Re: [LUG] PI and time lapse photography

 

Hi.

I've done this, not with a pi but a few years ago with an axis ip
camera and a debian server. The subject was a new large log cabin
office building for work, and at the end of the build I showed the
timelapse video to the Estonian builders who were enthralled by it.
(And I gave them a copy to take home)

I don't think it matters what sort of camera, provided you can grab a
jpg off it at fixed intervals and save them as sequentially named
jpgs. (1.jpg 2.jpg 3.jpg etc)

To make the actual file, I used ffmpeg to combine all the jpgs
together into a video. Lots of examples out there, and a bit of trial
and error and you've got your picture.

Mine was over a period of some 3 months. I manually removed the
night-time pics, although with more foresight my cron script would
have turned off at night, and I skipped a few frames to get the right
tempo.

Changing the angle requires stepper-motor driven tracks and rails. In
my example, the subject required a static shot. Not sure why you'd
change the rates, but I'm no artist - I imagine you could do this when
compiling the video or at time of shot.

I see no reason why that wouldn't work on a pi, even compiling the
video didn't take long on a normal pc, provided you have enough disk
space.
