Runtime Dependencies

All the code was developed and tested in Linux. Most tools are cross-platform and the rest should be easily portable to other platforms.

The following packages are required to run the programs in Linux:

• v4l-utils
• gstreamer-1.0
• jq
• inotify (for spec3, and multicam)
• geographiclib (only for scripts in 'utilities' folder)
• exiftool (only for scripts in 'utilities' folder)
• opencv >= v2.4 (for programs in 'focus' folder)
• ImageJ (for programs in 'alignment' folder)

On a Debian / Ubuntu system, the following command line instructions can be used to install all required packages:

# v4l-utils
sudo apt-get install v4l-utils 

# gstreamer-1.0
sudo apt-get install gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly

# jq
sudo apt-get install jq

# inotify
sudo apt-get install inotify-tools

# geographiclib
sudo apt-get install geographiclib-tools

# exiftool
sudo apt-get install libimage-exiftool-perl

# opencv
check README inside ./focus

# ImageJ
check README inside ./alignment

Repository Structure

The structure of the repository is as follows:

• alignment: contains the code for image alignment.
• arduino: contains the code for the MCU in the USB Camera HUB board.
• camera: contains the code to interface with individual cameras.
• focus: contains the code for camera focus operations.
• matlab: contains matlab code for processing images.
• multicam: contains the code to interface with multiple cameras.
• spec3: contains the code to interface with the 3-cameras multispectral system.
• spec3_rijesh: contains a variation of spec3 used by Rijesh.
• tests: contains testing code under development.
• utilities: contains a series of utility scripts.

Running Code

This repository contains code written in multiple languages (Shell Scripts, C++, Java, Matlab). Most programs include instructions inside on how to execute and what arguments are needed. In some cases, information is also provided in the README files of each folder.
