According to foreign media reports, Hitachi announced the development of a stereo camera, which combines long-distance object detection and wide-angle vision, without the need for millimeter wave radar, to enable the vehicle to conduct automatic emergency braking (AEB) at intersections. (photo source: Hitachi official website) with the continuous growth of global vehicles, the market demand for technologies to improve driving safety is increasing. In 2020, NCAP (New Car Assessment Program) will include AEB in its vehicle safety performance assessment standards. When turning at the intersection, vehicles need to be equipped with sensor technology with horizontal and wide-angle vision to detect pedestrians and avoid accidents. To achieve this, it is necessary to continuously detect the vehicle ahead, and at the same time, it is necessary to have a high-pixel CMOS (complementary metal oxide semiconductor) image sensor, camera sensor, or a combination of multiple sensors, including a radar to detect surrounding areas or distant objects. Compared with the traditional stereo camera, the new stereo camera has a larger horizontal field of vision, and the image detected by the left and right cameras is shifted, so the detection range is wider. Its viewing angle is three times wider than the traditional stereo camera, and it supports automatic emergency braking at intersections, while still maintaining ACC (adaptive cruise control) function. The technology was jointly developed by Hitachi automobile and the R & D team of Hitachi, which changed the detection methods of the center and periphery of the detection range. This stereo camera has few components, which can detect pedestrians and cyclists with high accuracy and estimate the distance between them and vehicles, so as to improve the safety of intersections. This stereo camera integrates a variety of functions seamlessly, including the use of binocular vision for centralized binocular detection, the use of peripheral monocular vision for time series image processing, the realization of 3D object detection, and the use of machine learning methods to store recognition patterns. In addition to developing technologies to improve stereo camera performance, Hitachi Group will continue to provide equipment and solutions to drive the actual deployment of vehicles and connected vehicles.
