Description

Kamerasystem zur Herstellung von Panoramaaufnahmen  Camera system for producing panoramic images
Die Erfindung betrifft ein Kamerasystem zur Herstellung von Panoramaaufnahmen, mit einem Rahmen, an dem mehrere Kameras fest montiert sind, die in unterschiedliche Richtungen orientiert sind. The invention relates to a camera system for producing panoramic images, comprising a frame on which a plurality of cameras are fixed, which are oriented in different directions.
Es ist bekannt, Panoramaaufnahmen, sowohl im Bereich der Fotografie als auch im Bereich des Films dadurch herzustellen, dass mehrere Kameras an einem gemeinsamen Rahmen befestigt sind und in unterschiedliche Richtungen orientiert sind . Dadurch kann beispielsweise ein streifenförmiger Bereich abgedeckt werden, der sich einen Winkel von 360° rund um das Kamerasystem erstreckt. Es ist aber auch möglich, die Kameras räumlich so anzuordnen, dass der gesamte Raumwinkel rund um das System abgedeckt ist. Eine solche Lösung ist in der CN 20255444 U beschrieben. It is known to produce panoramic images, both in the field of photography and in the field of film in that several cameras are mounted on a common frame and oriented in different directions. As a result, for example, a strip-shaped area can be covered, which extends at an angle of 360 ° around the camera system. But it is also possible to arrange the cameras spatially so that the entire solid angle is covered around the system. Such a solution is described in CN 20255444 U.
Bei der Bearbeitung der Bilder werden die von den Kameras aufgenommenen Einzelbilder zusammengesetzt, um ein durchgängiges Panoramabild zu erhalten. When editing the images, the frames taken by the cameras are combined to obtain a continuous panorama image.
Aus Platzgründen müssen die einzelnen Kameras notwendigerweise außerhalb eines gedachten Mittelpunkts des Rahmens angeordnet sein. Dies bedingt, dass der Bildwinkel der einzelnen Kameras etwas größer sein muss als der Winkelabstand der Kameras, um Lücken im Bild zu vermeiden. Dieser Effekt ist umso stärker, je näher die Aufnahmeobjekte zum Kamerasystem angeordnet sind. Dadurch ergibt sich jedoch ein sogenannter parallaktischer Fehler, der beim Zusammenfügen der Einzelbilder störend ist. For reasons of space, the individual cameras must necessarily be arranged outside an imaginary center of the frame. This requires that the image angle of the individual cameras must be slightly larger than the angular distance of the cameras to avoid gaps in the image. This effect is the stronger, the closer the objects to be photographed are arranged to the camera system. However, this results in a so-called parallactic error, which is disturbing when assembling the individual images.
Aufgabe der vorliegenden Erfindung ist es, diese Nachteile zu vermeiden und ein Kamerasystem anzugeben, das Panoramaaufnahmen mit höchster Qualität auch dann ermöglicht, wenn die Aufnahmeobjekte stark unterschiedliche Entfernungen vom Kamerasystem aufweisen. Object of the present invention is to avoid these disadvantages and to provide a camera system that allows panoramic images with the highest quality even if the recording objects have very different distances from the camera system.
Erfindungsgemäß werden diese Aufgaben dadurch gelöst, dass die Kameras durch eine Raumlinse mit mehreren Abschnitten umgeben sind, die jeweils einer Kamera zugeordnet sind und die im Wesentlichen dicht aneinander grenzen. According to the invention, these objects are achieved in that the cameras are surrounded by a spatial lens with several sections, which are each assigned to a camera and which are substantially adjacent to each other.
Wesentlich an der vorliegenden Erfindung ist, dass innerhalb des Aufnahmebereichs praktisch die gesamte Oberfläche der Raumlinse optisch genutzt wird, so dass die Raumwinkel-Segmente der einzelnen Kameras unter Berücksichtigung der Raumlinse im Mittelpunkt des Kamerasystems zusammenfallen. Dadurch wird erreicht, dass auch dann, wenn in einem Überlappungsbereich zwischen zwei Kameras sowohl relativ nahe Objekte als auch entfernte Objekte vorliegen, ein Zusammenfügen der Bilder mit höchster Qualität möglich ist. It is essential to the present invention that virtually the entire surface of the spatial lens is optically utilized within the recording area, so that the solid angle segments of the individual cameras, taking into account the spatial lens, coincide in the center of the camera system. This ensures that even if in an overlap area between two Cameras both relatively close objects as well as distant objects are present, an assembly of images with the highest quality is possible.
In einer ersten Ausführungsvariante der vorliegenden Erfindung ist vorgesehen, dass die einzelnen Abschnitte der Raumlinse als Konvexlinsen ausgebildet sind. Dadurch kann eine hohe optische Qualität erreicht werden. In a first embodiment of the present invention, it is provided that the individual sections of the spatial lens are designed as convex lenses. As a result, a high optical quality can be achieved.
