Description
Technical field
A kind of harvester is the utility model is related to, more particularly to a kind of round-the-clock face harvester, belongs to safety and recognizes
Card technology, biometrics identification technology field.
Background technology
It is existing in the art, biometrics identification technology be listed in 21 century human society is brought it is revolutionary influence ten
One of big technology.Biometrics identification technology is presently the most the identity recognizing technology of convenient safety, biometrics identification technology
It is to carry out identification using the physiological characteristic and behavioural characteristic of people, mainly there is fingerprint recognition, recognition of face, iris recognition etc..
Wherein, recognition of face is a big focus in current biological feature recognition field.It is with the fingerprint identification technology being widely used at present
Compare, there are the distinguishing features such as compare intuitive, convenience, untouchable, user's acceptance is high.
The single imaging method of traditional face harvester generally use, i.e. face visible light reflection imaging or infrared
Line source actively irradiates face catoptric imaging one kind therein.What wherein face visible ray was got is colored facial image,
These images contain abundant human face expression, physiological characteristic, and this has a great extension for the application of recognition of face, but visible ray
Imaging is had a great influence by ambient light, and the power of ambient light directly influences the effect of face imaging, particularly ambient light
In the case that line is bad, the effect of imaging is undesirable；Although infrared light sources actively irradiate face catoptric imaging imaging effect compared with
It is good, but infrared ray active light source is in infrared filter, has filtered out natural light, only allows infrared light to carry out camera, so as to
To be black and white image, simultaneously because always on infrared light supply, the power consumption of equipment can be increased.Both modes respectively have excellent lack
Point, use range is restricted, therefore, we have proposed a kind of round-the-clock face harvester.
Utility model content
Main purpose of the present utility model is to provide a kind of round-the-clock face harvester, detected by ambient light single
The setting of member, the illumination of ambient light is detected, by the light illumination detected compared with preset value, to be automatically adjusted to picture
Mode, when light illumination is more than preset value, using face visible light reflection imaging；When light illumination is less than preset value,
Light filling is carried out using infrared light sources.High-quality face is obtained by taking different imaging modes under different illumination conditions
Image so that the data collected are more effective, while reduce the power consumption of equipment, can effectively solve asking in background technology
Topic.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of round-the-clock face harvester, including ambient light detecting unit, infrared lamp source, imaging sensor, control
Unit, display screen, host CPU, optical filter rotating mechanism and power module processed, the ambient light detecting unit, imaging sensor,
Control unit and display screen are electrical connected with host CPU, and the optical filter rotating mechanism and infrared lamp source are and control unit
It is electrical connected.
Further, the optical filter rotating mechanism is made up of cutoff filter, all-pass eyeglass and electric rotating machine.
Further, the ambient light detecting unit, infrared lamp source, imaging sensor, control unit, display screen,
Host CPU and optical filter rotating mechanism are connected with electric line with power module.
Compared with prior art, the utility model has the advantages that：A kind of round-the-clock face harvester, passes through
The setting of ambient light detecting unit, the illumination of ambient light is detected, by the light illumination detected compared with preset value,
To be automatically adjusted to the mode of picture, due to the setting of optical filter rotating mechanism, when light illumination is more than preset value, electric rotating machine
All-pass eyeglass is changed, using face visible light reflection imaging；When light illumination is less than preset value, electric rotating machine changes infrared section
Only optical filter, light filling is carried out using infrared light sources.Obtained by taking different imaging modes under different illumination conditions
High-quality facial image so that the data collected are more effective, while also farthest reduce the power consumption of equipment, whole dress
Put practical, collection effect is good, and energy consumption is low, is adapted to be widely popularized.

Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in Figure 1-2, a kind of round-the-clock face harvester, including ambient light detecting unit 1, infrared lamp source 2,
Imaging sensor 3, control unit 4, display screen 5, host CPU 6, optical filter rotating mechanism 7 and power module 8, the ambient light
Detecting unit 1, imaging sensor 3, control unit 4 and display screen 5 are electrical connected with host CPU 6, the optical filter rotating mechanism
7 and infrared lamp source 2 be electrical connected with control unit 4.
Wherein, the optical filter rotating mechanism 7 is made up of cutoff filter 9, all-pass eyeglass 10 and electric rotating machine 11.
