Submodules

stytra.hardware.video.cameras.abstract_class module

stytra.hardware.video.cameras.avt module

class stytra.hardware.video.cameras.avt.AvtCamera(downsampling=None, **kwargs)[source]

Bases: stytra.hardware.video.cameras.interface.Camera

Class for controlling an AVT camera.

Uses the Vimba interface pymba (module documentation here).

open_camera()[source]

Parameters:
  • param –
  • val –
read()[source]
release()[source]

stytra.hardware.video.cameras.mikrotron module

class stytra.hardware.video.cameras.mikrotron.MikrotronCLCamera(*args, camera_id='img0', **kwargs)[source]

Bases: stytra.hardware.video.cameras.interface.Camera

open_camera()[source]

Initialise the camera.

set(param, val)[source]

Set exposure time or the framerate to the camera.

Parameters:
  • param (str) – parameter key (‘exposure’, ‘framerate’));
  • val – value to be set (exposure time in ms, or framerate in Hz);
read()[source]

Grab frame from the camera and returns it as an NxM numpy array.

Returns:the grabbed frame, or None if an error occurred.
Return type:np.array
release()[source]

Close the camera.

stytra.hardware.video.cameras.opencv module

class stytra.hardware.video.cameras.opencv.OpenCVCamera(cam_idx=0, **kwargs)[source]

Bases: stytra.hardware.video.cameras.interface.Camera

Class for simple control of a camera such as a webcam using opencv. Tested only on a simple USB Logitech 720p webcam. Exposure and framerate seem to work. Different cameras might have different problems because of the camera-agnostic opencv control modules. Moreover, it might not work on a macOS because of system-specific problems in the multiprocessing Queues().
