Abstract
Description
本発明は、測量器の映像を拡大もしくは記録することで、測量器の機能を補助する測量器補助具に関する。 The present invention relates to a surveying instrument auxiliary tool that assists the functions of a surveying instrument by enlarging or recording an image of the surveying instrument.
従来、測量や土木水道工事の現場で建造物等の水平や高さを確認する際に使用される測量器はアナログ機器のため、その映像を残すことができないといった問題点があった。
測量器の映像をカメラで撮影できれば、測量器の映像を記録できるので、測量器の機能を補助することができる。
一方、望遠鏡の接眼レンズにカメラのレンズを接近させて、望遠鏡により拡大された被写体をカメラで撮影するコリメート法が知られている。
しかしながら、単に、望遠鏡の接眼レンズにカメラのレンズを押し付けるだけでは、接眼レンズの光軸とカメラのレンズの光軸とを一致させるのが容易でないだけでなく、撮影時に手振れを起こし易いので、正確な映像を撮影することができなかった。
そこで、接眼レンズの光軸とカメラのレンズの光軸とを一致させるように、カメラを保持するカメラ固定冶具が提案されている（例えば、特許文献１参照）。
このカメラ固定冶具は、望遠鏡にネジ穴を設け、このネジ穴にピン等で押さえ板を回転可能に取付けるとともに、撮影時には押さえ板をカメラ付携帯電話機のレンズ側の面に押付けることで、望遠鏡をカメラ付携帯電話のレンズ側の面に片手で固定できるので、望遠鏡の映像を容易に撮影することができる、とされている。
Conventionally, the surveying instruments used to check the level and height of buildings at surveying and civil engineering and waterworks sites are analog devices, which poses the problem of not being able to record images.
If images of surveying instruments can be captured with a camera, the images of the surveying instruments can be recorded, thereby assisting the functions of the surveying instruments.
On the other hand, a collimation method is known in which a camera lens is brought close to the eyepiece of a telescope, and the object magnified by the telescope is photographed with the camera.
However, simply pressing the camera lens onto the telescope's eyepiece does not make it easy to align the optical axis of the eyepiece and the camera lens, and also tends to cause camera shake when taking pictures, so it is difficult to accurately I wasn't able to take any good footage.
Therefore, a camera fixing jig has been proposed that holds the camera so that the optical axis of the eyepiece and the optical axis of the camera lens are aligned (for example, see Patent Document 1).
This camera fixing jig has a screw hole in the telescope, a holding plate is rotatably attached to the screw hole with a pin, etc., and the holding plate is pressed against the lens side of the camera phone when taking pictures. It is said that it can be fixed to the lens side of a camera-equipped cell phone with one hand, making it easy to take telescope images.
しかしながら、特許文献１のカメラ固定冶具は、望遠鏡が、カメラ付携帯電話機よりも小さくかつ軽量な小型望遠鏡に限られるだけでなく、撮影者が押さえ板を片手でカメラ付携帯電話機を押さえつけなければならないため、測量や土木水道工事の現場で用いられる測量器などの重量があり、かつ、高性能の望遠鏡に適用することは困難であった。
また、特許文献１のカメラ固定冶具は、押さえ板の一端を固定するためのネジ穴を設ける必要があるため、市販の望遠鏡や測量器をそのまま用いることができない、といった問題点もあった。
However, in the camera fixing jig of Patent Document 1, the telescope is not only limited to a small telescope that is smaller and lighter than a camera-equipped mobile phone, but also requires the photographer to hold down the camera-equipped mobile phone with one hand on a holding plate. Therefore, it has been difficult to apply it to heavy, high-performance telescopes such as surveying instruments used at surveying and civil engineering and water works sites.
Furthermore, the camera fixing jig of Patent Document 1 requires a screw hole for fixing one end of the holding plate, so there is a problem that a commercially available telescope or surveying instrument cannot be used as is.
