void load_from(const mrpt::containers::yaml &cfg)

Loads all parameters from a YAML map node.

Public Members

mrpt::math::TVector3D gyroBias = {.0, .0, .0}

Gyroscope (initial or constant) bias, in the local IMU frame of reference (units: rad/s).

mrpt::math::CMatrixDouble33 gyroCov = mrpt::math::CMatrixDouble33::Identity()

Gyroscope covariance (units of sigma are rad/s/√Hz )

std::optional<mrpt::poses::CPose3D> sensorPose

If provided, defines an IMU placed at a pose different than the vehicle origin of coordinates (Default: IMU used as reference of the vehicle frame, i.e. sensorPose = SE(3) identity I_{4x4}).
