　図１及び図２に示すように、本発明の車室内カメラ装置は、車両２の室内を撮影するカメラ１０と、制御部としてのコントローラ３と、を備える。カメラ１０は、車室内を撮影する撮像部１１を内蔵し、フレキシブルアーム１２の先端側１２ａに設置されている。フレキシブルアーム１２の基端側１２ｂは、車両２の運転席２５側における中央ピラー２７の上部に固定されている。 [First Embodiment]
As shown in FIGS. 1 and 2, the vehicle interior camera device of the present invention includes a camera 10 that captures an interior of a vehicle 2 and a controller 3 as a control unit. The camera 10 incorporates an imaging unit 11 that captures the interior of the vehicle and is installed on the distal end side 12 a of the flexible arm 12. A base end side 12 b of the flexible arm 12 is fixed to an upper portion of the central pillar 27 on the driver seat 25 side of the vehicle 2.
　カメラ１０の撮像部１１で撮影された撮影画像は、コントローラ３を介して表示部４に表示される。すなわち、コントローラ３は、撮像部１１で撮影された撮影画像を表示部４に表示するための処理を行う。表示部４は、運転席２５や助手席等から視認可能な位置に配置されるものであり、例えば、車両２に搭載されたモニタ（コンソールボックス内に設置されるナビゲーションシステムの表示画面等）である他、携帯端末の表示画面等であってもよい。ここで、携帯端末とは携帯電話を含む。 The captured image captured by the imaging unit 11 of the camera 10 is displayed on the display unit 4 via the controller 3. That is, the controller 3 performs processing for displaying the captured image captured by the imaging unit 11 on the display unit 4. The display unit 4 is disposed at a position that is visible from the driver's seat 25, the passenger seat, and the like. For example, the display unit 4 is a monitor mounted on the vehicle 2 (such as a display screen of a navigation system installed in the console box). In addition, it may be a display screen of a mobile terminal. Here, the mobile terminal includes a mobile phone.
　先端側１２ａにカメラ１０を支持するフレキシブルアーム１２は、例えば金属や樹脂製の螺旋巻パイプ材や可撓性を有する樹脂材料等で構成されている。カメラ１０は、他物に干渉した際に衝撃を吸収するために弾性を有する樹脂材料等で外装されており、全体に丸みを帯びた形状としてある。ユーザがカメラ１０またはフレキシブルアーム１２を手動で操作することにより、カメラ１０の位置を変更することができる。フレキシブルアーム１２はユーザの操作力が作用しなくなると、その位置でカメラ１０を保持するよう構成されている。 The flexible arm 12 that supports the camera 10 on the front end side 12a is made of, for example, a spiral pipe material made of metal or resin, a flexible resin material, or the like. The camera 10 is covered with an elastic resin material or the like to absorb an impact when it interferes with another object, and has a rounded shape as a whole. When the user manually operates the camera 10 or the flexible arm 12, the position of the camera 10 can be changed. The flexible arm 12 is configured to hold the camera 10 at the position when the user's operating force stops working.
　このような車室内カメラ装置であれば、ユーザが運転席２５から自らの手でカメラ１０またはフレキシブルアーム１２を操作することで、カメラ１０の向きを自由に変更することが可能となる。その結果、例えば、ユーザが運転中に、後部座席２６に着座させた子供の様子を確認したい場合に、カメラ１０の撮像部１１の向きを後部座席２６の方向にするだけで、表示部４で後部座席２６の子供の様子を容易に確認することができる。 With such a vehicle interior camera device, the user can freely change the orientation of the camera 10 by operating the camera 10 or the flexible arm 12 with his / her hand from the driver seat 25. As a result, for example, when the user wants to check the state of the child seated on the rear seat 26 while driving, the display unit 4 can be configured by simply turning the imaging unit 11 of the camera 10 toward the rear seat 26. The state of the child in the rear seat 26 can be easily confirmed.
　カメラ１０の撮像部１１の向きを後部座席２６の方向にし、表示部４に表示される後部座席２６の乗員の様子を視認することで、後部座席２６の乗員とのコミュニケーション手段として利用することもできる。カメラ１０の撮像部１１を斜め前方に向けた場合には、運転中の車外の景色を表示部４で楽しむことや、その景色を表示部４に記録することも可能となる。 The direction of the imaging unit 11 of the camera 10 is set to the direction of the rear seat 26, and the state of the occupant of the rear seat 26 displayed on the display unit 4 is visually recognized, so that it can be used as a means of communication with the occupant of the rear seat 26 it can. When the imaging unit 11 of the camera 10 is directed obliquely forward, it is possible to enjoy the scenery outside the vehicle while driving on the display unit 4 and to record the scenery on the display unit 4.
