Abstract
A background audio construction method is provided. The background audio construction method includes: performing semantic segmentation on to-be-processed video data to generate a corresponding semantic segmentation map, and extracting a semantic segmentation feature of the to-be-processed video data based on the semantic segmentation map; extracting an audio feature of each audio file in a pre-established audio set; and aligning the audio feature and the semantic segmentation feature, selecting a target audio file from the audio set based on an alignment result, and constructing background audio for the to-be-processed video data based on the target audio file.
