A Study on a 3D Spatial Mapping System to Investigate Skyscrapers Using Drones

Recently, as the drone industry develops, related technologies are being used in various fields. In particular, drone technology is being used to search for missing people with large-scale manpower, detect cracks and rust in high-rise buildings, and perform safety inspections. However, there was a downside to using existing drones. First, after shooting the target, check the abnormal point in the original video with the naked eye and save it to the local memory as a file. Also, during AI analysis, it was processed as a cumbersome procedure in which batch-type files had to be analyzed in the analysis module and then the results had to be checked again. Accordingly, this paper proposes a method of visualizing 4K (3840X2160) still images transmitted from drones in real time and AI analysis in real time, and then visualizing the resulting data on a 3D web map.
