Depth map undistort

[RongxuanTan]

I would like to perform depth map evaluation on the ETH3D dataset. To do so, I need to convert the distorted depth map into an undistorted one. I have implemented image distortion removal according to the documentation and achieved good results. However, the generated image does not match the undistorted image provided by the dataset. Can you provide some ideas on how you can transform the distorted image from an undistorted image? thank you.
