Basler自带SDK修改的类
class MyBaslar
{
private Camera camera = null;
public delegate void ImageEventHandler(object sender, ImageEventArgs e);
public event ImageEventHandler ImageEvent;
private PixelDataConverter converter = new PixelDataConverter();
CogImage8Grey img;
public Camera Camera
{
get { return camera; }
set { camera = value; }
}
public MyBaslar(string cameraSN)
{
camera = new Camera(cameraSN);
camera.CameraOpened += Configuration.AcquireContinuous;
camera.StreamGrabber.ImageGrabbed += OnImageGrabbed;
camera.Open();
}
protected void OnImageEvent(CogImage8Grey image8Grey)
{
ImageEventArgs imageEventargs = new ImageEventArgs(image8Grey);
if (ImageEvent != null)
ImageEvent(this, imageEventargs);
}
public void OneShot()
{
try
{
// Starts the grabbing of one image.
camera.Parameters[PLCamera.AcquisitionMode].SetValue(PLCamera.AcquisitionMode.SingleFrame);
camera.StreamGrabber.Start(1, GrabStrategy.OneByOne, GrabLoop.ProvidedByStreamGrabber);
}
catch (Exception)
{ }
}
public void ContinuousShot()
{
try
{
// Start the grabbing of images until grabbing is stopped.
camera.Parameters[PLCamera.AcquisitionMode].SetValue(PLCamera.AcquisitionMode.Continuous);
camera.StreamGrabber.Start(GrabStrategy.OneByOne, GrabLoop.ProvidedByStreamGrabber);
}
catch (Exception)
{
//
}
}
public void Stop()
{
// Stop the grabbing.
try
{
camera.StreamGrabber.Stop();
}
catch (Exception)
{
//
}
}
public void SetCameraParams(double exposure, double gain)
{
if (camera.Parameters.Contains(PLCamera.Gain))
{
camera.Parameters[PLCamera.Gain].SetValue(gain);
}
else
camera.Parameters[PLCamera.GainAbs].SetValue(gain);
if (camera.Parameters.Contains(PLCamera.ExposureTimeAbs))
camera.Parameters[PLCamera.ExposureTimeAbs].SetValue(exposure);
else
camera.Parameters[PLCamera.ExposureTime].SetValue(exposure);
}
private void OnImageGrabbed(Object sender, ImageGrabbedEventArgs e)
{
if (e.GrabResult.GrabSucceeded)
{
byte[] pixelData = e.GrabResult.PixelData as byte[];
IntPtr pixelPointer = Marshal.UnsafeAddrOfPinnedArrayElement(pixelData, 0);
Bitmap bitmap = new Bitmap(e.GrabResult.Width, e.GrabResult.Height, PixelFormat.Format32bppRgb);
// Lock the bits of the bitmap.
BitmapData bmpData = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, bitmap.PixelFormat);
// Place the pointer to the buffer of the bitmap.
converter.OutputPixelFormat = PixelType.BGRA8packed;
IntPtr ptrBmp = bmpData.Scan0;
converter.Convert(ptrBmp, bmpData.Stride * bitmap.Height, e.GrabResult);
bitmap.UnlockBits(bmpData);
img = new CogImage8Grey(bitmap);//类型转换，将bitmap类型转换成CogImage8Grey类型
OnImageEvent(img);//使用事件将图片传出，方便外部使用
}
GC.Collect();
}
}
public class ImageEventArgs
{
public CogImage8Grey cogImage;
public ImageEventArgs(CogImage8Grey cogImage8)
{
cogImage = cogImage8;
}
}```
外部引用这个类来完成取像显示
namespace BaslerVPGrab
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
MyBaslar cam;
int a = 0;
private void Form1_Load(object sender, EventArgs e)
{
cam = new MyBaslar("23685942");//根据相机S/n来加载相机
cam.ImageEvent += cam_ImageEvent;//注册在类中写的事件
cam.Camera.Parameters[PLCamera.TriggerMode].TrySetValue("Off");//设置触发模式为内触发
cam.Camera.Parameters[PLCamera.TriggerSource].TrySetValue("Line1");
cam.Camera.Parameters[PLCamera.TriggerActivation].TrySetValue("RisingEdge");
Control.CheckForIllegalCrossThreadCalls = false;
}
void cam_ImageEvent(object sender, ImageEventArgs e)
{
cogRecordDisplay1.Image = e.cogImage;
Task t = new Task(() =>
{
a += 1;
label1.Text = a.ToString();
});
t.Start();
}
private void button1_Click(object sender, EventArgs e)
{
cam.ContinuousShot();//连续触发
}
private void button2_Click(object sender, EventArgs e)
{
cam.Stop();//停止采集
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
cam.Camera.Dispose();//相机释放
}
private void button3_Click(object sender, EventArgs e)
{
cam.OneShot();//触发一次
}
}
}```
界面样子