　また、カメラ１０の撮像部１１をユーザ自身に向けた場合には、例えば自身の後姿の確認や、後ろ髪のセット直し等にも使用することが可能である。防犯対策として、車室内全体の撮影や、車室内の運転席２５周りの前方のみを撮影することも可能となる。 Further, when the image pickup unit 11 of the camera 10 is pointed toward the user himself, it can be used, for example, for confirming the rear view of the user 10 or resetting the back hair. As a crime prevention measure, it is possible to take a picture of the entire vehicle interior or only the front of the driver's seat 25 around the vehicle interior.
[第２実施形態]
　ユーザがカメラ１０の位置や向きを自由に変更できるので、撮像部１１の角度／方向がユーザの操作によって任意に決定される。携帯端末のように、表示部とカメラが一体となったものでは、傾いたカメラ映像をそのまま表示部に表示させても、操作者が携帯端末の姿勢を適宜修正するためユーザにとって違和感のない映像となる。しかし、車両２に搭載される表示部４のように、カメラ１０と表示部４とが別体であり、カメラ１０の姿勢を瞬時に修正し固定することが難しい場合には、表示部４に対して撮影画像だけが傾くこととなり非常に見づらい映像となる。 [Second Embodiment]
Since the user can freely change the position and orientation of the camera 10, the angle / direction of the imaging unit 11 is arbitrarily determined by the user's operation. In the case where the display unit and the camera are integrated like a portable terminal, even if the tilted camera image is displayed on the display unit as it is, the operator does not feel uncomfortable because the operator appropriately corrects the posture of the portable terminal. It becomes. However, like the display unit 4 mounted on the vehicle 2, when the camera 10 and the display unit 4 are separate and it is difficult to instantaneously correct and fix the posture of the camera 10, the display unit 4 On the other hand, only the photographed image is tilted, and the video is very difficult to see.
　そこで、このような不具合を解消するために、本実施形態では、図２に示すように、撮像部１１の姿勢を検出する撮像姿勢検出部１３として、カメラ１０に３軸の加速度センサを配置し、コントローラ３には、撮像部１１による撮影画像を回転補正する処理演算部Ａを設けてある。 Therefore, in order to eliminate such problems, in this embodiment, as shown in FIG. 2, a triaxial acceleration sensor is arranged in the camera 10 as the imaging posture detection unit 13 that detects the posture of the imaging unit 11. The controller 3 is provided with a processing calculation unit A that rotationally corrects an image captured by the imaging unit 11.
　加速度センサは、カメラ１０に加速度運動が加えられた時の移動加速度とその移動量、及び、その傾きを検出する。加速度センサに代えて、撮像姿勢検出部１３として、地磁気センサ、ジャイロセンサを用いることもできる。また、撮像姿勢検出部１３は、加速度センサ、地磁気センサ、ジャイロセンサ等を適宜組み合わせてもよい。 The acceleration sensor detects the movement acceleration when the acceleration motion is applied to the camera 10, the amount of movement, and the inclination thereof. Instead of the acceleration sensor, a geomagnetic sensor or a gyro sensor may be used as the imaging posture detection unit 13. The imaging posture detection unit 13 may appropriately combine an acceleration sensor, a geomagnetic sensor, a gyro sensor, and the like.
　処理演算部Ａでは、まず、撮像姿勢検出部１３の検出データに基づいてカメラ姿勢演算部３０で撮像部１１の姿勢が演算され、カメラ姿勢演算部３０の演算結果を受けて回転判定演算部３１で撮像部１１の回転が判定される。次に、映像取得部３３に入力された撮影画像と回転判定演算部３１の演算結果とを受けて、回転判定演算部３１において撮像部１１が回転状態と判定されると、映像回転処理部３４で回転判定演算部３１の演算結果に基づいて撮影画像の回転補正が行われる。その後、撮影画像または映像回転処理後の画像が送信部３９から表示部４に送信される。 In the processing calculation unit A, first, the posture of the imaging unit 11 is calculated by the camera posture calculation unit 30 based on the detection data of the imaging posture detection unit 13, and the rotation determination calculation unit 31 receives the calculation result of the camera posture calculation unit 30. Thus, the rotation of the imaging unit 11 is determined. Next, in response to the captured image input to the video acquisition unit 33 and the calculation result of the rotation determination calculation unit 31, when the rotation determination calculation unit 31 determines that the imaging unit 11 is in the rotation state, the video rotation processing unit 34. Thus, the rotation correction of the captured image is performed based on the calculation result of the rotation determination calculation unit 31. Thereafter, the captured image or the image after the video rotation process is transmitted from the transmission unit 39 to the display unit 4.
