本例程大恒水星系列（MER、MER2、ME2P），火星（MARS）均可适用
这四个例程为自己二次分装，非自带例程，而且非常简洁
采集到的图像返回为bitmap格式图像，显示在picturebox中
首先新建一个winform项目，调用Galaxy Viewer中的C#dll
再进行引用
using GxIAPINET;
例程一、连续采集，返回bitmap格式图像
自由采集例程直接调用本例程中的DHcamera文件，改为自己项目的命名空间，可以直接调用
int m_CamNum = 0;
DhCamera m_Cam = new DhCamera(); //声明一个相机类对象数组
private void Open_Click(object sender, EventArgs e)
{
if(m_CamNum>0)
if (!m_Cam.CamOpen())
m_Cam.OpenCameraFunc(0, ShowImage);
}
private void Close_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.CloseCameraFunc();
}
private void Start_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StartAcqFunc();
}
private void Stop_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StopAcqFunc();
}
public void ShowImage(int index, Bitmap objdata)
{
if (!m_Cam.m_bIsColor)
{
//添加调色板
ColorPalette palette;
palette = objdata.Palette;
int i = 0;
for (i = 0; i <= 255; i++)
{
palette.Entries[i] = System.Drawing.Color.FromArgb(i, i, i);
}
objdata.Palette = palette;
}
//BitmapImage objdataImage = BitmapToBitmapImage(objdata);
Action action1 = () =>
{
pictureBox1.Image = objdata;
};
pictureBox1.BeginInvoke(action1);
}
private void Form1_Load(object sender, EventArgs e)
{
DhCamera.initlib();
m_CamNum = DhCamera.GetCamNumFunc(); //获取识别到的相机数量
if (m_CamNum > 0)
textBox1.Text = m_Cam.GetInfo(0); //第一个相机的id
else
textBox1.Text = "未识别到相机";
}
例程二、软触发采集，返回bitmap格式图像
同样直接调用本例程中的DHcamera文件，改为自己项目的命名空间，可以直接调用
int m_CamNum = 0;
DhCamera m_Cam = new DhCamera(); //声明一个相机类对象数组
public Form1()
{
InitializeComponent();
}
private void Open_Click(object sender, EventArgs e)
{
if (m_CamNum > 0)
if (!m_Cam.CamOpen())
m_Cam.OpenCameraFunc(0, ShowImage);
}
private void Close_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.CloseCameraFunc();
}
private void Start_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StartAcqFunc();
}
private void Stop_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StopAcqFunc();
}
public void ShowImage(int index, Bitmap objdata)
{
if (!m_Cam.m_bIsColor)
{
//添加调色板
ColorPalette palette;
palette = objdata.Palette;
int i = 0;
for (i = 0; i <= 255; i++)
{
palette.Entries[i] = System.Drawing.Color.FromArgb(i, i, i);
}
objdata.Palette = palette;
}
//BitmapImage objdataImage = BitmapToBitmapImage(objdata);
Action action1 = () =>
{
pictureBox1.Image = objdata;
};
pictureBox1.BeginInvoke(action1);
}
private void Form1_Load(object sender, EventArgs e)
{
DhCamera.initlib();
m_CamNum = DhCamera.GetCamNumFunc(); //获取识别到的相机数量
if (m_CamNum > 0)
textBox1.Text = m_Cam.GetInfo(0); //第一个相机的id
else
textBox1.Text = "未识别到相机";
}
private void Trigger_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.SoftTriggerCommand();
}
例程三、硬触发采集，返回bitmap格式图像
同样直接调用本例程中的DHcamera文件，改为自己项目的命名空间，可以直接调用
需要注意的是，大恒水星系列相机和火星系列相机可以作为触发的IO有3组，分别是line0、line2、line3
如果想更改触发接口需要更改DHcamera.cs文件中的146行参数，将line0改为line2或者line3。
如果想通过相机输出GPIO信号，参考这个大恒水星火星工业相机GPIO输入输出
//打开触发模式
m_objIGXFeatureControl.GetEnumFeature("TriggerMode").SetValue("On");
//也可以使用Line2，Line3
m_objIGXFeatureControl.GetEnumFeature("TriggerSource").SetValue("Line0");
int m_CamNum = 0;
DhCamera m_Cam = new DhCamera(); //声明一个相机类对象数组
private void Open_Click(object sender, EventArgs e)
{
if(m_CamNum>0)
if (!m_Cam.CamOpen())
