R-Car V2H

Overview

The R-Car V2H is Renesas’s first R-Car ADAS device.
The functions required for ADAS are packed in a single chip, which also allows reduced power consumption. The R-Car V2H enables each camera to prevent oversight with Renesas' image recognition technology and to switch the field of view depending on the situation. The R-Car V2H delivers the smartest high-resolution surround monitoring systems having enhanced visibility.

Features

  • Provides sophisticated surround monitoring system

The R-Car V2H has six IMR channels which are used as dedicated hardware that converts data input from cameras to panoramic stereoscopic video which is obliquely viewed, and provides clear HD video.

The incorporated IMP-X4 (4th generation image recognition H/W) expands the image recognition library to include an open source library (OpenCV) and improves the software development efficiency.

Offers ready-to use solutions.

Provides sample code and board support packages useful for application development and accelerates application samples for customers by exploiting the ecosystem of the R-Car family products.

System Block Diagram

Image recognition or conversion is performed by the dedicated H/W, and consequently the robust (or high performance) CPU allows users to add their own functionality.
