BarCodeScanner Class

Header: #include "easyar/barcode.hpp"
Inherits: RefBase

Description

BarCodeScanner is used for barcode recognition.

Currently only QR code is enabled. You need to call attachCamera to attach a CameraDevice to BarCodeScanner first, then the images from the CameraDevice are used for the recognition. You can call start/stop to enable/disable the scan process. start and stop are very lightweight calls.

You can get a Frame by Augmenter::newFrame which contains current camera image and recognized code string.
