The Use of Multi-Scale Fiducial Markers To Aid Takeoff and Landing Navigation by Rotorcraft

no code implementations15 Sep 2023 Jongwon Lee, Su Yeon Choi, Timothy Bretl

This paper quantifies the performance of visual SLAM that leverages multi-scale fiducial markers (i. e., artificial landmarks that can be detected at a wide range of distances) to show its potential for reliable takeoff and landing navigation in rotorcraft.

Comparative Study of Visual SLAM-Based Mobile Robot Localization Using Fiducial Markers

no code implementations8 Sep 2023 Jongwon Lee, Su Yeon Choi, David Hanley, Timothy Bretl

This paper presents a comparative study of three modes for mobile robot localization based on visual SLAM using fiducial markers (i. e., square-shaped artificial landmarks with a black-and-white grid pattern): SLAM, SLAM with a prior map, and localization with a prior map.

You Only Need One Model for Open-domain Question Answering

no code implementations14 Dec 2021 Haejun Lee, Akhil Kedia, Jongwon Lee, Ashwin Paranjape, Christopher D. Manning, Kyoung-Gu Woo

Recent approaches to Open-domain Question Answering refer to an external knowledge base using a retriever model, optionally rerank passages with a separate reranker model and generate an answer using another reader model.
