Feature Tracks are not Zero-Mean Gaussian

no code implementations25 Mar 2023 Stephanie Tsuei, Wenjie Mo, Stefano Soatto

In state estimation algorithms that use feature tracks as input, it is customary to assume that the errors in feature track positions are zero-mean Gaussian.

SABER: Data-Driven Motion Planner for Autonomously Navigating Heterogeneous Robots

1 code implementation3 Aug 2021 Alexander Schperberg, Stephanie Tsuei, Stefano Soatto, Dennis Hong

We present an end-to-end online motion planning framework that uses a data-driven approach to navigate a heterogeneous robot team towards a global goal while avoiding obstacles in uncertain environments.

Risk-Averse MPC via Visual-Inertial Input and Recurrent Networks for Online Collision Avoidance

no code implementations28 Jul 2020 Alexander Schperberg, Kenny Chen, Stephanie Tsuei, Michael Jewett, Joshua Hooks, Stefano Soatto, Ankur Mehta, Dennis Hong

In this paper, we propose an online path planning architecture that extends the model predictive control (MPC) formulation to consider future location uncertainties for safer navigation through cluttered environments.

Unsupervised Depth Completion from Visual Inertial Odometry

2 code implementations15 May 2019 Alex Wong, Xiaohan Fei, Stephanie Tsuei, Stefano Soatto

Our method first constructs a piecewise planar scaffolding of the scene, and then uses it to infer dense depth using the image along with the sparse points.
