Abstract: At least some embodiments are directed to systems and methods to optimize relative signal delays in vision systems having illumination assemblies separate from a host. In an example embodiment there is a system that includes a host device having, an imaging assembly coupled to the host device and operable to capture image data, and an illumination assembly coupled to the host device and operable to provide illumination. The system is configured such that the host transmits, to the imaging assembly, a series of exposure signals causing the imaging assembly to capture a series of frames and transmits, to the illumination assembly, a series of illumination signals causing the illumination assembly to provide the illumination as a series of strobes. Thereafter the host evaluate each frame to identify a peak-brightness frame and from that, based on a corresponding illumination signal, determines an appropriate relative signal delay for future operations.

Abstract: Imaging devices, systems, and methods for imaging or scanning objects using composite color light are described herein. An example device includes: a plurality of light sources, each configured to emit light in a different wavelength range; an imaging assembly having an imaging sensor operable to receive light from a field of view (FOV), the imaging sensor configured to capture image data during a frame having an exposure duration and a non-exposure duration; and a microprocessor and computer-readable media storing machine readable instructions that, when executed, cause: a first subset of the plurality of light sources to emit a first light during a first illumination duration that at least partially overlaps with the exposure duration of the frame; and a second subset of the plurality of light sources to emit a second light during a second illumination duration that at least partially overlaps with the non-exposure duration of the frame.

Abstract: Methods and systems for optimizing performance of a machine vision system are disclosed herein. An example method includes obtaining one or more first and second images of a target object, where each of the one or more first and second images include a pass indication and a fail indication, respectively. The example method further includes conducting, by a feasibility setup tool, a feasibility setup analysis by (i) performing machine vision techniques on each of the one or more first and second images and (ii) generating a respective updated result indication for each of the one or more first and second images. The example method further includes comparing the respective updated result indication to the respective pass indications and fail indications for the one or more first and second images, respectively; and based on the comparing, generating one or more suggestions to optimize the performance of the machine vision system.

Abstract: Methods for creating a machine vision job including barcode scanning are disclosed. An example method may be performed by one or more processors and includes detecting a first configuration of a barcode scanning tool including settings of the barcode scanning tool, wherein the first configuration, when executed by a first imaging device operating in a fixed scanning mode, causes the first imaging device to execute the barcode scanning tool in accordance with the settings. The method also includes upgrading the first configuration to a second configuration of the barcode scanning tool, wherein the second configuration, when executed by a second imaging device operating in a machine vision mode, causes the second imaging device to execute the barcode scanning tool in accordance with the settings. The method further includes displaying a user-selectable option to add the barcode scanning tool configured in accordance with the second configuration to the machine vision job.
