As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. When the phrase "at least one of" is preceded by a list of components, the entire list of elements is modified instead of the individual elements in the list.

Please refer to FIG. 1 and FIG. 2 , which are respectively a block diagram of a first embodiment of the emotion detection system according to the present invention and a schematic diagram of the captured target human body image. As shown in FIG. 1 , the emotion detection system 1 of the present invention includes an image capturing device 102, a physiological signal detecting device 104, a processing module 106, a current signal database 108, a physiological signal determining module 110, and an emotion.

And a calorie detecting device. The physiological signal detecting device 104 can be configured to obtain a plurality of physiological signals of the target human body, such as a heart rate signal, a blood pressure signal, a respiratory signal, a body temperature signal, an infrared signal, and a calorie change signal.

The processing module 106 is electrically connected to the image capturing device 102 and the physiological signal detecting device 104. The processing module 106 can be a central processing unit configured to analyze the acquired target human body image, thereby obtaining the target human body. A facial feature signal and a plurality of body characteristic signals. The non-contact detection method is mainly used. The facial feature signal can include facial features, eye features, relative position of the eyeball, eyebrows and mouth changes, and body characteristic signals can include changes in organs such as the shoulders, chest, and limbs. Type. Specifically, the processing module 106 first determines the face and body position according to the target human body image, and then analyzes a plurality of facial features and a plurality of physical features according to the image of the face position and the body position. The manner in which the processing module 106 is configured to analyze the target human body image to obtain a plurality of facial features and a plurality of physical features of the target human body may be implemented by a hardware or software (for example, being executed by the central processing unit and stored in the emotion detection system). The code or application in the storage unit or the firmware that can implement the above analysis is not specifically limited.

For example, facial features may include detection of various facial expression muscles, such as Auricularis anterior muscle, Buccinator muscle, eyebrow reduction muscle, Depressor anguli oris muscle, lowering lip Depressor labii inferioris muscle, Depressor septi nasi muscle, frontal muscle, Levator anguli oris muscle, Levator labii superioris muscle, Mentalis muscle, nasal muscle Orbicularis oculi muscle, orbicularis oculi muscle, platysma, Procerus muscle, laughter muscle, Zygomaticus major muscle, Zygomaticus minor muscle, and the like.

And correlating the facial feature signal, the physical characteristic signal and the physiological signal with the target human body to establish a personalized physiological signal model PSM. For example, when the emotion detection system 1 first detects the emotion of the new target human body, since the reference reference for determining the emotion has not been established, it is necessary to perform modeling for the target human body for a period of time in order to subsequently determine the emotion of the target human body. The current signal database 108 can be stored in the storage unit built in the emotion detection system 1, such as memory, volatile memory, dynamic random access memory, static random access memory, non-volatile memory, Regularized read-only memory, erasable programmable read-only memory, electronically erased rewritable read-only memory, flash memory, disk, hard disk, floppy disk or tape, etc. The database mentioned in the text can be stored in the above hardware, and is not limited to the above hardware, and can be stored in any device capable of realizing data storage.

Among them, the optical flow method is actually a method of inferring the moving speed and direction of an object by detecting the change of the intensity of the pixel of the image with time. Optical flow methods have been widely used in pattern recognition, computer vision, and other image processing applications. They can be used for motion detection, object cutting, collision time and object expansion calculations, motion compensation coding, or stereoscopic surfaces and edges. Measurement, etc.

The emotion determination module 112 can be electrically connected to the emotion rule table 118 configured to compare the emotion rule database 114 according to the plurality of physiological state change results 116, and generate an emotion comparison result 120, and the emotion rule table 118 is pre- The definition has a correspondence between a plurality of physiological state change results and a plurality of emotional comparison results.

For example, the emotional rules table may include at least the following correspondence: emotional normal corresponds to all data normal; emotional fatigue corresponds to yawning, increased breathing depth, abnormal blink frequency, and excessive blinking time; emotional panic corresponds to increased heart rate, Increased respiratory rate and large eyes; emotional stress corresponds to increased heart rate, increased respiratory rate, and positional changes in multiple facial features less than a predetermined amount of change; and emotional excitement corresponds to increased heart rate, increased respiratory rate, and increased calorie expenditure . The normal data is that the change of the plurality of facial feature signals, the plurality of physical characteristic signals, and the plurality of physiological signals does not exceed the set normal set error value relative to the previously established personalized physiological signal model PSM. For example, the respiratory rate, heart rate, respiratory depth, and facial features are all within 5% of the normal state, which can be regarded as normal data. As for the position change amount of the plurality of facial features being less than the predetermined amount of change, it can be regarded as a tight expression.

