A Study on Generation of 3D Model and Mesh Image of Excavation Work Using UAV

Recently, advanced and semi-automated equipment is used for earthwork project. For automated and intelligent earthwork management, surveying method needs to be improved and updated to acquire and store on-site information. Unmanned Aerial Vehicles (UAVs) was considered as an important technology and using UAVs in various areas are prominent area in recent times. Unmanned Aerial vehicles (UAVs), aerial movable image sensing platform, have become the area that has been becoming notable in all industries. Miniature UAVs can measure the imagery taken form aerial and detect environment data. This study aims to determine the optimal algorithm based on meshed surface from arbitrary imagery acquired by UAVs and generate 3D model for analyzing and getting earthwork on site. The research methodology for the proposed article focuses on: 1. Research *Comparison and analysis on related research developments on UAVs technologies *Set a target performance (criteria performance) of this research *The selection and verification of optimal aerial movable image sensing platform 2.Development of optimal algorithm and derivation of object extraction process *Obtaining information of on-site imagery and establishing the process of defining the surface mesh *Development of technology of collecting object information 3.Verification *Indoor Testing - Pilot test, the Verification for reliability and performance *Outdoor Testing -- the establishment of field test plan (earthwork project), the Verification for reliability and performanceIn this study, we proposed the optimal algorithm applied to image processing and the process for extracting object information based on imagery information acquired by UAVs for earthwork. These can generate soil surface information more accurately and help project manager get the information of real-time field more easily and will be considered as an increasingly new technology and expected to bring a tremendous ripple effect focused on availability.
