Abstract
A method for coordinate generation to be implemented using an orientation device includes the steps of: providing at least three reference marks on a target; aiming the orientation device at a target point on the target, and operating the orientation device such that the orientation device is able to capture an image of the target that contains the reference marks; assigning absolute coordinates to the reference marks in the image captured by the orientation device; and determining relative coordinates of the target point in a coordinate space of the target with reference to the absolute coordinates assigned to the reference marks. An orientation device that performs the method is also disclosed.
