# KITTI Odometry sequence -> raw date/drive/frame-range mapping.
#
# Verified verbatim against the official KITTI odometry devkit's
# `devkit/readme.txt` ("Nr. / Sequence name / Start / End" table), fetched
# directly (not recalled from memory) on 2026-07-12 from a devkit mirror
# (github.com/alexkreimer/odometry, devkit/readme.txt), and cross-checked
# against a second independent source. `frame_count = end - start + 1`.
#
# `start`/`end` are 0-based indices into the raw drive's image_02 /
# velodyne_points file sequence (e.g. sequence 08 does NOT start at raw
# frame 0 -- it shares drive 0028 with the tail of what would otherwise be
# an even longer capture). `frame_count` is the number of frames belonging
# to the odometry sequence, which can be smaller than the raw drive's total
# frame count (the raw drive may extend beyond the packaged benchmark
# sub-range).
#
# Sequence 03 (2011_09_26_drive_0067) is EXCLUDED from generation (available:
# false): its raw drive is not hosted on KITTI's official S3 mirror --
# confirmed directly (HTTP 404 on
# https://s3.eu-central-1.amazonaws.com/avg-kitti/raw_data/2011_09_26_drive_0067/2011_09_26_drive_0067_sync.zip
# on 2026-07-12) -- and this is a long-standing, unresolved, community-wide
# gap, not something specific to this project: see
# github.com/alexkreimer/odometry/issues/1 (open since 2018, no working
# alternate source ever posted). We deliberately do not point a published
# benchmark at an unverified third-party copy of this drive. Its mapping row
# is kept below for reference/completeness; `kitti-c2l generate` skips it by
# default (see sequence_mapping.AVAILABLE_SEQUENCES).
#
# split: field is this dataset's own assignment (00-08 train, 09-10 test),
# the field-standard protocol used by RegNet/CalibNet/LCCNet/PseudoCal/
# UniCal/LiREC-Net -- not part of the raw KITTI devkit mapping itself.
