Werden mehrere Messtafeln verwendet, kann das Fahrzeug- Referenzsystem allein aus den Bildern der Messtafeln bestimmt werden. Die Verwendung mehrere Messtafeln ermöglicht es daher insbesondere, ein Fahrzeug- Referenzsystem auch dann zu bestimmen, wenn die Form der Karosserie der Fahrzeugs nicht bekannt ist. If multiple measurement boards are used, the vehicle reference system can be determined solely from the images of the measurement boards. The use of multiple measurement boards therefore makes it possible to determine a vehicle reference system even when the shape of the vehicle body is unknown.
Der Ursprung des Fahrzeug- Referenzsystem kann beispielsweise auf den Mittelpunkt einer virtuellen Linie gelegt werden, welche die beiden Messtafeln, die an den Rädern einer Achse, insbesondere an den Rädern an einer Vorderachse des Fahrzeugs, angebracht sind, miteinander verbindet. Die Längsachse des Fahrzeugs kann als eine Achse bestimmt werden, die orthogonal zu dieser virtuellen Linie ausgerichtet ist und die durch den Ursprung des Fahrzeug- Referenzsystems verläuft. The origin of the vehicle reference system can, for example, be set to the center point of a virtual line connecting the two measuring plates attached to the wheels of an axle, in particular the wheels on a front axle of the vehicle. The longitudinal axis of the vehicle can be defined as an axis oriented orthogonally to this virtual line and passing through the origin of the vehicle reference system.

Figure 2 is a schematic flow diagram of a method for determining the position of an environmental sensor on a vehicle according to an embodiment of the invention.
Das Verfahren umfasst, in einem ersten Schritt S11 die Fahrzeugvermessungsvorrichtung 10 mit den Bildaufnahmevorrichtungen 12a, 12b an einer ersten Position vor dem Fahrzeug zu positionieren, wie es beispielhaft in der Figur 1 A gezeigt ist. Das Verfahren umfasst auch, in einem zweiten Schritt S12 mit den Bildaufnahmevorrichtungen 12a, 12b der Fahrzeugvermessungsvorrichtung 10 ein erstes Bild des Fahrzeugs 2 aufzunehmen und in einem dritten Schritt S13 die Position des Fahrzeugs 2 bzw. der an dem Fahrzeug 2 angebrachten Messtafeln 8 in einem Koordinatensystem der Bildaufnahmevorrichtungen 12a, 12b zu bestimmen. In einem vierten Schritt S14 wird der Umgebungssensor 4 in dem ersten Bild identifiziert und die Position des Umgebungssensors 4 im Koordinatensystem der Bildaufnahmevorrichtungen 12a, 12b bestimmt. The method comprises, in a first step S11, positioning the vehicle measuring device 10 with the image recording devices 12a, 12b at a first position in front of the vehicle, as shown by way of example in Figure 1A.

In a fourth step S14, the environmental sensor 4 is identified in the first image, and the position of the environmental sensor 4 in the coordinate system of the image recording devices 12a, 12b is determined.
Die Fahrzeugvermessungsvorrichtung 10 mit den Bildaufnahmevorrichtungen 12a, 12b wird dann im Schritt S21 an einer zweiten Position, die sich von der ersten Position unterscheidet, vor dem Fahrzeug 2 zu positioniert, wie es beispielhaft in der Figur 1 B gezeigt ist. The vehicle measuring device 10 with the image recording devices 12a, 12b is then positioned in step S21 at a second position, which differs from the first position, in front of the vehicle 2, as shown by way of example in Figure 1B.
Nachdem die Fahrzeugvermessungsvorrichtung 10 an der zweiten Position positioniert worden ist, werden die zuvor in der ersten Position durchgeführten Schritte S12 bis S14 an der zweiten Position der Fahrzeugvermessungsvorrichtung 10 wiederholt: Mit den Bildaufnahmevorrichtungen 12a, 12b wird im Schritt S22 ein zweites Bild des Fahrzeugs 2 aufgenommen und in einem folgenden Schritt S23 wird die Position des Fahrzeugs 2 bzw. der an dem Fahrzeug 2 angebrachten Messtafeln 8 in einem Koordinatensystem der Bildaufnahmevorrichtungen 12a, 12b bestimmt. After the vehicle measuring device 10 has been positioned at the second position, the steps S12 to S14 previously performed in the first position are repeated at the second position of the vehicle measuring device 10: In step S22, a second image of the vehicle 2 is recorded using the image recording devices 12a, 12b, and in a subsequent step S23, the position of the vehicle 2 or of the measuring panels 8 attached to the vehicle 2 is determined in a coordinate system of the image recording devices 12a, 12b.
Mit dieser Information wird im Schritt S25 ein Fahrzeug- Referenzsystem F im Koordinatensystem der Bildaufnahmevorrichtungen 12a, 12b bestimmt, und es wird eine Transformation Tvehicie zwischen diesen beiden Koordinatensystemen bestimmt. With this information, in step S25 a vehicle reference system F is determined in the coordinate system of the image recording devices 12a, 12b, and a transformation T ve hicie between these two coordinate systems is determined.
In einem alternativen Ausführungsbeispiel können das Fahrzeug-Referenzsystem F und eine zugehörige Transformation Tvehicie zwischen den Koordinatensystemen auch auf Grundlage der Position des Fahrzeugs 2 bestimmt werden, die im Schritt S13 bestimmt worden ist, während die Fahrzeugvermessungsvorrichtung 10 an der ersten Position positioniert ist. In an alternative embodiment, the vehicle reference system F and an associated transformation Tvehicie between the coordinate systems may also be determined based on the position of the vehicle 2 determined in step S13 while the vehicle measurement device 10 is positioned at the first position.
Im Schritt S24 wird Umgebungssensor 4 in dem zweiten Bild identifiziert und die Position des Umgebungssensors 4 im Koordinatensystem der Bildaufnahmevorrichtungen 12a, 12b bestimmt. In step S24, environmental sensor 4 is identified in the second image and the position of environmental sensor 4 in the coordinate system of image recording devices 12a, 12b is determined.
In einem erfindungsgemäßen Verfahren können das Fahrzeug 2 und/oder der Umgebungssensor 4 mit bekannten klassischen Verfahren der optischen Mustererkennung und/oder mit Verfahren der künstlichen Intelligenz in den aufgenommen Bildern identifiziert werden. In einem folgenden Schritt S30 wird eine Transformation TCameraicamera2 zwischen den beiden Positionen der Fahrzeugvermessungsvorrichtung 10 bestimmt.

