of places that change over time, such as construction sites.

[0002]

2. Description of the Related Art For example, at a site handled in the construction industry, a site manager such as an employee of a construction company inspects various places on the site and checks and confirms the status of construction and the status of settlement with drawings and the like.
Giving instructions to subcontractors is an important role in site management. However, he was distracted by the on-site management and meetings, giving instructions only on the spot, not being able to feed back the results later, or returning to the office from the spot, suddenly remembering and returning to the spot again. There was something like that.

In order to prevent this, a site manager takes a picture of a situation at a predetermined place, for example, a situation of a reinforcement arrangement or a ceiling pipe, so that the situation of the place can be grasped after the photographing.

[0004] As described above, there are many photographs taken on site, and it takes time to organize and it is difficult to identify the location of the photographs after a lapse of time. For this reason, in order to be able to specify the location, date and time, etc. of the photograph taken, conventionally,
The chalkboard on which the shooting location and the date and time are written is shot together with the shooting target, or a photo taken only of the shooting target is attached to an album, and notes on the shooting location and the date and time are written.

[0005]

Therefore, the arrangement is very troublesome, and in the former case, the blackboard may not be used depending on the situation at the site.
With the latter method, if the photo leaves the album,
There is a problem that it is not possible to specify the shooting location, date and time, etc., and these photos are collected and managed individually because the target and purpose are different for each person in charge of the site,
Photo data cannot be shared. An object of the present invention is to solve the above problems.

[0006]

In order to solve the above-mentioned problems, according to the present invention, first, a photograph of a place that changes over time, such as a construction site, is obtained by changing the position of the camera that took the photograph and the photographing direction. The present invention proposes a photograph management system in which an azimuth, an elevation angle, and a date and time are digitally recorded as additional data, and each of the additional data or a matter derived from the additional data can be searched as a keyword.

Further, according to the present invention, a photograph taken of a place that changes over time, such as a construction site, with a camera having a zoom lens is taken into consideration, the position of the camera that took the photograph, the azimuth and elevation angle of the photographing direction, the magnification of the lens, and The present invention proposes a photograph management system in which date and time are digitally recorded as additional data, and each of the additional data or a matter derived from the additional data can be searched as a keyword.

Further, according to the present invention, a photograph taken by a camera having a different focal length of a place that changes over time such as a construction site is determined by the position of the camera that took the photograph, the azimuth and elevation angle of the photographing direction, and the focal length of the lens. The present invention proposes a photograph management system in which the magnification and date of a photograph are digitally recorded as additional data, and each of the additional data or a matter derived from the additional data can be searched as a keyword.

According to the present invention described above, it is possible to specify an object appearing in a photograph, its photographing direction and date and time from the additional data added to each photograph, and these data are digitally recorded. Therefore, the search processing can be easily performed, and the search processing can be performed using each of the additional data or a matter derived from the additional data as a keyword.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view conceptually showing a site photographing system for collecting photograph data which can be applied to the photograph management system of the present invention. The site in this figure shows a building construction site. Reference numeral 1 denotes a temporary wiring along the ceiling 2 of the skeleton under construction, and 3 denotes a light bulb. A transmitter 4 is installed at an appropriate position along the temporary wiring 1. As in the case of the temporary wiring 1 in this example, a plurality of the transmitters 4 are installed at an appropriate place that is relatively difficult to move to the final stage of the construction and have a plurality of fixed coordinates. The transmitter 4 is configured to transmit a signal for giving position information, such as a position as a fixed coordinate and an identification code, to a receiver described later by far infrared rays, ultrasonic waves, or electromagnetic waves, and is well known together with the receiver. , For example, a method of a so-called car navigation system that detects a traveling position of an automobile can be applied.

Reference numeral 5 denotes a camera.
Is a digital camera that records an image projected on an image sensor such as a CCD through a lens 6 as a digital signal on a recording medium 7 such as a magnetic disk, a flash memory card, or a CD. The camera 5 includes the transmitter 4
And a receiver for detecting the receiving position, that is, the position of the camera 5, and detecting means for detecting the azimuth and the elevation angle of the photographing direction. An information recording device for recording on the recording medium 7 together with a digital signal of a photograph image is provided. The camera 5 has a clock like a normal camera, and the information recording device also records the date and time by the clock on the recording medium 7. Each of the above elements is denoted by reference numeral 8
Are installed in the control device shown by, and their illustration is omitted. Reference numeral 9 schematically indicates an antenna. As described above, the specific configuration of the receiver for receiving the signal from the transmitter 4 and detecting the reception position, that is, the position of the camera 5, may be any of the well-known various navigation systems. it can. Such a camera 5
In the detection of the position, the absolute two-dimensional position can be detected by the information of the navigation system and the information specific to the transmitter such as the identification code.
A three-dimensional position can also be detected. For example, in the case of a building, a floor can be specified by adding floor information to the identification code of each transmitter 4. The means used in the car navigation system or the like can be applied to the means for detecting the azimuth and elevation angle of the photographing direction of the camera 5. For example, the azimuth can be detected using a magnet or a geomagnetic sensor, and the elevation angle can be detected using a gyro such as an optical fiber gyro.

The camera 5 having the above configuration is installed on a helmet 10. At this time, the camera 5 is installed such that its shooting direction matches the natural line-of-sight direction of the site manager 11 wearing the helmet 10. According to such an installation method, the site manager 11 can shoot an object to which his / her eyes are directed within the field of view.

In the above configuration, a site manager 11 such as an employee of a construction company wears a helmet 10 and tours various places on the site, and checks and confirms the status of construction and settlement at each location with drawings and the like. Is performed, and the shutter of the camera 5 is actuated by the shutter actuating means as needed to photograph the object to be photographed.

