NVIDIA DRIVE™ PX

AUTO-PILOT CAR COMPUTER

The DRIVE PX platform is based on the NVIDIA® Tegra® X1 processor, enabling smarter, more sophisticated advanced driver assistance systems (ADAS) and paving the way for the autonomous car. Tegra X1 delivers an astonishing 1.3 gigapixels/second throughput – enough to handle 12 two-Megapixel cameras at frame rates up to 60 fps for some cameras. It is equipped with 10 GB of DRAM memory and combines surround Computer Vision (CV) technology, extensive deep learning training, and over-the-air updates to transform how cars see, think, and learn.

DEEP LEARNING COMPUTER VISION

Conventional ADAS technology today can detect some objects, do basic classification, alert the driver, and in some cases, stop the vehicle. DRIVE PX takes this to the next level with the ability to differentiate an ambulance from a delivery truck or a parked car from one about to pull into traffic. The system can now inform the driver, not just get their attention with a warning. The car is not just sensing, but interpreting what is taking place around it—an essential capability for auto-piloted driving.

SURROUND VISION WITH ADVANCED RENDERING

Conventional surround view systems show the driver a virtual view of the area around the car, but often have poor image quality due to warping effects from the fisheye camera lenses. DRIVE PX uses sophisticated SFM and advanced stitching for better image rendering and reduced “ghosting”, such as where a line on the pavement can appear in two places at once. Powerful graphics enable DRIVE PX to render a virtual car in the view with high-detail models and realistic lighting effects, so you see what looks like your car, rather than a generic or toy model.

SELF-PARKING CAPABILITIES

For a car to park itself, it needs to build a 3D map of nearby objects in real time. DRIVE PX delivers the massive processing power to enable techniques like structure-from-motion (SFM) and simultaneous localization and mapping (SLAM) from four surround-view cameras that cover the immediate area around the car. Additional cameras allow for greater distance coverage in forward and cross-traffic viewpoints.

THE POWER OF THE TEGRA X1 PROCESSOR

NVIDIA DRIVE PX is powered by dual Tegra X1 processors for exceptional performance and safety. Each Tegra X1 is capable of one Teraflop of processing power and includes a powerful, energy-efficient GPU, a quad-core ARM® v8 CPU, and dedicated audio, video, and image processors. For camera processing, Tegra X1 delivers an astonishing 1.3 gigapixels/second throughput – enough to handle 12 two-Megapixel cameras at frame rates up to 60 fps for some cameras. The Tegra X1 processor also supports NVIDIA CUDA, bringing breakthrough supercomputing and deep learning processing to cars.
