Abstract
Method and device(s) for provision of a pair of real world and image sensor correspondence points for use in calibration of an imaging system () for three dimensional imaging based on light triangulation. Said real world point (--) being provided () as a first virtual intersection between a first real world line () and a second real world line (). Said image sensor point (--) being provided () as a second virtual intersection between a first image line () and a second image line (). A first image () by the imaging system comprises captured light that images the first real world line () and a second image () by the imaging system comprises captured light that images the second real world line (). The first image line () corresponds to positions of intensity peaks of said captured light in the first image () and the second image line () corresponds to positions of intensity peaks of said captured light in the second image ().
