Considering that all profile points are in one plane (the laser plane), determining the position and rotation angle of this system becomes fairly simple: correlating the measured profile of well-known object with the expected profile. This is where a calibration fixture comes in.

A calibration fixture is an object with a well-known and stable geometry that allows the calculation of rotation and offset for each head.
