Autonomous quadrotor unmanned aerial vehicle for culvert inspection
… the Global Positioning System (GPS) available outdoors to make up for the relative scarcity of objects visible to the Light Detection And Ranging sensor (LIDAR). The GPS data is fused in a new state estimator, which also incorporates data from the scan matcher running on the LIDAR data, as well …

A 3-dimensional tangible mapping and data visualization interface for MIT campus
… events, shuttle times, directions for indoor and outdoor navigation on campus, and various live social feeds, ranging from Twitter to the beloved free-food mailing list. Users can also send much of this information to their mobile device by scanning a QR code. The main contribution of this …

Transformation of digital building models from boundary representation to tetrahedral space partitioning
… building performance simulations, and indoor and outdoor navigation. The aim is to establish a foundation for various use cases that rely on separate digital model transformation algorithms. The thesis begins by reviewing the limitations of existing geometric modeling techniques in digital …

Multi-Objective Generation of Pareto-Optimal Perception Architectures for Autonomous Robotic Systems
… in this problem. Two case studies, long-range outdoor navigation on a Clearpath Jackal and short-range indoor navigation on ANYmal-C, demonstrate the framework’s ability to generate Pareto-optimal sensor architectures under vastly different ROI definitions and operating conditions. In the …

Pushing the limits of wireless networks
… and industry. While GPS has revolutionized outdoor navigation, it does not work indoors. Past work that has explored this problem is either limited in accuracy with errors of several meters, or advocates complete overhaul of the infrastructure with massive antenna-array access points that do …

Floor Plan Based Indoor Vision Navigation Using Smart Device
… almost every smart phone and tablet. Therefore, navigation using those intelligent gadgets becomes a must-have function. GPS has been widely employed for outdoor navigation, while its performance suffers from severe degradation in challenging scenarios such as urban canyon and indoor. Due to the …

GPS-LiDAR sensor fusion aided by 3D city models for UAVs
Recently, there has been an increase in outdoor applications for small-scale Unmanned Aerial Vehicles (UAVs), such as 3D modelling, filming, surveillance, and search and rescue. To perform these tasks safely and reliably, a continuous and accurate estimate of the UAVs’ positions is needed. Global …
