Tango integration

[dgluhovic]

Do you have any guidance for integrating barcode scanning with Project Tango? We’ve hacked together a custom source to replace CameraSource and process Tango video frames instead, however it doesn’t look workable as the barcode lib seems to require autofocus, which is not available from Tango. Autofocus is not technically required, but we’ve tested your demo app on a variety of devices with no luck at all reading a barcode without autofocus (unlike the Text API). Do you think it’s worth doing some preprocessing, say thresholding, as a way to get around the lack of autofocus?

Sorry, there is no special provision for working with Tango devices.

What kind of codes are you trying to read? 1D barcodes (like EAN/UPC) probably can't be read without autofocus, but QR codes should be readable if scaled up enough. Input images are already binarized before processing, so there shouldn't be any need to preprocess them.

Thanks, indeed these are 1D barcodes. Of the libs we've tried, only Scandit does a decent job of handling these without autofocus, however the interface is too high level/restrictive to support this use case. Any plans to support fixed focus cameras in the future, for 1D codes?
