Description

この発明は、車載撮影手段による撮影を制御する撮影制御装置に関し、特に画像認識用に画質を向上した撮影制御装置に関する。   The present invention relates to a photographing control device that controls photographing by an in-vehicle photographing means, and particularly to a photographing control device that improves image quality for image recognition.

近年、自車両周辺を撮影し、画像認識によって歩行者などを検出する技術が考案されている。さらに、夜間において画像を得る手法として特許文献1〜3が開示するように赤外線画像を利用することが行なわれてきた。   2. Description of the Related Art In recent years, a technique has been devised for photographing a periphery of a host vehicle and detecting a pedestrian or the like by image recognition. Furthermore, as disclosed in Patent Documents 1 to 3, techniques for obtaining images at night have been made using infrared images.

特開2005−159392号公報JP 2005-159392 A 特開2005−159710号公報JP 2005-159710 A 特開2005−167556号公報JP 2005-167556 A

自車両周辺を撮影する場合、カメラは車室内から外に向けて周辺を撮影するように構成する。通常、カメラは可視光領域や近赤外領域の波長の光を外から受け、この領域にかかる映像を撮影することができる。   When photographing the periphery of the host vehicle, the camera is configured to photograph the periphery from the passenger compartment to the outside. Usually, a camera receives light having a wavelength in the visible light region or near-infrared region from the outside, and can take an image of this region.

ここで、昼は自然光が強いため、可視光領域のパワーは強く、近赤外光領域は比較的弱い。一方、夜は自然光が弱いため、可視光領域および近赤外領域ともにパワーが弱い。但し、夜間であっても近赤外光を照射すればその反射光によって近赤外領域が強くなる。また、近赤外光には周辺の人物(歩行者や他車両の乗員など)に眩惑を生ずることなく十分な光量を照射することができるという利点がある。   Here, since natural light is strong at daytime, the power in the visible light region is strong and the near-infrared light region is relatively weak. On the other hand, since natural light is weak at night, the power is weak in both the visible light region and the near infrared region. However, even at night, if near infrared light is irradiated, the near infrared region is strengthened by the reflected light. In addition, near infrared light has an advantage that a sufficient amount of light can be emitted without causing dazzling to surrounding persons (such as pedestrians and occupants of other vehicles).

従来、夜間に近赤外光を照射して撮影を行なう場合には、カメラは可視光領域と近赤外領域の両方の領域の光を周辺から受けることになる。しかしながら、近赤外領域と可視光領域とを同時に撮影すると、画像の色がぼやけたり現状にない点が写ってしまうことがあり、画質が低下するという問題点があった。   Conventionally, when photographing is performed by irradiating near infrared light at night, the camera receives light from both the visible light region and the near infrared region from the periphery. However, if the near-infrared region and the visible light region are photographed at the same time, the color of the image may be blurred or a point that is not present may appear, resulting in a problem that the image quality deteriorates.

制御部11による制御とフィルタリングの具体例を図2に示す。パターン1の動作では、日中には近赤外光を照射せず、赤外領域カットフィルタ(IRフィルタ)をかけて撮影し、夜は近赤外光を照射してフィルタをかけずに撮影する。また、パターン2の動作では、日中には近赤外光を照射せずIRフィルタをかけて撮影し、夜間は近赤外光を照射して可視光領域側(短波長側)をカットする、すなわち赤外側(長波長側)を通過させるハイパスフィルタをかけて撮影する。パターン3の動作では、日中には近赤外光を照射せずIRフィルタをかけて撮影し、夜間は近赤外光を照射して近赤外領域を選択的に通過させるバンドパスフィルタをかけて撮影する。   A specific example of control and filtering by the control unit 11 is shown in FIG. In the pattern 1 operation, the near-infrared light is not irradiated during the day, but the infrared region cut filter (IR filter) is used for the image, and the near-infrared light is applied at night without the filter. To do. In the pattern 2 operation, the IR filter is not applied during the day without irradiating near infrared light, and the infrared light is irradiated at night to cut the visible light region side (short wavelength side). That is, the image is taken with a high-pass filter that passes the infrared side (long wavelength side). In the operation of Pattern 3, a band-pass filter that irradiates the IR filter without irradiating near infrared light during the day and selectively passes through the near infrared region by irradiating the near infrared light at night. Take a picture.

