Abstract

A leveling offset meter (LOM) that includes a spirit level having one or more bubbles adapted for movement in two mutually orthogonal planes. An imager configured to image the one or more bubbles and store corresponding image data. A processor/CPU coupled to the imager and responsive to the image data for determining respective angular offsets to the vertical of the bubble in two mutually orthogonal horizontal planes, and means for conveying the angular offsets to a display unit.
