Hi @ASSEKO10 and @yuancaimaiyi,

Sorry for the late response, I had little time for this project recently. I guess the question is not actual anymore, but I will answer it in case someone is directed here in the future.

The mentioned error is most likely the result of the algorithm not-detecting the rail pairs correctly. In case there are 0 detected points for the railbed, the 2.5D projection by OpenCV produces this assertion warning. Possible solutions are:

  • Try to manually cut out the railbed a bit more precisely, with minimal surroundings, so the algorithm will find it easier.
  • Use the seeded version of then rail track detection (RailTrackWithSeed algorithm pipeline), in which case the detected cables are passed to the rail detection to better locate the rails afterwards.
