Changelog

Version 1.3.0​

New Features​

  • Added support for the Light Flicker Detection stream: the tool now recognizes this stream and reports it in the output JSON as Light Flicker Detection Data Class, with a bad check for malformed records
  • Reworked Meta Neural Band health checking to be based on the batch sequence number rather than on timestamp cadence, which is unreliable for the stream's bursty batch timestamps. Under EMG Data Class (emg_imu_batch) this adds:
    • ratio_dropped_batches_over_expected: batches missing from the sequence, over the number expected across the observed span (fail 50% / warn 10%)
    • non_monotonic_sequence: batches whose sequence number goes backwards
    • zero_channel_count and mismatched_channel_count: batches whose EMG channel count is absent or inconsistent
    • ratio_dropped_over_expected is now ignored for this stream, superseded by the sequence-based ratio above
  • Added recording-level temperature tracking to camera stats: min_temperature_c and max_temperature_c report the coldest and hottest frame temperature seen across the whole recording, alongside the existing temperature_out_of_range count. Cameras without a temperature probe (for example the eye-tracking cameras) report non-finite values and are skipped

Configuration Updates​

AriaGen2_CI configuration:​

  • Tightened IMU drop and timing thresholds, so CI recordings are held to a stricter standard than the general-purpose configurations

Bug Fixes​

  • The wheel no longer installs a top-level _core_pybinds module. It was built and packaged unintentionally, and because projectaria-tools installs a module of the same name, whichever package was installed second silently overwrote the other's copy — leaving import projectaria_tools failing with an ImportError when this package won. The two packages can now be installed in either order

Version 1.2.1​

New Features​

  • Added support for the Proximity Sensor stream: the tool now recognizes this stream and reports it in the output JSON
  • Added duration-aware threshold overrides for numeric checks: thresholds can now declare relaxed values that apply only to short recordings, via a new duration_overrides field (see Configurations and Threshold Checks)
  • Added new camera timing check ratio_large_deviation_over_total: the percentage of frames whose timing deviates from the expected period by more than a configurable amount

Configuration Updates​

AriaGen2_Default configuration:​

  • Added Proximity Sensor Data Class checks (only applied to recordings whose firmware emits this stream)
  • Relaxed GPS start_offset_from_file_us warn threshold from 3,000,000µs to 6,000,000µs
  • Added a duration override for GPS ratio_dropped_over_expected: recordings ≤ 60s use fail 10% / warn 5% (default remains fail 2% / warn 1%)
  • Disabled GPS percentage_inaccurate_samples and percentage_invalid_raw_measurement_samples (set ignore: true) to reduce false warnings on valid-but-inaccurate GNSS fixes

AriaGen2_Location configuration:​

  • Camera timing: removed largest_deviation_from_period_us fail threshold (kept warn_threshold at 250µs)
  • Camera timing: added ratio_large_deviation_over_total fail threshold at 0.1%, using a 500µs deviation threshold

Bug Fixes​

  • Fixed camera large-deviation frame counting so it now matches the periodic stream's behavior
  • Lowered the log level of the calib_json_tag_correct check from error to warning when an unexpected exception occurs (the check result is still reported in the final summary)

Version 1.2.0​

New Features​

  • Added thresholds_version field to output JSON for better version tracking of check configurations

Configuration Updates​

AriaGen2_Handtracking configuration:​

  • Updated thresholds version from v1.0 to v2.0
  • Changed base configuration from AriaGen2_Location to AriaGen2_Default
  • Added slam_imu_streams_present file-level check
  • Added dedicated thresholds for Camera Data (SLAM), IMU Data (SLAM), and RGB Camera Class
  • Relaxed IMU drop ratio fail threshold from 0.2% to 1%
  • Added ignore rules for non-essential streams (Eye Camera, Magnetometer, Audio, Barometer, Wifi, Bluetooth, PPG, Battery, ALS, Pose, Gaze, GPS, Temperature, Time Domain Mapping)

Version 1.1.0​

Configuration Updates​

AriaGen2_Default configuration:​

  • Updated BLE RSSI valid range from < 0.0 to [-127.0, 20.0] or == +127.0
  • Changed GPS drop ratio warn threshold from 5% to 2%
  • Increased longest repeating gyro fail threshold from 10 to 15
  • Relaxed VIO drop ratio fail threshold from 2% to 5%, added warn threshold at 2%
  • Relaxed hand tracking drop ratio fail threshold from 2% to 5%, added warn threshold at 2%

AriaGen1_* configuration:​

  • Updated Aria Gen1 SLAM camera exposure valid range from [0.10ms, 48ms] to [0.019ms, 14ms]

New Features​

  • Added streams_match_profile check to verify expected stream counts match recording profile (Aria Gen2 only)

Version 1.0.0​

  • Initial release
