Indicia reading terminals and methods for decoding decodable indicia employing light field imaging

摘要

A terminal for decoding decodable indicia includes a plenoptic imaging subsystem comprising an image sensor array and plenoptic imaging optics operable to project a plenoptic image of a space containing the decodable indicia onto the image sensor array, a hand held housing encapsulating a least a portion of the plenoptic imaging subsystem, a trigger for initiating operation of the plenoptic imaging subsystem to obtain plenoptic image data of the decodable indicia, and an illumination source for projecting illumination onto the decodable indicia; an aimer for projecting an aimer pattern onto the decodable indicia. The terminal is operable, responsive to detecting that the trigger has been actuated by an operator, to obtain plenoptic image data from the image sensor array, to obtain first rendered image data based on at least a portion of the plenoptic image data, and to attempt to decode the decodable indicia represented in the rendered image data.
