guys m new to opencv.. plz help me with my problem.any help would be greatly appreciated. i haven't participate to my opencv sessions well and i cant imagine how to du this. this is my final class assignment..:(

my problem; i want to detect free parking slots in a car park and display wether they are occupied or not.

i have attached the image to be used in identification.i thought to draw red rectangles around each slot when there is no vehicle in the park.(in this case i have to draw 10 rectangles).

when a vehicle occupies any slot from the free slots i thought to change the rectangle color to green.

so plz suggest me any procedure to do this.. if u have any code plz give it to me. thanx. god bless u all. reference image first image description

One approach based on above image,

Threshold your image.
Find contour.
Find rotated rectangle for the contour.
Now fill your rotated rect, will give you mask for all parking area.
Perform bitwise xor between above mask and first threshold image, this will give you mask for each parking slot.
Using this mask you can analyse the background colour for parking slot, can decide whether it is occupied or not.

I do appreciate @Harris giving you a direction on how to solve this, but please do not expect people to completely solve you assignment. This is a Q&A forum which suggest you showing an approach, showing your problems uptil now and then we suggest a new approach or an adaptation of yours. By simply saying you need to pass your final project because you skipped classes, you won't get large support from the community ...