本発明は、従来の問題点に鑑みてなされたもので、形状や大きさが異なったカメラであっても、カメラのレンズを測量器の接眼レンズに接近させた状態で測量器にカメラを固定して測量器の映像を撮影できる測量器補助具を提供することを目的とする。 The present invention was made in view of the conventional problems, and even when cameras have different shapes and sizes, the camera is fixed to the surveying instrument with the camera lens close to the eyepiece of the surveying instrument. The purpose of the present invention is to provide a surveying instrument auxiliary tool that can take images of surveying instruments.
本発明は、カメラと、前記カメラを測量器の接眼レンズに前記カメラのレンズを対向させた状態で前記測量器に固定するカメラ固定冶具とを備えた測量器補助具であって、前記測量器の前記接眼レンズ側を前側、前記接眼レンズとは反対側を後側としたとき、前記カメラ固定冶具は、前記測量器の前記接眼レンズ側に取付けられて上下方向に延長する測量器側垂直板と、前記測量器側垂直板を前記測量器に取付ける取付板と、前記測量器側垂直板に対して上下方向及び左右方向に取付位置が変更可能に取付けられて上下方向に延長するカメラ側垂直板と、前記カメラ側垂直板の下端側から後側でかつ前記カメラ側垂直板の厚さ方向に垂直な方向に突出して前記カメラを搭載するカメラ搭載板と、を備え前記カメラは、前記カメラ搭載板に、前後方向に取付位置が変更可能に取付けられていることを特徴とする。
これにより、簡単な構成で、形状や大きさが異なったカメラであっても、カメラのレンズを測量器の接眼レンズに接近させた状態で測量器にカメラを容易に固定することができるので、測量器の映像を確実に撮影して記憶させることができる。また、カメラで撮影した画像は測量器の映像よりも倍率が高いので、対象物の水平や高さを精度よく測定できる。
また、前記カメラを、ディスプレイ及び通信手段を備えたカメラ付携帯電話に内蔵されたカメラとしたので、測量器の映像をカメラ付携帯電話機に記録することができるとともに、記録された画像を他の作業者などに送信して情報を共有することができる。
また、測量器の接眼レンズを通して１度に覗くことができるのは１人であったが、カメラ付携帯電話のディスプレイを介せば、測量器の映像が携帯電話のディスプレイに大きく映し出されるので、測量器の映像を１度に複数人に共有できる。
また、前記測量器の前記接眼レンズに前記カメラの対物レンズを押し付けた状態で前記カメラを固定することで、接眼レンズの光軸（中心軸）と対物レンズの光軸（中心軸）とを確実に一致させるようにしたので、対象物の水平や高さの測定精度が向上した。
また、前記カメラ搭載板に、前記カメラの高さを調整する高さ調整手段を設けたので、カメラのレンズの位置精度を向上させることができる。したがって、測定精度を更に向上させることができる。
The present invention provides a surveying instrument auxiliary tool comprising a camera and a camera fixing jig for fixing the camera to the surveying instrument with the lens of the camera facing the eyepiece of the surveying instrument. When the eyepiece side of the instrument is the front side and the side opposite to the eyepiece lens is the rear side, the camera fixing jig is a surveying instrument side vertical plate that is attached to the eyepiece side of the surveying instrument and extends in the vertical direction. a mounting plate for attaching the surveying instrument side vertical plate to the surveying instrument; and a camera side vertical plate that is attached to the surveying instrument side vertical plate so that its mounting position can be changed in the vertical and horizontal directions and that extends in the vertical direction. and a camera mounting plate on which the camera is mounted, protruding rearward from the lower end of the camera-side vertical plate and in a direction perpendicular to the thickness direction of the camera-side vertical plate. It is characterized in that it is attached to the mounting plate so that its attachment position can be changed in the front-rear direction.
This makes it possible to easily fix the camera to the surveying instrument with a simple configuration, even if the camera has a different shape or size, with the camera lens close to the eyepiece of the surveying instrument. To reliably capture and store images of surveying instruments. Additionally, images taken with a camera have a higher magnification than images taken by a surveying instrument, so the horizontality and height of an object can be measured with high precision.
