CARLA-Loc: Synthetic SLAM Dataset with Full-stack Sensor Setup in Challenging Weather and Dynamic Environments

原文アブストラクト

The robustness of SLAM (Simultaneous Localization and Mapping) algorithms under challenging environmental conditions is critical for the success of autonomous driving. However, the real-world impact of such conditions remains largely unexplored due to the difficulty of altering environmental parameters in a controlled manner. To address this, we introduce CARLA-Loc, a synthetic dataset designed for challenging and dynamic environments, created using the CARLA simulator. Our dataset integrates a variety of sensors, including cameras, event cameras, LiDAR, radar, and IMU, etc. with tuned parameters and modifications to ensure the realism of the generated data. CARLA-Loc comprises 7 maps and 42 sequences, each varying in dynamics and weather conditions. Additionally, a pipeline script is provided that allows users to generate custom sequences conveniently. We evaluated 5 visual-based and 4 LiDAR-based SLAM algorithms across different sequences, analyzing how various challenging environmental factors influence localization accuracy. Our findings demonstrate the utility of the CARLA-Loc dataset in validating the efficacy of SLAM algorithms under diverse conditions.
