Claim One:
1. A method for determining coordinates of a target in relation to a surveying instrument having a horizontal axis and a vertical axis, the method comprising: determining coordinates of the surveying instrument using one or more GNSS signals, wherein the surveying instrument includes a camera positioned eccentric to a rotation center of the surveying instrument; positioning the camera in a first camera position and orientation; capturing a first image using the camera in the first camera position and orientation; identifying, in the first image, an object point associated with the target; measuring first image coordinates of the object point in the first image; rotating the surveying instrument around the horizontal axis and the vertical axis in order to position the camera in a second camera position and orientation; capturing a second image using the camera in the second camera position and orientation; identifying, in the second image, the object point identified in the first image; measuring second image coordinates of the object point in the second image; and determining the coordinates of the target in relation to the surveying instrument based on the coordinates of the surveying instrument, the first image coordinates, and the second image coordinates.
