The variance inflation factor to account for correlations in likelihood ratio tests: deformation analysis with terrestrial laser scanners

Measurement of Structural Deformation using Terrestrial Laser Scanners

Three deformation measurement experiments have been undertaken where, in each experiment, a structure was subject to controlled loading. Terrestrial laser scanners (TLSs) were used to make measurements at critical intervals during each load test. TLSs, which are a relatively recent innovation, are capable of rapidly capturing thousands of three dimensional points over the surface of an object. ...

Likelihood Ratio Tests in Multivariate Variance Components Models

ii Acknowledgements In preparing this thesis I am indebted to many people. First of all, I wish to express my sincere gratitude to Professor Chihiro Hirotsu, my thesis supervisor, for his guidance and encouragement. Komaki for their valuable comments and suggestions. Finally I am very grateful to my parents for their continual encouragement, and to my wife, Hisae, who has shared both my joy and...

A Resolution Measure for Terrestrial Laser Scanners

Terrestrial laser scanners are increasingly being used for cultural heritage recording and engineering applications that demand high spatial resolution. Knowledge of an instrument’s spatial resolution is necessary in order to prevent aliasing and estimate the level of detail that can be resolved from a scanned point cloud. In the context of laser scanners, spatial resolution can be decoupled in...

Urban 3d Modelling Using Terrestrial Laser Scanners

This paper describes a technique for 3D Reconstruction of large outdoor areas using terrestrial laser scanning. It presents the paradigm for automated 3D registration and requirements of the positioning and orientation subsystem to handle fully automatic 3D registrations. It analyzes the different problems and difficulties associated with such type of environments, including the analysis of sca...
