Draw This is a polaroid camera that draws cartoons. You point, and shoot - and out pops a cartoon; the camera's best interpretation of what it saw. The camera is a mash up of a neural network for object recognition, the google quickdraw dataset, a thermal printer, and a raspberry pi.
The software can run both on a desktop environment such as a laptop, or an embedded environment on a raspberry pi.
- Requirements:
- Python 2.7
- install dependencies using
pip install -r requirements.txt
from thecartoonify
subdirectory. - install app using
pip install -e .
from within thecartoonify
directory - run app from command line using
cartoonify
- you will be asked if you want to download the cartoon dataset and tensorflow model. Select yes.
- close the app using cntrl-C once the downloads have finished.
- start the app again using
cartoonify --gui
The following wiring diagram will get you started with a shutter button and a status LED. If the software is working correctly, the status LED should light up for 2-3 seconds when the shutter is pressed while the raspi is processing an image. If the light stays on, something has gone wrong (most likely the camera is unplugged).

requirements:
- raspberry pi 3
- rasbian stretch image on 16gb SD card (8gb too small)
- internet access on the raspi
- pip + python
- raspi camera v2
- a button, led, 220 ohm resistor and breadboard
- (optional) Thermal printer to suit a raspi 3
-
install docker on the raspi by running:
curl -sSL https://get.docker.com | sh
-
set up and enable the raspi camera through
raspi-config
-
clone the source code from this repo
-
run
./raspi-build.sh
. This will download the google quickdraw dataset and tensorflow model, then build the required docker image. -
run
./raspi-run.sh
. This will start the docker image.
- Check the log files in the
cartoonify/logs
folder for any error messages. - The most common issue when running on a raspi is not having the camera plugged in correctly.
- If nothing is printing, check the logs then check whether images are being saved to
cartoonify/images
. - Check that you can manually print something from the thermal printer from the command line.
