title: How can I convert GPS coordinate to pixel on the screen in OpenCV?
body: <p>I'm writing an application in c++ which gets the camera pose using fiducial markers and also as input get a lat/lon coordinate in the real world and as output streams a video with X marker which shows the location of the coordinate on the screen.</p>
  
  <p>When I move my head , the X stays in the same place spatially (because I know how to move it on the screen based on the camera pose or even hide it when I look away.</p>
  
  <p>My only problem is to convert the coordinate from real life to coordinate on the screen.</p>
  
  <p>I know my own gps coordinate and the target gps coordinate.
  I also have the screen size (height / width) .</p>
  
  <p>How can I in openCV translate all these to x,y pixel on the screen ? </p>