さらに、パターン4の動作では、日中には近赤外光を照射せず、フィルタをかけずに撮影し、夜間は近赤外光を照射し、赤外側を通過させるハイパスフィルタをかけて撮影する。パターン5の動作では、日中には近赤外光を照射せず、フィルタをかけずに撮影し、夜間は近赤外光を照射し、近赤外領域を選択的に通過させるバンドパスフィルタをかけて撮影する。   Furthermore, in the operation of pattern 4, the image is taken without applying near-infrared light during the day and without applying a filter, and at night, the image is taken with a high-pass filter that applies near-infrared light and passes through the infrared side. To do. In the operation of pattern 5, a band-pass filter that does not irradiate near-infrared light during the day and shoots without filtering, irradiates near-infrared light at night, and selectively passes through the near-infrared region. To shoot.

パターン1〜5のいずれの動作を採用する場合であっても、日中など周囲が明るい状況と、夜間など周囲が暗い状況とで近赤外照射装置27の消灯/点灯を切り換えると共に撮像素子14に入射する光の波長を変更し、画像のにじみなどを防止して画質を向上することができる。   Even when any of the operations of patterns 1 to 5 is adopted, the near-infrared irradiation device 27 is turned off / on and the imaging element 14 is switched between a bright environment such as daytime and a dark environment such as nighttime. By changing the wavelength of light incident on the image, it is possible to improve image quality by preventing bleeding of the image.

さらに言えば、パターン1〜3では、周囲が明るい状況下での画質を向上し、パターン2〜5では周囲が暗い状況下での画質を向上することができる。また、パターン1,4,5では、使用するフィルタが一つであるために製造コストを削減することが可能である。   Furthermore, the patterns 1 to 3 can improve the image quality under a bright environment, and the patterns 2 to 5 can improve the image quality under a dark environment. Further, in the patterns 1, 4 and 5, since only one filter is used, it is possible to reduce the manufacturing cost.

つぎに、アクチュエータ12によるフィルタ13の駆動例について説明する。図3は、フィルタをスライドさせることで切り替える構成例である。フィルタ13aは、日中用のフィルタと夜間用のフィルタとを一体に構成しており、単一のスライド動作で切替が可能である。また、フィルタ13b,13cはそれぞれ単独のフィルタであり、個別制御が可能となっている。   Next, an example of driving the filter 13 by the actuator 12 will be described. FIG. 3 is a configuration example in which switching is performed by sliding a filter. The filter 13a is configured integrally with a daytime filter and a nighttime filter, and can be switched by a single slide operation. The filters 13b and 13c are independent filters, and can be individually controlled.

他の構成として、フィルタを円形板に設けて回動(もしくは回転)させて切り替えることもできる。図4は、回動によってフィルタを切り替える場合の構成例である。フィルタ13dはフィルタもしくは開口部(フィルタ無し)から2通りを選択可能とする円形板であり、フィルタ13eはフィルタもしくは開口部(フィルタ無し)から3通りを選択可能とする円形板である。   As another configuration, the filter can be provided on a circular plate and rotated (or rotated) for switching. FIG. 4 is a configuration example when the filter is switched by turning. The filter 13d is a circular plate that can select two types from a filter or an opening (no filter), and the filter 13e is a circular plate that can select three types from a filter or an opening (no filter).

なお、撮像素子14がレンズを介して集光した光を撮影する場合、レンズとフィルタの位置関係は、図5に示すようにレンズ15をフィルタ13の前段に置く構成としても良いし、レンズ15をフィルタ13の後段におく構成としても良い。   In the case where the image sensor 14 captures light collected through the lens, the positional relationship between the lens and the filter may be such that the lens 15 is placed in front of the filter 13 as shown in FIG. May be placed after the filter 13.

