[pro] marker tracking pin positions

[Nico]

ability to 'pin' any marker at any frame, and force the tracking to go through pin positions (might require tracking back and forth in the timeline).

At the moment, we can retrack from custom frames, but that is for all markers, and we can only set the start position not the end.

Hello Nico,

Unfortunately currently all markers are tracked simultaneously, but it is possible to input starting and ending frame numbers of marker tracking. In case you need to track markers backwards the frame sequence ending frame number should be lower then starting one.
So if there are any errors in marker tracking you can refine marker positions and restart tracking procedure from that frame.

Hello Nico,

We have added "Pin marker" feature in PhotoScan 0.9.0 build 1561, so it is now possible to start marker tracking procedure from a custom frame with pinned markers.
