Abstract

<P>PROBLEM TO BE SOLVED: To provide an inexpensive driving simulator capable of displaying a clear image on a large screen. <P>SOLUTION: A projector 103 displays the peripheral part of a scene, and a projector 104 displays the center part of the scene by combining it with the peripheral part. Since the viewing angle of the projector 104 is smaller than that of the projector 103, the resolution of the center part is higher than that of the peripheral part even when the number of pixels of the two projectors is the same. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、自動車の運転及び走行を模擬する自動車運転模擬装置に関する。   The present invention relates to an automobile driving simulation device that simulates driving and running of an automobile.

自動車の運転・走行の教育・訓練および研究のために、運転及び走行を模擬する自動車運転模擬装置が用いられる。
自動車運転模擬装置は、運転者が模擬の運転席に搭乗し、そのアクセル、ブレーキ、ハンドル等の操作から自動車の運動を計算し、また一方道路や市街地といった景観データベースが設けられ、この運動の結果から運転席から見える景観の変化を計算し、表示装置上に映し出すものである。表示装置はブラウン管や液晶表示があるが、大規模な画面の要求に対しては、プロジェクタでスクリーン上に表示するものが用いられる。 An automobile driving simulation device that simulates driving and driving is used for education / training and research of driving and driving of automobiles.
A car driving simulation device is used to calculate the movement of a car from the driver, boarding a simulated driver's seat, and operating the accelerator, brakes, steering wheel, etc. The change of the scenery seen from the driver's seat is calculated and displayed on the display device. The display device includes a cathode ray tube and a liquid crystal display, but in order to meet a demand for a large-scale screen, a device that displays on a screen with a projector is used.

プロジェクタで景観を映し出す場合、全表示画面で鮮明な画像を実現するためには、高解像度のプロジェクタを用いて画面いっぱいに映像を投影する必要がある。しかしながらこういった高解像度のプロジェクタは高価であるばかりではなく、大型になるため、設置が困難になる。また、表示のための画素の数が増えてそのための計算処理に時間を要し、装置の計算速度の能力から、計算処理の単位時間きざみ幅（イタレーションタイム）内で処理が終わらないといった性能上の課題がある。   When projecting a landscape with a projector, it is necessary to project an image to the full screen using a high-resolution projector in order to realize a clear image on the entire display screen. However, such a high-resolution projector is not only expensive, but also becomes large and difficult to install. In addition, the number of pixels for display increases and time is required for the calculation process, and the performance of the apparatus does not end within the unit time increment (iteration time) of the calculation process due to the calculation speed capability of the device. There is an upper problem.

本発明の目的は、上記課題を解決し、人間工学の観点から運転者が運転に支障がない映像を実現し、運転・走行の教育・訓練および研究に効果的に使用できる自動車運転模擬装置を得ることにある。   An object of the present invention is to provide an automobile driving simulation device that solves the above-described problems, realizes an image that does not hinder driving from the viewpoint of ergonomics, and can be effectively used for education / training and research of driving / driving. There is to get.

上記の目的は、運転者の操作に基づき、運転者が模擬的に運転する乗物の模擬的な運動を計算する運動計算手段と、運動計算手段の計算結果に基づき、運転席から見えることになる景観を計算する景観計算手段と、景観計算手段が計算した景観のうち、その周辺部分の画像を表示する第１の画像表示手段と、景観計算手段が計算した景観のうち、その中央部分の画像を、第１の画像表示手段による画像の分解能よりも高い分解能で、第１の画像表示手段が表示する画像に合成して表示する第２の画像表示手段とを具備する運転模擬装置により達成される。
例えば、前記第１の画像表示手段および前記第２の画像表示手段はそれぞれ、同一のスクリーンに画像を投影する第１および第２のプロジェクタを含み、第２のプロジェクタの画角は第１のプロジェクタの画角よりも小さく、それによって、前記高い分解能を実現する。 The above purpose is to be seen from the driver's seat based on the calculation result of the motion calculation means and the motion calculation means for calculating the simulated motion of the vehicle that the driver drives based on the driver's operation. The landscape calculation means for calculating the landscape, the first image display means for displaying an image of the peripheral portion of the landscape calculated by the landscape calculation means, and the image of the central portion of the landscape calculated by the landscape calculation means Is achieved by a driving simulation apparatus comprising: a second image display means for combining and displaying an image displayed by the first image display means with a resolution higher than the resolution of the image by the first image display means. The
For example, each of the first image display means and the second image display means includes first and second projectors that project an image on the same screen, and the angle of view of the second projector is the first projector. Smaller than the angle of view, thereby realizing the high resolution.

