1. A position determination system, comprising:
a two-dimensional code arrangement;
a sensor unit; and
an evaluation unit;
wherein:
the sensor unit is configured to capture an image of the two-dimensional code arrangement;
the evaluation unit is configured to process the image of the two-dimensional code arrangement; and
the processing of the image of the two-dimensional code arrangement includes:
identifying a first region of the two-dimensional code arrangement as being a first predefined area dedicated to a first data category and identifying a second region of the two-dimensional code arrangement as being a second predefined area dedicated to a second data category, each of the first and second predefined areas including basic symbols arranged on a surface; and
based on the identification:
decoding the basic symbols arranged in the first predefined area to identify a position of a component with respect to each of six degrees of freedom in a space outside of the two-dimensional code arrangement; and
decoding the basic symbols arranged in the second predefined area to identify data other than a positional orientation of the component in the six degrees of freedom.
