Technical Reference

What is DataMatrix?

DataMatrix is a two-dimensional matrix barcode consisting of black and white modules arranged in a square or rectangular pattern. It is widely used in industrial manufacturing, electronics, pharmaceuticals, and logistics for marking small components because it can encode large amounts of data in a very small physical area.

Unlike linear (1D) barcodes, DataMatrix codes include Reed–Solomon error correction, which allows them to be read even when partially damaged or obscured — up to 30 % of a code can be lost while still allowing successful decoding.

About the Detector

This detector was developed by ZBS — Zentrum für Bild- und Signalverarbeitung e. V..

The algorithm supports square DataMatrix symbols as well as selected rectangular sizes (8×18 and 12×26) and can handle mirrored (flipped) codes.

Usage Tips

The detector requires a flat, undistorted view of the code. Images taken at an angle or with perspective distortion will not be detected correctly — ensure the camera is aligned perpendicular to the DataMatrix surface.
Images should have good contrast and even lighting across the code area.
The detector accepts colour images; conversion to grayscale is done automatically.
Multiple codes in one image return multiple hypotheses sorted by confidence.
