Reflected light.Specifically, when eyes of user receives infrared light, according to infrared light human body eye high reflection principle,
Eyes can reflect infrared light, that is, send infrared external reflection light, further, and infrared collecting module 130 receives infrared external reflection light,
And infrared external reflection light is identified.
In specific example, infrared collecting device 130 is, for example, infrared camera, and it is used for assisted face identification, and to people
Body eye infrared external reflection light is identified.
Processing module 140 is connected with image capture module 110 and infrared collecting module 130 respectively, for the face according to user
Portion's image and infrared external reflection light determine the eye locations of user, and judge whether user pays close attention to mesh according to the intensity of infrared external reflection light
Mark region.Specifically, processing module 140 is used to, when the intensity of infrared external reflection light is more than or equal to predetermined threshold value, judge to use
Target area is paid close attention at family, and when the intensity of infrared external reflection light is less than predetermined threshold value, judges that user does not pay close attention to target area.
The cardinal principle of the sight identifying device 100 of the embodiment of the present invention is summarized as：By infrared collecting module 130 and infrared light
Source 120 is arranged in target area, and the mounting distance of the two is nearer, when the eyeball of identified user faces target area
When within certain limit, user eyeground and iris are very strong to infrared reflection degree, are preset when the intensity of infrared external reflection light exceedes
During threshold value, judge that user pays close attention to and (watched attentively) target area, and when the intensity of infrared external reflection light is less than predetermined threshold value,
Judge that user does not pay close attention to and (watched attentively) target area.
Further, in one embodiment of the invention, the number of infrared light supply 120 for example can be multiple, Duo Gehong
Outer light source 120 runs on one plane.Based on this, processing module 140 is additionally operable to it is determined that the eye position of identified user
After putting, the eyes image of user is obtained, and partial enlargement is carried out to the eyes image of user, to the red of user eyeball surface
External reflectance optical mode is identified, to judge user's sight being specifically directed towards in target area.
In addition, in one embodiment of the invention, processing module 140 is additionally operable to the infrared of continuous identification user eyeball surface
Light reflection mode, to identify the moving direction of user's sight.
Further, in one embodiment of the invention, processing module 140 is additionally operable to record user's concern target area
Duration, so as to judge the degree of concern of user.
To sum up, sight identifying device according to embodiments of the present invention, determines to use according to the face-image of user and infrared external reflection light
The eye locations at family, and when the intensity of infrared external reflection light is more than or equal to predetermined threshold value, judge user's concern target area,
And when the intensity of infrared external reflection light is less than predetermined threshold value, judge that user does not pay close attention to target area.Therefore, the device can
Accurately identify the sight region-of-interest of user and be specifically directed towards, and time and the moving direction of sight concern can be counted.
Further embodiment of the present invention also proposed a kind of sight recognition methods.
Fig. 2 is the flow chart of sight recognition methods according to an embodiment of the invention.As shown in Fig. 2 this method include with
Lower step：
Step S1：Gather the face-image of user.In specific example, for example, visible ray figure is shot by visible image capturing head
Picture, for face recognition to obtain the face-image of user.
Step S2：Infrared light supply is provided in target area, and receives in target area the infrared external reflection from eyes of user
Light.Specifically, infrared light supply outwards launches the infrared light of some strength, when eyes of user receives infrared light, according to
Infrared light is in the high reflection principle of human body eye, and eyes can reflect infrared light, that is, send infrared external reflection light, further, example
Infrared external reflection light is such as received by infrared camera, and infrared external reflection light is identified.
Step S3：The eye locations of user are determined according to the face-image of user and infrared external reflection light, and according to infrared external reflection light
Intensity judge whether user pays close attention to target area.Specifically, if the intensity of infrared external reflection light is more than or equal to default threshold
Value, then judge user's concern target area；If the intensity of infrared external reflection light is less than predetermined threshold value, judge that user does not pay close attention to
Target area.
The cardinal principle of the sight recognition methods of the embodiment of the present invention is summarized as：For example, it will be seen that light video camera head and infrared light supply
It is arranged in target area, and the mounting distance of the two is nearer, when the eyeball of identified user faces the certain model in target area
When within enclosing, user eyeground and iris are very strong to infrared reflection degree, when the intensity of infrared external reflection light exceedes predetermined threshold value,
Judge that user pays close attention to and (watched attentively) target area, and when the intensity of infrared external reflection light is less than predetermined threshold value, judge user
Do not pay close attention to (watching attentively) target area.
Further, in one embodiment of the invention, the individual position of infrared light supply for example can be multiple, multiple infrared lights
Source distribution is in a plane.Based on this, this method also includes：It is determined that after the eye locations of identified user, obtaining
The eyes image of user, and partial enlargement is carried out to the eyes image of user, to the infrared external reflection optical mode on user eyeball surface
It is identified, to judge user's sight being specifically directed towards in target area.
In addition, in one embodiment of the invention, this method also includes：The infrared reflecting on continuous identification user eyeball surface
Pattern, to identify the moving direction of user's sight.
Further, in one embodiment of the invention, this method also includes：The duration that user pays close attention to target area is recorded,
So as to judge the degree of concern of user.
To sum up, sight recognition methods according to embodiments of the present invention, determines to use according to the face-image of user and infrared external reflection light
The eye locations at family, and when the intensity of infrared external reflection light is more than or equal to predetermined threshold value, judge user's concern target area,
And when the intensity of infrared external reflection light is less than predetermined threshold value, judge that user does not pay close attention to target area.Therefore, this method can
Accurately identify the sight region-of-interest of user and be specifically directed towards, and time and the moving direction of sight concern can be counted.
