On telescope camera for plane spotting
« on: September 02, 2016, 12:13:36 PM »
Who uses an optical camera system to detect aircraft around the laser pointing direction? We are interested in perhaps trialling such a system at Herstmonceux.  Are the aircraft always identifiable in the images? What method do you use for detection? Can it work at night?

Cheers

Matt

We are using Mintron CCTV attached to telescope,  approx 2x4 deg FOV, plane navigation lights are visible in night.

Hi Kalvis

That's quite a narrow FOV.  We are wondering here @Hx what would be the best approach, either to use a wider image to spot approaching planes and take action when necessary or to have a narrower field to immediately shutoff when any plane like object appears in the frame (perhaps using a comparison to an earlier frame).

We've not tested our camera at night yet.

In our experience FOV is  sufficient  to have  a time to manually use safety switch to block outgoing laser beam. From the other hand - plane entering FOV of camera is a quite rare event for our system and location.

Hi

I am making good progress on our plane detection camera.  I presented the technique in a poster at the 2018 ILRS Workshop https://cddis.nasa.gov/lw21/images/poster.jpg.

I've made some effort to not detect clouds, but i am triggering on birds and insects.  I will have to see if this becomes a problem.

I'm using a visible spectrum, monochrome camera at the moment.  It has too many pixels and so will only run at 5-7Hz. I plan to test a faster colour camera.

Who is working on optical aircraft detection? Do you expect to build a reliable system??

Good morning.
We are currently defining our Telescope system (our plan is to buy it this year). It is really interesting your work related with the optical camera for aircraft security. So we will have it into consideration for our system (in addition with ads-b, flarm, all-sky camera, directional microphone...).
Best regards.

Great you're getting the telescope Serna, good luck with it.

We'll have to start a new topic discussion on directional microphones soon.  We are just thinking about trying some experiments.
