class AFL.automation.instrument.RGBCamera.RGBCamera(overrides=None)

Driver for capturing RGB images and computing average RGB values.

This driver interfaces with a USB camera to capture images and extract the average RGB values along with image metadata.

defaults = {'camera_index': 0, 'hough_radii': 40, 'px_crop': [220, 350], 'py_crop': [120, 250], 'save_path': '/home/afl642/rgb_images/'}

__init__(overrides=None)

Initialize RGBCamera driver.

Parameters:

overrides (dict, optional) – Configuration overrides for PersistentConfig.

capture_rgb(name='', plotting=False, **kwargs)

Capture an image and compute average RGB values.

Parameters:

• name (str, optional) – Name/identifier for the measurement.

• plotting (bool, optional) – If True, save diagnostic plots of the captured image.

• **kwargs (dict) – Additional arguments passed to image collection.

Returns:

Dataset with average RGB values, image, and metadata.

Return type:

xarray.Dataset
