Abstract: Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light guide for routing a light beam to a detector operative to detect interruption of the beam due to an item encroaching upon or overhanging an edge of the platter. In another configuration, the scale includes a perimeter gap between the platter outer edge and scanner housing frame or checkout counter, a light beam directed angularly upward through the gap is partially obstructed by the frame and platter whereby light exits the gap forming a light plane, wherein an object placed on the platter extending across the gap intersects the light plane thus scattering light rays, some of which are sensed by a detector. Various indicators for alerting the operator of off-scale detection are also described.

Abstract: Calibrating extrinsic parameters of an imaging system in an automated data reading system includes obtaining, from the imaging system, image data representing an imaged portion of a planar calibration target. The target is coupled to a housing of the automated data reading system and superimposed on a surface thereof. For example, the calibration target is placed on a conveyer surface, or it is printed on the housing of the automated data reading system. The imaged portion of the planar calibration target includes spaced-apart optical codes disposed at positions that coincide with predetermined locations of the automated data reading system to define known calibration-control points for the surface. Optical codes represented in the image data are decoded to obtain observed calibration-control points used for calibrating the extrinsic parameters based on differences between the known and observed locations of the calibration-control points.

Abstract: Systems and methods are provided for reducing erroneous weighing of items by detecting items extending beyond a peripheral edge of a weigh platter associated with a data reader. For example, in response to a weigh request a scale guard module acquires data indicative of whether an item extends between the weigh platter and another surface, compares the acquired data to reference data, and based on the comparison, determines whether an item extends off the weigh platter and thus on to another surface. The scale guard module may utilize non-electromagnetic compression waves, radio waves, a portion of a data reader's scan field to scan a set of patterns extending along at least one edge of the weigh platter, an imaging based scanner to capture an image of at least one edge of the weigh platter, light beams extending along at least one edge of the weigh platter, or any combination thereof.
