Abstract
The infra red vision system comprises at last one IR light source (1) and at least one IR vision system (2) for the representation of a relief which may be illuminated by the IR light source (1). Additionally, an IR detector (3) for the recognition of an extraneous IR impulse (F) is provided.
Description
Beschreibungdescription
Infrarot-SichtsystemInfrared vision system
Die Erfindung betrifft ein Infrarot- ("IR"-) Sichtsystem sowie ein Verfahren zur Blendungsminderung unter Verwendung eines Infrarot-Sichtsystems .The invention relates to an infrared ("IR") vision system and a method for reducing glare using an infrared vision system.
Es sind passive IR-Nachtsichtgeräte bekannt, welche das auch bei Dunkelheit vorhandene Infrarotlicht zur Darstellung eines Umgebungsbildes ("Reliefs") verwenden. Sie arbeiten typischerweise in einem Wellenlängenbereich von ca. 12 um. Deren Nachteile sind u. a. eine geringe Ortsauflösung und, bedingt durch die geringe Strahlungsintensität der Gegenstände des Reliefs, die Verwendung eines vergleichsweise teuren Detektorsystems .Passive IR night vision devices are known which use the infrared light which is present even in the dark to display a surrounding image ("reliefs"). They typically operate in a wavelength range of approximately 12 µm. The disadvantages are u. a. a low spatial resolution and, due to the low radiation intensity of the objects in the relief, the use of a comparatively expensive detector system.
Ebenfalls bekannt sind aktive Infrarot-Nachtsichtgeräte, bei denen das Sichtfeld mit einer eigenen IR-Lichtquelle, typi- sehe Wellenlänge ca. 800 nm, ausgeleuchtet wird. Die Verwendung eines aktiven Systems gegenüber einem passiven System ermöglicht eine höhere Ortsauflösung, eine mögliche Nutzung eines vergleichsweise preiswerten Detektorsystems, und das Detektorsystem, typischerweise eine herkömmliche Videokamera, kann günstigerweise auch hinter Glas, beispielsweise einer Windschutzscheibe, eingesetzt werden.Active infrared night vision devices are also known, in which the field of view is illuminated with its own IR light source, typical wavelength approx. 800 nm. The use of an active system compared to a passive system enables a higher spatial resolution, a possible use of a comparatively inexpensive detector system, and the detector system, typically a conventional video camera, can also advantageously be used behind glass, for example a windshield.
Aus einer Presseveröffentlichung aus dem Internet (www. daimlerchrysler . de/news/top/t00405 e .htm vom 13. April 2000) der DaimlerChrysler AG ist ein aktives IR-Nachtsicht- system bekannt, bei dem zwei an einer Fahrzeugfront angebrachte Laserscheinwerfer eine Straße mit einem für das menschliche Auge unsichtbaren Infrarot-Lichtbündel ausleuchten. Eine Videokamera nimmt das reflektierte Bild der Ξtraßenszene auf und erzeugt daraus eine Schwarz-Weiß-Abbildung. Diese wird auf einem Bildschirm direkt im Blickfeld des Fahrers dargestellt und in einem sogenannten Head-up-Display

De / news / top / t00405 e .htm dated April 13, 2000) from DaimlerChrysler AG, in which two laser headlights mounted on a vehicle front face a street with an infrared light beam that is invisible to the human eye.

Fahrzeuge, bzw. im Extremfall zwei komplett mit diesem IR- Sichtsystem ausgerüstete längere Fahrzeugkolonnen, so pendeln sich die Pulsfrequenzen f der beiden Fahrzeugkolonnen so ein, dass die Pulsfrequenzen f der einzelnen Kolonnen synchron schwingen.Vehicles, or in extreme cases two longer vehicle columns completely equipped with this IR vision system, the pulse frequencies f of the two vehicle columns level off in such a way that the pulse frequencies f of the individual columns oscillate synchronously.
In dem folgenden Ausführungsbeispiel wird das IR-System schematisch näher dargestellt.In the following embodiment, the IR system is shown schematically in more detail.
Figur 1 zeigt dazu skizzenhaft eine IR-Lichtquelle 1, welche IR-Eigenpulse P, deren Ausbreitungsrichtung hier durch Pfeile angedeutet ist, aussendet. Die am Relief, hier durch Objekte 0,0' symbolisiert, reflektierten IR-Eigenpulse P gelangen in ein IR-Sichtgerät 2, welches das IR-Bild an ein Head-up- Display 5 weitergibt. Durch das Head-up-Display 5 kann der Fahrer das IR-Bild der Umgebung im sichtbaren Bereich wahrnehmen.FIG. 1 shows a sketch of an IR light source 1, which emits its own IR pulses P, whose direction of propagation is indicated here by arrows. The IR intrinsic pulses P reflected on the relief, here symbolized by objects 0,0 ', reach an IR viewing device 2, which transmits the IR image to a head-up display 5. The head-up display 5 enables the driver to perceive the IR image of the surroundings in the visible area.
Die IR-Lichtquelle 1 liegt in Form eines IR-Lasers mit einer Wellenlänge des Infrarotlichts von ca. 800 n vor. Das IR- Sichtgerät 2 ist eine infrarot-sensible Videokamera. Zusätzlich ist ein IR-Detektor 3 vorhanden, durch den ein IR- Fremdpuls F, der von einem fremden Kraftfahrzeug 0' ausgesandt wird, detektiert wird. Die Information des IR-Detektors 3 über die fremde Strahlungsquelle wird an eine Steuereinheit 4 weitergeleitet, beispielsweise eine Pulsfrequenz fF, eine Dauer oder eine Stärke der IR-Fremdpulse F. Die Ausbreitungsrichtung der IR-Fremdpulse F ist hier schematisch durch Pfeile dargestellt.The IR light source 1 is in the form of an IR laser with a wavelength of the infrared light of approximately 800 n. The IR viewing device 2 is an infrared-sensitive video camera. In addition, an IR detector 3 is provided, by means of which an external IR pulse F, which is emitted by an external motor vehicle 0 ', is detected. The information from the IR detector 3 about the external radiation source is forwarded to a control unit 4, for example a pulse frequency f F , a duration or a strength of the external IR pulses F. The direction of propagation of the external IR pulses F is shown schematically here by arrows.
Mittels der Steuereinheit 4 wird die Eigen-Pulsfrequenz fP der Fremd-Pulsfrequenz fF angeglichen und mit einem Zeitoffset Δt dergestalt versehen, dass das eigene IR-Sichtsyste S in der Dunkelphase des Fremdsystems aktiv ist.The self-pulse frequency f P is adjusted to the external pulse frequency f F by means of the control unit 4 and is provided with a time offset Δ t such that the own IR vision system S is active in the dark phase of the external system.
Die Steuereinheit 4 kann so eingerichtet bzw. programmiert sein, dass auch die Dauer der IR-Eigenpulse P in Abhängigkeit
eines Fremdstrahlers eingestellt wird. Beispielsweise kann bei Abwesenheit eines IR-Fremdstrahlers die gesamte Zeit das Relief ausgeleuchtet werden und bei Vorhandensein einer oder mehrerer Fremdstrahler die Strahlzeit des eigenen IR-Systems S so eingestellt werden, dass eine maximale Beleuchtungszeit verbleibt.
The control unit 4 can be set up or programmed so that the duration of the IR intrinsic pulses P also depends an external radiator is set. For example, in the absence of an external IR radiator, the entire time can be illuminated, and if one or more external radiators are present, the beam time of the own IR system S can be set so that a maximum illumination time remains.
