This is an old German bunker from WW2 fall on the beach at Sainte-marguerite-sur-mer, france. The fire services took down the blockhouse in 1995 because of safety concerns linked to cliff erosion.
If you want to know more about this blockhouse and the cliff :

- Ground station engineer and co-pilot : Raphael Bria
- Cameraman and Blender processing : Stephane Guillet
- Snow covered blockhouse : Julien Beaumel
It’s always the same setup, our little quad works very well for automatic flights

65 good aerial pictures from S100 and 20 ground photos from Lumix G3 are used to compose the model.

Here you can see 3D model on Sketchfab, if it appears black, juste wait for texture :

Green : Auto mode
Red and grey : Stabilize (manual) mode
Yellow : Alt Hold
Orange and blue : Loiter
Garry, if you want to fly over the model with GEFS, just download this KMZ (it could take some time to load into GE) :

Thanks for DIY drone and 3D Robotic for this contest.
It's explain on the video, somes photos were taken from the ground to complete the texture, initially it must be done by the Mobius and the sunex, but photos from Mobius were blurry
Sylvain, nice work on this. Did you just shoot all of the photos directly downwards for this model, or did you also fly around the blockhouse shooting photos at an oblique angle to get the texture on the sides (it looks like there is another set of photos like this in photoscan)? Were the closer photos done in auto mode, or manually?
wow, thanks Sylvian. Well done!!!
Tis true but we can't fly there together! Like you can with GEFS http://www.gefs-online.com/ Looks great on GE
you also can fly over with the model with GE and the flight simulator function (ctrl+shit+A)
Found it, but not your version in 3D yet I guess it will take a while for Google to place it on GE. I wonder if this would be the first 3D item on GE to be mapped and modelled by a drone? Looks like a lovely coastline.
@ Gary, paraglider is the better aircraft for this place !
Mostly 3D Photo Modeling though
@Sylvain, Both! We are focusing mainly on a guide and dedicated forum that will allow for someone with Zero knowledge in this stuff to be able to go step by step to accomplish this with their own work.
@Joshua, does this tutorial will talk about 3D photomodeling or uses for models ?
