Title: 3D mapping concept and field evaluation result of the latest Mobile Mapping System
Abstract: 

Mobile mapping systems are playing an increasingly important role in capturing spatial data, coinciding with the rapidly growing demand for detailed, up-to-date 3D maps of cities, roads and large buildings. Thus, Mobile mapping systems are widely used in Public Survey, Asset Management, and Automotive related HD map for Automated driving. 

Mitsubishi Electric’s the latest mobile mapping system called “MMS-G” is examined for its 3D mapping capability in Japanese urban area using multi GNSS including GPS, Beidou and Glonass, where satellite invisiblity and multipath is occurred according to high rise buildings. 

MMS-G is equipped with multi-GNSS dual-frequency carrier-phased receiver, high performance IMU, and high-range LIDAR in compact unit, which can be easily mounted/dis-mounted on the vehicle. 

The data from this mobile mapping system is processed automatically from positioning, IMU coupling, to coloring point cloud data from camera RGB data. Furthermore, manual processing of point clouds is labour-intensive and thus time-consuming and expensive. Thus, the state of the art of automatic classification and 3D mapping of road objects from point clouds is also described. 

In this article, the authors explain the concepts underlying the product and prove its initial design’s feasibility and its accuracy and precision through pre-measured reference points.

Biography: 

Dr.Junichi Takiguchi is a Deputy General Manager of HD Map Solution unit, Mitsubishi Electric Corporation. He has a MSc in Artificial Intelligence from Edinburgh University, UK, and a Ph. D. of Mechanical Engineering from Waseda University, Tokyo, Japan. Dr. Takiguchi oversees HD Map solution business at the company for Asia, the United States, and Europe including developing effective solutions and usages of base data of the maps together with survey, mapping companies and manufacturers. 

He joined Mitsubishi Electric in 1986 and worked for defense and satellite group as a satellite based navigation engineer. In 2003, he invented Japan’s first commercial based MMS by harnessing his expertise of positioning engineer. Up to the present, he has joined many MMS related products. From 2012, he also has worked on the Japanese Quasi-Zenith Satellite System project which provides high precision GNSS positioning services to mass market applications in Japan. 

Dr. Takiguchi is active in the academic field as well. He has engaged in fostering the future generations of positioning engineers. From 2007 to 2012, he undertook research and education in mechanical engineering of Waseda University as a visiting associate professor.