Gemäß einer zweiten Ausführungsform der vorliegenden Erfindung sind die einzelnen Abschnitte der Raumlinse als Fresnellinsen ausgebildet, die jeweils einer Konvexlinse entsprechen. Dadurch kann die Dicke der Raumlinse und damit auch das Gewicht der gesamten Vorrichtung wesentlich reduziert werden. According to a second embodiment of the present invention, the individual portions of the spatial lens are formed as Fresnel lenses, each corresponding to a convex lens. As a result, the thickness of the spatial lens and thus also the weight of the entire device can be substantially reduced.
Eine besonders begünstigte Ausführungsvariante sieht vor, dass eine erste Gruppe von Kameras in einer Äquatorialebene in regelmäßigen Winkelabständen angeordnet sind und dass eine zweite Gruppe von Kameras jeweils optische Achsen aufweisen, die in einem vorbestimmten Winkel zur Äquatorialebene angeordnet sind . Die erste Gruppe von Kameras kann beispielsweise sechs Kameras umfassen, die jeweils einen horizontalen Bildwinkel von 60° abdecken. Dadurch wird ein streifenförmiger Bildbereich abgedeckt, der sich einer typischen Aufnahmesituation horizontal rund um das Kamerasystem erstreckt. A particularly advantageous embodiment provides that a first group of cameras are arranged in an equatorial plane at regular angular intervals and that a second group of cameras each have optical axes which are arranged at a predetermined angle to the equatorial plane. For example, the first group of cameras may include six cameras, each covering a horizontal viewing angle of 60 °. This covers a strip-shaped image area that extends horizontally around the camera system in a typical recording situation.
Eine zweite Gruppe von Kameras besitzt optische Achsen, die beispielsweise auf einem Kegel mit einem Öffnungswinkel von 70° bis 90° liegen, dessen Achse rechtwinkelig auf die Äquatorialebene angeordnet ist. Dies bedeutet, dass jede optische Achse der zweiten Gruppe von Kameras einen Winkel von 45° bis 55° mit dieser Äquatorialebene einschließt. Die zweite Gruppe von Kameras kann beispielsweise drei Kameras umfassen. Die zweite Gruppe von Kameras deckt somit beispielsweise die Kugelkalotte oberhalb des Aufnahmebereichs der ersten Gruppe von Kameras ab. A second group of cameras has optical axes, for example, on a cone with an opening angle of 70 ° to 90 °, whose axis is perpendicular to the equatorial plane. This means that each optical axis of the second group of cameras includes an angle of 45 ° to 55 ° with this equatorial plane. The second group of cameras may include, for example, three cameras. The second group of cameras thus covers, for example, the spherical cap above the receiving area of the first group of cameras.
Selbstverständlich kann analog zu der zweiten Gruppe von Kameras auch zusätzlich dazu eine dritte Gruppe von Kameras vorgesehen sein, die den Bereich unterhalb des Erfassungsbereichs der ersten Gruppe von Kameras erfasst. Of course, analogously to the second group of cameras, a third group of cameras may additionally be provided which detects the area below the detection area of the first group of cameras.
Bei Verwendung extremer Raumlinsen-Segmente, die in der Lage sind, zumindest eine Halbkugel abzubilden, ist es möglich, mit lediglich zwei Kameras ein vollständiges Panoramabild zu erhalten. When using extreme space lens segments, which are able to image at least one hemisphere, it is possible to obtain a complete panoramic image with only two cameras.
Vorzugsweise kann vorgesehen sein, dass die Fresnellinsen mehrere Ringe aufweisen, deren Bildbereiche einander überlappen. Dadurch ist es möglich, bei der Bildverarbeitung die einzelnen ringförmigen Bildabschnitte so zusammenzufügen, dass keine erkennbaren Bildfehler aufgrund der Ringe auftreten. Dieses so genannte "stitching" kann mit hoher Geschwindigkeit und sehr guter Qualität aus- geführt werden, da die Eigenschaften der Linse bekannt sind und vorab im Algorithmus berücksichtigt werden können. Preferably, it can be provided that the Fresnel lenses have a plurality of rings whose image areas overlap each other. This makes it possible to combine the individual annular image sections in the image processing in such a way that no recognizable image errors due to the rings occur. This stitching can be done with high speed and very good quality. be guided because the properties of the lens are known and can be considered in advance in the algorithm.

Das Kamerasystem der Fig. 1 besteht aus einem Rahmen 1, an dem mehrere Kameras 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i und 2j fest montiert sind . Eine erste Gruppe von insgesamt sechs Kameras 2a, 2b, 2c, 2d, von denen in Fig . 1 zwei nicht sichtbar sind, sind in gleichmäßigen Winkelabständen von 60° in einer Äquatorialebene 3 angeordnet. Eine zweite Gruppe von insgesamt drei Kameras 2e, 2f und 2g sind oberhalb der ersten Gruppe so angeordnet, dass die optischen Achsen auf einem Kegel mit einem Öffnungswinkel von beispielsweise α = 80° liegen. The camera system of Fig. 1 consists of a frame 1 to which a plurality of cameras 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i and 2j are fixedly mounted. A first group of a total of six cameras 2a, 2b, 2c, 2d, of which in Fig. 1 two are not visible, are arranged at equal angular intervals of 60 ° in an equatorial plane 3. A second group of a total of three cameras 2e, 2f and 2g are arranged above the first group so that the optical axes lie on a cone with an opening angle of, for example, α = 80 °.
