Member Function Documentation

◆ project2() [1/2]

template<class CAMERA>
template<class POINT >
ZVector gtsam::CameraSet< CAMERA >::project2 ( const POINT &  point,
FBlocks *  Fs = nullptr,
Matrix *  E = nullptr 
) const
inlineinherited

Project a point (possibly Unit3 at infinity), with derivatives Note that F is a sparse block-diagonal matrix, so instead of a large dense matrix this function returns the diagonal blocks. throws CheiralityException

◆ project2() [2/2]

template<class CAMERA>
template<class POINT , class... OptArgs>
ZVector gtsam::CameraSet< CAMERA >::project2 ( const POINT &  point,
OptArgs &...  args 
) const
inlineinherited

An overload o the project2 function to accept full matrices and vectors and pass it to the pointer version of the function

◆ reprojectionError()

template<class CAMERA>
template<class POINT , class... OptArgs, typename = std::enable_if_t<sizeof...(OptArgs)!=0>>
Vector gtsam::CameraSet< CAMERA >::reprojectionError ( const POINT &  point,
const ZVector &  measured,
OptArgs &...  args 
) const
inlineinherited

An overload o the reprojectionError function to accept full matrices and vectors and pass it to the pointer version of the function

◆ SchurComplement() [1/3]

template<class CAMERA>
template<int N, int ND>
static SymmetricBlockMatrix gtsam::CameraSet< CAMERA >::SchurComplement ( const std::vector< Eigen::Matrix< double, ZDim, ND >, Eigen::aligned_allocator< Eigen::Matrix< double, ZDim, ND >>> &  Fs,
const Matrix &  E,
const Eigen::Matrix< double, N, N > &  P,
const Vector &  b 
)
inlinestaticinherited

Do Schur complement, given Jacobian as Fs,E,P, return SymmetricBlockMatrix G = F' * F - F' * E * P * E' * F g = F' * (b - E * P * E' * b) Fixed size version

◆ SchurComplement() [2/3]

template<class CAMERA>
template<int N>
static SymmetricBlockMatrix gtsam::CameraSet< CAMERA >::SchurComplement ( const FBlocks &  Fs,
const Matrix &  E,
const Eigen::Matrix< double, N, N > &  P,
const Vector &  b 
)
inlinestaticinherited

Do Schur complement, given Jacobian as Fs,E,P, return SymmetricBlockMatrix G = F' * F - F' * E * P * E' * F g = F' * (b - E * P * E' * b) Fixed size version

◆ SchurComplement() [3/3]

template<class CAMERA>
static SymmetricBlockMatrix gtsam::CameraSet< CAMERA >::SchurComplement ( const FBlocks &  Fblocks,
const Matrix &  E,
const Vector &  b,
const double  lambda = 0.0,
bool  diagonalDamping = false 
)
inlinestaticinherited

Do Schur complement, given Jacobian as Fs,E,P, return SymmetricBlockMatrix Dynamic version

◆ SchurComplementAndRearrangeBlocks()

template<class CAMERA>
template<int N, int ND, int NDD>
static SymmetricBlockMatrix gtsam::CameraSet< CAMERA >::SchurComplementAndRearrangeBlocks ( const std::vector< Eigen::Matrix< double, ZDim, ND >, Eigen::aligned_allocator< Eigen::Matrix< double, ZDim, ND >>> &  Fs,
const Matrix &  E,
const Eigen::Matrix< double, N, N > &  P,
const Vector &  b,
const KeyVector jacobianKeys,
const KeyVector hessianKeys 
)
inlinestaticinherited

Do Schur complement, given Jacobian as Fs,E,P, return SymmetricBlockMatrix G = F' * F - F' * E * P * E' * F g = F' * (b - E * P * E' * b) In this version, we allow for the case where the keys in the Jacobian are organized differently from the keys in the output SymmetricBlockMatrix In particular: each diagonal block of the Jacobian F captures 2 poses (useful for rolling shutter and extrinsic calibration) such that F keeps the block structure that makes the Schur complement trick fast.

N = 2 or 3 (point dimension), ND is the Jacobian block dimension, NDD is the Hessian block dimension

◆ UpdateSchurComplement()

template<class CAMERA>
template<int N>
static void gtsam::CameraSet< CAMERA >::UpdateSchurComplement ( const FBlocks &  Fs,
const Matrix &  E,
const Eigen::Matrix< double, N, N > &  P,
const Vector &  b,
const KeyVector allKeys,
const KeyVector keys,
SymmetricBlockMatrix augmentedHessian 
)
inlinestaticinherited

Applies Schur complement (exploiting block structure) to get a smart factor on cameras, and adds the contribution of the smart factor to a pre-allocated augmented Hessian.
