Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction video editing apparatus suitable for editing images sequentially captured in a building construction process.

[0002]

2. Description of the Related Art It is necessary to record the images of buildings under construction one after another with a camera or a video camera.
During the construction period, it is possible to immediately know the progress of the construction by its self-explanatoryness, and after the construction, the construction record not only serves as a reference for the construction method, cost, construction period, etc. in the subsequent construction work, but also in particular It is also a magnificent non-fiction drama for large-scale construction work, and may have significance as a cultural record.

[0003]

However, in general, in this type of video recording, the date and time when the image was taken, the place, the imaged part, etc. were clearly specified, and the value of the data would be halved if no distinction was made. It also causes confusion during editing.

In this respect, the relatively latest cameras and video cameras have a date display function, but the shooting location still depends on the photographer's records,
This kind of data tends to be incomplete, and the photographer may not be able to determine which part of which building is being photographed, or may be confused with misunderstanding.

That is, even in the same building, the appearance is completely different depending on the position, distance, and angle of the image, and many similar portions make post-processing complicated.

By the way, in Japanese Patent Laid-Open No. 5-207408, a photographed optical image is converted into a digital image.
As an electronic still camera that records in a memory, a camera provided with a function of specifying a position at the time of shooting is disclosed. This is to identify a shooting position by GPS (a system for receiving radio waves oscillated from a plurality of artificial satellites and knowing the position such as latitude and longitude of a receiving place), and record the position data together with image data in a memory. It is suitable for editing because it can be classified and searched by place.

In this case, however, the latitude, longitude and altitude of the shooting location are determined, but it is necessary to convert the specific location, that is, which floor of which building and which location. It cannot be determined which part was taken.

Therefore, the present invention is intended to solve the above problems, and its purpose is to display the location and part of a photographed subject in a concrete form, thereby showing the progress status of construction. This is to provide a method of editing a construction image suitable for knowing.

[0009]

In order to achieve the above object, a method of editing a construction image according to the present invention comprises an image pickup device for picking up an image of a subject such as a building under construction and recording it on a recording medium.
Means for detecting position information of the image pickup apparatus at the time of image pickup, means for detecting the azimuth, elevation angle and distance of the subject with respect to the image pickup apparatus, and photographing date / time recording means are provided. An image forming apparatus that records the image information of the subject on a recording medium together with the shooting date and position of the image as numerical information, and an editing apparatus that edits the image information by type from the image information and the numerical information recorded on the recording medium. The editing device includes a subject determination system having built-in three-dimensional space data representing a construction area and a space occupied by a building part created in advance as a three-dimensional graphic display, and generation time data of the space. An image and numerical information of a recording medium, and the three-dimensional space data and the space generation time data built in the recording / editing device. By comparison, it is characterized in converting the numerical information to the name of a specific shooting location and shooting site.

The invention according to claim 2 is characterized by further comprising means for detecting a depression angle and a distance in addition to the azimuth of the subject with respect to the image pickup device.

[0011]

According to the above method, the accurate numerical information of the subject is recorded in the recording medium together with the image information, and the editing device takes in the contents recorded in the recording medium, and stores the three-dimensional space data built in the recording medium. In addition to comparing the image information recorded on the recording medium and the numerical information thereof, the date and time in the numerical information of the subject and the spatial occurrence time data are compared to search for the photographing position and site, and the specific photographing position and photographing are performed. Convert the part to a name, store it as a database with image information,

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an outline of a system of an apparatus according to the present invention. An image forming apparatus 1 includes a camera 2 and a GPS.
3, a lightwave distance meter 4, an electronic timepiece 5, and a CPU 7 that controls the electronic timepiece 5 and these, and stores the data obtained from each in a memory 6 (recording medium). The data stored in 6 is read by the editing device 8 and edited by type.