運転者が運転模擬装置を操作するとき、その前面の表示装置には乗物の運動計算の結果として景観の変化が映し出されるが、必ずしも表示装置全面にわたって鮮明な画像である必要はない。というのも、円滑かつ安全な走行や確実な危険予知のためには、運転者の視線は乗物の進行方向とその周囲に集中し、遠くのものを見るための分解能は高くなくてはならない（中心視野）。景観の周辺部分は視線の集中度は低く、分解能はそれほど高くなくても良い（周辺視野）。本発明の運転模擬装置では、表示の中央部分の分解能が高いので、周辺部分が中央部分に比べて粗い分解能の表示であっても、運転模擬装置の動作上支障はない。   When the driver operates the driving simulation device, a change in the landscape is displayed on the front display device as a result of the motion calculation of the vehicle, but it is not always necessary to have a clear image over the entire display device. This is because, for smooth and safe driving and reliable danger prediction, the driver's line of sight must be concentrated in and around the direction of travel of the vehicle, and the resolution to see far away must be high ( Central vision). The peripheral part of the landscape has a low gaze concentration and the resolution does not have to be very high (peripheral vision). In the driving simulation apparatus of the present invention, since the resolution of the central portion of the display is high, even if the peripheral portion is a display with a coarser resolution than the central portion, there is no problem in the operation of the driving simulation device.

図１は本発明の一実施形態に係る自動車運転模擬装置の構成を示す。図１において、模擬自動車運転席１０１にはアクセル、ブレーキ、ハンドル等が備えられている。運転席１０１に搭乗した運転者が運転席１０１に備えられたアクセル、ブレーキ、ハンドル等を操作すると、それに応じた信号が計算手段１０５へ入力される。計算手段１０５は例えばコンピュータにより実現される。計算手段１０５においては、アクセル、ブレーキ、ハンドル等の操作（１０５ａ）に基づく自動車の運動を計算し（１０５ｂ）、景観データベース１０５ｄを参照して、この運動の結果により運転席から見える時々刻々の景観を計算して画像データを生成し（１０５ｃ）、計算により得られた景観をプロジェクタ１０３，１０４によりスクリーン１０２上に映し出す。
プロジェクタ１０３はスクリーン１０２上に景観全体の画像１０２ａを映し出すものであり、その中央部分の投影領域がカットされており周辺部のみを映し出す。プロジェクタ１０４はプロジェクタ１０３の画角よりも小さい画角で中央部の画像１０２ｂを周辺部の画像１０２ａに合成して映し出すものである。
図２に一例を示すように、画像１０２ａおよび画像１０２ｂの縦方向の画素数はいずれも１０２４画素である。しかしながら、画像１０２ｂの縦方向の長さは画像１０２ａの縦方向の長さの１／３以下である。横方向についても同様である。したがって、中央部分の画像１０２ｂの分解能は周辺部分の画像１０２ａの分解能の３倍以上となっている。なお、図２ではプロジェクタ１０４からスクリーンまでの距離をプロジェクタ１０３からスクリーンまでの距離よりも短くすることで高い分解能を実現しているが、図１に示すように、画角を小さくすることでも高い分解能を実現することができる。
本実施形態では、安価な低解像度のプロジェクタで表示装置全面に景観を映し出し、中央部分はこの投影領域からカットしておいて同じ安価な低解像度のプロジェクタで投影し、両プロジェクタの映像を合成する。中央部分の表示エリアが狭く低解像度であっても、分解能はかなり高くなり、遠くの映像を鮮明に映し出すことができる。
自動車の運転模擬装置について本発明を説明してきたが、本発明の性質から模擬の対象は自動車に限るものではなく、２輪自動車や鉄道、航空機といった乗物全般の模擬装置に対しても適用可能である。 FIG. 1 shows the configuration of an automobile driving simulation apparatus according to an embodiment of the present invention. In FIG. 1, a simulated car driver's seat 101 is provided with an accelerator, a brake, a handle, and the like. When a driver who has boarded the driver's seat 101 operates an accelerator, a brake, a handle, or the like provided in the driver's seat 101, a signal corresponding thereto is input to the calculation means 105. The calculation means 105 is realized by a computer, for example. The calculation means 105 calculates the motion of the vehicle based on the operation (105a) of the accelerator, the brake, the steering wheel, etc. (105b), refers to the landscape database 105d, and sees the scenery that can be seen from the driver's seat according to the result of this motion. Is calculated to generate image data (105c), and the landscape obtained by the calculation is displayed on the screen 102 by the projectors 103 and 104.
The projector 103 projects an image 102 a of the entire landscape on the screen 102, and the projection area at the center portion thereof is cut and only the peripheral portion is projected. The projector 104 synthesizes and projects the central image 102 b with the peripheral image 102 a at an angle of view smaller than that of the projector 103.
As shown in FIG. 2, the number of pixels in the vertical direction of the image 102a and the image 102b is 1024 pixels. However, the vertical length of the image 102b is 1/3 or less of the vertical length of the image 102a. The same applies to the horizontal direction. Therefore, the resolution of the central portion image 102b is three times or more the resolution of the peripheral portion image 102a. In FIG. 2, a high resolution is realized by making the distance from the projector 104 to the screen shorter than the distance from the projector 103 to the screen. However, as shown in FIG. Resolution can be realized.
In this embodiment, an inexpensive low-resolution projector projects a landscape on the entire surface of the display device, the central portion is cut from this projection area, projected by the same inexpensive low-resolution projector, and the images of both projectors are combined. . Even if the display area in the central part is narrow and the resolution is low, the resolution is considerably high, and a distant image can be clearly displayed.
Although the present invention has been described with respect to an automobile driving simulation device, the object of simulation is not limited to an automobile due to the nature of the present invention, and it can also be applied to an automobile simulation apparatus such as a two-wheeled vehicle, a railway, and an aircraft. is there.
