Foreword
In the industrial field, the application of functions such as defect detection and target counting is basically a matter of trial and error. There is no specific standard. Standard modules for the functions can be realized by standardizing the input and output interfaces and replacing the process with a script engine.
1. Qt + OpenCV + Halcon
The input and output interface is implemented using Qt + OpenCV. OpenCV needs to convert the collected pictures into Halcon’s image interface for script detection. The script output interface needs to be converted into Qt and OpenCV for drawing the contours and marks of defects or targets.
OpenCV’s Mat to Halcon’s 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( & amp;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( & amp;ho_obj, "byte", w, h, (Hlong)(dataGray));
delete[] dataGray;
}
}
return ho_obj;
}
