Submodules

senseye_cameras.input.camera_ffmpeg module

class senseye_cameras.input.camera_ffmpeg.CameraFfmpeg(id=0, config=None)

Bases: senseye_cameras.input.input.Input

Opens a camera using ffmpeg.

Args:

id (int/str): id of the ffmpeg camera config (dict): Configuration dictionary. Accepted keywords:

fps (int): framerate of the camera res (tuple): resolution in the format (width, height, channels) block_size (int): how many bytes to read from the camera if the camera outputs a stream of bytes. camera_pixel_format (str): pixel format of the camera (eg: bgr24, uyvy422) format (str): desired output pixel format of the camera (eg: rawvideo, h264)

close()

Properly disposes of the input object.

get_format()

Get os specific format.

open()

Opens the ffmpeg subprocess and logs.

read()

Reads in raw frames.

senseye_cameras.input.camera_pylon module

class senseye_cameras.input.camera_pylon.CameraPylon(id=0, config=None)

Bases: senseye_cameras.input.input.Input

Camera that interfaces with pylon/basler cameras.

Args:

id (int): Id of the pylon camera. config (dict): Configuration dictionary. Accepted keywords:

pfs (str): path to a pfs file. encode_metadata (bool): whether to bake in timestamps/frame number into the frame.

close()

Properly disposes of the input object.

configure()

Pylon camera configuration. Requires the pylon camera to have been opened already. The order of these statements is important. Populates self.config with set values. Logs camera start.

open()

Initializes the input.

read()

senseye_cameras.input.camera_pylon.encode_framenumber(np_image, n)

senseye_cameras.input.camera_pylon.encode_timestamp(np_image, timestamp)

senseye_cameras.input.camera_raw_video module

class senseye_cameras.input.camera_raw_video.CameraRawVideo(id=0, config=None)

Bases: senseye_cameras.input.input.Input

Treats raw video as a camera.

Args:

id (str): path to the raw video file. config (dict): Configuration dictionary. Accepted keywords:

res (tuple): frame size in the format (width, height)

close()

Properly disposes of the input object.

open()

Opens raw video as a bytes file.

read()

Reads in raw video. config[‘res’] dictates how many bytes are read in.

senseye_cameras.input.camera_ueye module

class senseye_cameras.input.camera_ueye.CameraUeye(id=0, config=None)

Bases: senseye_cameras.input.input.Input

Camera that interfaces with ueye cameras.

Args:

id (int): Id of the ueye camera. config (dict): Configuration dictionary. Accepted keywords:

fps (int): desired frames per second exposure (str): desired exposure autofocus (bool): whether to enable autofocus autogain (bool): whether to enable autogain focus_min (int): autofocus lower bound focus_max (int): autofocus upper bound focus for 10 inches is ~780 focus for 20 inches is ~900

close()

Properly disposes of the input object.

initialize_camera_settings()

Sets pixel_clock, fps, exposure, autofocus, autogain based on self.config.

initialize_color_mode()

Initializes color mode. Sets:

self.m_nColorMode self.bits_per_pixel self.bytes_per_pixel

initialize_dimensions()

Gets dimensions of the camera. Sets:

self.width self.height

initialize_memory()

Allocates image memory. Sets:

self.mem_id self.mem_image

initialize_modes()

Enables live video mode. Enables queue mode. Sets:

self.pitch

open()

Opens and initializes ueye camera.

read()

senseye_cameras.input.camera_usb module

class senseye_cameras.input.camera_usb.CameraUsb(id=0, config=None)

Bases: senseye_cameras.input.input.Input

Opens a usb camera or video using OpenCV.

Args:

id (int OR str): id of the camera, or path to a video file. config (dict): Configuration dictionary. Accepted keywords:

res (tuple): frame size codec (str) fps (int)

close()

Properly disposes of the input object.

configure()

Configures the camera using a config. Supported configurations: fps, codec, res

Fills self.config with camera attributes. Logs camera start.

open()

Initializes the input.

read()

Reads in frames. Converts frames from BGR to the more commonly used RGB format.

senseye_cameras.input.input module

class senseye_cameras.input.input.Input(id=0, config=None, defaults=None)

Bases: object

General interface for cameras or other input streams.

close()

Properly disposes of the input object.

open()

Initializes the input.

read()

senseye_cameras.input.input_factory module

senseye_cameras.input.input_factory.create_input(type='usb', *args, **kwargs)

Factory method for creating a video or audio input interface. Supported types: ffmpeg, pylon, raw_video, ueye, usb/video, microphone

senseye_cameras.input.microphone module

class senseye_cameras.input.microphone.Microphone(id=0, config=None)

Bases: senseye_cameras.input.input.Input
