Stationary Dimensioning Apparatus
First Claim
1. A method of employing a dimensioning apparatus to characterize a number of physical dimensions of a load with respect to a reference coordinate system having a number of reference axes when the load is situated in a detected position that is offset from the reference coordinate system by a displacement that comprises at least one of a number of translations along at least some of the number of reference axes and a number of rotations about at least some of the number of reference axes, the method comprising:
- identifying a number of points in space, at least some of which are each representative of a point on a surface of the load as situated in the detected position;
receiving a number of signals that are representative of the displacement;
based at least in part upon the number of signals, transforming at least some of the number of points in space into a number of transformed points in space that are each representative of a point on the surface of the load in a hypothetical position that corresponds with at least a portion of the reference coordinate system; and
determining the number of physical dimensions based at least in part upon at least some of the number of transformed points in space.

Abstract
A stationary dimensioning apparatus dimensions a load on a movable conveyance by detecting a barcode fiducial that is situated on the conveyance and by detecting a large number of points in space that represent points on the surface of the load. The location of the barcode fiducial on the conveyance is compared with a reference location of a reference barcode fiducial, and a translation vector and a rotation vector are calculated to characterize the difference in translation and rotation between the reference barcode fiducial and the barcode fiducial that was detected on the conveyance. The translation and rotation vectors are then employed in a transformation matrix that is used to transform each of the detected points in space into transformed points in space that correspond with a reference coordinate system, such as might be defined in terms of horizontal and vertical directions. Those transformed space in points that are determined to be points on the surface of the conveyance itself can be ignored, and the dimensions of the load can then be calculated from the remaining transformed points in space.
