- Using Balena Etcher, burn the image 2019-04-08-raspbian-stretch-full.zip to micro sd card.
- In the freshly created boot drive, create an empty file named
sshin the boot folder. This is for enabling ssh access by default.- In linux, mount the sd card
sudo mkdir /media/sdcard && sudo mount /dev/sdb1 /media/sdcard
- In linux, mount the sd card
- Create another file called wpa_supplicant.conf. This is for enabling wifi and configuring default wifi connection details.
- Power on Raspberry with the sd card.
- Figure out the IP address of Raspberry.
- From the Wifi Admin console. Or,
- Using network scanning tool like nmap —
nmap -sP 192.168.x.0/24
- SSH to raspi with default credentials, i.e., login: pi and password: raspberry
- Install Dataplicity.
- Change password with command
passwd - Free up space by uninstalling following libraries.
sudo apt-get purge -y wolfram-engine libreoffice* && sudo apt-get clean && sudo apt-get autoremove -y - Expand the file system
sudo raspi-configAdvance Options —> Expand File Systems Reboot
- Update and upgrade
sudo apt-get update -y && sudo apt-get upgrade -y - Install Vim
sudo apt-get install vim - Install PIP
wget https://bootstrap.pypa.io/get-pip.pysudo python3 get-pip.pysudo rm -rf ~/get-pip.py ~/.cache/pip
- Install pre requisites for Open CV3

- Install Virtual Environment
pip install virtualenv=='16.6.1' virtualenvwrapper=='4.8.4' --userecho -e "\n# virtualenv and virtualenvwrapper" >> ~/.profileecho "export WORKON_HOME=$HOME/.virtualenvs" >> ~/.profileecho "export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3" >> ~/.profileecho "source /home/pi/.local/bin/virtualenvwrapper.sh" >> ~/.profile- Add /home/pi/.local/bin/ to $PATH (in ~/.profile)
source ~/.profilemkvirtualenv cv3-py2 -p python2
- Use byobu for running detached ssh sessions. So that, even if dataplicity gets disconnected, your installation process isn't interrupted.
- Activate virtual env and install Numpy
workon cv3-py2pip install numpy=='1.16.4'
- Install OpenCV3 by compiling. Source