The camera 2 is a so-called electronic still camera, and as an example, as shown in the drawing, an optical system such as a lens 10 directed to an object A such as a pillar-beam junction in a building and a rear portion thereof are arranged. A driving system 12 such as a shutter and a CCD 11 that outputs an electric signal corresponding to the brightness and color of the image of the subject A input from the optical system is provided.

The GPS 3 is built in the camera 2 or arranged in the vicinity of the camera 2 and is a system for receiving the radio waves oscillated from a plurality of artificial satellites to know the position of the receiving place as described above. , The receiving antenna 14 and the signals from the artificial hygiene received by the antenna 14 are longitude, latitude,
And a position calculation circuit 15 for converting into altitude data.

The light wave range finder 4 is located in the vicinity of the camera 1 and has a detection surface directed parallel to the tip of the lens 10.
The distance from the camera 1 to the subject A is measured, and the azimuth meter and the inclinometer detect the azimuth and the elevation angle (in some cases, only the azimuth). These data are input to the subject position calculation circuit 16 together with the data obtained by the GPS 4. The arithmetic circuit 16 calculates the position and altitude of the subject 16 in accordance with the current position of the camera 2, the distance between the subject A and the altitude, the azimuth, and the elevation angle. When the distance of the subject A is short, the focal length information of the camera can be used.

The electronic timepiece 5 ticks the date and time every second, and is built in the normal date display function, and the memory 6 is a fixed memory built in the camera 1 or an IC memory card in the camera 1. It is detachably attached.

When the driving system 12 is driven by the user pressing the shutter, the CPU 7 calls the image information converted into an electric signal by the CCD 11 and stores it in the memory 6 and forms a pair with this image information. The output contents from the position calculation circuit 15, which is various management information, that is, the current position of the camera, the altitude information, and the calculation contents from the calculation circuit 16, that is, the position and altitude information of the subject 1, the date, the time information, are called. Then, it is stored in the memory 6 as a numerical value.

If necessary, this content is called as shown in the figure and displayed on the monitor 8a. Can be displayed.

Therefore, the determination system 20 takes in the contents of the memory 6 (through the reading device in the case of an IC memory card, through the reading terminal portion in the case of a fixed memory built in the image forming apparatus 1), and The three-dimensional space data 21 and the generation time data 22 of the space
The shooting position and the subject position are searched from, and the numerical values X, Y,
Convert Z to a concrete name.

That is, from the process table of the space generation time data 22 and the shooting date and time on the memory 6 side, it is determined how many floors the building is at the time of the shooting, and the shooting position numerical values X, Y,
From Z, it is determined on which floor and in which place the building was photographed.

When the number of floors and the place of the building are specified, as an example, the three-dimensional space data 21 cut out on the floor is compared with the image as shown in the figure. In this case, the image of the subject A is only the column-beam joint portion, and there are four such portions as compared with the spatial data 21, and it is not possible to determine which portion as it is. However, spatial data 2
1 turns the model along the numerical values X, Y, and Z of the imaging direction, and whether or not the image of the object A is superposed and coincident is determined, and the imaging direction of the object A is determined. It is determined which one of the four positions is located.

The determination system 20 is selected according to the determination result.
Is a specific name for the numerical contents of the photographing location and the subject position recorded in the memory 6, for example, the photographing location: the third floor,
It is converted into a concrete name such as the subject pillar 3FC3 and registered in the storage unit together with the image as the image database 23, or displayed on the monitor 8a as necessary.

In the figure, as an example, an example in which the image of the subject A is rewritten in the database 23 with specific names, for example, shooting location: 3rd floor, subject: pillar 3FC3, is shown.

Further, the collected database 23 can be categorized and edited individually. The contents of the program include editing by date, photographing position, photographing region, and the like. When it is desired to view the screen in order of the year, month, and day only for a certain part, only the image information is selected by the selecting operation in the order of the year, month, day and date on the monitor television 8a.
In addition, the necessary image information can be searched and edited according to various classifications by the selection operation.

[0029]
