一、二维码识别程序 C/C++ openCV实现

#include <iostream> #include <Magick++.h> #include <zbar.h> #define STR(s) #s using namespace std; using namespace zbar; int main (int argc, char **argv) { if(argc < 2) return(1); #ifdef MAGICK_HOME // http://www.imagemagick.org/Magick++/ // under Windows it is necessary to initialize the ImageMagick // library prior to using the Magick++ library Magick::InitializeMagick(MAGICK_HOME); #endif // create a reader ImageScanner scanner; // configure the reader scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1); // obtain image data Magick::Image magick(argv[1]); // read an image file int width = magick.columns(); // extract dimensions int height = magick.rows(); Magick::Blob blob; // extract the raw data magick.modifyImage(); magick.write(&blob, "GRAY", 8); const void *raw = blob.data(); // wrap image data Image image(width, height, "Y800", raw, width * height); // scan the image for barcodes int n = scanner.scan(image); // extract results for(Image::SymbolIterator symbol = image.symbol_begin(); symbol != image.symbol_end(); ++symbol) { // do something useful with results cout << "decoded " << symbol->get_type_name() << " symbol \"" << symbol->get_data() << '"' << endl; } // clean up image.set_data(NULL, 0); return(0); }
