Location cloud company, HERE, has mapped London in preparation for autonomous cars, as manufacturers plan to start trialling driverless vehicles on public roads as early as 2017. The company has used LiDAR (Light Detection and Ranging) technology to provide comprehensive data that can be used by driverless cars to understand the world around them.
HERE has been collecting raw data for a number of years with its fleet of “HERE True” collection vehicles. The company is able to record 700,000 3D data sections per second, allowing it to pinpoint curbs, trees and road furniture to a 10cm accuracy. This data is then transposed onto a highly detailed, dynamic representation of the road, called HERE HD Live Map.
HERE HD Live Map creates a highly accurate, continuously updated representation of the road environment. This map is made up of three separate layers which detail precise lane geometry and boundaries; tell the vehicle about upcoming congestion, temporary road layouts and adverse weather and analyse existing driver data to provide a more human driving experience.
This kind of information is crucial to the success of Advanced Driver Assistance Systems (ADAS), such as traffic jam assist and lane keeping, which are already commercially available in ‘connected’ cars. These systems are paving the way for fully autonomous vehicles. In the future, these precise maps will be used by driverless cars to safely take you where you need to go.
