前言
在工业领域中，缺陷检测、目标计数等功能的应用，其过程基本都是见招拆招，没有一个具体的标准，把输入输出接口标准化，过程用脚本引擎代替就可以实现功能的标准模块。
一、Qt + OpenCV + Halcon
输入输出接口采用Qt + OpenCV来实现，OpenCV需要将采集到的图片转为Halcon的图像接口用于脚本检测，脚本输出的接口需要转换为Qt和OpenCV，用于绘制缺陷或目标的轮廓和标记。
OpenCV的 Mat 转 Halcon 的 HObject：
HObject HMatToHObject(Mat image)
{
HObject ho_obj=HObject();
if(image.empty())
return ho_obj;
if(3==image.channels())
{
int w=image.cols;
int h=image.rows;
if(image.depth()==CV_8U)
{
vector<cv::Mat> ichannels;
cv::Mat imagB;
cv::Mat imagG;
cv::Mat imagR;
cv::split(image, ichannels);
imagB=ichannels.at(0);
imagG=ichannels.at(1);
imagR=ichannels.at(2);
uchar* dataRed=new uchar[w*h];
uchar* dataGreen=new uchar[w*h];
uchar* dataBlue=new uchar[w*h];
for(int i=0;i<h;i++)
{
memcpy(dataRed + w*i, imagR.ptr() + imagR.step*i, w);
memcpy(dataGreen + w*i, imagG.ptr() + imagG.step*i, w);
memcpy(dataBlue + w*i, imagB.ptr() + imagB.step*i, w);
}
GenImage3(&ho_obj, "byte", w, h, (Hlong)(dataRed), (Hlong)(dataGreen), (Hlong)(dataBlue));
delete[] dataRed;
delete[] dataGreen;
delete[] dataBlue;
}
}
else if(1==image.channels())
{
int w=image.cols;
int h=image.rows;
if(image.depth()==CV_8U)
{
uchar* dataGray=new uchar[w*h];
for(int i=0;i<h;i++)
memcpy(dataGray + w*i, image.ptr() + image.step*i, w);
GenImage1(&ho_obj, "byte", w, h, (Hlong)(dataGray));
delete[] dataGray;
}
}
return ho_obj;
}
输入-脚本-输出相关代码：
try
{
HObject ho_ImageIn, ho_RegionIn, ho_RegionOn, ho_Chamber;
HTuple hv_Objs, hv_Phi;
HTuple hv_Rows, hv_Cols, hv_Area, hv_Row, hv_Column;
//图像Mat转换
ho_ImageIn=HMatToHObject(param->image);
GenEmptyObj(&ho_RegionIn);
GenEmptyObj(&ho_RegionOn);
if(isOK)
{
//引擎
m_HdevHpdc.SetInputIconicParamObject("ImageIn", ho_ImageIn);
m_HdevHpdc.SetInputIconicParamObject("RegionIn", ho_RegionIn);
//执行Haclon程序
m_HdevHpdc.Execute();
//输出结果
ho_RegionOn=m_HdevHpdc.GetOutputIconicParamObject("RegionOn");
try
{
CountObj(ho_RegionOn, &hv_Objs);
hv_Objs = hv_Objs.Length()!=1 ? (int)0 : hv_Objs;
for(int i=1;i<=hv_Objs.I();i++)
{
//缺陷坐标、面积
SelectObj(ho_RegionOn, &ho_Chamber, i);
AreaCenter(ho_Chamber, &hv_Area, &hv_Row, &hv_Column);
OrientationRegion(ho_Chamber, &hv_Phi);
OutPatchResult result;
result.col=(float)hv_Column.D();
result.row=(float)hv_Row.D();
result.angle=(float)hv_Phi.D()*180/QM_PI;
result.area=(float)hv_Area.D();
GetRegionContour(ho_Chamber, &hv_Rows, &hv_Cols);
for(int i=0;i<hv_Cols.Length();i++)
{
result.contour.push_back((float)hv_Cols[i].D());
result.contour.push_back((float)hv_Rows[i].D());
}
importApi->results.push_back(result);
//记录总面积和数量
Area += hv_Area.D();
Count++;
}
//加载成功
inter->hdevOk=true;
inter->hdevError=QString("RegionNum: %1; Area: %2; Time: %3ms")
.arg(Count)
.arg(Area)
.arg((double)clock()-Times);
}
catch(HOperatorException &hv_Except)
{
isOK=false;
inter->hdevOk=false;
inter->hdevError=QString("[error: EngineOperator=%1;]").arg(hv_Except.ErrorMessage().Text());
}
}
}
catch(HDevEngineException &hv_Except)
{
isOK=false;
inter->hdevOk=false;
inter->hdevError=QString("[error: EngineDetect=%1;]").arg(hv_Except.Message());
}
Halcon加载脚本文件相关代码：
bool TB_HaclonEngin::loaded()
{
bool isOK=true;
HaclonEnginImport* importApi=&api.input;
try
{
//初始化
this->released();
QFile file(importApi->inter.hdevPath);
isOK = file.exists() ? isOK : false;
if(isOK)
{
//加载
m_HdevProgram.LoadProgram(importApi->inter.hdevPath.toLocal8Bit().data());
//变量名
m_HdevParamNames=m_HdevProgram.GetCtrlVarNames();
//对象名
m_HdevIconNames=m_HdevProgram.GetIconicVarNames();
//函数名
m_HdevFunNames=m_HdevProgram.GetLocalProcedureNames();
//第一个子函数变量(runApi)
HTuple funName=m_HdevFunNames.TupleSelect(HTuple(0));
//进程
m_HdevHpd=HDevProcedure(m_HdevProgram, funName.ToSArr()->Text());
m_HdevHpdc=m_HdevHpd.CreateCall();
importApi->inter.hdevOk=true;
importApi->inter.hdevError=QString::fromLocal8Bit("Load: %1").arg(importApi->inter.hdevPath);
}
}
catch(HDevEngineException &hv_Except)
{
isOK=false;
importApi->inter.hdevOk=false;
importApi->inter.hdevError=QString("[error: EngineLoad=%1;]").arg(hv_Except.Message());
}
return isOK;
}
二、QScintilla扩展包
QScintilla工具可实现Halcon脚本的颜色编译，包括关键字的提示，和语法错误信息提示等等。
