How should I use flann by circular parameters(angle[0..360])?

Note :In other words,the difference between 10 degree & 0 degree is 10 and the difference between 350 degree & 0 degree is also 10.

I do not think that you could make your question more unclear than this ... more ellaboration?

Guess you need to define your own distance function. This is not (easily) possible with OpenCV any more. With a modified and self-build flann-library it is possible though.

I solved the problem with a trick.For angles that are on the border append new feature to query list.

if (new_angle < thresh)
  addNewFeature(x,y,359);
if (new_angle > 360 - thresh)
  addNewFeature(x,y,0);
