Abstract
A method () of determining a transformation matrix for transformation of ranging data from a first coordinate system for the ranging sensor to a second coordinate system for an image sensor is disclosed. The method comprises providing () a ranging sensor and an image sensor; acquiring () a ranging frame sequence, and an image frame sequence; determining () points of motion in frames of each acquired frame sequence; for each frame in one of the frame sequences: evaluating () if a single motion point has been determined in the frame, and if a single motion point has been determined, evaluating () if a single motion point has been determined in a temporally corresponding frame of the other frame sequence and, in that case, pairing () the temporally corresponding frames, whereby a set of frame pairs is formed, and determining () the transformation matrix based on the set of frame pairs.
