Using the Railway Network as a Flatbed Scanner

I have been capturing extremely wide photos by pointing an industrial linear camera out of a moving train window. This process involves stitching together thousands of image lines captured every second. I will discuss the challenges of measuring train speed accurately and collecting data fast enough to create a coherent image, along with the difficulties of processing and displaying such massive files.

I've been taking extremely wide photos by pointing an industrial linear camera out the window of a moving train and stitching together the several thousand lines captured per second after the fact.

    Random thought: If you stick a very small adhesive mirror to the outside window before boarding, then footage "looking down" at the regularly-spaced railroad ties could contribute to information about the current speed and acceleration.

    Well, on a straight section anyway, if you turn, the inner/outer edges will appear differently-spaced...

    Wouldn't do anything positive in terms of suspicious staff though. They might think it's like some kind of heist-movie that will involve a specialized glass cutter making a circle on the window.

    From experience: the iPhone’s panorama photo mode works to take pictures like this from a train.

    Basically the inverse of https://daniel.lawrence.lu/photos/ or https://trains.jo-m.ch/ ;)

    Random thought: if you stick a camera to each train you might know their location better than Deutsche Bahn does.

    I love this so much!

    This is such a cool hack, just for the sake of it. Amazing hacking and amazing art!

    In the preso, she has said the full size output is on the website-

    can anyone see what that link is? I didn't find it on the video page, but I might've just missed it.

More from this day
