Description

The Lens node allows the user to simulate the camera image distortion due to the camera lens. A Brown's distortion model with two coefficients both for the radial and tangential distortions is used to simulate image distortion.

Field Summary

  • The center field defines the distortion center. Its value should be between 0 and 1.

  • The radialCoefficients field defines the first and second coefficients of the radial distortion of the Brown's distortion model.

  • The tangentialCoefficients field defines the first and second coefficients of the tangential distortion of the Brown's distortion model. The value of the tangential coefficients are typically smaller than the value of the radial coefficients for standard cameras.
