　この発明は、運転者の前方視界に表示情報を重ねて表示するヘッドアップディスプレイ（以下、ＨＵＤと記載する）の表示制御装置およびこれを備えたナビゲーション装置に関する。 The present invention relates to a display control device for a head-up display (hereinafter referred to as HUD) that displays display information superimposed on a driver's forward view, and a navigation device equipped with the display control device.
　特許文献１には、情報の重要度に応じてＨＵＤによる情報の表示位置を変更する表示システムが記載されている。この表示システムでは、重要度が高い情報を、ＨＵＤにおける表示領域のうち、運転者が前方の走行路から視線を逸らすことなく情報を読み取り可能な中央表示領域に表示し、重要度が低い情報をＨＵＤの周辺表示領域に表示している。これにより、中央表示領域に表示された重要度が高い情報は、運転者が視線を移動させることなく視認できる。 Patent Document 1 describes a display system that changes the display position of information by HUD according to the importance of information. In this display system, information with high importance is displayed in a central display area where the driver can read information without diverting his gaze from the driving road ahead of the display area in the HUD, and information with low importance is displayed. It is displayed in the peripheral display area of the HUD. Thereby, the information with high importance displayed in the central display area can be visually recognized without the driver moving his / her line of sight.
　また、特許文献２には、運転者の左目と右目に視差を与えて情報を３次元表示するＨＵＤ装置が記載されている。このＨＵＤ装置では、道路、交差点または道路沿いの建物などの地図情報を運転者の前方視界の焦点位置に重ねて３次元表示することができる。これにより、運転者が視線または目の焦点をずらすことなく情報を視認できる。 Further, Patent Document 2 describes a HUD device that displays parallax to the left and right eyes of a driver to display information three-dimensionally. In this HUD device, map information such as roads, intersections or buildings along the roads can be displayed in a three-dimensional manner by superimposing them on the focal position of the driver's front view. Thereby, the driver can visually recognize the information without shifting the line of sight or the focus of the eyes.
　特許文献３には、運転者の注視している物体を検出してその物体上に重なって結像するように情報を表示するＨＵＤ装置が記載されている。このＨＵＤ装置では、時々刻々と変わり得る運転者の注視物体に動的に情報が重ねて表示されるので、運転者は、視線を移動させず、かつ目の焦点距離を合わせ直すことなく、情報を視認できる。 Patent Document 3 describes a HUD device that detects an object that is being watched by a driver and displays information so as to form an image overlapping the object. In this HUD device, information is dynamically superimposed and displayed on the driver's gaze object, which can change from moment to moment, so that the driver does not move the line of sight and adjusts the focal length of the eyes. Can be visually recognized.

　ＨＵＤでは、車両情報、経路案内などの情報を、運転者の前方視界の焦点位置に重ねて表示することで、運転者は、少ない視線移動で素早く情報を視認することができる。
　しかしながら、特許文献１から特許文献３までに記載されるいずれの発明においても、前方視界で運転者が注目したい対象物と、この対象物とは無関係の表示情報とが重なって表示された場合、対象物と情報の両方が見難くなるという課題があった。 In HUD, information such as vehicle information and route guidance is displayed superimposed on the focal position of the driver's forward field of view, so that the driver can quickly view the information with a small amount of line-of-sight movement.
However, in any of the inventions described in Patent Literature 1 to Patent Literature 3, when an object that the driver wants to pay attention to in front view and display information that is irrelevant to the object are displayed in an overlapping manner, There was a problem that it was difficult to see both the object and the information.
　この発明は、上記課題を解決するもので、経路案内に関係する道路標示情報を見やすく表示できる表示制御装置およびナビゲーション装置を得ることを目的とする。 This invention solves the said subject, and it aims at obtaining the display control apparatus and navigation apparatus which can display the road marking information relevant to route guidance easily.
　この発明に係る表示制御装置は、標示情報取得部、表示情報生成部および出力制御部を備える。標示情報取得部は、車両前方で検出された道路標示情報から、経路案内に関係する道路標示情報を取得する。表示情報生成部は、標示情報取得部により取得された道路標示情報を、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示させるための表示情報を生成する。出力制御部は、表示装置に対して表示情報を出力する。 The display control device according to the present invention includes a sign information acquisition unit, a display information generation unit, and an output control unit. The sign information acquisition unit acquires road sign information related to route guidance from road sign information detected in front of the vehicle. The display information generation unit generates display information for highlighting the road marking information acquired by the marking information acquisition unit so that the road marking information overlaps with the corresponding real road marking information in the forward field of view. The output control unit outputs display information to the display device.
　この発明によれば、経路案内に関係する道路標示情報の表示情報が前方視界の対応する道路標示情報に重ねて強調表示されるので、経路案内に関係する道路標示情報を見やすく表示できるという効果がある。 According to the present invention, since the display information of the road marking information related to the route guidance is highlighted and superimposed on the corresponding road marking information in the forward field of view, there is an effect that the road marking information related to the route guidance can be easily displayed. is there.

　以下、この発明をより詳細に説明するため、この発明を実施するための形態について、添付の図面に従って説明する。
実施の形態１．
　図１は、この発明の実施の形態１に係るナビゲーション装置１の機能構成を示すブロック図である。ナビゲーション装置１は、車両に搭載されて、目的地までの経路案内を実行する装置であり、位置測定部２、地図データ格納部３、操作部４、制御部５、表示部６を備え、ＨＵＤ７、距離測定部８および撮像部９に接続されている。ナビゲーション装置１の各部の動作は、制御部５によって統括的に制御される。 Hereinafter, in order to describe the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
1 is a block diagram showing a functional configuration of a navigation device 1 according to Embodiment 1 of the present invention. The navigation device 1 is a device that is mounted on a vehicle and performs route guidance to a destination. The navigation device 1 includes a position measurement unit 2, a map data storage unit 3, an operation unit 4, a control unit 5, and a display unit 6, and includes a HUD 7 The distance measuring unit 8 and the imaging unit 9 are connected. The operation of each part of the navigation device 1 is comprehensively controlled by the control part 5.
　位置測定部２は、自車の現在位置を測定する構成要素であり、例えば、ＧＰＳ（Ｇｌｏｂａｌ　Ｐｏｓｉｔｉｏｎｉｎｇ　Ｓｙｓｔｅｍ）受信機、方位センサおよび自車の車両制御装置に接続されている。ＧＰＳ受信機は、ＧＰＳ衛星からのＧＰＳ信号を受信して、このＧＰＳ信号に基づいて自車の現在位置（例えば、緯度経度）を検出する。方位センサは、自車の走行方向（例えば、方位）を検出するセンサであり、例えば、ジャイロセンサおよび方位センサから構成される。車両制御装置は、自車の車軸の単位時間当たりの回転数に応じたパルス信号を検出し、このパルス信号に基づいて自車の走行速度と走行距離を検出する。位置測定部２は、ＧＰＳ受信機によって検出された現在位置を、方位センサと車両制御装置によって検出された自車の走行方向、走行速度および走行距離に基づいて補正する。これにより、自車の正確な現在位置を検出することが可能となる。 The position measuring unit 2 is a component that measures the current position of the host vehicle, and is connected to, for example, a GPS (Global Positioning System) receiver, an orientation sensor, and a vehicle control device of the host vehicle. The GPS receiver receives GPS signals from GPS satellites and detects the current position (for example, latitude and longitude) of the vehicle based on the GPS signals. The direction sensor is a sensor that detects the traveling direction (for example, direction) of the host vehicle, and includes, for example, a gyro sensor and an direction sensor. The vehicle control device detects a pulse signal corresponding to the number of revolutions per unit time of the axle of the own vehicle, and detects the traveling speed and the traveling distance of the own vehicle based on the pulse signal. The position measuring unit 2 corrects the current position detected by the GPS receiver based on the traveling direction, traveling speed, and traveling distance of the host vehicle detected by the direction sensor and the vehicle control device. Thereby, it becomes possible to detect the exact current position of the own vehicle.
