A project using a Model-Based System Engineering approach to develop a face recognition device which greets people and alert the owner in case of intrusion in his home.

PolitelySecureDevice

The goal is to develop a device greeting people around based on face recognition. A later version will include the capability to alert the owner/tenant when there is intrusion.
The development is conducted using a Model-Based System Engineering approach on the software Capella to support the elicitation of the system needs and the design of an appropriate architecture.

Requirements

• Capella 5.2.0 (to be able to open the model with Capella)

System Model

Logical Architecture

The Logical Architecture describes the main architectural concepts. On the diagram below, the high-level architectural components and their functionalities are presented. Some design decisions are also made such as the choice of an audio message rather than a text message to greet people.

Physical Archtitecture

The Physical Architecture describes the technological choices. Here we will make use of a RaspberryPi 4 and a camera to detect and recognize faces.

Implementation of "Greeting"