Im Schritt S40 wird diese Transformation TCameraicamera2 zwischen den beiden Positionen der Fahrzeugvermessungsvorrichtung 10 benutzt, um durch Triangulation die 3D-Position Tspot des Umgebungssensors 4 im Referenzsystem der Bildaufnahmevorrichtungen 12a, 12b zu bestimmen. In step S40, this transformation T C ameraicamera2 between the two positions of the vehicle measurement device 10 is used to determine the 3D position T spo t of the environmental sensor 4 in the reference system of the image recording devices 12a, 12b by triangulation.
Mit Hilfe der zuvor im Schritt S25 bestimmten Transformation Tvehicie wird dann im Schritt S50 die im Schritt S40 bestimmte Position Tspot des Umgebungssensors 4 im Referenzsystem der Bildaufnahmevorrichtungen 12a, 12b in die Position des Umgebungssensors 4 im Fahrzeug- Referenzsystem F transformiert. With the aid of the transformation T ve hicie previously determined in step S25, the position T spo t of the environmental sensor 4 in the reference system of the image recording devices 12a, 12b, determined in step S40, is then transformed in step S50 into the position of the environmental sensor 4 in the vehicle reference system F.
Im Schritt S60 wird das Ergebnis, d.h. die auf diese Weise bestimmte Position des Umgebungssensors 4 im Referenzsystem des Fahrzeugs 2, dem Benutzer auf der Anzeigevorrichtung 16 der Fahrzeugvermessungsvorrichtung 10 angezeigt und/oder über die Ausgabevorrichtung 18 ausgegeben. In step S60, the result, i.e. the position of the environmental sensor 4 in the reference system of the vehicle 2 determined in this way, is displayed to the user on the display device 16 of the vehicle measuring device 10 and/or output via the output device 18.
Das Verfahren kann auch umfassen, die zuvor bestimmte Position des Umgebungssensors 4 im Fahrzeug- Referenzsystem F mit einem vorgegebenen Referenzwert Tref zu vergleichen und eine Meldung auszugeben, die anzeigt, ob die in einem erfindungsgemäßen Verfahren bestimmte Position des Umgebungssensors 4 innerhalb eines vorgegebenen Toleranzbereichs um den vorgegebenen Referenzwert Tref liegt, so dass die Position des Umgebungssensors 4 an dem Fahrzeug 2 als korrekt angesehen werden kann, oder ob die bestimmte Position des Umgebungssensors 4 außerhalb des vorgegebenen Toleranzbereichs um den vorgegebenen Referenzwert Tref liegt, so dass die Position des Umgebungssensors 4 an dem Fahrzeug 2 als fehlerhaft angesehen werden muss. The method can also comprise comparing the previously determined position of the environmental sensor 4 in the vehicle reference system F with a predetermined reference value T re f and outputting a message which indicates whether the position of the environmental sensor 4 determined in a method according to the invention lies within a predetermined tolerance range around the predetermined reference value T re f, so that the position of the environmental sensor 4 on the vehicle 2 can be regarded as correct, or whether the determined position of the environmental sensor 4 lies outside the predetermined tolerance range around the predetermined reference value T re f, so that the position of the environmental sensor 4 on the vehicle 2 must be regarded as incorrect.
Mit einem erfindungsgemäßen Verfahren und einer erfindungsgemäßen Fahrzeugvermessungsvorrichtung 10 kann die Position des Umgebungssensors 4 an dem Fahrzeug 2 schnell und zuverlässig bestimmt und überprüft werden. Using a method according to the invention and a vehicle measurement device 10 according to the invention, the position of the environmental sensor 4 on the vehicle 2 can be determined and checked quickly and reliably.
