Abstract
A method for compensating range offset of a range sensor 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 located at predetermined reference distances, the method comprising the steps of: a) determining distance values to the reference positions; b) calculating differences between the distance values and the corresponding reference distances; c) determining a range offset value as the maximum of the differences; d) measuring distance values to positions within the spatial environment using the pixel array; e) correcting the measured distance values by subtracting the determined in-situ range offset value from each of the measured distance values.
