一、准备工作

1）安装好halcon，确保halcon的c++的调用是正常的

2）编译好opencv

上面的两个步骤，均可以参考我的两个博文完成：

Halcon在linux及ARM上的安装及c++工程化_halcon linux-CSDN博客

RK3588上编译opencv 及基于c++实现图像的读入-CSDN博客 

二、代码准备

2.1 基于c++的opencv和halcon之间的图像的转换代码

// 将halcon图像转换为opencv的图像
Mat HImageToMat(HObject &imgHalcon)
{HTuple channels;HString cType;cv::Mat Image;ConvertImageType(imgHalcon, &imgHalcon, "byte");CountChannels(imgHalcon, &channels);Hlong width = 0;Hlong height = 0;if (channels[0].I() == 1){HImage hImg(imgHalcon);void *ptr = hImg.GetImagePointer1(&cType, &width, &height);//GetImagePointer1(Hobj, &ptr, &cType, &wid, &hgt);int W = width;int H = height;Image.create(H, W, CV_8UC1);unsigned char *pdata = static_cast<unsigned char *>(ptr);memcpy(Image.data, pdata, W*H);}else if (channels[0].I() == 3){void *Rptr;void *Gptr;void *Bptr;HImage hImg(imgHalcon);hImg.GetImagePointer3(&Rptr, &Gptr, &Bptr, &cType, &width, &height);int W = width;int H = height;Image.create(H, W, CV_8UC3);vector<cv::Mat> VecM(3);VecM[0].create(H, W, CV_8UC1);VecM[1].create(H, W, CV_8UC1);VecM[2].create(H, W, CV_8UC1);unsigned char *R = (unsigned char *)Rptr;unsigned char *G = (unsigned char *)Gptr;unsigned char *B = (unsigned char *)Bptr;memcpy(VecM[2].data, R, W*H);memcpy(VecM[1].data, G, W*H);memcpy(VecM[0].data, B, W*H);cv::merge(VecM, Image);}return Image;
}//OpenCV Mat -> Halcon HObject​
HObject MatToHImage(Mat &imgMat)
{HObject Hobj = HObject();int height = imgMat.rows;int width = imgMat.cols;int i;//  CV_8UC3if (imgMat.type() == CV_8UC3){vector<cv::Mat> imgchannel;split(imgMat, imgchannel);cv::Mat imgB = imgchannel[0];cv::Mat imgG = imgchannel[1];cv::Mat imgR = imgchannel[2];uchar* dataR = new uchar[height * width];uchar* dataG = new uchar[height * width];uchar* dataB = new uchar[height * width];for (i = 0; i<height; i++){memcpy(dataR + width*i, imgR.data + imgR.step*i, width);memcpy(dataG + width*i, imgG.data + imgG.step*i, width);memcpy(dataB + width*i, imgB.data + imgB.step*i, width);}GenImage3(&Hobj, "byte", width, height, (Hlong)dataR, (Hlong)dataG, (Hlong)dataB);delete[]dataR;delete[]dataG;delete[]dataB;}//  CV_8UCU1else if (imgMat.type() == CV_8UC1){uchar* data = new uchar[height*width];for (i = 0; i<height; i++)memcpy(data + width*i, imgMat.data + imgMat.step*i, width);GenImage1(&Hobj, "byte", width, height, (Hlong)data);delete[] data;}return Hobj;
}

2.2 创建一个总执行的cpp

HalconDemo.cpp

#include <iostream>#include <halconcpp/HalconCpp.h>
#include <opencv2/opencv.hpp>using namespace HalconCpp;
using namespace std;
using namespace cv;// 将halcon图像转换为opencv的图像

{HTuple channels;HString cType;cv::Mat Image;ConvertImageType(imgHalcon, &imgHalcon, "byte");CountChannels(imgHalcon, &channels);Hlong width = 0;Hlong height = 0;if (channels[0].I() == 1){HImage hImg(imgHalcon);void *ptr = hImg.GetImagePointer1(&cType, &width, &height);//GetImagePointer1(Hobj, &ptr, &cType, &wid, &hgt);int W = width;int H = height;Image.create(H, W, CV_8UC1);unsigned char *pdata = static_cast<unsigned char *>(ptr);memcpy(Image.data, pdata, W*H);}else if (channels[0].I() == 3){void *Rptr;void *Gptr;void *Bptr;HImage hImg(imgHalcon);hImg.GetImagePointer3(&Rptr, &Gptr, &Bptr, &cType, &width, &height);int W = width;int H = height;Image.create(H, W, CV_8UC3);vector<cv::Mat> VecM(3);VecM[0].create(H, W, CV_8UC1);VecM[1].create(H, W, CV_8UC1);VecM[2].create(H, W, CV_8UC1);unsigned char *R = (unsigned char *)Rptr;unsigned char *G = (unsigned char *)Gptr;unsigned char *B = (unsigned char *)Bptr;memcpy(VecM[2].data, R, W*H);memcpy(VecM[1].data, G, W*H);memcpy(VecM[0].data, B, W*H);cv::merge(VecM, Image);}return Image;
}//OpenCV Mat -> Halcon HObject​
HObject MatToHImage(Mat &imgMat)
{HObject Hobj = HObject();int height = imgMat.rows;int width = imgMat.cols;int i;//  CV_8UC3if (imgMat.type() == CV_8UC3){vector<cv::Mat> imgchannel;split(imgMat, imgchannel);cv::Mat imgB = imgchannel[0];cv::Mat imgG = imgchannel[1];cv::Mat imgR = imgchannel[2];uchar* dataR = new uchar[height * width];uchar* dataG = new uchar[height * width];uchar* dataB = new uchar[height * width];for (i = 0; i<height; i++){memcpy(dataR + width*i, imgR.data + imgR.step*i, width);memcpy(dataG + width*i, imgG.data + imgG.step*i, width);memcpy(dataB + width*i, imgB.data + imgB.step*i, width);}GenImage3(&Hobj, "byte", width, height, (Hlong)dataR, (Hlong)dataG, (Hlong)dataB);delete[]dataR;delete[]dataG;delete[]dataB;}//  CV_8UCU1else if (imgMat.type() == CV_8UC1){uchar* data = new uchar[height*width];for (i = 0; i<height; i++)memcpy(data + width*i, imgMat.data + imgMat.step*i, width);GenImage1(&Hobj, "byte", width, height, (Hlong)data);delete[] data;}return Hobj;
