I used a DJI Inspire 2 w/X4S camera to obtain nadir and 45 deg oblique imagery in both directions for the use of reality modeling in ContextCapture. Extensive ground control was placed and recorded to constrain the model. After running a quality check against the DTM, the points were all within 0.1 ft with two exceptions at approx. 0.35 ft. The quality report from ContextCapture also exhibited good results from AT (see below).
When checking elevations from the 3SM to the same DTM used to check GCP quality, the center of the mesh matches in elevation but the extremities of the mesh are upwards of 15 feet apart. The mesh is distorted into a concave shape even though there is control at the extremities of the alignment/mesh.
Could you provide some guidance on how to address this issue? Thank you.
Results should be comparable. Which CC version are you using?
Where are GCPs placed? It is on pavement or on curbs?
I am running CC Update 12. We paint a white X on the pavement for GCPs. I have a meeting setup with a Bentley rep tomorrow so I hope that will shed some light on where I may be going wrong.
Ok, that is clear now run 3. Thank you for your answer.
