opencv笔记8----从大恒工业摄像头读取图像2013-10-2510:313280人阅读评论(9)收藏举报采用大恒MER系列工业摄像机，不能用OpenCV自带函数打开摄像头，需要用厂商提供的API工业摄像头采集的图片格式为BYTE，opencv需要从内存中读取BYTE，转化成IplImage*(inC)或者Mat(inc++)[cpp]viewplaincopyprint?#includestdafx.h#includecamera.h#includeiostream#includeopencv2/opencv.hppusingnamespacecv;GX_DEV_HANDLEhDevice=NULL;staticintkeycode;MERCamera::MERCamera(){GX_STATUSstatus=GX_STATUS_SUCCESS;int64_tnValue=0;GXInitLib();status=GXOpenDeviceByIndex(1,hDevice);if(status!=GX_STATUS_SUCCESS){std::coutopenerrorstd::endl;return;}}MERCamera::~MERCamera(){GX_STATUSemStatus=GX_STATUS_SUCCESS;if(m_bIsSnaping){EndContinuesMode();}emStatus=GXCloseDevice(hDevice);if(emStatus!=GX_STATUS_SUCCESS){std::coutcloseerrorstd::endl;}//关闭设备库emStatus=GXCloseLib();if(emStatus!=GX_STATUS_SUCCESS){std::coutcloseliberrorstd::endl;}}voidMERCamera::InitCamera(){GX_STATUSstatus=GX_STATUS_SUCCESS;int64_tnValue=0;m_bIsSnaping=false;status=GXGetEnum(hDevice,GX_ENUM_PIXEL_FORMAT,m_nPixelFomat);//获取宽度(需在停止采集状态下设置)status=GXGetInt(hDevice,GX_INT_WIDTH,nValue);m_nImageWidth=(int)nValue;//获取高度(需在停止采集状态下设置)status=GXGetInt(hDevice,GX_INT_HEIGHT,nValue);m_nImageHeight=(int)nValue;//获取图象数据大小status=GXGetInt(hDevice,GX_INT_PAYLOAD_SIZE,nValue);m_nPayLoadSize=(int)nValue;//设置采集模式。一般相机的默认采集模式为连续模式。int64_tnAcqMode=GX_ACQ_MODE_CONTINUOUS;spanstyle=white-space:pre;/spanstatus=GXSetEnum(hDevice,GX_ENUM_ACQUISITION_MODE,nAcqMode);do{m_pBufferRaw8=newBYTE[m_nImageWidth*m_nImageHeight];if(m_pBufferRaw8==NULL){status=GX_STATUS_ERROR;break;}//为存储RGB图像数据开辟空间m_pBufferRGB=newBYTE[m_nImageWidth*m_nImageHeight*3];if(m_pBufferRGB==NULL){status=GX_STATUS_ERROR;break;}//为存储原始图像数据开辟空间m_pBufferRaw=newBYTE[m_nPayLoadSize];if(m_pBufferRaw==NULL){status=GX_STATUS_ERROR;break;}}while(0);if(status!=GX_STATUS_SUCCESS){if(m_pBufferRaw8!=NULL){delete[]m_pBufferRaw8;m_pBufferRaw8=NULL;}if(m_pBufferRaw!=NULL){delete[]m_pBufferRaw;m_pBufferRaw=NULL;}if(m_pBufferRGB!=NULL){delete[]m_pBufferRGB;m_pBufferRGB=NULL;}}}voidMERCamera::StartContinuesMode(){GX_STATU
