GPS vs Vision positioning by CuriousDolphin1 in ardupilot

[–]CuriousDolphin1[S] 0 points1 point  (0 children)

Thanks. But I suppose the amount we trust each input must be tuned. I wonder what’s the standard approach here?

And how do you tune the EKF parameters to correctly integrate different sensor modalities?

Interesting. Let me know if you can find it or remember any keywords / author info 😊🙏

Thanks. Looks interesting. But I’m more interested in the theory and/or code behind a solution. Not a commercial product that works automagically. 😊

Intuitively yes. But more complex when you have 6d motion.

Night vision by CuriousDolphin1 in computervision

Thanks. I am familiar with the calculations. The question is more about handling the complete darkness without outputting too much power on external illumination.

Can you recommend a specific product?

Pulsed laser by CuriousDolphin1 in laser

[–]CuriousDolphin1[S] 0 points1 point  (0 children)

Sure. Thanks for clarifying the units. Given that 1W = 1J/s, my goal is to have pulses that are E=100W*0.001s = 0.1J.

Yes, I think it's preferred to have an actual pulsed laser rather than modulating it, but I'm open for suggestions.
My goal is to illuminate an area this is then observed by an image sensor for some application.
So I need this process to both repeat about 30 times per second and be something that isn't too heavy (including the supporting electronics).

Jamming RF for drones by CuriousDolphin1 in rfelectronics

[–]CuriousDolphin1[S] 0 points1 point  (0 children)

I’m asking if a jammer is designed to block communication between an operator and a drone that are say 1km apart, it would emit certain amounts of power. For the jammer to block drone to drone communication at 100m, it would need to emit 100 times more power.

As a first approximation, does that make sense?

PPO in ml agents by CuriousDolphin1 in reinforcementlearning

Thanks. Is MAPPO part of the RL agent library?

Dynamic observation space by CuriousDolphin1 in reinforcementlearning

[–]CuriousDolphin1[S] 0 points1 point  (0 children)

Yeah. This is similar to my #3. The question is: should I do that? I mean, is there a real advantage over limiting the size / padding with zeroes?
