I love line scan cameras. Wikipedia has an awesome photo of a tram taken with a line scan camera on the relevant wiki page[1].
I've just moved to a house with a train line track out front. I want to see if I can use a normal camera to emulate a line scan camera. I have tried with a few random YouTube videos I found [2].
I think the biggest issue I face is that there simply isn't the frame rate in most camera's to get a nicely detailed line scan effect.

- mkl 1y agoA normal frame rate is probably enough if you do it with groups of columns rather than a single column of pixels. That's what https://trains.jo-m.ch/ https://trains.jo-m.ch/ does with a Raspberry Pi camera, posted in https://news.ycombinator.com/item?id=35738987 https://news.ycombinator.com/item?id=35738987 with lots of questions and answers.
- hifikuno 1y agoOh wow that's neat! I honestly didn't think of using chunks instead of a single line and the result looks pretty good. I love the fact the top (or first?) comment is by dllu, and looking on their webpage I saw the tram photo from Wikipedia! It's cool to see the photographer talking about their work. I think about that tram photo so much.
