Abstract: Methods and systems include using three-dimensional imaging apparatuses to capture three-dimensional images and analyze resulting three-dimensional image data to enhance captured two-dimensional images for scanning related processes such as object identification, symbology detection, object recognition model training, and identifying improper scan attempts or other actions performed by an operator. Imaging systems such as bi-optic readers, handheld scanners, and machine vision systems are described using three-dimensional imaging apparatuses and described capturing three-dimensional images and using with captured two-dimensional images.

Abstract: A weigh platter assembly includes a weigh platter having a proximal edge and a lateral edge and an off-platter detection assembly. The off-platter detection assembly has an assembly field-of-view (field-of-view) extending from the proximal edge and constrained to have an assembly central field-of-view axis substantially parallel to the lateral edge and at least one lateral boundary substantially adjacent to the lateral edge. A light emission assembly has a light source and emits a light away from the proximal edge. A light detection assembly has a light sensor and detects at least a portion of the light reflected towards the proximal edge. A controller allows the measured weight to be recorded in response to a first value from the light detection assembly and prevents the measured weight from being recorded and/or provides an alert in response to a second value from the light detection assembly.

Abstract: Methods and systems for using barcodes to determine item dimensions are disclosed herein. An example method includes a scanner identifying a barcode in an image of an object, and determining a datum associated with the barcode. A physical feature of the object located outside of the barcode is identified. A comparison of the datum associated with the barcode to the physical feature is made; and, in response, at least one dimension of the object is determined.

Abstract: A bioptic barcode reader has a housing having a lower housing portion with an upper surface and an upper housing portion extending above the lower housing portion. A generally horizontal window is positioned at the upper surface and a generally upright window is positioned in the upper housing portion. An illumination assembly has an illumination field-of-view and an imaging assembly, including an image sensor, has an imaging field-of-view with a centerline that is directed at an angle relative to the upper surface. A mirror arrangement is configured to split the imaging field-of-view into first and second portions, redirect the first portion of the imaging field-of-view through the generally upright window, and redirect the second portion of the imaging field-of-view and the illumination field-of-view through the generally horizontal window such that the second portion is covered by the illumination field-of-view at the generally horizontal window.

Abstract: A modular off-platter detection assembly for use with a barcode reader includes a housing, a first light source, a first light sensor, and a controller operatively coupled to the first light source and the first light sensor. The housing is configured to be removably mounted to the barcode reader, a frame supporting the barcode reader, or the workstation. The first light source is positioned within the housing and emits a first light along a first lateral edge of a weigh platter. The first light sensor is positioned within the housing, has a first field-of-view along the first lateral edge, and is configured to detect at least a portion of the first light reflected towards the housing. The controller is configured to provide a first alert in response to receipt of a first value from the first light sensor indicating there is an object extending across the first lateral edge.

Abstract: A convertible slot scanner assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes a chassis body, a circuit board, an imaging sensor, a controller, an image decoder, and a first window. The chassis body includes an upper side, a front side forming an opening, a rear side, and an optical cavity. The circuit board is positioned at or near the upper side of the chassis. The imaging sensor, controller, and image decoder are all operably coupled with the circuit board, with the imaging sensor being directed toward the optical cavity to capture an image frame, the controller being in communication with the imaging sensor, and the image decoder configured to receive the image frame. The first window is configured to at least partially cover the opening of the chassis.

Abstract: Symbology readers and methods of reading DPM codes on objects therewith are provided. The symbology reader include a housing that defines a cavity having a first portion and a second portion. A window that separates the first portion and the second portion of the cavity is positioned within the cavity. The symbology reader includes a diffuser configured to diffusingly reflect light that impinges thereon positioned within the first portion of the cavity. The symbology reader includes an imaging assembly and a first illumination assembly positioned within the second portion of the cavity. The symbology reader includes an optical element configured to direct illumination light to impinge upon the diffuser.

Abstract: A barcode reader having lower and upper housings, a weigh platter in the lower housing, and an off-platter detection assembly. The weigh platter has a proximal edge adjacent the upper housing, a first lateral edge, and a distal edge. The off-platter detection assembly comprises an off-platter indication system having a plurality of linearly aligned light sources, each light source representing a location along the first lateral edge, and controller operatively coupled to the plurality of light sources. The controller is configured to: determine if an object extends over the first lateral edge; determine a location of the object along the first lateral edge; and illuminate a first portion of the light sources representing a distance between the proximal edge of the weigh platter and the object and de-illuminate a second portion of the light sources representing a distance between the object and the distal edge of the weigh platter.

Abstract: A barcode reader having calibration of scanner image brightness with multiple FOVs from a single sensor is disclosed herein. An example barcode reader includes an imaging system having a first and second FOV. A first illumination system is configured to illuminate the first FOV. The first illumination system has a first tolerance range and a first characteristic. A second illumination system is configured to illuminate the second FOV. The second illumination system has a second tolerance range and a second characteristic. The first characteristic is established to achieve a minimum desired brightness at a beginning portion of the first tolerance range and a maximum desired brightness at an end portion of the first tolerance range. The second characteristic is established to achieve a minimum desired brightness at a beginning portion of the second tolerance range and a maximum desired brightness at an end portion of the second tolerance range.
