Nexar——打造下一代視覺資料平台

作者 Gayathri (G) Radhakrishnan - 2020-04-30

Before these times of social distancing, the average American commuter wasted 54 extra hours a year in traffic delays resulting in lost productivity and higher fuel consumption. 這些成果結合了由於駕駛不慎所造成的受傷和事故,以及對交通模式和建築活動的改變,都指向了對於更完善的道路安全解決方案的強烈需求。

When we first met with Nexar to evaluate a potential investment, we were truly impressed with both the team and the sophistication of Nexar’s platform. Nexar’s focus on addressing the problem of road safety and traffic congestion from multiple vantage points resonated well with us. The company has also built an extensive vision-based data platform, which made the prospect even more exciting. So, yes, we did decide to invest.

To understand why, let me peel a few layers of their solution so you can see its value. Those layers include road safety, mapping, connectivity and privacy.

Road safety is important to consumers — and also insurers

For the consumer leveraging the Nexar dashcam, the platform provides real-time alerts on road conditions, blocked lanes and other potential problems. And in the event of collisions, the platform allows drivers to submit claims with their insurance companies with a single tap. This capability could lead to discounts and other incentives for safe drivers. For the insurance company, it means money saved from less fraud, faster resolution of insurance claims and superior service for their customers.

Mapping data is critical to making autonomous mobility a reality

Delivery companies are said to be losing $6 billion annually due to a lack of accurate map information such as traffic signs, construction closures, detours, fuel costs, missed or delayed delivery and parking availability.

The world is ever-changing, and mapping it is definitely not a one-and-done effort.Nexar’s deep learning and computer vision-based platform are aggregating anonymized street-level data that has multiple areas of application. Nexar’s data has grown tenfold since launch, and now Nexar regularly indexes an astonishing 50% of U.S. roads every week!

Today, Nexar’s Live Map is the company’s answer to Google Street View — but with street-level images taken minutes ago by drivers on the company’s network.

Smart transportation begins with a connected vehicle network

Nexar’s CityStream feeds an essential part of the smart city infrastructure to enable incident response, traffic optimization and traffic rerouting. The Regional Transportation Commission (RTC) of Nevada, called its pilot using Nexar City Stream a groundbreaking project. Nexar’s artificial intelligence (AI) platform helps provide near-real-time road inventory tracking for customers like the RTC and determine the effects of construction cones and lane closures on traffic.

We are very excited about the launch of Nexar’s new data platform, Nexar Virtual Camera, which pulls a feed of anonymized frames from any location on the Nexar network. Nexar will be making the platform available for free during the COVID-19 pandemic to help institutions monitor key areas such as traffic at hospitals or crowd levels in public spaces.

And “what about privacy?” you ask

What was clear from the very first meeting was the importance the team placed on data privacy. The Nexar platform leverages computer vision and machine learning to carefully detect and blur out faces and license plates so that neither people nor cars can be identifiable systematically.

What about location data? Does Nexar track users the entire duration of their rides? The simple answer is no. By using federated learning, the Nexar platform randomly picks frames from multiple users, so a single user and location cannot be tracked. Nexar is also very clear that the user owns the data — what Nexar receives is just the blurred and anonymized data that has no link to the user.

Why did Micron invest?

Micron is powering the next generation of infrastructure that makes AI possible. We are focused on enabling the “intelligent edge” where the data resides. The Nexar team has a multidisciplinary focus on optimizing the platform across hardware, software and the AI engine. An investment in Nexar allows to be a part of this fast-evolving space. And we are excited to be an active part of Nexar’s journey!
