• 首先需要初始化Pylon，即調(diào)用PylonInitialize();

• 在一個(gè)try{} catch(){}語句中進(jìn)行相關(guān)的操作。

• 調(diào)用相機(jī)的傳輸層工廠類定義一個(gè)工廠類的引用菲茬，并初始化它坚弱，也就是CTlFactory& tlFactory = CTlFactory::GetInstance();

• 得到所有連接的pylon相機(jī)盛正，DeviceInfoList_t devices; tlFactory.EnumerateDevices(devices);

• 創(chuàng)建一個(gè)相機(jī)實(shí)例數(shù)組酒奶，CInstantCameraArray cameras(min(devices.size(), c_maxCamerasToUse));

• 在一個(gè)for循環(huán)當(dāng)中把所有檢測(cè)到的相機(jī)附加到相機(jī)實(shí)例數(shù)組當(dāng)中蚁孔，cameras[i].Attach(tlFactory.CreateDevice(device[i]));

• 兩個(gè)相機(jī)開始抓取圖像，病定義一個(gè)存取抓取結(jié)果的變量讥蟆，cameras.StartGrabbing(); CGrabResultPtr ptrGrabResult;

• for循環(huán)控制抓取的圖片數(shù)量，在循環(huán)內(nèi)定義一個(gè)可以標(biāo)志相機(jī)序列的變量纺阔，然后通過cameras數(shù)組訪問相機(jī)的相關(guān)數(shù)據(jù)即可

• 最后終止Pylon相機(jī)瘸彤，即調(diào)用PylonTerminate。
