That's only 12.5 minutes of video at 24 fps and the requirements you've
described sound like a pretty typical camera stabilization problem. Why not

Hi,
I have imported a single wind turbine (dxf) into grass with v.in.dxf
successfully. I need to position it on a map but do not know where to
start.

you assign known location co-ordinates to the base of a wind turbine

Does a vector map display? Are you looking at some of the demo data to make
sure it’s not your map?

Dear all,
sorry to post this issue here, but maybe some of you can help me.
Following Markus Neteler (and other) suggestioins, I was able to
automatically generate a ground control point file for a large set of
images.
Now I have (at least) two directions.
1. rectify the image using i.rectify
2.

Dear all,
Thanks for all your replies.
Considering the answers and comments I complement my request:
1. I have no interest on the spatial coordinates, only need align the
images (so I can use a local coordinate)
2. Although the camera is fixed, there are some variability on the image
positions, th
Hi,
i'm trying to run a python script with GRASS 6.4 on windows,
using an osgeo4w installation and can't find where to put
the GRASS_ADDON_PATH env variable, anyone managed to
set on windows ?

Hello Hamish,
I installed GRASS 7 (following Markus' hint to install GEOS frwk also).
GRASS7 and the GUI start and all seems fine until I try to display a raster map
– it does not display.
I thought that it might be because the mapset was created in an older version
of GRASS (6.4.2) but I star
Hi again,
given that from that tower (or in our cases wildlife foto traps) exactly the
same images are taken at different points in time (assuming cameras are mounted
with fixed angle and so on), one could ideally use one and the same set of GCPs
on all images...
I did not digg through our ima

The request is, I think, related to a stack of images (from a tower)
rather than a flight.

The only problem I see with using Hugin is the lack of orthorectification.
I suppose you must assume planar images.
I hope there will arrive enough fundings to bring bundle adjustment
development on...

Hi Miltinho,
If I understood you correctly, I think we are facing similar challenges,
because we are planning to test our wildlife foto traps in a remote sensing
context where we need to have a proper georeference for each image.
I assume all your images are equal, means they cover the same sur

what's the trouble? maybe we can help.
