In my previous project, we did manual calibration assuming pinhole model. However, for real world cameras, distortions are always present to a degree. In this project we utilize OpenCV camera calibration method that deals with radial and tangential distortions. ...
In this project, I use simple manual camera calibation method. The setup is as follows: Assuming pin hole camera, we can utilize similar triangle methods(see below), and can come up with focal lengths equation: # fx = (dx/dX) * dZ , fy = (dy/dY) * dZ where dX, dY are the physical length & width of the object in view and dZ is the distance from object to camera. dx and dy are the corresponding pixel width & height of the object...
