Orthophoto Result

Hi,

first, sorry for my english is bad.
i want to ask. why the building or tree in the orthophoto look bad.
i choose "high"  for build dense parameter

thanks.

Hello hendra.suse,

Can you also provide the information from Chunk Info (or last page of the Report file), so that we can see all the processing parameters used for processing.

  thanks alexey,

i attach a screenshoot of this chunk info.

Hello hendra.suse,

I don't see the Orthomosaic generated for this project, but anyway, if you wish to get more accurate and detailed results I can suggest the following:

- update PhotoScan to the version 1.2.6,
- Align Photos with High accuracy and 10,000 for tie points limit (if you are using DJI drone, then disable adaptive camera model fitting),
- build dense cloud in Medium quality at least with the aggressive filtering,
- build DEM basing on DEM,
- build orthomosaic using DEM as a surface,
- open orthomosaic in the Ortho view mode (by double-clicking on it's label in the Workspace pane) and inspect the areas that were problematic on the texture.

I hope that it should be considerably better than low-polygonal surface generated based on the low accuracy alignment and unfiltered dense cloud.

Thanks Alexey,

i've try running this project using agisoft 1.2.6 build 2834 in other PC and using High Accuracy but the result of orthophoto is same.
but i has never been build orthomosaic using DEM as a surface, usually i choose Mesh as surface.

and sorry i want to aks other question. you told tie points limit if i using DJI Drone and disable camera model fitting.
in others project i ussually using fixed wing ( skywalker ) and sony aplha 6000 for camera. what should i choose for the parameter on align photo process ( key point limit, tie point limit and adaptive camera model fitting ) ?

Thaks for your response,
Best Regard,
Hendra Suse

Hello Hendra Suse,

If you are building mesh, then make sure that you've used Reset Region option in the Tools menu, so that colored side of the bounding box is parallel to the XY ground plane.

For the alignment parameters I suggest High accuracy, 40 000 key point limit, 10 000 tie point limit, with preselection. If there are no considerable rolling shutter distortions for this camera, then you can enable Adaptive camera model fitting.
