本文介绍如何将BYTE类型的数据转换为OpenCV中的Mat格式和HALCON中的Hobject格式，包括灰度图和彩色图的处理过程，并展示了使用这些格式进行图像显示的方法。

BYTE转换成Mat格式

int nImgMatType;
int nTmgMatType;
if ( nImgType == 0 )
{
nImgMatType = CV_8UC1;
}
else if ( nImgType == 1 )
{
nImgMatType = CV_8UC3;
}
else
{
return 1;
}

if ( nTmgType == 0 )
{
nTmgMatType = CV_8UC1;
}
else if ( nTmgType == 1 )
{
nTmgMatType = CV_8UC3;
}
else
{
return 1;
}

CvSize size;
size.width = (int)((fImgWidth*1000+1)/1000);
size.height = (int)((fImgHeight*1000+1)/1000);

CvSize sizeTemp;
sizeTemp.width = (int)((fTmgWidth*1000+1)/1000);
sizeTemp.height = (int)((fTmgHeight*1000+1)/1000);

Mat imgMat(size.height, size.width, nImgMatType, image_data);
Mat tmgMat(sizeTemp.height, sizeTemp.width, nTmgMatType, temp_data);

namedWindow("Source");
imshow("Source", imgMat);
namedWindow("Template");
imshow("Template", tmgMat);
cvWaitKey();
cvDestroyAllWindows();

BYTE转换成Hobject格式
