PowerGrid machine vision technology includes a texture-based location algorithm that looks for a pattern of alternating light and dark modules within 2D matrix and direct part mark (DPM) codes. The technology is said to significantly boost read rates where a part’s geometry, poor lighting, occlusion, or print-registration errors make it difficult to capture an image of the entire code. PowerGrid can locate and read codes even when they exhibit significant damage to or complete elimination of the finder pattern, clocking pattern, or quiet zone.
