Features

Works

• Detect Multiple QR codes present on a frame at the same time.
• Detect and Segment detected QR codes.
• Re-detect and Decord them with openCV function(OpenCV detector is not good, it should be fixed.)

Outputs

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

Environments

• Windows 10
• C/C++, Visual Studio 2019
• openCV 4.1.1
• openMP for Parallel Computing
• Image Resolution 1920x1080

limitation

• QR Code model1, model2 Only
• No distortion removal

Experiments

• Webcam Logitech C920 PRO HD WEBCAM

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)
