| Summary: | As built surveying is a survey technique where position and geometrical attributes are observed and presented in a survey plan. Three- dimensional reconstruction from geoinformation discipline has the advantage to improve the measurement of an as built building. Modern as built reconstruction has less limitation compared to conventional as built surveying. The objective of this study is to validate the accuracy of point cloud measurement and traditional as built data. Terrestrial laser scanner was used to record all interior and exterior spatial and geometry data of a building. A rendered 3D model of the scanned data was developed to provide semantic information of the building. The result shows that geometrical measurement of an as built model from point cloud data has good accuracy. As conclusion, the point cloud data is suitable to be used for as- built reconstruction which improves as-built surveying practice. |
