2. Background and Motivation We have all been in a huge parking lot before and not been able to find a parking spot We have all been in a huge parking lot before and not been able to find a parking spot Imagine being late for a flight and upon entering the huge parking lot, a simple display tells you exactly how to get to a great parking spot Imagine being late for a flight and upon entering the huge parking lot, a simple display tells you exactly how to get to a great parking spot Minimize road rage incidents resulting from people stealing spots Minimize road rage incidents resulting from people stealing spots

3. Overview of System User will be able to drive up to parking lot and view current map of parking spots User will be able to drive up to parking lot and view current map of parking spots User can then determine the optimal spot and reserve the spot using the GUI. User can then determine the optimal spot and reserve the spot using the GUI. The spot will remain reserved until they take the spot or their time expires. The spot will remain reserved until they take the spot or their time expires.

4. Operation of System Have camera(s) mounted somewhere to view all of the spots Have camera(s) mounted somewhere to view all of the spots Image Processing to determine spot locations Image Processing to determine spot locations Snapshot every few seconds Snapshot every few seconds Have some way of determining spots Have some way of determining spots -Have reference image to compare current image to -Have reference image to compare current image to -Compare image I to image I-1, look for noticeable differences -Compare image I to image I-1, look for noticeable differences Subtle differences (between spans of seconds) can be caused by ambient conditions, shadows, etc Subtle differences (between spans of seconds) can be caused by ambient conditions, shadows, etc

5. Parts Video Camera Video Camera Webcam, wireless Webcam, wireless Interaction with user Interaction with user Output: Display – to show user available spots Output: Display – to show user available spots Input: Keypad, some way for user to choose spot Input: Keypad, some way for user to choose spot

6. Things to Consider How many cameras? How many cameras? More cameras will yield a greater accuracy on which spots are open and which are not More cameras will yield a greater accuracy on which spots are open and which are not Unknown factors may block a camera such as a large truck blocking one camera entirely Unknown factors may block a camera such as a large truck blocking one camera entirely Angle of cameras to cars Angle of cameras to cars facing parallel or perpendicular to suns path facing parallel or perpendicular to suns path Glare of sun will be a factor Glare of sun will be a factor Should be positioned parallel to the cars Should be positioned parallel to the cars Image Processing Image Processing When should the comparative snapshot be updated? When should the comparative snapshot be updated?

8. Image Processing Logitech web cameras have API available Logitech web cameras have API available Possibly develop our own image processing tool Possibly develop our own image processing tool Import frame from camera, import into MATLAB or similar tool for processing Import frame from camera, import into MATLAB or similar tool for processing Take comparative snapshot array and subtract it from base snapshot array to see differences Take comparative snapshot array and subtract it from base snapshot array to see differences

9. Testing Our System Get the camera(s) mounted within the month Get the camera(s) mounted within the month Start capturing pictures and getting the picture array data into a usable form.

13. Deliverables Camera mounted above a parking lot Camera mounted above a parking lot Image gets sent to base station, which is able to accurately map out the parking spots Image gets sent to base station, which is able to accurately map out the parking spots Have user drive up to parking lot and select a vacant spot Have user drive up to parking lot and select a vacant spot System reserves spot for user, updates map when user parked System reserves spot for user, updates map when user parked
