ScaFoCamera

Inherits from: Camera A software-based camera implementation. This class implements all required abstract methods from the Camera base class. Suitable for development, validation, and scenarios where physical hardware is not available. Attributes: resolution (tuple[int, int]): Image resolution (width, height) _frame_count (int): Counter for tracking number of frames captured

​
Inherited methods

  • From Camera: getData, getCameraIntrinsics, setCameraIntrinsics, getCameraSettings, setCameraSettings

​
init

ScaFoCamera.__init__(resolution: tuple[int, int] = (640, 480), fps: int = 30, camera_model: CameraModel = CameraModel.PINHOLE)
Initialize the ScaFoCamera.
​
Arguments
​
resolution (tuple[int, int])
tuple[int, int]
Image resolution (width, height). Defaults to (640, 480).
​
fps (int)
int
Frames per second (informational only). Defaults to 30.
​
camera_model (CameraModel)
CameraModel
Camera projection model. Defaults to PINHOLE.

​
getImage

ScaFoCamera.getImage(image_type: str = 'rgb', camera_name: str = 'left') -> Optional[Image]
Return an image from the camera.
​
Arguments
​
image_type (str)
str
Type of image to return. Options: ‘rgb’, ‘depth’, ‘left’, ‘right’. Defaults to ‘rgb’.
​
camera_name (str)
str
Camera name for stereo cameras. Options: ‘left’, ‘right’. Defaults to ‘left’.
