Toshiba image processors make driving safer

Toshiba America Electronic Components, Inc.  has taken the wraps off a new series of image recognition processors – called Visconti 3 – aimed at making automotive use safer. The Visconti series is designed for use in camera-based vision systems for advanced driver assistance systems.

The company claims that it will detect and recognize lanes, vehicles, traffic lights, signs and pedestrians in real time, both day and night. It can process image data from multiple camera inputs frame-by-frame and then outputs results to an LCD panel.

The Visconti 3 (TMPV7528XBG), integrates an ARM Cortex-A9 MPCore to manage the connections to other automotive systems, including navigation, smartphone, driver assistance and the Cloud.

The core includes a single/double-precision floating point unit that is claimed to improve performance of image processing by handling the mathematical computations required to analyze large volumes of image data from the video source, frame-by-frame in real time, in some of the algorithms.

The company said the new family can be used to monitor and detect a wide range of driving conditions: Forward Vehicle Detection and Collision Warning, Forward and Backward Collision, Real-time Traffic Lines, Lane Departure Warning, Rear and Front Pedestrian Detection, Left/Right Turn Awareness, Obstacle Vehicle Detection, Traffic Sign Detection, Top-view Parking Assistance, and Driver authentication and monitoring.

The Visconti Series incorporates accelerators that make use of Histogram of Oriented Gradients (HOG) features, enabling real-time pedestrian detection both in night time and daytime. HOG features are suitable for detection of humans due to its robustness regardless of lighting changes or small deformations.

The Visconti 2 and 3 Series support high-resolution color cameras suitable for applications requiring color recognition, such as detection of traffic lights and signs. Up to four cameras can be simultaneously connected to the Visconti 2 and 3 Series making it suitable for a bird's-eye view parking assistance system that uses images synthesized from image data captured by four cameras.

They incorporate four image processor cores operating at 0.266 GHz, and up to six image processing accelerators, enabling fast object detection with enhanced performance. At 0.266 GHz, each image processor core achieves computing performance equivalent to that of 3 GHz notebook PC processors and realizes low-power consumption of less than 2W.

The Visconti3 Series is backward compatible with the Visconti2 series and can run the OS and other software needed for enhanced connectivity with car navigation, smartphone and cloud applications by adding the ARM® Cortex™-A9 MPCore.

The Visconti3 Series incorporates a single/double-precision Floating Point Unit (FPU) that simplifies optimization of the imaging algorithms so that software developers can reduce their overall design time.

Toshiba said it expects that samples of the Visconti 3, TMPV7528XBG, will be available in April 2013.<
