Abstract
A 3D object inspection process includes: capturing an object bottom surface 3D profile (a) while an object top surface freely rests on an object seating surface, or (b) without forcibly compressing the top surface of the object against a reference structure distinct from a suction tip; capturing an object top surface 3D profile while (c) the object bottom surface freely rests on the object seating surface, or (d) without forcibly compressing the bottom surface of the object against the reference structure; capturing a plurality of object sidewall images; generating a 3D composite image comprising a 3D digital reconstruction or estimation of the object based upon or using a bottom surface 3D profile image dataset, a top surface 3D profile image dataset, and the sidewall image dataset; and determining a set or array of total object and/or object main body contour values and/or thickness values from the 3D composite image.