つづいて、制御部11による切替の判断について説明する。制御部11は、図1に示したようにヘッドライト(前照灯)25の動作状態を取得している。そこでヘッドライト25に連動させてヘッドライト25の点灯時には周囲が暗い状況であると判断し、ヘッドライト25の消灯時には周囲が明るい状況であると判断することができる。なお、ここではヘッドライト25を例に説明を行なったが、スモールランプ(車幅灯)など任意の車載灯具に連動させることができる。   Next, switching determination by the control unit 11 will be described. The control unit 11 acquires the operating state of the headlight (headlight) 25 as shown in FIG. Therefore, in conjunction with the headlight 25, it can be determined that the surroundings are dark when the headlights 25 are turned on, and the surroundings are bright when the headlights 25 are turned off. Although the headlight 25 has been described as an example here, the headlight 25 can be interlocked with any on-vehicle lamp such as a small lamp (vehicle width lamp).

また、照度センサ26が測定した自車両周辺の明るさ(照度値)を取得し、たとえば所定の閾値と比較することで、周囲が明るい状況であるか暗い状況であるかを判断するよう構成してもよい。   Further, the brightness (illuminance value) around the own vehicle measured by the illuminance sensor 26 is acquired and compared with a predetermined threshold, for example, to determine whether the surroundings are bright or dark. May be.

さらに、日中であるか夜間であるかは、時間情報によっても判断することができる。時間情報による判断処理について、図6のフローチャートを参照して説明する。同図に示す処理では、制御部11は、まずナビゲーション装置22などから日付情報および時刻情報を取得する(ステップS101)。   Furthermore, whether it is daytime or nighttime can also be determined from time information. The determination process based on time information will be described with reference to the flowchart of FIG. In the process shown in the figure, the control unit 11 first acquires date information and time information from the navigation device 22 or the like (step S101).

つぎに、現在の日付に対応する日出・日没時刻を取得し(ステップS102)、現在時刻が日出時刻以降かつ日没時刻以前であるならば(ステップS103,Yes)、日中であると判断して近赤外照射装置27を消灯状態とする(ステップS104)とともに昼用のフィルタ制御を行ない(ステップS105)、日出前もしくは日没後である場合には(ステップS103,No)、夜間であると判断して近赤外照射装置27を点灯状態とする(ステップS106)とともに夜用のフィルタ制御を行なう(ステップS107)。   Next, a sunrise / sunset time corresponding to the current date is acquired (step S102), and if the current time is after the sunrise time and before the sunset time (step S103, Yes), it is daytime. And the near-infrared irradiation device 27 is turned off (step S104) and the daytime filter control is performed (step S105). If it is before sunrise or after sunset (No at step S103), It is determined that it is nighttime, the near infrared irradiation device 27 is turned on (step S106), and nighttime filter control is performed (step S107).

なお、日付情報や時刻情報は、撮像装置1自身にタイマーを持たせても良いし、ナビゲーション装置21以外の装置から取得しても良い。また、日付に対応する日出・日没時刻は、例えばHDDなどにデータベースとして持たせておくことが好適である。   Note that the date information and time information may be provided with a timer in the imaging device 1 itself, or may be obtained from a device other than the navigation device 21. Further, the sunrise / sunset time corresponding to the date is preferably stored as a database in an HDD, for example.

ところで、トンネル内や高架下などでは時刻が日中であっても周囲が暗く、赤外光の照射制御と夜用のフィルタ制御を行なうことが望ましい。そこで、制御部11は、図7に示すように、ナビゲーション装置21から現在の位置情報を取得し(ステップS201)、位置情報と制御との対応表を参照する(ステップS202)。   By the way, in a tunnel or under an elevated route, the surroundings are dark even during the daytime, and it is desirable to perform infrared light irradiation control and night filter control. Therefore, as shown in FIG. 7, the control unit 11 acquires the current position information from the navigation device 21 (step S201), and refers to the correspondence table between the position information and the control (step S202).

