Abstract

The present application provides a spherical image processing method, device and server. The present application relates to a spherical image processing method, comprising: obtaining a spherical image, and determining the center of the spherical image; determining the viewpoint of the user when watching the spherical image, and the viewpoint is located at any point in the spherical space surrounded by the spherical image except the center of the spherical image; Determine the pixel expansion area and pixel contraction area on the spherical image according to the center of the sphere and the viewpoint; perform image processing on the spherical image, and the image processing includes performing pixel expansion processing on the image in the pixel expansion area, and performing pixel contraction on the image in the pixel contraction area deal with. This application implements local zoom-in and local zoom-out according to the actual field of view of the viewpoint, so that users can obtain a movie-watching experience similar to that of objects actually viewed in the real world.

Description

technical field

[0001] The present application relates to image processing technology, in particular to a spherical image processing method, device and server. Background technique

[0002] In a virtual reality (Virtual Reality, referred to as: VR) panoramic video application, a user can watch a dynamic video at any angle of 360 degrees and enjoy a brand new viewing experience. Most of the existing panoramic video viewing methods use 3 degrees of freedom (3Degree of Freedom, referred to as: 3DOF) viewing experience. In this application, the viewpoint (including VR glasses, mobile phones, tablets, TVs, computers, etc.) The position of the center point of the sphere composed of the video can be used for viewing the panoramic video through arbitrary horizontal deflection, vertical pitch, and rotation around the axis. However, as people’s demand for a strong sense of immersion in VR gradually deepens, it is expected that the wearing point of view can move freely, front, back, l...
