  • Publication number: 20190108379
    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to decode a symbol in a digital image. A digital image of a portion of a symbol is received, which includes a grid of pixels and the symbol includes a grid of modules. A spatial mapping is determined between a contiguous subset of modules in the grid of modules to the grid of pixels. Causal relationships are determined, using the spatial mapping, between each module and the grid of pixels. A set of valid combinations of values of neighboring modules in the contiguous subset of modules are tested against the grid of pixels using the causal relationships. A value of at least one module of the two or more neighboring modules is determined based on the tested set of valid combinations. The symbol is decoded based on the determined value of the at least one module.

  • Patent number: 10154177
    Abstract: The present disclosure provides a vision system camera, and associated methods of operation, having a multi-core processor, high-speed, high-resolution imager, FOVE, auto-focus lens and imager-connected pre-processor to pre-process image data provides the acquisition and processing speed, as well as the image resolution that are highly desirable in a wide range of applications. This arrangement effectively scans objects that require a wide field of view, vary in size and move relatively quickly with respect to the system field of view. This vision system provides a physical package with a wide variety of physical interconnections to support various options and control functions. The package effectively dissipates internally generated heat by arranging components to optimize heat transfer to the ambient environment and includes dissipating structure (e.g. fins) to facilitate such transfer.

  • Patent number: 10110829
    Abstract: This invention provides a system and method for auto-regulation of parameters a vision system camera and/or associated illumination of objects imaged by the camera using a plurality of differentiated gain (multi-gain) settings on the camera's image sensor to determine the gain value producing the most-readable image. The image (having the best characteristics) acquired using multiple gain settings can be read for information as a discrete gain image and/or the camera parameters (e.g. global gain and/or global exposure time) can be uniformly set across the pixel array to the best values for acquisition of a subsequent, higher sampled image. This image is then read (e.g. decoded) for information contained within any identified features of interest (e.g. found IDs).

  • Publication number: 20180293418
    Abstract: Systems and methods for reading a two-dimensional matrix symbol or for determining if a two-dimensional matrix symbol is decodable are disclosed. The systems and methods can include a data reading algorithm that receives an image, locates at least a portion of the data modules within the image without using a fixed pattern, fits a model of the module positions from the image, extrapolates the model resulting in predicted module positions, determines module values from the image at the predicted module positions, and extracts a binary matrix from the module values.

  • Patent number: 10068153
    Abstract: A handheld scanner incorporates vision software to allow the handheld scanner to be trained for OCR. The handheld scanner can include a user interface to allow a user to associate an image of a mark with electronic data for the mark. The user interface, along with a range finder, can also be used to influence variables that affect the quality of an image scan, thereby improving the quality of results for the image scan and/or decode process. The handheld scanner can also use a font description file during the decode process. The font description file can be generated using a synthetic image file of a character. The synthetic image file can be created by interpreting a marker font file.

  • Publication number: 20180157882
    Abstract: Computerized methods and systems for locating barcodes applied to objects are provided. A method can receive a first image of a first barcode fragment applied to a first object captured at a first time and identify a first position of the first barcode fragment. The method can also receive a second image of a second barcode fragment captured at a second time and identify a second position of the second barcode fragment. The method can also predict a range of possible positions of the first barcode fragment at the second time based on a tracking model that tracks the first barcode fragment based on the first position, and determine that the first barcode fragment and the second barcode fragment correspond to the same barcode, if the second position is within the range of possible positions of the first barcode fragment at the second time.

  • Publication number: 20180089481
    Abstract: A system and method for communicating at least one of updated configuration information and hardware setup recommendations to a user of an ID decoding vision system is provided. An image of an object containing one or more IDs is acquired with a mobile device. The ID associated with the object is decoded to derive information. Physical dimensions of the ID associated with the object are determined. Based on the information and the dimensions, configuration data can be transmitted to a remote server that automatically determines setup information for the vision system based upon the configuration data. The remote server thereby transmits at least one of (a) updated configuration information to the vision system and (b) hardware setup recommendations to a user of the vision system based upon the configuration data.

  • Patent number: 9904833
    Abstract: A method and apparatus for decoding codes applied to objects for use with an image sensor that includes a two dimensional field of view (FOV), the method including the steps of providing a processor programmed to perform the steps of obtaining an image of the FOV, attempting to decode a code candidate in the image using a first decode algorithm, and where the attempt to decode the code candidate fails, maintaining the image in memory. The method including repeating the above steps until one of a threshold number of attempts to decode the code candidate have failed and the code candidate has been successfully decoded. Further, the method includes accessing the images maintained in memory and attempting to decode the code candidate in at least a subset of the images stored in memory using a second decode algorithm that is different than the first decode algorithm.

Contributions of the first images to the decoding attempt are identified. An updated acquisition-settings order is determined based at least partly upon the contributions of the first images to the decoding attempt. Second images are acquired or processed based at least partly upon the updated acquisition-settings order.

  • Publication number: 20170351892
    Abstract: Systems and methods for use with a handheld mark reader that reduce the time between activation of the reader's trigger and the reader returning a successful decode response. Image processing may be performed prior to the user actuating the trigger and thus obtaining a decodable image with reduced delay. Separate pre-trigger and post-trigger parameters may be used for image decoding. A feedback loop may be incorporated for repeated parameter updates. An adjustable lens may be utilized either with illumination OFF or ON.
