Abstract
A method for determining a height of a feature of an object is provided. The method includes generating, using a computing device, on an image of a scan volume that includes the object, a marker that crosses an edge of the feature, calculating, using the computing device, for each of a plurality of laminographic images, a profile along the generated marker, each laminographic image having an associated height, computing, using the computing device, an edge slope associated with the feature for each of the plurality of profiles, identifying, using the computing device, a focused laminographic image as the laminographic image of the plurality of laminographic images having the steepest edge slope, and determining the height of the object as the height associated with the focused laminographic image.
