It can not solve the problems, such as distance light killer, intelligent sunshading board is attempted to solve this problem.Representative in terms of intelligent sunshading board is Liaoning
The liquid crystal sun shield of golden ocean photoelectricity, it can be according to the transparency of the light intensity adjust automatically sunshading board of Chinese herbaceous peony.However it
The disadvantage is that whole discoloration, simultaneously because having used one group of polaroid, causes highest light transmittance less than 45%, so can not be at night
It uses.
Also there are the technology for the control light penetration for not needing polaroid very much, such as polymer dispersed liquid crystals at this stage
(PDLC), micro- shutter (micro blinds), electrochromism etc., they can be by voltage, the drive of electrostatic or electric current
The dynamic light control for realizing pixel scale.For example, CN201710007610 refers to carry out the poly- of voltage driving by tft array
The equipment for closing object dispersed LCD to control light.US7684105 refers to micro- shutter (micro blinds) of electrostatic drive
The equipment for controlling light.CN201210499579 puts forward the active matrix display device based on electrochromic material.
Depth perception module, such as depth camera can also obtain shooting pair other than it can obtain flat image
The depth information of elephant, that is, three-dimensional positions and dimensions information, so that entire computing system obtains the three-dimensional of environment and object
Stereo data.With the progress of automatic Pilot technology, the perception of depth information and calculate can be with being realized with a low cost.Now
Popular depth perception technology has structure light, the flight time (Time of Flight, one of basic technology of laser radar), double
Visually feel or even multi-vision visual, there are also light field depth perception technologies etc..Many automobile main frame maker all realize binocular vision now

It calibrates and is easy.When detecting the 3 D stereo position of pupil, it is contemplated that interior possible light is than darker, based on knot
The realization of structure light is preferentially considered as.It is also contemplated that active light filling when insufficient light, in favor of capturing pupil or eyes
Position, such as infrared laser (such as 905nm wavelength) Lai Zhaoming of supplement infrared light or eye-safe, neither influence driver
Vision is also conducive to the 3 D stereo position that depth perception module obtains pupil or eyes.
When realizing active or passive-matrix, it is preferentially considered as being realized with the good conductive material of transparency,
Other than ITO electrode, it is also contemplated that using Graphene electrodes.When realizing TFT, it is saturating that excessively high resolution ratio can reduce light
Rate is crossed, suitable resolution ratio is extremely important, while to pay the utmost attention to use low temperature polycrystalline silicon (LTPS), rather than amorphous silicon (a-
Si).It is also contemplated that Organic Thin Film Transistors (OTFT) or oxide semiconductor TFT (such as based on IGZO material as ditch
The TFT of road material) realization.Total consideration is to improve light transmittance as far as possible under the premise of guaranteeing to reach the demand to shut out the light
And transparency, reduce light losing.
Many vehicles are provided with lane holding and collision detecting device now, or even have servomechanism, these are all
Need depth perception module.The present invention can make full use of existing module, realize blocking on demand for light at lower cost.No
But can use existing depth perception module, the function of main control module can also be based on existing GPU, ASIC, FPGA, CPU,
The equipment such as SOC only need to increase at this time light penetration control module intelligent light can be realized and block to realize.

100 and the first depth perception module 101, matrix control module 103 and optional second depth perception module 102 composition.
When being used for intelligent headlight, the first depth perception module 101 can detect vehicle before current vehicle and
Pedestrian, and the depth data that detection obtains is sent to main control module 100, main control module 100 is calculated by certain, and sending refers to
Matrix control module 103 is enabled, the light source 104 of current vehicle is blocked according to instruction in whole or in part in the rank of pixel
Light beam prevents the dazzle of the light source 104 of current vehicle from causing to perplex to the vehicle and pedestrian of front.
When realizing intelligent headlight, the pedestrian in depth perception module detection front and vehicle, obtained 3 D stereo
Depth data is sent to main control module, and main control module can pass through each picture of hood of the matrix majorization before big lamp source
Element actively blocks the light beam of pedestrian and vehicle in front of directive.The key component of hood is exactly the PDLC of matrix driving, micro- blinds
Window or electrochromic material etc..PDLC material is voltage driving, and micro- shutter unit is electrostatic drive, electrochromic material
It is that electric current drives.For the easy degree of realization, low pixel when the direct square that can be separately addressed of each pixel
Battle array drives to drive, or with passive-matrix, and high pixel must just use thin film transistor (TFT) (TFT) active-matrix.Sea

The pupil of driver or the position of eyes calculate main control module is sent to from this two-part 3 D stereo depth data, obtain screening
The correct position for the matrix that positive plate should act, to reduce influence of the dazzle to driver as far as possible.When blocking, portion is paid the utmost attention to
Divide and block, to remind driver and passenger to notice that vehicle is carried out in front.For example sunglasses are put at night, it, can be very big although very dangerous
Degree on reduce the influence of dazzle, and the transparency of sunglasses is differed from 5 ~ 45%.The present invention attempts to imitate the transparency of sunglasses,
Such as although certain pixels have blocked the dazzle of distance light, even if when least transparent, it should also allow part direct projection
Light penetrates, for example 45% direct line is allowed to penetrate.For electrochromic material, such design is very significant, because
The raising of minimum light penetration means lesser electric current and relatively thin ITO conductive layer.The reality of partial occlusion said before
Existing method can be the driving voltage for adjusting certain pixels, for example use lower voltage or smaller current；Or with four
Pixel is one group, and two pixels in group are fully transparent, and other two is blocked completely, to realize that part to a certain degree hides
Gear.
