# 🛸 STR Drones: FLIR Thermal Calibration Dataset

Welcome to the **FLIR Thermal Calibration Dataset** provided by **STR Drones**. This repository provides a specialized collection of raw, radiometric thermal images captured with FLIR thermography cameras.

This dataset is aimed at software engineers and thermographers needing high-quality benchmarks to validate thermal analysis engines, custom scripts, and post-processing applications that decode FLIR's radiometric JPEG formats.

## 🛠️ Supported Sensors
This dataset covers a range of FLIR hardware, from handheld industrial tools to automation and scientific sensors. Current samples include:

* **Automation & Machine Vision:** FLIR AX8
* **Professional Handheld Series:** FLIR T640
* **Advanced & Point-and-Shoot Series:** FLIR B60, FLIR E40, FLIR Edge Pro
* **Generic FLIR Captures:** Standard FLIR `.jpg` outputs.

| Model | Resolution (W x H) | File Type | Make |
| :--- | :---: | :---: | :--- |
| **FLIR Edge Pro** | 480 x 640 | JPEG | Teledyne FLIR |
| **FLIR T640** | 640 x 480 | JPEG | FLIR Systems AB |
| **FLIR B60** | 180 x 180 | JPEG | FLIR Systems AB |
| **FLIR E40** | 160 x 120 | JPEG | FLIR Systems AB |
| **FLIR AX8** | 80 x 60 | JPEG | FLIR Systems AB |
| **FLIR (Generic)** | 240 x 320 | JPEG | FLIR Systems AB |
| **DJI XT S** | 640 x 512 | JPEG | DJI |
| **DJI XT R** | 640 x 480 | JPEG | DJI |
| **DJI XT2** | 640 x 480 | JPEG | DJI |

## 🚀 Use Cases
* **FLIR Metadata Decoding:** Test your parsers against FLIR's proprietary EXIF structure to accurately extract constants like Planck R1, Planck B, Planck F, Emissivity, and Reflected Apparent Temperature.
* **Temperature Matrix Calculation:** Verify your code's accuracy when calculating the full thermal matrix (pixel-by-pixel temperature) from the raw 16-bit sensor data embedded in the `.jpg`.
* **Cross-Compatibility Validation:** Ensure your software handles different generations of FLIR sensors seamlessly.

> 🔒 **Privacy & Data Protection Note:** All GPS coordinates and sensitive location metadata have been strictly stripped or disabled from the images within this repository. This guarantees the privacy of the surveyed locations while keeping the radiometric and thermographic metadata 100% intact for your calibration needs.

## 📁 Dataset Structure
Files are organized by sensor model (e.g., `FLIR_AX8.jpg`, `FLIR_T640.jpg`). Each file retains its original radiometric integrity, allowing you to treat it exactly as if you had captured it directly from the camera.
