14. Is “radiometric video 60Hz” captured in a radiometric format (i.e. with temperature data included like .seq) or in a video format such as.mp4?

Answer:

-> MP4 and mkv only, not in radiometric format yet.

-> Currently, Vio F1 does not support the capability to capture photos or videos in a radiometric format compatible with Flir software. We are collaborating with Flir to implement this functionality soon.

Presently, Vio F1's thermal camera is primarily for direct observation during flight rather than for thermal image analysis applications. We are actively pursuing updates to enhance its capabilities.

Answer:

-> No, it's JPEG, not RJPEG.

16. Do you have an SDK available for post processing captured thermal images? (similar utility to FLIR tools/DJI Thermal SDK)

-> No, we just provide SDK for the payload control and data transmision.

Post processing will be on part of third party software or developer.
