详细说明：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,
