Read this page as plain text instead: https://www.nianticspatial.com/docs/llms-api-kotlin/com.nianticspatial.nsdk.CameraIntrinsics.txt — same content, easier to parse than this HTML, with each platform's steps kept separate.

Every page in the current release follows the same pattern, so you can build the URL directly instead of fetching an index: a page at /api/kotlin/<page>/ is at /llms-api-kotlin/<page>.txt.

CameraIntrinsics

Camera intrinsics. This is a copy of the ARCore CameraIntrinsics class.

Declaration

open class CameraIntrinsics

Properties

Name	Type	Summary
focalLengthArray	FloatArray	-
imageDimensionsArray	IntArray	-
principalPointArray	FloatArray	-

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, please see Disecting the Camera Matrix, Part 3: The Intrinsic Matrix. 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.
