Ready to embark on the exciting journey of autonomous driving? Buckle up as we delve into this intricate world, exploring the vital role of real-world scenarios and the challenges and opportunities they present. From industry standards like ASAM OpenDRIVE and OpenSCENARIO to the complexities of high-fidelity mapping and scenario reconstruction, we'll navigate the heart of this revolution. Join us as we spotlight Matt3r, powering a safer and more efficient autonomous driving future by providing high-quality real-world driving scenarios. This blog post is the first in a two-part series. In this blog, we've laid the foundation for real-world scenarios in autonomous driving, investigating their significance, challenges, and industry innovations. Part 2 will delve deeper into Matt3r's approach to scenario reconstruction. We'll go over the complex processes involved, as well as the general challenges we encountered while working on this project.


Setting the Stage: Understanding Scenarios in Simulation

Scenarios form the foundation of autonomous driving, guiding complex maneuvers and challenging autonomous vehicles to navigate routine traffic and handle critical edge cases. The PEGASUS method recommends using different abstraction levels of scenarios to adequately test the autonomous system across the entire test space. Scenario abstraction levels range from Concrete scenarios, specifying all attributes, to Logical scenarios, allowing user-defined attributes within specified ranges, and Abstract scenarios, providing total freedom with constraints to express dependencies. ASAM OpenDRIVE and OpenSCENARIO are industry-recognized standards that serve as a universal language and aid in the reconstruction of real-world scenarios within the realm of simulation. This is accomplished through the use of simulation-friendly descriptions of road networks, dynamic content, and complex maneuvers. These specifications establish "virtual proving grounds" for developers to test and refine their technology in a controlled environment.


Navigating the Challenges

The journey towards autonomous driving is not without its obstacles. Some of these challenges include accurate mapping for safe navigation, high-fidelity scenarios for enhanced adaptability and edge-case handling, and realistic parameter distributions to ensure robust coverage across both expected and unexpected driving situations. Beyond these technical aspects, covering a diverse spectrum of scenarios is crucial for real-world readiness, while continuous system performance evaluation and regulatory approvals are pivotal for widespread acceptance. Fortunately, the entire industry is working around the clock to contribute innovative solutions that pave the way for a safer and more scalable autonomous driving future. What role do you think individual companies play in advancing autonomous driving technology?


Industry Innovations in Scenario-Based Testing

Across the industry, several noteworthy companies are transforming the scene through innovative approaches to scenario-based testing:

  • Safety Pool Scenario Database, curated from expert knowledge, accident databases, and naturalistic data, holds scenarios at the logical level, contributing to comprehensive scenario coverage without the granularity of concrete details.
  • Using an extensive scenario database derived from publicly available real-world data, d(risk) offers scenarios mapped to specific deployment areas and Operational Design Domains (ODD).
  • DeepScenario integrates commercially available cameras, processing global video streams to provide a unique perspective, capturing the dynamics of the physical world for custom applications.
  • Crafting realistic non-playable characters (NPCs) from real-world drone data, Inverted AI accelerates the development of safe technology for autonomous vehicles through behaviorally diverse simulations.


The Matt3r Approach: Advanced Real-world Scenario Harvesting

At Matt3r, we harvest data from thousands of existing passenger cars as they navigate through diverse real-world scenarios. Our innovative hardware piece, K3Y, serves as the cornerstone of this data collection process, enabling the reconstruction of a wide range of scenarios encountered by vehicles on the road. K3Y employs edge computing to extract key Elem3nts from real-world data, tag interesting scenarios, and upload them to the cloud for further analysis and scenario reconstruction. Our scenario reconstruction and automation pipeline includes several advanced computer vision and data fusion tasks that can handle the diverse data and effectively extract and translate information into simulation-friendly formats. Ultimately, this process generates scenarios enriched with Operational Design Domain (ODD) attributes, resulting in a one-of-a-kind resource for verification and validation (V&V) of Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD). Our scenario database includes concrete scenarios, derived from real-world data with accurate parameter values, ensuring fidelity to real-world conditions. Looking forward, our commitment extends to the evolution of logical scenarios, introducing parameter ranges for enhanced testing capabilities. This visionary approach signifies Matt3r's dedication to advancing the autonomous driving field by bridging the gap between the precision of concrete scenarios and the adaptability of logical scenarios for a dynamic future.
