Autom

A data recording and video capturing module written in Python for a Chevy Volt.

Requirements

• Python 2.7
• OpenCV (Python and C++)
• pysftp
• pyvit
• ConfigParser
• moviepy

Hardware

• CANtact OR CANable
• Raspberry Pi or other small computer/mini PC running Linux (if you use a Pi, you may want to also get a UPS for it as well for data backup operations after the car is turned off)
• Any secondary PC at home that is always on (preferably running some Linux distribution, but not necessary)
• A reasonably priced good to high quality webcamera. Personal recommendation: Microsoft LifeCam HD-3000

How To Use Recording

1. Setup an SSH server on a home computer that will always be on.

sudo apt-get install openssh-server

(Optional) For those who would like to use public/private key authentication to use SFTP

• Create a public/private key pair on the car PC to use to login to your SSH server instead of using a password

ssh-keygen -b 4096

• Transfer the public key to the remote home computer

ssh-copy-id username@hostIP

2. Create backup folder in home directory on the remote computer.

mkdir ~/backup/

3. Specify the server IP, username, password, port number (default is 22 for SSH), and make sure ifPassword = True and set sshPass in config.cfg.

(Optional) For those using a private key

• Specify the server IP, username, private key location, port number, and make sure ifPassword = False in config.cfg.

4. On PC for car installation, clone a copy of Autom anywhere.
5. Add gnome-terminal -e "path/to/Autom/run.sh" to startup applications on the car PC. If you are using Ubuntu, you can do this by cd'ing to the root directory of this project and executing the following command:

echo -e "[Desktop Entry]\nType=Application\nName=Autom\nExec=gnome-terminal -e \"`pwd`/record/run.sh\"\nIcon=\nComment=\nX-GNOME-Autostart-enabled=true" >> ~/.config/autostart/Autom.desktop

6. Make sure car PC has the home network as a known network.
7. Plug in CANtact/CANable into vehicle OBD-II port and then into car PC usb port.
8. Attach webcamera to front of rearview mirror to get a view of the road, then plug into car PC.
9. Attach car PC to vehicle power source.
10. Power on the PC and the car and start driving.
