Hilti x Trimble SLAM Challenge 2026: Is One Anchor Enough?

Voxel51’s FiftyOne Dataset Zoo now includes the Hilti x Trimble SLAM Challenge 2026, a floor-plan localization benchmark containing 30 construction-site runs across 10 floors and eight dates, captured with a consumer dual-fisheye 360 camera, IMU, LiDAR-inertial reference trajectories, and one measured starting pose in floor-plan coordinates. Using four repeat visits to one floor, the analysis applied a single rigid transformation to align each run’s initial local pose with its floor-plan anchor, then compared endpoint distance and symmetric chamfer distance across all six run pairs. Although the same-day pair ended only 1.05 meters apart versus a 5.9-meter cross-date average, its full-route chamfer distance of 4.30 meters was similar to the 4.01-meter cross-date average, showing that matching a single anchor or endpoint does not ensure that trajectories follow comparable paths. The results emphasize that single-anchor registration can establish a shared reference point but cannot correct route variation, odometric drift, or differing coverage, and recommend evaluating repeat visits with both endpoint and whole-path measures while reporting sample size. This approach is applicable beyond construction-site SLAM, including robotics, warehouse operations, and GPS-denied inspection environments where only one persistent landmark may be available.
