Abstract

The invention relates to the field of massive urban space three-dimensional data cloud rendering, in particular to a massive urban space three-dimensional data cloud rendering image fusion method anda massive urban space three-dimensional data cloud rendering image fusion system. The method is characterized by comprising the following steps of: S1, acquiring image data to be fused; S2, judging the number of images; S3, carrying out CPU image fusion; S4, carrying out GPU image fusion; and S5, completing the image fusion. According to the invention, the fusion efficiency of multiple images canbe greatly improved, and the rendering performance of a three-dimensional large-scale scene is further improved.

Description

technical field [0001] The invention relates to the field of cloud rendering of massive urban space three-dimensional data, in particular to a method and system for fusion of massive urban space three-dimensional data cloud rendering images. Background technique [0002] High-precision, high-resolution three-dimensional data extraction of urban space is the key to "smart cities" and "digital cities". Due to the lack of means, the urban three-dimensional spatial data is leaping exponentially. [0003] The three-dimensional data of urban space mainly includes the data obtained by combining two-dimensional maps and architectural design drawings, digital photogrammetry, laser scanning systems, high-resolution satellite remote sensing, and vehicle-mounted mobile surveying and mapping systems. The combination of two-dimensional maps and architectural design drawings refers to the combination of map data that can meet the contour accuracy requirements and building planning and des...
