A method for compensating range offset of a range sensor (10) located in a predetermined position in a spatial environment and comprising a pixel array adapted for measuring a distance, the spatial environment comprising at least two stationary reference positions (p1, p2) located at predetermined reference distances (rd1, rd2), the method comprising the steps of: a) determining distance values (m1, m2) to the reference positions (p1, p2); b) calculating differences (”1, ”2) between the distance values (m1, m2) and the corresponding reference distances (rd1, rd2); c) determining an in-situ range offset value (rov) as the maximum of the differences (”1, ”2); d) measuring distance values (m) to positions (p) within the spatial environment using the pixel array; e) correcting the measured distance values (m) by subtracting the determined in-situ range offset value (rov) from each of the measured distance values (m). |
