In 2014, as a collaboration between QUT and the University of Los Andes, I and 6 other students traveled to the Quinchia region of Colombia, to implement self-designed 3D mapping software.
We adapted Point-cloud library to interface with an Xbox Kinect camera, and live-render images on a computer we had assembled inside a backpack.
This meant we had a cost-effective and wearable 3D mapping device, specifically designed for ease of implementation in developing communities.
While in Quinchia, we used the device to 3D map mine-shafts, and help annotate safety concerns. Alongside this, we also developed low-cost water filtration devices specific to the mercury in the local water supply. Read about the project here.
