Functions

void transverseDistortionJacobian(double x, double y, double *jacobian, std::vector<double> const &opticalDistCoeffs)
void computeTransverseDistortion(double ux, double uy, double &dx, double &dy, std::vector<double> const &opticalDistCoeffs)

@description Compute distorted focal plane (dx,dy) coordinate given an undistorted focal plane (ux,uy) coordinate. This uses the third order Taylor approximation to the distortion model.

Parameters:

  • ux – Undistored x

  • uy – Undistored y

  • opticalDistCoeffs – For both X and Y coefficients

Returns:

distortedPoint Newly adjusted focal plane coordinates as an x, y tuple
