(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

FIG. 1 is a diagram showing the configuration of a building diagnosis system according to an embodiment of the present invention.

In the figure, 1 is a video camera equipped with a cross-point finder and whose imaging magnification is variable, and which images the entire building and a local part of the building; 2 is a camera that drives this video camera 1 vertically and horizontally. Drive device, 3
25 is an angle sensor that detects the vertical and horizontal angles of the video camera 1 driven by the camera drive device 2 from a predetermined reference position, and 25 is a magnification detection device that detects the imaging magnification of the video camera. .

Further, 4 indicates a main unit.

This main unit 4 has a CPU 5 that centrally controls the entire system, a ROM 6 that stores programs necessary for the operation of the CPU 5, a RAM 7 that stores various data during the operation of the CPU 5, and stores image data captured by the video camera 1. It is composed of an image buffer 8 and the like. In addition, 9~
14.26 is I/F for interfacing with external equipment
These parts are connected via a bus 15.

Further, 16 is a CRT, 17 is a printer, and 18 is a keyboard.

Next, the operation of the building diagnosis system configured as described above will be explained.

First, as shown in FIG. 2, the video camera 1 is set at a predetermined distance from the building 19.

In this case, it is preferable to measure and record the position of the video camera 1 with respect to one building.

This is to enable comparison of imaging results after the fact.

Next, the entire imaging mode is set by operating the keyboard 18, and the position information of at least three points (two points above and below from a predetermined reference position and the angle with respect to the horizontal direction) indicating the entire range of the object to be imaged is set by operating the keyboard 18. An input is made from the angle sensor 3 to the main unit 4.

For example, in the example shown in FIG. 2, the entire building 19 is used as the entire object to be imaged, and the left and right parapet ends 20, 21 and the lower end 22 of the left outer wall are used as the position information of the three points.

The position information of these three points is stored in the RAM 7.

Next, the range to be imaged of the entire object to be imaged, ie, the building] 9, is imaged by the video camera 1.

This is done by the camera driving device 2 causing the video camera 1 to scan vertically and horizontally under the control of the CPU 5.

The image data of the entire object to be imaged, which has been manually captured by the video camera 1 in this way, is stored in the image buffer 8. Further, the imaging magnification of the video camera 1 when capturing the entire image is detected by the magnification detection device 25 and stored in the RAM 7.

Thereafter, the local imaging mode is set by operating the keyboard 18, and the video camera 1 images a desired position of one building, which is the local area of the object 3 to be imaged.

At that time, the CPU 5 outputs the position information of the three points, the imaging magnification of the video camera 1 at the time of overall imaging, the current position information of the video camera 1 output from the angle sensor 3, and the magnification detection device 2.
Based on the current imaging magnification of the video camera 1 detected by 5, the building 1 currently being imaged as seen from the entire building 19.
Calculate the imaging range of 9 local areas.

Then, as shown in FIG. 3, the CRT 16 is caused to display the imaging results of a local part of the building 19, and the imaging results of the entire building 19 stored in the image buffer 8 are displayed at the lower right of the screen. Also, based on the above calculation results,
The imaging range of a local part of the building 19 viewed from the entire building is displayed as shown by diagonal lines in FIG.

In this way, the building diagnosis system of this embodiment displays the imaging results of the entire building and the imaging results of a local part of the building 19, and also displays the imaging range of the local part of the building 19 from the perspective of the entire building 19. Therefore, when enlarging an image of a local part of the building 19, the imaging position of the local part of the building 19 can be easily determined from the perspective of the entire building 19.

Incidentally, the imaging of a local part of the building 19 may also be performed by the camera driving device 2 causing the video camera 1 to scan vertically and horizontally under the control of the CPU 5.

When imaging a local part of the building 19, an address may be provided for each imaging result, and then this address may be used to repeatedly image the same imaging position.

Next, an application example of this building diagnosis system will be explained.

As one example, within the local area of the building 19 imaged by the laser light emitting device that emits laser light and the video camera in the above embodiment, the laser light is emitted so as to form a lattice as shown in FIG. A scanning device that scans the laser light emitted by the device is added to the above-described building diagnosis system.

Then, within the local area of the building 19 imaged by the video camera, there is a bending or bulging shade. As shown, distortion occurs.

As described above, in this system, the imaging position of a local part of the building 19 can be easily determined from the perspective of the entire building 19, and therefore, the position of a bend, bulge, etc. can be easily discovered.

Note that this application example can also be realized by using a lens system that forms a similar grating instead of the scanning device.

Next, another application example will be explained based on FIG.

In the figure, 1 is a video camera in the above-described embodiment system, 23 is an infrared temperature sensor that grasps the temperature distribution of the imaging light based on the infrared rays contained in the received imaging light, and 24 is the building imaged by the video camera 1. Thing 19
It is a half mirror that splits the imaging light from the reach into the video camera 1 and the infrared temperature sensor 23.

Then, the imaging light of the building 19 local area (1, 1, half mirror 24 is used to connect the video camera 1 and the infrared temperature sensor 23
It is spectrally divided into two parts.

At this time, in the infrared temperature sensor 23, the temperature distribution of the imaging light is disturbed, and it is possible to detect an abnormality in the building 19.

On the other hand, the position of the difference, ili, is determined by the above-described embodiment system including the video camera 1.

