Typedefs

typedef std::shared_ptr<EntityBase> EntityOther

Placeholder for generic entity of user-defined types

typedef std::shared_ptr<FactorBase> FactorOther

Placeholder for a generic factor of user-defined types

typedef mrpt::poses::CPose3DInterpolator trajectory_t

We reuse mrpt::poses::CPose3DInterpolator as a time-indexed map of SE(3) poses

typedef std::size_t timestep_t

0-based indices of observations in a dataset

typedef mrpt::containers::yaml Yaml

Convenient typedef to save typing in the MOLA project.

Global Functions

mrpt::math::CMatrixDouble33 incremental_rotation(
    const mrpt::math::TVector3D& w,
    const RotationIntegrationParams& params,
    double dt,
    const mrpt::optional_ref<mrpt::math::CMatrixDouble33>& D_incrR_integratedOmega = std::nullopt
    )

This takes a gyroscope measurement of the angular velocity (ω) and integrates it forward in time for a period dt [s] as:

Rot = Exp((ω-ω_{bias})·dt)

FactorBase& factor_get_base(Factor& f)

Return a reference to the FactorBase associated to the variant f

const FactorBase& factor_get_base(const Factor& f)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