　地図データ格納部３は、地図データを記憶する記憶部であり、例えば、ＨＤＤ（Ｈａｒｄ　Ｄｉｓｋ　Ｄｒｉｖｅ）、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）などの記憶装置として実現される。なお、地図データ格納部３は、ナビゲーション装置１の外部から取得した地図データを記憶するものであってもよい。
　例えば、地図データ格納部３は、ネットワークを介して外部装置からダウンロードした地図データを記憶する。また、地図データ格納部３が、ＤＶＤ－ＲＯＭ（Ｄｉｇｉｔａｌ　Ｖｅｒｓａｔｉｌｅ　Ｄｉｓｋ－Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）、Ｂｌｕ－Ｒａｙ（登録商標）　Ｄｉｓｃ－ＲＯＭなどの記録媒体から読み出した地図データを記憶してもよい。 The map data storage unit 3 is a storage unit that stores map data, and is realized as a storage device such as an HDD (Hard Disk Drive) and a RAM (Random Access Memory). The map data storage unit 3 may store map data acquired from the outside of the navigation device 1.
For example, the map data storage unit 3 stores map data downloaded from an external device via a network. Further, the map data storage unit 3 may store map data read from a recording medium such as a DVD-ROM (Digital Versatile Disk-Read Only Memory) or Blu-Ray (registered trademark) Disc-ROM.
　操作部４は、ユーザからの情報入力を受け付ける構成要素であり、例えば、押しボタン装置、タッチパネルなどによって実現される。なお、タッチパネルは、表示部６と一体に構成されてもよい。操作部４を用いて現在位置から経路案内すべき目的地などが入力される。例えば、操作部４は、ユーザによって表示部６に表示された地図上の地点が指定された場合、この地点を目的地として受け付け、住所または電話番号が入力された場合、この住所または電話番号を、目的地を特定する目的地情報として受け付ける。 The operation unit 4 is a component that receives information input from the user, and is realized by, for example, a push button device, a touch panel, or the like. The touch panel may be configured integrally with the display unit 6. A destination to be route-guided from the current position is input using the operation unit 4. For example, when a point on the map displayed on the display unit 6 is designated by the user, the operation unit 4 accepts this point as a destination, and when an address or a telephone number is input, This is accepted as destination information for specifying a destination.
　表示部６は、地図表示と経路案内表示が行われるナビゲーション処理用のディスプレイであり、例えば、車室内の前方中央部に配置される。
　ＨＵＤ７は、表示情報をフロントウィンドウまたはコンバイナに投影表示するディスプレイである。また、ステレオ視差により表示情報を３次元表示する表示方式であってもよい。すなわち、ＨＵＤ７は、運転者の前方視界に重ねて情報を３次元表示でき、かつ、運転者から見た距離と奥行きが可変であればよい。
　ただし、この発明は、情報が、運転者の前方視界の対応する実在の道路標示情報に重なって見えるように表示されるので、投影表示する対象としては、フロントウィンドウが望ましい。 The display unit 6 is a display for navigation processing in which map display and route guidance display are performed, and is arranged, for example, in the front center portion of the passenger compartment.
The HUD 7 is a display that projects and displays display information on a front window or a combiner. Further, a display method in which display information is three-dimensionally displayed by stereo parallax may be used. In other words, the HUD 7 only needs to be able to display information three-dimensionally in a superimposed manner on the driver's forward field of view, and the distance and depth viewed from the driver are variable.
However, in the present invention, since the information is displayed so as to be superimposed on the corresponding actual road marking information in the driver's forward field of view, the front window is desirable as an object to be projected and displayed.
　距離測定部８は、レーザ光あるいはミリ波をプローブとして自車前方にある検出対象物と自車との距離を測定する測定部であり、自車の車体におけるノーズ部分または車室内側のフロントウィンドウの近傍などに配置される。
　検出対象物は、例えば、自車前方にある案内標識、路面標示、情報板などである。 The distance measuring unit 8 is a measuring unit that measures a distance between a detection object in front of the host vehicle and the host vehicle using a laser beam or a millimeter wave as a probe, and a nose portion in the body of the host vehicle or a front window on the vehicle interior It is arranged in the vicinity of.
The detection target object is, for example, a guide sign, a road marking, an information board, etc. in front of the host vehicle.
　撮像部９は、可視光領域あるいは赤外光領域での撮影が可能なカメラである。例えば、撮像部９は、自車のフロントウィンドウの車室内側でルームミラーの近傍に配置されて、フロントウィンドウ越しに自車の走行方向前方の予め定められた範囲の外界を撮影する。
　なお、カメラとしては、例えば、ＣＣＤ（Ｃｈａｒｇｅ　Ｃｏｕｐｌｅｄ　Ｄｅｖｉｃｅ）カメラ、あるいは、ＣＭＯＳ（Ｃｏｍｐｌｅｍｅｎｔａｒｙ　Ｍｅｔａｌ　Ｏｘｉｄｅ　Ｓｅｍｉｃｏｎｄｕｃｔｏｒ）カメラ、ステレオカメラなどを使用する。
　また、撮像部９は、撮像画像を、標示情報取得部５１において処理可能な画像データに画像処理する。例えば、フィルタリング、二値化処理などの画像処理を施して２次元配列の画素からなる画像データを生成する。 The imaging unit 9 is a camera capable of shooting in the visible light region or the infrared light region. For example, the imaging unit 9 is arranged in the vicinity of a room mirror on the vehicle interior side of the front window of the own vehicle, and images the outside of a predetermined range ahead of the traveling direction of the own vehicle through the front window.
As the camera, for example, a CCD (Charge Coupled Device) camera, a CMOS (Complementary Metal Oxide Semiconductor) camera, a stereo camera, or the like is used.
Further, the imaging unit 9 performs image processing on the captured image into image data that can be processed by the sign information acquisition unit 51. For example, image data including two-dimensional array pixels is generated by performing image processing such as filtering and binarization processing.
　また、実施の形態１に係る表示制御装置の機能は、制御部５が備えるＨＵＤ７の表示を制御する各機能により実現される。
　図２は、実施の形態１に係る表示制御装置の機能構成を示すブロック図であり、実施の形態１に係る表示制御装置の機能となる制御部５の機能を示している。
　図２に示すように、制御部５は、ナビゲーション処理を行う機能としてナビゲーション処理部５０を備え、ＨＵＤ７の表示を制御する機能として標示情報取得部５１、表示情報生成部５２、出力制御部５３を備える。 Moreover, the function of the display control apparatus according to the first embodiment is realized by each function for controlling the display of the HUD 7 included in the control unit 5.
