PlanoMetrix improves scan accuracy by correcting distortions caused by sensor motion mechanics and paper transport irregularities in flatbed and document feeder scanners. Many scanners introduce periodic errors and inconsistencies in horizontal scaling, leading to distortions in scanned documents.
The software works in two phases:
Reference Scan: A graph paper (e.g., millimeter paper) is scanned to determine alignment parameters.
Correction Phase: Subsequent scans are adjusted based on the reference parameters, ensuring consistent scaling and alignment.
This process significantly enhances scan accuracy, making it ideal for precision-sensitive applications such as archival work, document digitization, and CAD-based scanning. PlanoMetrix is open-source and designed for a wide range of scanners.
