A thermal camera for drones is a specialized imaging device that captures infrared radiation (heat) замість видимого світла, enabling the detection of temperature differences in objects and environments. When mounted on a drone, it provides real-time aerial thermal imaging for applications like search and rescue, infrastructure inspections, пожежогасіння, and wildlife monitoring.

Ключові компоненти

1. Термічний датчик
   • Uses a microbolometer to detect infrared radiation (wavelengths: 8–14 мкм).
   • Common resolutions: 160×120 (low-end) до 640×512 (high-end).
   • Діапазон температур: Типово -40°C to +550°C (expandable to +2000°C for industrial use).
2. Об'єктив
   • Made of germanium (transmits IR light) with fixed or adjustable focal lengths (напр., 9мм, 13мм).
   • Wide field of view (FoV) for broad coverage or narrow FoV for detailed inspections.
3. Інтеграція програмного забезпечення
   • Real-time temperature analysis (напр., spot meters, area alerts).
   • Color palettes (залізний лук, grayscale, fusion with visible-light images).
4. Drone Compatibility
   • Designed for popular platforms like DJI Matrice, Autel EVO, or custom FPV drones.
   • Легкий (100–300g) to avoid exceeding drone payload limits.

Top Applications

1. Пошук і порятунок (SAR)
   • Locate missing persons or animals in darkness, туман, or dense foliage.
2. пожежогасіння
   • Identify hotspots in wildfires or structural fires through smoke.
3. Building Inspections
   • Detect heat leaks, electrical faults, or HVAC inefficiencies.
4. Agriculture
   • Monitor crop health, irrigation leaks, or livestock.
5. Wildlife Conservation
   • Track animals at night without disturbing them.
6. Промислові інспекції
   • Survey solar panels, трубопроводи, or power lines for defects.

Integration with Drones

• Монтаж: Attached via gimbal (stabilized) or fixed bracket.
• Live Streaming: Transmits thermal video to a ground control station or goggles.
• Data Logging: Saves radiometric data (temperature metadata) for post-analysis.
• Payload Systems: Some drones pair thermal cameras with RGB cameras, ЛіДАР, or gas sensors.

Buying Considerations

1. Resolution: Вища роздільна здатність (640×512) for detailed inspections.
2. Radiometry: Ensure it captures temperature data (not just images).
3. Drone Compatibility: Check weight, gimbal support, and software integration.
4. програмне забезпечення: Look for AI analytics (напр., automatic hotspot detection).

Example Use Case

A firefighting team deploys a drone with a 640×512 thermal camera to map a wildfire. The camera’s ironbow palette highlights intense heat zones (>300°C), while the live feed helps direct water drops and evacuations. Post-flight, the radiometric data identifies smoldering hotspots needing follow-up.
