Class slamcore::TrajectorySubsystemInterface

class TrajectorySubsystemInterface : public SubsystemInterface 

Subsystem for accessing trajectories.

A common way of using this subsystem would be as follows:

// Get subsystem from the SLAM system
const auto subsystem = slam->getSubsystem<slamcore::TrajectorySubsystemInterface>();

// Fetch most recent trajectories
subsystem->fetch();

// You can retrieve some data
const auto unoptimisedTrajectory = subsystem->getUnoptimisedTrajectory();
const auto optimisedTrajectory = subsystem->getOptimisedTrajectory();
const auto trackingStatus = subsystem->getTrackingStatus();

// Or you can write the trajectories as csv files to an output directory
subsystem->write("trajectories");

Note

There are some positioning modes where the optimised trajectory is not produced. In these cases, getOptimisedTrajectory will return nullptr.

Note

Not thread safe.
