摘要： 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.

摘要： A system and method of detecting an image of a template object in a captured image may include comparing, by a processor, an image model of an imaged template object to multiple locations, rotations, and scales in the captured image. The image model may be defined by multiple model base point sets derived from contours of the imaged template object, where each model base point set inclusive of a plurality of model base points that are positioned at corresponding locations associated with distinctive features of the imaged template object. Each corresponding model base point of the model base point sets may (i) be associated with respective layers and (ii) have an associated gradient vector. A determination may be made as to whether and where the image of the object described by the image model is located in the captured image.

摘要： An automated point of sale system uses one or more cameras to capture images of food products selected by a user for purchase at a food establishment. The point of sale system then compares the images captured to previously captured reference images of such food products being offered at the establishment to find a match for each product, determines the price of each food product the user has selected based on the comparison and match, identifies an account of the user based on a biometric identification of the user and/or reading information from a machine readable token of the user, and automatically causes the account of the user to be charged or debited for the food products identified, thus reducing the check-out time and increasing efficiency of food establishment point of sale systems.

摘要： A calibration process is started by a capacitive input variation when a capacitive button is pressed on a barcode reader. Or, the calibration process is started by the barcode reader scanning a configuration label or special label or barcode after the capacitive button on the barcode reader is inoperative. The calibration process realigns the input and the threshold to correctly configure the capacitive button.

摘要： An optical scanner captures a plurality of images from a plurality of image-capture devices. In response to the activation signal, an evaluation phase is executed, and in response to the evaluation phase, an acquisition phase is executed. In the evaluation phase, a first set of images is captured and processed to produce a virtual frame comprising a plurality of regions, with each region containing a reduced-data image frame that is based on a corresponding one of the plurality of images. Also in the evaluation phase, attributes of each of the plurality regions of the virtual frame are assessed according to first predefined criteria, and operational parameters for the acquisition phase are set based on a result of the assessment. In the acquisition phase, a second set of at least one image is captured via at least one of the plurality of image-capture devices according to the set of operational parameters.

摘要： A data reading system for predicting the removal of a data reader from a charging base unit based on the approach of a user's hand. The data reading system includes a data reader with a power supply, a base unit configured to receive the data reader and to charge the power supply of the data reader responsive to the data reader being coupled to the base unit, a sensor configured to detect the approach of a user's hand, and a processor in operable communication with the sensor and the data reader or the base unit. The processor is configured to apply an appropriate action, such as adjust an amount of current used to charge the power supply of the data reader in the base unit responsive to the sensor detecting the approach of the user's hand.

摘要： Method and device for detecting and classifying a not-known object by a device having a two-dimensional field of view. The method includes a learning step, a detecting step and an inspection step. The learning step includes positioning a first known object in a field of view of the device and then positioning a second known object in the field of view of the device, to obtain images of the first and second known objects. Distinctive characteristics and common characteristics of the objects are identified and used to obtain an equality descriptor relative to common elements of the first and second known objects and a difference descriptor allowing association of the first and second known objects to two distinct classes. The device is then used to detect a third, not-known object. The equality descriptor and the difference descriptor are then used in an inspection step to classify the third not-known object.

摘要： Systems and methods for applying and detecting cross dependent marks incorporated into an electronic or digital image to form a watermark. The electronic or digital image may include encoded information for example a machine-readable symbol. The watermarking may include an encoding and insertion sub-process that inserts one or more marks into an image at a first point in time for form a marked image, an extraction sub-process that extracts the marks at a second point in time, and a detection sub-process 108 that determines if any modifications have been made to the marked image. The marked image may be formed by determining a first original descriptor and first original mark within the image, determining a second original descriptor and second original mark within the image, and incorporating the first original mark into the second original descriptor and incorporating the second original mark into the first original descriptor.
