End-to-end Hd Mapping for Self-driving Cars

The Future of Mapping

The advanced sensors and high-performance compute that are laying the foundation for autonomous vehicles are also driving the next generation of high-definition (HD) map development. NVIDIA DRIVE Mapping is an open and scalable solution that can create, update, and localize to cloud-based maps using existing HD maps, vehicle sensor data, and the NVIDIA DRIVE platform.

Localization to Hd Maps

DRIVE Localization is a vital component to autonomous vehicle development, using the compute power of NVIDIA DRIVE Xavier and the worldwide reach of HD maps from NVIDIA DRIVE Mapping partners. Vehicles can now use mass-market sensors to position themselves on globally available HD maps with unprecedented robustness and accuracy.

Updating Existing Hd Maps

DRIVE Mapping uses the perception capabilities of vehicles on the road to help update cloud-based HD maps of NVIDIA mapping partners. NVIDIA DRIVE perception capabilities detect semantic features and new landmarks (e.g., road boundaries, lanes, signs, poles, traffic lights) in the vehicle’s environment to compare with those from the HD mapping provider. Using DRIVE MapStream, that data is uploaded to the cloud, updating the map with any new or changed features on the roadway.

Map Creation

Using a similar process to map update, DRIVE Mapping can create new maps in places where they don’t yet exist. Perception software on the NVIDIA DRIVE platform detects semantic landmarks based on sensor data from vehicles driving within the new mapping territory. This data is then fused with information from previous drives to build the HD map. These newly created personal maps are called myRoutes.

NVIDIA automotive solutions are available to automakers, tier 1 suppliers, startups, and research institutions working on the future of transportation.
