Camunits consists of an image acquisition library, algorithms, and tools designed specifically for machine vision researchers. It was originally designed and used by Team MIT for real-time vision-based lane estimation in the 2007 DARPA Urban Challenge, and is now being developed and released as an open source project.

Camunits is written in C and uses GLib.

Features

Camunits is divided into several pieces.

libcamunits	Provides the core functionality of Camunits, which includes classes for acquiring images from USB and Firewire cameras, logging and replaying image streams, performing colorspace conversions and image compression/decompression, and connecting image processing elements together
libcamunits-gtk	Provides GTK widgets for libcamunit objects for easily adding GUI elements.
camview	Debugging tool and general purpose Camunits application
camunits extra	Provides image processing and acquisition plugins that may contain nonstandard dependencies, or algorithms for special interest purposes.

Requirements

Camunits currently works on the GNU/Linux and OS X operating systems. libcamunits has a few main dependencies

GLib
OpenGL
libjpeg

IEEE 1394 Digital Camera support is provided as a plugin, and requires libdc1394 version 2.x:
