RISE-SLAM: A Resource-aware Inverse Schmidt Estimator for SLAM

no code implementations23 Nov 2020 Tong Ke, Kejian J. Wu, Stergios I. Roumeliotis

In this paper, we present the RISE-SLAM algorithm for performing visual-inertial simultaneous localization and mapping (SLAM), while improving estimation consistency.

Surface Normal Estimation of Tilted Images via Spatial Rectifier

1 code implementation ECCV 2020 Tien Do, Khiem Vuong, Stergios I. Roumeliotis, Hyun Soo Park

Our two main hypotheses are: (1) visual scene layout is indicative of the gravity direction; and (2) not all surfaces are equally represented by a learned estimator due to the structured distribution of the training data, thus, there exists a transformation for each tilted image that is more responsive to the learned estimator than others.

Alternating-Stereo VINS: Observability Analysis and Performance Evaluation

no code implementations CVPR 2018 Mrinal K. Paul, Stergios I. Roumeliotis

One approach to improve the accuracy and robustness of vision-aided inertial navigation systems (VINS) that employ low-cost inertial sensors, is to obtain scale information from stereoscopic vision.
