[feat] evaluate multisensor odometry in CI - #166
Merged
Merged
Conversation
Add MSF evaluation records for KITTI, TUM and ICL-NUIM, full suite only and informational while the mode is experimental. Each replays the reporter config its existing record already uses, so the MSF rows compare the cuNLS solver against the default one on identical frames and ground truth. EuRoC and M3ED-SPOT get none: the solver projects through a pinhole camera and only warns on the fisheye and polynomial models those two use. Supporting changes: - Reporter output goes to <config stem>-<odometry mode>/<timestamp>/. The KPI collector reads only the newest run under each directory, so two records sharing one config previously overwrote each other. The KPI prefix is the first hyphen-delimited token, so it is unaffected. - The tracker CLI accepts multisensor, and EdexReader builds MultisensorSettings from the EDEX. Its depth parser stopped at the first camera declaring a depth_id; both settings objects now share a parser that reports every depth camera and rejects cameras disagreeing on depth_scale_factor. - KPI types come from one map per odometry mode: multisensor is MSF and the misnamed STEREO becomes MCAM. An unknown mode is rejected rather than filed under another mode's keys. Baseline keys renamed to match. - IMU measurements and gravity now reach multisensor, not just inertial.

In `@scripts/cuvslam_kpi_report.py`:
- Line 111: Update the odometry mode handling around the normalized lookup to
first normalize enum-qualified mode names, then use an exact mapping lookup
rather than substring containment. Unsupported values such as “notmultisensor”
must remain unmapped so the collector warns and skips the run instead of
recording it under a valid KPI type.
In `@tools/python_tools/cuvslam_tools/reporter/cli.py`:
- Line 65: Update run_report’s handling of a non-empty args.output_dir so it
appends the computed run_name before saving stats, isolating each odometry mode
in its own subdirectory. Preserve the existing run_name behavior for empty
output directories and ensure reports no longer overwrite shared
stats/all_stats.json.
In `@tools/python_tools/cuvslam_tools/tracker/edex_reader.py`:
- Around line 559-565: Update the depth_sequence scale handling around
depth_scale_factor so scaling is determined per stream after format conversion
rather than applying 1000.0 globally when any stream uses NPY. Reject
configurations whose effective stream scales differ, or normalize all streams to
a single raw unit, while preserving correct declared scaling for PNG streams.
- Around line 536-547: Update the depth-camera parsing logic to raise ValueError
instead of skipping invalid depth_id values or defaulting invalid
depth_scale_factor values; include the camera index and rejected value in each
error. Preserve normal integer and float conversion for valid configurations,
using the surrounding camera iteration context.
In `@tools/python_tools/cuvslam_tools/tracker/runner.py`:
- Around line 350-351: Update the IMU registration and backward shuttle handling
around process_imu and merge_and_sort_frames_and_imu so multisensor rigs with
IMUs cannot submit decreasing timestamps to Tracker::RegisterImuMeasurement. Add
a rig-aware guard for unsupported reverse IMU replay, or ensure
reverse-direction processing preserves non-decreasing timestamp order while
retaining forward replay behavior.

Test Results
cuVSLAM Evaluation KPIs
Artifacts |
The Run Python tools tests step installs cuvslam_tools without the cuVSLAM binding, so every test module has to import without it. test_edex_reader imported EdexReader, which imports cuvslam at module scope, and a tracker CLI test imported the binding directly, failing the step on both counts. Move the EDEX depth rules into cuvslam_tools.tracker.depth_config, which has no binding dependency, and leave edex_reader holding only the wrappers that turn a DepthDescription into RGBDSettings or MultisensorSettings. That keeps the rules this branch changed under test: every depth camera is reported rather than the first, and cameras disagreeing on depth_scale_factor are rejected. The CLI test now asserts that the parser's accepted odometry modes match the registry's, which needs no binding either.

replay() still gated depth allocation and loading on rgbd_mode, so a multisensor run received depths=None and never loaded a depth image. The TUM and ICL-NUIM MSF records would have tracked RGB-only against a rig declaring depth cameras. Gate on depth_mode and store each stream at the camera index the active mode declared, which RGBD and Multisensor now share. Also from review: - odometry_mode_to_type matched modes by substring, so "notmultisensor" read as MSF. Strip the enum qualifier and look the mode up exactly. - The shuttle guard named only Inertial while process_imu covers every IMU-fusing mode, leaving multisensor rigs with an IMU free to replay measurements backwards. Both now use _IMU_FUSING_MODES. - A depth_sequence mixing .npy and image streams took the .npy scale for all of them. One scale covers every depth camera, so reject the mix instead. - A malformed depth_id or depth_scale_factor was warned about and then skipped or defaulted, silently dropping a depth camera or reading depth in raw units. Let the conversion raise; the callers already add the context.
