Deep Grid Net (DGN): A Deep Learning System for Real-Time Driving Context Understanding
This work addresses motion planning for autonomous driving cars, but it appears incremental as it builds on existing grid map and deep learning methods.
The paper tackles real-time driving context understanding for autonomous vehicles by introducing Deep Grid Net (DGN), which uses deep learning on occupancy grids from Lidar data and Dempster-Shafer theory, and it was evaluated against competing classifiers.
Grid maps obtained from fused sensory information are nowadays among the most popular approaches for motion planning for autonomous driving cars. In this paper, we introduce Deep Grid Net (DGN), a deep learning (DL) system designed for understanding the context in which an autonomous car is driving. DGN incorporates a learned driving environment representation based on Occupancy Grids (OG) obtained from raw Lidar data and constructed on top of the Dempster-Shafer (DS) theory. The predicted driving context is further used for switching between different driving strategies implemented within EB robinos, Elektrobit's Autonomous Driving (AD) software platform. Based on genetic algorithms (GAs), we also propose a neuroevolutionary approach for learning the tuning hyperparameters of DGN. The performance of the proposed deep network has been evaluated against similar competing driving context estimation classifiers.
