Opencv people counter

[bandann]

Hello.


I have to count the incoming people for a shop, i need to know how many people go through the entrance.
I'm trying to do that with opencv and python, but i can't find any good tutorial for that.


Any help would be highly appreciated

Any idea?

I think this might be very complicated ... is using two light barriers not an option ?

Thank you for your answer.

I wish to use a more accurate solution and even a small camera on the ceiling is a nicer solution too.

You could do something like:
- take pictures every few seconds.
- reduce number of pixels
- convert to greyscale with standardised mean and variance
- get difference of consecutive pictures
- feed into numpy array
meanwhile record (from the pictures probably) the number of people coming into and out of the shop.
Then simply feed your data through a version of google's AI system http://www.nature.com/nature/journal/v5 ... 14236.html or try just using some simpler correlation function. Probably not terribly accurate but might be fun.

Alternatively you could try running a face recognition algorithm on each picture and use that data instead https://realpython.com/blog/python/face ... th-python/
