Just having some issues regarding Warping and Artifacting when Exporting models as Orthophotos(see attached photo).
We have a 60% overlap on all the photos that are being ran through the Following Batch Process:
Align Photos
- Accuracy: High
- Pair preselection: Ground control
- Point Limit: 40000
- Constrain Features by mask: Yes
Optimise Alignment
Left on default settings
Build Dense Cloud
- Quality: High
- Depth Filtering: mild
- Reuse depth maps: No
Build Mesh
- Surface Type: Height Field
- Source Data: Sparse Cloud
- Interpolation: Enabled(default)
- Face Count Medium
- Custom Face count 200,000
15 GCP's are then added to the file and then put through another batch process with the following parameters:
Optimize Alignment
-Default settings
Build Dense Cloud
- Quality: mild
- Depth Filtering: mild
- Reuse depth maps: no
Build mesh
- Surface type: Height field
- Source data: Dense cloud
- Interpolation: Enabled
- Face count: medium
- Custom Face count: 4,000,000
Once it was exported as a Geotiff it left us with the results in the Top half of the attached photo.
The Bottom Half was rendered with much lower settings and resulted in a significant decrease in the amount of artifacting taking place on the final image.
The Setting for the Process on the bottom half were:
Align Photos
- Accuracy: Low
- Pair Preselection: Ground Control
- Point Limit: 10,000
- Constrain Features by mask: Yes
Optimize Alignment
- Default
Build Mesh
- Surface Type: Height Field
- Source Data: Sparse Cloud
- Interpolation: Enabled(default)
- Face Count Medium
- Custom Face count 200,000
These Parameters resulted with very limited artifacting, but the warping in the photo increased significantly.
We were wondering if anyone had some advise on how we could decrease both artifacting and warping in our orthophoto's
Thanks
