Cognex Corporation’s PowerGrid technology that takes an “inside-out” approach to reading 2D matrix and direct part mark (DPM) codes. Instead of conventional feature-based algorithms that start by locating the finder pattern, PowerGrid looks for a pattern of alternating light and dark modules within the code and increases 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. In addition, PowerGrid technology can locate and read codes even when they exhibit significant damage to or complete elimination of the finder pattern, clocking pattern, or quiet zone. Cognex’s PowerGrid technology is now available on the X models of the DataMan 300 series fixed-mount barcode readers.
