Three-dimensional visualization of worker positions on indoor construction space for digital twin

Abstract

In the urban space, projects are underway to link real and cyber spaces with the aim of creating a digital twin. However, there are few efforts to accumulate data for digital twin in the construction field. In this study, with the aim of constructing a construction space digital twin, we aimed to grasp the position coordinates of workers in a three-dimensional space and visualize them in three dimensions, targeting workers’ position information that has been visualized in two dimensions so far. We used three beacons to estimate the worker’s position coordinates and constructed a system to display them in the three-dimensional point cloud data. Experiments conducted in a simulated indoor construction environment verified the functionality of the proposed method, and showed that the three beacons can perform positioning and visualization in a three-dimensional space.