　こうして、図３に示すように、撮像部１１の姿勢が検出された際には、処理演算部Ａによって撮影画像である実画像が回転補正され、表示部４に表示される画像は、例えば常に傾きのない水平な画像となる。その結果、表示部４の画像を視認するユーザの違和感も少なくなる。 Thus, as shown in FIG. 3, when the orientation of the imaging unit 11 is detected, the processing calculation unit A rotationally corrects the actual image that is the captured image, and the image displayed on the display unit 4 is always, for example, It becomes a horizontal image without inclination. As a result, the uncomfortable feeling of the user who visually recognizes the image on the display unit 4 is reduced.
[第３実施形態]
　フレキシブルアーム１２によってカメラ１０は車両２の前後左右方向に加えて、上下方向にも移動できる。ただし、カメラ１０を動作させたときに車両２が傾斜状態であるような場合には、カメラ１０の姿勢に車両２の姿勢が重畳されるため、カメラ１０のみの姿勢を正確に把握できない場合がある。よって、カメラ１０の姿勢と車両２の姿勢とを区別するために、カメラ１０側（移動側）と車両２側（固定側）の相対位置の関係から撮像部１１の姿勢を判定すると回転判定の精度が向上する。そこで、本実施形態では、図４に示すように、カメラ１０側の撮像姿勢検出部１３に加えて、車両２側にも車両の姿勢を検出する車両姿勢検出部２０を設ける。 [Third embodiment]
The flexible arm 12 allows the camera 10 to move in the vertical direction in addition to the front-rear and left-right directions of the vehicle 2. However, when the vehicle 2 is in an inclined state when the camera 10 is operated, the posture of the vehicle 2 is superimposed on the posture of the camera 10, and thus the posture of only the camera 10 may not be accurately grasped. is there. Therefore, in order to distinguish between the posture of the camera 10 and the posture of the vehicle 2, if the posture of the imaging unit 11 is determined from the relationship between the relative positions of the camera 10 side (moving side) and the vehicle 2 side (fixed side), rotation determination is performed. Accuracy is improved. Therefore, in the present embodiment, as shown in FIG. 4, in addition to the imaging posture detection unit 13 on the camera 10 side, a vehicle posture detection unit 20 that detects the posture of the vehicle is also provided on the vehicle 2 side.
　撮像姿勢検出部１３、車両姿勢検出部２０には、共に前述の加速度センサを用いることができる。加速度センサに代えて、撮像姿勢検出部１３、車両姿勢検出部２０として、地磁気センサ、ジャイロセンサを用いることもできる。また、撮像姿勢検出部１３、車両姿勢検出部２０は、加速度センサ、地磁気センサ、ジャイロセンサ等を適宜組み合わせてもよい。 The above-described acceleration sensor can be used for both the imaging posture detection unit 13 and the vehicle posture detection unit 20. Instead of the acceleration sensor, a geomagnetic sensor or a gyro sensor may be used as the imaging posture detection unit 13 and the vehicle posture detection unit 20. The imaging posture detection unit 13 and the vehicle posture detection unit 20 may be appropriately combined with an acceleration sensor, a geomagnetic sensor, a gyro sensor, and the like.
