Description
Die Neuerung betrifft eine Kamerahalterung für Fernseh-Kameras, insbesondere Kameras zur Inspektion von Kanalrohren.The innovation concerns a camera mount for television cameras, especially cameras for inspecting sewer pipes.
Bei der Inspektion von nicht-begehbaren Kanalrohren werden in bekannter Weise ferngesteuerte Kamerafahrwagen eingesetzt, die eine oder mehrere Fernseh-Kameras tragen, um somit den Zustand des Kanalrohres beobachten zu können. Zur komfortablen Beobachtung des Kamerabildes ist es notwendig, dass die Fernseh-Kamera immer ein möglichst aufrechtes Bild liefert. Dies ist aber bei Einsatz des Kamera-Fahrwagens nicht immer sichergestellt.When inspecting sewer pipes that cannot be walked on, remote-controlled camera trolleys are used in the usual way. These carry one or more television cameras in order to be able to observe the condition of the sewer pipe. In order to comfortably observe the camera image, it is necessary that the television camera always delivers an image that is as upright as possible. However, this is not always guaranteed when using the camera trolley.
Aus der Patentschrift DE 39 39 417 Cl ist eine Vorrichtung zur Inspektion von Kanalrohren bekannt, welche eine Kamera aufweist, die mittels eines Antriebs um ihre optische Achse gedreht werden kann, so daß sie immer ein aufrechtes Bild liefert. Dabei erfasst ein Drehwinkelsensor die augenblickliche Lage der Kamera.From the patent specification DE 39 39 417 Cl a device for inspecting sewer pipes is known which has a camera that can be rotated around its optical axis by means of a drive so that it always delivers an upright image. A rotation angle sensor records the current position of the camera.
Aufgabe der vorliegenden Neuerung ist es, eine Kamerahalterung, so wie sie bei Kameravorrichtungen nach dem Stand der Technik eingesetzt wird, derart weiterzubilden, daß auch ohne motorischen Antrieb und Steuerelektronik sichergestellt ist, dass die Kamera ein aufrechtes Bild liefert.The aim of this innovation is to further develop a camera mount, as used in camera devices according to the state of the art, in such a way that even without a motor drive and control electronics, it is ensured that the camera delivers an upright image.
Zur Lösung dieser Aufgabe ist die Neuerung durch die technische Lehre des Anspruchs 1 gekennzeichnet.To solve this problem, the innovation is characterized by the technical teaching of claim 1.
Wesentliches Merkmal der Neuerung ist, daß die Kamera bzw. das Kameragehäuse frei um ihre optische Achse drehbar in einem Kameraträger gelagert ist, wobei das Kameragehäuse an einer Stelle ihres Umfangs mit einem Gewicht beschwert ist,The key feature of the innovation is that the camera or camera housing is mounted in a camera carrier so that it can rotate freely around its optical axis, with the camera housing being weighted down at one point on its circumference.
so daß durch Einwirkung der Schwerkraft sich die Kamera bezüglich ihrer optischen Achse immer lagerichtig ausrichtet und ein aufrechtes Bild liefert.so that, due to the effect of gravity, the camera always aligns itself correctly with respect to its optical axis and delivers an upright image.
Vorteil dieser Anordnung ist, dass zur Lageausrichtung der Kamera weder ein Motor noch eine komplizierte elektronische Steuerung notwendig ist. Dies trägt zur Kostensenkung dieser Vorrichtung bei und erhöht deren Zuverlässigkeit. Weitere Merkmale der Neuerung sind in den Unteransprüchen angegeben.The advantage of this arrangement is that neither a motor nor a complicated electronic control is required to align the camera. This helps to reduce the cost of this device and increases its reliability. Further features of the innovation are specified in the subclaims.
Im folgenden wird die Neuerung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Neuerung hervor.The innovation is explained in more detail below using drawings that merely show one way of carrying out the invention. The drawings and their descriptions reveal further features and advantages of the innovation that are essential to the invention.
