Thermal images and temperature data
A long-wave infrared camera images the heat radiated by objects, without any illumination. Resolution is far lower than that of visible cameras, so the field of view and the smallest hot spot that must be resolved decide the detector size and the lens. A radiometric model outputs temperature values; others output an image only.
- Decide whether temperature values are needed. Only a radiometric model delivers them, and the accuracy depends on emissivity and distance.
- Work out the size of one pixel on the object from the field of view and the detector resolution, and compare it with the smallest feature.
- Check the interface, the frame rate, the spectral band and the lens options of the selected model against the host system.
