VideoCamera

class VideoCamera(id: int = 0, rgb: bool = True, **kwargs: Any)

Iterate images from a local video camera

Parameters:

• id (int) – Identity of local camera

• kwargs – options applied to image frames, see convert

Connect to a local video camera. For some cameras this will cause the recording light to come on.

The resulting object is an iterator over the frames from the video camera. The iterator returns Image objects.

Example:

>>> from machinevisiontoolbox import VideoCamera
>>> video = VideoCamera(0)
>>> for im in video:
>>>   # process image

alternatively:

>>> img = video.grab()

Note

The value of id is system specific but generally 0 is the first attached video camera.
