Bosch Traffic Light Images with State Annotations

A collection of 13,427 camera images with approximately 24,000 annotated traffic lights. The annotations include bounding boxes and the active light state for each traffic light. Images are provided as raw 12-bit HDR and reconstructed 8-bit RGB formats.

Use Cases

• Train an object detection model to locate traffic lights using the provided bounding box annotations.
• Classify the active state of traffic lights (e.g., red, yellow, green) using the state labels associated with each annotation.
• Compare model performance between raw 12-bit HDR images and the provided 8-bit RGB images for traffic light recognition tasks.
• Analyze potential artifacts or color distribution issues in the reconstructed RGB images as noted in the dataset description.

Strengths

• Contains 13,427 high-resolution images at 1280x720 pixels.
• Includes approximately 24,000 annotated traffic light instances.
• Provides both raw 12-bit HDR images and reconstructed 8-bit RGB images for comparison.

Limitations

• The RGB conversion process may introduce artifacts and unusual color distributions, as noted in the description.
• The dataset's geographic and temporal coverage is not specified, limiting generalizability assessments.
