Abstract
A method for determining a location of a target includes, at a first location, determining first location coordinates of a measuring device using one or more GNSS signals, determining a first gravitational direction, and capturing a first image using the camera. The method also includes, at a second location, determining second location coordinates of the measuring device, and capturing a second image. The method further includes determining a plurality of correspondence points between the first and second images, determining a first plurality of image coordinates for the plurality of correspondence points in the first image, determining a second plurality of image coordinates for the plurality of correspondence points in the second image, and determining the location of the target using at least the first plurality of image coordinates, the second plurality of image coordinates, and the first gravitational direction.
