mphy0026.algorithms.compute_tracked_pointer_posn module

Module to point pointer computations.

mphy0026.algorithms.compute_tracked_pointer_posn.check_tracker_data(tracker_frame, tracker_type, pointer, reference)

Checks what data is valid from tracker.

Parameters:

• tracker_frame – frame of data

• tracker_type – string [vega|aurora|aruco]

• pointer – config information for pointer

• reference – optional config information for reference

Returns:

mphy0026.algorithms.compute_tracked_pointer_posn.compute_tracked_pointer_posn(tracker_frame, tracker_type, pointer, reference, offset, template_mode=False)

Computes the pointer position, or returns None if not enough items tracked.

Parameters:

• tracker_frame – tracker frame

• tracker_type – tracker type must be [vega|aurora|aruco]

• pointer – config information for pointer

• reference – optional config information for reference

• offset – 4x1 tip offset in pointer coordinate system

• template_mode – If True, you can calibrate pointer tip, using ref.

Returns:

1x3 ndarray of pointer tip

mphy0026.algorithms.compute_tracked_pointer_posn.extract_pointer_offset(offset_as_filename)

Given a filename containing a pointer tip offset, returns 4x1 point as ndarray.
