Tracking Multiple Unmanned Aerial Vehicles on SE(3) Using a Monocular Camera
IEEE Transactions on Aerospace and Electronic Systems(2023)
摘要
This article presents MTT-
$\text{SE}\mathopen {}(3)\mathclose {}$
, a vision-based multiple-target tracking algorithm for targets that evolve on the special Euclidean group
$\text{SE}\mathopen {}(3)\mathclose {}$
in dense clutter. The target state consists of the pose in
$\text{SE}\mathopen {}(3)\mathclose {}$
and the twist of the vehicle. Contributions of the article include the development of a robust track initialization scheme designed on
$\text{SE}\mathopen {}(3)\mathclose {}\times \mathbb {R}^{6}$
, and a track-to-track association and fusion algorithm to merge similar tracks evolving on
$\text{SE}\mathopen {}(3)\mathclose {}\times \mathbb {R}^{6}$
. The performance of MTT-
$\text{SE}\mathopen {}(3)\mathclose {}$
is verified in hardware by simultaneously tracking three multirotors using a stationary monocular camera. The results are compared to a multiple-target tracking algorithm that uses linear, time-invariant nearly constant velocity, acceleration, and jerk models, where it is shown that MTT-
$\text{SE}\mathopen {}(3)\mathclose {}$
improves several traditional tracking metrics.
