我是靠谱客的博主甜蜜酸奶，最近开发中收集的这篇文章主要介绍大恒相机+VS开发+Qt 跑通示例工程，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

直接复制和调试大恒相机自带的C++开发软件开发说明书中的示例工程，报错众多，无从下手。
终于经过注释多处代码，跑通了！以此为记，再接再厉。

#include <QDebug>
#include "GalaxyIncludes.h"

// 用户继承掉线事件处理类
class CSampleDeviceOfflineEventHandler : public IDeviceOfflineEventHandler
{
public :
	void DoOnDeviceOfflineEvent(void* pUserParam)
	{
		qDebug() << "收到设备掉线事件！" ;
	}
};

// 用户继承属性更新事件处理类
class CSampleFeatureEventHandler : public IFeatureEventHandler
{
public:
	void DoOnFeatureEvent(const GxIAPICPP::gxstring &strFeatureName, void* pUserParam)
	{
		qDebug() << "收到曝光结束事件";
	}
};


// 用户继承采集事件处理类
class CSampleCaptureEventHandler : public ICaptureEventHandler
{
public:
	void DoOnImageCaptured(CImageDataPointer &objImageDataPointer, void* pUserParam)
	{
		qDebug() << "收到一帧图像";
		qDebug() << "ImageInfo: " << objImageDataPointer->GetStatus();
		qDebug() << "ImageInfo: " << objImageDataPointer->GetWidth();
		qDebug() << "ImageInfo: " << objImageDataPointer->GetHeight();
		qDebug() << "ImageInfo: " << objImageDataPointer->GetPayloadSize();
	}
};

int main(int argc, char *argv[])
{
	// 声明事件回调对象指针
	IDeviceOfflineEventHandler* pDeviceOfflineEventHandler = NULL; // 掉线事件回调对象
	IFeatureEventHandler* pFeatureEventHandler = NULL; // 远端设备事件回调对象
	ICaptureEventHandler* pCaptureEventHandler = NULL; // 采集回调对象

			//		//将最优包长值设置为当前设备的流通道包长值
			//		ObjFeatureControlPtr->GetIntFeature(
			//			"GevSCPSPacketSize")->SetValue(nPacketSize);
			//	}
			//}

			// 设置Buffer处理模式
			//objStreamControlPtr->GetEnumFeature("StreamBufferHandlingMode")->SetValue("OldestFirst");

			// 注册设备掉线事件（目前只有千兆网相机支持此事件通知）
			GX_DEVICE_OFFLINE_CALLBACK_HANDLE hDeviceOffline = NULL;

			ObjFeatureControlPtr->GetFloatFeature("ExposureTime")->SetValue(50);
			//注册远端设备事件:曝光结束事件（目前只有千兆网系列相机支持曝光结束事件）

			// 选择事件源
			//ObjFeatureControlPtr->GetEnumFeature("EventSelector")->SetValue("ExposureEnd");

			// 使能事件
			//ObjFeatureControlPtr->GetEnumFeature("EventNotification")->SetValue("On");
			//GX_FEATURE_CALLBACK_HANDLE hFeatureEvent = NULL;
			//pFeatureEventHandler = new CSampleFeatureEventHandler();
			//hFeatureEvent = ObjFeatureControlPtr->RegisterFeatureCallback("EventExposureEnd", pFeatureEventHandler, NULL);

			// 注册回调采集
			pCaptureEventHandler = new CSampleCaptureEventHandler();
			ObjStreamPtr->RegisterCaptureCallback(pCaptureEventHandler, NULL);

			// 发送开采命令
			ObjStreamPtr->StartGrab();
			ObjFeatureControlPtr->GetCommandFeature("AcquisitionStart")->Execute();
			
			Sleep(100000);
			
			// 发送停采命令
			ObjFeatureControlPtr->GetCommandFeature("AcquisitionStop")->Execute();
			ObjStreamPtr->StopGrab();

			// 注销采集回调
			ObjStreamPtr->UnregisterCaptureCallback();
			// 注销远端设备事件
			//ObjFeatureControlPtr->UnregisterFeatureCallback(hFeatureEvent);
			// 注销设备掉线事件
			ObjDevicePtr->UnregisterDeviceOfflineCallback(hDeviceOffline);
			// 释放资源
			ObjStreamPtr->Close();
			ObjDevicePtr->Close();
