title: Panorama of cylinder
body: <p>I want to create 2D panorama of lateral surface of a metallic(painted/otherwise) cylindrical object which can have defects such as scratch or a dent. I captured a video of 300 frames with appropriate ROI of the same. Now I am trying to stitch two continuous frames but  there are no control points (not identifiable) since the surface is uniform so you don't know where the 1st column of second frame lies in the 1st frame. Moreover, the intensity values of a pixel tend to vary over two continuous frames due to high reflective nature of metal surface. Each frame has distortion too cuz of the curved nature of the surface. 
  As an alternative method I tried using multiple cams but I am loosing the 'data' at the two ends of a frame.</p>
