VFM-SDM: A vision foundation model-based framework for training-free, marker-free, and calibration-free structural displacement measurement

ArXi:2605.09677v1 Announce Type: new Reliable displacement measurement is fundamental for structural health monitoring and digital engineering workflows, as it provides direct structural response information. Vision-based measurement has emerged as a promising approach for low-cost, non-contact displacement monitoring. However, its deployment often remains constrained by task-specific model
