The ancient architecture is mostly built by adopting wood materials, and more or less damages, sedimentation and collapse exist after time precipitation, and especially, repair protection is needed and effectively carried out in time under the condition of structural damage. Because of the irreproducibility and vulnerability of ancient architecture, the repair work needs to be very accurate and careful, a plurality of important key node geographic coordinates of the structural architecture are obtained by using a modern technology, and the repair scheme is simulated by constructing a building information model (Building Information Modeling), that is, adopting an advanced BIM technology to precede the model, and finally, the scheme is knocked out again, so that the rework is avoided as much as possible. Before repair, each key node of the building needs to be measured, and effective data support is provided for the building information model so as to purposefully carry out repair scheme design.
