Recents works


One year after the T3 contest, here are some works from this year and a review of the new tools that we learn to use.

I am still working with Canon S100 and dronemapper intervallometer script, all multirotors are now controled by Pixhawks, the flying wing is controled by an APM 2.5.2

New open sources tools for DEM visualisation :

Visit 2.8.2  (above)

You can get it here :

Really good for generate colored shaders and contours and for very-micro-reliefs analyses



Relief visualisation toolbox

RVT from Dr. Žiga Kokalj - 2014

Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU)
Centre of Excellence for Space Sciences and Technologies (Space-Si)

Get it here :

Here is an exemple of multiple-direction shader (16 directions) at Commes (France) for CNRS and INRAP :

The fallen blockhouse (T3 entry)


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 :

It’s always the same setup, our little quad works very well for automatic flights


Config :

Quadricopter flameweel frame (X450)

ESC 30A simonK

Motors Sunysky X2212 980 kv prop : 10*5

RC T9X open9X - frsky 2.4ghz module

Total flight time : 3min40

Automatic flight : 3min

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


Video of the flight and worflow :

Short version, only results :

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


Blockhaus Sainte Marguerite sur mer from panormandic


Here you can download logs from APM2 and kmz flight path :


Flight path :



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) :
