Abstract

The invention provides a panoramic picture generating method. The method comprises the following steps: detecting a current viewing projection point of a user on a current panoramic picture at a first set time interval; obtaining a hotspot area closest to the current viewing projection point, and setting the hotspot area closest to the current viewing projection point an activated hotspot area; setting a picture resolution ratio of each area in the panoramic picture according to the activated hotspot area; generating a subsequent panoramic picture according to the picture resolution ratio of each area in the panoramic picture; and returning the step of detecting the current viewing projection point until the panoramic picture is completely played. The invention further provides a panoramic picture generating device. The picture resolution ratio of each area in the panoramic picture is set based on the activated hotspot area of the panoramic picture, thereby effectively reducing the bandwidth occupation of the panoramic picture on the basis of guaranteeing the picture display quality of the panoramic picture.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for generating a panoramic picture. Background technique [0002] With the development of science and technology, people have higher and higher requirements for visual images, so various virtual reality applications have been developed. [0003] Existing virtual reality applications generally have visual effects such as virtual reality (Virtual Reality) and augmented reality (Augmented Reality), and can realize panoramic visual images such as 3D panoramic video playback, 3D panoramic game experience, and 3D panoramic live broadcast. [0004] When a user views a panoramic image through a panoramic image acquisition device such as VR glasses, in order to meet the viewing requirements of the user in a 360-degree panoramic direction, the general panoramic image server will provide the VR glasses with a complete 360-degree panoramic image. However...
