Abstract:
A method of determining an azimuth and elevation of a point in an image is provided. The method comprises positioning an imaging device at a first position and acquiring a first image. The method also comprises rotating the imaging device and acquiring a second image at the first position. The first image includes the point, and a portion of the first image overlaps a portion of the second image. The method also includes determining correspondences between features in overlapping portions of the images, determining a first transformation between coordinates of the first image and coordinates of the second image based on the correspondences, and determining a second transformation between the coordinates of the second image and a local coordinate frame. The method also includes computing the azimuth and elevation of the point based on the first transformation and the second transformation.