そして、現在位置が対応表に存在する、すなわち現在位置に対して特定の制御が指定されている場合(ステップS203,Yes)には、対応表に指定された制御を実行する(ステップS204)。   When the current position exists in the correspondence table, that is, when specific control is designated for the current position (Yes in step S203), the control designated in the correspondence table is executed (step S204).

なお、位置情報と制御との対応表は、例えばHDDなどにデータベースとして持たせておく。また、この対応表には既に述べたように日中であっても近赤外光の照射と夜用のフィルタ制御を行なう場所に限らず、十分な照明が行なわれている場所など夜間であっても近赤外光の照射停止と昼用のフィルタ制御を行なう場所についても記載しておくことが望ましい。   The correspondence table between the position information and the control is provided as a database in, for example, an HDD. In addition, as described above, this correspondence table is not limited to places where near-infrared light irradiation and nighttime filter control are performed even during the daytime. However, it is desirable to describe the place where the irradiation of near infrared light is stopped and the daytime filter control is performed.

なお、近赤外照射装置27は、図8に示すようにハロゲンランプにハイパスフィルタをかけて可視光領域をカットすることで実現しても良いし、図9に示すように近赤外領域にピークを有するLEDを使用してもよい。なお、LEDによって近赤外照明を行い、撮像素子14にバンドパスフィルタ(BPF)をかけて撮影する場合には、LEDのピークスペクトルがバンドパスフィルタの通過帯域に入るようにする。   The near-infrared irradiation device 27 may be realized by cutting a visible light region by applying a high-pass filter to a halogen lamp as shown in FIG. 8, or in the near-infrared region as shown in FIG. An LED having a peak may be used. In addition, when performing near-infrared illumination with LED and image | photographing by applying the band pass filter (BPF) to the image pick-up element 14, it is made for the peak spectrum of LED to enter into the pass band of a band pass filter.

また、近赤外照射装置27は、撮像装置からの制御に限らず、ユーザ(車両乗員、特に運転者)からの操作によって点灯/消灯を切り替えることとしても良い。この場合、撮像装置は近赤外照射装置27の点灯状態に連動してフィルタ制御を行なうこともできる。図10は、近赤外光の照明装置である近赤外照射装置27に連動する撮像装置2の概要構成図である。   The near-infrared irradiation device 27 is not limited to control from the imaging device, and may be switched on / off by an operation from a user (vehicle occupant, particularly a driver). In this case, the imaging apparatus can also perform filter control in conjunction with the lighting state of the near infrared irradiation device 27. FIG. 10 is a schematic configuration diagram of the imaging device 2 that is linked to the near infrared irradiation device 27 that is a near infrared light illumination device.

同図では、近赤外照射装置27は、ユーザによるスイッチ28の操作に従って点灯状態と消灯状態とを切り換える。そして、撮像装置2内部の制御部11aは、近赤外照射装置27が消灯状態である場合に昼用のフィルタ制御を実行し、近赤外照射装置27が点灯状態である場合に夜用のフィルタ制御を実行する。尚、近赤外照射装置27の点灯・消灯状態を判断するには、前述したスイッチ28のオン・オフ状態に基づくようにしても良い。   In the figure, the near-infrared irradiation device 27 switches between a lighting state and a light-off state according to the operation of the switch 28 by the user. And the control part 11a inside the imaging device 2 performs daytime filter control when the near-infrared irradiation device 27 is in the off state, and when the near-infrared irradiation device 27 is in the lighting state, it is for night use. Perform filter control. In order to determine the on / off state of the near-infrared irradiation device 27, it may be based on the on / off state of the switch 28 described above.

その他の構成および動作は、図1に示した撮像装置1と同様であるので、同一の構成要素には同一の符号を付して説明を省略する。   Since other configurations and operations are the same as those of the imaging apparatus 1 shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted.

