Creation method of body weight acoustic measurement model, body weight measuring method, creation device of body weight acoustic measurement model, and body weight acoustic measuring device

Abstract

The embodiment of the invention provides a creation method of a body weight acoustic measurement model, a body weight measuring method, a creation device of the body weight acoustic measurement model,and a body weight acoustic measuring device. The creation method of the body weight acoustic measurement model comprises the following steps of calculating acoustic feature parameters of animal audiodata, wherein the acoustic feature parameters include the sound pressure, the peak value frequency, the frequency spectrum centriod and the power spectrum; obtaining the real body weight of an animalowning the audio data; creating the weight acoustic measurement model; and training the weight acoustic measurement model by using the acoustic feature parameters of the animal audio data and the real body weight of the animal owning the audio data to obtain a body weight estimated parameter value in the body weight acoustic measurement model. The creation method of the body weight acoustic measurement model, the body weight measuring method, the creation device of the body weight acoustic measurement model, and the body weight acoustic measuring device provided by the embodiment of the invention have the advantages that the body weight of the animal can be estimated through sound; firm foundation is provided for real-time fast low-cost and non-contact measurement of the body weight of the animal; and wide application prospects are realized.
