poulet_py.hardware.camera.basler module#
- class BaslerCamera(max_cameras=2)[source]#
Bases:
objectA class to interact with multiple Basler cameras using pypylon and OpenCV. Each camera will record to its own video file and log timestamps to a CSV.
- __init__(max_cameras=2)[source]#
Initializes the BaslerCamera object by enumerating devices and attaching up to max_cameras.
- Args:
max_cameras (int): The maximum number of cameras to use.
- set_frames_per_second(frames_per_second)[source]#
Sets the frame rate for each camera.
- Args:
frames_per_second (float): Desired frame rate in frames per second.
- set_error_log_path(path, file_name)[source]#
Sets the error log file.
- Args:
path (str): Directory for the error log. file_name (str): Name of the error log file.
- set_output_file(path, extra_name, base_file_name='basler-camera')[source]#
Sets up output video files and timestamp CSV files for all cameras.
- Args:
path (str): Directory to save the output files. extra_name (str): Extra name to add to the file names. base_file_name (str): Base name for the files.
- save_timestamp(camera_index, timestamp)[source]#
Save a timestamp to the CSV file for the specified camera.
- Args:
camera_index (int): Index of the camera. timestamp (float): Timestamp to record.
- capture_frame()[source]#
Captures a single frame from whichever camera has a frame ready. The frame is written to its corresponding video file and timestamp logged.
- stream_video(window_width=None, window_height=None)[source]#
Streams the live video feed from all cameras. Each camera is shown in its own window.
- Args:
window_width (int, optional): Width to resize the window. window_height (int, optional): Height to resize the window.
- save_metadata(base_file_name='basler-camera', extra_name='')[source]#
Saves metadata about the recording for each camera to a JSON file.
- Args:
path (str): Directory to save the metadata files. base_file_name (str, optional): Base name for the metadata files. extra_name (str, optional): Extra name to add to the file names.
