Evolving MMS from 3D Measurement of Road Area to Facility Inspection—Diagnosing Wear in Millimeters and Deterioration in Terms of Rust, Stains, and Cracks

摘要

A mobile mapping system (MMS) measures surrounding structures (including roads) in three dimensions and creates a database based on the obtained information. Measurement equipment mounted on a vehicle mainly consists of devices for measuring the position of the vehicle and measuring around the vehicle three-dimensionally (laser devices are the mainstream). Efforts by NTT Infrastructure Network Corporation (NTT InfraNet) to address issues concerning an MMS are introduced in this article.
