Scripts

`scripts/merge_behavior_telemetry.py`

Merges SRT metadata, detection tracks, and behavior annotations into occurrence files.

Usage:

python scripts/merge_behavior_telemetry.py \
  --data_path /path/to/video/directories \
  --outpath /path/to/output/ \
  [--skip-airdata]

Arguments:

--data_path: Directory containing video folders (format: DATE-VIDEO_ID)
--session_data_path: Path to SRT files (default: preset path)
--flight_logs_path: Path to decrypted flight logs (default: preset path)
--skip-airdata: Skip merging with flight log data
--write: Whether to write output (default: True)
--outpath: Output directory for CSV files

Input Requirements:

Video directories with structure:
- metadata/{video_id}_tracks.xml: Detection bounding boxes
- actions/*.xml: Behavior annotation files
SRT files with GPS and camera metadata
(Optional) Flight log CSV files with telemetry

Output:

One CSV per video in occurrence format

`scripts/update_video_events.py`

Updates video_events.csv with associatedMedia paths to detection and behavior files.

Usage:

python scripts/update_video_events.py \
  --video_events data/video_events.csv \
  --data_path /path/to/video/directories \
  [--output output_path.csv]

Scans video directories for detection and behavior annotation files
Creates relative paths from kabr-behavior-telemetry/data to annotation files
Updates associatedMedia field with JSON structure

`scripts/add_event_times.py`

Extracts start and end times from occurrence files and adds to video_events.csv.

Usage:

python scripts/add_event_times.py \
  --video_events data/video_events.csv \
  --occurrences data/occurrences/ \
  [--output output_path.csv]

  --occurrences data/occurrences/ \
  [--output_video output_video.csv] \
  [--output_session output_session.csv]

What it does:

For video_events.csv:

Extracts launch point (first GPS coordinate)
Calculates min/max lat/lon bounds
Determines altitude range
Creates WKT footprint

For session_events.csv:

Uses first video's launch point as session launch
Aggregates bounds across all videos in session
Formats lat/lon as "[min, max]" ranges
Creates session-level WKT footprint

Quality Assurance

Known Limitations

Missing Occurrence Data: 21 videos lack occurrence files due to:
- Missing SRT files
- Corrupted source data
- Processing errors
- Empty annotations
GPS Accuracy: ±5-10 meters typical
Timestamp Precision: Millisecond resolution but may have ±1 second drift

Data Quality Flags

_needs_verification: Manual review recommended
