Abstract

The present invention relates to the technical field of image processing, and the present invention provides an image generation method and system based on oblique grid data. The two-dimensional grid of the inclined grid data is divided into blocks, the large area of ​​data corresponding to the large-scale picture is divided into multiple small areas, and the picture data corresponding to the small areas is loaded in sequence; The data association relationship of a large area is spliced ​​to the picture data corresponding to the small area to obtain a large-scale image. The invention can effectively reduce the amount of data read through the two-dimensional grid division of the inclined grid data and the conversion and splicing of the small area data, which not only realizes the rapid loading of large-scale images, but also improves the output quality. Image quality for large scale images.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image generation method and system based on oblique grid data. Background technique [0002] With the rapid development of oblique photography technology, the amount of data processed by oblique grid data continues to increase. There has always been a need for global viewing of skewed mesh data, so images from specific perspectives have become a display alternative to the full model. On the other hand, fixed-view images are also in considerable demand in the fields of data analysis, mapping, and surveying. [0003] However, when the slanted grid data tiles are too large, these data tiles cannot be loaded and displayed to the finest level of Lod (level of detail) at the same time, so a large-scale image cannot be loaded. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide an image generation method and system based on oblique g...
