ParkingScenes: A Structured Dataset for End-to-End Autonomous Parking in Simulation Scenes
Autonomous parking has emerged as a vital yet complex challenge for intelligent driving systems, particularly in densely populated urban areas where space is often limited. Precise maneuvering and control are essential to navigate these constrained environments effectively. Despite recent advances in end-to-end learning methodologies, the field has been hindered by a lack of high-quality, structured datasets specifically designed for parking scenarios. To bridge this gap, researchers have introduced ParkingScenes, a comprehensive multimodal dataset tailored for end-to-end autonomous parking in simulated environments.
Dataset Overview
ParkingScenes is built on the CARLA simulator and features structured parking trajectories generated through a Hybrid A* planner and Model Predictive Controller (MPC). This innovative approach provides accurate and reproducible supervision signals, which are critical for training robust autonomous parking systems. The dataset comprises:
- 16 Reverse-In Parking Scenarios: These scenarios simulate the common maneuver of reversing a vehicle into a parking space.
- 6 Parallel Parking Scenarios: These scenarios focus on the techniques needed for parallel parking, a skill often required in urban settings.
- Pedestrian Conditions: Each scenario is executed under two conditions: with pedestrians present and absent, adding a layer of complexity to the parking task.
- Structured Episodes: The dataset includes 704 structured episodes, capturing diverse parking situations and challenges.
- Extensive Frame Data: With approximately 105,000 frames, each episode repeats 16 times to ensure thorough coverage and consistency.
Multimodal Fusion and Context-Aware Learning
Each frame in the ParkingScenes dataset contains synchronized data from various sources, including:
- Four RGB cameras, providing high-resolution visual data of the environment.
- Four depth sensors, enabling depth perception and spatial awareness.
- Vehicle motion states, capturing real-time information about the vehicle’s movement and orientation.
- Bird’s-Eye View (BEV) representations, offering a top-down perspective that enhances situational awareness and decision-making.
This rich multimodal data enables researchers to implement context-aware learning techniques, significantly improving the training process for autonomous parking systems.
Performance Comparison and Results
To validate the effectiveness of the ParkingScenes dataset, researchers conducted a comparative analysis between models trained on ParkingScenes and those trained on unstructured, manually collected simulation data under identical conditions. The results demonstrated significant improvements in performance metrics, highlighting the advantages of structured supervision for developing robust parking policies. These findings underscore the dataset’s potential to advance the capabilities of learning-based autonomous parking systems.
Availability and Future Work
By releasing both the ParkingScenes dataset and its collection framework, the research team aims to establish a scalable and reproducible benchmark for future studies in autonomous parking. The dataset and the accompanying framework can be accessed at GitHub – ParkingScenes. This initiative not only addresses existing gaps in the field but also paves the way for further advancements in intelligent driving technologies.
