Dataset Overview

Dataset Name

AU‑AIR Dataset

Description

AU‑AIR is a multimodal UAV aerial dataset containing visual data, object annotations, and flight telemetry (time, GPS, altitude, IMU sensor data, velocity) for UAV vision and robotics applications.

Specification

  • 8 raw RGB videos (total duration > 2 h)
  • 32,283 extracted and annotated frames
  • Bounding‑box labels for eight traffic‑related objects: person, car, van, truck, bicycle, motorcycle, bus, trailer
  • Each frame provides timestamp, GPS, altitude, IMU sensor data, and linear velocity of the UAV

Download

  • Images: link (2.2 GB)
  • Annotations: link (3.9 MB)

Output

The dataset is split into training, validation, and test sets, with a separate file for class names.

Conversion Tool

A TFRecord conversion script is provided with the following arguments:

  • --annotations: path to annotation file (default ./data/annotations.json)
  • --data_dir: directory of image data (default ./data/images/)
  • --output_dir: output directory (default ./data/tfrecords)
  • --splits: list of split percentages (default 80,10)

Dependencies

The dataset relies on common libraries such as numpy and opencv.
