Facility survey by handheld laser scanner using SLAM algorithm －A case study at THE MUSEUM MEIJI-MURA－

Abstract

Efficient survey method is necessary around many kinds of facilities in these days including indoor environment where GNSS for precise and convenient survey is not available. In this case we present the survey example of modern architectural heritage “THE MUSEUM MEIJI-MURA”with handheld laser scanner “Zeb1” using SLAM algorithm. We captured precise point cloud easily and at low cost. After adequate visualization the point cloud easily became 3D floor maps as well as floor plans and cross sections.
