IOT Based Face Recognition Robot

Abstract

This proposed system deals with the idea of secure locking automation utilizing IOT for door unlocking system to provide essential security to our homes, bank lockers and related control operations and security caution through the admin panel. It uses an image capturing technique in an embedded system based on raspberry pi server system. RPi (Raspberry pi) controls the video camera for catching it for turning on green light and the signal is sent to the admin through IOT. Then admin provide authentication signal to the door for unlocking door through a relay. The module contains a secured face recognizer for automatic door unlocking. The camera catches the facial picture and compares it with the image which is stored in the database. If the picture is found in the database, then the door lock opens after authentication otherwise it will lock the door and turn on RED light.

Existing System

The existing system proposed a door lock access system which comprised mainly of three subsystems: namely face detection, face recognition and automatic door access control. Face recognition is implemented by using the Principal Component Analysis (PCA). The door will open automatically for the known person due to the command of the microcontroller. On the other hand, alarm will ring for the unknown person.

Proposed System

In this proposed system, RPi (Raspberry pi) is used to control the video camera for catching face images for turning on green light and the signal is sent to the admin through IOT. Then admin provide authentication signal to the door for unlocking door through a relay. The module contains a secured face recognizer for automatic door unlocking. The camera catches the facial picture and compares it with the image which is stored in the database. If the picture is found in the database, then the door lock opens after authentication otherwise it will lock the door and turn on RED light.