In particular, when the inspection is performed using the infrared temperature sensor 23, it is necessary to perform local imaging as in the above-mentioned embodiment for the reason of accuracy, so it is difficult to determine the imaging position.

Therefore, this problem can be avoided by making it easy to separate the positions by 'I'll' as in the above-described embodiment.

Next, another embodiment will be described.

The system configuration according to this embodiment is similar to that shown in FIG. 1, but the operation is different.

The operation will be explained below.

First, a video camera is set at a predetermined distance from the building.

Next, set the overall imaging mode 7 by operating the keyhole 1' 18, and input position information (angles from the vertical direction and downward direction from a predetermined reference position) of at least three points indicating the entire range of the object to be imaged using the keyboard. By operating 18, the main body device 4 is manually operated from the angle sensor 3.

The position information of these three points is recorded in the RAM 7.

Next, the video camera 1 images a range of the building 19, which is the entire object to be imaged.

This is done by causing the camera drive device 2 or video camera to scan vertically and horizontally under the control of the CPU 5.

The image data of the entire object to be imaged inputted by the video camera in this way is stored in the f-mount 1 image buffer 8.

Further, the imaging magnification of the video camera 1 when capturing the entire image is detected by the magnification detection device 25 and stored in the RAM 7.

Thereafter, the local imaging mode is set by operating the keyboard 18, and the video camera 1 images the local part of the object to be imaged, which is the four parts of a building]9.

] 8 At that time, the CPU 5 uses the positional information of the three points, the imaging magnification of the video camera 1 during overall imaging, the current positional information of the video camera 1 output from the angle sensor 3, and the current imaging magnification of the video camera 1. Based on this, the imaging range of the local part of the building 19 currently being imaged as seen from the entire building 19 is calculated.

Then, among the imaging results of one entire building stored in the image buffer 8, the imaging range calculated as described above is replaced with the imaging result of a local part of the building 19 corresponding to the imaging range.

Therefore, according to this embodiment system, the building 19
It is possible to make dark portions of the entire imaging result bright and easy to see.

That is, in the normal video camera 1, since the exposure is corrected according to the imaging screen, the position of the concave portion in the imaging result of the entire building 19 becomes dark and difficult to see.

On the other hand, this is because the exposure of the imaging result of the replaced recess has a normal brightness depending on the position of the recess.

]9 Next, an embodiment of the drawing creation system of the present invention will be described.

The system configuration according to this embodiment may be the same as that shown in FIG. 1, or may differ in operation.

The operation will be explained below.

First, the video camera 1 is set at a predetermined distance from one building. In addition, the height of an arbitrary part of the building 19, for example, the frontage, is actually measured in advance, and this dimension value is used for the keyboard 1.
The information is input to the main device 4 by the operation in step 8.

Next, use the keyboard 18 to set drawing creation mode, and trace the outline of the building 19 (including the parts that should be shown in the drawing, such as windows) using the center cross point shown on the cross point finder of the video camera 1. .

Trajectory information output from the angle sensor 3 by tracing the contour in this manner is input to the main device 4.

In the main device 4, this trajectory information is stored in the RAM 7.

0 When the work of tracing the outline is completed in this way, the entire image is displayed on the CRT 16 by operating the keyboard ]8.

Since this overall image is better than the result of imaging from a position separated by a predetermined distance, as shown in FIG. 7(a),
Looks perspective.

The CPU 5 uses a predetermined program to perform correction based on the locus information that can be seen in a perspective view so as to obtain a true drawing as shown in FIG. 7(b).

Furthermore, the CPU 5 determines the dimensions of each part using a predetermined program based on the dimension values of any part of one building that have been actually measured and manually performed in advance.

Then, the printer 17 outputs a drawing as shown in FIG. 7(C).

Therefore, the system of this embodiment has the following effects.

That is, in building diagnosis, drawings are often required.

However, there are cases where there are no drawings of the building, or where the shape of the current building differs from the new construction or renovation drawings.

Therefore, if this embodiment system is used, the drawing can be easily restored and the above problem can be solved.

The present invention can be further considered to have the following application examples.

For example, the system shown in FIG.
9 local areas are imaged using τ1. of the CPU 5. Under the legs, the camera driving device 2 causes the video camera 1 to scan vertically and horizontally, and as a result images the entire area.

Next, the overall situation is synthesized based on these image data. After this, the identity correction described above is performed. The results are then output from a CRT or printer. In this case, local imaging using laser light or infrared rays as described above may be similarly performed, and the results may be output from a CRT or printer. Alternatively, the image may be output as is without performing identity correction.

In each of the embodiments described above, the present invention was applied to the field of building diagnosis, but it can also be applied to fields such as microscopic photography and ruin investigation.

Moreover, the technical means of the present invention is not limited to the two consecutive embodiments, but can be applied within the scope of the technical idea.

[Effects of the Invention] As explained above, according to the present invention, the imaging results of the entire object to be imaged and the imaging results of a local part of the object to be imaged are displayed, and the imaging range of the local part of the object to be imaged viewed from the entire object to be imaged is displayed. Since it is displayed, when enlarging a local part of the object to be imaged, it is possible to easily determine the imaging position of the local part of the object to be imaged from the perspective of the entire object to be imaged.
