[問題] 兩支CCD攝影機 同時顯示不同畫面

[Timid (吞豚)]

private void pictureBox1_Paint(object sender, PaintEventArgs e)
        {
            Graphics objGraphic = e.Graphics;
            Pen pen = new Pen(Color.Blue);

            objGraphic.DrawLine(pen, (pictureBox1.Width) / 2, 0,
(pictureBox1.Width) / 2, pictureBox1.Height);
            objGraphic.DrawLine(pen, 0, (pictureBox1.Height) / 2,
pictureBox1.Width, (pictureBox1.Height) / 2);
        }

 private void pictureBox2_Paint(object sender, PaintEventArgs e)//20160523新增
        {
            Graphics objGraphic = e.Graphics;
            Pen pen = new Pen(Color.Red);

            objGraphic.DrawLine(pen, (pictureBox2.Width) / 2, 0,
(pictureBox2.Width) / 2, pictureBox2.Height);
            objGraphic.DrawLine(pen, 0, (pictureBox2.Height) / 2,
pictureBox2.Width, (pictureBox2.Height) / 2);
        }

private void UpdateDeviceList()
        {

            //清除設備列表
            DeviceListView.Items.Clear();
            //要求設備enumerator的設備列表
            List<DeviceEnumerator.Device> list =
DeviceEnumerator.EnumerateDevices();
            //每個設備添加在列表中
            foreach (DeviceEnumerator.Device device in list)
            {
                ListViewItem item = new ListViewItem(device.Name);
                item.Tag = device; //連結該設備的數據
                DeviceListView.Items.Add(item);
            }
        }

private void CaptureCamera()//啟動相機的執行續
        {
            _cameraThread =new Thread(new ThreadStart(CaptureCameraCallback));
            _cameraThread.Start();
        }

private void CaptureCameraCallback()
        {

            ListViewItem item = DeviceListView.Items[0];
            //獲取連結設備的數據
            DeviceEnumerator.Device device =(DeviceEnumerator.Device)item.Tag;

            CvCapture cap0 = CvCapture.FromCamera((int)(device.Index));//PO0
            IplImage tpl = Cv.LoadImage("CaptureL.bmp", LoadMode.Color);//讀樣

            Thread.Sleep(1000);

            item = DeviceListView.Items[0];
            //獲取連結設備的數據
            device = (DeviceEnumerator.Device)item.Tag;

            CvCapture cap1 = CvCapture.FromCamera((int)(device.Index));//PO1
            IplImage tpr = Cv.LoadImage("CaptureR.bmp", LoadMode.Color);//讀樣

            Thread.Sleep(1000);

            CvPoint minloc, maxloc;
            double minval, maxval;
            myUI("", minloc_X);//minloc_X寫為空白
            while (true)
            {
             IplImage img0 = cap1.QueryFrame();

IplImage res0 = Cv.CreateImage(Cv.Size(img0.Width-tpr.Width+1,
img0.Height-tpr.Height+1),BitDepth.F32,1);

Cv.MatchTemplate(img0, tpr, res0,MatchTemplateMethod.SqDiffNormed);

Cv.MinMaxLoc(res0, out minval, out maxval, out minloc, out maxloc, null);

Bitmap bm0 = BitmapConverter.ToBitmap(img0);//將img轉成BMP檔
bm0.SetResolution(pictureBox2.Width,pictureBox2.Height);//設定BMP檔的分辨率
pictureBox2.Image = bm0;

             IplImage img1 = cap0.QueryFrame();

IplImage res1 = Cv.CreateImage(Cv.Size(img1.Width - tpl.Width + 1,
img1.Height - tpl.Height + 1), BitDepth.F32, 1);

Cv.MatchTemplate(img1, tpl, res1, MatchTemplateMethod.SqDiffNormed);

Cv.MinMaxLoc(res1, out minval, out maxval, out minloc, out maxloc, null);

Bitmap bm1 = BitmapConverter.ToBitmap(img1);//將img轉成BMP檔
bm1.SetResolution(pictureBox1.Width, pictureBox1.Height);
pictureBox1.Image = bm1;
}
 }

private void video_start_Click(object sender, EventArgs e)
        {
          //CaptureCamera2();
            CaptureCamera();
            flog = 1;
        }

不管怎麼改都是兩個picture box顯示同一支攝影機的畫面

已嘗試過許多方法 也用測試程式試過兩支攝影機都正常

但是使用opencv capture都只截取到同一隻的畫面

不知道是哪裡出了問題 想請教板上高手能否幫忙開釋一下

→ starlion: 第二個device應該從Item[1]取得
→ Timid: 感謝 已修正，不過還是無法
推 KLoVeRs: 需要吳德清主任的幫助嗎?
→ dsin: 你該不會只是把Item[0]改成Item[1]這樣做吧?
