Im working on a reconstruction for a few days on and off now. Everytime I go back to my desk and try to align again the whole component gets flipped on the Y axis for no reason.
Usually I would export my imagelist and control points and start from scratch again which is by far not ideal. But since this happened a few times already I would love to go to the bottom of this now.
This what I did so far until the point it breaks:
- imported my lidar files and set Absolute Pose to "fixed" and run a alignment which turns out oriented correctly and kept this component for later comparison
- set the lidar files Lock Pose For Continue = True
- added bulks of images and re-run alignment which was fine in terms of orientation until I ran into alignment issues
- deleted the last component, added control points and re-run the alignment to fix alignment issues, saved new version file
- repeted the last two steps until I shut down my PC
- get back to my PC opened the last RC file and every following component will be flipped
This is what I tried to fix the orientation but with no success:
- delete the cache folder
- delete some of my previous alignments and re-run the alignment
- turned off several control points
- set the lidar files Lock Pose For Continue = False
- deleted all components, cleared cache and re-run just the lidar files but still turns out flipped, which is odd because they have a locked posed
- reset the view
- I compared a few control points from the lidar component and the last messed up component and the last working component are pretty close. Interesting is that the CPs despite having pretty much the same numeric values, are visually somewhere else in the 3D view because of the flip.
Some bits I want to mention:
- if I compare the position of my Lidar-Only-Component with any other which also has images, it seems that the position in the 3D view is shifting slightly which doesnt make much sense to me because the lidar files are locked.
- some of my control points are still with a yellow triangle because these are the areas I am trying to glue together. to all previous component this didnt seem to be an issue.
Some question which might or might not have to do with this issue:
1. Why does it flip in the first place?
2. How is it even possble that the component is flipped when the control points end up at pretty much the same position in terms of numeric values?
