A continuous approach to information-theoretic exploration with range sensors
… gain -- i.e. mutual information -- between an occupancy map and a range sensor measurement. The algorithm we derive has a lower complexity and in practice runs 200 to 1500 times faster than the state of the art CSQMI and FSMI algorithms. The speedup is due to the realization that the mutual …

GridSLAM on the RAPTOR autonomous vehicle
… a particle filter to generate a discretized 2D occupancy map. This GridSLAM implementation uses sparse, shared, and lazy data structures to reduce memory usage and computation requirements.

Deep learning-based artifacts removal in video compression
… each represented by its texture, depth, and occupancy map for reconstruction. To deal with oc- clusion, each patch is projected onto near and far depth fields in the geometry video. Once there are artifacts on the compressed two-dimensional (2-D) geometry video, they would be propagated to …

Robotic Inspection and Data Analytics to Localize and Visualize the Structural Defects of Civil Infrastructure
… without preprocessing, generating a volumetric occupancy map of subsurface objects; and 4) the development of visual inspection software for civil engineers to visualize, label, and measure surface defects from collected RGB and Depth images.</p> <p>This thesis reviews various solutions proposed …

Adaptation in Non-Parametric State Estimation with Application to People Tracking
… for which we propose a locus-based probabilistic occupancy map (LPOM). The LPOM computes the probability of targets being in the map by using only motion information plus calibration data. To make the tracking system more scalable, we present a decentralized multi-camera multi-people tracking …

Experiments in Real-time Path Planning for Riverine Environments
… route is proposed based on an a priori shoreline map. Then, local paths are calculated considering both the a priori data and measurements received from an obstacle sensor. These paths roughly follow the global path. The algorithm was tested on an ASV equipped with basic navigational sensors and …

Implementation Of Path Planning Methods To Detect And Avoid GPS Signal Degradation In Urban Environments
<p>In the modern world, various missions are being carried out under the assistance of autonomous flight vehicles due to their ability to operate in a wide range of flight conditions. Regardless, these autonomous vehicles are prone to GPS signal loss in urban environments due to obstructions that …
