Pinhole

class sonic.Pinhole

Bases: sonic.DistortionModel

Constructor Summary

Pinhole()

Constructs a Pinhole distortion model, which is simply a “pass-through” distortion model.

Inputs:

None.

Outputs:

• obj (1x1 sonic.Pinhole): Pinhole distortion model object

Method Summary

distort(points)

Takes image plane coordinates and distorts them based on the Pinhole (“passthrough”) model.

Inputs:

• obj (1x1 sonic.Pinhole): Pinhole distortion model object

• points (1x1 sonic.Points2): image plane coordinates of points to distort

Outputs:

• pointsd (1x1 sonic.Points2): image plane coordinates of distorted points

undistort(pointsd)

Takes “distorted” image plane coordinates and undistorts them (notably, no real undistortion occurs since this is a passthrough model).

Inputs:

• obj (1x1 sonic.Pinhole): Pinhole distortion model object

• pointsd (1x1 sonic.Points2): image plane coordinates of

  distorted points

Outputs:

• points (1x1 sonic.Points2): image plane coordinates of undistorted points

• convergeMask (1xn logical): array containing true if the ith point converged, or false if it did not. This is to maintain syntax compatibility with other distortion models, and is always true for this model.
