• Future trajectory and Motion guidance with Augmented reality

  Controlling pedestrian motion pattern using augmented reality would require explainable visualizations to convince the user to change directions and speed of motion. Such AR visualizations should avoid cognitive overload and should provide motion guidance that are accurate representations of expected user actions to avoid conflicts / collisions. The focus of this master thesis would be to design and evaluate 3D motion guidance augmentations using AR emphasizing how such visualizations can avoid collisions between pedestrian / smartphone zombie. The student is expected to design and validate motion guidance visualizations in augmented reality

• Hololens 2 - Analysis of capabilities and quality

  The Hololens is a device, which captures information of the environment and creates a 3D model of it. At the same time, it is able to place virtual objects into the environment and thus allows AR-applications. The goal of the thesis is to investigate the potential of the Hololens for capturing indoor environments. This includes the acquisition of 3D point clouds and a thorough quality assessment. Subsequently, the point could has to be processed in order to segment important objects or features (e.g. walls, furniture). To this end, the use of Deep Learning models has to be considered.

• Hololens 2 – Evaluating 3D Mapping and Technical Capabilities

  In this study, the technical and 3D mapping capabilities of Hololens 2 was evaluated. The Microsoft Hololens 2 is a head-worn mobile mixed reality device that is capable of mapping its direct environment in real time. It is equipped with different sensors including four visible light tracking cameras and a depth sensor. The 3D map created using these sensor streams can be accessed by research mode. This makes Hololens 2 a powerful tool for mapping an indoor space. In this work, we evaluate the capabilities of Hololens 2 with respect to the task of the 3D indoor mapping, semantic segmentation and 3D modelling as the quality of scanned data highly influences the accuracy of reconstruction and segmentation.

• Range and FoV Estimation of Pedestrian Detection in a Helmet Mapping System

  While LIDAR based mobile mapping systems have been used to map the indoor spaces to create indoor maps, such LIDAR based systems can also be used observe motion information while mapping the environment. This motion information can be used to understand the footfall and useful to businesses and also civil engineers for better planning. The objective of the work would be to achieve a Helmet mounted mapping system (HMS) using a Velodyne and IMU and its range estimation in detecting dynamic pedestrians. The HMS is an apparatus consisting the Velodyne and IMU mounted on an industry grade Helmet. Two kinds of existing learning methods, the Complex-YOLO with optimized parameters and PointPillars are applied by training a low-resolution simulated KITTI dataset.

• Spatiotemporal Calibration between a Helmet Mapping System and the HoloLens Augmented Reality System

  Mobile mapping systems are used to map indoor environments by utilising LIDAR sensors. These sensors when worn with a helmet via the Helmet mapping system (HMS) can also be integrated with Augmented reality (AR) devices like the HoloLens 2. Such integration can be beneficial for real-time 3D visualisation of sensor data. To achieve an integrated system, the HMS and AR device needs to be precisely time synchronized matching the different sensors rates running on different operating systems. The objective of this thesis is to achieve time synchronization and rigid body transformation between a helmet-mounted mapping systems (HMS) equipped with an Xsens IMU module and an Augmented Reality (AR) system HoloLens 2. Pedestrian motion was tested to find patterns for data synchronization using human movement only.
