Abstract

A first set of reference images is captured using tracking camera(s). Features are extracted from the first set. A first set of features that pertain to at least non-adjustable part(s) of an enclosed space is selected. Positions of the features of the first set are determined. Latest image(s) is/are captured using the tracking camera(s). Features are extracted from the latest image(s). A second set of features that pertain to at least the non-adjustable part(s) and that match with at least a subset of the first set of features, is selected. Positions of the features of the second set are determined. A difference in a position of a given feature of the second set and a position of a corresponding feature of the first set is determined. The tracking camera(s) is/are calibrated.
