Description
Die Erfindung betrifft ein Verfahren zum Überwachen eines Fahrers eines Straßenfahrzeugs zur Vorbeugung von Gefahrensituationen durch ein Auftreten unvorhersehbarer schwerer Erkrankungen, nach der im Oberbegriff von Anspruch 1 näher definierten Art sowie eine Vorrichtung zum Überwachen eines Fahrers nach der im Oberbegriff von Anspruch 5 näher definierten Art.The invention relates to a method for monitoring a driver of a road vehicle for the prevention of dangerous situations by the occurrence of unpredictable serious illnesses, according to the closer defined in the preamble of claim 1 and a device for monitoring a driver according to the closer defined in the preamble of claim 5 Art.
Prinzipiell sind Verfahren oder Vorrichtungen zum Überwachen eines Fahrers eines Straßenfahrzeugs zur Vorbeugung von Gefahrensituationen durch ein Auftreten unvorhersehbarer schwerer Erkrankungen aus dem Stand der Technik bekannt.In principle, methods or devices for monitoring a driver of a road vehicle for the prevention of dangerous situations by the occurrence of unpredictable serious diseases known from the prior art.
So beschreibt beispielsweise die
Schwere Erkrankungen oder gesundheitliche Beeinträchtigungen, die spontan und unvorhersehbar bei einem Fahrer eines Straßenfahrzeugs auftreten, können zu schweren Straßenunfällen führen, da der Fahrer nicht mehr entsprechend reagieren kann, um beispielsweise ein Fahrzeug abzubremsen oder entsprechend zu lenken.
So kann eine gesundheitliche Beeinträchtigung darin bestehen, dass ein Fahrer plötzlich einen Schlaganfall oder eine Hirnblutung erleidet. Derartige schwere Erkrankungen sind in der Regel durch den Fahrer nicht wahrnehmbar und durch einen Arzt nur schwer im Vorhinein erkennbar. So kann die Gefahr derartiger Erkrankungen meist nur erkannt werden, wenn der Patient zuvor bereits starke Beschwerden wie Kopfschmerzen, neurologische Ausfallerscheinungen oder Ähnliches aufweist.Severe illnesses or health impairments that occur spontaneously and unpredictably in a driver of a road vehicle can lead to serious road accidents, since the driver can no longer react accordingly, for example, to brake or steer a vehicle.
So a health impairment can consist in the fact that a driver suddenly suffers a stroke or a cerebral hemorrhage. Such serious illnesses are usually not noticeable by the driver and are difficult to detect in advance by a doctor. Thus, the danger of such diseases can usually only be recognized if the patient has previously had severe symptoms such as headache, neurological deficits or the like.
Die Aufgabe der hier vorliegenden Erfindung besteht nun darin, eine Vorrichtung und/oder ein Verfahren zum Überwachen eines Fahrers eines Straßenfahrzeugs zu schaffen, welche die oben genannten Nachteile überwinden.The object of the present invention is now to provide an apparatus and / or a method for monitoring a driver of a road vehicle, which overcome the disadvantages mentioned above.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den Merkmalen im Anspruch 1 sowie einer Vorrichtung mit den Merkmalen im Anspruch 5 und hier insbesondere im kennzeichnenden Teil des Anspruchs 1 bzw. des Anspruchs 5 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus den hiervon abhängigen Unteransprüchen.This object is achieved by a method having the features in claim 1 and a device having the features in claim 5 and in particular in the characterizing part of claim 1 and claim 5. Advantageous embodiments and further developments emerge from the subclaims dependent thereon.
Im Kern des erfindungsgemäßen Verfahrens erfolgt ein Überwachen von Öffnungsweiten der Pupillen der Augen des Fahrers.At the heart of the method according to the invention is monitoring of opening widths of the pupils of the eyes of the driver.
Beispielsweise kann über eine Anisokorie, d.h. über einen Unterschied der Pupillenweiten, auf einen Gesundheitszustand einer Person bzw. eines Fahrers eines Kraftfahrzeugs geschlossen werden. So können über die Beobachtung sowie Auswertung dieser Pupillenweiten plötzlich auftretende Erkrankungen, zum Beispiel Hirnblutungen wie homolaterale Subduralblutungen oder Schlaganfälle, automatisch sowie direkt beim Auftreten erkannt werden. Folglich können Gefahren durch eine androhende Bewusstlosigkeit des Fahrers im Straßenverkehr vermieden werden, da eine Änderung des Gesundheitszustandes sofort detektiert wird. Weiterhin kann dadurch eine schnelle Behandlung eingeleitet werden, um weitere Folgeschäden des Fahrers zu vermeiden.For example, via an anisocoria, i. be concluded about a difference in the pupil widths, on a state of health of a person or a driver of a motor vehicle. Thus, by observing and evaluating these pupil widths, suddenly occurring diseases, for example cerebral hemorrhages such as homolateral subdural haemorrhages or strokes, can be detected automatically as well as directly on appearance. Consequently, hazards due to an impending loss of consciousness of the driver in traffic can be avoided since a change in the state of health is detected immediately. Furthermore, a quick treatment can be initiated in order to avoid further consequential damage to the driver.
