Abstract:
The resolution of an optical measurement system for measuring a surface of an object, wherein a measurement light strip is captured on a surface of an object by means of a matrix sensor with a resolution limited by quantization in a quantization direction, can be improved by calculating an effective mapping location in the quantization direction on the basis of the associated real mapping location and a further real mapping location adjacent to the associated real mapping location in a direction perpendicular to the quantization direction.
