Questions about camera intrinsics

General
1

hello. I am developing a Magic Leap app using Unreal.

The Camera Intrinsic value (3x3 matrix) of the main camera is required. How can I get the value?

I checked the MagicLeapCamera plug-in source, but I couldn't find the Camera Intrinsic value.

Is it possible to get the Camera Intrinsic value using adb?

I'm not sure i understand. Are you referring to the RGB Camera on the front of the Magic Leap 2 device, or the camera in the Unreal Engine scene that renders the content?

If you are referring to the RGB Camera, you cannot access the intrinsic values using ADB. Magic Leap 2 is compatible with the standard Android Camera NDK . If you are creating a a native plugin you can obtain the intrinsic from Android's Capture Complete callback.

Thank you for answer.
The camera is Magic Leap's RGB camera.
You mean to get the value using the Android API, right?
I'll give it a try. thank you
