ON Semiconductor, at the on-going AutoSens 2019 conference has featured a complete in-cabin monitoring system inclusive of driver monitoring and occupancy monitoring functions. The demonstration included multiple sensor types - the 1 Megapixel (MP) Global Shutter AR0144AT image sensor and three 2.3 MP RGB-IR image sensors. The multi-camera system utilizes Ambarella’s CV2AQ SoC that processes real-time high-quality RGB-IR video and integrates Eyeris’ AI software performing complex body and facial analytics, passenger activity monitoring, and object detection.
Driver and occupant monitoring applications require the ability to capture images in variable lighting from direct sunlight to pitch black conditions. With outstanding NIR response, the RGB-IR CMOS image sensor technology provides full HD 1080p output using a 3.0 µm backside illuminated (BSI) and three-exposure HDR. Sensitive to both RGB and IR light, the sensors are able to capture color images in daylight and monochrome IR images with NIR illumination.
Important safety systems such as child presence detection, as well as convenience functions, are next-generation features that customers are now developing. ON Semi’s broad portfolio of automotive sensors is engineered to deliver these capabilities for in-vehicle applications. Furthermore, strong collaboration between sensor, processor and software companies is imperative to optimize performance and accelerate time-to-market of these in-cabin systems.
According to Ambarella VP of Marketing Chris Day, working with ON Semiconductor and Eyeris to realize this demonstration provides a great example of companies with industry-leading technologies cooperating to drive innovation in the automotive sector. Ambarella’s CV2AQ SoC combines its proprietary CVflow DNN engine and high-performance image processing. Paired with ON Semiconductor’s diverse in-cabin sensor portfolio and Eyeris’ scene understanding AI, Ambarella has been able to achieve a system capable of meeting the industry’s growing demand for vision-based in-cabin solutions.
ON Semiconductor is also demonstrating other cutting-edge technologies at its booth at the AutoSens event, being held in Brussels from September 17-19. In addition, Geoff Ballew, Senior Director of the Automotive Sensing Division is participating as a conference speaker, providing an “Overview of the challenges and requirements for state-of-the-art sensors across the major sensor types.”
