1、首先需要初始化Pylon，即调用PylonInitialize);
2、在一个try{} catch){}语句中进行打开相机的相关操作。
3、调用相机的传输层工厂类定义一个工厂类的引用，并初始化它，也就是CTlFactory& tlFactory = CTlFactory::GetInstance);
4、得到所有连接的pylon相机，DeviceInfoList_t devices; tlFactory.EnumerateDevicesdevices);
5、创建一个相机实例数组，CInstantCameraArray camerasmindevices.size), c_maxCamerasToUse));
6、在一个for循环当中把所有检测到的相机附加到相机实例数组当中，cameras[i].AttachtlFactory.CreateDevicedevice[i]));
7、两个相机开始抓取图像，病定义一个存取抓取结果的变量，cameras.StartGrabbing); CGrabResultPtr ptrGrabResult;
8、for循环控制抓取的图片数量，在循环内定义一个可以标志相机序列的变量，然后通过cameras数组访问相机的相关数据即可
9、最后终止Pylon相机，即调用PylonTerminate
#include <pylon/PylonIncludes.h>
using namespace Pylon;
using namespace std;
static const uint32_t c_countOfImagesToGrab = 10;
static const size_t c_maxCamerasToUse = 2;
int mainint argc, char* argv[])
{
int exitCode = 0;
PylonInitialize);
try {
CTlFactory& tlFactory = CTlFactory::GetInstance);
DeviceInfoList_t devices; if tlFactory.EnumerateDevicesdevices) == 0 )
{
throw RUNTIME_EXCEPTION “No camera present.”);
}
CInstantCameraArray cameras min devices.size), c_maxCamerasToUse));
cout << “devices.size): ” << devices.size) << endl;
for size_t i = 0; i < cameras.GetSize); ++i)
{
cameras[ i ].Attach tlFactory.CreateDevice devices[ i ]));
cout << “Using device ” << cameras[ i ].GetDeviceInfo).GetModelName) << endl;
}
for uint32_t i = 0; i < c_countOfImagesToGrab && cameras.IsGrabbing); ++i)
{
cameras.RetrieveResult 5000, ptrGrabResult, TimeoutHandling_ThrowException);
intptr_t cameraContextValue = ptrGrabResult->GetCameraContext);
cout << “Camera ” << cameraContextValue << “: ” << cameras[ cameraContextValu].GetDeviceInfo).GetModelName) << endl;
cout << “GrabSucceeded: ” << ptrGrabResult->GrabSucceeded) << endl;
cout << “SizeX: ” << ptrGrabResult->GetWidth) << endl;
cout << “SizeY: ” << ptrGrabResult->GetHeight) << endl;
const uint8_t *pImageBuffer = uint8_t *) ptrGrabResult->GetBuffer);
cout << “Gray value of first pixel: ” << uint32_t) pImageBuffer[0] << endl << endl;
}
}
catch const GenericException &e)
{
cerr << “An exception occurred.” << endl << e.GetDescription) << endl;
exitCode = 1;
}
cerr << endl << “Press Enter to exit.” << endl;
while cin.get) != ‘\n’);
PylonTerminate); return exitCode;
}
