ABSTRACT:
The process uses information from the scan sweeps of a laser scanner, and readings with a CCD reader, to obtain a series of stipulated areas corresponding to successive cross-sections of the object as reckoned by moving the object relative to the scanner and the reader. The volume is then obtained by multiplying each of said areas by the feed distance of the object. The possibility is further contemplated of accommodating the slope angles of the scan plane and the read plane, or alternatively neglecting their effects if said angles are sufficiently small. The volume measurement may be accompanied by the reading of an optical code provided on the object.
