Patent attributes
A barcode reader has a housing, a weigh platter, and an off-platter detection assembly including an imaging assembly in communication with a controller. The imaging assembly has an imager configured to capture an image of first and second lateral edges of the weigh platter and having a field-of-view extending over an upper surface of the weigh platter. The controller is configured to: identify and locate the first and second lateral edges based upon a training image; receive the image from the imager; allow the measured weight to be recorded if determined that a footprint of an object positioned on the weigh platter does not extend over the first and second lateral edges based on the image; and prevent the measured weight from being recorded and/or providing and alert to a user if determined that the footprint of the object does extend over the first and/or second lateral edges.
