Abstract

The invention discloses a spherical panoramic image processing method, device, server and system. The method comprises the steps of: determining a rectangular pyramid, wherein the bottom surface of the rectangular pyramid is a square; and the side surface of the rectangular pyramid is an equilateral triangle; establishing a three-dimensional coordinate system comprising the rectangular pyramid, and putting the sphere centre of the inscribed sphere of the rectangular pyramid in the origin of the three-dimensional coordinate system, wherein the front of the rectangular pyramid is parallel to thefirst coordinate plane in the three-dimensional coordinate system; determining coordinates of points on various surfaces of the rectangular pyramid in the three-dimensional coordinate system; according to the coordinate of each point of the rectangular pyramid, calculating the longitudes and latitudes of pixel points correspondingly on a spherical panoramic image, and establishing the corresponding relationship of the points on the rectangular pyramid and the pixel points on the spherical panoramic image, wherein the centre of the front of the rectangular pyramid corresponds to the centre ofthe spherical panoramic image; and mapping the pixel points on the spherical panoramic image to the corresponding points on the rectangular pyramid, so that the panoramic image of the rectangular pyramid is obtained. By means of the technical scheme disclosed by the invention, the data size of the panoramic image can be effectively reduced; the code rate of the panoramic image when network transmission is carried out can be greatly reduced; and in addition, requirements on the network bandwidth can be reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a spherical panorama processing method, device, server and system. Background technique [0002] With the rapid development of Internet VR technology, the demand for panoramic images is also increasing. Panoramic images are 360-degree content, and generally have a relatively high bit rate, which puts a lot of pressure on network transmission. And more often people may pay attention to a certain part of the panoramic image, such as the part that people pay attention to on the stage in a concert, the part that people pay attention to when playing in a sports event, and so on. Therefore, the bit rate can be reduced as much as possible while ensuring the image quality at a certain angle. Contents of the invention [0003] A technical problem to be solved by the embodiments of the present invention is that the bit rate of the spherical panorama transmitted in the network ...
