Abstract

A method and a computing apparatus (110) for determining adjusted calibration information for a system (100) are disclosed. The computing apparatus (110) obtains (A110) preliminary calibration information for the system (100), wherein the preliminary calibration information indicates a preliminary three-dimensional rotation for the first image sensor (121) and the second image sensor (122) of the system (100), and obtains (A120) a plurality of point pairs, each point pair representing a respective observation of a detected object (130) projected onto a respective two-dimensional image plane of each of the first image sensor (121) and the second image sensor (122). The computing apparatus (110) determines (A130) the adjusted calibration information for the system (100) by solving (A140) an optimization problem whose objective function is dependent on the adjusted calibration information, the objective function being formulated in terms of a reprojection error and a difference measure between triangulated distances and known distances.
