Magic Leap 1 COVID-19 Detection System

Build your own free Magic Leap 1 COVID-19 Detection System. This project uses Magic Leap 1, TensorFlow, Unity & Raspberry Pi 4.

Introduction

The Magic Leap 1 COVID-19 Detection System 2020 uses Tensorflow 2, Raspberry Pi 4 & Magic Leap 1 to provide a spatial computing detection system.

The project uses the COVID-19 Tensorflow DenseNet Classifier a Tensorflow implementation of DenseNet and the SARS-COV-2 Ct-Scan Dataset, a large dataset of CT scans for SARS-CoV-2 (COVID-19) identification created by our partners at Lancaster University, Plamenlancaster: Professor Plamen Angelov Centre Director @ Lira, & his researcher, Eduardo Soares PhD.

We use the trained model from COVID-19 Tensorflow DenseNet Classifier with the COVID-19 Tensorflow DenseNet Classifier For Raspberry Pi 4 and serve an API endpoint that exposes the Artificial Intelligence classifier allowing Magic Leap 1 to communicate with it.

DISCLAIMER

This project should be used for research purposes only. The purpose of the project is to show the potential of Spatial Computing, Artificial Intelligence, and the Internet of Things for medical support systems such as diagnosis systems.

Although the classifier used in this project is very accurate and shows good results both on paper and in real world testing, it is not meant to be an alternative to professional medical diagnosis.

Developers that have contributed to this repository have experience in using Artificial Intelligence for detecting certain types of cancer & COVID-19. They are not a doctors, medical or cancer/COVID-19 experts. Please use these systems responsibly.

Prerequisites

Before you can install the Magic Leap 1 Unity COVID-19 Detection System, there are some prerequisites.

HIAS Server

If you are going to be using the full system you will need to install the HIAS server. Follow the HIAS Installation Guide to complete your HIAS server setup.

If you chose not to use the full system, steps are provided in this tutorial that will allow you to use the system without a HIAS installation.

COVID-19 Tensorflow DenseNet Classifier

If you want to train your own Artificial Intelligence required to detect COVID-19, you will need to complete the COVID-19 Tensorflow DenseNet Classifier tutorial. If you would like to use the pre-trained model we have provided, you can skip to the next step.

YOU MUST USE THE SAME TRAIN AND TEST DATA AS THE TUTORIAL SPECIFIES

The test data provided in the Magic Leap 1 Unity COVID-19 Detection System requires the same model to be used.

COVID-19 Tensorflow DenseNet Classifier For Raspberry Pi 4

The COVID-19 Tensorflow DenseNet Classifier For Raspberry Pi 4 hosts a local server on a RPI4 allowing images to be classified remotely. In this project we use the AI model trained in the COVID-19 Tensorflow DenseNet Classifier, but we also provide the pre-trained model so that you can use the classifier “out of the box”.

Regardless of whether you choose to train your own model or use the pre-trained model, you will need to complete the COVID-19 Tensorflow DenseNet Classifier For Raspberry Pi 4 tutorial as this is the project that creates the classifier that the Magic Leap 1 will interact with.

Clone the repository

Clone the COVID-19 AI Classification repository from the Peter Moss COVID-19 AI Research Github Organization.

To clone the repository and install the COVID-19 Tensorflow DenseNet Classifier For Raspberry Pi 4, make sure you have Git installed. Now navigate to the home directory on your device using terminal/commandline, and then use the following command.

$ git clone https://github.com/COVID-19-AI-Research-Project/Magic-Leap-1-Detection-System.git

Once you have used the command above you will see a directory called COVID-19-AI-Research-Project in your home directory.

ls

Using the ls command in your home directory should show you the following.

Magic-Leap-1-Detection-System

Navigate to Magic-Leap-1-Detection-System/Projects/Unity directory, this is your project root directory for this tutorial.

Developer Forks

Developers from the Github community that would like to contribute to the development of this project should first create a fork, and clone that repository. For detailed information please view the CONTRIBUTING guide. You should pull the latest code from the development branch.

$ git clone -b "0.2.0" https://github.com/COVID-19-AI-Research-Project/Magic-Leap-1-Detection-System.git

The -b “0.2.0” parameter ensures you get the code from the latest master branch. Before using the below command please check our latest master branch in the button at the top of the project README.

Installation

Below you will find the steps required to setup for Magic Leap development.

Magic Leap Basics

Follow the Magic Leap Developer Setup guide to install the required Magic Leap development tools.

Unity 2019.3.4f1

For Magic Leap apps you need Unity 2019.3.4f1. Head to the Unity 2019.3.4 page and download and install the Lumin Target Support exe.

Open Magic Leap’s Lab and click on the Launch button for Unity Hub.

Unity Hub will now open.

Go to the Installs tab in Unity Hub and select Unity 2019.3.4f1 (LTS), click next and continue until Unity 2019.3.4f1 (LTS) is installed.

Click on the ADD button. This will open Windows Explorer allowing you to navigate to the project and import it.

To import Magic Leap 1 Unity COVID-19 Detection System into Unity Hub, navigate to the Magic-Leap-1-Detection-System/Src directory and click Select Folder.

Now for some configuration. In Unity, open File->Build Settings and change the target to Lumin if not already done.

Now go to Edit->Preferences and head to the Lumin section. You now need to use the browse button to navigate to your version of the Lumin SDK. It should be in the path C:/Users/YourUser/MagicLeap/mlsdk/v0.24.1.

Next you need to add your Magic Leap certificate. Follow the Get a Developer Certificate guide on Magic Leap’s website.

Once you have your certificate you need to add it to your Unity project. Go to Edit->Project Settings->Publish Settings and click Sign Package then click the button  to open Explorer, navigate to the location you saved your certificate to and select the folder.

Magic Leap 1

You now need to setup your device for development. Power up your Magic Leap 1 and head to Settings->Device->Developer Mode. You need to Enable Developer ModeAllow Untrusted Sources, and Enable MLDB Access.

Usage

After following the installation guide you should now have all of the required tools installed. Use the following guides to start using the Magic Leap 1 Unity COVID-19 Detection System.

Unity Hub

Open Magic Leap’s Lab and click on the Launch button for Unity Hub.
