Abstract

The invention provides a spherical image processing method and device and a server. The spherical image processing method comprises the following steps: acquiring a spherical image, and determining the sphere center of the spherical image; determining a viewpoint when the user watches the spherical image, wherein the viewpoint is located at any point except the sphere center in a sphere space surrounded by the spherical image; determining a pixel expansion area and a pixel contraction area on the spherical image according to the sphere center and the viewpoint; and performing image processingon the spherical image, wherein the image processing comprises performing pixel expansion processing on the image in the pixel expansion region and performing pixel contraction processing on the imagein the pixel contraction region. According to the invention, local enlargement and local reduction are carried out according to the actual view of the viewpoint, so that the user can obtain the viewing experience similar to the near-to-far small-zoom change of the object 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...
