Topic

Data collection and labelling has always been a very time-consuming task. For this reason, Televic GSP is investigating different methods of autonomous collection, and autonomous labelling of data. One method of achieving this, is by creating accurate simulations of reality, which can then collect the data themselves.

This internship or thesis topic focusses on simulating vibration behavior of train seats. In a train, multiple seats are connected to a shared support beam (usually behind or underneath the seating). Whenever some form of load is placed atop of the seats, the vibrations in this support beam will change according to the mass-spring rules. By placing an accelerometer on this beam, it should be possible to estimate the kind of load placed on the seats.

In this project the student will use a physics engine, (e.g. PhysX or Unity), to simulate a seating set-up. This would allow us to simulate sensor data, without having to place actual, real-life sensor on trains. Additional advantages of this virtual approach are automatically generating labeled data, optimizing sensor placement, and quick validation of classifier algorithms.

The full scope of this project would depend on if the student chose it as an internship or a thesis. As an internship subject, we would require a proof-of-concept or feasibility study, which is then presented in as a demo at the end of the internship. A thesis first requires a thorough investigation in available modelling techniques and different physics engines. Furthermore, it would be possible to investigate the differences between real-world data and simulated data, as well as the impact of these differences.