　コントローラ３の処理演算部Ａでは、まず、撮像姿勢検出部１３の検出データに基づいてカメラ姿勢演算部３０で撮像部１１の姿勢が演算され、一方、車両姿勢検出部２０の検出データに基づいて車両姿勢演算部３２で車両２の姿勢が演算される。次に、カメラ姿勢演算部３０及び車両姿勢演算部３２の演算結果を受けて、回転判定演算部３１で撮像部１１の回転が判定される。この回転は、車両２の姿勢を相殺したものであり、車両２に対するカメラ１０の姿勢変化を表すものである。次に、映像取得部３３に入力された撮影画像と回転判定演算部３１の演算結果とを受けて、回転判定演算部３１において撮像部１１が回転状態と判定されると、映像回転処理部３４においてカメラ姿勢演算部３０の演算結果に基づいて撮影画像の映像回転処理が行われる。その後、撮影画像または映像回転処理後の画像が送信部３９から表示部４に送信される。 In the processing calculation unit A of the controller 3, first, the posture of the imaging unit 11 is calculated by the camera posture calculation unit 30 based on the detection data of the imaging posture detection unit 13, while on the other hand, based on the detection data of the vehicle posture detection unit 20. The vehicle attitude calculation unit 32 calculates the attitude of the vehicle 2. Next, the rotation determination calculation unit 31 determines the rotation of the imaging unit 11 in response to the calculation results of the camera posture calculation unit 30 and the vehicle posture calculation unit 32. This rotation offsets the attitude of the vehicle 2 and represents a change in the attitude of the camera 10 with respect to the vehicle 2. Next, in response to the captured image input to the video acquisition unit 33 and the calculation result of the rotation determination calculation unit 31, when the rotation determination calculation unit 31 determines that the imaging unit 11 is in the rotation state, the video rotation processing unit 34. Then, based on the calculation result of the camera posture calculation unit 30, the video rotation processing of the captured image is performed. Thereafter, the captured image or the image after the video rotation process is transmitted from the transmission unit 39 to the display unit 4.
　こうして、撮像姿勢検出部１３及び車両姿勢検出部２０の検出データに基づいて撮影画像である実画像が処理演算部Ａによって回転補正される。よって、撮像部１１の傾きの検出精度が向上し、表示部４に表示される画像が水平な画像となる精度が向上する。 Thus, based on the detection data of the imaging posture detection unit 13 and the vehicle posture detection unit 20, a real image that is a captured image is rotationally corrected by the processing calculation unit A. Therefore, the detection accuracy of the inclination of the imaging unit 11 is improved, and the accuracy with which the image displayed on the display unit 4 becomes a horizontal image is improved.
[第４実施形態]
　本実施形態では、防犯カメラとして車室内のカメラ１０を使用する場合について説明する。車両２に搭載された各種センサと連携し、不審者の侵入を感知して、その時の映像をカメラ１０で記録する。カメラ１０の撮像姿勢検出部１３として用いられる加速度センサ等のセンサ情報を用いて、不法侵入を検知することも可能である、記録した映像は、無線でユーザの携帯端末等に通知してもよい。また、不法侵入時以外でも、ユーザは携帯端末等から必要に応じて車室内のカメラ１０の映像を確認可能に構成することもできる。 [Fourth embodiment]
This embodiment demonstrates the case where the camera 10 in a vehicle interior is used as a security camera. In cooperation with various sensors mounted on the vehicle 2, the intrusion of a suspicious person is detected, and the video at that time is recorded by the camera 10. It is also possible to detect illegal intrusion using sensor information such as an acceleration sensor used as the imaging posture detection unit 13 of the camera 10. The recorded video may be notified wirelessly to the user's portable terminal or the like. . In addition, the user can also be configured to be able to check the video of the camera 10 in the vehicle compartment as necessary from a portable terminal or the like even during illegal intrusion.
[第５実施形態]
　上記の実施形態では、撮像姿勢検出部１３により撮像部１１の姿勢変更が検出された場合に、コントローラ３の処理演算部Ａの演算が行われる。ただ、車両２が走行中には、道路事情等の影響を受けて車内のカメラ１０が振動し、この振動により撮像部１１の姿勢変更が検出する場合もある。しかしながら、カメラ１０の振動に対しては撮像部１１の回転補正が不要な場合が多い。そこで、撮像姿勢検出部１３においてカメラ１０の加速度変化からカメラ１０の動作が振動状態であるか否かを判定し、カメラ１０の動作が振動状態と判定された場合は処理演算部Ａの演算（回転補正）を行わないように構成してもよい。 [Fifth Embodiment]
In the above embodiment, when the posture change of the image pickup unit 11 is detected by the image pickup posture detection unit 13, the calculation of the processing calculation unit A of the controller 3 is performed. However, when the vehicle 2 is traveling, the camera 10 in the vehicle vibrates due to the influence of road conditions and the like, and the posture change of the imaging unit 11 may be detected by this vibration. However, in many cases, the rotation correction of the imaging unit 11 is not necessary for the vibration of the camera 10. Therefore, the imaging posture detection unit 13 determines whether or not the operation of the camera 10 is in a vibration state from the acceleration change of the camera 10, and if the operation of the camera 10 is determined to be in the vibration state, the calculation (A You may comprise so that rotation correction) may not be performed.