Drei weitere Kameras 2h, 2i und 2j einer dritten Gruppe sind analog zu denen der zweiten Gruppe schräg nach unten gerichtet. Three further cameras 2h, 2i and 2j of a third group are directed obliquely downwards analogous to those of the second group.
In Fig . 2 ist die Fassung 5 ersichtlich, die mit dem Rahmen 1 fest verbunden ist und insgesamt zwölf etwa trapezförmige bzw. rhombische Fenster bildet, die jeweils einen Abschnitt einer hier nicht dargestellten Raumlinse aufnehmen. In Fig. 2, the version 5 can be seen, which is firmly connected to the frame 1 and a total of twelve forms approximately trapezoidal or rhombic window, each receiving a portion of a space lens, not shown here.
In Fig . 3 ist die Raumlinse 6 in einer Ansicht dargestellt, die der Fig . 2 entspricht. Die einzelnen Abschnitte 7c, 7d, 7e, 7g, 7h und 7j sind analog zu den zugeordneten Kameras 2c, 2d, 2e, 2g, 2h und 2j bezeichnet. In Fig. 3, the spatial lens 6 is shown in a view corresponding to FIG. 2 corresponds. The individual sections 7c, 7d, 7e, 7g, 7h and 7j are designated analogously to the associated cameras 2c, 2d, 2e, 2g, 2h and 2j.
Wie in Fig . 4 ersichtlich, ist jeder der Abschnitte 7d, 7g und 7j als Fresnellinse ausgebildet, die vorzugsweise außen glatt und sphärisch ausgebildet ist. An der Innenseite ist die typische Ringsstruktur ausgebildet. Die Fresnellinsen sind Sammellinsen, entsprechen also jeweils einer Konvexlinse. In der Fig . 5 wird das wesentliche Wirkprinzip der vorliegenden Erfindung erklärt. Beispielhaft sind zwei Kameras 2d und 2g dargestellt, die optische Achsen 12d und 12g aufweisen. Die Kameras 2d und 2g sind jeweils in einem Abstand d von einem Mittelpunkt M angeordnet. Ausgehend von einem gedachten optischen Zentrum l ld und 11g der Kameras 2d und 2g erstreckt sich der Bildbereich innerhalb der Raumlinse 6, der durch den Winkel ß gegeben ist, von einem Abschnitt der Fassung 5 zum andern. Durch die Wirkung der Raumlinse 6 wird der Bildbereich verkleinert, so dass er außerhalb der Raumlinse 6 - abgesehen von einer geringfügigen Überlappung im Bereich der Fassung 5 - jeweils an den Bildbereich der benachbarten Kamera 2d, 2g anschließt. Die Strahlen 10, die den Bildbereich begrenzen, schneiden einander im Mittelpunkt M des Kamerasystems. Der Winkel γ, denen diese Strahlen 10 einschließen, ist aufgrund des Abstands d kleiner als der Winkel ß. As shown in FIG. 4, each of the portions 7d, 7g and 7j is formed as a Fresnel lens, which is preferably smooth and spherical on the outside. On the inside of the typical ring structure is formed. The Fresnel lenses are converging lenses, ie each correspond to a convex lens. In the Fig. Figure 5 explains the main operating principle of the present invention. By way of example, two cameras 2d and 2g are shown, which have optical axes 12d and 12g. The cameras 2d and 2g are each arranged at a distance d from a center M. Starting from an imaginary optical center Id and 11g of the cameras 2d and 2g, the image area within the spatial lens 6, which is given by the angle β, extends from one section of the mount 5 to the other. Due to the effect of the spatial lens 6, the image area is reduced, so that it adjoins the image area of the adjacent camera 2d, 2g apart from the spatial lens 6, apart from a slight overlap in the area of the mount 5. The beams 10 delimiting the image area intersect at the center M of the camera system. The angle γ which these rays 10 include is smaller than the angle β due to the distance d.
Es ist offensichtlich, dass die Fassung 5 so schlank als möglich ausgebildet sein soll, um den verbleibenden parallaktischen Fehler zu minimieren. Gegebenenfalls können einzelnen Abschnitte der Raumlinse einstückig ausgebildet oder geeignet verklebt werden. In diesen Bereichen kann somit der Rahmen entfallen. It is obvious that the socket 5 should be made as slim as possible in order to minimize the remaining parallactic error. Optionally, individual sections of the spatial lens can be integrally formed or adhesively bonded. In these areas, therefore, the frame can be omitted.
