Summary
Resolution | Gain Mode | Use for Sitemark |
Native (640 × 512) | High Gain | ✅ Recommended |
Super-Resolution / UHR | High Gain | ✅ Supported (see limitations below) |
Native (640 × 512) | Low Gain | ❌ Not suitable for solar inspections |
Super-Resolution / UHR | Low Gain | ❌ Not suitable for solar inspections |
Native (640 × 512) | High-Res | ❌ Not supported: no temperature data |
Super-Resolution / UHR | High-Res | ❌ Not supported: no temperature data |
Sensor compatibility:
The Sitemark platform is not compatible with the UHR (sometimes called Super Resolution) photo mode on any of the DJI drones.
If you have a none DJI thermal sensor which is 1280 x 1024 resolution, please contact the Operations Team to discuss suitability.
Super-Resolution (UHR) support
Sitemark supports DJI’s Super-Resolution technology, also called UHR (Ultra High Resolution). Super-Resolution images are processed automatically within your existing workflows, with no additional steps required.
Supported cameras: Matrice 30T (M30T), M4T and M3T. Other cameras can be added on request; contact the Operations Team.
If you have a non-DJI thermal sensor with 1280 × 1024 resolution, please contact the Operations Team to discuss suitability.
What is UHR?
Most DJI thermal sensors have a native resolution of 640 × 512 pixels. Super-Resolution increases the visible image to 1280 × 1024 using software-based enhancement (upscaling and proprietary DJI image processing). The thermal image isn’t captured natively at 1280 × 1024: the temperature data inside the file stays at the native 640 × 512. UHR gives a sharper-looking picture, but no additional temperature detail.
Known limitations with Super-Resolution
Flight Manager view: after processing, Super-Resolution images appear zoomed in. You’ll need to pan the image to see all of it. Let us know if this causes friction.
GSD: the GSD shown for Super-Resolution datasets is incorrect. Divide the displayed value by 2.
Gain Mode
Gain Mode: select High Gain
DJI Pilot 2 offers three infrared gain modes. Only High Gain is suitable for Sitemark solar inspections.
High Gain (−20 to 150 °C): use this. It gives high accuracy across the full temperature range of solar modules, including hotspots.
Low Gain (0 to 550 °C): don’t use for solar. It’s designed for very hot targets such as fires and industrial equipment. Its wide range comes at the cost of accuracy (±5 °C vs ±2 °C), which is too coarse for cell-level anomalies.
High-Res: never use. DJI Pilot 2 states “Temperature measurement not supported” for this mode. The images contain no temperature data, can’t be processed by Sitemark or DJI’s own tools, and will require a reflight.
