Device for orientation and position detection of markings in three-dimensional space

A device Device for orientation and position detection of markings in three-dimensional space, the device comprising:

• at least one marking unit with several markings;
• an optical image capture unit adapted to capture images of the marking unit;
• and
• an evaluation unit adapted to unambiguously determine the orientation and the position of the marking unit,
• wherein the marking unit has at least five markings for determining orientation and position, and
• wherein:
• exactly three markings are arranged on a first straight line and exactly two markings are arranged on a second straight line, wherein the first and second straight lines intersect in one of the markings so that exactly one common marking belongs to both the first and the second straight line,
• the marking unit has at least one communication element for coding the marking unit,
• the image capture unit is adapted to capture an image of the marking unit with the markings and the at least one communication element, wherein the markings and the at least one communication element are each optically active means,
• the evaluation unit is adapted to determine the orientation and position of the marking unit in the captured image from the markings and to determine an identity of the marking unit from the at least one communication element.
• the at least one communication element is arranged on the second straight line between the markings,
• none of the communication elements are taken into account for the determination of orientation and position,
• several marking units are provided, which are operatable simultaneously in the device and which are adapted such that the marking units are distinguishable on the basis of the various communication elements, and
• the evaluation unit is adapted to recognize all markings and/or communication elements in the captured image and to assign 2-dimensional image coordinates to the markings and/or communication elements in the captured image.
