Toshiba Electronic Devices & Storage Corporation announces that DENSO Corporation (DENSO) is implementing Visconti™4, its latest image recognition processor dedicated to automotive applications, in next-generation active safety systems based on front cameras.Visconti™4 is an advanced, multi-engine road safety solution that provides drivers with real-time analysis of road conditions and potential hazards.
Electronic systems are playing an increasingly important role in driving, including advanced driver assistance systems and support for autonomous vehicles, and particularly in promoting road safety. The latest version of the influential European New Car Assessment Programme (Euro NCAP), the EU-backed safety standard, adds criteria for evaluating anti-collision features that improve the protection of cyclists and pedestrians.
The Visconti™4 image recognition processor is equipped with eight media processing engines, allowing it to run eight applications simultaneously. It can detect and analyze camera-generated images and recognizes traffic lanes; nearby vehicles, both stationary and moving; traffic signs and billboards; the headlights of oncoming vehicles; and the most vulnerable road users of all: cyclists and pedestrians.
Visconti™4 has twice the processing engines of its predecessor, Visconti™2, which DENSO has used since 2015. It also integrates a new image recognition algorithm, the enhanced Co-occurrence Histograms of Oriented Gradients (CoHOG)[1], which provides better processing of luminance differences between objects and their backgrounds for improved pedestrian detection at night and in low-light conditions.
Toshiba and DENSO are also collaborating on artificial intelligence (AI) technology, developing intellectual property deep neural networks (DNN-IP) for image recognition, and plan to bring this cutting-edge technology to future additions to the Visconti series.
The global market for vehicle-mounted cameras is expected to reach approximately US$9.6 billion in 2021[2]. Toshiba is committed to responding with automotive semiconductor solutions that pursue traffic safety.
