US 12,321,812 B1 · Methods and systems for light based accidental scan avoidance

Abstract

Methods and systems for avoidance of unintended indicia scanning are disclosed herein. An example method may comprise: (1) illuminating, via a first illumination assembly, a predefined region; (2) illuminating, via a second illumination assembly, outside the predefined region, (3) capturing, via an imaging assembly, image data taken over a field of view (FOV), the FOV partially overlapping first illumination light projected from the first illumination assembly and second illumination light from the second illumination assembly; (4) analyzing, via a controller, the image data; (5) causing, when an object is determined to appear within a working range of the at least one FOV and is illuminated with the second illumination light, the indicia reader to operate pursuant to a first set of operating parameters; and (6) causing, when the object is determined to appear within a working range of the at least one FOV and is not illuminated with the second illumination light, the indicia reader to operate pursuant to a second set of operating parameters.

Dependent claims

An indicia reader having a predefined region, the indicia reader comprising:

a housing;
an imaging assembly positioned at least partially within the housing, the imaging assembly having at least one field of view (FOV);
a first illumination assembly configured to provide a first illumination light to the predefined region, the first illumination light overlapping at least partially with the at least one FOV;
a second illumination assembly configured to provide a second illumination light to illuminate outside the predefined region, the second illumination light overlapping at least partially with the at least one FOV;
and
a controller configured to:
analyze image data captured by the imaging assembly;
responsive to determining that an object, appearing within a working range of the at least one FOV, is illuminated with the second illumination light, causing the indicia reader to operate pursuant to a first set of operating parameters;
and
responsive to determining that the object, appearing within the working range of the at least one FOV, is not illuminated with the second light, causing the indicia reader to operate pursuant to a second set of operating parameters.
