/*************************************************************************************************** * * Notes about how to configure your OpenCV environment and project. * 1. You can prepare the required installation package from the official website. https://opencv.org/releases.html * 2. If the *.lib files doesn't exist in the package download, you need to compile by yourself with the CMake tool. * 3. Add the 'bin' folder path to the PATH. * 4. Configure the 'Additional Include Directories', 'Additional Library Directories' and 'Additional Dependencies' for current project property. * * If there is any question or request, please feel free to contact us. ***************************************************************************************************/ #include "MvCameraControl.h" #include "opencv2/imgproc/imgproc.hpp" #include "opencv2/highgui/highgui.hpp" #include <stdio.h> #include <Windows.h> #include <process.h> #include <conio.h> #include "string.h" unsigned int g_nPayloadSize = 0; enum CONVERT_TYPE { OpenCV_Mat = 0, // Most of the time, we use 'Mat' format to store image data after OpenCV V2.1 OpenCV_IplImage = 1, //we may also use 'IplImage' format to store image data, usually before OpenCV V2.1 }; // Wait for key press void WaitForKeyPress(void) { while(!_kbhit()) { Sleep(10); } _getch(); } // print the discovered devices information to user bool PrintDeviceInfo(MV_CC_DEVICE_INFO* pstMVDevInfo) { if (NULL == pstMVDevInfo) { printf("The Pointer of pstMVDevInfo is NULL!\n"); return false; } if (pstMVDevInfo->nTLayerType == MV_GIGE_DEVICE) { int nIp1 = ((pstMVDevInfo->SpecialInfo.stGigEInfo.nCurrentIp & 0xff000000) >> 24); int nIp2 = ((pstMVDevInfo->SpecialInfo.stGigEInfo.nCurrentIp & 0x00ff0000) >> 16); int nIp3 = ((pstMVDevInfo->SpecialInfo.stGigEInfo.nCurrentIp & 0x0000ff00) >> 8); int nIp4 = (pstMVDevInfo->SpecialInfo.stGigEInfo.nCurrentIp & 0x000000ff); // print current ip and user defined name printf("CurrentIp: %d.%d.%d.%d\n" , nIp1, nIp2, nIp3, nIp4); printf("UserDefinedName: %s\n\n" , pstMVDevInfo->SpecialInfo.stGigEInfo.chUserDefinedName); } else if (pstMVDevInfo->nTLayerType == MV_USB_DEVICE) { printf("UserDefinedName: %s\n", pstMVDevInfo->SpecialInfo.stUsb3VInfo.chUserDefinedName); printf("Serial Number: %s\n", pstMVDevInfo->SpecialInfo.stUsb3VInfo.chSerialNumber); printf("Device Number: %d\n\n", pstMVDevInfo->SpecialInfo.stUsb3VInfo.nDeviceNumber); } else { printf("Not support.\n"); } return true; } int RGB2BGR( unsigned char* pRgbData, unsigned int nWidth, unsigned int nHeight ) { if ( NULL == pRgbData ) { return MV_E_PARAMETER; } for (unsigned int j = 0; j < nHeight; j++) { for (unsigned int i = 0; i < nWidth; i++) { unsigned char red = pRgbData[j * (nWidth * 3) + i * 3]; pRgbData[j * (nWidth * 3) + i * 3] = pRgbData[j * (nWidth * 3) + i * 3 + 2]; pRgbData[j * (nWidth * 3) + i * 3 + 2] = red; } } return MV_OK; } // convert data stream in Mat format bool Convert2Mat(MV_FRAME_OUT_INFO_EX* pstImageInfo, unsigned char * pData) { cv::Mat srcImage; if ( pstImageInfo->enPixelType == PixelType_Gvsp_Mono8 ) { srcImage = cv::Mat(pstImageInfo->nHeight, pstImageInfo->nWidth, CV_8UC1, pData); } else if ( pstImageInfo->enPixelType == PixelType_Gvsp_RGB8_Packed ) { RGB2BGR(pData, pstImageInfo->nWidth, pstImageInfo->nHeight); srcImage = cv::Mat(pstImageInfo->nHeight, pstImageInfo->nWidth, CV_8UC3, pData); } else { printf("unsupported pixel format\n"); return false; } if ( NULL == srcImage.data ) { return false; } //save converted image in a local file try { #if defined (VC9_COMPILE) cvSaveImage("MatImage.bmp", &(IplImage(srcImage))); #else cv::imwrite("MatImage.bmp", srcImage); #endif } catch (cv::Exception& ex) { fprintf(stderr, "Exception saving image to bmp format: %s\n", ex.what()); } srcImage.release(); return true; } // convert data stream in Ipl format bool Convert2Ipl(MV_FRAME_OUT_INFO_EX* pstImageInfo, unsigned char * pData) { IplImage* srcImage = NULL; if ( pstImageInfo->enPixelType == PixelType_Gvsp_Mono8 ) { srcImage = cvCreateImage(cvSize(pstImageInfo->nWidth, pstImageInfo->nHeight), IPL_DEPTH_8U, 1); } else if ( pstImageInfo->enPixelType == PixelType_Gvsp_RGB8_Packed ) { RGB2BGR(pData, pstImageInfo->nWidth, pstImageInfo->nHeight); srcImage = cvCreateImage(cvSize(pstImageInfo->nWidth, pstImageInfo->nHeight), IPL_DEPTH_8U, 3); } else { printf("unsupported pixel format\n"); return false; } if ( NULL == srcImage ) { printf("CreatImage failed.\n"); return false; } srcImage->imageData = (char *)pData; // save converted image in a local file try { cvSaveImage("IplImage.bmp", srcImage); } catch (cv::Exception& ex) { fprintf(stderr, "Exception saving image to bmp format: %s\n", ex.what()); } cvReleaseImage(&srcImage); return true; } int main() { int nRet = MV_OK; void* handle = NULL; do { // Enum device MV_CC_DEVICE_INFO_LIST stDeviceList; memset(&stDeviceList, 0, sizeof(MV_CC_DEVICE_INFO_LIST)); nRet = MV_CC_EnumDevices(MV_GIGE_DEVICE | MV_USB_DEVICE, &stDeviceList); if (MV_OK != nRet) { printf("Enum Devices fail!
