(Example) Hereinafter, details of an example of the present invention will be described with reference to the drawings.

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

In the figure, reference numeral 1 denotes a video camera which is mounted with a cross point finder and whose imaging magnification is variable, and which captures an image of the entire building and a local part of the building, and 2 denotes a camera which drives the video camera 1 vertically and horizontally. Drive,
Reference numeral 3 denotes a video camera 1 driven by the camera driving device 2
An angle sensor 25 detects an angle with respect to the vertical and horizontal directions from a predetermined reference position, and a magnification detection device 25 detects the imaging magnification of the video camera 1.

 Reference numeral 4 denotes a main unit.

The main unit 4 controls the entire system in a centralized manner.
CPU5, RO that stores programs required for the operation of CPU5
M6, a RAM 7 for storing various data when the CPU 5 operates, an image buffer 8 for storing image data from the video camera 1, and the like. Reference numerals 9 to 14 and 26 denote I / F sections for interfacing with external devices.
Connected through 5.

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

Next, the operation of the thus constructed building diagnostic system will be described.

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

At this time, it is preferable that the position of the video camera 1 with respect to the building 19 be measured and recorded. This is to make it possible to compare the imaging results after the fact.

Next, the whole image capturing mode is set by operating the keyboard 18, and at least three pieces of position information (angles with respect to the vertical and horizontal directions from a predetermined reference position) indicating the range of the entire object to be imaged are angled by operating the keyboard 18. Input is made from the sensor 3 to the main unit 4.

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

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

Next, the video camera 1 captures an image of the building 19 which is the entire object to be imaged.

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

As described above, the image data of the entire object to be imaged input by the video camera 1 is stored in the image buffer 8. Further, the imaging magnification of the video camera 1 at the time of the whole imaging is detected by the magnification detecting 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 the building 19 which is a local portion of the object to be imaged.

At that time, the CPU 5 determines the position information of the three points, the imaging magnification of the video camera 1 at the time of the entire imaging, the current position information of the video camera 1 output from the angle sensor 3 and the current position information detected by the magnification detection device 25. Based on the imaging magnification of the video camera 1, the imaging range of the local part of the building 19 currently being imaged as viewed from the entire building 19 is calculated.

Then, as shown in FIG. 3, building 1
The imaging results of the nine localities are displayed, and the imaging results of the entire building 19 stored in the image buffer 8 are displayed at the lower right of the screen. In addition, based on the above calculation results,
The imaging range of the 19 building 19 viewed from the whole 19 is displayed as shown by hatching in FIG.

Thus, in the building diagnosis system of the present embodiment, the imaging result of the entire building 19 and the imaging result of the local area of the building 19 are displayed, and the imaging range of the local area of the building 19 viewed from the entire building 19 is displayed. Therefore, in the case of enlarging and imaging the local portion of the building 19, the imaging position of the local portion of the building 19 as viewed from the entire building 19 can be easily determined.

The imaging of the 19 local portions of the building may be performed by the camera driving device 2 scanning the video camera 1 vertically and horizontally under the control of the CPU 5.

For imaging of the 19 local portions of the building, an address may be provided for each imaging result, and then the same imaging position may be repeatedly imaged using this address.

Next, an application example based on the building diagnosis system will be described.

One of them is a laser light emitting device that emits laser light and a laser light emitting device that forms a grid as shown in FIG. 4 within a local area of a building 19 imaged by the video camera 1 in the above-described embodiment. A scanning device that scans the laser light emitted by the device is added to the building diagnostic system described above.

Then, when there is an abnormality such as bending or swelling in the range of the 19 local portions of the building imaged by the video camera 1, the lattice formed by the laser light imaged by the video camera 1, as shown in FIG. Distortion occurs.

As described above, in this system, since the imaging position of the local part of the building 19 viewed from the whole building 19 can be easily determined, an abnormal position such as bending or bulging can be easily found.

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

 Next, another application example will be described with reference to FIG.

In the figure, reference numeral 1 denotes a video camera in the above-described embodiment system, 23 denotes an infrared temperature sensor for grasping a temperature distribution state of imaging light based on infrared light included in received imaging light, and 24 denotes a building imaged by the video camera 1. This is a half mirror that splits the imaging light of the local object 19 into the video camera 1 and the infrared temperature sensor 23.

Then, the imaging light of the local part of the building 19 is split by the half mirror 24 into the video camera 1 and the infrared temperature sensor 23.

