| # 🛸 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 |

| ### 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` |