FIG. 2 is a block diagram illustrating a functional configuration of the display control apparatus according to the first embodiment, and illustrates functions of the control unit 5 serving as functions of the display control apparatus according to the first embodiment.
As shown in FIG. 2, the control unit 5 includes a navigation processing unit 50 as a function for performing navigation processing, and includes a labeling information acquisition unit 51, a display information generation unit 52, and an output control unit 53 as functions for controlling display of the HUD 7. Prepare.
　ナビゲーション処理部５０は、地図表示、経路探索、経路案内といったナビゲーション処理を行う。例えば、ナビゲーション処理部５０は、出発地、目的地および地図データに基づいて、出発地から目的地までの経路を探索する。例えば、位置測定部２によって測定された自車の現在位置を出発地とする。目的地は、操作部４を用いてユーザから受け付けた地点でもよいが、目的地候補として予め登録された地点であってもよい。
　また、ナビゲーション処理部５０は、探索結果の経路候補のうち、ユーザに選択された経路を経路案内する。 The navigation processing unit 50 performs navigation processing such as map display, route search, and route guidance. For example, the navigation processing unit 50 searches for a route from the departure place to the destination based on the departure place, the destination, and the map data. For example, the current position of the vehicle measured by the position measurement unit 2 is set as the departure place. The destination may be a point received from the user using the operation unit 4 or may be a point registered in advance as a destination candidate.
Further, the navigation processing unit 50 provides route guidance for the route selected by the user among the route candidates of the search result.
　標示情報取得部５１は、自車前方で検出された道路標示情報から、経路案内に関係する道路標示情報を取得する。ここで、道路標示情報とは、道路の交通案内に関する標示情報であり、例えば、案内標識、路面標示、情報板、これらの内容およびこれらと自車との距離が挙げられる。案内標識については、案内標識の位置と案内標識の内容が道路標示情報となる。案内標識の内容には、方面を示す地名とその方向を示す矢印標示などがある。
　路面標示については、路面標示の位置とその内容が道路標示情報となる。路面標示の内容には、車線の直進、右左折などの進行方向別の通行区分を示す矢印標示などがある。
　情報板については、情報板の位置に加え、情報板が表示している「大阪まで３０ｋｍ、渋滞あり、所要時間４０分」といった交通情報の内容も道路標示情報となる。 The sign information acquisition unit 51 acquires road sign information related to route guidance from road sign information detected in front of the host vehicle. Here, the road marking information is marking information related to road traffic guidance, and includes, for example, guidance signs, road markings, information boards, their contents, and the distance between them and the vehicle. As for the guide sign, the position of the guide sign and the content of the guide sign become road marking information. The contents of the guide sign include a place name indicating the direction and an arrow sign indicating the direction.
As for the road marking, the position and the content of the road marking become road marking information. The contents of the road marking include an arrow marking indicating a traffic division according to the traveling direction, such as a straight lane or a left / right turn.
Regarding the information board, in addition to the position of the information board, the contents of the traffic information such as “30 km to Osaka, traffic jam, required time 40 minutes” displayed on the information board is also the road marking information.
　標示情報取得部５１は、例えば、撮像部９によって自車の前方で検出された道路標示情報を、ナビゲーション処理部５０における経路案内に関係する道路標示情報と経路案内に関係しない道路標示情報とに分類し、経路案内に関係する道路標示情報を取得する。
　分類の方法としては、例えば、道路標示情報における、案内標識、路面標示、情報板とこれらの内容と走行予定経路の経路案内情報とを比較して経路案内に関係する情報を特定する方法が採用される。 For example, the sign information acquisition unit 51 converts road sign information detected in front of the host vehicle by the imaging unit 9 into road sign information related to route guidance in the navigation processing unit 50 and road sign information not related to route guidance. Classify and obtain road marking information related to route guidance.
As a classification method, for example, a method of identifying information related to route guidance by comparing the guidance signs, road markings, information boards and their contents with the route guidance information of the planned travel route in the road marking information is adopted. Is done.
　さらに、標示情報取得部５１は、撮像部９の画像処理で得られた画像データを画像解析して道路標示情報の内容を特定する。例えば、道路標示情報が案内標識である場合、案内標識の地名、矢印標示などの標示内容と、この標示内容が記載された案内標識中の位置が特定される。 Further, the sign information acquisition unit 51 performs image analysis on the image data obtained by the image processing of the image pickup unit 9 to identify the content of the road sign information. For example, when the road sign information is a guide sign, the place name of the guide sign, the contents of the sign such as an arrow sign, and the position in the guide sign where the sign contents are described are specified.
　案内地点における経路案内が左折である場合、標示情報取得部５１は、左折を示す路面標示を経路案内に関係する道路標示情報とし、直進、右折の路面標示は、経路案内に関係しない道路標示情報に分類する。例えば、案内地点で「三宮」方面に経路案内する場合は、標示情報取得部５１は、案内標識の方面を示す地名として「三宮」と「大阪」を特定していれば、「三宮」を経路案内に関係する道路標示情報とし、「大阪」は、経路案内に関係しない道路標示情報に分類する。 When the route guidance at the guidance point is a left turn, the sign information acquisition unit 51 uses the road marking indicating the left turn as road marking information related to the route guidance, and the road marking information for straight and right turns is the road marking information not related to the route guidance. Classify into: For example, when the route is guided to the direction of “Sannomiya” at the guidance point, the sign information acquisition unit 51 specifies “Sannomiya” and “Osaka” as the place names indicating the direction of the guidance sign, and routes “Sannomiya”. The road marking information related to the guidance is used, and “Osaka” is classified as road marking information not related to the route guidance.
　表示情報生成部５２は、経路案内に関係する道路標示情報を、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示させるための表示情報を生成する。
　例えば、経路案内に関係する道路標示情報が、案内標識の方面および方向の情報である場合、表示情報として、方面を示す地名の文字および方向を示す矢印標示がハイライト色で表現された画像データが生成される。
　また、経路案内に関係する道路標示情報が、情報板に表示された「大阪まで３０ｋｍ、渋滞あり、所要時間４０分」という交通情報である場合に、表示情報として、この内容を示す文字がハイライト色で表現された画像データが生成される。 The display information generation unit 52 generates display information for highlighting the road marking information related to the route guidance so as to appear to overlap the corresponding real road marking information in the forward view.
For example, when the road marking information related to the route guidance is information on the direction and direction of the guidance sign, as display information, image data in which the name of the place name indicating the direction and the arrow marking indicating the direction are expressed in highlight color Is generated.
In addition, when the road marking information related to the route guidance is the traffic information “30 km to Osaka, traffic jam, required time 40 minutes” displayed on the information board, the character indicating this content is high as the display information. Image data expressed in light color is generated.
