示例1:
void dart::NoCameraMovementPrior::computeContribution(Eigen::SparseMatrix<float> & JTJ,
Eigen::VectorXf & JTe,
const int * modelOffsets,
const int priorParamOffset,
const std::vector<MirroredModel *> & models,
const std::vector<Pose> & poses,
const OptimizationOptions & opts)
{
// get offsets for selected model in the full parameter space
const Pose & srcPose = poses[_srcModelID];
const int srcDims = srcPose.getReducedDimensions();
const int srcOffset = modelOffsets[_srcModelID];
// get step in parameter space at current optimization state
Eigen::VectorXf paramUpdate = JTJ.block(srcOffset,srcOffset,srcDims,srcDims).triangularView<Eigen::Upper>().solve(JTe.segment(srcOffset,srcDims));
// set camera to model transformation (first 6 parameters) to zero
paramUpdate.head<6>() = Eigen::VectorXf::Zero(6);
// compute jacobian and error to achieve no movement of camera frame
JTe.segment(srcOffset,srcDims) = JTJ.block(srcOffset,srcOffset,srcDims,srcDims) * paramUpdate;
}示例2:
Eigen::SparseMatrix<double> Condi2Joint(Eigen::SparseMatrix<double> Condi, Eigen::SparseVector<double> Pa)

Eigen::SparseMatrix<double> Joint;

Eigen::SparseVector<double> tmp_vec = Condi.block(0, cols, Condi.rows(), 1)*Pa.coeff(cols);

Eigen::SparseMatrix<double> P_norm;
P_norm.resize(P.rows(), P.cols());

//SparseVector<double> A_col_sparse = A_sparse.block(0, i, A_sparse.rows(),1);
