Returns count of all elements.

Returns the index of the cell containing the 'point' which may be outside the map, i.e., negative or too large indices that will return false for Cont

Iterator functions for range-based for loops.

Returns 0 if 'trajectory_id' does not exist.

Returns an iterator to the element at 'id' or the end iterator if it does not exist.

Returns Range object for range-based loops over the nodes of a trajectory.

Returns the value stored at 'index', each dimension of 'index' being between 0 and grid_size() - 1.

Casts a ray from origin towards hit for each hit in range data. If 'options.update_free_space' is 'true', all cells along the ray until 'truncation_di

Appends data to a 'trajectory_id', creating trajectories as needed.

Pose of this submap in the local map frame.

Returns the index of the cell containing the 'point'. Indices are integer vectors identifying cells, for this the coordinates are rounded to the next

Number of RangeData inserted.

Returns true if the ProbabilityGrid contains 'cell_index'.

Support querying by trajectory.

Returns the probability of the cell with 'cell_index'.

Returns the cell size in meters. All cells are square and the resolution is the length of one side.

Returns Range object for range-based loops over the trajectory IDs.

Write a message to the bag. @param topic: name of topic @type topic: str @param msg: message to add to bag, or tuple

Compute all pixels that contain some part of the line segment connecting 'scaled_begin' and 'scaled_end'. 'scaled_begin' and 'scaled_end' are scaled b

Close the bag file. Closing an already closed bag does nothing.

Converts an 'index' with each dimension from 0 to 2^'bits' - 1 to a flat z-major index.

Returns an iterator to the first element in the container belonging to trajectory 'trajectory_id' whose time is not considered to go before 'time', or

Query the current time.

Finishes the update sequence.
