如何获得相机的内外参数?

ios app上的ARCore和 Android app 上的ARKit 都可以获得相机内外参矩阵, 如

https://developer.apple.com/documentation/arkit/arcamera/2875730-intrinsics和 https://developers.google.com/ar/reference/java/com/google/ar/core/CameraIntrinsics#getPrincipalPoint-principalPoint-offset

请问微信小程序有类似的功能获得CameraContext的光心, 焦距, 等内外参数吗?
