Solving the MLE problem is non-trivial, especially if the number of constraints provided, i.e., observations that relate one feature to another, is large. A classical approach is to linearize the problem at the current configuration and reducing it to a problem of the form Ax = b.

Typically, a LiDAR SLAM system consists of front-end odometry and back-end optimization modules. Loop closure detection and pose graph optimization are the key factors determining the performance of the …
WebApr 8, 2024 · False-positive loop closure constraints or false-positive landmark observations correspond to additional, erroneous constraint edges in the graph representation of the SLAM problem. Thus the topology of the graph becomes incorrect with respect to the ground truth representation.

In the front-end the SLAM estimates the pose with Ransac as an initial guess for the ICP. With the pose estimation i transform the pointcloud to a pointcloud-scene which represents my map. To smooth the map im trying to implement a graph optimizing …
WebJun 29, 2015 · For these reasons, robust graph optimization or inference for graph-based SLAM has very recently become a strong research focus (Latif et al., 2012a,b; Olson and Agarwal, 2012, 2013; Pfingsthorn and Birk, 2013; Sunderhauf and Protzel, 2012a,b). While a detailed discussion is given in Section 2, these methods fall into roughly two categories.
