Software

Usage

Collection:

1. Connect all sensors

2. Power on the computer:

   1. If sensors are not connected, data collection fails to start and the computer needs to be restarted

   2. Data collection is automatically run on startup through the /etc/rc.local file

Access:

1. Disconnect all sensors and power on the computer

2. Move or copy the data to be saved

3. Delete the data to free space for future collection

Setup

Code

Open the terminal and navigate to the home directory:

• cd ~/

Follow the instructions: Python Repository

Install packages: pip install imaging/requirements.txt

• Do not use the other requirements files

Startup

The contents of imaging/rc.local.copyme assume the username is warg .

Modifying /etc/rc.local requires superuser access (e.g. sudo ).

Use 1 of the following:

• OpenCV Python:

  • Copy the OpenCV Python section of imaging/rc.local.copyme to /etc/rc.local

• FFmpeg video:

  • Install FFmpeg: sudo apt-get install ffmpeg

  • Copy the FFmpeg video section of imaging/rc.local.copyme to /etc/rc.local

To use the other option, delete the relevant section in /etc/rc.local and redo the steps above.
