Direct initial orbit determination

no code implementations28 Aug 2023 Chee-Kheng Chng, Trent Jansen-Sturgeon, Timothy Payne, Tat-Jun Chin

Initial orbit determination (IOD) is an important early step in the processing chain that makes sense of and reconciles the multiple optical observations of a resident space object.

ROSIA: Rotation-Search-Based Star Identification Algorithm

1 code implementation2 Oct 2022 Chee-Kheng Chng, Alvaro Parra Bustos, Benjamin McCarthy, Tat-Jun Chin

This paper presents a rotation-search-based approach for addressing the star identification (Star-ID) problem.

Monocular Rotational Odometry with Incremental Rotation Averaging and Loop Closure

no code implementations5 Oct 2020 Chee-Kheng Chng, Alvaro Parra, Tat-Jun Chin, Yasir Latif

To simplify the task of absolute orientation estimation, we formulate the monocular rotational odometry problem and devise a fast algorithm to accurately estimate camera orientations with 2D-2D feature matches alone.
