Filmed a long stretch along the water with the Mavic 2 pro. Pix4Dmapper bent the model when creating control points. Because of what it turned out that duplicate surfaces were created at different heights and the vertical elements ceased to be vertical.
Would it be possible that you upload the .pdf quality report so we get an overview of the project?
Narrow corridor project are, in general, more prone to bending and breaking we recommend:
- Using highly accurate image geolocation (RTK or PPK drone) is recommended.
- It is highly recommended to have GCPs well distributed in the model: Number and distribution of ground control points (GCPs) in corridor mapping.
