Public Member Functions

void set_rho (double rho)
 
double get_coeff (int i) const
 Get coefficient c[i], 0 <= i < 5.
 
void set_coeff (int i, double q)
 Set coefficient c[i], 0 <= i < 6.
 
vec2_type operator() (const vec2_type &p_dn) const
 Remove distortion. p_dn is a point in diagonally normalized coordinates. We compute in dn-coordinates with dn-coefficients.
 
mat2_type jacobi (const vec2_type &p_dn) const
 Analytic version of the Jacobi-matrix. By definition, we are working in dn-coordinates here, not OpenCV.
 
void derive (double *dg, int n_parameters, const vec2_type &p_dn) const
 Derivative wrt distortion coefficients. dg points to an array with N / 2 Elements Not tested!
 
std::ostream & out (std::ostream &cout) const
 The derived class implements a method for printing values inside 3DE4's matrix tool dialog. This functionality is currently not supported by tde4_ld_plugin.
 
- Public Member Functions inherited from ldpk::generic_distortion_base< VEC2, MAT2, 5 >
int get_num_parameters () const
 Number of parameters, that is N.
 
void setup_map_inverse (int n_max_iter, int n_post_iter, double epsilon)
 Configure iterative procedure for map_inverse(). Call this, if you don't agree with the default values.
 
virtual void done ()
 After changing one or more coefficients of the model, call this (future use). The derived class may prepare some data structure for fast/precise evalutation..
 
int get_n_max_iter () const
 User-defined maximum number of iterations applied in map_inverse in order to fulfill the termination condition.
 
int get_n_post_iter () const
 User-defined number of additional iterations to be applied when the termination condition is fulfilled (which we call post-iterations).
 
vec2_type eval (const vec2_type &p) const
 Same as method instead of operator.
 
virtual vec2_type map_inverse (const vec2_type &q) const
 Inverse mapping by solving the fixed point equation without providing initial values. Virtual, because the derived class might use some smart data structure for calculating an initial value.
 
vec2_type map_inverse (const vec2_type &q, const vec2_type &p_start) const
 For given q, we are looking for p so that f(p) = q. p_start is near to p.

 A derived class may check if the index is valid.
