Which is the best workflow to create thermal orthomosaics?
« on: October 30, 2017, 10:33:12 PM »
I would like to know, if someone have experience with this, how to create a good thermal orthomosaic with Agisoft Photoscan, is better use the sparse cloud or the dense cloud? if is the dense cloud, wich mode: aggressive, mild or moderate? and finally with the mesh: height field or arbitrary?

Thanks.

If you have some data, run these 8 tests on a small subset of images, fill in the results column at the end, and let us know! Lead the way!

A few months ago, I've been working hard for a good result of a thermal orthomosaic. So these were my best results at the end.

Thermal color

I will also upload the report of this project, so that you can read which settings I did use.

That would be awesome.

Beautiful results!

This was my workflow in Photoscan to create the orthomosaic, I want to see yours!! I had big distortions especially on the borders. I don´t know if you solved that issue.

We use ICI thermal cameras and make thermal mosaics.

Align
Add GCP (we made targets out of 2 emergency space blankets and a visual target on top)
(I have build dense point cloud and ran my mosaics with and without it, prior to adding the mesh, sometimes it made it better other times it did not - just depends, I use aggressive rarely the milk or moderate)
Import RGB Mesh (if you have an RGB flight)
Build DEM (arbitrary since our Z field is not height, but temperature)
Build Ortho (average blending mode is better than mosaic blending mode for us)

Normally we have a corresponding RGB flight that I export its model/mesh to use as a surface in the thermal. The only time I did not is when the thermal flight is pretty low 30 m AGL for example.

Hi JUANCORDOBA

Could you please share your workflow again? Interested to see how you created the orthomosaic, I am struggling to do one now with Flir Duo Pro R.

Thanks

Hi!

Please, can you give a working links for this files, if possible.

I'll be very appreciative, cause I have a problems with aligning FLIR Duo Pro R 640 images in Agisoft too

Thanks,
Andriy!
