Hi. I am working on a application where I use Vuforia in Unity for use AR detection in indoor localization. My application works, but I want to modify Unity camera intrinsics parameters with that's one which I obtain after calibration in GML. Can you help me?

Unity camera calibration with specified intrinsics parameteres

Hi,

Unfortunately this cannot be achieved via Unity directly.

If you want to modify the intrinsic parameters, you could feed the camera frames through your own driver.

There are 2 things that need to be done.

1. Taking the frames and sending them to your driver, article on how-to: https://library.vuforia.com/articles/Solution/Working-with-the-Camera

2. Creating the driver itself: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/external-camera.html ( please note that we also have a demo project for android on how to create the driver etc.)

Could you please let me know why do you want to change them? Do you encounter issues on specific devices?

Thank you.
