Real-time Webcam Barcode Detection with OpenCV and C/C++

The samples demonstrate how to use Dynamsoft Barcode Reader SDK to build a barcode reader application on Windows and Raspberry Pi with a USB webcam.

Getting Started

Windows 10

1. Install OpenCV for Windows.
2. Open the project with Visual Studio 2015.
3. Add the include and lib directories of Dynamsoft Barcode Reader and OpenCV to the project properties.
4. Build the project and copy the relevant *.dll libraries to the output directory

Raspberry Pi Raspbian Jessie

1. Download Dynamsoft Barcode Reader for Raspberry Pi.

2. Extract the package and generate a symbolic link:

   sudo ln -s $(DynamsoftBarcodeReader)/lib/libDynamsoftBarcodeReader.so /usr/lib/libDynamsoftBarcodeReader.so
   

3. Visit license page to get a trial license.

4. Follow the article to install OpenCV.

5. Install Wiring Pi

6. Build the source code:

   g++ -ggdb -I$(DynamsoftBarcodeReader)/include -o barcodereader barcodereader.cpp -lDynamsoftBarcodeReader `pkg-config --libs opencv` -lwiringPi -lpthread
