我是靠谱客的博主孝顺灯泡，最近开发中收集的这篇文章主要介绍简单使用gige千兆网口basler工业相机，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1，安装basler相机的驱动程序，选择安装pylonc.net

2,创建c#程序，项目添加引用pylonc.net.dll动态库

3，最简单使用gige千兆网口basler工业相机

a，using PylonC.NET;

b, //声明basler相机变量
PYLON_DEVICE_HANDLE hDev = null;
PylonBuffer<Byte> imgBuf = null;
PylonGrabResult_t grabResult;

c, /* This is a special debug setting needed only for GigE cameras.
See 'Building Applications with pylon' in the Programmer's Guide. */

//初始化相机

#if DEBUG
Environment.SetEnvironmentVariable("PYLON_GIGE_HEARTBEAT", "300000" /*ms*/);
#endif
Pylon.Initialize();//初始化相机
Thread.Sleep(1000);
//GigE basler相机
hDev = new PYLON_DEVICE_HANDLE();
#region Bsler相机
uint numDevices; /*有效设备数 */
numDevices = Pylon.EnumerateDevices();
if (0 == numDevices)
{
throw new Exception("No devices found.");//没有相机
}
else
try{

bool isAvail;
//以下只使用一个相机，其index=0，只针对黑白相机 the Mono8 pixel format
hDev = Pylon.CreateDeviceByIndex(0);
Pylon.DeviceOpen(hDev, Pylon.cPylonAccessModeControl
| Pylon.cPylonAccessModeStream);
isAvail = Pylon.DeviceFeatureIsAvailable(hDev, "EnumEntry_PixelFormat_Mono8");
if (!isAvail)
{
/* Feature is not available. */
throw new Exception("Device doesn't support the Mono8 pixel format.");
}
Pylon.DeviceFeatureFromString(hDev, "PixelFormat", "Mono8");
isAvail = Pylon.DeviceFeatureIsAvailable(hDev, "EnumEntry_TriggerSelector_AcquisitionStart");
if (isAvail)
{
Pylon.DeviceFeatureFromString(hDev, "TriggerSelector", "AcquisitionStart");
Pylon.DeviceFeatureFromString(hDev, "TriggerMode", "Off");
}
isAvail = Pylon.DeviceFeatureIsAvailable(hDev, "EnumEntry_TriggerSelector_FrameBurstStart");
if (isAvail)
{
Pylon.DeviceFeatureFromString(hDev, "TriggerSelector", "FrameBurstStart");
Pylon.DeviceFeatureFromString(hDev, "TriggerMode", "Off");
}
isAvail = Pylon.DeviceFeatureIsAvailable(hDev, "EnumEntry_TriggerSelector_FrameStart");
if (isAvail)
{
Pylon.DeviceFeatureFromString(hDev, "TriggerSelector", "FrameStart");
Pylon.DeviceFeatureFromString(hDev, "TriggerMode", "Off");
}
isAvail = Pylon.DeviceFeatureIsWritable(hDev, "GevSCPSPacketSize");

if (isAvail)
{
/* ... The device supports the packet size feature. Set a value. */
Pylon.DeviceSetIntegerFeature(hDev, "GevSCPSPacketSize", 1500);
}
Pylon.DeviceGrabSingleFrame(hDev, 0, ref imgBuf, out grabResult, 500);

//此处只针对80万，200万，500万相机
if (grabResult.SizeX <= 1074 && grabResult.SizeX >= 1024)
{//相机像素略大于80万情况，只取80万
pictureBox1.Size = new Size(512, 384);
}
else if (grabResult.SizeX <= 1650 && grabResult.SizeX >= 1600)
{//相机像素略大于200万情况，只取200万
pictureBox1.Size = new Size(400, 300);
}
else if (grabResult.SizeX <= 2498 && grabResult.SizeX >= 2448)
{//相机像素略大于500万情况，只取500万
pictureBox1.Size = new Size(612, 512);
} //另一种500万相机，未列出，分辨率1944*2592

}
catch (Exception)
{

}

#endregion Bsler相机

d,//开启相机，

timer1.Start();

//取像并显示出来

private void timer1_Tick(object sender, EventArgs e)
{
int ww = Convert.ToInt32(inputW.Text);
int hh = Convert.ToInt32(inputH.Text);

int xx = (grabResult.SizeX - ww) / 2;//多余不取

e，关闭相机

try {
if (hDev.IsValid)//异常，先释放句柄
{
/* ... Close and release the pylon device. */
if (Pylon.DeviceIsOpen(hDev))
{
Pylon.DeviceClose(hDev);
}
Pylon.DestroyDevice(hDev);
}
}
catch (Exception)
{
/*No further handling here.*/
}
Pylon.Terminate();//其次，终结相机
