Description
Technical field
The utility model relates to field of face identification, more particularly to a kind of face recognition device with automatic covering tabula rasa.
Background technique
Camera is the core component of face recognition device.At work, recognition effect is easy by strong shadow camera
It rings, causes face recognition accuracy rate to decline, or even can not identify.
It is at present typically all to be blocked using physical means, i.e., by imaging to enable camera to cope with strong illumination
Increase a hood on head to achieve the purpose that block strong light (referring to figure 1 and figure 2).This process needs manpower complete
At, including artificially judge opportunity, artificially increase hood, the shading range of the artificial hood of adjustment in real time is artificial to remove and receive
It receives hood, therefore generally requires special messenger to safeguard hood, not only use very inconvenient, but also be difficult accurate judgement
Hood uses opportunity.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of face recognition device with automatic covering tabula rasa, it can be with
Shading range and shading amount are automatically adjusted according to environmental light intensity.
In order to solve the above technical problems, the face recognition device with automatic covering tabula rasa of the utility model, including equipment sheet
Body and barn door are integrated with master controller, camera and motor in the apparatus body, and the master controller is taken the photograph with described respectively
As head and electrical connection of motor；The barn door is flexibly connected with the apparatus body, and with the electrical connection of motor.
It can be flexibly connected using hinge arrangement between the barn door and the apparatus body.
The barn door is preferably two folding barn doors, can be using hinge arrangement activity between two parts of barn door
Connection.
The slewing area of hinge arrangement is preferably 180.
The barn door can also be using structures such as folding, winding or slidings.
A light sensor can also be integrated inside the apparatus body, be electrically connected, be used for the master controller
Incude environment light intensity.
The motor can select small-sized steering machine.
The utility model utilizes the shading appearance of motor control barn door by the way that barn door is arranged on face recognition device
State enables barn door that the variation of ambient light to be followed to adjust shading posture in real time, automatically controls the light quantity for entering camera, so
The convenience used is not only increased, special messenger's maintenance is not needed, and it is accurate to ensure that shading opportunity and shading range judge
Efficiently, whole process realizes unmanned, automation and intelligence.

Specific embodiment
There is more specific understanding for technology contents, feature and effect to the utility model, it is now in conjunction with attached drawing and specifically real
Example is applied, the technical solution of the utility model is further described in detail.
The structure of the face recognition device with automatic covering tabula rasa of the present embodiment is as shown in figure 3, mainly include apparatus body 3
With barn door 4.
Master controller, camera 31 and small-sized steering machine are integrated in the apparatus body 3.The camera 31 is for passing through
Camera shooting acquisition face information, and induction environment light intensity.The steering engine is used to adjust the shading posture of the barn door 4.
The master controller is electrically connected with the camera 31 and steering engine respectively, is mainly used for communication connection, processing data and intelligence
Control.
The barn door 4 is connected to the top of the apparatus body 3 by articulate, for blocking ambient light, adjusts
Section enters the light quantity of camera 31.In the present embodiment, which is two folding structures, uses hinge between two parts
Structure movement connection.The slewing area of two hinges of barn door 4 is 180.
The steering engine 33 is electrically connected with the barn door 4, for controlling two hinge arrangements of the barn door 4, with
Adjust the shading posture of barn door 4.
The principle and working method of above-mentioned face recognition device are described in detail below.
When ambient light is darker, barn door 4 is collapsed at 3 top of apparatus body, as shown in Figure 3.
When ambient light is stronger, camera 31 senses that light-inletting quantity increases, and light amount information is transmitted to master controller.When taking the photograph
When reaching preset threshold value as first 31 light-inletting quantity, master controller is issued to steering engine and is instructed, and steering engine drives on barn door 4
Barn door 4 is opened in hinge rotation, and with the variation in the visual field of camera 31 and light-inletting quantity, adjusts the shading of barn door 4 in real time
Posture, as shown in figure 4, the shading range of control barn door 4, to guarantee camera shooting under the premise of not influencing 31 visual field of camera
First 31 recognition effect.
Work as dimming, when the light-inletting quantity of camera 31 is lower than preset threshold value, master controller refers to steering engine sending
It enables, steering engine controls barn door 4 and folds gathering, as shown in Figure 3.
The above is only a possible embodiments of the utility model.In other embodiments, barn door can also use
The structures such as folding, winding or sliding.Small-sized steering machine can also be replaced using other kinds of motor (such as stepper motor).This
Outside, it can also be internally integrated a light sensor in apparatus body, is electrically connected with the main control module, for incuding environment light
The brightness of line, and the light signal received is converted into electric signal transmission to master controller, to control the shading posture of barn door.
