Renesas Electronics have announced their collaboration with Dibotics to develop an automotive-grade embedded solution for LiDAR processing used in ADAS and automated driving applications.

The jointly-developed solution will enable system manufacturers to develop real-time 3D mapping systems with high level functional safety (FuSa) and low-power consumption.
LiDAR processing today requires an efficient processing platform and advanced embedded software. By combining Renesas’ high-performance image processing, low power automotive R-Car system-on-chip (SoC) with Dibotics’ 3D simultaneous localisation and mapping (SLAM) technology, the companies deliver a SLAM on Chip™.

The SLAM on Chip implements 3D SLAM processing on a SoC, a function that used to require a high-performance PC. It also realises 3D mapping with LiDAR data only, eliminating the need to use inertial measurement units and global positioning system data. The collaboration enables a real-time 3D mapping system with low power consumption and high-level functional safety in automotive systems.

As the automotive market prepares for the autonomous driving era, optimising the sensor technology required for autonomous vehicles, including real-time, high-definition perception of the environment, precise localisation of the vehicle, and real-time sensor fusion, remains a significant challenge.

LiDAR has become a key sensor, providing higher-precision obstacle sensing around the vehicle and real-time electric control unit management for vehicle control – compared with alternative methods such as cameras and radars. The rapid increase in the amount of data delivered by new LiDAR sensor technologies is driving a growing need for high-performance real-time processing of all this data.

Said Jean-Francois Chouteau, vice president, Global ADAS Centre, Renesas Electronics Corporation: “For autonomous driving … we are excited to announce our collaboration with Dibotics, who is delivering game-changing technology for the LiDAR market.”

“LiDAR sensors will play a crucial role for all ADAS [advanced driver assistance systems] and automated driving functions,” said Raul Bravo, CEO and co-founder of Dibotics. “This co-operation … [will] deliver cutting-edge performance and enable OEMs, Tier 1 suppliers and LiDAR manufacturers to reduce development cost and accelerate time-to-market.”

Unlike existing approaches, Dibotics’ Augmented LiDAR™ software realises 3D SLAM technology that only requires data from the LiDAR sensor to achieve 3D mapping. It does not require additional input from IMUs, GPS, or wheel encoders, which eliminates extra integration efforts, lowers bill-of-material (BOM) costs and simplifies development. In addition, the software realises point-wise classification, detection and tracking of shape, speed, and trajectory of moving objects, and multi-LiDAR fusion.

The high-performance capabilities of the R-Car SoC enables it to run Dibotics' Augmented LiDAR software. The R-Car has low power consumption and also meets the ISO 26262 (ASIL) FuSa standard for high functional safety. Renesas R-Car is part of the ground-breaking Renesas autonomy™ Platform for ADAS and automated driving that delivers total end-to-end solutions scaling from cloud to sensing and vehicle control.

Dibotics will demonstrate the Augmented LiDAR solution during CES 2018, to be held January 9th to 12th, 2018 in Las Vegas.
