Embodiment 1

[0023] Such as figure 1 As shown, a smart speaker control method based on gesture recognition, including:

[0024] Set several different command states;

[0025] Set the same gesture action to represent different speaker control commands in different command states;

[0026] Obtain the gesture recognition result, and convert the gesture recognition result into a control command in combination with the current command state;

[0027] The control command is sent to the speaker control device to control the speaker.

[0028] This embodiment specifically includes:

[0029] Set two different command states of 0 and 1, and switch the command state by triple-clicking the gesture, and set the status indicator to indicate the current state;

[0030] When the status is 0, the gesture push is converted into a speaker control command for lowering the volume, and the gesture pull is converted into a speaker control command for increasing the volume;

[0031] When it is in state 1, the...

Embodiment 2

[0070] Such as figure 2 As shown, a smart speaker control system based on gesture recognition, including

[0071] A gesture recognition device, a main control processor and a speaker control device, the main control processor is respectively connected with the gesture recognition device and the speaker control device, and the gesture recognition device is used to recognize gesture actions and send the recognition result to the main control processor , the main control processor receives the gesture recognition result, judges whether to switch the instruction state according to the received result, and converts the gesture recognition result into a control instruction according to the current instruction state, and sends it to the speaker control device, and the speaker control device is used for Control speakers.

[0072] The gesture recognition device recognizes various gestures of the user and transmits the recognition results to the main control processor. The main contro...

Embodiment 3

[0110] Such as image 3 As shown, a smart speaker control system based on gesture recognition includes an interconnected gesture recognition device, a main control processor and a speaker control device, and the gesture recognition device is used to recognize gestures and send the recognition results to the main control processor , the main control processor generates a control instruction according to the received gesture recognition result and sends it to the speaker control device to realize the control of the speaker; the gesture recognition device includes a signal transmitting module, a signal receiving module and a signal preprocessing connected in sequence module, also includes the attribute feature vector extraction module connected with the signal preprocessing module, the attribute feature vector extraction module is connected to the Chebyshev forward neural network classifier, and the signal transmission module is used to transmit ultrasonic signals, and the signal ...

Abstract

The invention discloses an intelligent loudspeaker box control method based on gesture recognition. The method comprises the steps of setting several different kinds of command states; setting a same gesture action to represent different loudspeaker box control commands under different command states; acquiring a gesture recognition result, and converting the gesture recognition result into a control command through combining with the current command state; and sending the control command to the loudspeaker box control device to achieve the control on the loudspeaker box. Also disclosed is an intelligent loudspeaker box control system based on gesture recognition, the loudspeaker box control system comprises a gesture recognition device, a master control processor and a loudspeaker box control device. According to the method and system, the several different kinds of command states are set, thus the same gesture action is converted into different operations on the loudspeaker box under the different command states, the reuse of the simple gesture action is achieved, the ultrasonic signal is used as a gesture action detection and recognition carrier, the risk that the privacy of the user is leaked can be effectively avoided, meanwhile the signal processing complexity is smaller, fewer resources are required, and the recognition rate is also improved.

Description

technical field [0001] The invention relates to the field of smart speaker control, in particular to a gesture recognition-based smart speaker control method and system. Background technique [0002] With the development of audio signal processing technology and wireless communication technology, speakers have gradually moved from the earliest pure analog output equipment to digital, integrated and intelligent. In this era of vigorous development of smart hardware, smart speakers are also emerging in an endless stream. An important difference between smart speakers and traditional speakers is that smart speakers usually use wireless communication methods such as wifi or bluetooth to obtain media files from playback sources (usually computers and smart phones, etc.), and then perform audio decoding, filtering, amplification and other operations until Complete the output. Traditional speakers usually use audio cables to receive analog audio signals from playback sources, and...
