WebA Semantic-Based Loop Closure Detection of 3D Point Cloud Pages 1184–1189 ABSTRACT Compared with loop closure detection based on vision, loop closure detection based on 3D point cloud is more robust against the changes in the external environment, and therefore has attracted more and more research interests. WebII. POSE GRAPH SLAM A. Problem Formulation In the state of the art formulation of pose graph SLAM, we are given a set of odometry constraints u i between two successive poses x i and x i+1, so that x i+1 = f(x i;u i) + w i (1) Furthermore, the front-end part of the system can detect loop closures between two poses x i and x j, for example by landhotel berggasthof panorama
