title: How to position a car in image processing (computer vision)?
body: <p>I would like to locate a car (front center point x,y) using a high resolution single camera. The camera setup is fixed at 1-2m high, and tilted around 25 degrees. The camera can provide images in where the front side of the car is visible. The intrinsic and extrinsic parameters are known.</p>
  
  <p>So far, I tried to detect the headlights and number plates. Issues... Headlights are not detected as blobs all the time. The shape of the headlights are changing depending on the distance. Also, the number plate is not visible in the dark. </p>
  
  <p>Is there a robust algorithm to detect a car? or to detect headlights? or detect number plate?How could I proceed? </p>
  
  <p>Thanks in advance,</p>
