GoogleARCore.Frame.CameraImage

Container for state related to the ARCore camera for the frame.

Summary

Properties
`ImageDisplayUvs`	`static DisplayUvCoords` Gets UVs that map the orientation and aspect ratio of the image returned by Frame.CameraImage.AcquireCameraImageBytes to that of the device's display.
`ImageIntrinsics`	`static CameraIntrinsics` Gets the unrotated and uncropped intrinsics for the image (CPU) stream.
`Texture`	`static Texture` Gets a texture used from the device's rear camera.
`TextureDisplayUvs`	`static DisplayUvCoords` Gets UVs that map the orientation and aspect ratio of Frame.CameraImage.Texture to those of the device's display.
`TextureIntrinsics`	`static CameraIntrinsics` Gets the unrotated and uncropped intrinsics for the texture (GPU) stream.

Public static functions
`AcquireCameraImageBytes()`	`GoogleARCore.CameraImageBytes` Attempts to acquire the camera image for CPU access that corresponds to the current frame.
`GetCameraProjectionMatrix(float nearClipping, float farClipping)`	`Matrix4x4` Gets the projection matrix for the frame.
`TransformCoordinate(Vector2 coordinate, DisplayUvCoordinateType sourceType, DisplayUvCoordinateType targetType)`	`Vector2` Transforms a coordinate between the `source` and `target` display UV coordinate types.
`UpdateDepthTexture(ref Texture2D depthTexture)`	`DepthStatus` Updates the input texture with the latest depth data from ARCore.

static DisplayUvCoords ImageDisplayUvs

Gets UVs that map the orientation and aspect ratio of the image returned by Frame.CameraImage.AcquireCameraImageBytes to that of the device's display.

static CameraIntrinsics ImageIntrinsics

Gets the unrotated and uncropped intrinsics for the image (CPU) stream.

static Texture Texture

Gets a texture used from the device's rear camera.

static DisplayUvCoords TextureDisplayUvs

Gets UVs that map the orientation and aspect ratio of Frame.CameraImage.Texture to those of the device's display.

static CameraIntrinsics TextureIntrinsics

Gets the unrotated and uncropped intrinsics for the texture (GPU) stream.

GoogleARCore.CameraImageBytes AcquireCameraImageBytes()

Attempts to acquire the camera image for CPU access that corresponds to the current frame.

Depending on device performance, this can fail for several frames after session start, and for a few frames at a time while the session is running.

Details
Returns	A `CameraImageBytes` struct with `IsAvailable` property set to `true` if successful and `false` if the image could not be acquired.

Matrix4x4 GetCameraProjectionMatrix(
  float nearClipping,
  float farClipping
)

Gets the projection matrix for the frame.

Details

Parameters

`nearClipping`	The near clipping plane for the projection matrix.
`farClipping`	The far clipping plane for the projection matrix.

Returns

The projection matrix for the frame.

Vector2 TransformCoordinate(
  Vector2 coordinate,
  DisplayUvCoordinateType sourceType,
  DisplayUvCoordinateType targetType
)

Transforms a coordinate between the source and target display UV coordinate types.

This can be used for the conversion of coordinates accessed in the same Unity update.

Details

Parameters

`coordinate`	The coordinate to transform.
`sourceType`	The source type of the desired transformation matrix.
`targetType`	The target type of the desired transformation matrix.

Returns

A corresponding position in the target frame.

DepthStatus UpdateDepthTexture(
  ref Texture2D depthTexture
)

Updates the input texture with the latest depth data from ARCore.

If there is no new data, or an error occurs, the contents of the texture will remain unchanged. See DepthStatus for a complete list of reasons.

Details

Parameters

depthTexture

The texture to hold the depth data.

Returns

DepthStatus.Success if successful.
