Mitsubishi Electric Develops Technologies for Automated Mapping andExtraction of Transitions in Mapping Landscape for High-precision 3D
Maps Essential in Autonomous Driving
Combination of AI and proprietary Mobile Mapping System could help hasten autonomous driving
TOKYO, March 16, 2017 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it hasdeveloped technologies for automated mapping and extraction of transitions in mapping landscape based on
artificial intelligence (AI) and the company’s own Mobile Mapping System (MMS) for highly precise
three-dimensional maps that provide static information of roads and surrounding objects, intending to form
the basis for dynamic maps indispensable for autonomous driving. As a forerunner in the industry,
Mitsubishi Electric aims to contribute to the early implementation of maps that offer constantly updated
dynamic information, such as traffic signals and information about surrounding vehicles etc., for safe, highly
precise autonomous driving.
Both technologies will be exhibited for the first time at CeBIT 2017 in Hannover, Germany at the Mitsubishi
Electric booth in Hall 4, booth A38 (24) from March 20 through March 24, 2017.

Automated Mapping TechnologyThe automated mapping technology uses AI to quickly create precise, accurate three-dimensional maps.
Only necessary information, such as road markings and traffic signs, is extracted from laser-point clouds andcamera data measured and collected by MMS. Mitsubishi Electric’s MMS provides 3D positional
information of roads and roadside structures with an absolute precision within 10cm or less, which iscollected via a system consisting of laser scanners, cameras and GPS antennas, while driving. AI improves
the precision of extraction and recognition of the only data necessary, resulting in some 10 times faster map
creation compared to industry-standard manual creation. The system also costs less than conventional
methods.
Technology for Extraction of Transitions in Mapping LandscapeMitsubishi Electric is using its difference extraction technology for earlier establishment of the dynamic map
itself and more efficient updating and maintenance at a faster pace. By automatically extracting characteristic
points of past data and the latest laser-point cloud data measured with MMS, the difference extraction
technology is able to distinguish differences and changes where characteristic points do not match. Thanks tothis technology, the maintenance of dynamic maps and the updating of precise 3D maps can be accomplishedmuch faster by automatic extraction of only the points that has changed, compared to updating the entire
map each time.
Looking ahead, Mitsubishi Electric plans to sell software utilizing this automated mapping and difference
extraction technologies to map publishers including Dynamic Map Planning Corporation this coming
October. The software will be used for the creation of highly precise 3D maps of expressways in Japan.
Background
Automated driving in Japan is expected to evolve from advanced driver assistance systems (ADAS) toautomatic-driving level 3 (conditional autonomous operation) between 2019 and 2020, creating further
demand for related systems. Automatic driving systems will require combinations of in-vehicle sensors aswell as dynamic maps, of which the biggest challenges would be to keep the map information constantly up
to date. Mitsubishi Electric’s new technologies for automated-mapping and extraction of transitions inmapping landscape create and renew precise 3D maps faster and efficiently, and therefore are expected toserve as the core technologies of dynamic map creation. Going forward, the company will continue
contributing toward the early creation, maintenance and updating of dynamic maps indispensable forautonomous driving.
