WebOct 23, 2024 · Cartographer has both 2D and 3D SLAM, but this guide will focus only on the 2D SLAM. One of Cartographer’s strength is that its 2D SLAM is aware of the 3D world (it will project a titled LiDAR scan to the horizontal axis). This is in contrast to gmapping which requires the LaserScan to always be perfectly level and horizontal. WebAug 3, 2024 · This prevents angular decompensation in the case you are using rotary LIDAR, and also gives Gmapping algorithm the time to perform scan matching.
