大恒相机使用opencv的单帧采集与数据转换

使用大恒sdk黑白相机结合opencv的图像采集
关键是实现大恒的数据到opencv里面的Mat矩阵的数据转换。
下面是关键代码

Mat curr(objImageDataPointer->GetHeight(), objImageDataPointer->GetWidth(), CV_8UC1);
void* pRaw8Buffer = NULL;
pRaw8Buffer = objImageDataPointer->ConvertToRaw8(GX_BIT_0_7);
memcpy(curr.data, pRaw8Buffer, (objImageDataPointer->GetHeight())*(objImageDataPointer->GetWidth()));
flip(curr, curr, 0);

简易的demo

#include<iostream>
#include<tchar.h>

//请用户提前配置好工程头文件目录,需要包含GalaxyIncludes.h
#include"GalaxyIncludes.h"
#include<opencv2\core.hpp>
#include<opencv2\imgproc.hpp>
#include<opencv2\highgui.hpp>
using namespace std;
using namespace cv;

int main() {
	cv::Mat srcimage;
	//在调用其他接口之前必须调用IGXFactory::GetInstance().Init()接口执行初始化。
	IGXFactory::GetInstance().Init();

	//枚举设备
	GxIAPICPP::gxdeviceinfo_vector vectorDeviceInfo;
	IGXFactory::GetInstance().UpdateDeviceList(1000, vectorDeviceInfo);
	for (uint32_t i = 0; i < vectorDeviceInfo.size(); i++){
		cout << vectorDeviceInfo[i].GetVendorName() << endl;
		cout << vectorDeviceInfo[i].GetModelName() << endl;
		//更多设备信息详见IGXDeviceInfo接口
	}

	//打开设备
	if (vectorDeviceInfo.size() > 0) {
		//打开链表中的第一个设备
		CGXDevicePointer objDevicePtr;

		GxIAPICPP::gxstring strSN = vectorDeviceInfo[0].GetSN();
		cout << strSN << endl;

		objDevicePtr = IGXFactory::GetInstance().OpenDeviceBySN(strSN, GX_ACCESS_EXCLUSIVE);//目前只能通过strSN打开

		//设备控制
		CGXFeatureControlPointer objFeatureControlPtr = objDevicePtr->GetRemoteFeatureControl();

		CGXStreamPointer objStreamPtr = objDevicePtr->OpenStream(0);

		//开启流通道采集
		objStreamPtr->StartGrab();

		//给设备发送开采命令
		objFeatureControlPtr = objDevicePtr->GetRemoteFeatureControl();
		objFeatureControlPtr->GetCommandFeature("AcquisitionStart")->Execute();


		//采单帧
		CImageDataPointer objImageDataPtr;
		objImageDataPtr = objStreamPtr->GetImage(500);//超时时间使用500ms，用户可以自行设定

		if (objImageDataPtr->GetStatus() == GX_FRAME_STATUS_SUCCESS)
		{
			//采图成功而且是完整帧，可以进行图像处理...
			cv::Mat srcimage(objImageDataPtr->GetHeight(), objImageDataPtr->GetWidth(), CV_8UC1);
			void* pRaw8Buffer = NULL;
			pRaw8Buffer = objImageDataPtr->ConvertToRaw8(GX_BIT_0_7);
			memcpy(srcimage.data, pRaw8Buffer, (objImageDataPtr->GetHeight())*(objImageDataPtr->GetWidth()));
			cv::flip(srcimage, srcimage, 0);//大恒的图像要进行翻转
			imshow("WINDOW1", srcimage);
			waitKey(0);
		}
		//停采
		objFeatureControlPtr->GetCommandFeature("AcquisitionStop")->Execute();
		objStreamPtr->StopGrab();

		//关闭流通道
		objStreamPtr->Close();


		objDevicePtr->Close();//关闭相机并释放资源
	}
	
	


	IGXFactory::GetInstance().Uninit();
	return 0;
