slam 要在linux下运行 运行结果很好 不过需要打内存来实现-slam to run under linux running good results but it needs to fight memory to achieve

实时定位与建图（SLAM），用激光传感器采集周围环境信息，建立环境地图，并计算当前机器人的位姿。- Simultaneous Localization and Mapping (SLAM), with a laser sensor to collect information on the surrounding environment, the establishment of an environment map, and calculate the current position a

在进行室内点云匹配的时候，可以进行激光SLAM算法的点云场景。(The point cloud scene of the laser SLAM algorithm can be carried out when indoor point cloud matching is performed.)

cartographer ros程序：SLAM(实时同步定位与地图算法）,在ROS 系统下使用可完成2D 和室内地图构建(Real time synchronous location and mapping system (SLAM), providing ROS system support for 2D and indoor map building.)
