# HIT-UAV: A high-altitude infrared thermal dataset for Unmanned Aerial Vehicle-based object detection
## Introduction
The HIT-UAV contains 2898 infrared thermal images extracted from 43470 frames, captured by UAV from different scenes (schools, parking lots, roads, playgrounds, etc.), covering a wide range of aspects including objects (Person, Bicycle, Car, OtherVehicle), flight altitude data (from 60 to 130 meters), camera perspective data (from 30 to 90 degrees), and daylight intensity (day and night).

## Annotation
The HIT-UAV provide two bounding box type, oriented and standard.
The oriented annotation can decrease the overlap of bounding boxes to improve the performance of detection algorithms.  

- Standard bounding box record format: $[xc, yc, w, h]$.
- Oriented bounding box record format: $[xc, yc, w, h, \theta]$, where $\theta$ denotes the oriented angle from the horizontal direction of the standard bounding box.

For each annotation method, we provide the XML and JSON label file to help user utilize the HIT-UAV:

- *normal_xml* folder: record standard bounding boxes using xml file.
- *normal_json* folder: record standard bounding boxes using json file.
- *rotate_xml* folder: record oriented bounding boxes using xml file.
- *rotate_json* folder: record oriented bounding boxes using json file.

## Sample images
