Find out who/what the fuck is eating my lunch at night



See title.
Takes picture every time interval (defaults to one picture a second) and make a video of it at the end.
It has a motion detection mode that will detect motion and put a purple rectangle around it (by default it does not do a video at the end but you can call make_video manually if you want to).


pip install -r requirements.txt

Don't forget to install dependencies (jpg lib and ffmpeg or something that works with opencv, libav for Ubuntu) for OpenCV before installing it, otherwise things won't work. On Ubuntu:

$ sudo apt-get install libjpeg-dev libavcodec-dev libavformat-dev libswscale-dev

OpenCV is not pip installable so either install it from your package manager or follow the instructions for your OS at the download page (you can install it in a virtualenv by following this post: Installation of Opencv, numpy, scipy inside a virtualenv).

How to use

$ python rodent.py

There are 4 commands:

  • capture: takes a picture from the webcam at a given interval forever or until the time specified in the folder given
  • make_video: takes all the pictures in the folder and makes a video out of it (better than watching pictures!)
  • automate: does both capture and make_video, I use it for example to record until 15 minutes before I wake up and the video will be ready by the time I get to the kitchen for example
  • motion: takes a picture only if it detects a movement
