CameraIntrinsics

public class CameraIntrinsics

Provides information about the physical characteristics of the device camera, for the camera image (CPU) or texture (GPU). The CameraIntrinsics is a long-lived object, and the properties of CameraIntrinsics may be updated every time Session.update() is called.

Protected Constructors

CameraIntrinsics() (FOR TESTING) Constructs a new instance for use as a mock.

Public Methods

float[]	getFocalLength() Returns a float[2] containing the focal length.
void	getFocalLength(float[] focalLength, int offset) Returns the camera's focal point.
void	getImageDimensions(int[] dimensions, int offset) Returns the camera's image dimensions.
int[]	getImageDimensions() Returns a int[2] containing the image dimensions.
float[]	getPrincipalPoint() Returns a float[2] containing the principal point.
void	getPrincipalPoint(float[] principalPoint, int offset) Returns the camera's principal point.

(FOR TESTING) Constructs a new instance for use as a mock. Calling any base method implementation on this instance may return unexpected results, throw an exception, or even crash.

To obtain a CameraIntrinsics normally, use getImageIntrinsics().

Public Methods

public float[] getFocalLength ()

Returns a float[2] containing the focal length. The order of values is {fx, fy}.

public void getFocalLength (float[] focalLength, int offset)

Returns the camera's focal point. The order of values is {fx, fy}.

Parameters

focalLength	storage for at least 2 floats representing the focal length.
offset	the offset in focalLength at which to begin writing the focal length values.

public void getImageDimensions (int[] dimensions, int offset)

Returns the camera's image dimensions. The order of values is {width, height}.

Parameters

dimensions	storage for at least 2 ints representing the image's width and height.
offset	the offset in dimensions at which to begin writing the image dimension's values.

public int[] getImageDimensions ()

Returns a int[2] containing the image dimensions. The order of values is {width, height}.

public float[] getPrincipalPoint ()

Returns a float[2] containing the principal point. The order of values is {cx, cy}.

public void getPrincipalPoint (float[] principalPoint, int offset)

Returns the camera's principal point. The order of values is {cx, cy}.

Parameters

principalPoint	storage for at least 2 floats representing the principal point.
offset	the offset in principalPoint at which to begin writing the principal point's values.
