Abstract:
A method for aiming a surveying instrument towards a selected target is disclosed. The method includes, in at least one embodiment, capturing an image using a camera in the surveying instrument; selecting a target by identifying an object point in the image captured by the surveying instrument; calculating first horizontal and vertical rotation angles based on the object point identified in the image; rotating the surveying instrument over the first horizontal and vertical rotation angles to an intermediate line of sight; measuring a distance to a point along the intermediate line of sight; and calculating second horizontal and vertical rotation angles based on the object point in the image and on the measured distance. In at least one embodiment, the method may be implemented using computer software, hardware, firmware or a combination thereof. There is also disclosed a surveying instrument in which at least one embodiment of the method is implemented.
