Parkinglot Monitor

Application Name: Parkinglot Monitor

Author Name: Zhuo Li (Kevin)

Platform: Ubuntu Linux 12.04

Late Updated: March 21st, 2015

This is a simple application of parking lot monitor written in C++ based on OpenCV. It can read from the video file (can be replaced by camera) and decide the time period during which the parking space is occupied or not. The detected motion vehicle and parking space are highlighted in windows during the program running. A log file which record the parking lot information is saved.

A. Running Instruction

The source codes are in src/ directory and the testing video is in res/ directory. You can run the program as following:

1. enter src/ directory.

   $ cd src/
   

2. compile the codes using the written Makefile.

   $ make
   

3. clean up the intermediate object files.(Optional)

   $ make clean
   

4. run the program.

   $ ./parkMonitor parking.avi
   

5. click four points for the detecting parking area, current verison only support a certain clicking sequence.

   Then you can see the car parking video. The blue line segments composed an area which records the parking space you choose. The yellow rectangle highlights the moving car and the green point is the center of the car.

6. you can use your text editro to see the result log file.

   $ <your_editor> ../log/log.txt
   

B. Structure of the Source Codes

There are three .cpp files and three correspongding .h files in src/ directory:

• motionDetector.cpp and motionDetector.h:

  These files contain the class for motion detection including getting the moving objects, deciding whether it is in the parking space, drawing, etc.

• frameHandler.cpp and frameHandler.h:

  These files contain the class for handling the video frame, including image processing like getting grayscale image, extracting foreground and background, etc.

• mouseDetector.cpp and mouseDetector.h:

  These files contain the class for handling mouse clicking during the initialization phase where user should select the area they are interested in.

• monitorLauncher.cpp and monitorLauncher.h:

  These files are the entry of the application which uses the objects of other classes to run the program.
