About this app
Swipe the camera view to different directions to get the tab lists.
More hints are available inside a predefined memo group or on the web page.
This QR code reader is optimized for curved, distorted surfaces.
If reflections are low and contrast not too bad, it is possible to read also smaller granulated codes on cylinders like cups.
A combination of a linear perspective transformation and an advanced routing algorithm for curvature and distortion is used in combination with different self-learning black/white converters for detection.
To scan curved codes, it needs a stable preview near and mostly parallel to the top left angle of the square.
With a scanning resolution of 1920 x 1080, QR module numbers of 57 and more are possible, depending on distortion, illumination, and camera quality.
For curved codes the modules size needs to be higher than 5 pixels, so the camera has to be near enough.