Moreover, since the camera is a camera built into a camera-equipped mobile phone equipped with a display and a communication means, it is possible to record the image of the surveying instrument on the camera-equipped mobile phone, and the recorded images can be shared with others. You can share information by sending it to workers.
Also, only one person could look through the eyepiece of a surveying instrument at a time, but if you use a camera-equipped mobile phone display, the image of the surveying instrument will be projected large on the mobile phone display. You can share the image of the surveying instrument with multiple people at once.
Furthermore, by fixing the camera with the objective lens of the camera pressed against the eyepiece of the surveying instrument, the optical axis (center axis) of the eyepiece and the optical axis (center axis) of the objective lens are ensured. The accuracy of measuring the horizontal and height of objects has improved.
Further, since the camera mounting plate is provided with a height adjusting means for adjusting the height of the camera, the positional accuracy of the camera lens can be improved. Therefore, measurement accuracy can be further improved.

The camera-equipped mobile phone 2 is fixed to the camera fixing jig 3 so that the optical axis of the built-in camera lens (hereinafter referred to as camera lens L2) is in the front-back direction.
図２（ａ），（ｂ）にも示すように、カメラ固定冶具３は、測量器側垂直板３１と、取付板３２と、カメラ側垂直板３３と、カメラ搭載板３４と、カメラ支持部材３５とを備え、カメラ付携帯電話機２を、カメラ付携帯電話機２のカメラレンズ収納部２１に収納されたカメラレンズＬ２が測量器１の接眼レンズＬ１に対向する状態で測量器１に固定する。
測量器側垂直板３１は、測量器１の下方で、接眼レンズＬ１の位置よりも前方に配置された上下方向に延長する板面の形状が矩形の板材で、中央部には上下方向に延長して上方に開口する切り欠き部３１ｋが形成されている。
取付板３２は、測量器側垂直板３１の下端部から前方に延長する平面視矩形の板材で、正三角形状に配置された３個の貫通孔３２ｋが形成されている。貫通孔３２ｋには整準ネジ１２ａが挿入され、取付板３２は整準台１２の調整ツマミ１２ｂ上に搭載される。
カメラ側垂直板３３は、測量器側垂直板３１の後側の面である裏面側に取付けられて上下方向に延長する板面の形状が矩形の板材で、中央部には左右方向に延長する左右案内窓３３ｋが形成されている。
As shown in FIGS. 2(a) and 2(b), the camera fixing jig 3 includes a surveying instrument side vertical plate 31, a mounting plate 32, a camera side vertical plate 33, a camera mounting plate 34, and a camera support member. 35, and the camera-equipped mobile phone 2 is fixed to the surveying instrument 1 in a state in which a camera lens L2 stored in a camera lens storage part 21 of the camera-equipped mobile phone 2 faces an eyepiece L1 of the surveying instrument 1.
The surveying instrument side vertical plate 31 is a plate material with a rectangular plate surface that extends in the vertical direction and is located below the surveying instrument 1 and in front of the position of the eyepiece L1. A notch 31k is formed which opens upward.
The mounting plate 32 is a rectangular plate member extending forward from the lower end of the survey instrument side vertical plate 31 in a plan view, and has three through holes 32k arranged in an equilateral triangle shape. The leveling screw 12a is inserted into the through hole 32k, and the mounting plate 32 is mounted on the adjustment knob 12b of the leveling stand 12.
The camera-side vertical plate 33 is a rectangular plate attached to the rear surface of the survey instrument-side vertical plate 31 and extends in the vertical direction. Left and right guide windows 33k are formed.
