As world urbanization continues apace and total population increases, there is an immediate demand for better monitoring and exploitation of space. In view of the above, the “Smart Cities” concept has been developed and numerous efforts are made to deploy technology to this end. The main information needed for city development and planning is...

Indoor environments can be complex and need to be represented by a 3D representation. This is especially important for 3D path-finding. 3D features of the environment can have an effect on the computed path and these features can not be represented correctly in a 2D representation. A voxelized model is a good 3D representation that supports path...

This thesis presents a new workflow for path finding through an octree representation of an indoor point cloud. I applied the following steps: 1) the point cloud is processed so it fits best in an octree; 2) during the octree generation the interior empty nodes are identified and further processed; 3) for each interior empty node the distance to...

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...

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...

Nowadays, construction projects are considered to be risky mainly because of to their high complexity and the various uncertainties which they include. Geotechnical risks due to unknown subsoil conditions or variation of groundwater tables as well as their causes and failures, are a significant source of project risks. On the contrary, effective...

Indoor positioning is becoming a hot topic in public areas that are used by large numbers of people. Finding people and assets in buildings has become more difficult because of the complexity and scale of today’s public space. On the subject of locating assets in the hospital the following use case is defined for this project. Positioning and...

Fugro GeoServices is currently storing their CAD models of the Petrochemical Industry as attributes of 2D lines in a spatial DBMS. This solution works well for web visualization, but not for performing analyses in 3D. The main objective of this graduation project is to create a 3D spatial DBMS with solid CAD geometries as input. The difficulty...

This thesis focusses on the intersection 3D Boolean set operation on voxel data represented as surfaces, with other 3D surface based vector data, in GIS. The Application of this research makes the linkage with geohydrology possible: based on the vectorised GeoTOP (TNO) data the water infiltration and storage capacity of specific locations can be...

All existing data sources used to reconstruct 3D building models have certain restrictions. An eye-catching alternative is IndoorOSM, one of the most popular examples of the newly evolved crowdsourced geodata. The potential power of this rich and simple-formatted data source has been proven by many researches. However, a fatal flaw of IndoorOSM...

Nowadays, not all pedestrian paths are accessible for mobility impaired people. Especially paths which consist of complex public spaces and old streets constitute problems. However, no reliable information is (quickly) available about problems that cause hindrance. The sensing rollator called meet rollator is equipped with several sensors that...

Point clouds can be obtained by airborne or terrestrial Light Detection and Ranging (LiDAR) scanning or directly from street-view panoramic imagery. Point clouds obtained from airborne scanners cover most roof information but lack facade information. Similar but orthogonal to airborne scanning, street-view point clouds cover well of the facade...

Facade reconstruction from terrestrial LiDAR point cloud is affected by both quality of point cloud itself and imperfectness of object recognition algorithms. In the facade, there are many features, which are shared within an object or among objects. For example, within one window, the boundaries of it may share parallel and orthogonal...

The aim of the research was to develop conceptual model for determination of functional areas with abstract borders within indoor space and to illustrate how determined functional areas can be applied to facilitate wayfinding process in indoor environments. The objectives of the research were to define criteria for determination of functional...

The past seventy years the number of disasters that occur, man-made and natural, has increased. This problem requires suitable and efficient means to control and respond to emergency situations. Currently, the emergency responders use maps and software that allows for two dimensional visualisations of situations. Meanwhile the development of...

Where Level of Detail (LoD) allow City Geography Markup Language (CityGML) models to be shared over different application domains, only one LoD defines building interiors. As there are potentially numerous applications with a need for building interiors (but not with all the details as defined in LoD4), in order to attain a larger applicability...

With laser scanning (including laser altimetry and multi-beam echo sounding), many data points, called point clouds, are measured. The interest in point clouds is increasing. Depending on the laser scanner, the measurement set-up and the technique, the number of points in one dataset can vary from a few hundred points to over a billion points....

This research discusses the conversion of underground utilities datasets into scene graph models for its 3D visualization using the WebGL technology, which is a Javascript interface to access the 3D graphics hardware. This conversion requires to reconstruct the volumetric appearance of the objects from its abstract representation, involving...

The notion of terroir covers the interaction between the natural, the cultural conditions and the grape vine itself relative to the character of the final wine product. It is about a dynamic chain whose factors get different weights in each wine region and this results in the typicality of the different terroir wine products. The Old World wine...
