Hi @Honza_Ferenc!
This is fantastic!! Apologies for the delayed response. SAHI is definitely the best option to detect small drones and maximize detection accuracy at long ranges or the edges. As far as latency, it won’t always be faster when using SAHI compared to one large model due to tiling overhead, but it is far more accurate on small objects in high res images.
I agree, using the original monochrome image stream is your best bet.
Please keep me updated on your progress!!