　さらに、経路案内に関係する道路標示情報が路面標示の右左折の矢印標示である場合、この路面標示に重なって見えるように表示させるための表示情報として、右左折の矢印標示がハイライト色で強調表現された画像が生成される。
　このとき、表示情報生成部５２は、運転者の視線と路面とがなす角度に基づいて、運転者から実在の路面の矢印標示に貼り付けてあるように矢印標示の形状を変形させた画像データを生成する。これにより、路面標示の表示情報を、運転者から見て実際の路面標示に近い形状とすることができる。 In addition, when the road marking information related to the route guidance is the left / right turn arrow marking of the road marking, the right / left turn arrow marking is highlighted as display information to be displayed so as to overlap the road marking. An emphasized image is generated.
At this time, the display information generation unit 52 changes the shape of the arrow sign as pasted from the driver to the arrow sign on the actual road surface based on the angle formed by the driver's line of sight and the road surface. Is generated. Thereby, the display information of a road marking can be made into the shape close | similar to an actual road marking seeing from a driver | operator.
　さらに、表示情報生成部５２が、標示情報取得部５１から順次入力される道路標示情報の内容に基づいて、道路標示情報がある位置と自車の距離に応じたサイズおよび形状の道路標示情報の画像データを表示情報として生成する。
　表示情報生成部５２が生成する表示情報は、自車の走行によって道路標示情報の画像のサイズおよび形状が合わなくなり、実際の道路標示情報からずれる可能性がある。
　そこで、道路標示情報がある位置と自車との距離に応じたサイズおよび形状の道路標示情報の画像データを表示情報とすることで、実在の道路標示情報からのずれを軽減することができる。 Further, the display information generation unit 52 generates road marking information having a size and a shape according to the distance between the position where the road marking information is located and the own vehicle based on the contents of the road marking information sequentially input from the marking information acquisition unit 51. Image data is generated as display information.
The display information generated by the display information generation unit 52 may be out of the actual road marking information because the size and shape of the road marking information image do not match due to the traveling of the vehicle.
Therefore, by using the image data of road marking information having a size and shape according to the distance between the position where the road marking information is present and the own vehicle as display information, deviation from the actual road marking information can be reduced.
　出力制御部５３は、ＨＵＤ７に対して表示情報を出力する。
　なお、ＨＵＤ７は、表示源とこの表示源からの表示光をフロントウィンドウに投影するレンズとの距離を調整することで、このレンズの焦点距離との関係から虚像を任意の距離に結像させることができる。
　例えば、ＨＵＤ７の表示源とレンズとの距離を調整することによって、経路案内に関係する道路標示情報を、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示することができる。
　出力制御部５３は、自車の走行に合わせて表示情報の表示位置を変更することにより、ＨＵＤ７における表示情報の表示を自車の移動に追従させる。 The output control unit 53 outputs display information to the HUD 7.
The HUD 7 adjusts the distance between the display source and the lens that projects the display light from the display source onto the front window, thereby forming a virtual image at an arbitrary distance from the relationship with the focal length of the lens. Can do.
For example, by adjusting the distance between the display source of the HUD 7 and the lens, it is possible to highlight the road marking information related to the route guidance so that it appears to overlap the corresponding real road marking information in the forward view.
The output control unit 53 changes the display position of the display information in accordance with the traveling of the host vehicle, thereby causing the display information display on the HUD 7 to follow the movement of the host vehicle.

　次に動作について説明する。
　図５は、実施の形態１に係るナビゲーション装置の動作を示すフローチャートである。
　図５において、ステップＳＴ１ａからステップＳＴ３ａ、ステップＳＴ９ａの処理は、ナビゲーション処理部５０の動作である。また、ステップＳＴ４ａからステップＳＴ６ａの処理は、図４に示したステップＳＴ１の詳細な処理の一例である。また、ステップＳＴ７ａの処理は、図４に示したステップＳＴ２の詳細な処理の一例であって、ステップＳＴ８ａの処理は、図４に示したステップＳＴ３の詳細な処理の一例である。
　従って、図４の各ステップの動作は、図５の各ステップを説明することにより明らかになるため、以下、図５に基づいて説明を行う。 Next, the operation will be described.
FIG. 5 is a flowchart showing the operation of the navigation device according to the first embodiment.
In FIG. 5, processing from step ST <b> 1 a to step ST <b> 3 a and step ST <b> 9 a is an operation of the navigation processing unit 50. Further, the processing from step ST4a to step ST6a is an example of detailed processing of step ST1 shown in FIG. Moreover, the process of step ST7a is an example of the detailed process of step ST2 shown in FIG. 4, and the process of step ST8a is an example of the detailed process of step ST3 shown in FIG.
Therefore, the operation of each step in FIG. 4 becomes clear by explaining each step in FIG. 5, and will be described below with reference to FIG.
　ナビゲーション処理部５０は、システムが起動すると（ステップＳＴ１ａ）、目的地が設定されているか否かを確認する（ステップＳＴ２ａ）。
　目的地が設定されていない場合（ステップＳＴ２ａ；ＮＯ）、目的地が設定されるまでステップＳＴ２ａに戻って上記確認を繰り返す。
　一方、目的地が設定されていれば（ステップＳＴ２ａ；ＹＥＳ）、ナビゲーション処理部５０は、この目的地までの経路を探索して経路案内を開始する（ステップＳＴ３ａ）。
　例えば、ナビゲーション処理部５０は、位置測定部２によって測定された自車の現在位置を出発地とし、操作部４で入力された目的地および地図データ格納部３から読み出した地図データに基づいて、出発地から目的地までの経路を探索する。
　そして、ナビゲーション処理部５０は、探索結果の経路候補のうち、ユーザに選択された経路の経路案内を開始する。 When the system is activated (step ST1a), the navigation processing unit 50 checks whether a destination is set (step ST2a).
If the destination is not set (step ST2a; NO), the process returns to step ST2a and repeats the above confirmation until the destination is set.
On the other hand, if the destination is set (step ST2a; YES), the navigation processing unit 50 searches for a route to the destination and starts route guidance (step ST3a).
For example, the navigation processing unit 50 uses the current position of the host vehicle measured by the position measurement unit 2 as a departure point, and based on the destination inputted by the operation unit 4 and the map data read from the map data storage unit 3, Search for the route from the starting point to the destination.
Then, the navigation processing unit 50 starts route guidance for the route selected by the user among the route candidates of the search result.
　次に、標示情報取得部５１が、距離測定部８により自車前方で検出された道路標示情報と自車との距離を取得する（ステップＳＴ４ａ）。例えば、案内標識、路面標示、情報板といった標示物と自車との距離が取得される。
　続いて、標示情報取得部５１は道路標示情報の内容を判別する（ステップＳＴ５ａ）。
　例えば、標示情報取得部５１は、撮像部９から得られた画像データを画像解析して道路標示情報の内容を判別する。道路標示情報が案内標識である場合、案内標識に記載される地名、矢印標示などの標示内容およびこの標示内容が記載されている案内標識中の位置が判別される。道路標示情報が路面標示の場合、路面標示である、車線の直進、右左折などの進行方向別の通行区分を示す矢印標示が判別される。道路標示情報が情報板の表示内容である場合、情報板が表示する「大阪まで３０ｋｍ、渋滞あり、所要時間４０分」といった交通情報の内容が判別される。
　この後、標示情報取得部５１は、ステップＳＴ５ａで判別した道路標示情報の内容と、走行予定経路の経路案内情報とを比較して、経路案内に関係する道路標示情報を抽出する（ステップＳＴ６ａ）。 Next, the marking information acquisition unit 51 acquires the distance between the road marking information detected in front of the host vehicle by the distance measuring unit 8 and the host vehicle (step ST4a). For example, the distance between the sign such as a guide sign, road marking, and information board and the vehicle is acquired.
