- Synopsis
- Although rebar arrangement inspection is an important part of the construction process, the preliminary preparations to be made for the series of inspection tasks, the inspection work itself, and the preparation of reports require a lot of time and effort. The authors have begun developing a rebar arrangement inspection system using stereo cameras and AI technology, and this system is currently being used at many sites. Further, the system was adopted by the Ministry of Land, Infrastructure, Transport and Tourism(MLIT) as part of the “Public/Private R&D Investment Strategic Expansion Program (PRISM),” which supports “projects related to the introduction and utilization of innovative technologies to dramatically enhance productivity at construction sites.” Trial application of this technology at actual construction sites earned it a rating of A for highly promising introduction effects and high feasibility of implementation in society. In anticipation of the further spread of this system in the future, the authors have developed heretofore unavailable functions for lower layer rebar arrangement measurement, wide area measurement, and sheath pipe measurement.
