Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
Because the motion detection in the prior art does not consider the interference caused by the self-vibration of the electronic equipment, the detection rate of the motion detection is influenced. In view of this, the present invention provides a motion characteristic detection method for an electronic device. Fig. 1 is a flowchart of a motion characteristic detection method for an electronic device according to an embodiment of the present invention. As shown in fig. 1, the motion characteristic detection method of the present invention may include the steps of:
and S10, acquiring the audio signal sent by the electronic equipment.
And S20, acquiring the motion signal acquired by the motion detection device. The motion signal includes a motion component of the electronic device and a self-vibration interference component generated by the audio signal due to the audio signal emitted by the electronic device. In some embodiments, the electronic device may be any electronic device capable of emitting audio signals and capable of motion detection in any suitable manner. In some embodiments, the electronic device is a speaker.
And S30, filtering self-vibration interference components generated by the audio signals from the motion signals according to the acquired audio signals, thereby extracting the motion components.
According to the technical scheme, the self-vibration interference component caused by the audio signal is filtered from the motion signal, so that the self-vibration of the electronic equipment can be filtered while the motion gesture is detected, the detection rate of the motion detection on the equipment can be greatly improved for the equipment capable of causing the self-vibration by the audio signal, and the user motion detection function can be favorably supported on the equipment with the self-vibration.
Fig. 2 is a block diagram of a motion characteristic detection apparatus for an electronic device according to an embodiment of the present invention. Referring to fig. 1 and 2, the motion feature detection apparatus of the present invention may include an audio acquisition module 50, a motion detection device 51, and a self-vibration filtering module 52. The audio obtaining module 50 may be configured to execute step S10 to obtain an audio signal sent by the electronic device. The motion detection device 51 may be used to perform step S20 to acquire a motion signal. The self-vibration filtering module 52 may be configured to execute step S30 to filter the self-vibration interference component from the motion signal according to the acquired audio signal, so as to extract the motion component. In one embodiment, the motion detection device 51 may be a motion sensor.
Fig. 3 is a flowchart of a motion characteristic detection method for an electronic device according to another embodiment of the present invention. As shown in fig. 2 and fig. 3, in this embodiment, step S10 may specifically include S101, and at S101, the frequency domain signal of the audio and the signal gain representing the audio volume may be acquired by the audio acquisition module 50.
Step S20 may specifically include S201. At step S201, a motion signal may be acquired by the motion detection device 51 (e.g., a motion sensor). Step S202 may also be performed after step S201, and the motion signal acquired by the motion detection device 51 may be subjected to filtering processing at S202 by the filtering module 53 connected between the motion detection device 51 and the self-vibration filtering module 52.
Then, proceeding to step S30, the self-vibration interference component may be filtered out by the self-vibration filtering module 52. Specifically, the self-vibration interference component may be determined according to the frequency domain signal and the signal gain of the audio obtained in step S101, and the self-vibration interference component may be filtered from the motion signal, so as to extract the motion component of the electronic device. In some embodiments, the mapping relationship between different frequency domain signals and signal gains and the self-seismic interference components that can be generated by the frequency domain signals and the signal gains may be predetermined, and a table lookup method or the like may be used to determine the self-seismic interference components corresponding to the obtained frequency domain signals and signal gains. In other embodiments, any implementable manner may be employed to determine the self-seismic interference component of the audio signal.
As shown in fig. 2 and 3, the motion feature detection method of the present invention may further include step S40, where at S40, the extracted motion component may be matched with the motion feature by the motion matching module 54. The extracted motion component can be matched with a plurality of preset motion templates by comparing, and the plurality of motion templates can respectively correspond to different motion gesture recognition results, so that when the extracted motion component is matched with one preset motion template, the motion gesture recognition result corresponding to the motion component can be determined. In one embodiment, the motion template comprises a motion template of a manual rocking portable loudspeaker, and when the extracted motion component matches the motion template, the motion gesture recognition result may be determined to be the manual rocking portable loudspeaker. In other embodiments, other suitable configurations for the motion template may be used.
Then, when it is judged at S50 that the extracted motion component matches the motion feature, a corresponding motion posture recognition result is output through the result output module 55; when it is judged that the extracted motion component does not match the motion feature, the process returns to step S20.
After obtaining the detected motion gesture recognition result, the motion feature detection method of the present invention may further include step S60, determining whether the motion gesture recognition result meets a condition for executing a preset operation through a preset operation module (not shown), and if so, executing a corresponding preset operation; if not, the process returns to step S20. Fig. 3 shows, without limitation, a case where the preset operation is a shutdown operation, that is, shutdown is performed if the detected moving posture recognition result reaches a condition for performing the shutdown operation. In other embodiments, the preset operation may be any suitable configuration. In other embodiments, the detected motion gesture recognition results may be used to execute an appropriate application.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
