PEOPLE INSIDE

At meal time, there are too many people in a restaurant. So we have to wait in the restaurant. We want to check the number of indoor people in advance. PEOPLE INSIDE is a real-time people counting system using ultrasonic sensors. Our system aims to measure indoor congestion metrics. You can check the number of people with application.

Our Purpose

We are focusing on three main purposes.

purpose

Quick Start

git clone https://github.com/PEOPLE-INSIDE/people-inside

Getting Started

Installation Environment

Before you start, make sure the environment fits perfectly.

  • ultrasonic sensorㅡ need 4 ultrasonic sensors which parallel aligned in pairs. You must prepare inexpensive one which like HC-SR04 we used.
  • Wifi Shieldㅡ necessary to send data to the application.
  • Serverㅡ
  • Applicationㅡ required to view the processed data directly.

architecture

Basic Principle

If the A sensor detects a person first, it means IN. And the reverse, it means OUT.

principle

How To Use

  • Classification Algorithmㅡ Classification algorithm that classifies Serial datas which one is IN and OUT.
  • Random Forestㅡ Machine Learning with data sets what we collected.

You can choose one method that you want to use.
