Description:

openpacktoolkit 1.1.0

OpenPack Dataset Toolkit (optk)

"OpenPack Dataset" is a new large-scale multi modal dataset of manual packing process.
OpenPack is an open access logistics-dataset for human activity recognition, which contains human movement and package information from 16 distinct subjects.
This repository provide utilities to explore our exciting dataset.
Dataset Release Note

OpenPack Dataset (v1.0.0)

For preliminary analysis, please start from preprocessed-IMU-with-operation-labels.zip in zenodo.
This preprocessed dataset include IMU data (acc, gyro, quaternion) assosiated with operatopn labels because you don't need to combine data and label.

Work Activity Recognition (PyTorch)
PyTorch code samples for work operation prediction task is available.
See openpack-torch for more dietail.
Timestamp
Each data point is associated with a millisecond-precision unix timestamp.
The following is a snippet that converts a timestamp (an int value) into a datatime.datetime() object with timezone.
import datetime

def timestamp_to_datetime(ts: int) -> datetime.datetime:
"""Convert unix timestamp (milli-second precision) into datatime object. """
timezone_jst = datetime.timezone(datetime.timedelta(hours=9))
dt = datetime.datetime.fromtimestamp(ts / 1000).replace(tzinfo=timezone_jst)
return dt

def datetime_to_timestamp(dt: datetime.datetime) -> int:
"""Convert a datetime object into a milli-second precision timestamp."""
return int(dt.timestamp() * 1000)

ts = 1634885786000

dt_out = timestamp_to_datetime(ts)
ts_out = datetime_to_timestamp(dt_out)
print(f"datetime: {dt_out}") # datetime: 2021-10-22 15:56:26+09:00
print(f"timestamp: {ts_out}") # timestamp: 1634885786000
assert ts_out == ts
