Extraction of significant data and data reduction are desired in the 3D measurement of existing buildings. In this research, two methods were applied to interpolate and thin out the point clouds. One is the weighted least squares method which can create a surface that is not affected by outliers. The other is the simple shape extraction method using principal component analysis. This method is suitable for point clouds of directional members such as columns.
