FMCW-LIO introduces a novel LiDAR‑inertial odometry framework that exploits the Doppler velocity measurements provided by Frequency Modulated Continuous Wave (FMCW) Doppler LiDARs. By incorporating a motion compensation scheme and a Doppler‑aided observation model, the method effectively removes dynamic points and enhances geometric consistency. Experiments across diverse scenes demonstrate that FMCW‑LIO delivers more accurate state estimation and robust static mapping, outperforming existing algorithms in both accuracy and resilience.

The paper introduces TempLoc, a Temporal‑aware Localization framework that improves outdoor LiDAR relocalization by leveraging spatio‑temporal consistency across scans. It first predicts point‑wise global coordinates with uncertainties, then estimates inter‑frame correspondences using an attention‑based Prior Coordinate Generation module, and finally fuses these predictions in an uncertainty‑guided manner to produce a more accurate global 6‑DoF pose. Experiments on the NCLT and Oxford RobotCar datasets show that TempLoc significantly outperforms existing state‑of‑the‑art methods.

DAVIO is a dense monocular‑inertial SLAM system that leverages a single multi‑view depth model (Depth Anything 3) for both initialization and mapping. It starts up quickly by solving a feature‑free linear system from a five‑image window and IMU pre‑integration, then uses a VIO filter whose metric poses condition the depth model during tracking. The system corrects residual scale along viewing rays, preserves metric baselines, and refines the map with a gravity‑preserving sub‑map graph, achieving earlier start‑up, lower localization error, and more accurate dense maps than state‑of‑the‑art feed‑forward mappers on both EuRoC and building‑scale ORI datasets.

ALS boresight calibration has relied for two decades on dedicated flight patterns over structured scenes containing planar surfaces of varied aspect and slope. While reliable, this approach imposes constraints on the scene content and operations, which limits its applicability to boresight recovery within routine mapping missions.

Autonomous navigation of quadrupedal robots in diverse environments fundamentally relies on resilient Simultaneous Localization and Mapping (SLAM). While visual-inertial SLAM has matured across wheeled, handheld, and aerial platforms, a critical evaluation gap remains regarding how hardware-level sensor configurations affect performance under the aggressive dynamics of legged locomotion.
arXiv:2601. 03040v2 Announce Type: replace-cross Abstract: A fundamental requirement for full autonomy is the ability to sustain accurate navigation in the absence of external data, such as GNSS signals or visual information.

The paper introduces SLIM-init, a monocular visual‑inertial initialization method that avoids explicit 3D reconstruction by using 2D line features and vanishing points. It provides robust rotation constraints through line‑derived vanishing points and improves translation estimation with a line epipolar residual and a line‑normal projection residual. Experiments on public benchmarks and custom degenerate‑motion sequences show that SLIM-init achieves higher accuracy and robustness than existing initialization techniques.
