Duo collaborate on automotive in-cabin sensing

This advanced perception supports safety and convenience features including Driver Monitoring Systems (DMS), Occupant Monitoring Systems (OMS), child presence detection, object recognition, gesture control, and activity prediction.

ST’s 2.3 Megapixel VG5761 Global-Shutter sensor features high linear dynamic range of up to 98 dB for sharp, crisp images. The sensor can capture images inside a vehicle under all lighting and environmental conditions.

Combined with Eyeris’ in-cabin sensing technology, the sensor can be used for Eyeris’ DMS with accurate eye-gaze tracking, especially from non-frontal camera locations such as rearview mirror, overhead console, and centre stack areas.

In parallel, the sensor also enables Eyeris’ OMS with accurate tracking of body key-points, height, width, size, posture, movements, and orientation.

Furthermore, the ST sensor enables Eyeris for accurate child presence detection, and recognition of common vehicle interior objects under the widest range of lighting conditions. The technological integration from ST and Eyeris delivers substantial in-cabin safety, comfort, and convenience benefits for all occupants.

“ST is committed to making vehicles and e-mobility safer and working with Eyeris on their in-cabin sensing AI using our Global-Shutter imaging technology is a valuable example of what top innovators focused on an important challenge can do,” said Dominique Barbier, Head of U.S. Technical Marketing, Imaging Division, STMicroelectronics.

The VG5761 Global-Shutter image sensor offers two memory zones that allow double-image storage which, in addition to contributing to the high dynamic range, supports background removal without lag effects and additional processing by the host system.

In its RGB-IR version, ST’s image sensor uses high MTFs (Modulation Transfer Functions) at near-infrared (IR) wavelengths as well as through the RGB channel to monitor the full in-cabin scene under a broad range of lighting environments while featuring the capability to accurately analyse interior safety-critical Regions Of Interest (ROIs) with great detail – like the driver’s eyes and the occupants’ body key-points — to detect the earliest signs of driver drowsiness or distraction and occupants’ body posture.

The sensor’s high-performance capability combined with Eyeris’ AI-based algorithms help automakers personalize restraint controls and passive vehicle safety systems.

“In combining Eyeris’ portfolio of Deep Neural Networks with ST’s Global-Shutter imaging technology, we’ve assembled a state-of-the-art solution for in-cabin sensing and a useful template for the industry towards advancing cockpit safety and comfort,” said Modar Alaoui, founder and CEO, Eyeris.
