OpenCV中得图可以显示在picture control上，只不过需要把mat对象转成CImage一下，很简单
void MatToCImage( Mat &mat, CImage &cImage)
{
//create new CImage
int width = mat.cols;
int height = mat.rows;
int channels = mat.channels();
cImage.Destroy(); //clear
cImage.Create(width, height,8*channels ); //默认图像像素单通道占用1个字节
//copy values
uchar* ps;
uchar* pimg = (uchar*)cImage.GetBits(); //A pointer to the bitmap buffer
int step = cImage.GetPitch();
for (int i = 0; i < height; ++i)
{
ps = (mat.ptr<uchar>(i));
for ( int j = 0; j < width; ++j )
{
if ( channels == 1 ) //gray
{
*(pimg + i*step + j) = ps[j];
}
else if ( channels == 3 ) //color
{
for (int k = 0 ; k < 3; ++k )
{
*(pimg + i*step + j*3 + k ) = ps[j*3 + k];
}
}
}
}
}