At this time, the infrared temperature sensor 23 can detect an abnormality in the building 19 based on the temperature distribution of the imaging light.

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

In particular, when the inspection is performed using the infrared temperature sensor 23, it is necessary to perform the local imaging in the above-described embodiment for reasons such as accuracy, and it is difficult to determine the imaging position. Therefore, this problem can be avoided by easily determining the position as in the above-described embodiment.

 Next, another embodiment will be described.

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

 Hereinafter, the operation will be described.

First, the video camera 1 is set at a predetermined distance from the building 19.

Next, the whole image capturing mode is set by operating the keyboard 18, and at least three pieces of position information (angles with respect to the vertical and horizontal directions from a predetermined reference position) indicating the range of the entire object to be imaged are angled by operating the keyboard 18. Input is made from the sensor 3 to the main unit 4.

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

Next, the video camera 1 captures an image of the building 19 which is the entire object to be imaged.

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

As described above, the image data of the entire object to be imaged input by the video camera 1 is stored in the image buffer 8. Further, the imaging magnification of the video camera 1 at the time of the whole imaging is detected by the magnification detecting 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 captures an image of, for example, a concave portion of the building 19, which is the local portion of the object.

At that time, the CPU 5 determines the position information of the three points, the imaging magnification of the video camera 1 at the time of the whole imaging, the current position information of the video camera 1 output from the angle sensor 3 and the current imaging magnification of the video camera 1. Then, the imaging range of the local part of the building 19 currently being imaged as viewed from the entire building 19 is calculated.

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

Therefore, according to this example system, the building 19
It is possible to make the darker part of the whole imaging result bright and easy to see.

That is, in the ordinary video camera 1, since the exposure is corrected in accordance with 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, the exposure of the imaging result of the replaced concave portion has a normal brightness corresponding to the position of the concave portion.

Next, an embodiment according to the drawing creation system of the present invention will be described.

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

 Hereinafter, the operation will be described.

First, the video camera 1 is set at a predetermined distance from the building 19. Further, an arbitrary portion of the building 19, for example, the height of an opening is actually measured, and the dimension value is input to the main unit 4 by operating the keyboard 18.

Next, the drawing mode is set by operating the keyboard 18, and the outline of the building 19 (including a portion such as a window to be shown in the drawing) is traced by the center cross point shown in the cross point finder of the video camera 1.

The trajectory information output from the angle sensor 3 by tracing the contour in this manner is input to the main unit 4.

 In the main unit 4, this locus information is stored in the RAM.

When the operation of tracing the contour is completed as described above, the entire image is displayed on the CRT 16 by operating the keyboard 18.

Since this whole image is based on the result of imaging from a position separated by a predetermined distance, it looks like a perspective view as shown in FIG. 7 (a).

Based on the trajectory information that looks like a perspective view, the CPU 5 performs a correction using a predetermined program so that a true drawing as shown in FIG. 7B is obtained.

Further, the CPU 5 determines the dimensions of each part by using a predetermined program based on the dimensional values of arbitrary parts of the building 19 which are read and measured and input.

Then, a drawing as shown in FIG. 7C is output from the printer 17.

Therefore, the system according to this embodiment has the following effects.

That is, drawings are often required for building diagnosis.

However, there is a case where there is no drawing of the building or a case where the shape of the current building is different from the new construction drawing or the renovation drawing.

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

 The present invention has the following application examples.

For example, the building shown in FIG.
Under the control of the CPU 5, the camera driving device 2 causes the video camera 1 to scan the video camera 1 in the vertical and horizontal directions under the control of the CPU 5, so that the entire image is captured.

Next, the overall situation is synthesized based on these image data. Thereafter, the above-described identity correction is performed. Then, the result is output from a CRT or a printer. In this case, the above-described local imaging using the laser light or the local imaging for infrared may be performed in the same manner, and the result may be output from a CRT or a printer. Alternatively, the data may be output as it is without performing the identity correction.

In each of the embodiments described above, the present invention is applied to the field of building diagnosis, but can be applied to fields such as microscopic photography and archeological research.

Further, the technical means of the present invention is not limited to the above-described embodiment, but can be applied within the scope of the technical idea.

[Effects of the Invention] As described above, according to the present invention, the imaging result of the entire imaging target and the imaging result of the imaging target local portion are displayed, and the imaging range of the imaging target local portion viewed from the entire imaging target is changed. Since it is displayed, when magnifying the local portion of the object to be imaged,
It is possible to easily determine the imaging position of the local portion of the object viewed from the entire object.
