| Summary: | Airborne high resolution oblique imagery systems and RPAS/UAVs are very promising technologies that will keep on influencing
the development of geomatics in the future years closing the gap between terrestrial and classical aerial acquisitions. These two
platforms are also a promising solution for National Mapping and Cartographic Agencies (NMCA) as they allow deriving
complementary mapping information. Although the interest for the registration and integration of aerial and terrestrial data is
constantly increasing, only limited work has been truly performed on this topic. Several investigations still need to be undertaken
concerning algorithms ability for automatic co-registration, accurate point cloud generation and feature extraction from multiplatform
image data. One of the biggest obstacles is the non-availability of reliable and free datasets to test and compare new
algorithms and procedures.

The Scientific Initiative “ISPRS benchmark for multi-platform photogrammetry”, run in collaboration with EuroSDR, aims at
collecting and sharing state-of-the-art multi-sensor data (oblique airborne, UAV-based and terrestrial images) over an urban area.
These datasets are used to assess different algorithms and methodologies for image orientation and dense matching. As ground truth,
Terrestrial Laser Scanning (TLS), Aerial Laser Scanning (ALS) as well as topographic networks and GNSS points were acquired to
compare 3D coordinates on check points (CPs) and evaluate cross sections and residuals on generated point cloud surfaces. In this
paper, the acquired data, the pre-processing steps, the evaluation procedures as well as some preliminary results achieved with
commercial software will be presented. |
