I'm creating an orthomosaic of roughly 7000 images, with 90% overlap at most points.
In the past, I've run into issues when running all images as one chunk (especially when they were in long single-image-width lines), so I decided to split them into smaller chunks (in a format to match the rest of my data, usually 50-200 images per chunk).
I split the images, with some overlap for those that intersected several of these chunk boundaries I had decided on. Align images, create low surface mesh, then merge all. In the past I have had the best/quickest results with a low face count mesh as the input for ortho photo.
When I transfer my models, attachment 1 is what the mesh looks like (you can practically see the outline of my chunks in it).
If I recreate a low surface mesh in my merged chunk, the result is image 2 (nm_new_mesh).
Before I continue with the process of creating an orthomosaic, I'd like to know:
1) Of the two meshes, is any one more suited for creating the orthomosaic?
2) Is splitting into chunks totally uneccessary? Will it help or hurt my output?
