Very cool!

>If you know the flight and the date and time you can easily pinpoint exactly where the plane was and where it was heading. You'd still need reference data from the photo to triangulate where it was taken from. A blurry 600x600 photo is going to have plenty of uncertainty. >Not incredibly challenging at that point to narrow in on roughly where the photos were taken from. Most people probably don't care as long as it…
Those red-green navigation lights are enough. There is only one aircraft position which would satisfy a given relative configuration. PI camera has a known field of view and given hundreds of images one could have directions converging pretty accurately.
Nit pick, it's not using a Pi camera, its using an old Nokia 5.4 phone as a camera.
Also, they're showing (and linking to) FlightRadar24's departure and destination data, it's quite clear they are on one of the approaches to Delhi International (DEL). I don't know how many runways DEL has, but there's no more than 4 possible lines planes take in approach and departure. If i cared enough I could easily work out which of those lines by checking FlightRadar for the history of one of the links, and match the timestamp with the FR tracklog.
Collection 100s of images any attempting to do geometry magic is unnecessarily complicating things. (Which is fine if your goal is to solve complicated problems for fun. But there is a much easier way.)

Haha, I'm working on fixing that. One of my ideas is to run inference again on an image to check if it has any birds. If yes, reject the image.
It's a really cool time to be checking right now! All commercial flights are grounded in Delhi for Republic Day celebrations so I'm able to see images of Air Force planes!

Could you get the speed and location of the plane and estimate how far it should move across two images to determine if its the right target?

That would work if inference on the Pi was faster. Right now it takes about 2.5s per image. The planes are in view for maybe 3s. By the time the next frame is fetched, the plane's already out of view.

#76Watching football this fall, I've been thinking about a little box that sits on my table and mutes the TV whenever an ad comes on. Not decoding HDMI HDCP or anything, but a webcam + AI or whatever that watches football with me and mutes ads. Similar to plane detection, maybe. Are there any projects like this?
Nice idea! Related: In Black Mirror, they pause the advertisement when you disable the sound. So maybe you'll eventually have to use a separate sound system whereby they cannot detect that you're muting it. Then, they'll track your eyes and require you to watch the screen :) At which point do you stop consuming?
"At which point do you stop consuming?"
The tech cultists won't, will always think "urrhurr let's counter this corporate restriction / government regulation with .
It's so rewarding to do simpler things in life instead, f.e. growing your own food and not partake in this "more-and-more pervasive tech spread" BS.

Unfortuntalely that happens more often than I'd like, especially if the frame contains both the plane and a bird. Hoping to fix that in V2!

I'd settle for a device that just normalized the volume levels, but this would be even better!
In the USA since 2010, there have been standards that prohibit ads being louder than the program material:
