Embodiment Construction

[0051] The present invention provides a method and device for detecting baby's emotions based on brain waves. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] see figure 1 , figure 1 It is a flow chart of a preferred embodiment of the brain wave-based infant emotion detection method provided by the present invention. As shown in the figure, the electric infant emotion detection method includes the following steps:

[0053] Step S100, collecting brain wave signals at multiple positions in the baby's brain, where multiple electrodes can be placed by the international 10-20 system electrode placement method to collect the brain wave signals...

Abstract

The invention discloses an infant emotion detection method and device based on brain waves. According to the infant emotion detection method, brain wave signals are acquired at a plurality of positions of the brain of an infant; the acquired brain wave signals are processed, and a first energy ratio and a second energy ratio are calculated according to energy of the brain wave signals acquired at all the positions and energy of signals in preset frequency bands; the first energy ratio and the second energy ratio are matched in a prestored emotion sample library to obtain a final sample, so that corresponding infant emotion information is obtained. The infant emotion detection method and device based on brain waves realize real-time judgment of emotions of the infant through the brain waves, enable emotion judgment of the infant to be more accurate, and bring much convenience to a user.

Description

technical field [0001] The present invention relates to the field of brain wave detection, in particular to a method and device for detecting baby emotion based on brain waves. Background technique [0002] There are only two ways for babies to communicate with the outside world after birth and before they learn to speak. This is generally called the baby's language. Especially when crying, babies often have to express many meanings, but parents of newborns often Unable to cope when the baby cries because he does not understand the meaning of the cry. Can only rely on experience to deal with. In the prior art, Brown University in the United States and Rhode Island Women and Children's Hospital jointly produced a set of algorithms for cracking babies' cries, matching audio, tone, volume, etc. to judge the meaning of babies' cries, but each baby produced The tone and volume of the baby are different, and the interference of the audio from the outside world also has a corresp...
