VC++联合HALCON多线程处理图像

本文，通过实际代码演示图像的多线程处理，以下为具体的流程。

#define THREAD_CNT 60//定义一个常量，它要比线程的个数还要大CEvent eFaceProcThread[THREAD_CNT];static UINT FaceProcThread(LPVOID lParam){POUTPUTDATA pParam = (POUTPUTDATA)lParam;//处理图像，这里是基于形状的模板匹配找到对应位置，再把模板仿射到找到的位置保存到ho_RegionAffineTransPartialRegional(pParam->ho_Image,pParam->ho_ObjectSelected,pParam->ho_RegionUnion,&pParam->ho_RegionAffineTrans,pParam->hv_ModelID);eFaceProcThread[pParam->Index].SetEvent();return 0;}int ResistanceFind(HObject  ho_Image,PINPUTDATA pInputData,POUTPUTDATA pOutputData){// Local iconic variablesHObject  ho_RegionErosion, ho_RegionUnion;HObject  ho_ObjectSelected;// Local control variablesHTuple  hv_Width, hv_Height, hv_WindowHandle;HTuple  hv_Number, hv_ModelID, hv_Area, hv_Row1, hv_Column1;BlobDemo(ho_Image, &ho_RegionErosion, &ho_RegionUnion, &hv_Number, &hv_ModelID);AreaCenter(ho_RegionUnion, &hv_Area, &hv_Row1, &hv_Column1);{int end_num = hv_Number;OUTPUTDATA stOutputData[THREAD_CNT];//结构体for(int i = 0; i < end_num;i++){//BLOB分析获取单个识别区域SelectObj(ho_RegionErosion, &ho_ObjectSelected, i+1);stOutputData[i].Index = i;//第几个数据stOutputData[i].ho_Image = ho_Image;//原图stOutputData[i].ho_ObjectSelected = ho_ObjectSelected;//单个线程要处理的区域stOutputData[i].ho_RegionUnion = ho_RegionUnion;//模板轮廓，在匹配获得区域后，就可以把模板轮廓仿射盖上去stOutputData[i].hv_ModelID = hv_ModelID;//模板IDGenEmptyObj (&stOutputData[i].ho_EmptyObject);//新建一个空数据//打开线程，由于是循环开线程故这里会是多线程AfxBeginThread(FaceProcThread,&stOutputData[i],THREAD_PRIORITY_IDLE,0,0);}//遍历等待线程实行完成for(int j = 0; j < end_num;j++){WaitForSingleObject(eFaceProcThread[j].m_hObject,-1);}HObject ho_EmptyObject;GenEmptyObj(&ho_EmptyObject);//新建一个空数据//遍历把各线程找到的区域合并到ho_EmptyObjectfor(int j = 0; j < end_num;j++){ConcatObj(ho_EmptyObject, stOutputData[j].ho_RegionAffineTrans, &ho_EmptyObject);}DispObj(ho_EmptyObject, pOutputData->hWndID);//显示通过多线程找到的区域}return 0;}
