Determination of information regarding an intensity peak position in a space-time volume () formed by image frames generated by an image sensor () from sensing of light reflected from a measure object () as part of light triangulation. The space-time volume () is further associated with space-time trajectories relating to how feature points of the measure object () map to positions in the space-time volume (). A first hypothetical intensity peak position, HIPP() is obtained (in said space time volume (). A first space time analysis position, STAP() is computed () based on space-time analysis performed locally around the HIPP() and along a first space time trajectory associated with the HIPP(). Said information regarding the intensity peak position is determined () based on the HIPP() and the STAP().
