Feature-based visual simultaneous localization and mapping: a survey

WebDuring long-term operation graph-based SLAM methods suffer from unbounded growth of the pose graph and computational cost. To limit the graph size, various methods to reduce the graph have been studied in the past. In this paper we propose a criterion to reject poses, based on the difference between expected and real scan of the candidate. The … WebLandmark detection can also be combined with graph-based optimization, achieving flexibility in SLAM implementation. Monocular SLAM is when vSLAM uses a single camera as the only sensor, which makes it challenging to define depth.
