Parking Space Vacancy
Detection




Coming home from work by car, tired


Approach a parking lot close to home to park





And…

Problem…

Home







So, you end up..

Wasting
time

Prone to
accidents

Frustrated

Wasting
gasoline &
diesel fuel




Video Camera & Tripod


MATLAB R2011


Weka


George!

Materials Needed




Any driver


Government


Building owners


Parking Lot owners

Who is my consumer?




Put a camera at a high
vantage point.


Analyze the video to
determine which parking
spots are full and other that
are empty.


Algorithms used

Foreground Estimation




Recorded a 45 minute video of the parking lot
behind
Sama

Tower from the 12
th

floor at
6

o’clock.


Recoded every parking event manually


Ran this and static image processing results through
Weka


Combined Weka results with image processing



What We Did

Taking 24
-
hour video


Precision can be improved by training the algorithm
on the section of the video that has more empty
spaces



Communicating to the user by using a phone app


The phone app will also send direction of the
location of the empty lot.

Future Steps




Camera


Phone App or display


Setup of the system takes a day or so per parking lot

Costs of the Project




We would like to thank George
Chaidos

who offered
great help in writing the algorithms of the
program.


We
also
would thank
Professor
Nikolaos

Mavridis

and Leonard
Retel

Helmrich

for giving us advice on
the project throughout the working process
.
