Cognex: PowerGrid texture-based location algorithm for 2D bar code reading

Read 2D matrix and direct part mark bar codes with new system PowerGrid, a texture-based location algorithm, greatly improves 2D bar code read rates when reading 2D matrix and direct part mark (DPM) codes. Included on the supplier’s DataMan 300X models of fixed-mount bar code readers, the system looks for a pattern of alternating light and dark modules within the code—instead of locating the finder pattern like conventional feature-based algorithms. This makes it ideal for applications where a part's geometry, poor lighting, occlusion or print-registration errors make it difficult to capture an image of the entire code. The system can also locate and read codes in instances with significant damage to (or complete elimination of) the finder pattern, clocking pattern or quiet zone.
