The artifacts can be minimized with good dataset. You could generally increase your flight height and the image overlap to minimize the effect. For your quality report, I don’t see any issue while processing. I would suggest you to try the below calibration methods and see if that is helpful.
- Calibration Method: Alternative (Optimized for aerial nadir images with accurate geolocation, low texture content and relatively flat terrain, fields for example)
- Internal Parameters Optimization: All Prior (Forces the optimal internal parameters to be close to the initial values.)
- Increase the image scale to full during step 2. Point, Cloud and Mesh.
I would also recommend you to go through our support article on Distortions and Artifacts in the Orthomosaic.
