The images have no location data - just a csv file with each image that has an altitude of ‘12000’ and blank cells for lat. and long.
I don’t need the image to be georeferenced yet - I’m hoping I can stitch them together and then georeference/rubber-mat the final product to some GCPs (road corners, etc.). I was hoping to avoid having to try and add a GCP for every historical image as it’s quite difficult to place them.
I’ve attempted to import the images into WebODM and run a task at the default settings. I’ve also tried to set matcher-neighbor and matcher-distance to 0 to disable any attempt to use EXIF data but still get the message “An orthophoto could not be generated. To generate one, make sure GPS information is embedded in the EXIF tags of your images, or use a Ground Control Points (GCP) file”
I would paste the entire task output but it’s truncated at 500 lines (there must be a way around this?) and hopefully, my question can be answered without it (although I appreciate it could help).
I’m using WebODM through Docker/Google Chrome on a 2012 Macbook Pro. I’ve made numerous successful orthophotos on my machine using imagery from a DJI Inspire 2.
Surely there is a way to create a non-georeferenced orthophoto? Any help would be greatly appreciated!!
I had a go with this yesterday and managed to create a comprehensive set of GCPs covering the area I’m trying to stitch. I then ran the process with: Options: fast-orthophoto: true, skip-3dmodel: true, rerun-from: dataset
Unfortunately the process has stalled at:
[INFO] running pdal pipeline -i /tmp/tmpVAmXg3.json > /dev/null 2>&1
The clock has continued to run (is now at 13 hours) but there has been no progress. I think it actually reached this stage about 30 mins in. I’ve had this problem in the past and thought it was something to do with overloading my computer, so I restricted Dockers access to 7 (of my 8) CPU threads and 14GB (of my 16GB) of RAM. This seemed to help with the smaller things I was processing but maybe it wasn’t a solution (?).
I had another go with half of the dataset but ran into this problem - ‘Exception: Child returned 1’
