H30T field of view: width covered on the ground by the visible and thermal camera
Would you like to know the field of view of the Zenmuse H30T and how wide it covers on the ground at different altitudes? This article gives you the precise answers for the visible camera and the thermal camera, with the help of clear tables and rigorous calculations.
Knowing this data is essential for:
- Optimize flight paths
- Limit unnecessary overlap
- Gain autonomy and efficiency
Here is a precise and illustrated deciphering of the real ground coverage values for two major sensors of the Zenmuse H30T :
- Wide-angle camera (visible, 48 MP)
- Thermal imaging camera (640×512 or 1280×1024 resolution)
H30T Field of View – Wide-Angle Camera
Technical characteristics
- 1/1.3″ sensor, 48 MP
- Equivalent focal length: 24mm full-frame
- Horizontal Field of View (HFOV): Approx. 69.6°
Calculation formula
Ground Covered Width≈1.39×flight altitude (m)\text{Ground Covered Width} ≈ 1.39 × \text{Flight Altitude (m)}Ground Covered Width≈1.39×Flight Altitude (m)
Coverage Chart – Visible Camera
| Flight altitude (m) | Covered width (m) |
|---|---|
| 20 m | 27.8 m |
| 30 m | 41.7 m |
| 40 m | 55.6 m |
| 50 m | 69.5 m |
| 60 m | 83.4 m |
| 80 m | 111.2 m |
| 100 m | 139.0 m |
Recommendation : Provide a 5-10% lateral overlap to ensure continuous coverage without loss of information.
H30T Field of View – Thermal Imaging Camera
Technical characteristics
- Actual focal length: 24 mm
- Resolution: 640×512 or 1280×1024
- Horizontal Field of View (HFOV): Approx. 36.3°
The field of view remains the same regardless of the resolution (the level of detail changes, not the angle of view).
Calculation formula
Ground Covered Width≈0.655×Flight Altitude (m)\text{Ground Covered Width} ≈ 0.655 × \text{Flight Altitude (m)}Ground Covered Width≈0.655×Flight Altitude (m)
Coverage Chart – Thermal Camera
| Flight altitude (m) | Covered width (m) |
|---|---|
| 20 m | 13.1 m |
| 30 m | 19.7 m |
| 40 m | 26.2 m |
| 50 m | 32.8 m |
| 60 m | 39.3 m |
| 80 m | 52.4 m |
| 100 m | 65.5 m |
At 50 m high, the thermal image covers about 32.8 meters in width.
In short: which camera for which mission?
| Camera Type | Width covered at 50 m | Recommended Use |
|---|---|---|
| Wide-angle (visible) | ~69.5 m | Visual surveillance, wide inspection |
| Thermal (IR) | ~32.8 m | Heat research, safety, maintenance |
Conclusion
Mastering the H30T field of vision means mastering your mission. Whether you’re using the visible camera to cover large areas, or the thermal camera to detect hot spots accurately, this information allows you to:
- Define optimal path spacing
- Reduce flight times
- Get actionable data without cropping
