On the Coupling of Depth and Egomotion Networks for Self-Supervised Structure from Motion

1 code implementation7 Jun 2021 Brandon Wagstaff, Valentin Peretroukhin, Jonathan Kelly

Structure from motion (SfM) has recently been formulated as a self-supervised learning problem, where neural network models of depth and egomotion are learned jointly through view synthesis.

Self-Supervised Scale Recovery for Monocular Depth and Egomotion Estimation

1 code implementation8 Sep 2020 Brandon Wagstaff, Jonathan Kelly

The self-supervised loss formulation for jointly training depth and egomotion neural networks with monocular images is well studied and has demonstrated state-of-the-art accuracy.

Heteroscedastic Uncertainty for Robust Generative Latent Dynamics

1 code implementation18 Aug 2020 Oliver Limoyo, Bryan Chan, Filip Marić, Brandon Wagstaff, Rupam Mahmood, Jonathan Kelly

Learning or identifying dynamics from a sequence of high-dimensional observations is a difficult challenge in many domains, including reinforcement learning and control.

Self-Supervised Deep Pose Corrections for Robust Visual Odometry

1 code implementation27 Feb 2020 Brandon Wagstaff, Valentin Peretroukhin, Jonathan Kelly

We present a self-supervised deep pose correction (DPC) network that applies pose corrections to a visual odometry estimator to improve its accuracy.

LSTM-Based Zero-Velocity Detection for Robust Inertial Navigation

1 code implementation13 Jul 2018 Brandon Wagstaff, Jonathan Kelly

While existing threshold-based zero-velocity detectors are not robust to varying motion types, our learned model accurately detects stationary periods of the inertial measurement unit (IMU) despite changes in the motion of the user.

Improving Foot-Mounted Inertial Navigation Through Real-Time Motion Classification

1 code implementation4 Jul 2017 Brandon Wagstaff, Valentin Peretroukhin, Jonathan Kelly

We present a method to improve the accuracy of a foot-mounted, zero-velocity-aided inertial navigation system (INS) by varying estimator parameters based on a real-time classification of motion type.
