Rapid Orthomosaic
« on: May 24, 2022, 12:55:42 PM »
Hi everyone,

I am looking for a method to generate a quick orthomosaic, so color can be checked and adjusted prior to the final mosaic.

I have 5400 images from FujiFilm GS100 100 MegaPixels)

I have psx project with 1100 of the 5400 images. It is aligned, optimised, Dense Pt Cld, Mesh, all ready to go to mosaic - that takes 7 hours.
But the colors differences between images are large due different dates, sun-angle, atmospheric conditions, etc.

I made some low resolution images, and made a new psx with those.
I did the  usual process and could generate a low-res mosaic in 2 minutes

I would like to import the EO (XYX/OPK.csv) from the accurate high-resolution psx - in place of the whole allign/optimise etc process with the low-res images

I hope to import and accept the EO
Also import a mesh or DEM, create a camera calibration, then run mosaic

But not sure how to tell metashape to accept the imported EO.


MetaSHape 1.7.5 build 13229 (64 bit)

regards

Murray

Hello MurrayW,

you can look at  https://github.com/agisoft-llc/metashape-scripts/blob/master/src/quick_layout.py. This let's you set the EO of images according to imported reference values (XYZ YawPitchRoll)...

it should get you going
