Function Documentation

toQuaternion() [1/5]

tf2::Quaternion tf2::impl::toQuaternion ( const tf2::Quaternion & q )

inline

Function needed for the generalization of toQuaternion

Parameters

q	a tf2::Quaternion

Returns

a copy of the same quaternion

toQuaternion() [2/5]

tf2::Quaternion tf2::impl::toQuaternion ( const geometry_msgs::msg::Quaternion & q )

inline

Function needed for the generalization of toQuaternion

Parameters

q	a geometry_msgs::msg::Quaternion

Returns

a copy of the same quaternion as a tf2::Quaternion

toQuaternion() [3/5]

tf2::Quaternion tf2::impl::toQuaternion ( const geometry_msgs::msg::QuaternionStamped & q )

inline

Function needed for the generalization of toQuaternion

Parameters

q	a geometry_msgs::msg::QuaternionStamped

Returns

a copy of the same quaternion as a tf2::Quaternion

toQuaternion() [4/5]

template<typename T>

tf2::Quaternion tf2::impl::toQuaternion

(

const tf2::Stamped< T > &

t

)

Function needed for the generalization of toQuaternion

Parameters

t	some tf2::Stamped object

Returns

a copy of the same quaternion as a tf2::Quaternion

toQuaternion() [5/5]

template<typename T>

tf2::Quaternion tf2::impl::toQuaternion

(

const T &

t

)

Generic version of toQuaternion. It tries to convert the argument to a geometry_msgs::msg::Quaternion

Parameters

t	some object

Returns

a copy of the same quaternion as a tf2::Quaternion

getEulerYPR()

void tf2::impl::getEulerYPR ( const tf2::Quaternion & q, double & yaw, double & pitch, double & roll )

inline

The code below is blantantly copied from urdfdom_headers only the normalization has been added. It computes the Euler roll, pitch yaw from a tf2::Quaternion It is equivalent to tf2::Matrix3x3(q).getEulerYPR(yaw, pitch, roll);

Parameters

q	a tf2::Quaternion
yaw	the computed yaw
pitch	the computed pitch
roll	the computed roll

getYaw()

double tf2::impl::getYaw ( const tf2::Quaternion & q )

inline

The code below is a simplified version of getEulerRPY that only returns the yaw. It is mostly useful in navigation where only yaw matters

Parameters

q	a tf2::Quaternion

Returns

the computed yaw