An example of how the emotion detection system 1 operates. Referring to FIG. 2, the processing module 106 is configured to analyze the target human body image IMG to obtain the target human body face position FACE and the body position BODY, and further detect the driver's eye area EYE, nose area NOSE, and mouth. Area MOUTH, eyebrow area BROW, chest area CHEST, and carotid area VES. The processing module 106 is configured to set the face position FACE and the body position BODY within a predetermined time, and further detect the driver's eye area EYE, the nose area NOSE, the mouth area MOUTH, the eyebrow area BROW, and the chest area CHEST. And the size, shape or vertical variation of the VES in the carotid region, generating a plurality of signals corresponding to the information, stored in the current signal database 108, and correlating the signals with the target human body to establish a personalized physiology Signal model PSM.

Then, the processing module 106 is configured to obtain a plurality of facial feature signals and a plurality of physical feature signals of the target human body. The physiological signal determination module 110 is configured to compare the plurality of facial feature signals, the plurality of physical characteristic signals, and the plurality of physiological signals in the time point interval to the personalized physiological signal model PSM, for example, according to the eye region. The EYE, the nose region NOSE, the mouth region MOUTH, the eyebrow region BROW, the chest region CHEST, and the carotid region VES generate a plurality of physiological state change results 116 corresponding to changes in the facial feature signal and the body characteristic signal.

The emotion determination module 112 compares the emotion rule table 118 stored by the emotion rule database 114 according to the plurality of physiological state change results 116, and generates an emotion comparison result 120. For example, when a person detects that a person's heartbeat suddenly accelerates, the breath suddenly accelerates, the eyes are wide, and other information may indicate that someone may be suddenly scared, and when someone is detected to have yawning, deep breathing, abnormal blink frequency, etc. Representing someone has a great chance of fatigue.

Specifically, for example, when the emotion detection system 1 is used in the driving state, the processing module 104 is configured to detect the target human body eye area EYE, and can analyze the driver through the instant target human driving behavior image. Driving for fatigue and lack of concentration. For example, the physiological signal determination module 110 is configured to detect the eyeball position, the blink time, and the blink frequency of the eye region EYE. If the eyeball position cannot be detected, the driver may fall asleep; if the blink time or the blink frequency is abnormal, Determine the driver's lack of concentration. The blinking time and the blinking frequency anomaly mean that the driver can drive the driver to fatigue driving every time the blinking time is too long (the driver blinks) and the blinking frequency is too high.

In this system, in addition to enabling non-contact emotion detection, which is more acceptable to the average user, the system also uses personalized data modeling and analysis, and integrates multiple physiological information, which can be used in a unified data model. The emotion detection method more accurately determines the physiological state of the target human body.

However, in the early stage of system detection, due to the insufficient amount of information collected on facial feature signals, body characteristic signals and multiple physiological signals, personal historical statistics and parental statistics may be used to temporarily replace insufficient information to establish Part of the characteristic signal data of the personalized physiological signal model.

Please refer to FIG. 3, which is a block diagram of a second embodiment of the emotion detection system according to the present invention.

The difference in the emotion detection system 1 is that the current signal database 108 further includes personal historical physiological signal data 122 and parent statistical physiological signal data 124. The personal historical physiological signal data 122 may include historical data of all facial facial signals, physical characteristic signals, and physiological signals of the target human body, and may be stored in the form of personalized physiological signal models at different time points. In addition, the maternal statistical physiological signal data 124 may include historical data of facial feature signals, body characteristic signals, and physiological signals counted by all, and may be optionally selected for region, time zone, latitude and longitude, time point, race, or skin color. Classification to sample the highest similarity for the target's information when the system is accessed.

Specifically, the processing module 106 can be further configured to store a plurality of facial features, a plurality of physical features, and a plurality of physiological signals and historical signal data stored in the historical signal database and the parent statistical physiological signal in a predetermined time period. The data is integrated to produce a personalized physiological signal model PSM. Here, the so-called integration involves the use of average statistical methods such as arithmetic mean, geometric mean, harmonic mean, squared average, moving average, or substitution, replacement data, etc. to introduce historical physiological signal data and maternal statistical physiological signal data into personalized physiological signals. In the modeling step, it is not limited to this.

Therefore, by integrating historical physiological signal data and maternal statistical physiological signal data, the defects of insufficient information can be compensated in the early stage of system detection, and the accuracy of emotion detection can be further improved during and after system detection.

At the application level, the emotion detection system can be implemented in the form of an application of a smart mobile device and executed by its processor. Preferably, the image capturing device 102 can adopt the camera of the smart phone, and the physiological signal detecting device 104 can adopt the smart wearing device linked with the smart mobile device to minimize the inconvenience caused by the contact detecting device. To enhance the flexibility of this system implementation. For example, in this way, the risk of a car accident can be reduced when driving, and by analyzing the driver's emotion, it can be directly determined whether the driver is fatigue driving or drunk driving, and an immediate alarm is issued when the driver is in a bad state. Reduce the risk of car accidents.

In addition, this emotion detection system can also be used to reduce the security angle. For example, you can use the surveillance video machine network to find people with bad moods, take the initiative to care ahead, and reduce the security risks. In addition, it can also be applied to airports and customs inspections, by quickly finding people with abnormal emotions to reduce the possibility of carrying illegal customs clearance or potential violence.
