Dense RGB-D-Inertial SLAM with Map Deformations
Tristan Laidlow, Michael Bloesch, Wenbin Li +1
While dense visual SLAM methods are capable of estimating dense reconstructions of the environment, they suffer from a lack of robustness in their tracking step, especially when th…
Simultaneous Localisation and Mapping with Quadric Surfaces
Tristan Laidlow, Andrew J. Davison
There are many possibilities for how to represent the map in simultaneous localisation and mapping (SLAM). While sparse, keypoint-based SLAM systems have achieved impressive levels…
Coarse-to-Fine Q-attention: Efficient Learning for Visual Robotic Manipulation via Discretisation
Stephen James, Kentaro Wada, Tristan Laidlow +1
We present a coarse-to-fine discretisation method that enables the use of discrete reinforcement learning approaches in place of unstable and data-inefficient actor-critic methods…
A Primer on the Differential Calculus of 3D Orientations
Michael Bloesch, Hannes Sommer, Tristan Laidlow +8
The proper handling of 3D orientations is a central element in many optimization problems in engineering. Unfortunately many researchers and engineers struggle with the formulation…