これまでの説明では、アクチュエータ12の動作によってフィルタ13を駆動することで可視光の撮影と近赤外の撮影とを切り替える場合について説明をおこなったが、本発明の他の構成として、例えば、可視光撮影用の撮影手段と近赤外撮影用の撮影手段とを個別に設け撮影手段の選択によって撮影状態を切り替えるように構成してもよい。   In the above description, the case where the visible light imaging and the near infrared imaging are switched by driving the filter 13 by the operation of the actuator 12 has been described. However, as another configuration of the present invention, for example, visible An imaging unit for optical imaging and an imaging unit for near-infrared imaging may be provided separately, and the imaging state may be switched by selecting the imaging unit.

撮影素子の選択によって撮影状態を切り替える場合の構成例を図11に示す。同図に示すように、撮像装置3は、その内部に撮像素子14aおよび撮像素子14bを備えている。そして、撮像素子14aにはフィルタ13fを、撮像素子14bにはフィルタ13gをかけ、制御部11cがスイッチ16を切り替えることで、撮像素子14aの撮影結果と撮像素子14bの撮影結果のいずれを画像処理装置21に出力するかを制御している。   FIG. 11 shows a configuration example when the shooting state is switched by selecting the shooting element. As shown in the figure, the imaging device 3 includes an imaging element 14a and an imaging element 14b. Then, the filter 13f is applied to the image pickup device 14a, the filter 13g is applied to the image pickup device 14b, and the control unit 11c switches the switch 16. Thus, either the image pickup result of the image pickup device 14a or the image pickup result of the image pickup device 14b is subjected to image processing. It controls whether to output to the device 21.

このように、電気的スイッチによって切替を行なうことで、アクチュエータで機構的に切替を行なう場合に比して切替制御の高速化と駆動電力の低減を実現することができる。又は、電子制御によって、波長の通過領域を変更できるフィルタを設けるようにしても良い。   As described above, by performing the switching by the electric switch, it is possible to realize the speeding up of the switching control and the reduction of the driving power as compared with the case where the switching is mechanically performed by the actuator. Or you may make it provide the filter which can change the passage region of a wavelength by electronic control.

その他の構成および動作は、図1に示した撮像装置1と同様であるので、同一の構成要素には同一の符号を付して説明を省略する。   Since other configurations and operations are the same as those of the imaging apparatus 1 shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted.

また、他の構成例として、フィルタとその制御を撮像装置から独立させても良い。図12に示した構成では、撮像装置4の外部に撮影制御装置5を独立に設け、撮影制御装置5の内部に制御部11、アクチュエータ12およびフィルタ13を持たせている。その他の構成および動作は、図1に示した撮像装置1と同様であるので、同一の構成要素には同一の符号を付して説明を省略する。また今まで説明した制御部は、撮像装置内に設けているが、この他、画像処理装置に設けたり、あるいはこれらから独立した制御部として設けるようにしても良い。   As another configuration example, the filter and its control may be made independent of the imaging device. In the configuration illustrated in FIG. 12, the imaging control device 5 is provided independently outside the imaging device 4, and the control unit 11, the actuator 12, and the filter 13 are provided inside the imaging control device 5. Since other configurations and operations are the same as those of the imaging apparatus 1 shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted. Moreover, although the control part demonstrated so far is provided in the imaging device, you may make it provide in an image processing apparatus, or as a control part independent from these in addition to this.

上述してきたように、本実施例にかかる撮影制御装置は、フィルタの選択や撮像素子の選択によって日中など周囲が明るい状況では可視光を選択的に撮影し、夜間など周囲が暗い状況では近赤外光を選択的に撮影するので、画像の色がぼやけたり現状にない点が写ってしまうなどの画質が低下を防止することができる。   As described above, the imaging control apparatus according to the present embodiment selectively captures visible light in a bright environment such as daytime by selecting a filter or an image sensor and closes in a dark environment such as nighttime. Since infrared light is selectively photographed, it is possible to prevent the image quality from being deteriorated, such as blurring of the image color or a point that is not present.

以上のように、本発明にかかる撮影制御装置は、車両からの撮影の制御に有用であり、特に周囲の明るさに合わせた画質向上に適している。   As described above, the imaging control device according to the present invention is useful for controlling imaging from a vehicle, and is particularly suitable for improving image quality in accordance with ambient brightness.
