Reliable even under difficult conditions

Robust Reading Of Barcodes & 2D Codes

MVTec software provides robust functions for reading 1D bar codes and 2D codes. Detection remains reliable even under difficult conditions, such as overexposure, print growth, distortions, blur, or very small code sizes.

BAR CODES

1D Codes

MVTec’s bar code reading software reads all common bar codes (also called linear bar codes), regardless of orientation. It decodes reliably even with subpixel element widths or partial occlusions. 

Heavily overexposed codes are detected as well, even when the bars are reduced to only 5% of their original width. It also handles print growth up to 95% and blurred images. This makes it well suited for industrial bar code inspection and print quality control.

Bar codes are read robustly, even under challenging conditions such as overexposure or partial occlusion.

MATRIX CODES

2D Codes

MVTec software supports the following 2D codes: Data Matrix, QR, Micro QR, Aztec, DotCode, and PDF417. Codes are detected reliably even when modules are smaller than 2×2 pixels or finder patterns are distorted.

In addition to printed codes, the software reads Direct Part Mark (DPM) codes that are applied directly to components by laser engraving or dot peening. Such markings are often used in the automotive, medical, and electronics industries.

  • Aztec codes are commonly used in ticketing and labeling applications.
  • Micro QR codes are ideal for identifying small objects when standard QR codes are too large.

ACCORDING TO STANDARDS

Quality Assurance

MVTec software supports comprehensive quality assurance (bar code grading). Bar codes and 2D codes are evaluated according to ISO/IEC 15415, ISO/IEC 15416, AIM DPM-1-2006, and SEMI T10. 

This helps ensure readability and traceability throughout the production process.

MVTec software grades a Data Matrix code according to ISO/IEC 29158.
