🛸 STR Drones: DJI Thermal Calibration Dataset

Welcome to the DJI Thermal Calibration Dataset provided by STR Drones. This repository contains a curated collection of raw, radiometric thermal images captured exclusively with DJI Enterprise sensors.

It is designed for developers, researchers, and remote sensing professionals who need to build, test, and calibrate post-processing software that reads DJI's proprietary radiometric metadata.

🛠️ Supported Sensors

This dataset includes sample telemetry and radiometric .JPG / .RJPG imagery from the following DJI platforms and payloads:

Matrice & Zenmuse Series: Zenmuse H30T, Zenmuse H20T, Zenmuse H20N, Matrice 30T (M30T)
Mavic Series: Mavic 4 Thermal (M4T), Mavic 3 Thermal (M3T), Mavic 2 Enterprise Advanced (M2EA)
Dock Series: Matrice 3TD (M3TD)
Legacy/Collaborative Sensors: Zenmuse XT2, Zenmuse XT S, Zenmuse XT R

🖼️ Examples

DJI H30T	DJI M4T	DJI M30T

DJI M3TD	DJI H20N	DJI H20T

DJI XTS	DJI M2EA	DJI M3T

Technical Notes:

Modifiable Parameters: The standard 4 parameters are:
- Object Distance
- Emissivity
- Relative Humidity
- Reflected Temperature
Newer models (H30T/M4T) support a 5th parameter:
- Ambient Temperature
- Old DJI models contain this parameter with a default value of 25ºC.
EXIF Compatibility: Models marked with ❌ store thermal data in encrypted proprietary structures; these require specific decryption/mapping via DJI's native libraries.
Metadata Versioning: All dataset metadata and telemetry extraction was performed using ExifTool version 13.59.

🔒 Privacy & Data Protection Note: All GPS coordinates, altitude data, and location-specific metadata have been intentionally stripped or disabled. This ensures geographic anonymity without affecting the core radiometric telemetry.

📁 Dataset Structure

The dataset is organized by camera model. Inside each folder, you will find raw images and corresponding metadata files:

EXIF metadata: Provided as .json
DJI Thermal SDK metadata: Provided as .json
