Abstract
Techniques for optical resolution determination from barcode chart images are described herein. In an example, a computer system receives an image captured by an image acquisition system having a camera with a lens. The image is of a chart including barcode sets arranged in one or more orientations with respect to an optical axis of the camera, and individual barcodes of a barcode set have a barcode attribute. The computer system decodes the barcode sets in the image using a barcode decoder. The computer system determines, for individual barcode attributes and for individual orientations, a number of decoded barcodes in the barcode sets that match encoded information stored in a barcode manifest. The computer system determines a resolution metric of the image acquisition system for a target barcode decode rate based on a distribution of a decode rate associated with the barcode attribute for the decoded barcodes.
