METHOD AND SYSTEM OF AUTOMATIC CONSTRUCTING THREE-DIMENSIONAL MODELS OF CITIES

摘要

FIELD: information technology.;SUBSTANCE: method of automatic constructing three-dimensional models of cities based on the processing of data from various sources, in particular laser scanning and photographic data, the formation of a single point cloud, the cleaning of a given point cloud, the sequential identification of urban objects, the construction of three-dimensional models of identified objects and their subsequent integration for constructing a single three-dimensional model of the city.;EFFECT: increasing the accuracy of constructing a three-dimensional model of the city by providing the construction of a city model based on separately recognized urban objects derived from previously cleaned laser scanning data.;13 cl, 9 dwg
