Improving Visual Place Recognition Based Robot Navigation by Verifying Localization Estimates

RA-L 2024

Visual Place Recognition (VPR) systems often have imperfect performance, affecting the ‘integrity’ of position estimates and subsequent robot navigation decisions. Previously, SVM classifiers have been used to monitor VPR integrity. This research introduces a novel Multi-Layer Perceptron (MLP) integ

Unsupervised Quality Prediction for Improved Single-Frame and Weighted Sequential Visual Place Recognition

ICRA 2023poster

While substantial progress has been made in the absolute performance of localization and Visual Place Recognition (VPR) techniques, it is becoming increasingly clear from translating these systems into applications that other capabilities like integrity and predictability are just as important, espe…

Predicting to Improve: Integrity Measures for Assessing Visual Localization Performance

RA-L 2022

Visual Place Recognition (VPR) is a key component of many robot localization and mapping system processing pipelines, providing loop closure and coarse topological localization priors for pose refinement stages. When deploying these systems in the real-world, system self-characterization of when it
