The flowchart for the deformed shape monitoring model proposed in this paper is shown in Figure 3.
As shown in Figure 3, the deformed shape monitoring model based on a 2D scanner consists of the
following five modules: (1) module for acquiring coordinate information of a point in a building;
(2) module for coordinate transformation and data arrangement for generation of time history of the
point; (3) module for smoothing by adjacent averaging technique; (4) module for generation of the
displacement history for each story and deformed shape of a building, and (5) module for evaluation of
the serviceability of a building.
