Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying instrument with an image pickup device capable of acquiring both survey data such as distance, angle, coordinates, etc., to a survey target and image data of the survey target.

[0002]

2. Description of the Related Art FIG. 12 is a block diagram of a conventional surveying instrument. The surveying instrument has an axis 1 for rotating the telescope 11 horizontally.
And a shaft 2 for vertical rotation are arranged so as to intersect at a rotation center 3 of the telescope 11, and an angle measurement mechanism 4 for detecting a horizontal rotation angle of the telescope 11 and a measurement mechanism for detecting a vertical rotation angle A corner mechanism 5 is provided.

The surveying instrument further has a built-in distance measuring mechanism 6 which shares a part of the optical system with the telescope 11, and has a computer 7 for controlling the angle measuring mechanisms 4, 5 and the distance measuring mechanism 6, and records survey data and the like. A recording medium 8, a display unit 9 for displaying survey data, a keyboard 10 as operation means, and the like.

[0004] In addition to the above, conventional surveying instruments include a servo mechanism (not shown) for electrically rotating the telescope 11 and a GPS receiver (not shown) capable of absolutely measuring the position where the surveying instrument is installed. Although there is a type in which is incorporated, the basic configuration as a surveying instrument is the same as that in the case of FIG.

[0005]

Since the conventional surveying instrument does not have means for recording image data, the actual surveying operation requires an image of the surveying target object along with the distance and angle to the surveying target object. Has photographed a recorded photograph of the survey target with a normal camera device or the like.

For this reason, when there are many surveying targets, a huge amount of work is required to correlate the survey data with the recorded photographs, which leads to an increase in cost and an inaccurate survey record due to an incorrect association. Had become.

[0007] Further, with the recent spread of digital still cameras, it has been attempted to centrally manage photographing data and survey data photographed by the digital still camera by a computer, but the digital data is not integrated with a surveying instrument. In the still camera, since the photographing action and the surveying action are performed separately, an error in association and the like could not be resolved.

On the other hand, as described in Japanese Patent Application Laid-Open No. 7-19874, it is conceivable to incorporate a mechanism equivalent to a digital still camera into a surveying instrument. First, image data is much larger than surveying data. Information volume, 2nd
In addition, since the number of shots required in the surveying work becomes extremely large with many survey points, for example, a recording device for simply integrating a surveying instrument and a digital still camera to record image data and the like Just sharing a medium results in a device that is not practical.

Further, when the surveying instrument and the digital still camera are simply integrated, in the surveying work, for example, when it is desired to photograph the situation where the surveying instrument itself is installed together with the background, or in a narrow place where the surveying instrument cannot be installed. It is not possible to cope with shooting in various situations, such as when shooting is desired.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a surveying instrument with an image pickup device which displays an image in the field of view of a telescope on an image display means of the camera device and can use the camera device alone if necessary. I do.

Further, according to the present invention, since the camera device is detachable, the camera device can be used alone, and image data including an image of the surveying instrument itself can be obtained. Further, according to the present invention, image data and
Alternatively, since the survey data can be transferred between the camera device and the surveying instrument, the recording means can be effectively used according to the data capacity.

Further, in the surveying instrument with an imaging device according to the present invention, the image data obtained by the first imaging device is displayed on the image display device of the camera device.

According to the present invention, since the image data obtained by the first image pickup means is displayed on the image display means of the camera device, there is no need to provide an image display means on the surveying instrument side.

Further, the surveying instrument with an imaging device according to the present invention is characterized in that the image data obtained by the first or the second imaging device is recorded in a recording device in the camera device.

According to the present invention, since image data requiring a large amount of storage area can be recorded in the recording means in the camera device, it is not necessary to increase the storage capacity of the recording means of the surveying instrument.

The object of the present invention is to measure a direction of the survey target in accordance with a direction of the telescope capturing the survey target and the telescope in a state where the survey target is captured, and to determine a distance to the survey target. A surveying instrument having surveying means for surveying, further comprising: an imaging means for photographing an image in the field of view of the telescope; an image processing means for processing image data acquired by the imaging means; And a magnification switching means for changing the magnification of the telescope in response to the result.

