Dear Deqiang, the member m_CameraIntrinsics basically holds the intrinsic parameters of the ToF camera. The initialization of these parameters is based on one instance of the PMD CamCube cameras and thus not applicable for the SR4000.
What you have to do to generate those is to apply some intrinsic calibration method, e.g. the one implemented in OpenCV (http://opencv.itseez.com/trunk/doc/tutorials/calib3d/camera_calibration/camera_calibration.html) and set the calculated parameters for the filter. Unfortunately these parameters cannot be set directly in the ToFUtil plugin but this issue is already on our ToDo list (http://bugs.mitk.org/show_bug.cgi?id=6888).

Any help is very appreciated!
