ha! yea.... The camera itself doesn't know when a building gets in the way. I have some general stop angles, but it is not perfect. There is some ML in there to get rid of photos like this... but I guess the model things that air condi

In theory it should work with any camera the supports ONVIF, which is a standard for security cameras... actually, as long as the camera has an API you could probably get it to work. Since precision and image quality are important though, i

That is interesting! There is this cool piece of software that looked like it helped with a lot of this. It did visual object tracking with telescopes... but it is no longer available: http://www.optictracker.com/What_is_it.

I am not sure if it is actually useful... but if folks have ideas, I would love to hear them! I worked on it mostly to see if it could be done.

Totally - I think you could work back where the camera is based. I have the bearing / azimuth of the camera for each photo, so you could look up where each plane was at that timestamp and then project backwards. I bet you had much bet

It should work for helicopters. In DC, alot of them do not have ADS-B and the flight paths are a little different, so I haven't managed to capture one yet though.

That would be awesome! How fast can those mounts move? Would they be able to follow an aircraft? I have found that more zoom actually makes things a little tricker because you have to make sure it is leveled and aligned precisely. When my c

Thats amazing! If I lived anywhere near the water I would want to try and set something like this up.

I posted a bit more on what I am using on the About page: http://skybot.cam/about I got all the camera gear on ebay, which was lucky. I figure since it is all based on ADS-B data, there isn't anything too crazy about m

I managed to get it for $500 on ebay... but I just checked and it looks like similar ones are around $1000 now, so I guess I got lucky. An Axis PTZ dome camera turned upside down works great too though and there are a lot of those available

I just upgraded the App Service plan I was using... It should be back now for a bit.

You could get away with a pretty cheap hosting bill, I think a $10 VPC would be more than enough. My current Azure forecast is around $65, but that is for a couple other things too. Half the reason I went big with the different features is

Definitely - Let me build a little better dataset. I need to augment a bit because it was false detecting on some of the contrails. I built some scripts to also start building a model that can classify the different aircraft models. One of

Good question - I just checked and my forecast for the month is $65... but I have a few other things running. One of the perks of working at Microsoft is that you get $150 monthly credit, so I didn't work too hard to keep the costs low

Oh! that is a great idea. I am already tracking the camera's azimuth and elevation so I could probably composite everything to togther.

I have been using this Docker image on my Pi and it has been rock solid once you get it setup: https://github.com/mikenye/docker-piaware

oh yea! great point, I forgot about that. I am using PiAware to handle the decoding so I do have an Enterprise Account. I will have to check if I can make API calls for free.

Let me know if you ever go down this rabbit-hole. Happy to give you pointers! You can get some pretty decent cameras off ebay for <$500. Since you are close you do not need much zoom.

Doing a vision only approach would be really cool. A lot of the interesting planes do not have their ADS-B transponder on. The two systems could actually work well together. My system ends up generating a really nice, labeled dataset. I put

Hi! I am the guy behind this, awesome to see it posted here. Happy to answer any questions. To answer a question I saw pop up, I am using the FAA aircraft registration data to pull up the extra information about the planes. It lists who act

This sounds awesome - If you have any documentation up on how to do this, I would love to point to it from the trunk-recorder wiki.
