Massive Artefacts in Orthofoto & 3D model export
« on: July 23, 2016, 04:18:31 PM »
Especially when we do processing of aerial survey over buildings and trees I have a lot of artefacts on exporting the Orthofotos...

building lines not clear, roofs very bumpy, solar panels not clear....

on average mode I have strong blending, while in mosaic I have holes...

How can I optimize this errors?
Thanks

Hello GrinGEO,

Please post the screenshots demonstrating the problem and specify the processing settings used.

As adviced from you I have installed a new 1.2.5 version on a test computer and we could process better the images, also becouse we used Agisoft Lens and importet the calibration. Thank you for your help in this

but still I have some issues to resolve, for example a lot of artefacts especially on buildings & trees

Dear Alexey
Here a Orthomosaic from a Sub-Chunk.

http://files.viramedia.de/Ronsberg.jpg

Full-Model can be seen here
https://sketchfab.com/models/9e6487fdb9a9456eaac1f82b8ea3b9e0

The process was:

1. importing about 300 images with Geotag
2. Agisoft Lens Cal saved calibration settings
3. Photoscan Camera calibration loaded Agisoft Lens XML file
4. Workflow Alignement
4. Optimize all camera settings except P3 P4
5. Cleaning spae cloud with wrong pixels as good as possible
6. creating dense point cloud
7. creating mesh high
8. creating orthomosaic

Have I done something wrong?
Thanks for helping
