Multiple QR codes Detection, Segmentation, and Decoding

• A real-time multiple QR codes decorder based on C++, openCV, and openMP

• Youtube #1 https://youtu.be/atH0RJN-ODs
• Youtube #2 https://youtu.be/QyaFEmmOGdk

Features

Works

• Detect all QR codes presented on a frame at the same time
• Segment the detected QR codes
• Decord them with openCV function (But, OpenCV Decoder shows poor performance...)

Outputs

• The images of segmented QR codes (mode1: not-aligned, mode2: aligned)
• The positions
• The decorded informations

limitation

• QR Code model1, model2 only

Environments

• Windows 10
• C/C++, Visual Studio 2019
• openCV 4.1.1
• openMP for Parallel Computing
• Tested on image resolution 1920x1080

How to Run

1. Download OpenCV 4.1.1(https://sourceforge.net/projects/opencvlibrary/files/4.1.1/opencv-4.1.1-vc14_vc15.exe/download)
2. Decompress it on the path "C:"
3. Clone this project
4. Open the project file and complie it
5. Run it with release mode (Debug mode is slow)
