Constant methods for crate::calib3d::LMSolver_Callback

Required Methods§

source

fn as_raw_LMSolver_Callback(&self) -> *const c_void

Provided Methods§

source

fn compute( &self, param: &impl ToInputArray, err: &mut impl ToOutputArray, j: &mut impl ToOutputArray ) -> Result<bool>

computes error and Jacobian for the specified vector of parameters

Parameters
  • param: the current vector of parameters
  • err: output vector of errors: err_i = actual_f_i - ideal_f_i
  • J: output Jacobian: J_ij = d(ideal_f_i)/d(param_j)

when J=noArray(), it means that it does not need to be computed. Dimensionality of error vector and param vector can be different. The callback should explicitly allocate (with “create” method) each output array (unless it’s noArray()).

Object Safety§

This trait is not object safe.
