## Functions

| Name | Type | Summary |
| --- | --- | --- |
| getFocalLength | FloatArray | Returns the camera's focal length in pixels.The focal length is conventionally represented in pixels. For a detailed explanation, pleasesee[Disecting the Camera Matrix, Part 3: The Intrinsic Matrix](https://ksimek.github.io/2013/08/13/intrinsic).Pixels-to-meters conversion can use `SENSOR_INFO_PHYSICAL_SIZE` and`SENSOR_INFO_PIXEL_ARRAY_SIZE` in the Android Characteristics API. |
| getImageDimensions | IntArray | Returns a `int[2]` containing the image dimensions. The order of values is {width,height}. |
| getPrincipalPoint | FloatArray | Returns a `float[2]` containing the principal point. The order of values is {cx, cy}. |
| toFloatArray | Array<FloatArray> | Returns a `float[3][3]` representing the camera's intrinsic matrix. |