m_Cam.OpenCameraFunc(0, ShowImage);
}
private void Close_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.CloseCameraFunc();
}
private void Start_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StartAcqFunc();
}
private void Stop_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StopAcqFunc();
}
public void ShowImage(int index, Bitmap objdata)
{
if (!m_Cam.m_bIsColor)
{
//添加调色板
ColorPalette palette;
palette = objdata.Palette;
int i = 0;
for (i = 0; i <= 255; i++)
{
palette.Entries[i] = System.Drawing.Color.FromArgb(i, i, i);
}
objdata.Palette = palette;
}
//BitmapImage objdataImage = BitmapToBitmapImage(objdata);
Action action1 = () =>
{
pictureBox1.Image = objdata;
};
pictureBox1.BeginInvoke(action1);
}
private void Form1_Load(object sender, EventArgs e)
{
DhCamera.initlib();
m_CamNum = DhCamera.GetCamNumFunc(); //获取识别到的相机数量
if (m_CamNum > 0)
textBox1.Text = m_Cam.GetInfo(0); //第一个相机的id
else
textBox1.Text = "未识别到相机";
}
例程四、作为TCP客户端接收字符串“1”触发采集
字符串可以根据自己需要的协议进行更改
private void SetText(string text)
{
if(text == "1")//根据需要将“1”改为其他接收的字符串
if (m_Cam.CamOpen())
m_Cam.SoftTriggerCommand();
}
IPAddress HostIP;
IPEndPoint point;
Socket socket;
bool flag = true;
string IP = "192.168.1.105";
string IPort = "50123";
int i;
int m_CamNum = 0;
DhCamera m_Cam = new DhCamera(); //声明一个相机类对象数组
private void Open_Click(object sender, EventArgs e)
{
if (m_CamNum > 0)
if (!m_Cam.CamOpen())
m_Cam.OpenCameraFunc(0, ShowImage);
}
private void Close_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.CloseCameraFunc();
}
private void Start_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StartAcqFunc();
}
private void Stop_Click(object sender, EventArgs e)
{
if (m_Cam.CamOpen())
m_Cam.StopAcqFunc();
}
public void ShowImage(int index, Bitmap objdata)
{
if (!m_Cam.m_bIsColor)
{
//添加调色板
ColorPalette palette;
palette = objdata.Palette;
int i = 0;
for (i = 0; i <= 255; i++)
{
palette.Entries[i] = System.Drawing.Color.FromArgb(i, i, i);
}
objdata.Palette = palette;
}
//BitmapImage objdataImage = BitmapToBitmapImage(objdata);
Action action1 = () =>
{
pictureBox1.Image = objdata;
};
pictureBox1.BeginInvoke(action1);
}
private void Form1_Load(object sender, EventArgs e)
{
DhCamera.initlib();
m_CamNum = DhCamera.GetCamNumFunc(); //获取识别到的相机数量
if (m_CamNum > 0)
textBox1.Text = m_Cam.GetInfo(0); //第一个相机的id
else
textBox1.Text = "未识别到相机";
}
private void Trigger_Click(object sender, EventArgs e)
{
try
{
HostIP = IPAddress.Parse(IP); //获取Ip
point = new IPEndPoint(HostIP, Int32.Parse(IPort)); //将网络端点表示为IP地址和端口号
socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); //使用Socket的构造函数实例化一个Socket对象，以遍连接远程主机
socket.Connect(point); //调用Connect方法连接远程主机
Thread thread = new Thread(new ThreadStart(Proccess));
thread.Start();
}
catch
{
}
}
private void SetText(string text)
{
if(text == "1")
if (m_Cam.CamOpen())
m_Cam.SoftTriggerCommand();
}
private void Proccess()
{
if (socket.Connected)
{
while (flag)
{
byte[] receiveByte = new byte[64];
int r = socket.Receive(receiveByte, receiveByte.Length, 0);
string strInfo = Encoding.UTF8.GetString(receiveByte,0,r);
this.Invoke(new SetTextCallback(SetText), new object[] { strInfo });
}
}
}
delegate void SetTextCallback(string text);