Subsequently, the sign information acquisition unit 51 determines the content of the road sign information (step ST5a).
For example, the sign information acquisition unit 51 performs image analysis on the image data obtained from the imaging unit 9 and determines the content of the road sign information. When the road marking information is a guide sign, the name of the place described on the guide sign, the contents of the sign such as an arrow sign, and the position in the guide sign where the contents of the sign are described are determined. When the road marking information is a road marking, an arrow marking indicating a traffic classification according to the traveling direction, such as a straight lane or a left / right turn, is determined. When the road marking information is the information displayed on the information board, the contents of traffic information such as “30 km to Osaka, traffic jam, required time 40 minutes” displayed on the information board are determined.
Thereafter, the sign information acquisition unit 51 compares the contents of the road sign information determined in step ST5a with the route guidance information of the planned travel route, and extracts road sign information related to the route guidance (step ST6a). .
　次に、表示情報生成部５２は、経路案内に関係する道路標示情報を、ハイライト色で、かつこの経路案内に対応する実在の標示物に合った形態で表現した表示情報を生成する（ステップＳＴ７ａ）。この表示情報は、経路案内に関係する道路標示情報を、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示させるための表示情報である。
　続いて、出力制御部５３は、表示情報生成部５２により生成された表示情報をＨＵＤ７に出力する。これにより、ＨＵＤ７によって、表示情報は、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示される（ステップＳＴ８ａ）。 Next, the display information generation unit 52 generates display information that expresses the road marking information related to the route guidance in a highlight color and in a form suitable for the actual marking corresponding to the route guidance (step ST7a). This display information is display information for highlighting the road marking information related to the route guidance so as to appear to overlap the corresponding actual road marking information in the forward view.
Subsequently, the output control unit 53 outputs the display information generated by the display information generation unit 52 to the HUD 7. As a result, the display information is highlighted by the HUD 7 so as to overlap the corresponding real road marking information in the front view (step ST8a).
　ナビゲーション処理部５０は、出力制御部５３によって表示情報がＨＵＤ７に強調表示されると、経路案内が終了したか否かを確認する（ステップＳＴ９ａ）。経路案内が終了したと判定された場合（ステップＳＴ９ａ；ＹＥＳ）、ステップＳＴ２ａの処理に戻る。また、経路案内が終了していないと判定された場合（ステップＳＴ９ａ；ＮＯ）、ステップＳＴ４ａの処理に戻る。 When the display information is highlighted on the HUD 7 by the output control unit 53, the navigation processing unit 50 checks whether or not the route guidance is finished (step ST9a). If it is determined that the route guidance has been completed (step ST9a; YES), the process returns to step ST2a. Moreover, when it determines with route guidance not being complete | finished (step ST9a; NO), it returns to the process of step ST4a.
　次に、ＨＵＤ７における表示情報の表示について説明する。
　図６は、道路標示情報の表示情報が表示されたフロントウィンドウ越しに見た車両前方の風景を示す図であり、交差点に自車が差し掛かるときの自車前方の状態を示している。図６に示す交差点には、案内標識１０が近傍に配置され、自車が走行する路面に右折矢印１１、直進矢印１２が標示されている。
　ここで、経路案内に関係する道路標示情報が、案内標識の方面「三宮」および右方向を示す情報である場合、表示情報生成部５２は、方面を示す「三宮」の文字と右方向を示す矢印標示にハイライト色を施した画像データを表示情報１０ａとして生成する。
　また、表示情報生成部５２は、実在の右折矢印１１に合った形状にハイライト色を施した画像データを表示情報１１ａとして生成する。 Next, display of display information on the HUD 7 will be described.
FIG. 6 is a diagram showing a landscape in front of the vehicle viewed through the front window on which the display information of the road marking information is displayed, and shows a state in front of the vehicle when the vehicle approaches the intersection. At the intersection shown in FIG. 6, a guide sign 10 is arranged in the vicinity, and a right turn arrow 11 and a straight arrow 12 are marked on the road surface on which the vehicle travels.
Here, when the road marking information related to the route guidance is information indicating the direction “Sannomiya” and the right direction of the guidance sign, the display information generation unit 52 indicates the character “Sannomiya” indicating the direction and the right direction. Image data in which an arrow mark is highlighted is generated as display information 10a.
In addition, the display information generation unit 52 generates, as display information 11a, image data obtained by applying a highlight color to a shape that matches the actual right turn arrow 11.
　出力制御部５３は、ＨＵＤ７に対して表示情報生成部５２により生成された表示情報１０ａ，１１ａを出力する。これにより、ＨＵＤ７によって、表示情報１０ａ，１１ａが、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示される。
　例えば、表示情報１０ａは、実在の案内標識１０の対応する方面および方向が記載された位置に貼り付けてあるように表示される。また、表示情報１１ａは、対応する実在の右折矢印１１に貼り付けてあるように表示される。 The output control unit 53 outputs the display information 10a and 11a generated by the display information generation unit 52 to the HUD 7. As a result, the display information 10a and 11a are highlighted by the HUD 7 so that they appear to overlap the corresponding actual road marking information in the forward view.
For example, the display information 10a is displayed as pasted at a position where the corresponding direction and direction of the actual guide sign 10 are described. The display information 11a is displayed as pasted on the corresponding actual right turn arrow 11.
　なお、強調表示としてハイライト色で表示する場合を示したが、これに限定されるものではない。例えば、経路案内に関係する道路標示情報の表示情報を、ハイライト色で表現する他に、色の点滅、赤色などの警告色で表現、画像形状に縁取りを設けるなど、運転者が気付きやすい形態であればよい。
　ただし、この発明の表示情報は、経路案内に関係する実在の道路標示情報を、ＨＵＤ７において自然な形で強調するものである。従って、この表示情報の形状およびサイズは、運転者から見て実在の道路標示情報の標示物から逸脱しない範囲とする。 In addition, although the case where it displayed by highlight color as an emphasis display was shown, it is not limited to this. For example, in addition to expressing the display information of road marking information related to route guidance in highlight colors, it is expressed in blinking colors, warning colors such as red, and the image shape has a border, etc. If it is.
However, the display information of the present invention emphasizes the actual road marking information related to the route guidance in a natural manner in the HUD 7. Therefore, the shape and size of the display information are within a range that does not deviate from the sign of the actual road sign information as viewed from the driver.
　以上のように、実施の形態１に係る表示制御装置では、経路案内に関係する道路標示情報を強調表示させるための表示情報が、前方視界の対応する実在の道路標示情報に重なって見えるように強調表示される。これにより経路案内に関係する道路標示情報を見やすく表示することができる。 As described above, in the display control apparatus according to the first embodiment, the display information for highlighting the road marking information related to the route guidance seems to overlap the corresponding real road marking information in the forward view. Highlighted. Thereby, it is possible to display the road marking information related to the route guidance in an easy-to-see manner.
