Geometric navigation of optical three=dimensional sensors for 3-D measurement of objects

摘要

The method involves moving the 3-D sensor (1) in space and optically detecting at least three signal markers or three mutually independent values of a signal continuum. The positions of the detected signal markers or values and their identification indices within a defined coordinate sensor system are determined, stored and compared with known positions in a reference coordinate system. A transformation matrix derived from the comparison result using a numerical method transforms the sensor coordinate system into the reference coordinate system. The transformation matrix is used to transform coordinates of an object (8) located in the navigation space in the sensor coordinate system measured using coded strip projections into the reference coordinate system.
