And of course, the inliers are now filtered to the biggest cluster present in the raw RANSAC inlier set. When the loop is over, you get a clean set of segments holding spatially contiguous point sets that follow planar … SLAM aims to solve self-localization and unknown-environment map build-up problems for mobile robots. With the help of SLAM, mobile robots can know where it is, how the surroundings are, and know how to act autonomously in the next step. The main sensors that SLAM uses are lidar and cameras. how to lose weight now
