CameraFeed

继承： RefCounted < Object

A camera feed gives you access to a single physical camera attached to your device.

描述

A camera feed gives you access to a single physical camera attached to your device. When enabled, Godot will start capturing frames from the camera which can then be used. See also CameraServer.

Note: Many cameras will return YCbCr images which are split into two textures and need to be combined in a shader. Godot does this automatically for you if you set the environment to show the camera image in the background.

信号

format_changed ( )

Emitted when the format has changed.

frame_changed ( )

Emitted when a new frame is available.

枚举

enum FeedDataType:

FeedDataType FEED_NOIMAGE = 0

No image set for the feed.

FeedDataType FEED_RGB = 1

Feed supplies RGB images.

FeedDataType FEED_YCBCR = 2

Feed supplies YCbCr images that need to be converted to RGB.

FeedDataType FEED_YCBCR_SEP = 3

Feed supplies separate Y and CbCr images that need to be combined and converted to RGB.

FeedDataType FEED_EXTERNAL = 4

Feed supplies external image.

enum FeedPosition:

FeedPosition FEED_UNSPECIFIED = 0

Unspecified position.

FeedPosition FEED_FRONT = 1

Camera is mounted at the front of the device.

FeedPosition FEED_BACK = 2

Camera is mounted at the back of the device.

属性说明

bool feed_is_active = false

• void set_active ( value: bool )
• bool is_active ( )

If true, the feed is active.

Transform2D feed_transform = Transform2D(1, 0, 0, -1, 0, 1)

• void set_transform ( value: Transform2D )
• Transform2D get_transform ( )

The transform applied to the camera's image.

Array formats = []

• Array get_formats ( )

Formats supported by the feed. Each entry is a Dictionary describing format parameters.

方法说明

FeedDataType get_datatype ( ) const¹

Returns feed image data type.

int get_id ( ) const¹

Returns the unique ID for this feed.

String get_name ( ) const¹

Returns the camera's name.

FeedPosition get_position ( ) const¹

Returns the position of camera on the device.

int get_texture_tex_id ( feed_image_type: FeedImage )

Returns the texture backend ID (usable by some external libraries that need a handle to a texture to write data).

void set_external ( width: int, height: int )

Sets the feed as external feed provided by another library.

bool set_format ( index: int, parameters: Dictionary )

Sets the feed format parameters for the given index in the formats array. Returns true on success. By default YUYV encoded stream is transformed to FEED_RGB. YUYV encoded stream output format can be changed with parameters.output value:

separate will result in FEED_YCBCR_SEP

grayscale will result in desaturated FEED_RGB

copy will result in FEED_YCBCR

void set_name ( name: String )

Sets the camera's name.

void set_position ( position: FeedPosition )

Sets the position of this camera.

void set_rgb_image ( rgb_image: Image )

Sets RGB image for this feed.

void set_ycbcr_image ( ycbcr_image: Image )

Sets YCbCr image for this feed.
