UltraVR QA-Only Data Schema

UltraVR annotations are stored in JSONL format. Each line is one QA sample.

This trial version is QA-only: the original reasoning_supervision field has been removed from all questions, and no gt_cot, cot, or chain-of-thought field is included.

Required fields

{
  "sample_id": "string, unique UltraVR QA sample id",
  "domain": "RS | CCTV | AD",
  "source_dataset": "DOTA-v1.5 | PANDA | MVTec LOCO AD",
  "image_path": "string",
  "image_width": "integer or null",
  "image_height": "integer or null",
  "question_id": "string or null",
  "question": "string",
  "question_type": "string or null",
  "options": "object, usually A/B/C/D for multiple choice; may be empty for open-answer AD questions",
  "answer": "string",
  "license_note": "string or null"
}

Field notes

• sample_id is unique across the release and follows ultravr_<domain>_<six_digit_id>.
• image_path is the only image locator in each JSONL record. For AD it points to a local repository file under data/images/ad/. For RS and CCTV it points to the corresponding source-dataset image path.
• question_id preserves the original question identifier from the constructed QA files.
• question_type preserves the original category, such as comparison, logical_verification, or relational_inference.
• options keeps the original answer options. Some AD anomaly-localization questions are open-answer and therefore have {}.
• answer keeps the original answer string. For multiple-choice questions it is usually A, B, C, or D; for open-answer AD questions it can be a coordinate such as (5, 10).
• reasoning_supervision is intentionally omitted.

Domain image policy

Domain	image_path meaning
RS	Source DOTA path, e.g. DOTA-v1.5_val/P0019.png.
CCTV	Source PANDA path, e.g. PANDA/image_train/01_University_Canteen/IMG_01_01.jpg.
AD	Local repository path, e.g. data/images/ad/ad_0001.jpg.

Mapping files

RS and CCTV images are not redistributed. Use these files to map QA samples to source images:

• data/images/rs/mapping.csv
• data/images/cctv/mapping.csv

All paths use POSIX-style / separators and are relative unless they are official source URLs.
