Re: [Qgis-user] Batch Aerial Imagery GeoReferencing

[Alexis R.L.]

Greetings,

I'm sure there is a way to use the available flight data to generate
approximate points for each images based on the flight paths and then just
use that to georeference them. It would require some scripting but I don't
see what would prevent any of it if the metadata is reliable.

And option would be to create the coordinates and georeference them with
grass directly as the georeferencer plugin is just an interface as far as I
remember.And there are no bindings for it.

You can contact me as I may be willing to look into this in my free time,
if you want.

Thanks,

Alex

Re: [Qgis-user] Batch Aerial Imagery GeoReferencing

[Kirk Schmidt]

Hi Richard:

It sounds like you are in the world of  manually georeferencing or ortho 
creation.   This would entail identifying ground control points for each 
image and processing.


Assuming you do not need all 6000 images at one time, you could tag each 
image to its central location and then ortho or geo it if it is needed.

Re: [Qgis-user] Batch Aerial Imagery GeoReferencing

[Charles Dixon-Paver]

Just to add to this, QGIS supports using raster images for points with data
driven properties, so with some expression-fu and native tools you can get
decent approximations for images from just exif data. I have wanted to
build a basic template project for the solutions hub but haven't found the
time yet. One issue is that qgis cannot currently distort or "warp" the
raster to the relevant affine parameters, which is where the georeferencing
tool may be used, perhaps using a model. Sadly, scripting the georeferencer
is not that easy, however QGIS does provide a "generate gdal script" for
supported transformations.

There is, however, a community plugin for doing much of this here:
https://verticalphotoplacer.github.io/VerticalPhotoPlacer/

It's a bit clunky to set up and uses external dependencies like exif tools
(3.22 now has a full set of exif expressions so this plugin might be
updated to remove that requirement soon), but it should be functional for
basic usage as I understand the original query. Just be sure to read the
docs.

I'm also not sure how well this would handle large files, you'd probably
need to chunk your data into reasonably sized projects or individual
flights etc.

Just a note that this is in reference to defining and referencing
"footprints" from airstations mostly, although that plugin does provide
some limited visual tools like attempts at mosaicing etc. Pix4D/ AgiSoft
and other commercial software is likely to give you similar results for
mosaics etc from ODM and other SFM tools. If you want to orthorectify you
may be better off just using MicMac directly from commandline, or if you
want to georeference you can simply loop through files with gdal, ossim, or
similar tools.

There are also tools like https://docs.dronedb.app/ for generating image
footprints etc from exif and other tools, although I had pretty limited
success using that toolkit.

Re: [Qgis-user] Batch Aerial Imagery GeoReferencing

[Adam Dershowitz]

One option to consider is Open Drone Map:  https://www.opendronemap.org 
   it is able to take in many Aerial images and 
merge them.  It uses a bunch of open source tools “under the hood” to get this 
done.  It is not QGIS, but the results should play-nice with QGIS.

Re: [Qgis-user] Batch Aerial Imagery GeoReferencing

[Nicolas Cadieux]

Hi,

I would python my way through this using the geotransform functions from Gdal. 
The first step would be to scan the paper index maps, vectorize the index and 
get the geotransform parameters of each file from that. Information could then 
be encode into the files.  I expect the result would be a bit rough and the 
overlapping might not be perfect.  Some adjustments could be done using pixel 
correlation but I have never done that part in python.

[Qgis-user] Batch Aerial Imagery GeoReferencing

[Richard McDonnell]

Afternoon all,
I have access to over 6000 Aerial Images covering Ireland, we also have scans 
of the Flight Paths and Image Orientation and Extents (Scans from Paper Maps)
What I was wondering is if there is a way to Batch Georeference all of these 
Images?
Any Ideas, help, guidance welcome. I have thought about maybe even reverse 
engineering the Flight Plan, then using OpenDroneMap to georeference the Images.
Regards & Thanks,

Richard McDonnell
