从您给的文本中,我们Neng出用Ceres库进行非线性优化问题的步骤和方法。
创建问题实例
cpp
ceres::Problem problem;

添加本钱函数
用AutoDiffCostFunction或者自定义的CostFunction来定义误差函数,并将其添加到问题中。
cpp
ceres::CostFunction* cost_function = new ceres::AutoDiffCostFunction;
problem.AddResidualBlock;
或者用自定义的误差函数CostFunctor
cpp
ceres::CostFunction* cost_function = new ceres::AutoDiffCostFunction;
problem.AddResidualBlock;
cpp
ceres::Solver::Options options;
options.linear_solver_type = ceres::DENSE_QR;
options.max_num_iterations = 1000;
options.minimizer_progress_to_stdout = true;
cpp
ceres::Solver::Summary summary;
ceres::Solve;
Ceres库也支持数值积分,但具体的实现细节没有在文本中给出。
cpp
ceres::DynamicAutoDiffCostFunction* exponential_cost_function =
new ceres::DynamicAutoDiffCostFunction);
exponential_cost_function->AddParameterBlock;
exponential_cost_function->AddParameterBlock;
exponential_cost_function->AddParameterBlock;
exponential_cost_function->AddParameterBlock;
exponential_cost_function->SetNumResiduals;
设置鲁棒亏本函数
cpp
ceres::LossFunction* loss_function = new ceres::HuberLoss;
创建鲁棒本钱函数并添加到问题中
cpp
ceres::DynamicAutoDiffCostFunction* robust_cost_function =
new ceres::DynamicAutoDiffCostFunction);
robust_cost_function->AddParameterBlock;
robust_cost_function->AddParameterBlock;
robust_cost_function->AddParameterBlock;
robust_cost_function->SetNumResiduals;
problem.AddResidualBlock;
Ceres库是一个功Neng有力巨大的非线性优化工具,Neng用于解决各种非线性Zui细小二乘问题。通过设置合适的优化选项和鲁棒性,Neng得到geng准准的和鲁棒的优化后来啊。
