It reepresents a scene graph using 3D LiDAR which includes **_Keyframes_** registring the robot poses, **_Walls_** which map wall planes, **_Rooms Layer_** constraining the wall planes using 4 wall-room or 2 wall-room factors, **_Floors_** constraining the rooms within a given floor level. It also supports several graph constraints, such as GPS, IMU acceleration (gravity vector), IMU orientation (magnetic sensor). We have tested this package mostly with Ouster OS-1 and Velodyne (VLP16) sensors in structured indoor environments.
