Drivable Area Segmentation Dataset

Project Overview:

Objective

We embarked on a mission to meticulously compile a dataset that excels in drivable area segmentation. This dataset is not just a collection of images; it’s a testament to our commitment to enhancing the precision and safety of autonomous driving systems.

Scope

Gathering images from various road conditions, terrains, and urban settings. Annotating these images to delineate drivable surfaces from non-drivable areas.

Sources

Bustling urban streets from major global cities.
Suburban roads reflecting diverse neighborhood characteristics.
Serene rural paths from agricultural landscapes.
Expansive highways and fast-moving motorways.
Challenging off-road trails for specialized vehicles.
A spectrum of weather scenarios, from sunny to snowy.

Data Collection Metrics

Total Data Points: 450,000 images
Urban Streets: 150,000
Suburban Roads: 100,000
Rural Roads: 50,000
Highways/Motorways: 125,000
Off-road Trails: 25,000

Annotation Process

Stages

1. Raw Data Cleaning: We meticulously sift through the data, ensuring clarity and relevance.
2. Basic Road Segmentation: Our first layer of annotation highlights the primary drivable surfaces.
3. Detailed Segmentation: We delve deeper, marking out lanes, shoulders, parking zones, pedestrian areas, and more.
4. Obstacle Annotation: Identifying potential road hazards is crucial for safety.
5. Annotation Review: A final sweep guarantees consistency and accuracy across the dataset.

Annotation Metrics

- Total Annotations: 1,800,000 (4 segments per image on average)
- Basic Road Segmentation: 450,000
- Detailed Segmentation: 1,125,000
- Obstacle Annotations: 225,000
- Annotations Reviewed: 180,000

Quality Assurance

Expert Review: Select annotations undergo scrutiny by autonomous driving specialists.
Automated Checks: Advanced algorithms aid in spotting inconsistencies.
Inter-annotator Agreement: Multiple annotators provide a unified vision for each image.

QA Metrics

Annotations Reviewed by Experts: 180,000 (10% of total annotations)
Inconsistencies Identified and Rectified: 18,000 (1% of total annotations)

Conclusion

The Drivable Area Segmentation Dataset serves as a cornerstone for the development of reliable and safe autonomous driving systems. Through its extensive coverage of diverse road conditions and meticulous annotations, the dataset ensures that AI systems can accurately recognize and navigate drivable terrains in real-world settings.
