sbiewald3542252dTracking the amount of devices (e.g. WiFi / Bluetooth mac address). Be aware this probably not privacy friendly and might be illegal as individuals could be tracked, too.
Of course this only helps you if you want to establish it or is already present.
PrivateGER18033252dYeah, the best way would probably be to collect the count of devices sending out WiFi probes. Normalize the data and you got a pretty accurate value.
I don't know how privacy friendly that is. You'd probably need to put a disclaimer somewhere.
electrineer14210252dYour local police force may have a way. At least if you're in China.
Predicting human behaviour is either futile or trivial.
If you are looking into real time estimations (not predictions) and if you are considering larger „places”, you need to contact mobile network providers.
ksuchak19906252dThis is very close to my PhD research topic. What I would say is that if you choose to go down the route of either WiFi, cell or social media data then this is simply a proxy for your density, and a biased one at that - these figures tend to provide coverage of younger demographics but often don't cover the elderly.
Beyond this, these data sources may not provide you with a complete map of the density, and only give you data for certain geolocations - do you want to infer information about the points in-between?
kescherRant26603252dThe game "Ingress" does this to calculate the amount of energy you can collect in different areas. Backed by Google location data, of course.
Wisecrack3788252dTheres a simpler way of doing this.
Get the average color of the location when the least number of people are present, preferably when no one is present. Basically you're taking a picture of the static background.
Get the average that it deviates from for a single person.
Now, when you want to determine density, grab a frame, and look at all the pixels, and determine how far each varies from the baseline and calculate how many people are present based on that.
Well, thats the gist anyway.
Firecodes based on "maximum occupancy per square foot" might also be a useful line of inquiry.
devapsarl405252dI can think about 3 thermal camera with image proccessing. Then u count the red continuous spots
Maybe you can put 2 senser devices at entrances and detect in wich order they get fired, and know it it is a +1 or -1 (entering room or getting out)
In the start and end of the day it must be zero, so u have 2 error correcting numbers.
Wisecrack3788251dMight have issues on cold days just so you know.
Sure theres a work around though.
Sounds like a super fun project.
I wish I had a hackerspace (god I hate that term), in my area that didn't cost a boatload of money for membership.
ishank-dev640249d@sbiewald how do you get the access to other's Bluetooth /wifi residing far away from you?
What I wanted was --
"search for any place on the internet and see how busy that place is at a particular point in time."
But i found a pre existing modified google places api which does the exact same job!
