First line of defence against Covid-19 Using Jetson Nano?

Aegis - Your First Line Of Defence
A complete Turnkey Security solution that scans the area for security threats and risks to safeguard public health.

Since the Covid-19 lockdowns began in the US, the focus of business enterprises and public facilities has suddenly shifted from service to keep people safe from the virus. The guidelines from the CDC and others - social distancing, mask-wearing, etc. - are straightforward in concept, but demonstrating compliance with these guidelines in a quantitative way is difficult. Many businesses have enforced masks and printed signs in their stores; however, human negligence on any of those guidelines can severely undermine public safety and consumer trust.

No single tool exists for providing real-time, actionable intelligence around the risks of your employees, customers, and overall business. We’ve conducted dozens of interviews with small business owners and here are some of the questions we hear them struggling to answer in a meaningful way:

  • How many people in my store today had masks on?

  • Do I have too many people in the store?

  • Are people observing the social distancing guidelines?

  • If someone gets sick and blames it on us, what evidence can we provide to demonstrate responsible behaviour?

Supporting technologies exist in a piecemeal fashion, but they are too complex or expensive for most businesses. Our goal is to address all of these problems with a single, low-cost, turnkey solution that can take advantage of existing surveillance systems and AI infrastructure. Hence was born - Aegis!

Technology Solution: Aegis

Aegis is the ultimate public health tracker and a business’ first line of defence against the invisible enemy, Covid-19, as well as other public health threats. It is a complete turnkey (hardware and software) health and safety solution that scans the area for threats and risks to public health and delivers real-time information regarding threats, risks, and compliance.

The underlying platform uses state-of-the-art computer vision algorithms to receive and process video feeds from its built-in camera (or, soon, any existing IP camera or CCTV camera). Once received, the video evaluates numerous criteria that can affect public health and risk, including mask-wearing rates, social-distancing violations, and people-density management, to better understand the risk of transmission among individuals in a specific location.

A live video feed with augmented reality overlays is on a mobile-first, web-based user interface along with key metrics and trends over time. Aegis also provides real-time alerts and actionable recommendations so users can take immediate action to reduce risk.

How Aegis works.

Aegis emphasizes the importance of the CDC guidelines and incorporates a compliance scorecard; this feature uses a combination of Aegis AI technology as well as self-certification by the business owner to determine if the business is complying with the recommended CDC guidelines.

Over the Summer, our team at Ekta worked with a small team of interns, to develop Aegis. Our goal is to address all of these problems with a single, low-cost, turnkey solution that can take advantage of existing surveillance systems and AI infrastructure. An all-in-one product to allow businesses to focus on service, without compromising on public safety.
The Aegis Project consists of the following components -

Hardware: A custom CAD enclosure that can be mounted on any surface

Software: Web Application with a live video feed Computer vision algorithms to receive and process video feeds from its built-in camera (or, soon, any existing IP camera or CCTV camera). Filters overlayed on the video feed that evaluates the following criteria which can affect public health

  • Mask-wearing rates

  • Social-distancing violations

  • People-density management

Why Aegis is better than existing solutions and products in this domain

To put it succinctly: Aegis is better, cheaper and more effective than existing solutions. Our human-centred design and product-focused approach make this a fully operational system with good performance, the right set of functionality and metrics, and an excellent user experience.
Our solution, built on the IBM cloud, is capable of tapping into any camera feed. In addition, we have developed a turnkey hardware option based on the NVIDIA Jetson Nano board for edge processing and a custom-designed CAD enclosure. Lastly, we believe our solution is at least one order of magnitude cheaper than alternatives.
Our platform is designed with flexibility in mind, so it will be easy to add additional sensors and machine learning models (e.g., temperature, IR cameras, firearm detection, etc.) into the product.

Lastly, our diverse and talented team is positioned to take this to the next level and includes an MIT engineer, an active duty army 68W Healthcare Specialist, and a product designer from the Art Institute of Chicago along with university student participation. We believe this team is unique, special and ready to lead in the response to the COVID-19 threat.
With continued development, Aegis’ capabilities will expand to include tracing of contact hotspots in a specific location (e.g countertops, glass surfaces etc.), temperature checks and expansion to other security applications.

Teardown video now available!!!

We use an Nvidia Jetson Nano board, ribbon cable cam, custom 3d-printed enclosure, heatsing and Noctua fan, and a COTS mounting bracket. The software is a remastered version of the Jetson OS so that we can flash it directly to an SD card and boot right away with all the custom and necessary libraries pre-built.
