Description

change_radial_distortion_pointschange_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointsChangeRadialDistortionPoints changes the radial distortion of input image coordinates (RowRowRowRowrow, ColColColColcol) in accordance to the internal camera parameters CamParamInCamParamInCamParamInCamParamIncamParamIn and CamParamOutCamParamOutCamParamOutCamParamOutcamParamOut. Each input pixel (RowRowRowRowrow, ColColColColcol) is transformed into the image plane using CamParamInCamParamInCamParamInCamParamIncamParamIn and projected into another image using CamParamOutCamParamOutCamParamOutCamParamOutcamParamOut.

Please note that change_radial_distortion_pointschange_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointsChangeRadialDistortionPoints does not work for line scan cameras.
