Description
Ashraf A A Beshr and co-authors present a 2026 study testing how accurate ground-based laser scanning is for watching buildings and structures shift over time. The scanners build dense 3D point clouds fast, but users need proof they can catch tiny moves, even when the tripod shakes. The team ran controlled tests against a high-precision survey tool.
The scanner spotted set moves with errors of roughly one to two millimetres against the reference tool. Shaking the tripod added distance errors of up to about four millimetres and angle shifts under some settings. A real case checked the tilt of a large oil storage tank in Egypt. The authors give practical limits for using scanning in structure health checks and fine surveying work.
