Cognex revs up 2D barcode reading

Texture-based location algorithm.

March 24, 2015   by PLANT Staff

207_cognex_PowerGridPressImage-FINALCognex Corp.’s PowerGrid technology reads 2D matrix and direct part mark (DPM) codes from the inside-out.

Based on a texture-based location algorithm, the technology looks for a pattern of alternating light and dark modules within the code to increase read rates in 2D barcode-reading applications where a part’s geometry, poor lighting, occlusion, or print-registration errors make it difficult to capture an image of the entire code.

Cognex Corp. is a manufacturer of machine vision technology based in Natick, Mass.
