No one will be able to help you without more details. Many have successfully used Aximmetry with Antilatency before, so you just need to figure out what step you’ve missed. Have you read the documentation carefully? 

Yes, I read the documentation. Camera calibration is the actual problem. I can't get good results after sets of Origin, Forward Point, and Right Point. 

Hi Kumar,

Origin, Forward Point, and Right Point are used to set the floor's position. It is not a camera calibration.
To do a full camera calibration we suggest using the Camera Calibrator.

You can learn how to use Origin, Forward Point, and Right Point in Richard Frantzén's video.
Starting from Aximmetry version 2023.3.0 you will also be able to set the floor's position using an ArUco marker, this is a much faster method than using the Origin, Forward Point, and Right Point. You can read more about it here.
Note, that Antilatency might give different camera heights after each restart of your Antilatency tracking system, so you might need to do the floor position calculation frequently in your studio.

We have a documentation page for Antilatency here.

Warmest regards,
