Description

change_radial_distortion_pointschange_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointschange_radial_distortion_points changes the radial distortion of input image coordinates (RowRowRowrowrow, ColColColcolcol) in accordance to the internal camera parameters CamParamInCamParamInCamParamIncamParamIncam_param_in and CamParamOutCamParamOutCamParamOutcamParamOutcam_param_out. Each input pixel (RowRowRowrowrow, ColColColcolcol) is transformed into the image plane using CamParamInCamParamInCamParamIncamParamIncam_param_in and projected into another image using CamParamOutCamParamOutCamParamOutcamParamOutcam_param_out.

Please note that change_radial_distortion_pointschange_radial_distortion_pointsChangeRadialDistortionPointsChangeRadialDistortionPointschange_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.
