Abstract
Height attributes of features of an object having a plurality of physical features thereon is determined by illuminating the features of the object at a low angle and capturing the reflected light at a camera mounted along the z-axis perpendicular to the object. The reflected light from the features is analyzed to determine if any of the features is of an unacceptable height. The reflected light being either brighter or dimmer than the average determines that the corresponding feature is higher or lower respectively than the average feature.
