SUSTAINABLE STORMWATER URBAN MANAGEMENT TOWARDS ACHIEVING THE NEW URBAN AGENDA FOR SUSTAINABLE DEVELOPMENT
Authors:Silke Wieprecht Organization:IAHR
In experimental research, photogrammetric methods have been successfully used for high-resolution topo-graphic surveys. This study investigates the performance of the fully automated photogrammetric method Structure from Motion with Multi-View-Stereo (SfM-MVS) for sediment surfaces using dry and submerged image acquisitions. To evaluate the quality of the obtained SfM digital elevation models (DEMs), the DEMs were compared with data from laser profiling and stereo-photogrammetry. The results showed that the quality of submerged image acquisition is sufficient to generate highly detailed DEMs of sediment surfaces. Comparing dry and submerged image acquisition yielded a mean absolute deviation of <1.0 mm. In conclusion, the achievable accuracy of topographical measurements for sediment surfaces demonstrated the high potential of SfM-MVS for many applications in hydraulic laboratories
