Claim:
1. A non-parametric method of dimensioning an object of arbitrary shape, the method comprising: capturing, via an image sensor, a three-dimensional (3D) point cloud of data points over a field of view containing the object and a base surface on which the object is positioned; detecting, using a logic circuit, a base plane indicative of the base surface from the point cloud; extracting, using the logic circuit, first ones of the data points corresponding to the object from the point cloud; obtaining, using the logic circuit, a convex hull for the extracted first ones of the data points; generating, using the logic circuit and based on data defining the convex hull, a bounding box of minimum volume to enclose the convex hull, the bounding box having first and second mutually orthogonal planar faces; constraining the first planar face to be generally perpendicular to the base plane; and constraining the second planar face to be generally parallel to the base plane.
