New in version 9.0 – The recognition of two-dimensional matrix barcodes with spatial and custom distortions.

Post by Alex » Wed Feb 10, 2016 11:27 am

Beginning from version 9.0 the VintaSoft Barcode .NET SDK supports the recognition of two-dimensional Aztec, QR Code and Han Xin Code barcodes with random surficial distortions. In practice this allows significantly simplify the barcode recognition from photographic camera, web camera or smartphone camera because now is not necessary to align the barcode in front of camera, and is even possible to recognize barcodes from uneven surfaces.

Our developers have spent a lot of fascinating hours developing and improving the algorithm of distortion correction using web and photographic cameras. Below you can watch on such barcodes via “eyes” of our barcode reader:

At some moment our developers started to see the barcodes exactly like that :).


The tests showed that the barcode reader can handle successfully one or more type of distortions specified below:
  • distortion such as "fish-eye"
  • spatial skewing
  • scaling or tension along any axis
  • irregularly (randomly) curved surface
Here are some images with distorted barcodes:

More images with distorted barcodes you can find within the distributive package of VintaSoft Barcode .NET SDK.

If you face any problems in barcode recognition and you feel that our barcode recognition algorithm should solve them, please send your images for test and review at support@vintasoft.com!
