Minus Zero Indian Urban Autonomous Driving Dataset - Multicamera LiDAR
Overview
This dataset provides original multicamera autonomous-driving recordings with LiDAR in MCAP format. It is designed for non-commercial research on camera and LiDAR perception, sensor synchronization, H.265 video pipelines, localization, GNSS/pose integration, and robotics data tooling.
The repository uses gated access for personal, educational, and research use under CC BY-NC 4.0. Commercial use is prohibited.
This focused raw release is part of the four-release Indian Urban Autonomous Driving collection. It is preserved without unnecessary clipping or fixed-rate subsampling so researchers can define their own camera–LiDAR synchronization, quality, and split policies.

Dataset structure
The repository contains original .mcap recordings plus integrity and provenance control artifacts. It does not publish MP4, Parquet media derivatives, extracted frames, point-cloud derivatives, or annotations.

<YYYY-MM-DD>/
<recording>.mcap
Camera access units are stored in autonome.CompressedVideos messages and LiDAR records use autonome.LidarFrame. An H.265 access unit inside MCAP is not an MP4 file. The repository tree, MCAP summaries, embedded protobuf descriptors, and decoded values are authoritative; do not infer topology or timing from filenames alone.
Recording duration
Durations below sum each recording's indexed camera log-time span and preserve source timing. They are not wall-clock intervals between separate recordings.

Getting started
Downloading
python -m pip install -U huggingface_hub
REPO_ID="gagandeepreehal/minuszero-indian-autonomous-driving-multicam-lidar"
hf download "$REPO_ID" --repo-type dataset --include "*.mcap" --local-dir ./multicam-lidar-mcap
Download one recording from Python:
from huggingface_hub import hf_hub_download
mcap_path = hf_hub_download(
repo_id="gagandeepreehal/minuszero-indian-autonomous-driving-multicam-lidar",
filename="data/2025-10-22/2025-10-22_15-24-55.520.mcap",
repo_type="dataset",
)
print(mcap_path)
Inspecting channels and messages
python -m pip install -U mcap mcap-protobuf-support
from mcap.reader import make_reader
from mcap_protobuf.decoder import DecoderFactory
path = "<path/to/recording.mcap>"
with open(path, "rb") as stream:
reader = make_reader(stream, decoder_factories=[DecoderFactory()])
for schema, channel, message, decoded in reader.iter_decoded_messages():
print(schema.name, channel.topic, message.log_time, type(decoded).__name__)
Consumers should validate camera identities, array cardinality, timestamps, coordinate frames, point encoding, calibration, and codec parameter sets before use.
Channels and schema reference
Rows remain separate when the same protobuf name has a structurally different embedded descriptor. Files is unique-file coverage for that exact topic and layout; rows can overlap and must not be summed as a corpus total.

How to read the protobuf tables
The tables below are generated from protobuf descriptors embedded in the MCAP summaries. Descriptor presence does not prove that every message populates a field. Repeated arrays can be empty or differ in length, and producer conventions govern unencoded units, coordinate frames, clock domains, calibration order, matrix layout, enums, and numeric ranges.

MCAP is a robotics log container, so embedded camera video and LiDAR are not natively previewable on the Hub. The configured manifest.jsonl appears in Data Studio as an 8-row technical train split indexing repository paths, hashes, ETags, and sizes only.

Intended uses
Appropriate non-commercial uses include:
- multicamera and LiDAR perception or sensor-fusion research;
- robotics and MCAP reader development;
- H.265 extraction, indexing, synchronization, or remuxing experiments;
- LiDAR parsing, timing, calibration, and point-cloud tooling;
- non-commercial teaching, demonstrations, and personal projects.
The dataset is not validated for production driving systems, operational safety decisions, surveillance, identity recognition, or unsupported benchmark claims.
Limitations and known risks
- The dataset is unannotated and does not provide benchmark ground truth.
- Geographic, environmental, temporal, traffic, route, and hardware coverage may be uneven.
- Frames or LiDAR packets can be missing, delayed, duplicated, corrupted, or irregularly spaced.
- Camera and LiDAR streams can start or stop at different times; synchronize with source timestamps rather than array position or decoded index.
- Calibration and protobuf schema versions can differ between recordings.
- H.265 decoding support varies by platform and software build.
- Channel presence does not guarantee that every field is populated; validate each recording.
- LiDAR point encoding, units, axis ordering, handedness, coordinate frames, clock domains, and transforms are producer-defined unless the embedded descriptor states otherwise. Do not infer a hardware-trigger guarantee. See the sensor and timing conventions.
Privacy and responsible use
Recordings may have been captured in public-road environments and may incidentally contain people, faces, vehicle registration plates, residences, businesses, road signs, or precise GNSS/location traces. Do not assume that the data is anonymized.
Users are responsible for applicable privacy, data-protection, publicity, export-control, and local recording laws. Avoid re-identification, tracking individuals, exposing sensitive locations, or combining this dataset with external data in ways that increase privacy risk.
Do not post identifying evidence in a public discussion. Report sensitive, unlawful, or improperly included material privately through the Minus Zero contact form or by email to team@minuszero.ai, using the subject Dataset privacy or takedown request. Include the repository, recording_id or path when known, and enough information to locate the material. The recording-level removal policy applies across all four releases.
