Performance Verification of Integrated Module for Automatic Analysis of Digital Maps in Earthwork Sites

Abstract

Research on digitalization of construction sites using UAV (Unmanned Aerial Vehicles), UGV (Unmanned Ground Vehicles), and three-dimensional scanners is rapidly progressing. However, most 3D digital map generation and analysis technologies are still performed individually by utilizing libraries and software that require human intervention. In this study, we developed a digital map automatic analysis framework by reviewing five algorithms required for digital map generation and analysis for 3D digital map generation and analysis automation, defining the optimal forward and backward relationship between algorithms. In addition, based on the developed framework, the "digital map automatic analysis integrated module" is developed by considering the scan data format conversion and data processing process for automation. Furthermore, the effectiveness of the development module was verified by automating and speed testing the developed "digital map automatic analysis integrated module".
