USE OF BORDERLINES IN URBAN 3D-MODELING

摘要

A method for generating a 3D-model of an urban environment including: identifying a first plurality of border lines where each border line substantially circumferences a sub -area within the urban environment; generating a 3D-model for the urban sub -areas; generating a 3D-model for an complementary area of the urban environment, the complementary area the border lines and the area between the border lines and excluding the urban sub-areas; merging the 3D-models of the sub-areas with the 3D-model of the complementary area to form said 3D-model of the urban environment.
