$ export LDFLAGS="-L/usr/local/opt/zlib/lib"
$ export CPPFLAGS="-I/usr/local/opt/zlib/include"
$ export LDFLAGS="-L/usr/local/opt/zlib/lib -L/usr/local/opt/sqlite/lib"

Install OpenCV

brew tap homebrew/science
brew install opencv

pip install opencv-python
pip install tornado
pip install opencv-contrib-python

Test OpenCV in Python console

python
>>> import cv2
>>> cv2.__version__
'4.0.0'

Setup

Use an external webcam, so in /track/index.js, we use 1 for the camera id. Use 0 for the internal camera.

this.camera = new cv.VideoCapture(1) // <- for webcam

Also, the default set up is background: black, robots: white. Change the parameter in each file, if you want to change it.

Start

Run server.py in one tab

python server.py

and run websocket dev server in another tab

npm start

Then, you can access to http://localhost:8080/
