Vision

This component performs object detection and tracking on input images and outputs a list of detected objects, along with their bounding boxes and confidence scores.

API#

class agents.components.vision.Vision(*, inputs: list[Union[agents.ros.Topic, agents.ros.FixedInput]], outputs: list[agents.ros.Topic], model_client: agents.clients.model_base.ModelClient, config: Optional[agents.config.VisionConfig] = None, trigger: Union[agents.ros.Topic, list[agents.ros.Topic], float] = 1, callback_group=None, component_name: str = 'vision_component', **kwargs)#

Bases: agents.components.model_component.ModelComponent

This component performs object detection and tracking on input images and outputs a list of detected objects, along with their bounding boxes and confidence scores.

Parameters:

  • inputs (list[Union[Topic, FixedInput]]) – The input topics for the object detection. This should be a list of Topic objects or FixedInput objects, limited to Image type.

  • outputs (list[Topic]) – The output topics for the object detection. This should be a list of Topic objects, Detection and Tracking types are handled automatically.

  • model_client (ModelClient) – The model client for the vision component. This should be an instance of ModelClient.

  • config (VisionConfig) – The configuration for the vision component. This should be an instance of VisionConfig. If not provided, defaults to VisionConfig().

  • trigger (Union[Topic, list[Topic], float]) – The trigger value or topic for the vision component. This can be a single Topic object, a list of Topic objects, or a float value for timed components.

  • callback_group (str) – An optional callback group for the vision component. If provided, this should be a string. Otherwise, it defaults to None.

  • component_name (str) – The name of the vision component. This should be a string and defaults to “vision_component”.

Example usage:

image_topic = Topic(name="image", msg_type="Image")
detections_topic = Topic(name="detections", msg_type="Detections")
config = VisionConfig()
model_client = ModelClient(model=DetectionModel(name='yolov5'))
vision_component = Vision(
    inputs=[image_topic],
    outputs=[detections_topic],
    model_client=model_client
    config=config,
)