According to the present invention, since there is provided a magnification switching means for changing the magnification of the telescope in response to the result of the survey by the surveying means, the survey data and the low and high magnification image data can be obtained at one time. Work operability can be improved.

Further, in the surveying instrument with an image pickup device according to the present invention, the image processing means synthesizes the low magnification and high magnification image data obtained by the image pickup means.

According to the present invention, since the image processing means can combine the low-magnification and high-magnification image data obtained by the imaging means, it is clear which survey point of which survey target was measured. Thus, the usefulness of the survey record can be significantly improved.

Further, the magnification switching means of the surveying instrument with an imaging device according to the present invention switches from a low magnification to a high magnification when the distance measurement by the surveying means becomes possible.

According to the present invention, since the resolution of a less important portion of the image data can be reduced and recorded, the data amount of one image data is reduced, and the recording means can be effectively used. In addition, since the number of images that can be photographed is increased, it is possible to easily cope with photographing many survey points.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, such embodiments do not limit the technical scope of the present invention.

FIG. 1 is a configuration diagram of a surveying instrument with an imaging device according to an embodiment of the present invention. This surveying instrument with an imaging device
The surveying instrument 100 and the detachable camera device 300 are connected by signal connection mechanisms 32 and 33.

The surveying instrument 100 has a vertical axis 21 for rotating the telescope 20 in the horizontal direction and a horizontal axis 22 for rotating the telescope 20 in the vertical direction. It is configured to intersect at the rotation center 23.

An angle measuring mechanism 24 for detecting the horizontal rotation angle of the telescope 20 and an angle measuring mechanism 25 for detecting the vertical rotation angle are provided, and a part of the optical system is shared with the telescope 20. A distance measuring mechanism 26 is provided.

The surveying instrument 100 further includes an angle measuring mechanism 24,
A data processing unit 27 that processes the angle measurement data obtained by 25 and the distance measurement data obtained by the distance measurement mechanism 26, a recording medium 28 that records the data, a display unit 29 that displays survey data, a keyboard 30, and the like. Provided.

The surveying instrument 100 according to the embodiment of the present invention includes:
Further, optical systems 34 and 35 for capturing an image in the field of view of the telescope 20, a CCD for converting the formed image to an electric signal
, An image data processing mechanism 37 for converting an image signal output from the image sensor 36 into digital data
Is provided. Thus, the image data in the field of view of the telescope 20 can be recorded on the recording medium 28 together with the survey data. The variable magnification lens 38 and the motor mechanism 39 in the telescope 20 will be described later.

On the other hand, the camera device 300 is
Are detachably connected by signal connection mechanisms 32 and 33, and an imaging optical system 310 such as an objective lens and an imaging element 311 such as a CCD are provided. In the camera device 300,
Further, a photographing data processing unit 312 for controlling the entire camera device 300, a display unit 313 such as a liquid crystal display for displaying a photographed image, a keyboard 314, a recording medium 315 for recording photographing data, and the like are provided.

As described above, since the camera device 300 has all the components as a normal digital still camera, it can be operated independently by disconnecting the signal connection mechanisms 32 and 33. For this reason, in the camera device 300, when the operation starts, the communication connection mechanisms 32, 33
A process of examining the situation and selecting an operation mode is performed.

Next, a processing flowchart when the operation of the camera device 300 according to the present embodiment starts will be described with reference to FIG. When the operation is started by turning on the power or the like, the camera device 300 transmits a response request signal to the data processing unit 27 of the surveying instrument 100 via the signal connection mechanisms 32 and 33 (S1).

The photographing data processing unit 312 determines whether or not there is a response from the data processing unit 27 (S2). If there is a response, that is, if the camera device 300 is connected to the surveying instrument 100, The apparatus 300 is set to the main body interlock mode (S3).

In the main body interlocking mode, image data photographed by the surveying instrument 100 is displayed on the display unit 313 of the camera device 300, and image data photographed by the camera device 300 is displayed on the recording medium 28 of the surveying instrument 100 or the camera device 300. It is stored in a recording medium that can be arbitrarily specified among the recording media 315. Further, in the main body interlocking mode, as described later in detail, it is easy to record image data and survey data in association with each other.

