Indoor localisation and location tracking in semi-public buildings based on LiDAR point clouds and images of the ceilings

Nowadays, the evolution of localisation and navigation technologies is vast, aiding towards facilitating users’ guidance in various environments. Outdoor positioning can be easily achieved, with the widely used Global Navigation Satellite Systems (GNSS), which comprise a universal standard for positioning and are included in every person’s...

Utilising Deep Learning Models for the Surface Registration Problem in HoloNav

Surface Registration is a registration problem that handles the registration of two similar surfaces. In most research that utilises Deep Learning (DL) models to handle surface registration two theories are investigated; the first being whether surfaces sampled from the same origin can be registered together, and the second theory being whether...

Performing patient alignment utilizing point-cloud surface registration techniques in HoloNav

In order to be able to use the Microsoft HoloLens for surgical navigation purposes, performing good patient alignment is of utmost importance. This paper will discuss how this patient alignment can be done using different point cloud registration algorithms.<br/>A lot of research is being conducted on point cloud registration algorithms. However...

Indoor Positioning using Augmented Reality

Unlike outdoor environments, there is no wide-spread solution to positioning inside a building. Indoorsolutions rely on pre-installation of infrastructure, such as Bluetooth beacons or ultra-wide bandtechnology. Recently, there has been growing interest in the use of Augmented Reality (AR) for indoorpositioning. AR devices use an algorithm known...

Multi-Camera Registration for VR: A flexible, feature-based approach

Real-time point cloud capturing and multiple depth camera 3D reconstruction are vital elements that bring real-time representations into a virtual world and provide an im- mersive experience which can be applied to develop VR/AR applications. To make this possible, camera calibration plays an essential role in providing important camera spa-...
