Data Loading

Using the MILUV devkit, retrieving sensor data by timestamp from experiment default_3_random_0 can be implemented as:

from miluv.data import DataLoader
import numpy as np

mv = DataLoader(
    "default_3_random_0",
    cir=False,
    barometer=False,
    height=False,
)

timestamps = np.arange(0, 10, 1)  # Time in sec

data_at_timestamps = mv.data_from_timestamps(timestamps)

This example can be made elaborate by selecting specific robots and sensors to fetch from at the given timestamps.

from miluv.data import DataLoader
import numpy as np

mv = DataLoader(
    "default_3_random_0",
    cir=False,
    barometer=False,
    height=False,
)

timestamps = np.arange(0, 10, 1)  # Time in sec

robots = ["ifo001", "ifo002"]  # We are leaving out ifo003
sensors = ["imu_px4", "imu_cam"]  # Fetching just the imu data

data_at_timestamps = mv.data_from_timestamps(
    timestamps,
    robots,
    sensors,
)