実施の形態２．
　図７は、この発明の実施の形態２に係る表示制御装置の機能構成を示すブロック図であり、実施の形態２に係る表示制御装置の機能となる制御部５Ａの機能を示している。図７に示すように、制御部５Ａは、ナビゲーション処理を行う機能としてナビゲーション処理部５０を備え、ＨＵＤ７の表示を制御する機能として標示情報取得部５１、表示情報生成部５２ａ、出力制御部５３ａを備える。なお、図７において、図２と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。 Embodiment 2. FIG.
FIG. 7 is a block diagram showing the functional configuration of the display control apparatus according to Embodiment 2 of the present invention, and shows the function of the control unit 5A that is the function of the display control apparatus according to Embodiment 2. As shown in FIG. 7, the control unit 5A includes a navigation processing unit 50 as a function for performing navigation processing, and includes a labeling information acquisition unit 51, a display information generation unit 52a, and an output control unit 53a as functions for controlling the display of the HUD 7. Prepare. In FIG. 7, the same components as those in FIG.
　表示情報生成部５２ａは、経路案内情報を前方視界の実在の路面エリアに貼り付けてあるように表示させるための表示情報を生成する。
　例えば、現在位置から５０ｍ直進すると三田市三輪の交差点であることを経路案内する場合、この経路案内の内容を文字で表現した画像が表示情報として生成される。
　また、表示情報生成部５２ａは、経路案内情報を前方視界の実在の標示物に隣接して見えるように表示させるための表示情報を生成する。 The display information generation unit 52a generates display information for displaying the route guidance information as if pasted on the actual road surface area of the forward view.
For example, when route guidance is made that the intersection of Mita City Miwa is 50 m straight from the current position, an image expressing the contents of this route guidance in characters is generated as display information.
In addition, the display information generation unit 52a generates display information for displaying the route guidance information so as to be seen adjacent to the actual sign object in the forward field of view.
　出力制御部５３ａは、ＨＵＤ７に対して、表示情報生成部５２ａにより生成された表示情報を出力する。これにより、表示情報は、前方視界の路面エリアに貼り付けてあるように表示されるか、あるいは、前方視界の標示物に隣接して見えるように表示される。 The output control unit 53a outputs the display information generated by the display information generation unit 52a to the HUD 7. Accordingly, the display information is displayed as being pasted on the road surface area of the front view, or is displayed so as to be seen adjacent to the sign object of the front view.
　次に動作について説明する。
　図８は、実施の形態２に係る表示制御装置の詳細な動作を示すフローチャートである。
　図８において、ステップＳＴ１ｂからステップＳＴ２ｂの処理は、図４に示したステップＳＴ１の詳細な処理の一例である。ステップＳＴ３ｂの処理は、図４に示したステップＳＴ２の詳細な処理の一例であり、ステップＳＴ４ｂの処理は、図４に示したステップＳＴ３の詳細な処理の一例である。
　従って、図４の各ステップの動作は、図８の各ステップを説明することにより明らかになるため、以下、図８に基づいて説明を行う。 Next, the operation will be described.
FIG. 8 is a flowchart showing a detailed operation of the display control apparatus according to the second embodiment.
In FIG. 8, the processing from step ST1b to step ST2b is an example of detailed processing of step ST1 shown in FIG. The process of step ST3b is an example of the detailed process of step ST2 shown in FIG. 4, and the process of step ST4b is an example of the detailed process of step ST3 shown in FIG.
Therefore, since the operation of each step in FIG. 4 becomes clear by explaining each step in FIG. 8, a description will be given below based on FIG.
　まず、標示情報取得部５１は、撮像部９により得られた自車前方の撮像情報を画像解析して自車前方の路面エリアを判別する（ステップＳＴ１ｂ）。
　例えば、前方車両および道路脇の地物などが撮像されている部分の輝度値変化が、路面エリアおよび空エリアが撮像されている部分の輝度値変化よりも大きいと仮定して、自車前方の撮像情報から、路面エリアと空エリアが撮像されている部分を判別する。そして、撮像情報におけるエリアの位置に基づいて上方のエリアを空エリアとし、下方のエリアが路面エリアであると判別する。 First, the sign information acquisition unit 51 performs image analysis on the imaging information in front of the host vehicle obtained by the imaging unit 9, and determines the road surface area in front of the host vehicle (step ST1b).
For example, assuming that the change in the luminance value of the part where the vehicle ahead and the features on the road are imaged is larger than the change in the luminance value of the part where the road surface area and the sky area are imaged, A part where the road surface area and the sky area are imaged is determined from the imaging information. Then, based on the position of the area in the imaging information, the upper area is determined to be an empty area, and the lower area is determined to be a road surface area.
　次に、標示情報取得部５１は、ナビゲーション処理部５０から入力した経路案内情報を参照して、自車の現在位置における経路案内情報を路面エリアに表示すべき経路案内情報として抽出する（ステップＳＴ２ｂ）。例えば、現在位置から５０ｍ直進すると、三田市三輪の交差点であることを経路案内する場合、この経路案内の内容が、上記交差点までの路面エリアに表示すべき情報として抽出される。 Next, the sign information acquisition unit 51 refers to the route guidance information input from the navigation processing unit 50 and extracts the route guidance information at the current position of the host vehicle as the route guidance information to be displayed in the road surface area (step ST2b). ). For example, when traveling straight 50 meters from the current position, when route guidance is made at the intersection of Mita City Miwa, the content of this route guidance is extracted as information to be displayed in the road surface area up to the intersection.
　表示情報生成部５２ａは、標示情報取得部５１により抽出された経路案内情報を、前方視界の実在の路面エリアに貼り付けてあるように表示させるための表示情報を生成する（ステップＳＴ３ｂ）。この後、出力制御部５３ａは、ＨＵＤ７に対して上記表示情報を出力する。これにより、上記表示情報は、前方視界の実在の路面エリアに貼り付けてあるように表示される（ステップＳＴ４ｂ）。 The display information generation unit 52a generates display information for displaying the route guidance information extracted by the sign information acquisition unit 51 so as to be pasted on the actual road surface area of the front view (step ST3b). Thereafter, the output control unit 53a outputs the display information to the HUD 7. Thereby, the display information is displayed as pasted on the actual road surface area of the front view (step ST4b).
　図９は、経路案内情報の表示情報が表示されたフロントウィンドウ越しに見た車両前方の風景を示す図であり、交差点に自車が差し掛かるときの自車前方の状態を示している。
　ここで、現在位置から５０ｍ直進すると三田市三輪の交差点であることを経路案内する場合、表示情報生成部５２ａは、この経路案内の内容を文字で表現した画像データを表示情報１４として生成する。 FIG. 9 is a diagram showing a scenery in front of the vehicle viewed through the front window on which the display information of the route guidance information is displayed, and shows a state in front of the own vehicle when the own vehicle approaches the intersection.
Here, in the case where route guidance is made that it is an intersection of Mita City Miwa if it goes straight 50 m from the current position, the display information generation unit 52 a generates image data that expresses the contents of this route guidance as characters as display information 14.