When the photographing is performed in this manner, the information recording device included in the control device 8 is controlled by the receiver to obtain the camera position calculated from the signals from the plurality of transmitters 4 and the azimuth and elevation angle detection means. The detected azimuth and elevation of the photographing direction of the camera 5 and the date and time are recorded as additional data in the recording medium 7 in association with the photographed image.

By such a photographing operation, the site manager 1
1 can easily take a picture of a desired photographing target when looking around various places on the site. Then, the data of each image recorded on the recording medium 7 in this manner is input to a host computer to which the photograph management system according to the present invention is applied and managed after a look around.

The camera 5 can be provided with a zoom lens. With this zoom lens, an object can be photographed at different magnifications. In this case, the camera 5 is provided with a unit for detecting the magnification of the zoom lens,
The magnification is recorded by the information recording device together with the image as additional data to be added to the additional data, whereby images having different magnifications can be mixed and processed.

The camera 5 can be configured such that lenses having different focal lengths can be switched, and the switchable lens can photograph an object to be photographed at different magnifications.
In this case, the camera 5 is provided with means for switching to detect a lens in use, and the magnification of the image is recorded by the information recording device together with the image as additional data to be added to the additional data. Thus, it is possible to mix and process images having different magnifications.

The collection of image data does not necessarily require the use of the above-described photographing system. For example, a photograph is taken by a camera in the same manner as in the related art, and data corresponding to the additional data is stored in each photograph. Each image is described as a memo, and the photograph is digitized and input by the image data input function constituted by the host computer or other appropriate personal computer, and the contents described in the memo are input as additional data. Thereby, data applicable to the photograph management system according to the present invention can be created and collected. The data thus created and collected can be input to the host computer in the same manner as described above.

When data of each image is input to the host computer, an unnecessary data exclusion function can be provided in the input process. This unnecessary data exclusion function performs, for example, the following processing. a. Exclude out of focus data and do not enter. b. Exclude underexposed data and do not enter. c. If the date and time of the newly input data is within the preset time and the date and time of the already input data, the old data is deleted and new data is input. With the unnecessary data exclusion function described above, only appropriate data can be input and managed.

As described above, with respect to a large number of pictures input to the host computer, it is possible to specify the object in the picture, its shooting direction, and the date and time from the additional data added to each image. Since these data are digitally recorded, a search process can be easily performed. In the search process, each of the additional data or a matter derived from the additional data can be performed as a keyword.

For example, as a search process, a search can be performed by using each position of the site, the date of photographing, and the like as a keyword to easily extract a corresponding image. The extraction of the image can be easily performed even after the lapse of time, such as construction progress documents and maintenance reference data. In the above search processing, the position information in the additional data can be converted from the three-dimensional coordinate values and the photographing direction into position information corresponding to a drawing of a building or the like. The date and time information can be compared with the progress of the construction by illuminating the process information. Therefore, the image search can be performed by a method of designating the position of the drawing or the like and the timing of the process. From the above, in the present invention, it is possible to easily organize photos, including those hidden by the progress of the process, for example, reinforcing members, structural members such as steel frames, equipment, air conditioning and electric piping, Since a large number of photos can be stored in such a form, it is possible to know the exact present situation of the building without going to the site and conducting a survey when planning a building renewal or the like, for example.

Therefore, in the present invention, collection of photographic data relating to the construction status of the building
In addition to management, by associating the position information according to the present invention with the map information, application to an environmental information database for city planning, application to landscape design using data of cityscape photographs, planning It can be applied to simulation of landscape view from building windows.

In the above-described search processing, a tag can be generated for each data according to the search purpose. For example, application to a database relating to the construction status of a construction site is as follows. a. From the building design information, tags for identifying floors, rooms, and parts are generated. b. From the process information, a tag for identifying a type of construction such as a skeleton, a finish, or equipment is generated. The application of urban environmental information to a database is as follows. a. A tag for converting the above-described three-dimensional position coordinates into the coordinate system of the map information is generated. b. Generate a tag for determining the range of view in light of the map information.

Using such a tag, the following search can be performed. First of all, in the application to the database on the construction status of construction sites, drawings, floors,
A required image can be specified and searched in a room / part list, a process, and the like, and a required image can be extracted. Further, in the application of the environmental information of a city to a database, a necessary image can be specified and searched in map information according to the purpose, and a necessary image can be extracted.

On the other hand, in displaying the image data extracted by the search, the following functions can be applied. a. As the zoom function, images before and after a certain time interval are displayed. b. As a panning function, images at upper, lower, left, and right positions within a certain time interval are continuously displayed. c. As a fast-turn display function, images at the same place are displayed continuously over time.

In displaying the above image data, the following image correction function can be applied. a. At the time of display to which the panning or fast-turn function is applied, adjustment is performed so that the size of the shooting target (subject) becomes constant. b. At the same time, correct the color and exposure of the image.

Next, the function of outputting the extracted image can be applied, for example, by dividing the image into a place, a type of work, a process, and the like, and organizing and outputting the image.

[0028]

As described above, the present invention has the following effects. a. It is possible to manage a large number of photographs taken of a place that changes over time, such as a construction site, so that a plurality of persons can use the photographs according to their individual purposes. b. From the data of each photo, the location of the photo can be specified, the current situation of the site and the like can be efficiently grasped after the photographing, and the transition of the construction and the like can be grasped accurately. c. It is possible to easily find a specific image in a record whose date and time has elapsed, such as a construction record.
