Abstract

The invention provides a wireless microphone pickup distance determination method, device and equipment and a readable storage medium, and relates to the technical field of electronic information, and the method comprises the steps: obtaining first information and second information, the first information comprises at least one frame of historical image information obtained by a camera in a classroom, and the second information comprises at least one frame of historical image information; the second information is historical sound information collected by the wireless microphone; the first information is sent to an image processing module, third information is obtained, and the third information is information of the distance between the wireless microphone and the lips of the wireless microphone user; the second information is sent to a signal-to-noise ratio calculation module to obtain fourth information, and the fourth information is signal-to-noise ratio information of the wireless microphone; and determining the pickup distance of the wireless microphone based on the third information and the fourth information. According to the invention, image recognition and distance conversion are carried out on the historical image, so that the pickup distance of the wireless microphone can be quickly and accurately determined.

Description

technical field [0001] The present invention relates to the technical field of electronic information, and in particular, to a method, device, device and readable storage medium for determining the pickup distance of a wireless microphone. Background technique [0002] At present, there are various wireless microphones on the market, and everyone mainly focuses on the wireless transmission method as the research direction. Since wireless microphones are widely used in the teaching process of schools, equipment users and managers often use wireless microphones in this process. There will be some pain points. [0003] The sensitivity of wireless microphones on the market is relatively low, and the distance between the wireless microphone and the wireless microphone itself varies greatly depending on the distance between the sound point and the wireless microphone itself. Different, the employees of the company cannot hear clearly, and the voices recorded by many teachers in c...
