Hello
I try just a poster on a bus map. The problem is that the tracking points are not the entire time in the Picture, but only come back later and disappear. There are a total of 8, at least 2 of them are always in the Picture.
I myself thought it would be s.eifachsten when I on my poster would also be reference, which I as the individual tracking points may assign. But somehow I do not warring out. Previously directed my poster AFX always s.dessen anchor point - but I need more points (point 1 = tracking point 1, etc.).
Perspective distortion klappt not synonymous, because I so only the ECK can track points. The I see but not all at the same time, so the idea with additional score within the image.
Is it clear what I mean? :)
Würd me feedback about you.
mfg, andi
Antwort von glumschie:
track your shot until you see the reference.
shortly before they disappear from the picture, hold down the ALT do with the search-button of the Tracker item. (the 2 outer frame)
It is important that the small cross in the middle will not be moved, but strictly on the spot remains synonymous when it comes out of the picture then rausläuft

I just got a similar problem. I do it so that I only hit the 4 corners with perspective distortion.
In the areas where the vertices are not visible, the first track points are in the process generated keyframes do I get easy (you can simply synonymous not only to calculate, but it works only if the frames in all 4 corners simultaneously vanish). You do not really broke in all frames of keyframe Tracker, in the areas where a vertex is not visible is simply interpolated. If the interpolation is not the perfect result, you can score a few synonymous manual adjust.
I think in the options of the tracker can be synonymous set somewhere that a track point is created only if the "confidence" that the item was correctly recognized, over a certain threshold. I have not yet experimented. If the disappearance of a clear track points Confidence waste is recognizable, it could be the approach then a little more automated.
Just as the first guest has suggested, it is synonymous, I have tried first, but it has not worked well.
Two problems here:
1) The new track area must be located in the Picture exactly parallel to your non-visible point move, the track you actually want. In the perspective distortion is nowhere the case.
2) Even in scenes without perspective distortion had the feeling that the thing was so inaccurate, I next depending on the search to track the item was removed.
Does anyone knows a better solution? Would synonymous keen.