　出力制御部５３ａは、ＨＵＤ７に対して、表示情報生成部５２ａにより生成された表示情報１４を出力する。これにより、ＨＵＤ７によって、図９に示すように、表示情報１４は、前方視界の実在の路面エリア１３に貼り付けてあるように表示される。
　このようにして、路面上の車両などを運転者が認識するときの邪魔にならないように、経路案内情報を表示することができる。 The output control unit 53a outputs the display information 14 generated by the display information generation unit 52a to the HUD 7. Thereby, as shown in FIG. 9, the display information 14 is displayed by the HUD 7 as pasted on the actual road surface area 13 in the forward field of view.
In this way, route guidance information can be displayed so as not to obstruct the driver when recognizing a vehicle or the like on the road surface.
　図１０は、実施の形態２に係る表示制御装置の別の動作を示すフローチャートであり、経路案内情報の表示情報を表示する方法が図８とは異なる。
　図１０において、ステップＳＴ１ｃからステップＳＴ２ｃの処理は、図４に示したステップＳＴ１の詳細な処理の一例である。ステップＳＴ３ｃの処理は、図４に示したステップＳＴ２の詳細な処理の一例であり、ステップＳＴ４ｃの処理は、図４に示したステップＳＴ３の詳細な処理の一例である。
　従って、図４の各ステップの動作は、図１０の各ステップを説明することにより明らかになるため、以下、図１０に基づいて説明を行う。 FIG. 10 is a flowchart showing another operation of the display control apparatus according to the second embodiment, and the method for displaying the display information of the route guidance information is different from FIG.
In FIG. 10, the processing from step ST1c to step ST2c is an example of detailed processing of step ST1 shown in FIG. The process of step ST3c is an example of the detailed process of step ST2 shown in FIG. 4, and the process of step ST4c is an example of the detailed process of step ST3 shown in FIG.
Therefore, the operation of each step in FIG. 4 becomes clear by explaining each step in FIG. 10, and will be described below based on FIG. 10.
　標示情報取得部５１は、上記と同様にして、撮像部９により得られた自車前方の撮像情報を画像解析して自車前方の路面エリアを判別する（ステップＳＴ１ｃ）。
　次に、標示情報取得部５１は、ナビゲーション処理部５０から入力した経路案内情報を参照して、自車の現在位置における経路案内情報を標示物に隣接して表示すべき経路案内情報として抽出する（ステップＳＴ２ｃ）。
　例えば、道路標示情報として情報板が検出され、この情報板にない交通情報が得られた場合、この交通情報の内容を、標示物である情報板に隣接して表示すべき経路案内情報として抽出する。 In the same manner as described above, the sign information acquisition unit 51 performs image analysis on the imaging information in front of the host vehicle obtained by the imaging unit 9, and determines the road surface area in front of the host vehicle (step ST1c).
Next, the sign information acquisition unit 51 refers to the route guide information input from the navigation processing unit 50 and extracts the route guide information at the current position of the vehicle as route guide information to be displayed adjacent to the sign object. (Step ST2c).
For example, when an information board is detected as road marking information, and traffic information that is not on this information board is obtained, the contents of this traffic information are extracted as route guidance information to be displayed adjacent to the information board that is a sign object. To do.
　表示情報生成部５２ａは、標示情報取得部５１により抽出された経路案内情報を、前方視界の実在の標示物に隣接して見えるように表示させるための表示情報を生成する（ステップＳＴ３ｃ）。例えば、情報板にない交通情報を示す表示情報が生成される。
　出力制御部５３ａは、ＨＵＤ７に対して上記表示情報を出力する。これにより、ＨＵＤ７によって、表示情報は、前方視界の実在の標示物に隣接した位置に表示される（ステップＳＴ４ｃ）。例えば、情報板にない交通情報の表示情報が、この情報板に隣接するように表示される。
　このようにすることで、運転者は、前方視界における実在の情報板の表示内容と、この情報板に隣接して見える表示情報とから、自車の現在位置における交通情報をまとめて認識することができる。
　これにより、交通情報を得るために運転者が視線を動かす量を軽減でき、運転に注力させることができる。 The display information generation unit 52a generates display information for displaying the route guidance information extracted by the sign information acquisition unit 51 so as to be seen adjacent to the actual sign object in the forward field of view (step ST3c). For example, display information indicating traffic information that is not on the information board is generated.
The output control unit 53a outputs the display information to the HUD 7. Accordingly, the display information is displayed by the HUD 7 at a position adjacent to the actual sign in the forward field of view (step ST4c). For example, display information of traffic information that is not on the information board is displayed so as to be adjacent to the information board.
In this way, the driver can collectively recognize the traffic information at the current position of the vehicle from the display contents of the actual information board in the forward field of view and the display information that appears adjacent to the information board. Can do.
Thereby, in order to obtain traffic information, the amount of movement of the driver's line of sight can be reduced, and driving can be focused.
　図１１は、別の経路案内情報の表示情報が表示されたフロントウィンドウ越しに見た車両前方の風景を示す図であり、交差点に自車が差し掛かるときの自車前方の状態を示している。この交差点には、案内標識はないが、標示物として信号機１５が配置されている。
　この交差点に自車が差し掛かったとき、「大阪まで３０ｋｍ、渋滞あり４０分」という交通情報が得られた場合、標示情報取得部５１は、この交通情報を標示物に隣接して表示すべき経路案内情報として取得する。
　表示情報生成部５２ａは、経路案内情報の内容を文字で表現した画像データを、前方視界の実在の信号機１５に隣接して見えるように表示させるための表示情報１６として生成する。 FIG. 11 is a diagram showing a landscape in front of the vehicle viewed through the front window on which display information of another route guidance information is displayed, and shows a state in front of the vehicle when the vehicle approaches an intersection. . There is no guide sign at this intersection, but a traffic light 15 is arranged as a sign.
When the vehicle arrives at this intersection and traffic information “30 km to Osaka, 40 minutes with traffic” is obtained, the sign information acquisition unit 51 should display this traffic information adjacent to the sign. Obtained as guide information.
The display information generation unit 52a generates image data expressing the contents of the route guidance information as characters as display information 16 for displaying the image data so as to be seen adjacent to the actual traffic light 15 in the forward field of view.
　次に、出力制御部５３ａは、ＨＵＤ７に対して表示情報１６を出力する。これにより、ＨＵＤ７によって、表示情報１６は、図１１に示すように、前方視界の信号機１５に隣接して見えるように表示される。
　このように車両の運転中に自然に運転者の目が向く信号機１５などの標示物に隣接させて経路案内情報を表示することで、車両の運転の邪魔にならずに経路案内情報を的確に伝えることができる。 Next, the output control unit 53a outputs the display information 16 to the HUD 7. Accordingly, the display information 16 is displayed by the HUD 7 so as to be seen adjacent to the traffic light 15 in the front field of view as shown in FIG.
Thus, by displaying the route guidance information adjacent to the sign such as the traffic light 15 that the driver's eyes naturally face while driving the vehicle, the route guidance information can be accurately obtained without obstructing the driving of the vehicle. I can tell you.
