title: How to find laser cross center with open cv
body: <p>From camera with open cv I can get a red cross (see picture below) , I do not know best method to calculate cross center coordinates (x,y)? We can assume that laser is red.</p>

  <p>Probably I will have to use some kind of object recognition. But I need to calculate it's center and perfomance is important.</p>
  
  <p>Anyone can help ? </p>
  
  <p>I have founded how to find laser pointer (red dot coordinates) by searching most red pixel in the picture but at this case center is not always most red (whole line is red and sometimes cv calculates that it is more red than center).</p>
