I collected around 2000 drone images over 200 ha. My computer does not have the resources to render one large orthomosaic at once, so I decided to split my dataset into 8 and produce 8 different orthomosaics. I am using
WebODM for my image processing.
Because I did not use GCP's, all my 8 orthomosaics do not align properly with one another, and I want to merge them into one large orthomosaic.
Question: What software/technique can I use to align my 8 orthomosaics so I can merge them into one?
I have tried:
I found this Python library
arosics (https://pypi.org/project/arosics/) to co-register overlapping imagery. However, I cant get it to work with my drone orthomosaics. I believe it has to do with the pixel type, but not sure. I can share the code and output here if someone is interested.
I know cloud processing is a solution, but I do not have the funds at the moment to make this a viable solution.
