Abstract
A method of measuring an angle includes orienting a measurement device at a reference position characterized by a reference angle. A first panoramic image defined by a predetermined range of elevation angles is acquired where the first panoramic image includes an object. A first bearing of the object in relation to the reference angle is determined and the measurement device is rotated to a measurement position characterized by a measurement angle. A second panoramic image defined by the predetermined range of elevation angles is acquired where the second panoramic image includes the object. A second bearing of the object in relation to the reference angle is determined. The measurement angle is computed as a function of the first bearing and the second bearing.
