Field Documentation

◆ lower_scale_factor_

double open3d::registration::GlobalOptimizationConvergenceCriteria::lower_scale_factor_

Lower scale factor value.

◆ max_iteration_

int open3d::registration::GlobalOptimizationConvergenceCriteria::max_iteration_

Maximum iteration number for iterative optimization module.

◆ max_iteration_lm_

int open3d::registration::GlobalOptimizationConvergenceCriteria::max_iteration_lm_

Maximum iteration number for Levenberg Marquardt method.

max_iteration_lm_ is used for additional Levenberg-Marquardt inner loop that automatically changes steepest gradient gain.

◆ min_relative_increment_

double open3d::registration::GlobalOptimizationConvergenceCriteria::min_relative_increment_

Minimum relative increments.

Several convergence criteria to determine stability of iterative optimization.

◆ min_relative_residual_increment_

double open3d::registration::GlobalOptimizationConvergenceCriteria::min_relative_residual_increment_

Minimum relative residual increments.

◆ min_residual_

double open3d::registration::GlobalOptimizationConvergenceCriteria::min_residual_

Minimum residual value.

◆ min_right_term_

double open3d::registration::GlobalOptimizationConvergenceCriteria::min_right_term_

Minimum right term value.

◆ upper_scale_factor_

double open3d::registration::GlobalOptimizationConvergenceCriteria::upper_scale_factor_

Upper scale factor value.

Scaling factors are used for levenberg marquardt algorithm these are scaling factors that increase/decrease lambda used in H_LM = H + lambda * I