Durch das vorgeschlagene Verfahren können beispielsweise Unfälle durch unvorhersehbare sowie plötzlich auftretende Erkrankungen des Fahrers eines Straßenfahrzeugs reduziert werden.By the proposed method, for example, accidents can be reduced by unpredictable and sudden illnesses of the driver of a road vehicle.
Beispielsweise können mittels zumindest einer Kamera eine Blickrichtung und/oder Öffnungsweiten der Iris beider Augen zeitgleich bestimmt werden. Dabei werden bevorzugt beide Augen durch die Kamera mittels einer Infrarotlichtquelle beleuchtet, wodurch die Blickrichtung über die Position der Spiegelung der Infrarotlichtquelle sowie die Position der Pupillenmitte ermittelt werden kann. Die Pupillenmitte ist je nach Position der Infrarotlichtquelle entweder schwarz (dark pupil) oder rot leuchtend (bright pupil). Dabei kann die Öffnungsweite der Iris durch die Größe dieser schwarzen bzw. roten Flächen sowie dem Verhältnis zum Außenumfang der Iris bestimmt.For example, by means of at least one camera, a viewing direction and / or opening widths of the iris of both eyes can be determined at the same time. Both eyes are preferably illuminated by the camera by means of an infrared light source, whereby the viewing direction can be determined by the position of the reflection of the infrared light source and the position of the center of the pupil. The center of the pupil is either black (dark pupil) or bright red (bright pupil), depending on the position of the infrared light source. The opening width of the iris can be determined by the size of these black or red areas as well as the ratio to the outer circumference of the iris.
Gemäß einer sehr vorteilhaften Weiterbildung der Idee kann es dabei vorgesehen sein, dass in Abhängigkeit eines Verhältnisses der Öffnungsweiten der Iris beider Augen bei Überschreiten eines Schwellwerts eine Fahrerwarnung und/oder ein Notruf ausgegeben wird, sodass der Fahrer oder auch ein Beifahrer gewarnt wird und eventuell entsprechend reagieren kann. Es ist ebenso denkbar, dass der Notruf direkt an eine Notrufzentrale oder sonstigen zentrale Verwaltungsstelle geleitet wird.According to a very advantageous development of the idea, it may be provided that depending on a ratio of the opening widths of the iris of both eyes when exceeding a threshold, a driver warning and / or an emergency call is issued, so that the driver or a passenger is warned and possibly accordingly can react. It is also conceivable that the emergency call is routed directly to an emergency call center or other central administration office.
Dabei kann es gemäß einer vorteilhaften Ausgestaltung vorgesehen sein, dass eine Umgebungshelligkeit an beiden Augen bestimmt und im Falle einer Abweichung ein Korrekturwert berücksichtigt wird. Bevorzugt erfolgt eine Ermittlung der Umgebungshelligkeit in einem Bereich um das linke bzw. rechte Auge. Dadurch können natürlich verursachte Differenzen zwischen beiden Öffnungsweite der Iris, welche durch eine unterschiedliche Beleuchtung der beiden Augen hervorgerufen werden können, von einer krankhaften Abweichung unterschieden werden. Wenn beispielsweise ein Helligkeitsunterschied festgestellt wird, kann durch den Korrekturwert ein Schwellwert des Öffnungsverhältnisses der Iris des rechten sowie linken Auges verschoben werden, um eine Falschwarnung zu vermeiden. Beispielsweise kann gelten, dass eine zulässige Abweichung der Öffnungsweite der Iris des rechten sowie linken Auges umso größer sein kann, je größer der Beleuchtungsunterschied der beiden Augen ist.In this case, according to an advantageous embodiment, it may be provided that an ambient brightness is determined at both eyes and, in the case of a deviation, a correction value is taken into account. Preferably, a determination of the Ambient brightness in an area around the left or right eye. As a result, naturally caused differences between the two opening width of the iris, which can be caused by a different illumination of the two eyes, be distinguished from a morbid deviation. For example, when a difference in brightness is detected, the correction value may shift a threshold value of the opening ratio of the iris of the right and left eyes to avoid a false warning. For example, it may be the case that the greater the illumination difference of the two eyes, the greater the permissible deviation of the opening width of the iris of the right and left eye can be.
Im Kern der erfindungsgemäßen Vorrichtung erfolgt die Überwachung der Weiten der Pupillen über eine Fahrerkamera. Beispielsweise können die bereits vorhandenen Kameras des Straßenfahrzeugs verwendet werden.At the heart of the device according to the invention is the monitoring of the widths of the pupils via a driver camera. For example, the existing cameras of the road vehicle can be used.
In einer bevorzugten Ausführungsform kann die Kamera der Vorrichtung über eine Infrarotlichtquelle verfügen, sodass die Augen des Fahrers mit dieser Infrarotlichtquelle beleuchtet werden können.In a preferred embodiment, the camera of the device may have an infrared light source so that the driver's eyes can be illuminated with this infrared light source.
Weitere Vorteile der erfindungsgemäßen Vorrichtung sowie des erfindungsgemäßen Verfahrens ergeben sich ferner aus den restlichen abhängigen Unteransprüchen und werden anhand der Ausführungsbeispiele deutlich, welche nachfolgend unter Bezugnahme auf die Figuren näher beschrieben werden.Further advantages of the device according to the invention and of the method according to the invention will become apparent from the remaining dependent subclaims and will be apparent from the embodiments, which are described below with reference to the figures.