カメラ側垂直板３３は、測量器側垂直板３１に上下方向及び左右方向に取付位置が変更可能に取付けられる。具体的には、測量器側垂直板３１の切り欠き部３１ｋとカメラ側垂直板３３の左右案内窓３３ｋとが交差する位置の空間（以下、垂直板固定箇所という）に測量器側垂直板３１の前側から、前後方向に延長するボルト３１ａを挿し込み、このボルト３１ａを左右案内窓３３ｋの後側にて、ナット３１ｂで締結することにより、カメラ側垂直板３３を測量器側垂直板３１に固定する。
測量器側垂直板３１は取付板３２を介して測量器１に固定されているので、カメラ側垂直板３３を上下方向及び左右方向に動かし、カメラ付携帯電話機２のカメラレンズＬ２が測量器１の接眼レンズＬ１に対向する位置になるように垂直板固定箇所を決定する。
カメラ搭載板３４は、カメラ側垂直板３３の下端側から後側でかつ前記カメラ側垂直板３３の厚さ方向に垂直な方向に突出する平面視矩形の板材で、中央部には前後方向に延長する前後案内窓３４ｋが形成されている。カメラ付携帯電話機２は、カメラ支持部材３５を介してカメラ搭載板３４に取付けられる。
The camera-side vertical plate 33 is attached to the surveying instrument-side vertical plate 31 so that its mounting position can be changed in the vertical and horizontal directions. Specifically, the surveying instrument side vertical plate 31 is placed in the space where the notch 31k of the surveying instrument side vertical plate 31 intersects the left and right guide windows 33k of the camera side vertical plate 33 (hereinafter referred to as the vertical plate fixing location). Insert a bolt 31a extending in the front-rear direction from the front side of the camera, and tighten this bolt 31a with a nut 31b behind the left and right guide window 33k to connect the camera-side vertical plate 33 to the surveying instrument-side vertical plate 31. Fix it.
Since the surveying instrument side vertical plate 31 is fixed to the surveying instrument 1 via the mounting plate 32, by moving the camera side vertical plate 33 vertically and horizontally, the camera lens L2 of the camera-equipped mobile phone 2 is fixed to the surveying instrument 1. The vertical plate fixing location is determined so as to face the eyepiece L1.
The camera mounting plate 34 is a rectangular plate member in a plan view that protrudes rearward from the lower end of the camera side vertical plate 33 and in a direction perpendicular to the thickness direction of the camera side vertical plate 33. An extending front and rear guide window 34k is formed. The camera-equipped mobile phone 2 is attached to a camera mounting plate 34 via a camera support member 35.
カメラ支持部材３５はカメラ把持具３５ａと、支持棒３５ｂと、固定具としての上ナット３５ｃ、下ナット３５ｄとを備え、カメラは、前記カメラ搭載板３４に、前後方向に取付位置が変更可能に取付けられている。
カメラ把持具３５ａとしては、例えば、図２（ａ）の右上の図に示すように、カメラ付携帯電話機２を幅方向上側から押さえる上側押さえ部材３５１と、上側押さえ部材３５１幅方向下側から押さえる下側押さえ部材３５２とを備え、上側押さえ部材３５１が下側押さえ部材３５２に上下にスライド可能に取付けられている構成の周知のカメラ把持具が用いられる。
カメラ付携帯電話機２は、上側押さえ部材３５１と下側押さえ部材３５２との間に幅方向両側から、カメラレンズＬ２側を前側にし、長さ方向が左右方向になるように把持される。下側押さえ部材３５２は下側で支持棒３５ｂの上端部に固定されている。
カメラ把持具３５ａの幅寸法は、カメラレンズＬ２がカメラ把持具３５ａの外側（左側）に位置するように、カメラ付携帯電話機２の長さ寸法の半分程度である。
なお、スライド機構としては、例えば、上側押さえ部材３５１に幅方向両端部に下方に延長するレール部３５３を設け、このレール部３５３の内側に下側押さえ部材３５２のスライド部３５４を配置するとともに、レール部３５３とスライド部３５４とをボールネジ３５５で連結する構成とすればよい。これにより、ボールネジ３５５の螺入深さを変更することで、上側押さえ部材３５１と下側押さえ部材３５２との間隔を調整できるので、幅の異なるカメラ付携帯電話機２についても把持することができる。
The camera support member 35 includes a camera gripping tool 35a, a support rod 35b, and an upper nut 35c and a lower nut 35d as fixing devices, and the mounting position of the camera can be changed in the front-rear direction on the camera mounting plate 34. installed.
