Detect barcodes and QR-codes, and decode their contents.
QR-codes (Quick Response Codes) are popular 2D patterns that contain embedded information, such as a string of text, a URL, etc. They basically work like barcodes, coding information into a high-contrast, geometric pattern that is easier to detect and decode by a machine that more conventional human-written text or drawings.
One can generate QR-codes containing different kinds of information, for example using online QR-code generators, such as http://www.qr-code-generator.com/
JeVois detects and decodes QR-codes and other barcodes. The implementation of the detection and decoding algorithm used in JeVois is from the popular library ZBar, found at http://zbar.sourceforge.net/
You should be able to sustain 30 frames/s with camera resolution 320x240, and 15 frames/s with camera resolution 640x480 when running this module inside the JeVois smart camera.
This module can send standardized serial messages as described in Standardized serial messages formatting. One message is issued for every detected QR-code or barcode, on every video frame.
Note that when
