Embodiment
The core devices of human face recognition machine is 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 face identification device on a large scale that the utility model provides, its ultimate principle is by adopting two or more imageing sensors, obtain respectively the user's of different heights face image information 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 by reference to the accompanying drawings.
Embodiment one:
As shown in Figure 2, the imageing sensor for the utility model face identification device arranges view.Face identification device shown in Figure 2 comprises two imageing sensors, is respectively the first imageing sensor 1 and the second imageing sensor 2.The first imageing sensor 1 is arranged at the second imageing sensor 2 tops, and two imageing sensors have certain angle in the axial direction.
Two effective visual angles that imageing sensor forms, as shown in dotted line as outermost in 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 to gather image information, can greatly reduce the restriction to user's height, to collect comparatively satisfied image information.In order to reach wider effect on the basis accurately, described the first imageing sensor and the second imageing sensor axially between angle be between 0～90 degree.
Adopt the described scheme of the present embodiment, enlarged effective visual angle of imageing sensor, therefore, the user need not just can collect image information smoothly by the stance adjustment of up and down, left and right, and is very convenient.
When the user adopts the described face identification device of the 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 the first imageing sensor and the second imageing sensor form, two sensors carry out respectively coarse scanning fast, obtain user's height and face location information; Then, the information such as the integrity degree of the image information that obtains according to two above-mentioned imageing sensors and sharpness, to collect satisfactory imageing sensor as the imageing sensor of preferentially selecting, and adopt this imageing sensor to carry out close scanning, obtain more face image information and process, so just can obtain optimum recognition of face effect.
In addition, face identification device in this embodiment also comprises power supply, described power supply is lithium ion battery, and this power supply also has for the display device of the dump energy that shows lithium ion battery and is used for working as the dump energy of lithium ion battery lower than the warning device of certain value alarm.
Embodiment two:
the present embodiment and embodiment one difference are, increased the 3rd imageing sensor, make described face identification device have three imageing sensors: the first imageing sensor 1, the 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 the second imageing sensor 2 and horizontal direction parallel, it is interior (for example: user 160cm-175cm) that apparent field's scope of the second imageing sensor 2 covers normal height scope as far as possible, to guarantee that the second imageing sensor 2 can accurately collect the human face image information of user in normal height scope.
The axial direction of the first imageing sensor 1 and the second imageing sensor 2 has certain angle, and the axial direction of the 3rd imageing sensor 3 and the second imageing sensor 2 also has certain angle, three formed effective angulars field of view of imageing sensor are as shown in dotted line as outermost in 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 to gather image information, can greatly reduce the restriction to user's height, to collect comparatively satisfied image information.
Further, the axial direction angle between described the first imageing sensor 1 and the second imageing sensor 2 is between 1～45 degree; Axial direction angle between the 3rd imageing sensor 3 and the 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 the second imageing sensor 2 at an angle with horizontal direction, the scope of its angle is can be between 1～45 degree, cover user in normal height scope with the effective angular field of view that guarantees the second imageing sensor 2, collect human face image information accurately.
Embodiment two compares with embodiment one, although be provided with an imageing sensor, but can increase effective visual angle of image information collecting more, has further reduced the restriction to user's height, has optimized the experience of face identification device.
In the present embodiment, the image acquisition process of three imageing sensors and embodiment one are basic identical, when the user enters in effective angular field of view of three imageing sensors, three sensors carry out respectively coarse scanning fast, obtain user's height and face location information; Then, the information such as the integrity degree of the image information that obtains according to three above-mentioned imageing sensors and sharpness, to collect the imageing sensor of satisfactory image information as the imageing sensor of preferentially selecting, and adopt this imageing sensor to carry out close scanning, obtain more face image information and process, so just can obtain optimum recognition of face effect.
In addition, face identification device in this embodiment also comprises power supply, described power supply is lithium ion battery, and this power supply also has for the display device of the dump energy that shows lithium ion battery and is used for working as the dump energy of lithium ion battery lower than the warning device of certain value alarm.
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 image information comprehensively and efficiently; 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, reduce the restriction to user's height, optimized the experience of face identification device.
The utility model described embodiment is only preferred embodiment, but its meaning and unrestricted scope of the present utility model, applicability and configuration.On the contrary, to the detailed description of embodiment, those skilled in the art are implemented.Will be understood that not departing from the definite the utility model spirit and scope situation of appended claims, can make suitable change and modification to some details.