As shown in the upper right diagram of FIG. 2A, the camera gripping tool 35a includes, for example, an upper pressing member 351 that holds the camera-equipped mobile phone 2 from above in the width direction, and an upper holding member 351 that holds the camera-equipped mobile phone 2 from below in the width direction. A well-known camera gripping tool is used, which includes a lower pressing member 352, and an upper pressing member 351 is attached to the lower pressing member 352 so as to be slidable up and down.
The camera-equipped mobile phone 2 is held between the upper holding member 351 and the lower holding member 352 from both sides in the width direction, with the camera lens L2 side facing forward and the length direction being the left and right direction. The lower pressing member 352 is fixed to the upper end of the support rod 35b on the lower side.
The width dimension of the camera gripping tool 35a is about half the length dimension of the camera-equipped mobile phone 2 so that the camera lens L2 is located on the outside (left side) of the camera gripping tool 35a.
In addition, as for the sliding mechanism, for example, the upper holding member 351 is provided with a rail portion 353 extending downward at both ends in the width direction, and the sliding portion 354 of the lower holding member 352 is arranged inside the rail portion 353. The rail portion 353 and the slide portion 354 may be connected by a ball screw 355. Thereby, by changing the threading depth of the ball screw 355, the distance between the upper pressing member 351 and the lower pressing member 352 can be adjusted, so that camera-equipped mobile phones 2 of different widths can be gripped.
支持棒３５ｂは表面にネジが形成された、いわゆるネジ棒で、上部はカメラ把持具３５ａの下側押さえ部材３５２に設けられた図示しないネジ穴に取付けられ、下部はカメラ搭載板３４に取付けられる。すなわち、支持棒３５ｂ下端を前後案内窓３４ｋよりも下方に突出させ、カメラ搭載板３４に形成された前後案内窓３４ｋの上側と下側とから、上下のナット３５ｃ，３５ｄを用いてカメラ搭載板３４に固定する。支持棒３５ｂの固定位置を前後方向に調整することで、カメラ付携帯電話機２を前後方向に移動させることができる。
すなわち、カメラ付携帯電話機２をカメラ搭載板３４に前後方向に取付位置が変更可能に取付けることができる。
また、上下のナット３５ｃ，３５ｄの高さ方向の取付位置（支持棒３５ｂのカメラ搭載板３４の上面から測った長さ）を変更することで、カメラ付携帯電話機２の高さを調整することができる。
The support rod 35b is a so-called threaded rod with a thread formed on its surface, and the upper part is attached to a screw hole (not shown) provided in the lower holding member 352 of the camera grip 35a, and the lower part is attached to the camera mounting plate 34. . That is, the lower end of the support rod 35b is made to protrude below the front and rear guide windows 34k, and the camera mounting board is inserted from the upper and lower sides of the front and rear guide windows 34k formed in the camera mounting board 34 using the upper and lower nuts 35c and 35d. Fixed at 34. By adjusting the fixed position of the support rod 35b in the front-back direction, the camera-equipped mobile phone 2 can be moved in the front-back direction.
That is, the camera-equipped mobile phone 2 can be attached to the camera mounting plate 34 so that the attachment position can be changed in the front-rear direction.
Furthermore, the height of the camera-equipped mobile phone 2 can be adjusted by changing the mounting positions of the upper and lower nuts 35c and 35d in the height direction (the length measured from the top surface of the camera mounting plate 34 of the support rod 35b). I can do it.
