QR code is widely used in different applications, and its detection is currently being done by software. However, hardware detection using FPGAs offers real-time processing ability, which makes it attractive for time-critical applications, such as high-precision robotics and augmented reality. In light of this, an FPGA algorithm for QR code detection is proposed in this paper. It operates with a maximum latency of 12.2 ms to detect a QR code when the input image resolution is 640×480, which offers a 85.3% performance boost over the best state-ofthe-art software detector according to benchmarks. To the best of the authors’ knowledge, this is the first work that explores the use of FPGA in QR code detection.
