2005 DARPA Grand Challenge winner Stanley performed SLAM as part of its autonomous driving system. A map generated by a SLAM Robot. Simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.
This is a list of simultaneous localization and mapping (SLAM) methods. The KITTI Vision Benchmark Suite website has a more comprehensive list of Visual SLAM methods.
The problem of simultaneous localization and mapping also fits the framework of invariant extended Kalman filtering after embedding of the state (consisting of attitude matrix , position vector and a sequence of static feature points , …,) into the Lie group + (or + for planar systems) [8] defined by the group operation:
Map learning cannot be separated from the localization process, and a difficulty arises when errors in localization are incorporated into the map. This problem is commonly referred to as Simultaneous localization and mapping (SLAM).
Point set registration is the process of aligning two point sets. Here, the blue fish is being registered to the red fish. In computer vision, pattern recognition, and robotics, point-set registration, also known as point-cloud registration or scan matching, is the process of finding a spatial transformation (e.g., scaling, rotation and translation) that aligns two point clouds.
Given 3D point = (,,) with world coordinates in a reference frame (,,), observed from different views, the inverse depth parametrization of is given by: = (,,,,,) where the first five components encode the camera pose in the first observation of the point, being = (,,) the optical centre, the azimuth, the elevation angle, and = ‖ ‖ the inverse depth of at the first observation.
Originally introduced for 2D point cloud map matching in simultaneous localization and mapping (SLAM) and relative position tracking, [1] the algorithm was extended to 3D point clouds [2] and has wide applications in computer vision and robotics. NDT is very fast and accurate, making it suitable for application to large scale data, but it is ...
slam toolbox [80] provides full 2D SLAM and localization system. gmapping [81] provides a wrapper for OpenSlam's Gmapping algorithm for simultaneous localization and mapping. cartographer [82] provides real time 2D and 3D SLAM algorithms developed at Google. amcl [83] provides an implementation of adaptive Monte-Carlo localization.
