Abstract:
1. A construction progress visualization system, comprising: a computer aided design (CAD) model storage unit for storing a three-dimensional (3D) CAD model of a construction object; a construction schedule storage unit for storing construction schedule data; a scaffolding model creating-unit for creating an area and a form of scaffolding required for a construction operation based on the 3D CAD model and the construction schedule data; a scaffolding schedule extracting-unit for extracting scaffolding schedule data regarding the scaffolding from the construction schedule data in the construction schedule storage unit; a scaffolding display form determining-unit for determining a completion rate of the scaffolding on a visualization-target date based on a relationship between the visualization-target date and the scaffolding schedule data, and obtaining a display form of the scaffolding; and a display process unit for generating display information of the CAD model, and display information of the scaffolding area based on the obtained display form of the scaffolding, wherein the scaffolding model creating-unit has a first processing-unit for dividing a construction-object space in a height direction based on a scaffolding standard height to create a plurality of layers, and further dividing each of the layers into a plurality of mesh cells based on a scaffolding width, a second processing-unit for setting at least one of the mesh cells and at least one other mesh cell below the at least one of the mesh cells as the scaffolding areas when the CAD model exists above or adjacent to and no CAD model exists below each of the mesh cells, and a third processing-unit for creating a scaffolding model for the mesh cells determined as the scaffolding area.
