Currently, the process of conservation by digitizing historic buildings is a key technology in cultural heritage preservation that needs further improvement. However, a comprehensive survey of projects of digital archives shows that traditional, time-consuming construction methods were adopted most, as in taking pictures or cartographing physical buildings through AutoCAD to construct digital data. This study adopted reverse engineering to explore digitalizing constructions and employed a fast and precise 3-D laser scanner to retrieve point cloud data and then import the data into Rapidform XOR2, an application used in reverse engineering, to process point cloud data and construct 3-D models.
