ZAHA: Introducing the Level of Facade Generalization and the Large-Scale Point Cloud Facade Semantic Segmentation Benchmark Dataset
Olaf Wysocki, Yue Tan, Thomas Froech +5
Facade semantic segmentation is a long-standing challenge in photogrammetry and computer vision. Although the last decades have witnessed the influx of facade segmentation methods,…
Enriching thermal point clouds of buildings using semantic 3D building models
Jingwei Zhu, Olaf Wysocki, Christoph Holst +1
Thermal point clouds integrate thermal radiation and laser point clouds effectively. However, the semantic information for the interpretation of building thermal point clouds can h…
Analyzing the impact of semantic LoD3 building models on image-based vehicle localization
Antonia Bieringer, Olaf Wysocki, Sebastian Tuttas +2
Numerous navigation applications rely on data from global navigation satellite systems (GNSS), even though their accuracy is compromised in urban areas, posing a significant challe…
Transferring facade labels between point clouds with semantic octrees while considering change detection
Sophia Schwarz, Tanja Pilz, Olaf Wysocki +2
Point clouds and high-resolution 3D data have become increasingly important in various fields, including surveying, construction, and virtual reality. However, simply having this d…
Reconstructing facade details using MLS point clouds and Bag-of-Words approach
Thomas Froech, Olaf Wysocki, Ludwig Hoegner +1
In the reconstruction of façade elements, the identification of specific object types remains challenging and is often circumvented by rectangularity assumptions or the use of boun…
Classifying point clouds at the facade-level using geometric features and deep learning networks
Yue Tan, Olaf Wysocki, Ludwig Hoegner +1
3D building models with facade details are playing an important role in many applications now. Classifying point clouds at facade-level is key to create such digital replicas of th…
MLS2LoD3: Refining low LoDs building models with MLS point clouds to reconstruct semantic LoD3 building models
Olaf Wysocki, Ludwig Hoegner, Uwe Stilla
Although highly-detailed LoD3 building models reveal great potential in various applications, they have yet to be available. The primary challenges in creating such models concern…
