【算法介绍】

调用Emgu.CV4.8.0自带BarcodeDetector的接口进行调用
【效果展示】


【实现部分代码】

            BarcodeManager bm = new BarcodeManager();
            ImageViewer viewer = new ImageViewer(); //create an image viewer
            VideoCapture capture = new VideoCapture(); //create a camera captue
            Application.Idle += new EventHandler(delegate (object s, EventArgs ee)
            {  //run this until application closed (close button click on image viewer)

                if (mat != null)
                {
                    viewer.Image = mat; //绘制从摄像头采集到的图片到ImageViewer中显示  draw the image obtained from camera
                    CvInvoke.CvtColor(mat,mat,ColorConversion.Bgr2Gray);
                    bm.GetResult(mat);
                   
                }

            });
            viewer.ShowDialog(); //show the image viewer


        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void btn_select_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();

            openFileDialog.RestoreDirectory = true;
            openFileDialog.Multiselect = false;
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {

                src = CvInvoke.Imread(openFileDialog.FileName);
                pictureBox1.Image =src.ToBitmap();


            }

        }

        private void btn_start_Click(object sender, EventArgs e)
        {
            BarcodeManager bm = new BarcodeManager();
            Mat dest = new Mat();
            CvInvoke.CvtColor(src, dest, ColorConversion.Bgr2Gray);
            var results = bm.GetResult(dest);
            pictureBox2.Image =  bm.DrawImage(src.Clone(),results).ToBitmap();
        }
    }
}
