Claim 19:
20. A non-transitory computer-readable storage medium, storing program instructions executable by one or more processors to perform operations comprising:
obtaining an image from an image sensor, wherein the image comprises a depiction of a physical environment, the depiction including indicium of a direction of a celestial element;
determining an orientation of the image sensor with respect to the direction of the celestial element based on the indicium;
determining an orientation of the image sensor with respect to a global reference direction based on the orientation of the image sensor with respect to the direction of the celestial element and a relationship between the direction of the celestial element and the global reference direction;
obtaining a three-dimensional (3D) model of the physical environment;
determining an orientation of the image sensor with respect to the 3D model; and
determining an orientation of the 3D model with respect to the global reference direction based on the orientation of the image sensor with respect to the 3D model and the orientation of the image sensor with respect to the global reference direction.
