Abstract

A light section sensor for providing an output of a digital output coordinate has an illuminating device for projecting a light line onto a measured object and an electronic camera for detecting the projected light line on the measured object. A processing device determines at least one measured coordinate in a measured coordinate system on the basis of the light line detected. A coordinate transformation device transforms the measured coordinates from the measured coordinate system into the output coordinates in an output coordinate system by a coordinate transformation. A slope angle determination device determines the slope angle of the light section sensor in relation to a flat surface of the measured object.
