Background and MotivationBackground and Motivation

►We have all been in a huge parking lot We have all been in a huge parking lot before and not been able to find a before and not been able to find a parking spotparking spot

► Imagine being late for a flight and Imagine being late for a flight and upon entering the huge parking lot, a upon entering the huge parking lot, a simple display tells you exactly how to simple display tells you exactly how to get to a great parking spotget to a great parking spot

►Minimize road rage incidents resulting Minimize road rage incidents resulting from people stealing spotsfrom people stealing spots

Overview of SystemOverview of System

►User will be able to drive up to parking User will be able to drive up to parking lot and view current map of parking lot and view current map of parking spotsspots

►User can then determine the optimal User can then determine the optimal spot and reserve the spot using the spot and reserve the spot using the GUI.GUI.

►The spot will remain reserved until they The spot will remain reserved until they take the spot or their time expires.take the spot or their time expires.

Operation of SystemOperation of System

► Have camera(s) mounted somewhere to view Have camera(s) mounted somewhere to view all of the spotsall of the spots

► Image Processing to determine spot locationsImage Processing to determine spot locations► Snapshot every few secondsSnapshot every few seconds► Have some way of determining spotsHave some way of determining spots
