Abstract	本发明公开了一种基于视口特征的边缘缓存置换方法，包括以下步骤：获取全景视频中各图块的权重信息；当需要对获取的图块进行缓存时，判断所述边缘缓存的存储空间是否充足；若所述边缘缓存的存储空间不足，删除所述缓存单元中小于预设权重的图块；根据置换算法对存储所述图块的缓存单元进行置换；所述边缘缓存通过创建缓存单元存储同一全景视频的图块。本发明还公开了一种边缘缓存装置及计算机可读存储介质，解决了现有技术中无法判断图块重要性导致边缘缓存的图块命中率降低的问题，提高边缘缓存图块命中率。
Other Abstract	The invention discloses an edge cache replacement method based on viewport characteristics. The method comprises the following steps: obtaining weight information of each image block in a panoramic video; when the acquired image blocks need to be cached, judging whether the storage space of the edge cache is sufficient or not; if the storage space of the edge cache is insufficient, deleting the image blocks smaller than a preset weight in the cache unit; and replacing the cache unit storing the image blocks according to a replacement algorithm, wherein the edge cache stores the image blocks ofthe same panoramic video by creating the cache unit. The invention further discloses an edge caching device and a computer readable storage medium, the problem that the block hit rate of edge cachingis reduced due to the fact that the block importance cannot be judged in the prior art is solved, and the edge caching block hit rate is increased.
