Laser to drone

[tarrabass]

Hello freak laser people,
for a next summer performance show,
i would like to target dones with laser, try to create constellation in the sky.
i can have the gps of each drone, and the gps of the drone, do you have an idea to how realise that ?
thanks you

... this is best done wit (stereo-) cameras ... I've done something similar for moskitos

- here first testing with stereo-images - https://www.youtube.com/watch?v=NV33f8Ef_Ws

Hello François,

Do you mean that a killer drone with a laser will target another drone, both in flight ?
Thanks.

Halo Viktor,

Very interesting !
Could you give me some details how you can detect, identify and track so fast ?
Thanks,

Hi Fab,

... this was done with the AI-Boards from NVIDIA (smaller Jetson Nano or mainly bigger/faster Jetson Xavier NX), stereo-cameras from Arducam and by me developed software, optimized for high-speed-detecting in the images by analyzing them as numpy-arrays.

AI-based 3D-scanning was slower than my variant -- got up to 30 3D-positions per second, so fast enough to calculate the moskito path and shoot them down with an jetted droplet-array of diluted insecticide.

If I could use lasers, then this would be even faster (no time needed for the droplets to fly through the distance)

Here a video showing the "jet-shooting" - https://www.youtube.com/watch?v=o0ZKSvCb39k

*** EDIT*** - looking through the video - this was done with the first version, where I've used the stereo-cams of a leap motion controller.

The final version was done with the Arducam stereo-cameras (the leap motion cams have heavily "distorted" otptics).

Here I've made a video showing the leap motion in action - https://www.youtube.com/watch?v=1PopB-A-SuU

Halo Viktor,

Thanks for the links and infos !
I was thinking about mounting a coaxial camera with the laser so the detection would send coordinates to galvo to fire ...

Hello,

I guess that drone has been shut down ...
