Method, system, storage medium and device for quickly extracting horizon of three-dimensional scene

Abstract

The application discloses a three-dimensional scene skyline fast extraction method, system, storage medium and equipment, wherein the three-dimensional scene skyline fast extraction method comprises the following steps: 1, constructing a three-dimensional scene to be displayed, and loading image data and scene data; 2, performing edge detection on a scene graph displayed on a browser according to the depth value of a pixel, and extracting an edge pixel; 3, if the depth value of the pixel is greater than or equal to a preset sky area depth threshold value, the corresponding pixel is a sky pixel, otherwise, the pixel is a ground area pixel; 4, if the pixel on the scene graph displayed by the browser is both an edge pixel and a sky pixel, the pixel is set as an initial skyline pixel; and 5, performing local search on the initial skyline pixel to obtain a skyline in a two-dimensional display graph of a screen drawing area. The method does not depend on ground object information in the three-dimensional scene, has no complex calculation, and can quickly extract the skyline in the scene.
