Night-Time GPS-Denied Navigation and Situational Understanding Using Vision-Enhanced Low-Light Imager

Han-Pang Chiu, Supun Samarasekera, Rakesh Kumar

In this presentation, we describe and demonstrate a novel vision-enhanced low-light imager system to provide GPS-denied navigation and ML-based visual scene understanding capabilities for both day and night operations.

2d-3d reasoning and augmented reality publications March 27, 2023

Vision based Navigation using Cross-View Geo-registration for Outdoor Augmented Reality and Navigation Applications

Rakesh Kumar, Supun Samarasekera, Han-Pang Chiu

In this work, we present a new vision-based cross-view geo-localization solution matching camera images to a 2D satellite/ overhead reference image database. We present solutions for both coarse search for cold start and fine alignment for continuous refinement.

Cross-View Visual Geo-Localization for Outdoor Augmented Reality

Han-Pang Chiu, Supun Samarasekera, Rakesh Kumar

We address the problem of geo-pose estimation by cross-view matching of query ground images to a geo-referenced aerial satellite image database. Recently, neural network-based methods have shown state-of-the-art performance in cross-view matching.

On auxiliary latitudes

Charles Karney

The auxiliary latitudes are essential tools in cartography. This paper summarizes methods for converting between them with an emphasis on providing full double-precision accuracy.

Autonomous Docking Using Learning-Based Scene Segmentation in Underground Mine Environments

Han-Pang Chiu

This paper describes a vision-based autonomous docking solution that moves a coalmine shuttle car to the continuous miner in GPS-denied underground environments.

Artificial intelligence publications November 3, 2022

Sensor Control for Information Gain in Dynamic, Sparse and Partially Observed Environments

Aravind Sundaresan, Pedro Sequeira, Vidyasagar Sadhu

We present an approach for autonomous sensor control for information gathering under partially observable, dynamic and sparsely sampled environments.

Collaborative human robot autonomy publications October 23, 2022

Ranging-Aided Ground Robot Navigation Using UWB Nodes at Unknown Locations

Han-Pang Chiu, Supun Samarasekera

This paper describes a new ranging-aided navigation approach that does not require the locations of ranging radios.

Computational sensing-low-power processing publications October 14, 2022

Low-Power In-Pixel Computing with Current-Modulated Switched Capacitors

David Zhang, Gooitzen van der Wal, Michael A. Isnardi, Michael Piacentino

We present a scalable in-pixel processing architecture that can reduce the data throughput by 10X and consume less than 30 mW per megapixel at the imager frontend.

Unpacking Large Language Models with Conceptual Consistency

SRI International

We propose conceptual consistency to measure a LLM’s understanding of relevant concepts. This novel metric measures how well a model can be characterized by finding out how consistent its responses to queries about conceptually relevant background knowledge are.
