I have processed a PPK flight using a powered lift aircraft fitted with a modified Sony 5100 (Foxtech Map01 with 16mm Sony lens) and am getting unusual results with the point cloud - it is very spiky/noisy/bumpy in areas which should be very flat/smooth.
The following image illustrates this:
There is nothing in the Quality report to suggest what could be causing this. Some settings we have experimented with include
- Image scale - Half image size
- Multiscale - ticked
- Point Density - Optimal and Low
- Minimum number of matches - 3 and 4
- processing using non-geotagged and geotagged imagery
Thinking it is an image matching issue, perhaps something happening with geotagging?
We have done other projects using the same equipment and workflows and have not experienced this issue before… any help would be much appreciated!
