使用OpenCV和zbar开源库实现摄像头二维码识别功能

OpenCV+zbar开源库实现摄像头识别二维码，测试验证识别率非常高，已实现简单的应用。 打包源码在VS2013下可以完全编译成功，附加包含OpenCV库及zbar-0.10-setup.exe，zbar-0.10.tar.bz2 下载Demo后需要安装 zbar-0.10-setup.exe 以下代码可以可以完成整个流程的开发，也可以贡献积分下载资源包。 1、 环境准备 （1） OpenCV库2.49 （2） ZBar开源库 （3） VS2013 2、 VS2013环境配置 （1） 配置附加包含目录 C/C++ -- 附加包含目录 include\opencv\include\ include\opencv\include\opencv include\opencv\include\opencv2 include （2） 配置链接器 链接器 -- 附加库目录 lib32\opencv\lib lib32 （3） 配置链接器 链接器--输入--附加依赖项 opencv_core249d.lib opencv_highgui249d.lib opencv_imgproc249d.lib libzbar-0.lib 3、 代码开发 （1）包含头文件 include include include include include include using namespace std; using namespace zbar; using namespace cv; （2）实现函数 void MatToCImage(cv::Mat &mat, CImage &cImage) { //create new CImage int width = mat.cols; int height = mat.rows; int channels = mat.channels(); cImage.Destroy(); //clear cImage.Create(width, height, 8 * channels); //默认图像像素单通道占用1个字节 //copy values uchar* ps; uchar* pimg = (uchar*)cImage.GetBits(); //A pointer to the bitmap buffer int step = cImage.GetPitch(); for (int i = 0; i < height xss=removed>(i)); for (int j = 0; j < width xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed>GetDlgItem(IDC_STATIC_IMG)->GetClientRect(▭); cv::VideoCapture capture(0);//从摄像头读入图像 while (!m_bCloseCamera) { cv::Mat frame; capture >> frame; cv::Mat newframe; cv::Size ResImgSiz = cv::Size(rect.Width(), rect.Height()); cv::resize(frame, newframe, ResImgSiz, CV_INTER_CUBIC); MatToCImage(newframe, imgDst); imgDst.Draw(pThis->GetDlgItem(IDC_STATIC_IMG)->GetDC()->GetSafeHdc(), rect); ImageScanner scanner; scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1); Mat imageGray; cvtColor(frame, imageGray, CV_RGB2GRAY); int width = imageGray.cols; int height = imageGray.rows; uchar *raw = (uchar *)imageGray.data; Image imageZbar(width, height, "Y800", raw, width * height); scanner.scan(imageZbar); //扫描条码 Image::SymbolIterator symbol = imageZbar.symbol_begin(); if (imageZbar.symbol_begin() == imageZbar.symbol_end()) { } else { iIndex++; if (iIndex > 999999) { iIndex = 0; } for (; symbol != imageZbar.symbol_end(); ++symbol) { char szInfo[1024]; memset(szInfo, 0, sizeof(szInfo)); sprintf(szInfo, "[d]类型:%s\r\n条码:%s\r\n", iIndex , symbol->get_type_name().c_str(), symbol->get_data().c_str()); pThis->GetDlgItem(IDC_EDIT1)->SetWindowText(szInfo); } } imageZbar.set_data(NULL, 0); } imgDst.Destroy(); capture.release(); return 0; }