次に、カメラ付携帯電話機２の位置調整方法の一例を示す。
まず、カメラ付携帯電話機２をカメラ支持部材３５に取付ける。このとき、図３（ａ），（ｂ）に示すように、支持棒３５ｂを前方に移動させてカメラ付携帯電話機２を測量器１に予め接近させておく。
次に、カメラ側垂直板３３の位置を測量器側垂直板３１の上下方向（（ｂ）図）及び左右方向（（ａ）図）に動かして、カメラレンズＬ２の中心(光軸）とを一致させる。
最後に、支持棒３５ｂを前方に移動させてカメラレンズＬ２を測量器１の接眼レンズＬ１に押し付けた状態でカメラ付携帯電話機２の位置を固定する。
このとき、カメラ支持部材３５の支持棒３５ｂのカメラ搭載板３４の上面から測った長さを変更してカメラレンズＬ２の高さを微調整した後にカメラレンズＬ２を測量器１の接眼レンズＬ１に押し付けるようにすれば、測量器１の接眼レンズＬ１の光軸（中心軸）とカメラ付携帯電話機２のカメラレンズＬ２の光軸（中心軸）とを確実に一致させた状態とすることができる。
なお、実際には、測量器１の接眼レンズ収納部１４の内径は、カメラ付携帯電話機２のカメラレンズ収納部２１の外径よりも大きく、かつ、接眼レンズＬ１の外側に接眼レンズＬ１に近接して設けられた透明な保護板１４ｎは接眼レンズ収納部１４の後端よりも測量器１の内部側にあるので、上記の「カメラレンズＬ２を接眼レンズＬ１に押し付ける」とは、カメラレンズＬ２の保護ケースであるレンズ収納部２１の蓋部２１ｎを接眼レンズＬ１の保護板１４ｎに密着させることをいう。
なお、カメラ付携帯電話機２はカメラレンズＬ２側とは反対側がディスプレイ２２となっているので、測量器１の接眼レンズＬ１の光軸とカメラ付携帯電話機２のカメラレンズＬ２の光軸とが一致していることは、図１（ｂ）の右下図に示すように、ディスプレイ２２に映し出された測量器１の基準線（十字形の図形）が画面の中央に位置していることで確認できる。
これにより、測量器１の映像を高倍率で見ることができるとともに、カメラ付携帯電話機２で撮影した測量器１の映像を画像としてカメラ付携帯電話機２に記録することができる。また、記録された画像を他の作業者などに送信して情報を共有することも可能となる。
また、測量器の接眼レンズを通して１度に覗くことができるのは１人だが、カメラ付携帯電話を介せば測量器の映像を携帯電話のディスプレイに大きく映し出されるので、測量器の映像を１度に複数人に共有できる。
Next, an example of a method for adjusting the position of the camera-equipped mobile phone 2 will be described.
First, the camera-equipped mobile phone 2 is attached to the camera support member 35. At this time, as shown in FIGS. 3A and 3B, the support rod 35b is moved forward to bring the camera-equipped mobile phone 2 close to the surveying instrument 1 in advance.
Next, move the camera side vertical plate 33 in the vertical direction ((b) figure) and left/right direction ((a) figure) of the survey instrument side vertical plate 31 to align it with the center (optical axis) of the camera lens L2. Match.
Finally, the support rod 35b is moved forward to fix the position of the camera-equipped mobile phone 2 while pressing the camera lens L2 against the eyepiece L1 of the surveying instrument 1.
At this time, after finely adjusting the height of the camera lens L2 by changing the length of the support rod 35b of the camera support member 35 measured from the top surface of the camera mounting plate 34, the camera lens L2 is attached to the eyepiece L1 of the surveying instrument 1. By pressing, it is possible to ensure that the optical axis (center axis) of the eyepiece L1 of the surveying instrument 1 and the optical axis (center axis) of the camera lens L2 of the camera-equipped mobile phone 2 are aligned. .
Note that, in reality, the inner diameter of the eyepiece accommodating part 14 of the surveying instrument 1 is larger than the outer diameter of the camera lens accommodating part 21 of the camera-equipped mobile phone 2, and the inner diameter of the eyepiece accommodating part 14 of the surveying instrument 1 is larger than the outer diameter of the camera lens accommodating part 21 of the camera-equipped mobile phone 2. Since the transparent protective plate 14n provided as shown in FIG. This refers to bringing the lid 21n of the lens storage section 21, which is a protective case, into close contact with the protective plate 14n of the eyepiece L1.