　カメラ１０の振動による加速度変化はカメラ１０の通常の姿勢変更操作時の加速度変化より格段に速い。このことから、例えば、カメラ１０の撮像姿勢検出部１３で検出される加速度変化と設定されるしきい値（例えば、カメラ１０を変更操作する際の最大の加速度変化）とを比較することで、カメラ１０の動作が振動状態であるか否かを判定することができる。こうして、カメラ１０の動作が振動状態と判定された場合に処理演算部Ａの演算（回転補正）を行わないことにより、コントローラ３における演算負荷を低減することができる。 Acceleration change due to vibration of camera 10 is much faster than acceleration change during normal posture change operation of camera 10. From this, for example, by comparing the acceleration change detected by the imaging posture detection unit 13 of the camera 10 with a set threshold value (for example, the maximum acceleration change when changing the camera 10), It can be determined whether or not the operation of the camera 10 is in a vibrating state. Thus, when the operation of the camera 10 is determined to be in the vibration state, the calculation load on the controller 3 can be reduced by not performing the calculation (rotation correction) of the processing calculation unit A.

(1) As shown in FIG. 5, the vehicle interior camera device may be configured such that the base end side 12 b of the flexible arm 12 is rotatable about the axis of the flexible arm 12 with respect to the vehicle attachment portion 15. If it carries out like this, the direction switching of the front-back and left-right in the vehicle 2 of the camera 10 will become easy.
（２）また、図６（ａ）に示すように、カメラ１０は、フレキシブルアーム１２の一部が収納自在に構成してもよい。カメラ１０を使用する際には、図６（ｂ）に示すように、フレキシブルアーム１２を引き伸ばして、カメラ１０の位置を移動させる。こうすることで、カメラ１０の不使用時に車室内カメラ装置全体をコンパクトにできる。 (2) Moreover, as shown to Fig.6 (a), the camera 10 may comprise a part of flexible arm 12 so that accommodation is possible. When the camera 10 is used, the position of the camera 10 is moved by extending the flexible arm 12 as shown in FIG. By doing so, the entire vehicle interior camera device can be made compact when the camera 10 is not used.
（３）上記の第５実施形態では、カメラ１０の動作が振動状態である場合には処理演算部Ａの演算（回転補正）を行われないように構成したが、これとは逆に、カメラ１０の姿勢の変更操作が検出された場合にのみ処理演算部Ａの演算（回転補正）を行うようしてもよい。例えば、カメラ１０の姿勢の変更操作によりフレキシブルアーム１２の基端側１２ｂも同時に動作するよう構成することで、基端側１２ｂの動作検出によってカメラ１０の姿勢変更操作を検出することができる。 (3) In the fifth embodiment, when the operation of the camera 10 is in a vibration state, it is configured so that the calculation (rotation correction) of the processing calculation unit A is not performed. The calculation (rotation correction) of the processing calculation unit A may be performed only when ten posture change operations are detected. For example, by configuring the base end side 12b of the flexible arm 12 to operate simultaneously by the operation of changing the posture of the camera 10, the posture change operation of the camera 10 can be detected by detecting the operation of the base end side 12b.
（４）上記の実施形態において、カメラ１０を支持するフレキシブルアーム１２は必ずしも全体がフレキシブルな構成である必要はなく、部分的にフレキシブルである構成であってもよい。 (4) In the above-described embodiment, the flexible arm 12 that supports the camera 10 does not necessarily have a flexible configuration as a whole, and may be configured to be partially flexible.
（５）上記の実施形態では、カメラ１０の設置位置として運転席２５側の中央ピラー２７を例に示したが、カメラ１０の設置位置は、車両２の天井、運転席２５側の前方ピラー、運転席２５のシート本体、助手席のシート本体、助手席側のピラーであってもよい。 (5) In the above embodiment, the central pillar 27 on the driver's seat 25 side is shown as an example of the installation position of the camera 10, but the installation position of the camera 10 is the ceiling of the vehicle 2, the front pillar on the driver's seat 25 side, The seat body of the driver seat 25, the seat body of the passenger seat, and the pillar on the passenger seat side may be used.
（６）カメラ１０は、必ずしもユーザが手動で移動させる必要はなく、遠隔操作により撮像部１１の向きを変更するようにしてもよい。 (6) The camera 10 is not necessarily moved manually by the user, and the orientation of the imaging unit 11 may be changed by remote operation.
　本発明は、各種車両の運転操作中や防犯上等における車室内の画像確認に広く利用することができる。 The present invention can be widely used for checking images in the vehicle interior during driving operations of various vehicles or for crime prevention.
