Parking Spot Locator

Problem Statement Difficulty finding parking spots in public places Takes time to find a parking spot Existing solution Hire people to direct drivers to vacant spots Using security camera and parking attendant Our solution A low cost device to locate the vacant spots in a parking lot Several cameras Personal computer Microcontrollers Image processing software

Solution Process Camera captures images of the parking lot Microcontroller segments images into individual parking spaces by cropping out critical areas of each parking space Microcontroller processes images of the individual parking spaces to determine the status of each parking space. Sends vacant spot ID numbers wirelessly to PC. PC uses information to update a GUI display of the parking lot.

Product Overview Multiple Cameras will be used to cover the entire parking lot Cameras will be installed as shown below. Figure 1: Camera installation Camera must be at least 20 feet high for optimal coverage and accurate results Each camera will cover at least 18 parking spaces 20ft

Results of previous Design group A fairly accurate algorithm for analyzing parking lot images. A MatLAB based GUI display of Parking lot Information (Demo version).

GUI display of Parking Lot

Our Design Options Data Transmission Vacant ID numbers vs. Captured images Burden on PC instead of microcontroller Data Communication Low cost wireless connection Infrared or Radio transmitters Interfacing of the devices Embedded microcontroller into a camera Develop an adaptable microcontroller End User Display A brand new GUI based program

Deliverables A physical product consisting of a laptop, camera, microcontroller, and a parking lot. Camera will capture images over timed intervals Microcontroller will analyze images and send information to laptop wirelessly. Laptop will be able to display the filled and vacant spots.