On the other hand, when there is no response from the data processing unit 27, that is, when the camera device 300 is not connected to the surveying instrument 100, the camera device 300 is set to the single mode (S4). In the single mode, the camera device 300 operates as a single camera device, and the captured image data is
It is stored in the built-in recording medium 315.

Even when the camera device 300 is operated alone, the camera device 300 is moved to the surveying instrument 10 after the independent operation.
0, the camera device 300 based on time data, etc.
Can be associated with the survey data acquired by the surveying instrument 100. After the camera device 300 is set to the main body interlock mode or the single mode, the process returns to the normal process as the camera device 300 (S5).

In the above, the camera device 300 and the surveying instrument 10
Although the case where 0 is detachable has been described, it is needless to say that a configuration in which the camera device 300 and the surveying instrument 100 are fixedly connected is also possible.

By the way, the camera device 300 and the surveying instrument 10
In a state where 0 is connected, data is recorded at two locations: the recording medium 28 of the surveying instrument main body 100 and the recording medium 315 of the camera device 300. On the other hand, the amount of stored data differs between the image data and the survey data, and the situation in which the data is used after the completion of the survey work is also different.

For this reason, in the initial setting of the surveying instrument 100, etc.,
By designating which recording medium to store those data, the recording medium and the data can be effectively used.
That is, data to be stored include (1) distance measurement, angle measurement,
Surveyor-specific data such as coordinate data and work notes,
(2) There are data specific to the camera device, such as image data and shooting memos. On the other hand, storage locations are (a) only the recording medium 28 of the surveying instrument, (b) only the recording medium 315 of the camera device, and (c). There are both the recording medium 28 of the surveying instrument and the recording medium 315 of the camera device, and (d) a combination of one or both of the recording medium 28 of the surveying instrument and the recording medium 315 of the camera device depending on the type of data. Therefore, if the storage location is selected according to the type of data to be stored and the form of use, the recording medium and the data can be effectively used.

On the other hand, since the telescope 20 of the surveying instrument 100 has a relatively high magnification, the image in the field of view of the telescope 20 is limited to only the image near the survey target. However, the information to be left as image data in the surveying work often includes the surroundings of the survey target as well as the surroundings.

Therefore, the surveying instrument 1 according to the embodiment of the present invention
00 is provided with a variable magnification lens 38 and a motor mechanism 39,
For example, the magnification of the telescope 20 is made variable by outputting a drive signal from the data processing unit 27 to the motor mechanism 39.

In this case, first, the telescope 20 is set at a low magnification to capture a wide-angle image in which the entire image of the survey target is understood, and then the telescope 20 is switched to a high magnification, and the high-magnification image in which an accurate survey point is known is again obtained. It is possible to capture. Further, the wide-angle image and the high-magnification image can be synthesized by image processing as described later, and the usefulness as survey recording can be significantly improved.

FIG. 3 is a flowchart in the case where a wide-angle image and a high-magnification image are combined and displayed in the embodiment of the present invention, and FIG. 4 is an image example in that case. This will be described with reference to FIG. 4 according to FIG. When the power of the surveying instrument 100 is turned on and the operation is started, the data processing unit 27 outputs a drive signal to the motor mechanism 39 to set the telescope 20 to a low magnification (S11). If the telescope 20 has a low magnification, the surveyor can easily search for the survey target.

Next, the distance is measured by making the direction of the telescope 20 coincide with the survey target, and low-magnification image data is acquired in order to record the entire image of the survey target (S12).
FIG. 4A shows a wide-angle image 40 obtained at a low magnification.

The acquired low-magnification image data is stored in the recording medium 2.
When stored in 8 or the like, the data processing unit 27 outputs a drive signal to the motor mechanism 39 to set the telescope 20 to a high magnification (S13). In the high magnification state, the telescope 20 can be accurately pointed to the survey point of the survey target, so that accurate distance measurement and angle measurement can be performed, and image data in the high magnification state can be accurately recorded as a survey record of the survey point. Is acquired (S14). FIG. 4B shows a high magnification image 41 obtained at a high magnification.

Next, the image data is reduced (S1).
5). That is, since only the central portion of the image, which is the survey point of the survey target, is required in the high-magnification image data, the data of the peripheral portion of the image is deleted. Thereby, it is possible to save the storage area of the recording medium. Central partial image 4 cut out from high magnification image 41
2 is shown in FIG.

