2d Lidar Slam

Using the mutualpromotion mechanism between pose and map, a crosscorrection LiDAR SLAM method is proposed for constructing a highaccuracy 2D map of problematic scenarios In the proposed method, the initial pose is corrected to promote rough mapping, and then the correction of the rough map can provide feedback for the global pose optimization.
