AUDREY uses a low-cost, low-resolution vision system to provide guidance in attempting to perform some of the tasks for the AUVSI competition. Implementationof the vision functions is greatly simplified by making use of image analysis functionally included with the CMU camera package.

Color tracking library routines in the camera are used to perform color tracking.

The purpose of the line detection routine is to detect a line and return information about the orientation of the line along with its position in the camera's view. This could be used for an underwater vehicle trying to follow a path. For example, the vehicle could read the information from the camera and rotate along its centerline to orientate itself parallel to the path line. Once it is properly aligned, it can move forward, adjusting its orientation along the way based on updates from the camera.