In addition, since the camera-equipped mobile phone 2 has the display 22 on the side opposite to the camera lens L2 side, the optical axis of the eyepiece L1 of the surveying instrument 1 and the optical axis of the camera lens L2 of the camera-equipped mobile phone 2 are aligned. This can be confirmed by the fact that the reference line (cross-shaped figure) of the surveying instrument 1 shown on the display 22 is located in the center of the screen, as shown in the lower right figure of Figure 1(b). .
Thereby, the image of the surveying instrument 1 can be viewed at high magnification, and the image of the surveying instrument 1 taken by the camera-equipped mobile phone 2 can be recorded as an image on the camera-equipped mobile phone 2. It is also possible to share information by transmitting recorded images to other workers.
In addition, only one person can look through the eyepiece of a surveying instrument at a time, but if you use a camera-equipped mobile phone, the image of the surveying instrument will be displayed in a large size on the mobile phone's display. Can be shared with multiple people at once.
以上、本発明を実施の形態を用いて説明したが、本発明の技術的範囲は前記実施の形態に記載の範囲には限定されない。前記実施の形態に、多様な変更または改良を加えることが可能であることが当業者にも明らかである。そのような変更または改良を加えた形態も本発明の技術的範囲に含まれ得ることが、特許請求の範囲から明らかである。 Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the embodiments. It will be apparent to those skilled in the art that various changes or improvements can be made to the embodiments described above. It is clear from the claims that forms with such changes or improvements may also be included within the technical scope of the present invention.
例えば、前記実施の形態では、カメラとしてカメラ付携帯電話機２のカメラを用いたが、デジカメなど他のカメラを用いてもよい。なお、この場合には、カメラ把持具３５ａを別途準備する必要がある。
また、前記実施の形態では、取付板３２を測量器１の整準台１２に取付けたが、測量器本体１１に取付けてもよい。要は、測量器側垂直板３１が測量器本体１１の下側で接眼レンズＬ１の前側に垂直に保持されるように取付られていればよい。
また、前記実施の形態では、取付板３２に、測量器１の整準ネジ１２ａに対応する位置に正三角形状に配置された３個の貫通孔３２ｋを形成したが、貫通孔３２ｋを図４（ａ）に示すような、１個の貫通孔３２ｋと、前後方向に延長する案内窓３２Ｌと、貫通孔３２ｋの中心点と案内窓３２Ｌ内の点とで異なる大きさの正三角形を構成する点の軌跡である曲線状の案内窓３２Ｍとを設けるようにすれば、測量器１とは異なる大きさの測量器に用いることができる。あるいは、図４（ｂ）に示すような、正三角形の中心を通り、互いの角度が１２０度である３つの直線状の案内窓３２Ｎを設けてもよい。
For example, in the embodiment described above, the camera of the camera-equipped mobile phone 2 is used as the camera, but other cameras such as a digital camera may be used. Note that in this case, it is necessary to separately prepare the camera gripping tool 35a.
Further, in the embodiment described above, the mounting plate 32 is attached to the leveling base 12 of the surveying instrument 1, but it may be attached to the surveying instrument main body 11. In short, it is sufficient that the surveying instrument side vertical plate 31 is attached so as to be held vertically in front of the eyepiece L1 on the lower side of the surveying instrument main body 11.
Further, in the embodiment described above, three through holes 32k arranged in an equilateral triangle shape were formed in the mounting plate 32 at positions corresponding to the leveling screws 12a of the surveying instrument 1. As shown in (a), one through hole 32k, a guide window 32L extending in the front-rear direction, and a center point of the through hole 32k and a point inside the guide window 32L form an equilateral triangle with different sizes. If a curved guide window 32M, which is a locus of points, is provided, it can be used for a surveying instrument of a different size from the surveying instrument 1. Alternatively, as shown in FIG. 4(b), three linear guide windows 32N passing through the center of an equilateral triangle and forming an angle of 120 degrees with each other may be provided.