Next, the high-magnification image data and the low-magnification image data are combined (S16). Since the high-magnification image data is reduced to the center of the survey target,
It is often difficult to understand which survey target was surveyed. For this reason, the usefulness as a survey record is improved by combining the entire survey target with low-magnification image data captured together with the surrounding situation. The synthesized image 43 is shown in FIG.

The data of the synthesized image is recorded on the recording medium 28 or the like (S17). If the image 43 in which the wide-angle image and the high-magnification image are combined is recorded in this manner, it is very convenient for later inspection of survey points and the like.

As described above, when recording image data in surveying or measurement, it is necessary to switch the magnification of the telescope 20, but it is very complicated to manually switch the magnification every time image data is recorded. Therefore, according to the surveying instrument 100 of the embodiment of the present invention, when the distance can be measured by the distance measuring mechanism 26, it is possible to automatically change the magnification and to simplify the operation.

FIG. 5 shows a surveying instrument 10 according to an embodiment of the present invention.
It is a flowchart at the time of switching the magnification of the telescope 20 automatically at 0. When the survey starts,
The magnification of the telescope 20 is set to a low magnification to make it easier to find the survey target (S21).

The distance measuring mechanism 26 starts operating (S22),
It waits in a state where it can receive the ranging signal reflected by the survey target (S23). If the survey target is captured near the center of the field of view in this state, it is confirmed that the distance can be measured by receiving the distance measurement signal.

In this state, the distance is measured, and the low-magnification image data is temporarily stored (S24). Then, in response to the reception of the ranging signal, the magnification of the telescope 20 is automatically switched to the high magnification (S25), and the apparatus stands by in a state in which confirmation as to whether or not to record the low magnification image data is received (S26, S2).
7).

At this time, if the survey points are correct, the temporarily stored low-magnification image data and high-magnification image data are recorded (S28), and the process returns to (S26). On the other hand, if it is not the correct survey point, search for the correct survey point with high magnification and shoot and record,
A confirmation of processing for changing to a low magnification is received (S29).
If the correct survey point is photographed and recorded with the high magnification, the process returns to the reception of the process (S26), and if it is changed to the low magnification, the process returns to the step S21. Even if the survey target is outside the high magnification field of view, a correct distance measurement value can be obtained if it is within a predetermined range of the low magnification field center.

In this way, the magnification of the telescope 20 can be automatically switched, and the image data obtained at each magnification is synthesized and recorded as described above.
Further, image data can be obtained and recorded more efficiently.

By the way, a large-capacity storage area is required to record image data. However, in order to save the storage area, it is desirable to store the image data in a minimum necessary amount. The image data required for surveying is often concentrated at the center of the survey target when the telescope 20 collimates the survey target, so that there is often no problem even if the information amount in the peripheral portion is reduced. .

FIG. 6 shows an image 5 obtained by the telescope 20.
This is a specific example in which 0 is divided into a plurality of regions. A case will be described in which the peripheral portion is divided into regions 1 to 4 and the central portion is divided as region 5 to reduce the information amount of peripheral regions 1 to 4.

For example, consider the case where only the area 5 in FIG. 6 is recorded as a full-color image and the areas 1 to 4 are recorded as a monochrome image. Assuming that the storage capacity required for one pixel is 3 bytes for a full-color image and 1 byte for a monochrome image, in this case, the storage area is about one-third that of the case where the entire area is composed of a full-color image. Will be done.

FIG. 7 shows an example of the structure of image data in which areas 1 to 4 in FIG. 6 are monochrome images and area 5 is a full-color image. The left side of FIG. 7 shows the contents of data stored in the respective storage areas. The right side shows a specific example of data.

First, the storage area 70 indicates that the entire image is divided into five areas, and the storage area 71 first indicates that the data of the area 1 is stored. Further, the upper left coordinates of the area 1 in the storage area 72, for example, (0,
0), and the lower right coordinate of the area 1 in the storage area 73, for example, (399, 119). The storage area 74 stores the number of bytes per pixel. When this number is 1, it indicates that the area 1 is a monochrome pixel.