Es zeigt:It shows:
Figur 1: eine schematische Seitenansicht im Teilschnitt der neuerungsgemässen Kamerahalterung,Figure 1: a schematic side view in partial section of the new camera mount,
Figur 2: einen Schnitt durch Figur 1 entlang der Schnittlinie H-II.Figure 2: a section through Figure 1 along the line H-II.
In den Zeichnungsfiguren ist der Kameraträger 1 dargestellt, der in etwa glockenförmig das Kameragehäuse 2 umgibt. Im Kameragehäuse 2 ist in bekannter Weise ein Bildaufnehmer mit Objektiv, die Auswerte-Elektronik und ein oder mehrere Lichtquellen angeordnet, um das Blickfeld der Kamera auszuleuchten. The drawings show the camera carrier 1, which surrounds the camera housing 2 in a roughly bell-shaped manner. In the camera housing 2, an image sensor with a lens, the evaluation electronics and one or more light sources are arranged in a known manner in order to illuminate the field of view of the camera.
Am Kameragehäuse 2 sind mindestens zwei Lager 3,4 angeordnet, die andererseits im Kameraträger 1 gelagert sind. Die Lager 3,4 sind vorzugsweise leicht laufende Gleit- oder Kugellager, die es ermöglichen, dass sich das Kameragehäuse 1 im Kameraträger frei um die optische Achse 8 drehen kann.At least two bearings 3, 4 are arranged on the camera housing 2, which are also mounted in the camera carrier 1. The bearings 3, 4 are preferably smooth-running plain or ball bearings, which allow the camera housing 1 to rotate freely around the optical axis 8 in the camera carrier.

Bild- und Steuersignale von der Kamera bzw. zur Kamera werden über ein Kabel 7 übertragen.Image and control signals from or to the camera are transmitted via a cable 7.
Neuerungsgemäss ist nun am Umfang des Kameragehäuses 2 ein Gewicht 6 angeordnet, welches entweder direkt am Kameragehäuse aufgeschraubt werden kann oder über eine Manschette 5 am Gehäuse gehalten wird. Beim Gewicht 6 handelt es sich z.B. um ein Bleigewicht mit ausreichender Masse.According to the innovation, a weight 6 is now arranged on the circumference of the camera housing 2, which can either be screwed directly onto the camera housing or is held on the housing via a sleeve 5. The weight 6 is, for example, a lead weight with sufficient mass.
Verändert nun der Kameraträger 1 während des Inspektionseinsatzes im Kanalrohr, bezogen auf die optische Achse, seine Lage bezüglich des Kameragehäuses 2 in Richtung 10, so richtet sich das Kameragehäuse aufgrund der Schwerkraft, welche auf das Gewicht 6 wirkt, selbständig wieder lagerichtig aus. Da das Kameragehäuse leicht beweglich gelagert ist, erfolgt dieses Ausrichten bereits bei geringer Lageänderung des Kameraträgers 1.If the camera carrier 1 changes its position relative to the camera housing 2 in the direction 10 during the inspection operation in the sewer pipe, based on the optical axis, the camera housing automatically realigns itself due to the force of gravity acting on the weight 6. Since the camera housing is mounted so that it can move slightly, this realignment takes place even with a slight change in the position of the camera carrier 1.
Natürlich ist das Gewicht 6 derart angeordnet, daß sich die Kamera immer so ausrichtet, daß sie ein aufrechtes Bild liefert.Of course, the weight 6 is arranged in such a way that the camera is always aligned so that it delivers an upright image.
Die neuerungsgemasse Kameralagerung ermöglicht es, ohne großen mechanischen und elektronischen Aufwand eine lagerichtige Ausrichtung der Kamera um ihre optische Achse zu gewährleisten.The innovative camera bearing makes it possible to ensure that the camera is correctly aligned around its optical axis without major mechanical and electronic effort.
