Claim 0:
1. A method comprising:
determining a first relative rotation of an imaging sensor between a first orientation of the imaging sensor and a second orientation of the imaging sensor;
determining a second relative rotation of the imaging sensor between a third orientation of the imaging sensor and a fourth orientation of the imaging sensor;
determining a relative orientation of the imaging sensor with respect to a reference frame based on the first relative rotation and the second relative rotation;
wherein determining the first relative rotation comprises:
obtaining a first image of a first point in a three-dimensional space and a second image of a second point in the three-dimensional space, using the imaging sensor at the first orientation;
obtaining a third image of the first point and a fourth image of the second point, using the imaging sensor at the second orientation;
determining the first relative rotation based on the first image, the second image, the third image and the fourth image.
