Topographic 3D Map & Video Simulator

By taking photographs from different heights and positions regarding the plane parallel to the ground we can obtain a map. This process is known as 3D mapping. Using either the programme Autodesk Remake or 123D Catch we can organise these pictures in such a way that they form a 3D net similar to the terrain. The biggest difficulty we faced was the fact that we needed to take pictures from places where the angle made with the ground by the satellite is different. In a free fall, this would turn out to be impossible, but with the help of the paraglider we attached, the matter is solved. By following a helicoidal path or trajectory with the CanSat, we can solve this problem. The camera will be able to take pictures from different angles and this will open up the possibility to generate a 3D map.

This 3D map will be the base to our 3D Video-Simulation. We will render the path followed by the CanSat (this would be calculated before-hand, through the GPS & pressure data, collected in a chart). Along with the rendered Cansat we will show a tag with the data regarding the position of the satellite within the simulation, and to make it easier to follow, graphs with this data will be shown likewise at the same time.

Lastly, once the ground has been analysed and the team has selected a spot deemed correct for the landing of a probe, another 3D animation will be put together for further projection of the probe’s calculated landing.
