Description
Technical field
The present invention relates to camera mounts, and in particular to the face identification device with stabilization dust-separation function.
Background technology
The English name of recognition of face is that Human Face Recognition. face recognition products utilize AVS03A images
Processor；Face light and shade can be detected, the compensation of adjust automatically dynamic exposure, face tracking detecting, adjust automatically image zoom.
The practical recognition of face of broad sense includes a series of the relevant technologies for building face identification system, including man face image acquiring, face
Positioning, recognition of face pretreatment, identity validation and identity finder etc.；And the recognition of face of narrow sense refers in particular to carry out body by face
Part confirms or the technology or system of identity finder.
The scene of real name is needed at some large-scale activities scene or similar library etc., frequently with the mode conduct of recognition of face
Into the safety check means of place, but everyone height is different, and the existing camera mount for recognition of face is more
For fixing bracket, if encounter the people that height differs greatly with ordinary people, it is also necessary to the height of camera mount is adjusted manually, this
It is not only troublesome, also result in the reduction of recognition of face safety check efficiency.
In addition, existing video camera is generally included there are one flash lamp, which is located at the top of video camera, so its
Polishing is uneven, and excessively close apart from the photosensitive end of video camera；When being shot at night, it is usually susceptible to exposure dead angle or appearance
Large stretch of overexposure area influences video camera recognition of face effect.
Invention content
It is an object of the invention to overcome the above technical problem, the face identification device with stabilization dust-separation function is provided,
With can reduce exposure dead angle or overexposure area according to the height of everyone height automatic adjusting support, recognition of face can be improved
The function of safety check efficiency.
The present invention is achieved through the following technical solutions：
Face identification device with stabilization dust-separation function, including video camera body, mounting platform, rack body, installation are flat
Platform bottom is fixed with rack body, and the mounting platform is rectangular box, and the video camera body is located in rectangular box, in rectangular box
Several light compensating lamps are evenly arranged on open end, be additionally provided at the top of rectangular box interconnection solar panel and
Accumulator is connect after the light compensating lamp series connection with accumulator；The rack body includes the hydraulic stem being connected with each other, hydraulic-driven
System, top and the rectangular box bottom end of the hydraulic stem are fixed, and further include controller, the mark post parallel with hydraulic stem, in mark post
Its axial direction of upper edge is provided with three groups of ultrasonic sensing and pops one's head in, transfer tube in all ultrasonic sensing probes, fluid power system
Motor connect respectively with controller by conducting wire, when three groups of ultrasonic sensing probe while when sensing human body, the hydraulic pressure
Bar rises；When two groups of ultrasonic sensing positioned at mark post lower end are popped one's head in while sensing human body, the hydraulic stem remains stationary as；
When the ultrasonic sensing probe positioned at mark post least significant end senses human body, the hydraulic stem declines.
The present invention is improved existing holder, and improvement is as follows：1, it is directed to the problem, the present invention will in the prior art
Plate mounting platform be designed as rectangular box, video camera is placed in rectangular box, and on the end face of rectangular box uniformly
Multiple light compensating lamps are set, which can play protection video camera, dustproof effect, also form an annular light filling for video camera
Circle so that when shooting at night, captured image is more clear video camera, helps to reduce exposure dead angle or overexposure area.And
And the present invention is provided with the solar panel and accumulator of interconnection at the top of rectangular box, is received using solar panel
Collect solar energy, and convert the solar into the light compensating lamp power supply that power storage is all in accumulator so that light compensating lamp makes

As camera mount, mechanical-stretching bar in the prior art is substituted, can be driven hydraulic stem using fluid power system lifts；
Simultaneously increase with ultrasonic sensing probe mark post structure, ultrasonic sensing probe induction human body mode be all it is existing,
And the direction of the launch of ultrasonic sensing probe and the photosurface of video camera are located at the same side, due to three groups of ultrasonic wave senses on mark post
The height that should be popped one's head in is different, so when people is in face of video camera, some ultrasonic sensing probe can sense human body information, have
A bit cannot, this shows that everyone height is different.So the present invention utilizes the principle, controller in the prior art is distinguished
It is connect with ultrasonic sensing probe and motor, according to the signal for receiving different ultrasonic sensing probes, to drive on hydraulic stem
It rises or declines, a kind of mounting bracket that can control camera mount automatic controlled height according to the height of tested person is realized with this
Purpose, solve when encountering the people that height and ordinary people differ greatly in the prior art, need to adjust camera mount manually
Height, this is not only troublesome, also result in recognition of face safety check efficiency reduce the problem of.
Bottom is provided with damping base in rectangular box, and the video camera body is located at damping base upper surface.Further,
A damping base is arranged in video camera body bottom in the present invention, can alleviate the concussion that video camera body is subject to when entire holder is collided
Power can reduce flating degree when video camera body shooting.
Preferably, the damping base includes support tablet, four stabilizer blades, one end and the support planar bottom surface of each stabilizer blade
Corner fix, the other end and nitrogen silica-gel sphere are fixed, the part surface of the nitrogen silica-gel sphere is embedded in rectangular box inner bottom surface
In.Damping base in the prior art generally uses spring structure, and spring, which only has axial damping function and is easily deformed, to be lost, and is made
It is shorter with the service life.So the present invention has redesigned a kind of new shock-damping structure, using nitrogen silica-gel sphere as damping matrix, ball
Body structure have arcwall face, whether by concussion axially or radially when, can along cambered surface by stress shake point dispersion, damping
Effect is good, compared with prior art, can greatly improve camera lens stabilization ability.
It is additionally provided with tumbler pedestal in hydraulic stem bottom, the mark post is fixed with the upper surface of tumbler pedestal simultaneously.
The present invention utilizes the balance and stability characteristic of tumbler self structure, as pedestal, it is ensured that the stability of whole device is kept away
Exempt to fall down the problem of damaging video camera.
Compared with prior art, the present invention having the following advantages and advantages：
1, the present invention has the face identification device of stabilization dust-separation function, is improved to mounting platform, forms annular ring,
So that video camera, when shooting at night, captured image is more clear, help to reduce exposure dead angle or overexposure area, and mend
Light lamp has the advantages that the cable not by power supply area is limited, is stabilization, dust-proof when in use, can move entire photographic device everywhere
Dynamic, environmental protection is practical；
2, the present invention has the face identification device of stabilization dust-separation function, can control video camera according to the height of tested person
The purpose of the mounting bracket of holder automatic controlled height solves and encounters the people that height differs greatly with ordinary people in the prior art
When, the height for adjusting camera mount manually is needed, this is not only troublesome, also results in the problem of recognition of face safety check efficiency reduces,
With extraordinary market application prospect.
