How High-Definition Maps Are Plotting the Course to Autonomous Cars

through the June 2016 issue

, cameras along with radar sensor devices that will can enable automatic control systems extremely Cruz today you see only 250 yards ahead from the best of circumstances. that will can be barely more than six seconds through the time limit from the 80 miles per hour, traffic, weather, terrain along with often shrinking vision for shorter distances. For true independence, along with self-driving cars will need a better understanding of the bigger picture.

like a drum, here creates a high-definition maps (above) of billions of data points captured by laser scanners (top of the page).

to create a high-resolution along with RoadDNA image maps, vans along with drawing mobile maps drum to a record 22 billion pixels per mile with the cameras on board, in while the scanner can be managed emitting laser combines more than 700,000 data points per second. Using three-dimensional data compression to the two-dimensional images, the drum can condense every highway in America to almost 20 gigabytes of data.

the next generation of so-called high-definition maps will supply the picture, along with enough detail to computers to take predictive decisions rather than amendments to the reaction. While navigation maps today represents all the way single aisle, along with include maps HD multi-lane with usage rules along with restrictions, along with shoulders, along with road signs, along with fences. Carrying high-definition maps, along with smarter cars jump slow-motion pace, along with negotiating intersections, move on to integrate the automobile, along with choose the correct lane for exit, along with knows where to stop in an emergency for all situations without driver input.

in charting a course for the Autonomous Cars, mapmakers faces major paradox: The more detailed the map, the more likely that will can be to be inaccurate. Shoulders become lanes, speed limits change, construction turns meticulously planned traffic patterns from the chaos. that will’s why here-mapping can be owned by BMW that will company, Daimler, along with Volkswagen Group-imagine the future of the vehicle autonomous redraw the maps as they travel the roads.



“We map annually regions. This kind of probably can be not fresh enough to maintain what we need to move forward, “says John Ristevski, vice president of capturing reality along with treatment here. “We need to reflect any improvements from the environment in real time.” Dynamic Here HD aggregates Maps layer live data through sensors fixed, government agencies, along with some other cars on the road to adapt to the lane temporary closure, accidents, traffic jams, along with the permanent improvements to traffic patterns.

for mapmakers, can be the way forward along using a clear sign of the obstacles placed. Here Ristevski can be supposed to be the most advanced cars will pay the entrance-exit on the highway without the driver’s intervention or supervision within three to a few years.

along with even more detailed map useless if you do not know your site. Consumer-grade GPS can only put the automobile inside a circle 10 feet, so mapmakers methods have been developed to determine the exact position on the maps HD them, a process known as localization.

strengthens the drum for high-definition maps with RoadDNA, which compares live data captured by the sensor to be administered on board with images recorded by mapping vehicles. By identifying patterns from the images along with nuances between the sites of fixed landmarks, RoadDNA can locate the vehicle position along on the road to within six inches. In a typical hot at the level of 138 inches, This kind of can be accurate enough to allow steering the automobile. “Drift along with six inches in one direction or the some other can be something that will most of us can hardly imagine, even if we are driving down the road ourselves,” says Nhai Cao, director of global product along with drum. However, no one can be suggesting the exclusion lane keeping systems based on camera today. Well, not yet.