　以上のように、実施の形態２に係る表示制御装置において、表示情報生成部５２ａは、経路案内情報を前方視界の実在の路面エリア１３に貼り付けてあるように表示させるための表示情報１４を生成する。これにより、路面上の車両などを運転者が認識するときの邪魔にならないように、経路案内情報をＨＵＤ７に表示できる。
　また、表示情報生成部５２ａは、経路案内情報を前方視界の実在の信号機１５に隣接して見えるように表示させるための表示情報１６を生成する。
　このように車両の運転中に自然に運転者の目が向く標示物に隣接させて経路案内情報を表示することで、車両の運転の邪魔にならずに経路案内情報を的確に伝えることができる。
　また、経路案内情報を、これに関係する標示物に隣接させて表示することで、関係する経路案内情報をまとめて運転者に示すことができる。 As described above, in the display control apparatus according to the second embodiment, the display information generation unit 52a displays the display information 14 for displaying the route guidance information as if pasted on the actual road surface area 13 in the forward field of view. Generate. Thereby, route guidance information can be displayed on the HUD 7 so as not to obstruct the driver when recognizing a vehicle or the like on the road surface.
In addition, the display information generation unit 52a generates display information 16 for displaying the route guidance information so as to be seen adjacent to the actual traffic light 15 in the forward field of view.
In this way, by displaying the route guidance information adjacent to the sign that the driver's eyes naturally face while driving the vehicle, the route guidance information can be accurately transmitted without obstructing the driving of the vehicle. .
In addition, by displaying the route guidance information adjacent to the sign related to the route guidance information, the related route guidance information can be collectively shown to the driver.

　図１２は、この発明の実施の形態３に係る表示制御装置の機能構成を示すブロック図であり、実施の形態３に係る表示制御装置の機能となる制御部５Ｂの機能を示している。
　図１２に示すように、制御部５Ｂは、ナビゲーション処理を行う機能としてナビゲーション処理部５０を備え、ＨＵＤ７の表示を制御する機能として標示情報取得部５１、表示情報生成部５２ｂ、出力制御部５３ｂを備える。なお、図１２において図２と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。 Embodiment 3 FIG.
FIG. 12 is a block diagram showing the functional configuration of the display control apparatus according to Embodiment 3 of the present invention, and shows the function of the control unit 5B, which is the function of the display control apparatus according to Embodiment 3.
As shown in FIG. 12, the control unit 5B includes a navigation processing unit 50 as a function for performing navigation processing, and includes a labeling information acquisition unit 51, a display information generation unit 52b, and an output control unit 53b as functions for controlling display of the HUD 7. Prepare. In FIG. 12, the same components as those in FIG.
　表示情報生成部５２ｂは、前方視界の車両運転に関係しないエリアをマスク表示させるためのマスク用表示情報を生成する。
　マスク用表示情報としては、例えば、重ねて表示した下地の内容が半透明もしくは遮蔽される画像情報が挙げられる。また、図１４で後述するように、街路樹画像を、マスク用表示情報として生成してもよい。 The display information generation unit 52b generates mask display information for mask-displaying an area that is not related to vehicle driving in the forward view.
As the display information for mask, for example, image information in which the content of the background displayed in an overlapping manner is translucent or shielded can be cited. Further, as will be described later with reference to FIG. 14, a street tree image may be generated as mask display information.
　出力制御部５３ｂは、ＨＵＤ７に対してマスク用表示情報を出力する。これにより、ＨＵＤ７によって、マスク用表示情報は、前方視界の車両運転に関係しないエリアに表示される。なお、車両運転に関係しないエリアは、運転者が視認しなくても車両の運転に支障を来さない視界内のエリアである。例えば、高速道路の道路脇の風景などは、運転者が視認しなくても運転に支障がない。そこで、実施の形態３では、高速道路の道路脇の風景にマスク用表示情報が重なって見えるように表示される。 The output control unit 53b outputs mask display information to the HUD 7. Thereby, the display information for mask is displayed by the HUD 7 in an area not related to the vehicle driving in the forward field of view. The area not related to vehicle driving is an area in the field of view that does not hinder the driving of the vehicle even if the driver does not visually recognize it. For example, a roadside scenery of an expressway does not hinder driving even if the driver does not visually recognize it. Therefore, in the third embodiment, the display information for the mask is displayed so as to overlap the scenery on the roadside of the expressway.
　次に動作について説明する。
　図１３は実施の形態３に係る表示制御装置の詳細な動作を示すフローチャートである。

　また、図１４は、マスク用表示情報が表示されたフロントウィンドウ越しに見た車両前方の風景を示す図である。 Next, the operation will be described.
FIG. 13 is a flowchart showing a detailed operation of the display control apparatus according to the third embodiment.
In FIG. 13, the process of step ST1d is an example of the detailed process of step ST1 shown in FIG. The process of step ST2d is an example of the detailed process of step ST2 shown in FIG. 4, and the process of step ST3d is an example of the detailed process of step ST3 shown in FIG. Therefore, the operation of each step in FIG. 4 becomes clear by explaining each step in FIG. 13, and will be described below with reference to FIG.
FIG. 14 is a diagram showing a scenery in front of the vehicle viewed through the front window on which the mask display information is displayed.
　標示情報取得部５１は、実施の形態２と同様に、撮像部９によって得られた自車前方の撮像情報を画像解析して自車前方の路面エリア１３を判別する（ステップＳＴ１ｄ）。
　次に、表示情報生成部５２ｂは、前方視界の路面エリア１３の左右両端に沿った位置にマスク表示させるためのマスク用表示情報１７を生成する（ステップＳＴ２ｄ）。図１４の例では、マスク用表示情報１７は、街路樹の画像になっている。 As in the second embodiment, the sign information acquisition unit 51 performs image analysis on the imaging information in front of the host vehicle obtained by the imaging unit 9, and determines the road surface area 13 in front of the host vehicle (step ST1d).
Next, the display information generation unit 52b generates mask display information 17 for mask display at positions along the left and right ends of the road surface area 13 in the forward view (step ST2d). In the example of FIG. 14, the mask display information 17 is an image of a roadside tree.
　この後、出力制御部５３ｂは、ＨＵＤ７に対してマスク用表示情報１７を出力する。
　これにより、ＨＵＤ７によって、マスク用表示情報１７は、前方視界の路面エリア１３の左右両端に沿った位置に表示される（ステップＳＴ３ｄ）。これにより、運転者からは、街路樹が仮想的に表示された道路を自車が走行しているように見える。 Thereafter, the output control unit 53b outputs the mask display information 17 to the HUD 7.
Accordingly, the mask display information 17 is displayed by the HUD 7 at positions along the left and right ends of the road surface area 13 in the forward field of view (step ST3d). As a result, it appears to the driver that the vehicle is traveling on the road on which the roadside tree is virtually displayed.
　以上のように、実施の形態３に係る表示制御装置において、表示情報生成部５２ｂは、前方視界の車両運転に関係しないエリアをマスク表示させるためのマスク用表示情報１７を生成する。このように、運転者の視界内の運転に関係しないエリアをマスク用表示情報１７で遮ることで、運転者の脇見運転を防止することができる。 As described above, in the display control apparatus according to the third embodiment, the display information generation unit 52b generates the mask display information 17 for mask-displaying an area that is not related to the vehicle driving in the forward view. In this way, by blocking areas not related to driving in the driver's field of view with the mask display information 17, the driver's side-by-side driving can be prevented.
