US 12,493,761 B2 · Indicia readers with structure light assemblies

Abstract

Various vision devices are disclosed herein. An example vision device is an indicia reader that includes a housing, an imaging assembly having a field of view (FOV) extending into a product-scanning region and configured to capture image data depicting an environment appearing within the FOV, and an illumination assembly configured to emit a structured light into the product-scanning region such that at least a portion of the structured light overlaps with at least a portion of the FOV in the product-scanning region. The indicia reader is selectively operable pursuant to one of a first or a second set of operating parameters based on a distance value, where that value is determined by analyzing, in the image data, an appearance of the structured light on some portion of an object appearing within the FOV.

Claims20

Dependent claims

An indicia reader having a product-scanning region, comprising:

a housing;
an imaging assembly positioned at least partially within the housing and having at least one field of view (FOV) extending into the product-scanning region, the imaging assembly configured to capture image data depicting an environment appearing within the at least one FOV;
an illumination assembly configured to emit a structured light into the product-scanning region such that at least a portion of the structured light overlaps with at least a portion of the at least one FOV in the product-scanning region;
and
a processor configured to:
process at least some first portion of the image data to determine a distance value based on an appearance of the structured light on at least a first portion of an object in the at least some first portion of the image data;
and
cause the indicia reader to operate pursuant to one of a first set of operating parameters or a second set of operating parameters based on the distance value.

5 more elements

A method of selectively operating an indicia reader, the method comprising:

emitting, via an illumination assembly configured to emit a light into a product-scanning region of the indicia reader such that at least a portion of the light overlaps with at least a portion of at least one field of view (FOV) in the product-scanning region, the light into the product-scanning region wherein the light includes a structured light;
capturing, via an imaging assembly positioned at least partially within a housing of the indicia reader and having the at least one FOV extending into the product-scanning region, image data depicting an environment appearing within the at least one FOV;
processing, via a processor, at least some first portion of the image data to determine a distance value based on an appearance of the structured light on at least a first portion of an object in the at least some first portion of the image data;
and
causing, via the processor, the indicia reader to operate pursuant to one of a first set of operating parameters or a second set of operating parameters based on the distance value.
