Schultz R. Theory and practice terrestrial laser scanning use in the tasks of engineering geodesy

In dissertation work theoretical generalization is executed and new theoretical and practical results are got concerning a decision scientifically of the applied problem of application of terrestrial laser scanning at the decision of tasks of engineering geodesy. The model of preliminary calculation of terrestrial laser scanningmethod accuracy built at implementation of static and mobile scanning. Classification of factors which influence on accuracy and quality of terrestrial laser scanningis conducted, that allowed to develop the single method of works planning on implementation of terrestrial laser scanning. The new universal mathematical model of terrestrial laser scanner calibration is developed on the base of neuron networks. The method of filtering of gross errors is developed with the use of wavelet-transformation. The new method of laser scan orientation is developed by the iteration method of closest point. For overcoming of problem of gross errors presence in terrestrial laser scanning data a RANSAC is used. The new method of creation of three-dimensional models is developed on the base of integration of TLS and digital photography data. As a result of the executed practical researches methods and technologies of application of terrestrial laser scanning are offered at the decision of engineer geodetic tasks.
