ABI Says Sensors, Semiconductors, Autonomous Driving, and Regulation Are Spurring the ADAS Revolution
Advanced Driver Assistance Systems (ADAS) are essentially driven by a sensor fusion revolution combining radar (forward looking obstacle detection), camera (pedestrian detection, lane keeping, driver monitoring), infra-red (night vision), ultrasonic (automated parking), and LiDAR sensors.
While radar will remain a key technology, boosted by the 79 GHz spectrum band expected to become available globally, camera sensors and machine vision technology hold the promise of propelling ADAS into the mainstream because of its lower cost, flexibility, and multi-purpose character.
OmniVision Technologies Inc. announced what it said is the automotive industry’s first backside illumination (BSI) image sensor, the OV10640, and a new companion processing chip, the OV490.
The OV10640 is said to deliver industry-leading sensitivity and high dynamic range (HDR) of up to 120 dB in highly compact automotive-grade packages, while the OV490 enables high-quality image and video processing. The OV10640’s enhanced performance and OV490’s optimized processing capability bring crisp, clear images and video to next-generation advanced driver assistance systems (ADAS) across a wide range of vehicle platforms.
Targeting advanced driver assistance systems (ADAS), OmniVision Technologies Inc. launched the single-chip OV10626 AutoVision sensor, which is said to combine exceptional high dynamic range (HDR) while maintaining excellent low-light sensitivity.
The OV10626 supports both NTSC analog and digital outputs as well as dual dynamic overlay functions. The sensor’s color HDR of up to 120 dB and low-light sensitivity of 15 V/Lux-sec ensure that clear, high-quality images are captured, even in extremely challenging lighting conditions.
Platforms reduce design risk of instrument clusters, surround view systems and infotainment head units
At SAE Convergence 2010, Xilinx, Inc. announced three automotive Targeted Design Platforms to help system designers use Field Programmable Gate Array (FPGA) technology to meet the performance and integration requirements of driver assistance, driver information, and infotainment systems.
Xilinx said the platforms, designed for use with Xilinx® Automotive (XA) Spartan®-6 FPGAs, reduce development risk by providing a framework from which designers can focus on customization and product differentiation.
Taiwanese imaging systems provider Altek Corp. has selected AutoVision image sensors from OmniVision Technologies, Inc. for Altek’s Eagle View 360° surround viewer and lane departure warning system (LDWS), which is being implemented by a large Asian automaker.
The automotive-qualified Eagle View vision system provides true 360° coverage of the area around a vehicle. Multiple AutoVision CMOS cameras installed around the vehicle’s perimeter provide real-time video images of the vehicle’s surroundings. The Eagle View system, which is a virtual top-down projection system, processes and synthesizes the video images to provide a clear 360° view of the vehicle’s surroundings. The system also allows drivers to switch to rear-view camera mode when reversing the vehicle.
July 8, 2009 — OmniVision Technologies has introduced a 1-megapixel image sensor specifically tailored for advanced automotive imaging applications. The AutoVision OV9715 camera features a zero degree micro lens shift and 1280 x 800 pixel array for advanced forward-looking and extreme wide angle field of view vision applications such as 360 degree bird’s eye view and parking assistance systems. The OV9715 is also optimized for use in automotive vision and sensing system combinations, such as rear view and trajectory based lane departure warning systems.
