Visibility is a common measure to describe the spatial properties of an environment related to the spatial behaviour. Isovists represent the space that can be seen from one observation point, and they...
The 3D triangle mesh is widely used to represent indoor space. One of widely used methods of generating 3D triangle mesh data of indoor space is the construction from the point cloud collected using L...
Up-to-date and reliable 3D information of indoor environments is a prerequisite for many location- based services. One possibility to capture the necessary 3D data is to make use of Mobile Mapping Sys...
Efficient and comfortable acquisition of large 3D scenes is an important topic for many current and future applications like cultural heritage, web applications and 3DTV and therefore it is a h...
A combination of faster, cheaper and more accurate hardware, more sophisticated software, and greater industry acceptance have all laid the foundations for an increased desire for accurate 3D parametr...
3D models of indoor environments are important in many applications, but they usually exist only for newly constructed buildings. Automated approaches to modelling indoor environments from imagery and...
A novel high-speed optical wireless communication system incorporating WDM technology for indoor personal area networking applications is proposed and demonstrated. A 4×12.5Gbps mobile communication l...
We propose the concept of over-gigabit visible light indoor networks using λ-conversion achieved by combining a short pulse modulator with a QPM-LN module. Error free operation at 1.25 Gb/s is confirm...
We studied the cable friction and found that it depends on polymer sheath stiffness and lubricants. Optimization should prevent stick-slip motion and reduce the friction by controlling the polymer sti...
Fiber transmission of simultaneous optically generated FCC compliant 625Mbps impulse radio UWB and 80Mbps 256-QAM IEEE 802.16 WIMAX signals is experimentally demonstrated by using a single directly mo...
Link budget calculations are performed to study the potential of integrated optical phased arrays for Gb/s wireless links. A link with two integrated OPAs is feasible with a beam steering range of a f...
