چکیده

Model fitting refers to problem that computing the most ideal parameters of a model so that the model gives the greatest extent of coincidence with the data. The most widely used method for fitting data with Gaussian noises should be ordinary least squares. However, the ordinary least squares method treats each datum equally, which makes it unsuitable for fitting the data containing outliers. Thus, a more robust method is needed this case (Szeliski 2010).

Automatic Segmentation of Building Facades Using Terrestrial Laser Data

There is an increasing interest of the scientific community in the generation of 3D facade models from terrestrial laser scanner (TLS) data. The segmentation of building facades is one of the essential tasks to be carried out in a 3D modelling process. Since in reality, majority of facade components are planar, the detection and segmentation of geometric elements like planes respond to the prev...

Outlier detection and robust normal-curvature estimation in mobile laser scanning 3D point cloud data

This paper proposes two robust statistical techniques for outlier detection and robust saliency features, such as surface normal and curvature, estimation in laser scanning 3D point cloud data. One is based on a robust z-score and the other uses a Mahalanobis type robust distance. The methods couple the ideas of point to plane orthogonal distance and local surface point consistency to get Maxim...

Generation of Roof Topologies Using Plane Fitting with Ransac

For the acquisition of Digital Surface Models (DSM), LIDAR has proven a reliable and accurate observation technique. In contrast to the generation of a Digital Terrain Model, which can be derived from the corresponding DSM by morphological filtering, the extraction of building models from the DSM requires more sophisticated modelling techniques. Here we follow a data-driven approach. The high d...

Diagnostic-robust Statistical Analysis for Local Surface Fitting in 3d Point Cloud Data

This paper investigates the problem of local surface reconstruction and best fitting for planar surfaces from unorganized 3D point cloud data. Least Squares (LS), its equivalent Principal Component Analysis (PCA) and RANSAC are the three most popular techniques for fitting planar surfaces to 3D data. LS and PCA are sensitive to outliers and do not give reliable and robust parameter estimation. ...

Levels of Detail in 3d Building Reconstruction from Lidar Data

3D models of buildings are useful for many applications such as urban planning and environmental simulation, cartography, tourism and mobile navigation. Automatically generating building models in the form of 3D CAD representation is the major part of city modeling and a challenge for many researchers. Airborne laser-scanning (ALS) results into high-quality geometrical information about the lan...
