3D sensing platform targets access control, smart video security
AI vision processor company Ambarella (Santa Clara, CA), photonic products company Lumentum (San Jose, CA), and semiconductor supplier ON Semiconductor (Phoenix, AZ) have announced a joint 3D sensing platform for the development of intelligent access control systems and smart video security products such as smart video doorbells and door locks.

The platform is based on Ambarella's CV25 CVflow AI vision system on chip (SoC), structured light powered by Lumentum's VCSEL technology, and ON Semiconductor's AR0237IR image sensor. Unlike traditional structured-light solutions that need to use both an infrared (IR) camera and a separate RGB camera, the new platform, say the companies, leverages a single ON Semiconductor AR0237 RGB-IR CMOS image sensor to obtain both a visible image for viewing and an infrared image for depth sensing.

In addition, the Ambarella CV25 AI vision SoC powers depth processing, anti-spoofing algorithms, 3D facial recognition algorithms, and video encoding on a single chip, significantly reducing system complexity while improving performance.

"We are delighted to partner with Lumentum and ON Semiconductor to deliver a hardware platform for the next generation of intelligent access control systems and video security devices," says Fermi Wang, president and CEO of Ambarella. "Powered by Lumentum's VCSEL solution, ON Semiconductor’s RGB-IR technology, and our CV25 SoC, it delivers 3D sensing with reduced system complexity as well as improved reliability and security. We look forward to seeing the innovative products our customers will build with this hardware platform."

Gianluca Colli, vice president and general manager of the Commercial Sensing Division at ON Semiconductor says, "ON Semiconductor’s RGB-IR sensor technology enables single sensor solutions to provide both visible and IR images in security and vision IoT applications. Ambarella's CV25 computer vision SoC, with its next-generation image signal processor (ISP), brings out the best image quality of our RGB-IR sensor, while providing powerful AI processing capability for innovative use cases in security applications."

Dr. Andre Wong, vice president, product line management, 3D Sensing at Lumentum says, "Lumentum has worked to enable diverse applications of our VCSEL technology into next-generation 3D sensing products. We are excited to partner with Ambarella to help expand the use of 3D sensing in new applications including video security and more broadly AI vision."
