Japan started to develop high-precision 3D-maps for the self-car

Cars that can drive on their own without a driver, developed in many countries around the world, testing is in full swing, and some companies involved in the development of such technology, already being tested first working prototypes. Japan has not remained aloof from fashion trends, so in Japan is also testing such vehicles. A good occasion to showcase their developments in this area – the summer Olympics, which will be held in Tokyo, very soon, in 2020.

To drones could efficiently and safely carry passengers, they need to provide good three-dimensional map, the development of which is currently occupied by a joint venture established by Mitsubishi Electric, Zenrin card manufacturer and nine car manufacturers interested in promoting their innovative developments like in the field of unmanned vehicles, as in a conventional automobile.

Soon it planned to create three-dimensional maps of the main high-speed roads in the country. In the first phase will make a three-dimensional map that covers about 300 kilometers of main highways, and then, probably, the company will be engaged in study of secondary roads, highways and city streets. To create a card using special vehicles, equipped with special equipment. The collected data is processed, systematize and provide ready-made car manufacturers who have invested in the development.

For the unmanned vehicle to have an accurate idea of its location is very important, so the three-dimensional map will be carefully recreate not only the roadway but also its surroundings, including road signs, signs, construction, located on the roadsides. With the help of this card will be able to advance self-propelled cars to slow down when turning at the intersection with traffic lights, so you can avoid an accident or congestion.

Despite the special sensors and a camera, which is equipped vehicles, as well as special road mark to help autonomous vehicles, errors in recognizing objects still represent a serious problem for other road users. Far from perfect and modern navigation systems, whose cards are often too sketchy to unmanned machine could make safe passage route, focusing on them. Therefore, the combination of high-resolution three-dimensional maps, sensors and GPS-modules allow the car to be more precise and better position themselves on the road, being guided in the location of traffic lights, roundabouts and intersections.
