"Track lost soon after initialisation, reseting..." keeps happening #975

Open Amer-Alhamvi opened 3 years ago

Amer-Alhamvi commented 3 years ago

So I have this problem with different OpenCV versions, and on 2 different platforms. I have boiled it to the following: The while loop in ORBmatcher.cc in line ~180 is always false since the first part "KFit != KFend" is stuck on false. although the second condition "Fit != Fend" toggles no problem.

Thus the return value nmatches = 0, thus the boolean bOK is set to false in line 310 of Tracking.cc and the mState=LOST.

This is how far I could investigate, a newbie here sorry :) If any one knows the solution or have faced a similar problem before I would appreciate your feedback.
