1 字符串与HTuple互转

char *pImageName = "D:/data/temp.png";
HTuple hv_path;
hv_path = (HTuple)(pImageName);
cout << hv_path.S() << endl;
string path = hv_path.S();
cout << path<<endl;

2 double与HTuple互转

HTuple hv_data;
hv_data = 10.0;
double data = hv_path.D();
cout << data<<endl;

3 Mat 与 HObject互转

Mat 转 HObject

HObject Cpu_halcon_detect::mat_to_hobject(Mat& image)
{HObject Hobj = HObject();int hgt = image.rows;int wid = image.cols;int i;//  CV_8UC3  if (image.type() == CV_8UC3){vector<Mat> imgchannel;split(image, imgchannel);Mat imgB = imgchannel[0];Mat imgG = imgchannel[1];Mat imgR = imgchannel[2];uchar* dataR = new uchar[hgt*wid];uchar* dataG = new uchar[hgt*wid];uchar* dataB = new uchar[hgt*wid];for (i = 0; i < hgt; i++){memcpy(dataR + wid*i, imgR.data + imgR.step*i, wid);memcpy(dataG + wid*i, imgG.data + imgG.step*i, wid);memcpy(dataB + wid*i, imgB.data + imgB.step*i, wid);}GenImage3(&Hobj, "byte", wid, hgt, (Hlong)dataR, (Hlong)dataG, (Hlong)dataB);delete[]dataR;delete[]dataG;delete[]dataB;dataR = NULL;dataG = NULL;dataB = NULL;}//  CV_8UCU1  else if (image.type() == CV_8UC1){uchar* data = new uchar[hgt*wid];for (i = 0; i < hgt; i++)memcpy(data + wid*i, image.data + image.step*i, wid);GenImage1(&Hobj, "byte", wid, hgt, (Hlong)data);delete[] data;data = NULL;}return Hobj;
}

4 HObject 转 Mat

Mat Cpu_halcon_detect::hobject_to_mat(HObject Hobj)
{HTuple htCh = HTuple();
HTuple cType;
Mat Image;
ConvertImageType(Hobj, &Hobj, "byte");
CountChannels(Hobj, &htCh);
HTuple wid;
HTuple hgt;
int W, H;
if (htCh[0].I() == 1)
{HTuple ptr;GetImagePointer1(Hobj, &ptr, &cType, &wid, &hgt);W = (Hlong)wid;H = (Hlong)hgt;Image.create(H, W, CV_8UC1);uchar* pdata = (uchar*)ptr[0].I();memcpy(Image.data, pdata, W*H);
}
else if (htCh[0].I() == 3)
{HTuple ptrR, ptrG, ptrB;GetImagePointer3(Hobj, &ptrR, &ptrG, &ptrB, &cType, &wid, &hgt);W = (Hlong)wid;H = (Hlong)hgt;Image.create(H, W, CV_8UC3);vector<Mat> vecM(3);vecM[2].create(H, W, CV_8UC1);vecM[1].create(H, W, CV_8UC1);vecM[0].create(H, W, CV_8UC1);uchar* pr = (uchar*)ptrR[0].I();uchar* pg = (uchar*)ptrG[0].I();uchar* pb = (uchar*)ptrB[0].I();memcpy(vecM[2].data, pr, W*H);memcpy(vecM[1].data, pg, W*H);memcpy(vecM[0].data, pb, W*H);merge(vecM, Image);
}
return Image;
}
