Abstract

The invention discloses a decoration event detection method and device, a computer device and a medium. The method comprises the sound is collected by a microphone or a microphone array in real time to obtain the to-be-detected sound information; acoustic characteristics of the sound information are extracted; a ResCNN neural network model is constructed; the acoustic characteristics are inputtedinto the ResCNN neural network model to obtain the decoration sound probability p; the acoustic probability p is compared with the actual result, and a cross entropy loss function is constructed; theResCNN neural network model is trained according to the cross entropy loss function; the trained ResCNN neural network model is utilized to perform decoration sound prediction, if the sound is determined to be the decoration sound, the location where a decoration event occurs is identified based on the device number of the microphone. The method is advantaged in that whether decoration occurs andidentification of the decoration location can be effectively determined, through combining the ResCNN neural network architecture and the cross entropy loss function, not only the decoration sound identification rate is improved, but also whether a certain sound is the decoration sound can be accurately identified, and the overall model size is reduced.

Description

technical field

[0001] The invention relates to the field of decoration, in particular to a decoration event detection method, device, computer equipment and media. Background technique

[0002] Building a good home life, decoration is one of the important links. People hire a decoration company to decorate the house according to their own preferences, and decorate it into a style they like, so as to improve the beauty of the house and the comfort of their own living. However, the renovation will affect the rest of the neighbors at the same time, resulting in many quarrels due to community renovations. In order to avoid this situation from happening again, many communities now have clearly stipulated time periods for house renovation, but not all decoration companies will carry out renovations according to the time specified by the community. The rest of the residents near the floor. In order to prevent improper decoration behaviors from disturbing the residents, it is ne...

Embodiment Construction

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The first embodiment of the present invention provides a method for detecting decoration events, as shown in the attached figure 1 shown, including the following steps:

[0040] Step 1, collecting sound in real time through a microphone or a microphone array to obtain sound information to be detected;

[0041] Step 2, extracting the acoustic features of the sound information from the sound information; the process of extracting the acoustic features of the sound information includes converting the time-domain signal into time-frequency domain in...
