virtual bool openFile(const std::string &filename)

Protected Functions

inline bool isInUpdateBBX(const OcTreeT::iterator &it) const: Test if key is within update area of map (2D, ignores height)

rcl_interfaces::msg::SetParametersResult onParameter(const std::vector<rclcpp::Parameter> &parameters)

void publishBinaryOctoMap(const rclcpp::Time &rostime) const

void publishFullOctoMap(const rclcpp::Time &rostime) const

virtual void publishAll(const rclcpp::Time &rostime)

virtual void insertScan(const tf2::Vector3 &sensor_origin, const PCLPointCloud &ground, const PCLPointCloud &nonground)

update occupancy map with a scan labeled as ground and nonground. The scans should be in the global map frame.

Parameters:

sensor_origin – origin of the measurements for raycasting
ground – scan endpoints on the ground plane (only clear space)
nonground – all other endpoints (clear up to occupied endpoint)

void filterGroundPlane(const PCLPointCloud &pc, PCLPointCloud &ground, PCLPointCloud &nonground) const: label the input cloud “pc” into ground and nonground. Should be in the robot’s fixed frame (not world!)

bool isSpeckleNode(const octomap::OcTreeKey &key) const

Find speckle nodes (single occupied voxels with no neighbors). Only works on lowest resolution!

Parameters:: key –
Returns:

virtual void handlePreNodeTraversal(const rclcpp::Time &rostime): hook that is called before traversing all nodes

inline virtual void handleNode([[maybe_unused]] const OcTreeT::iterator &it): hook that is called when traversing all nodes of the updated Octree (does nothing here)

inline virtual void handleNodeInBBX([[maybe_unused]] const OcTreeT::iterator &it): hook that is called when traversing all nodes of the updated Octree in the updated area (does nothing here)

virtual void handleOccupiedNode(const OcTreeT::iterator &it): hook that is called when traversing occupied nodes of the updated Octree

virtual void handleOccupiedNodeInBBX(const OcTreeT::iterator &it): hook that is called when traversing occupied nodes in the updated area (updates 2D map projection here)

virtual void handleFreeNode(const OcTreeT::iterator &it): hook that is called when traversing free nodes of the updated Octree

virtual void handleFreeNodeInBBX(const OcTreeT::iterator &it): hook that is called when traversing free nodes in the updated area (updates 2D map projection here)

virtual void handlePostNodeTraversal(const rclcpp::Time &rostime): hook that is called after traversing all nodes

virtual void update2DMap(const OcTreeT::iterator &it, bool occupied): updates the downprojected 2D map as either occupied or free

inline size_t mapIdx(const int i, const int j) const

inline size_t mapIdx(const octomap::OcTreeKey &key) const

void adjustMapData(OccupancyGrid &map, const MapMetaData &old_map_info) const: Adjust data of map due to a change in its info properties (origin or size, resolution needs to stay fixed). map already contains the new map info, but the data is stored according to old_map_info.

inline bool mapChanged(const MapMetaData &old_map_info, const MapMetaData &new_map_info)
