Cropping surface areas from an external image

This tool allows you to automatically crop and align Pupil-Capture-defined surface areas from an external image of the actual surface.

Caveats:

The script will assume that the provided image is not distorted.

Installation

PI Export Utility

This Python script extracts gaze, IMU, and template data from raw Invisible recordings. Gaze and IMU data are exported as CSV files. Template data as json.

Usage: pi-export.py [OPTIONS] [RECORDINGS]...

Options:
 -e, --export-folder TEXT Relative export path [default: `/export`]

Stand-alone Post-hoc Blink Detection

This script reads raw Pupil Capture recordings and applies Pupil Player's Post-hoc Blink Detection algorithm.

Pupil confidence extraction code is based on this example. Blink detection algorithm adapted from Pupil Player source code.

Caveats:

Only supports 2d pupil confidence, does not fall back to 3d pupil confidence if the former is unavailable

Dual-Display HMD Calibration Choreography

The components below allow Pupil Core to calibrate gaze for separate head-mounted displays. As a result, Pupil Core can estimate gaze within custom target coordinate systems for each eye. This is different from the dual-monocular calibrations which calibrate each eye separately but assume the target coordinate system to be the same for both eyes.

There are three major components:

	import pandas as pd

	recording_hdf5 = pd.HDFStore(path_to_hdf5_file, "r")
	binocular_data = recording_hdf5[
	"/data_collection/events/eyetracker/BinocularEyeSampleEvent"
	]
	monocular_data = recording_hdf5[
	"/data_collection/events/eyetracker/MonocularEyeSampleEvent"
	]
