Similar function in OpenVX to get the undistorted image (cv2.fisheye.initUndistortRectifyMap)

Hi expert,
I am new to openvx and currently trying to figure out the way to convert my fisheye (larger FOV image) to undistorted one. Is there any help I can receive from the experts? Thank you.

With best regards,

Here is a project on GitHub which uses OpenVX to stitch 360 images. The project does fix lens distortion.
