OmniVision Technologies, Inc. introduced the OV2311, an automotive 2-megapixel, 3 μ global shutter image sensor designed for the next generation of driver monitoring systems. Leveraging OmniPixel3-GS global shutter technology and near-infrared imaging capabilities, the OV2311 offers manufacturers of semi-autonomous vehicles a high-performance, cost-effective, ISO 26262-ready imaging solution for vision-based driver monitoring systems.
According to the National Highway Traffic Safety Administration (NHTSA), distracted driving is one of the major causes of car accidents. To combat distracted driving, the automotive industry is ramping up its development of driver monitoring systems and vehicle co-pilot applications, which in combination can allow the on-board computer to seize or relinquish control of the vehicle, based on the driver’s state. NHTSA defines this setup as level 3 autonomy. Currently only available for luxury vehicles, these systems are expected to become a standard safety feature in the near future.
“The demand for driver monitoring systems is expected to increase significantly as more affordable technologies allow advanced semi-automated features to transition from high-end to mainstream vehicles,” said Jeff Morin, automotive product marketing manager at OmniVision. “Possessing the same capability customarily found in much larger and more expensive sensors, the OV2311 aims to bring advanced driver monitoring systems to the masses by delivering high-level, cost-effective performance in a compact form factor.”
Vision-based driver monitoring systems in semi-autonomous vehicles require highly sophisticated eye-tracking technology and imaging capabilities. The OV2311 achieves high near-infrared quantum efficiency to minimize active illumination power. The sensor’s 1600 x 1300 resolution format is designed to fit a driver’s head box to ensure reliable monitoring regardless of that driver’s height or seat position. Packaged in OmniVision’s ultra-compact automotive chip-scale package (a-CSP), the OV2311 can be discreetly installed anywhere inside the automobile’s cockpit.
The OV2311 is available for sampling, with volume production expected in the fourth quarter of 2017.
