pylapse's Introduction

PyLaspe - A simple Python tool based on OpenCV to generate time-lapses

Pre-requisites

  • python3
  • opencv
  • tqdm

For long time-lapses, it may be useful to set it up on a Raspberry Pi

apt-get update
apt install python3-opencv

Launch the picture-taking process

The following command

python3 -m pylaspe --itype=sec --dtype=day --night=10 --output=mylapse \
    --webcam=0 3 10

Will take pictures with webcam 0 for 3 days every 10 seconds (every 100 seconds during the night) and store the pictures in folder mylapse

The time types (--dtype, --itype) can be:

  • sec
  • min
  • hour
  • day

Make the movie

python3 -m pylaspe.make --fps=24 mylapse mylapse.mp4

Will make the video mylapse.mp4 from folder mylapse.

It will automatically handle partially grey images (capture issues) and remove black pictures. You may use the --start and --end options to make a smaller clip.
