Data transfer using a camera and a three-dimensional code


Memeti, Jeton; Santos, Flavio; Waldburger, Martin; Stiller, Burkhard (2013). Data transfer using a camera and a three-dimensional code. PIK: Praxis der Informationsverarbeitung und Kommunikation, 36(1):31-37.

Abstract

One- and two-dimensional barcodes have become very popular in past years and are widely used to identify products as well as services. Recently, 2D barcodes, likeQRcodes, are also used to optically transfer a dedicated hyperlink. All 2D barcodes share one major limitation: the storage capacity. To overcome that, time can be introduced as a third dimension. Instead of one, a sequence of barcodes is used to transfer a larger amount of data. The main goal of the present work was to design, implement, and especially evaluate the entire workflow for such a QR codebased, three-dimensional (3D) transmission system on the receiver side, such as a SmartPhone, being able to “read” from a sender, represented by a screen. The steps comprise the capturing of the 3D barcode, the recognition and reading of the sequence of 2D barcodes, and the final retrieval of the original content. Furthermore, adversarial conditions had to be identified, tested, and documented in detail. The prototype achieves a theoretical throughput of 12,288 Byte for 30 seconds transmission intervals, which results in approximately 3,280 bit/s. Future work may focus on increasing the throughput of the system as well as the transmission reliability by applying error detection and correction techniques.
