Name
change_radial_distortion_pointsT_change_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointschange_radial_distortion_points — Change the radial distortion of pixel coordinates.
Signature
def change_radial_distortion_points(row: Sequence[float], col: Sequence[float], cam_param_in: Sequence[Union[int, float, str]], cam_param_out: Sequence[Union[int, float, str]]) -> Tuple[Sequence[float], Sequence[float]]
Description
change_radial_distortion_pointschange_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointsChangeRadialDistortionPointschange_radial_distortion_points changes the radial
distortion of input image coordinates (RowRowRowRowrowrow, ColColColColcolcol)
in accordance to the internal camera parameters CamParamInCamParamInCamParamInCamParamIncamParamIncam_param_in
and CamParamOutCamParamOutCamParamOutCamParamOutcamParamOutcam_param_out. Each input pixel (RowRowRowRowrowrow,
ColColColColcolcol) is transformed into the image plane using
CamParamInCamParamInCamParamInCamParamIncamParamIncam_param_in and projected into another image using
CamParamOutCamParamOutCamParamOutCamParamOutcamParamOutcam_param_out.
Please note that change_radial_distortion_pointschange_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointsChangeRadialDistortionPointschange_radial_distortion_points does not
work for line scan cameras with perspective lenses.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
