mmpose.apis.webcam.nodes.BaseVisualizerNode

class mmpose.apis.webcam.nodes.BaseVisualizerNode(name: str, input_buffer: str, output_buffer: Union[str, List[str]], enable_key: Optional[Union[str, int]] = None, enable: bool = True)

Base class for nodes whose function is to create visual effects, like visualizing model predictions, showing graphics or showing text messages.

All subclass should implement the method draw().

参数

• name (str) – The node name (also thread name)

• input_buffer (str) – The name of the input buffer

• output_buffer (str | list) – The name(s) of the output buffer(s).

• enable_key (str|int, optional) – Set a hot-key to toggle enable/disable of the node. If an int value is given, it will be treated as an ascii code of a key. Please note: (1) If enable_key is set, the bypass() method need to be overridden to define the node behavior when disabled; (2) Some hot-keys are reserved for particular use. For example: ‘q’, ‘Q’ and 27 are used for exiting. Default: None

• enable (bool) – Default enable/disable status. Default: True
