To solve this problem, based on the You Only Look Once version 5 (YOLOv5) algorithm, we propose a lightweight real-time QR code detection algorithm called EBP-YOLOv5. This work introduces an Efficient Channel Attention mechanism in the backbone network to strengthen the network feature ...
采用Verilog硬件描述语言完成了电路设计,在FPGA上对算法进行了验证,整个模块的最高时钟频率可达到267.95 MHz,能够在微秒级的时间内快速检测提取出QR码图像。 A hardware implementation method for rapid detection of QR code based on CORDIC improved algorithm Chen Rongjun1,2,Yu Yongxing1,Zhong Xiumei2,Xie Shun...
The traditional QR code detection algorithm has a high miss detection rate. In this paper, we collected a little sample data of multiple QR codes and annotated them. We used the YOLOv3 and YOLOv5 algorithms to implement the detection of multiple QR codes. Then, we added CBAM to the YOLO ...
For example, Quick Response (QR) code is hard to be identified with severe motion blur caused by camera shaking or object moving. In this paper, a motion blur QR code identification algorithm based on feature extraction and improved adaptive thresholding is proposed. First, this work designs a...
3. Using Hardware Acceleration for QR Code Detection# MaixPy includes a built-in image.QRCodeDetector object that can use hardware acceleration for QR code detection. At a resolution of 320x224, the maximum frame rate for a single-frame algorithm can reach 60+ fps. Note: This feature is su...
Has QR code smoothing process changed? QR code smoothing process changed after 20H2, from pose smoothing to size smoothing. To revert behavior to the previous smoothing process, one would apply a smoothing algorithm if the new QR code pose data is detected within 5 seconds or 10 cm of the ...
