Using an Uncrewed Surface Vehicle to Create a Volumetric Model of Non-Navigable Rivers and Other Shallow Bodies of Water

no code implementations19 Sep 2023 Jayesh Tripathi, Robin Murphy

Non-navigable rivers and retention ponds play important roles in buffering communities from flooding, yet emergency planners often have no data as to the volume of water that they can carry before flooding the surrounding.

Improving Drone Imagery For Computer Vision/Machine Learning in Wilderness Search and Rescue

1 code implementation5 Sep 2023 Robin Murphy, Thomas Manzini

This paper describes gaps in acquisition of drone imagery that impair the use with computer vision/machine learning (CV/ML) models and makes five recommendations to maximize image suitability for CV/ML post-processing.

Open Problems in Computer Vision for Wilderness SAR and The Search for Patricia Wu-Murad

2 code implementations26 Jul 2023 Thomas Manzini, Robin Murphy

This paper details the challenges in applying two computer vision systems, an EfficientDET supervised learning model and the unsupervised RX spectral classifier, to 98. 9 GB of drone imagery from the Wu-Murad wilderness search and rescue (WSAR) effort in Japan and identifies 3 directions for future research.

Explicit-risk-aware Path Planning with Reward Maximization

no code implementations7 Mar 2019 Xuesu Xiao, Jan Dufek, Robin Murphy

Without manual assignment of the negative impact to the planner caused by risk, this planner takes in a pre-established viewpoint quality map and plans target location and path leading to it simultaneously, in order to maximize overall reward along the entire path while minimizing risk.

Visual Servoing of Unmanned Surface Vehicle from Small Tethered Unmanned Aerial Vehicle

1 code implementation9 Oct 2017 Haresh Karnan, Aritra Biswas, Pranav Vaidik Dhulipala, Jan Dufek, Robin Murphy

The motor schema proposed, uses the USVs coordinates from the visual localization subsystem to control the UAVs camera movements and track the USV with minimal camera movements such that the USV is always in the cameras field of view.
