Embodiment
The core devices of recognition of face machine is an imageing sensor, and the size of its effective angular field of view is directly connected to the processing in obtaining of image information and later stage.
A kind of wide-angle face identification device that the utility model provides, its ultimate principle is by adopting two or more imageing sensors, obtain the user's of different heights face image information respectively from different angles, thereby enlarge the angular field of view of image acquisition, to reach the effect of accurate identification.
Below by describing in detail with specific embodiment in conjunction with the accompanying drawings.
As shown in Figure 2, the imageing sensor for the utility model face identification device is provided with view.Face identification device shown in Figure 2 comprises two imageing sensors, is respectively first imageing sensor 1 and second imageing sensor 2.First imageing sensor 1 is arranged at second imageing sensor, 2 tops, and two imageing sensors have certain included angle in the axial direction.
Two effective visual angles that imageing sensor forms, shown in the outermost dotted line of Fig. 2, as seen, effective visual angle of two imageing sensor formation is greater than effective visual angle of an imageing sensor, thereby, when the user uses face identification device images acquired information, can significantly reduce restriction, to collect comparatively satisfied image information to user's height.In order to reach wider effect on the basis accurately, the axial direction angle of described first imageing sensor and second imageing sensor is between 0 ~ 90 degree.
Adopt the described scheme of present embodiment, enlarged effective visual angle of imageing sensor, therefore, about the user need not pass through, about stance adjustment, just can collect image information smoothly, very convenient.
When the user adopts the described face identification device of present embodiment to carry out the human face image information collection, the image acquisition process of two imageing sensors is as follows: in the time of in the user enters into effective angular field of view that first imageing sensor and second imageing sensor form, two sensors carry out coarse scanning fast respectively, obtain user's height and face location information; Then, according to information such as the integrity degree of the above-mentioned image information that two imageing sensors obtained and sharpness, to collect satisfactory imageing sensor as the imageing sensor of preferentially selecting for use, and adopt this imageing sensor to carry out close scanning, obtain more face image information and handle, so just can obtain optimum recognition of face effect.
Embodiment two:
Present embodiment and embodiment one difference are, increased by one the 3rd imageing sensor, make described face identification device have three imageing sensors: first imageing sensor 1, second imageing sensor 2 and the 3rd imageing sensor 3, as shown in Figure 3, wherein, the housing 4 of face identification device is perpendicular to horizontal direction, the axial direction of second imageing sensor 2 and horizontal direction parallel, apparent field's scope of second imageing sensor 2 covers as far as possible in the normal height scope that (for example: user 160cm-175cm) can accurately collect face images of users information in the normal height scope to guarantee second imageing sensor 2.
The axial direction of first imageing sensor 1 and second imageing sensor 2 has certain angle, and the axial direction of the 3rd imageing sensor 3 and second imageing sensor 2 also has certain angle, three formed effective angulars field of view of imageing sensor are shown in the outermost dotted line of Fig. 3.Hence one can see that, effective visual angle of adopting three imageing sensors to form is greater than effective visual angle of an imageing sensor, thereby, when the user uses face identification device images acquired information, can significantly reduce restriction, to collect comparatively satisfied image information to user's height.
Further, the axial direction angle between described first imageing sensor 1 and second imageing sensor 2 is between 1～45 degree; Axial direction angle between the 3rd imageing sensor 3 and second imageing sensor 2 is between 1～45 degree.
In embodiment two, when the housing 4 of face identification device with horizontal direction at an angle the time, can make second imageing sensor 2 be certain angle with horizontal direction, the scope of its angle is can be between 1～45 degree, cover user in the normal height scope with the effective angular field of view that guarantees second imageing sensor 2, collect human face image information accurately.
Embodiment two compares with embodiment one, though be provided with an imageing sensor, but can increase effective visual angle that image information is gathered more, has further reduced the restriction to user's height, has optimized the experience of face identification device.
The image acquisition process of three imageing sensors and embodiment one are basic identical in the present embodiment, when the user enters in effective angular field of view of three imageing sensors, three sensors carry out coarse scanning fast respectively, obtain user's height and face location information; Then, according to information such as the integrity degree of the above-mentioned image information that three imageing sensors obtained and sharpness, to collect the imageing sensor of satisfactory image information as the imageing sensor of preferentially selecting for use, and adopt this imageing sensor to carry out close scanning, obtain more face image information and handle, so just can obtain optimum recognition of face effect.
Advantage of the present utility model and effect are: gather human face image information by adopting two or more imageing sensors, can enlarge effective angular field of view of image acquisition, thereby obtain effective comprehensively and efficiently image information; User for different heights, as long as the user enters in effective angular field of view of imageing sensor formation, just can collect accurately and comprehensively people's face information, and not need to carry out the attitude adjustment, reduced restriction, optimized the experience of face identification device user's height.
Embodiment that the utility model is described only is preferred embodiment, but its meaning and unrestricted scope of the present utility model, applicability and configuration.On the contrary, the detailed description to embodiment can make those skilled in the art be implemented.Will be understood that not departing under the definite the utility model spirit and scope situation of appended claims, can make suitable change and modification some details.
