1. An audio acquisition device positioning method, comprising:
obtaining a first image that includes an audio acquisition device;
identifying the audio acquisition device in the first image;
obtaining first coordinate data of the identified audio acquisition device in the first image;
determining first displacement data according to a distance between coordinates indicated by the first coordinate data and coordinates indicated by historical coordinate data of the audio acquisition device stored in a historical coordinate database;
determining whether to store the first coordinate data in the historical coordinate database or a cache coordinate database according to a comparison of the first displacement data with a first threshold; and
determining, by processing circuitry, whether to copy data from the cache coordinate database to the historical coordinate database according to a comparison of the first coordinate data with second coordinate data of the audio acquisition device identified in a second image following the first image.
