Die vorgenannten Lösungen bzw. Lösungsansätze sind in ihrer Konstruktion teilweise sehr zumindest jedoch aufwändig.The aforementioned solutions or approaches are in their construction sometimes very at least but consuming.
Hier stellt sich die Erfindung die Aufgabe, eine Vorrichtung anzugeben, die in einfacher Art und Weise nicht nur das Lokalisieren sondern auch ein Vermessen eines Objektes in Raum und/oder Ebene ermöglicht.Here the object of the invention is to specify a device in a simple way not just locating but also allows a measurement of an object in space and / or level.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Unteransprüche enthalten bevorzugte Ausführungsformen.Solved The object is achieved by the features of claim 1. subclaims contain preferred embodiments.
Der Erfindung liegt die Idee zugrunde, eine Vorrichtung zu schaffen, die konstruktiv einfach ist und eine einfache Nachrüstung (Montage/Demontage) auch vor Ort ermöglicht. Grundlegend ist vorgesehen, dass zumindest ein rotierender Lichtstrahl von einem katadioptrischen Reflektor in die Ausgangsstellung zurückgestrahlt und über einen weiteren Spiegel auf wenigstens einen Lichtsensor geleitet wird. Dabei wird das Prinzip der Retro-Reflektion an gewandt. Dieses Prinzip basiert darauf, dass spiegelnde und brechende Elemente (= katadioprische Elemente) das Licht umkehren und es in Richtung der Lichtquelle zurücksenden. Die Retro-Reflexion ist die Reflexion, bei der das auftreffende Licht eng gebündelt zur jeweils anleuchtenden Lichtquelle zurückgestrahlt wird. Erreicht werden kann diese Art der Reflexion, mit Hilfe einer großen Anzahl sehr kleiner katadioptrischer Teile (z. B. halb verspiegelter Glaskugeln).Of the Invention is based on the idea to provide a device which is structurally simple and easy to retrofit (Assembly / disassembly) also possible on site. Fundamental is provided that at least one rotating beam of light from a catadioptric reflector returned to the initial position and via a further mirror on at least one light sensor is directed. The principle of retro-reflection is applied. This principle is based on the fact that reflective and refractive elements (= catadioprische elements) turn the light and turn it in the direction of Return the light source. The retro reflection is the reflection, in which the incident light is tightly bundled to each illuminated light source is reflected back. Reached This kind of reflection can be done with the help of a big one Number of very small catadioptric parts (eg semi-mirrored glass spheres).
Retro-reflektierende
Stoffe sind u. a. Reflexfolien, Reflexgewebe oder auch Reflexfarben,
die bei Tageslicht eine normale Aufsichtfarbe zeigen, bei Anfeuchtung
mit künstlichem Licht jedoch den Charakter eines Reflexstoffes
aufweisen. Derartige Folien sind u. a. aus der

Aufbauend auf diese Funktionsweise wird erfindungsgemäß eine Vorrichtung mit einem rotierenden Lichtstrahl als Messeinrichtung in ein vorhandenes System eingebunden, wobei die Lichtstrahlen vom Reflektor in die Ausgangsstellung zurückgestrahlt werden. Befindet sich in diesem Lichtstrahl ein Objekt, erfolgt keine Reflektion und die (der) Lichtsensoren empfangen kein zurückgestrahltes Licht. Die Anzahl bzw. der Bereich der ausfallenden Strahlen ergibt die äußeren Umrisse des Gegenstandes.Building this mode of operation is inventively a Device with a rotating light beam as a measuring device integrated into an existing system, the light beams from Reflector are returned to the starting position. If there is an object in this light beam, no reflection takes place and the light sensor (s) do not receive a reflected light Light. The number or range of the outgoing beams gives the outer outlines of the object.
In einer bevorzugten Ausführung werden wenigstens zwei rotierende Lichtstrahlen so platziert, dass Lage und Ort des Gegenstandes bestimmbar sind. Dabei werden die Lichtquellen so angeordnet, dass sich deren Strahlenbereiche beim Abscannen überschneiden.In a preferred embodiment, at least two rotating Light beams placed so that location and location of the object can be determined. The light sources are arranged so that their radiation areas overlap when scanning.
Der mit dieser Idee verbundene Vorteil liegt in einer genaueren sowie schnelleren Messung des Vorhandenseins eines Objektes als auch dessen örtlicher Lage, wobei auch ein gewünschter mobiler Einsatz dieser Vorrichtung als so genannte Reflexionslichtschranke möglich ist.Of the advantage associated with this idea lies in a more accurate as well faster measurement of the presence of an object as well as its local Location, with a desired mobile use of this Device as a so-called reflection light barrier possible is.
Verwendung findet diese Schranke u. a. überall dort, wo das Erfassen von Objekten auch bezüglich der Lage und Ort mit einfachen Mitteln erwünscht wird. Die Wahl des Winkelmessers in Genauigkeit und Auflösung und damit in Hinblick auf seinen Preis ist abhängig von der gewünschten Qualität der Messung.use finds this barrier u. a. everywhere, where the grasping objects also in terms of location and location with simple Means is desired. The choice of the protractor in accuracy and resolution and thus in terms of its price depending on the desired quality of Measurement.
