I'm writing a program in opencv that stitches aerial images taken by a drone. The problem is that the stitch,after a certain point, start to "curving", so my homography matrix will be messed up and I can't stitch anything more. There's a way in openv to do images orthorectivication without gps or DEM parameters? If not in opencv, there's a library easily integrable with opencv?

Thanks! PS: I'm programming in C++

  • use bundle adjustment or search literature for different methods to reduce drift – Micka Jun 16 '15 at 16:02
  • I've done a search for the bundle adjustment, and I think it isn't very clear.. I'm implementing manually the stitching pipeline but I can't pass my feature vector (calculated with orb) in the bundle adjustment function. There's a good tutorial for opencv bundle adjustment? – bjorn Jun 16 '15 at 21:12
  • maybe you have to implement bundle adjustment yourself – Micka Jun 17 '15 at 05:00
  • there's a paper or some pseudocode I can refer to? – bjorn Jun 17 '15 at 10:20
