Is it too late to ask PFTrack to be my valentine?
The camera track is now completed for the third shot, which earlier had been a challenge to solve due to the small parallax of the objects in frame. So, camera tracking was put on hold after a “decent” one had been created and I went on to building the scene with simple geometry in preparation for the camera texture projections.This simple geometry proved to be more useful than anticipated.
By accident, I had chosen the last node of my previous tracking attempt (the most stable one) when creating a new geometry track node. The new geometry track then used the information from that camera solve with my to-be geometry track. All I had to do was import it and start translating on pixel level until all the previous jitter had been eliminated.
