3.4 3D Visualization of Bridge Inspection Results To provide a better visualization of bridge inspection results, we proposed to develop the 3D model of BEAST to assist in the inspection process. In this study, aerial images were collected from BEAST by using a drone mounted with a high resolution HD camera. 3D reconstruction by photogrammetry was used to develop the 3D meshed model of BEAST. Figure 31 shows the developed 3D models of BEAST, and Figure 32 shows the IR condition map overlayed on the 3D model. Details of methodology can be found in Appendix V.
