Kit enables eight cameras and mirrors for ADAS

Developing and evaluating software for viewing applications can be quicker, says Renesas Electronics, using its advanced driver assistance systems (ADAS) view solution kit.

The R-Car H3-based second generation kit has up to eight cameras. According to the company, it realises next-generation electronic mirrors (cameras to check surroundings, monitor the driver and provide surround view systems simultaneously).

 The automotive cameras allow developers to collect data from the environment for sensor fusion, whereby information from cameras and radar is combined and processed for vehicles to recognise surroundings. This facilitates autonomous driving and ADAS applications, together with 360 degree surround view. Camera-based electronic mirrors will allow object detection, and viewing angles to be modified.

 The ADAS view solution kit includes the company’s R-Car Starter Kit Premier automotive software development environment, which is based on the R-Car H3 SoC, featuring Imagination Technologies’ PowerVR GX6650 GPU. It also has the required sample application software for ADAS application software development and calibration software to correct distortion of the images for surround view. Dynamic surround view can be achieved by using the sample application software in binary code and the GPU of the R-Car H3 that enables arbitrary viewpoints. Static surround view can be achieved without a GPU or CPU by using the calibration software that corrects image distortion and the sample software in source code. The software for static surround view uses Renesas’ image rendering (IMR) technology.

IMR technology enables low-cost surround view with pre-defined viewpoints, in case the GPU has to be used for other applications or to evaluate a static surround view. The IMR is also used for zooming and perspective adjustment for electronic mirrors and driver monitoring cameras.

Up to eight minicube cameras from Integrated Micro-electronics use 1.3Mpixel automotive sensors from OmniVision Technologies. They are connected via a high speed Gbit multimedia serial link (GMSL) serialiser and a quad deserialiser from Maxim Integrated.

 Video processing units in the R-Car H3 allow the composition of surround view with overlay of smart camera pictures at ultra-high definition resolution (UHD).

 The ARM Cortex-A57/A53 cores provide 40,000 DMIPS enhanced processing for the application and computer vision implementations. OpenCL on the GPU provides the option to implement cognitive functionality, bringing additional safety features.

 The kit is scheduled to be available from January 2017 and will include the ADAS Starter Kit Premier as well as four cameras, with four additional cameras available as an option.
