Abstract:
A process for measuring the volume of an object, comprising the following steps:placing the object onto a bearing surface;defining a feed direction for the object on the bearing surface;defining a scan plane with a laser beam from a scanner that overlies the bearing surface, the scan plane intersecting the plane of the bearing surface along a scan base line which lies transverse to the feed direction;moving the object across the bearing surface, along the feed direction, relative to the scan plane, until the scan plane will intersect the object;effecting at least one scan of the object;measuring the distance of n points of measurement of a top face on the object;computing the height of the n points of measurement from the bearing surface according to the measured distances;moving the object across the bearing surface, relative to the scan plane, of a predeterminated feed distance along the feed direction;repeating the three last steps until the entire object is scanned;computing the volume according to the height of the n points of measurement from the bearing surface and the predeterminated feed distance along the feed direction.
