Straightening and simplifying a multi-view stereo mesh of a city

With fast development of both hardware and software, 3D real-world scene<br/>data, for example multi view stereo mesh, can be acquired efficiently. And<br/>since 3D city data are more realistic and more useful in some applications,<br/>they begin to appear in the market.<br/>Although the generation of 3D city data like multi view stereo mesh<br/...

Automatic thematic and semantic classification of 3D city models

Developments in remote sensing created new possibilities to capture the human environment on a large scale. This data is used in the generation of large scale Three dimensional (3D) city models, which has led to a higher demand for 3D city models in a wide range of fields. The lack of semantic information in many 3D city models is a considerable...

Semantic enrichment of a point cloud based on an octree for multi-storey pathfinding

Acquiring point clouds of indoor environments became increasingly accessible in recent years. However, the resulting 3D point cloud data is unstructured, and does not contain enough information to be useful for complex tasks like pathfinding. Indoor models which are currently derived from point clouds do not include furniture and stairs. The...

Navigation to a human in motion by using points of interest

Navigating to a human target is underexposed in the current literature. However, there are cases where it is necessary to get to the moving target as fast as possible. This thesis supports navigation of a person to another person in motion that they lost or need. In this way, children, elderly, family, coworkers and friends could be found more...
