Short Description

Over the last years, SLF Davos has been using embedded sensor nodes for measuring trajectories of falling rocks. The acquired data is used to improve simulations of rockfall incidents. However, the employed sensor nodes (StoneNode) have come to their end-of-life and are currently being replaced with better and smaller sensors employing state-of-the-art technology. Over the last months, a new StoneNode has been developed at the IIS, and preliminary field test data has recently been obtained.

In this master project you are going to analyze the obtained data from accelerometers/gyroscopes and pressure sensors, and develop sensor fusion approaches which will allow partial or complete reconstruction of the rock trajectories. Depending on the project progress, novel approaches introducing additional sources of information can be evaluated as well (e.g., videos shot by a drone, 3D terrain models, etc.).
