Claim One:
1. A method comprising: detecting light from a box object through an imaging lens arrangement with an imaging sensor having two-dimensional photosensitive elements to capture at least one image of the box object, wherein the box object has the shape of a rectangular solid; identifying a geometric mark with fixed dimensions on the box object in the at least one image to find the positions of at least two reference points of the geometric mark in the at least one image, wherein the at least two reference points are separated by a predetermined distance; identifying at least one of a corner of the box object and an edge of the box object; processing a group of parameters and a predetermined mapping to determine one of (a) the volume of the box object and (b) the box dimensions of the box object, with the box dimensions including the width, the length, and the height of the box object; wherein the group of parameters includes (1) the positions of the at least two reference points of the geometric mark in the at least one image, (2) the predetermined distance separating the at least two reference points, and (3) at least one of the position of the corner of the box object identified in the at least one image and the position of the edge of the box object identified in the at least one image; and wherein the predetermined mapping is operative to establish a one-to-one corresponding relationship between a point in an image plane of the imaging sensor and a point in physical space.
