🎵 what a difference… a Pi cam makes… (first: original Pi cam v2.1, I think they don't make them any longer; second: cheap Joy-IT camera).

some CSI vibes there. Anyone know a Java or Scala image processing library to quickly do the perspective alignment / equalisation of the markers?

@sciss I'm a total newbie to this, why do you need the markers at all? And what mans CSI?

@jayrope I want to be able to undo slight camera movements over time (weeks, months), so I'm taking the four cross-hairs as fixed, and to be used for post processing, in order to be able to crop the same portion of the photo now in four months.

CSI = crime scene investigators

@sciss @jayrope very interesting...please share if you learn more

btw, "traditional" calibration markers always remind me of *these* others markers...I was stunned when I learnt they even exist:
