Financed by the French Research Agency (Agence Nationale de la Recherche), this postdoctoral research fellow position will work in the framework of the project ReSilientGAIA (Reliable Positioning System for Soft Mobility Safety Enhancement with a Green AI Approach). The objective of this project is to add safety control in a new reliable positioning algorithm based on multisensory fusion for soft mobility users (pedestrian, bikes, e-scooters, etc). The sensors considered in this project include Global Navigation Satellite Systems (GNSS), Inertial Navigation System (INS), magnetometer and barometer. Our ambition is to design new approaches based on AI to build physical models that describe the signal perturbations in complex urban environments. By improving the safety and reliability of the positioning system for soft mobility, this project contributes to the mobility transition strategy toward lower carbon emissions.
The postdoctoral fellowship will work on the following missions:
- Vehicular AI model training for GNSS measurement anomaly detection and positioning uncertainty estimation. To do this, the existing labeled dataset will be used in priority. Potential environmental features (such as urban morphological indicators) will be considered using the 3D city model.
- Propose an approach of automatic data augmentation and continuous learning for the pre-trained vehicle anomaly detection model.
- Soft mobility data labeling technique development using fisheye camera: propose a method to further evaluate and improve the accuracy of the labeling technique developed in , which uses image segmentation and satellite projection.
- Once the labeling technique is developed, a soft mobility multiple-sensor dataset will be constructed. The soft mobility considered in the project includes mainly pedestrians, bikes and e-scooters.
- Analyze the feasibility and the possible approaches of the transfer learning between vehicle and pedestrian.