All the pixel data of the area 1 are stored in the storage areas 75 to 78, and a check sum for confirmation is stored in the storage area 79, and the image data of the area 1 is completed. Storage area 80 ~
Reference numeral 94 stores image data relating to the areas 2 to 5 as in the case of the area 1, and the end of the entire area is indicated in the storage area 95 to complete the entire image data. However, since the area 5 is a full-color image and requires three bytes for one pixel, the number of bytes constituting one pixel of the storage area 89 is three.

On the other hand, it is also possible to reduce the pixel resolution of the peripheral portion of the image to reduce the recording capacity of the image data. FIG. 8 is an explanatory diagram of a method for reducing the pixel resolution of a peripheral portion of an image. As shown in FIG. 8, the pixels (1-4, 5-8, 9-12, etc.) in the peripheral portion
An operation of averaging pixel data to obtain one pixel data is performed to reduce the recording capacity.

FIG. 9 shows an example of the structure of image data when the pixel resolution of the areas 1 to 4 in FIG. 6 is reduced as the peripheral part of the image. The left side of FIG. 9 shows the contents of data stored in each storage area, and the right side shows a specific example of data. In this case, as a configuration of the image data, a storage area for storing pixel resolution data is added, and the number of pixels of the stored data per pixel in the actual image is specified. Thus, a data configuration with reduced storage capacity can be obtained.

That is, in FIG. 9, since the pixel resolution of the storage area 96 is L (for example, 4), it is shown that the data per pixel in the area 1 corresponds to four pixels. On the other hand, since the pixel resolution of the storage area 97 is H (for example, 1),
This indicates that the data per pixel in the area 5 corresponds to one pixel. Thus, the storage capacity of the recording medium can be reduced by reducing the pixel resolution of the peripheral portion of the image.

In the surveying instrument 100 according to the embodiment of the present invention,
Since both the survey data and the image data can be obtained by the data processing unit 27, when storing the data in the recording medium 28, the configuration of the data to be stored is designated, so that the recorded data can be effectively used. Can be achieved.

FIG. 10 shows an example of a configuration in which survey data and image data are recorded in association with each other. According to this configuration, the survey data such as the distance, the angle, the coordinates, and the survey memo and the image data correspond to the point numbers 200, 201, and 20 indicating the survey points.
Since the two are stored in a continuous storage area so as to be integrated with each other, the correspondence between the survey data and the image data becomes clear,
Convenience as a survey record is improved.

FIG. 11 shows an example of a configuration in which the survey data 210 and the image data 211 are stored as separate data files, and the data is associated with each other by link information. When data is stored in such a configuration, the correspondence between the survey data 210 and the image data 211 is clarified, search of each data is speeded up, and data can be used more flexibly. For example, when the image data 211 photographed at a certain place is classified according to the photographing place, it can be automatically performed using the coordinate data included in the survey data 210.

In the above embodiment, the angle measuring mechanism 24,
Although the surveying instrument having both the 25 and the distance measuring mechanism 26 has been described, the present invention relates to a level or theodolite.
For example, the present invention can be applied to a surveying instrument having only an angle measuring mechanism and not having a distance measuring mechanism. Also, it goes without saying that a similar system can be configured even when the camera device 300 is a digital video camera or the like that can record moving images.

[0071]

As described above, according to the present invention, since the optical system for capturing an image in the field of view of the telescope and the imaging means are provided, image data of the survey target can be easily obtained. Further, since the camera device is detachable, the camera device can be used alone, and image data including an image of the surveying instrument itself can be obtained. Further, since the image data and / or the survey data can be transferred between the camera device and the surveying instrument, the recording means can be effectively used according to the data capacity.

Further, according to the present invention, since there is provided magnification switching means for changing the magnification of the telescope in response to the measurement result of the surveying means such as a distance measuring mechanism provided in the telescope, the survey data and the low and high magnifications are provided. Can be obtained at a time, and the operability of the surveying operation can be improved.

Further, according to the present invention, the image data obtained by the image pickup apparatus can be recorded with reduced resolution of the less important part, so that the data amount of one image data is reduced, and Effective use becomes possible. In addition, since the number of images that can be photographed is increased, it is possible to easily cope with photographing many survey points.
