Project()

template<typename T >

static absl::StatusOr<Eigen::Vector3<T> > calico::sensors::AccelerometerVectorNavModel::Project ( const Eigen::VectorX< T > &  intrinsics, const Eigen::Vector3< T > &  p_sensor_world_sensor  )

inlinestatic

Returns measurement \(\mathbf{f}\), a 3-D vector such that

\[ \mathbf{f} = \mathbf{S}\mathbf{A}\mathbf{p}^s_{ws} + \mathbf{b}\\\\ \mathbf{S} = \left[\begin{matrix} s_x & 0 & 0\\ 0 & s_y & 0\\ 0 & 0 & s_z \end{matrix}\right], \mathbf{A} = \left[\begin{matrix} 1 & a_1 & a_2\\ a_3 & 1 & a_4\\ a_5 & a_6 & 1 \end{matrix}\right], \mathbf{b} = \left[\begin{matrix}b_x\\b_y\\b_z\end{matrix}\right] \]

Unproject()

template<typename T >

static absl::StatusOr<Eigen::Vector3<T> > calico::sensors::AccelerometerVectorNavModel::Unproject ( const Eigen::VectorX< T > &  intrinsics, const Eigen::Vector3< T > &  measurement  )

inlinestatic

Inverts the measurement model to obtain specific force as observed by the sensor.

\[ \mathbf{p}^s_{ws} = \left(\mathbf{S}\mathbf{A}\right)^{-1} \left(\mathbf{f} - \mathbf{b}\right)\\\\ \mathbf{S} = \left[\begin{matrix} s_x & 0 & 0\\ 0 & s_y & 0\\ 0 & 0 & s_z \end{matrix}\right], \mathbf{A} = \left[\begin{matrix} 1 & a_1 & a_2\\ a_3 & 1 & a_4\\ a_5 & a_6 & 1 \end{matrix}\right], \mathbf{b} = \left[\begin{matrix}b_x\\b_y\\b_z\end{matrix}\right] \]
