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 :

https://wci.llnl.gov/simulation/computer-codes/visit/

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)

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

Somes works from this year :

Jardeheu (France), 5cm resolution :

Fleury-sur-orne (France), INRAP

Medium neolithic necropolis, 4cm resolution :

Detail of a small neolithic Tertre, 1cm resolution :

Orthophoto and DEM of a very big Tertre, 1cm resolution :

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.

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

APM2 with GPS and compass onboard

Arducopter 3.1 RC5

Lipo 4S 3000mha

Video link : 200mw 5.8 ghz

Camera S100 with CHDK

Mobius camera with Sunnex lens (pictures from Mobius will not be used due to excessive rolling shutter)

Ground station with Asus 1005HA, 3DR 433mhz telemetry and extra deported 433mhz antenna

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 :

Thanks for DIY drone and 3D Robotic for this contest.

Here is our showreel, based on APM.
