The feature offset data may be offsets between locations of a plurality of features projected by the targeting illumination system within a plurality of calibration image frames captured at different calibration distances. The barcode reader may (i) select two features projected by the targeting illumination system that are present in a barcode image captured via the first lens, (ii) determine a feature offset that indicates an offset between the two features, and (iii) estimate a barcode distance based on the feature offset and the feature offset data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Barcode reader ranging using targeting illumination","description":"A barcode reader comprising a targeting illumination system, a plurality of illumination systems, and a lens assembly may also comprise feature offset data.
