Abstract

The invention provides an automatic modeling method based satellite images, and relates to the technical field of automatic modeling. The method comprises the following steps: acquiring image parameters of a to-be-modeled object acquired by a satellite, wherein the image parameters comprise at least one of the satellite data of a three-dimensional image pair and the satellite data of multi-image pairs; cutting the obtained image parameters to obtain texture images; modeling the to-be-modeled object based on an inclined three-dimensional modeling method and the texture images, and obtaining a target model of the to-be-modeled object; attaching the texture image correspondingly to the target model, and obtaining a model of the to-be-modeled object. The method solves the technical problems oflong modeling period and high modeling cost in the existing three-dimensional automatic modeling technology, so that the technical effects of low cost and short-period modeling are achieved.

Description

technical field [0001] The invention relates to the technical field of automatic modeling, in particular to a method for automatic modeling based on satellite images. Background technique [0002] With the rapid development of geographic information technology and Internet technology, all walks of life have put forward high requirements for the intuitiveness and authenticity of information display, and the research on 3D model construction technology has attracted more and more attention. At present, the methods of 3D modeling mainly include: manual modeling and automatic modeling based on aerial images. [0003] The two existing 3D modeling methods described above still have quite a lot of shortcomings in terms of model construction: first, when the traditional artificial modeling method is used for modeling, the texture of the upper part and top surface of the building obtained is relatively small. Less, and the traditional manual modeling method relies on manual modeling...
