change_radial_distortion_contours_xldT_change_radial_distortion_contours_xldChangeRadialDistortionContoursXldChangeRadialDistortionContoursXld (Operator)

Name

change_radial_distortion_contours_xldT_change_radial_distortion_contours_xldChangeRadialDistortionContoursXldChangeRadialDistortionContoursXld — Change the radial distortion of contours.

Signature

Description

change_radial_distortion_contours_xldchange_radial_distortion_contours_xldChangeRadialDistortionContoursXldChangeRadialDistortionContoursXldChangeRadialDistortionContoursXld changes the radial distortion of the input contours ContoursContoursContoursContourscontours in accordance to the internal camera parameters CamParamInCamParamInCamParamInCamParamIncamParamIn and CamParamOutCamParamOutCamParamOutCamParamOutcamParamOut. Each subpixel of an input contour is transformed into the image plane using CamParamInCamParamInCamParamInCamParamIncamParamIn and subsequently projected into a subpixel of the corresponding contour in ContoursRectifiedContoursRectifiedContoursRectifiedContoursRectifiedcontoursRectified using CamParamOutCamParamOutCamParamOutCamParamOutcamParamOut.

If CamParamOutCamParamOutCamParamOutCamParamOutcamParamOut was computed via change_radial_distortion_cam_parchange_radial_distortion_cam_parChangeRadialDistortionCamParChangeRadialDistortionCamParChangeRadialDistortionCamPar, the contours ContoursRectifiedContoursRectifiedContoursRectifiedContoursRectifiedcontoursRectified are equivalent to ContoursContoursContoursContourscontours obtained with a lens with a modified radial distortion. If the contours are rectified. A subsequent pose estimation (determination of the external camera parameters) is not affected by this operation.

Please note that change_radial_distortion_contours_xldchange_radial_distortion_contours_xldChangeRadialDistortionContoursXldChangeRadialDistortionContoursXldChangeRadialDistortionContoursXld 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.
