Qtechnology cameras have been used for various vision applications to read different types of barcodes, QR-codes and other product labels.
Using the right resolution, lighting and optics, our vision technology is able to recognise the barcode and label text on various products, running up to 50 codes per second. Moreover, it is possible to recognize individual batch numbers, verify the label is correct, detect folds and wrinkles, label position, and much more.

One of the benefits of our label inspection systems, compared to “pure” barcode readers, is that barcodes that cannot be detected by one camera might still be detected by shared information between additional cameras in a system.

All solutions are fully automated and all processing is done within the cameras (no external pc is needed). We also provide the option to create a deep learning dataset, with the deployment of a CNN. All pipelines use Gstreamer, C and Python. The pipelines can be probed through a user interface if manual visual verification is needed.

Apart from developing the label inspection systems, we also have in-house resources to do vision system mechanics and full control of lighting inside the housing.
