ELS offers PhD positions as well as internships. Currently, two PhD students are conducting their research work in close collaboration with our industrial partners on :

  • Study, design and realization of an extended automotive signalization
  • Design and development of an innovative lighting system for autonomous cars

Each year, from March to August, several interns are hosted at ELS laboratories, under the supervision of teachers-researchers from ESTACA and IOGS. Subjects can cover various fields perfectly online with automotive lighting, such as :

  • Videophotometric bench and Image processing for determination of cut-off line: ELS has developed a videophotometric bench to check compliance of passing-beam headlamps with regulation requirements. Verification of the light distribution of the passing beam relies on the cut-off line. Here the work consisted in developing an image processing algorithm to determine the position of the cut-off line on the captured image.
  • Photometric specifications for road projections: The aim of this study wass to provide knowledge on photometric specifications for advanced lighting functions based on road projections, such as the indication of departing situation of a car. For better definition, one needs to specify photometric characteristics of such signals to be better perceived and recognized: contrast, size, dynamics (static/blinking) …
  • Adaptive light projection: projected images on the road need to be corrected from keystone and illumination inhomogeneity. Here the work consisted in developing algorithms to get a keystone-free image with homogeneous illumination on the road. A 9-axis sensor has been mounted on a video projector for instantaneous measurement of the titling angle and hence real-time correction.
  • Digital lighting aiming applied to automatic headlamp levelling: ELS has developed a levelling testbench with mechanical robust design and real-time control based on the integration of angular position sensor and on modelling of vehicle dynamics. Here, a video projector was integrated to the bench with digital aiming based on real-time control of projected images.
  • Video tracking for behavior assessment in UX tests: this work aimed to develop algorithms to track pedestrians in captured videos to get their position and trajectories in a given environment, in order to assess their behavior while subjected to a new lighting function.
  • Development of a virtual reality device for testing new automotive lighting projection: this work consisted in creating immersive Virtual Reality (VR) scenes in order to design UX (User Experience) testing of new automotive lighting functions.
  • Virtual reality and application to simulation and testing of new automotive lighting functions: the work aimed to calibrate VR photometric features (by measuring the relation between VR display and visual perception) for better correlation to the real-world perception. Afterwards, VR tests were performed by simulating and testing a road projection in terms of detection and recognition distances. The goal was to assess the correlation between VR results with those obtained with field tests.
