Abstract: Systems, methods, and media are described herein for providing one or more visualizations corresponding to one or more tasks executed by a core processor on image data from one or more imaging devices (e.g., a camera). For example, an inspection cycle of the core processor can be initiated for determining or identifying unexpected events associated with the tasks of the core processor. Each inspection cycle may correspond to a particular imaging device. In some embodiments, an inspection cycle includes inspections of a grabbing task, a pre-processing task, a processing task, an idle period, another type of task, or one or more combinations thereof. A visualization that includes the unexpected event and the inspection cycle is provided for display on a user interface. In some embodiments, the visualization includes a standard error bar for the pre-processing task, processing task, idle period, or one or more combinations thereof.

Abstract: A retail store self-checkout station may be configured to support a number of different sensing features, including (i) status (e.g., empty, not empty, occluded) of a shopping cart or shopping basket, (ii) customer behavior (e.g., potentially shoplifting or committing fraud at the checkout station, and (iii) machine-readable indicia (e.g., barcode) reading error or fraud. If an occlusion of the shopping cart or shopping basket exists, an advanced shopping cart structure and content analyzer may identify that an item is still in the shopping cart or shopping basket via openings defined by a mesh wall thereof.

Abstract: A computer-implemented method of performing a three-dimensional 3D point cloud registration with multiple two-dimensional (2D) images may include estimating a mathematical relationship between 3D roto-translations of dominant planes of objects in a 3D point cloud and bi-dimensional homographies in a 2D image plane, thereby resulting in a 3D point cloud registration using multiple 2D images. A trained classifier may be used to determine correspondence between homography matrices and inferred motion of the dominant plane(s) on a 3D point cloud for paired image frames. A homography matrix between the paired images of the dominant plane(s) on the 2D image plane may be selected based on the correspondence between the inferred motions and measured motion of the dominant plane(s) on the 3D point cloud for the paired image frames. The process may be less computationally intensive than conventional 2D-3D registration approaches.

Abstract: Passive autofocusing is used in image acquisition devices (e.g., machine-readable symbol readers, cameras), and can be employed with shutter and/or event-based image sensors. An aimer pointer is easily detected in images, and one or more characteristics characterized at various focus positions of the optics. A size of a characteristic dimension and/or shape of the aimer pointer and/or a measure of sharpness of the aimer pointer is used to determine which image, and hence focus position, results in an optimized or even optimum (i.e., best) focus. The image acquisition system is then configured accordingly. Measuring aimer pointer size is typically less computationally intensive than conventional approaches. Use of a laser beam to produce the aimer pointer usually requires lower exposure time than other approaches. Image data can advantageously be windowed using a relatively small region of interest (ROI) based on a known aimer pointer position.

Abstract: A computer-implemented system and process of producing a metric quality grade profile for use during inspection of DPM symbol marked on parts may include storing average metrics measured in a controlled environment for a “golden” sample. Measurements of the DPM symbol of the “golden” sample may be performed. Measurements of the metrics of the “golden” sample in an uncontrolled environment may be performed. Average metrics from the uncontrolled environment may be calculated. The averaged metrics from the controlled and uncontrolled environment may be compared. The user may be enabled to set an acceptable grade for the individual metrics. The acceptable grades for the individual metrics as a profile of the DPM symbol in memory.

Abstract: The present disclosure relates to a method for image classes definition and to a method for image multiprocessing and related vision system, which implement said method for image classes definition. The latter comprising an image splitting operation for each image of M input images, the image splitting operation comprising the steps of: a) splitting the image into image portions; b) executing the algorithm onto each image portion with at least one processing unit; c) identifying the image portion associated with a maximum execution time of said algorithm; d) splitting said identified image portion into further image portions; e) checking if a stop criterion is met: e1) if the stop criterion is met, iterating steps a) to e) onto another one of the M input images; e2) if the stop criterion is not met, executing a predefined image processing algorithm onto each of the further image portions; identifying the image portion or further image portion associated with a maximum execution time of said algorithm; and iterating steps d) to e) on the so identified image portions portion or further image portion; wherein after executing steps a) to e) on all of the M input images, the method for image classes definition further comprises the steps of: f) identifying in an image space, for all the M input images, the positions of each split image portion/further image portion and defining clusters (A, B, C) based thereon; g) defining a set of Q image classes (A′, B′, C, AC) based on said clusters (A, B, C), each class (A′, B′, C, AC) being univocally associated with a splitting pattern representing in the image space a plurality of regions to be allocated to a corresponding plurality of processing units of the vision system for image multiprocessing.

Abstract: A code reader may include a light source configured to illuminate a target area in which items are to be located for reading machine-readable indicia associated with the items, an image sensor configured to capture an image of the target area, an illumination drive circuit in electrical communication with the light source, and an image capture circuit. The image capture circuit may be configured to (i) enable and disable the image sensor to capture an image of the target area during the high illumination and a portion(s) of the low illumination of the target area, and (ii) read an image captured by the image sensor. The illumination drive signals may cause the illumination drive circuit to generate a high illumination drive signal to cause the light source to produce a high illumination, and generate a low illumination drive current to cause said light source to produce a low illumination.

Abstract: An optical scanner device includes at least one image capture device and a transmitter of at least one aimer beam. The scanner device determines ranging to a subject using the at least one aimer beam projected to reflect off of a surface of the subject, and detects a position of the aimer-beam reflection within an image frame captured by the image-capture device, the position being a primary indicator of a distance to the subject from the optical scanner device. A secondary indicator of the distance to the subject within the image frame in combination with the first indicator is used to help detect the aimer beam reflection against noise and detect an occurrence of an optical misalignment with possible self-correction of calibration after such misalignment.
