Watching 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 some point pirates come along with their own streams offering better service :P

MBAs think they can enshittfy into perpetuity, but eventually people have enough and leave to whatever the competition is.

Black mirror haha I think Samsung actually does it.

I recommend to not show dates as it can easily help triangulate your location of where this Pi is running, and with the internet crowd, doxxing yourself is never a good idea.

How much accuracy can you possibly get from a 600x600 image?

Maybe if the sky is cut away around the plane, I guess you could still make out a shadow on the tube/from the wings/engine nacelle

This is great. So I’ve thought of doing something slightly similar but with a raspberry Pi and camera to identify if there is a free parking space right outside our house (we live in a terraced house with no driveway)

I think this has been done for public places. A lazy approach (not using ML) is cropping/contour finding, then masking (opencv) against an empty parking lot, so if something is there like a car, would change the result.

The black parking lot would change in shade/hue so have to account for a range.

You can see from the photos how people might mistake planes for drones or UAP's.

Every single one of those pictures, even the blurry ones, even the ones taken at night, all look like airplanes. People aren't getting airplanes confused with drones because they look the same. People are getting worked up about drones because of collective paranoia, and then they are seeing what they want to see.

I don't even know what they're afraid of, these drones aren't carrying an RPG round like in Ukraine. I guess it's not impossible.

Depends on how far from the airport you are, and the accuracy of the timestamp. If you have accurate-to-the-second timestamps and you're within maybe 10km of the airport I think you could get down to a neighborhood pretty easily.

You know roughly the perspective that the camera sees the plane from, so you take the plane position at that timestamp and project that perspective line down onto the ground. The higher the plane, the more error there is with estimating the observation axis, so the less accurate this gets.

i'm about to do it myself. the streaming services are just generally putting out shitty content (there's the occasional gem), charging more, and creating more and more walled gardens. it sucks to be a consumer right now other than the "ease" in which you can access these services.

If you know the flight and the date and time you can easily pinpoint exactly where the plane was and where it was heading. Not incredibly challenging at that point to narrow in on roughly where the photos were taken from.

>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.

Probably don't even need the webcam, detection via audio seems possible.
