title: matching line segments - robust and fast way
body: <p>I have 2D line segments extracted from a single image data and would like to match with 3D line segments extracted from other source. for that, first I would like to project a 3D line segment to the image space using co-linearity equation (I know exterior orientation parameters). AS both line segments are in same coordinate system now I would like to find the best matching line segment to that line.</p>
  
  <p>I am looking for a fast and robust algorithm to match corresponding line segments in order to update my 3D line segments later. </p>
  
  <p>If any one have an idea on this, please give some suggestions. thanks in advance.</p>
