代码如下:
- using HalconDotNet;
- namespace Csharp_CameraSnapShot
- {
- public partial class Form1 : Form
- {
- HObject ho_Image = null;
- HTuple hv_Width = new HTuple(), hv_Height = new HTuple();
- HTuple hv_AcqHandle = null;
- public Form1()
- {
- InitializeComponent();
- }
- //定义一个线程
- Thread HPcamera;
- private void RealTimeSnap_Click(object sender, EventArgs e)
- {
- // 图像实时采集
- HPcamera = new Thread(getCameraImage);
- HPcamera.Start();
- }
- void getCameraImage()
- {
- HOperatorSet.GenEmptyObj(out ho_Image);
- //Image Acquisition 01: Code generated by Image Acquisition 01
- HOperatorSet.OpenFramegrabber("DirectShow", 1, 1, 0, 0, 0, 0, "default", 8, "rgb",
- -1, "false", "default", "[0] HP TrueVision HD", 0, -1, out hv_AcqHandle);
- HOperatorSet.GrabImageStart(hv_AcqHandle, -1);
- while (true)
- {
- ho_Image.Dispose();
- HOperatorSet.GrabImageAsync(out ho_Image, hv_AcqHandle, -1);
- HOperatorSet.GetImageSize(ho_Image, out hv_Width, out hv_Height);
- //Image Acquisition 01: Do something
- HOperatorSet.SetPart(hWindowControl1.HalconWindow, 0, 0, hv_Height - 1, hv_Width - 1);
- HOperatorSet.DispObj(ho_Image, hWindowControl1.HalconWindow);
- }
- }
- private void StopSnap_Click(object sender, EventArgs e)
- {
- if (ho_Image != null)
- {
- ho_Image.Dispose();
- }
- ho_Image = null;
- // 停止
- HPcamera.Abort();

- }
- private void SnapSingleImage_Click(object sender, EventArgs e)
- {
- if (ho_Image == null)
- {
- MessageBox.Show("图像为空,请确认相机是否打开!!!");
- return;
- }
- // 此步表示已经获取到了图像
- HOperatorSet.WriteImage(ho_Image, "bmp", 0, "1.bmp");
- try
- {
- // 可以对图像进行分析
- }
- catch(Exception)
- {
- }
- }
