Method and device for generating panoramic slice map

Abstract

The embodiment of the invention discloses a method and device for generating a panoramic slice map, and the method comprises the steps: obtaining a spherical panoramic image; creating a spherical model in a virtual three-dimensional world according to the spherical panoramic image; pasting the spherical panoramic image on an inner spherical surface of the spherical model to obtain a spherical display view; obtaining a view image of the spherical display view, which takes the center of the spherical model as the center and is located in the direction of a target slice and within a preset view angle, as a panoramic slice map of the spherical panoramic image in the direction of the target slice. According to the scheme of the invention, the spherical panoramic image is pasted in the sphericalmodel, and the view image is obtained in one direction, thereby obtaining a slice map. The method is simple and convenient, and no additional software needs to be bought, thereby reducing the cost inobtaining the slice map.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and a device for generating a panoramic slice image. Background technique [0002] A spherical panorama can be compared to a map formed by rotating a semicircular fan with a fan perpendicular to the ground. Since the fan is a semicircular fan, it is 180 degrees in the vertical direction. Since the fan rotates once, It measures 360 degrees in the horizontal direction, that is, a spherical panorama is a picture that measures 360 degrees in the horizontal direction and 180 degrees in the vertical direction. The longitude and latitude of the spherical panorama are mapped to the flat network, and the north and south poles of the spherical panorama are stretched to the upper and lower edges to form a spherical panorama with an aspect ratio of 2:1. [0003] spherical panorama Figure 1 Generally, it is stored in various devices in a flat state (that is, a state with an aspect r...

AI Technical Summary

Problems solved by technology

In some cases, it is necessary to slice the flat spherical panorama to obtain a panoramic slice in a certain direction, which is a part of the spherical panorama. If the flat spherical panorama is directly intercepted, Then only some slices in the horizontal direction can be obtained, and slices in the vertical direction cannot be obtained. Moreover, since the flat image is obtained by stretching, the result obtained by directly intercepting the flat spherical panorama The image is a deformed image, and there will be a certain gap with the real image

Currently, it is only possible to slice spherical panoramas by purchasing some professional slicing clients to obtain panoramic slices that can feed back the real scene. The client does not disclose the technology for generating slices, and it is impossible to determine how these professional clients generate panorama slices
