hdl_graph_slam supports several GPS message types. All the supported types contain (latitude, longitude, and altitude). hdl_graph_slam converts them intothe UTM coordinate, and adds them into the graph as 3D position constraints. If altitude is set to NaN, the GPS data is treated as a 2D...
HDL graph slam有四个主要线程,对于点云的预处理降采样prefiltering线程,floor detection线程(检测一个共有的平面作为地面),odometry线程(在测试中使用的是使用openmp加速的NDT算法),和graph optimization线程(优化包括:相邻帧的约束,回环约束,和每一帧检测到的地面约束)。 HDL – prefiltering the maximum time is :...
