I'm using the QRCodeDetector class to get a position on a SR Code. So I use the detectAndDecode() method to search for a QR code and it returns a bounding box with the QR code region.

I know how to calculate the center of a square or rectangle. But I don't understand how the bounding box data is set.

since it returrns a vector<Point>, you could try:

vector<Point> pts;
Rect r = getBoundingRect(pts);
Point center(r.x+r.width/2, r.y+r.height/2);

I can't find any getBoundingRect() function.
