How to simply analyse image with Arduino ?

Projects General Guidance

Hi !
I have currently a student engineering projet. It consists of knowing the density (approximatively) of people on a video.

I thought about an Arduino Uno + a simple camera shield (costing around 10$)

I know that image analyse is very difficult on an Arduino Uno, but the code seems very simple.
I thought about just make a simple difference between the image recorded by the cam and the background (saved when there is no movement for a moment), with maybe a lower resolution.
I know that OpenCV provide open source codes in different langages for image analyse.

If someone can help me ...

Not possible with ATMega-based Arduinos. They have too little memory to store images.

Come off it the code is very very complex.

That is called frame subtraction, it will not help you do what you want.

Nice thing to know, know this also:-

  1. It is a bit crap
  2. You can't run it on an Arduino

You have stumbled into the wrong forum (or group thereof).

You evidently want the Raspberry Pi forums.
