Abstract
The invention discloses a same-frequency imaging system, which comprises an imaging brightness source, an imaging screen and other light sources, wherein the imaging brightness source and the imaging screen work at the same frequency, and the invention has the beneficial effects that: according to the human sensing organ, the image source and the imaging screen flash at the same frequency, so that the interference of external light is avoided; the light brightness sensor can control the image source under light control, and automation is realized.
Description
Technical Field
The invention belongs to the field of optics, and particularly relates to a same-frequency imaging system and a same-frequency imaging method.
Background
The HUD is used on an automobile as a new technology, important information such as speed, navigation and the like is projected in front of a driver, and the driver can see the driving information of the automobile without lowering head, so that the driving safety is facilitated.
Windshield type HUD has been installed to a lot of motorcycle types on the market at present, when using, when external sunshine is too high, the driver sees the image on the display screen and will be more shallow this moment, sees unclear, will be unfavorable for the driver to watch relevant information this moment, and then influences and drives, and then the driver still need look relevant information low head, can make like this and drive the distraction, the potential safety hazard appears easily. Particularly, the HUD head-up display system of the outdoor vehicle can hardly see the imaging effect due to the fact that sunlight directly irradiates the driver.
Disclosure of Invention
In order to solve the above problems, the present invention provides a common-frequency imaging system and an imaging method, and the specific technical scheme is as follows:
a same-frequency imaging system comprises an imaging brightness source, an imaging screen and other light sources, wherein the imaging brightness source and the imaging screen work at the same frequency; the imaging brightness source is a light source, the imaging screen is an electronic control change screen and can be switched between a reflecting screen state and a transmission glass state according to the condition that whether the imaging brightness source is electrified or not, and other light sources can be beneficial light (light which is emitted by light rays which are emitted to an article and then reflected) which needs to be perceived by human eyes or harmful light which needs to be shielded, such as direct solar light, night automobile far-off lights and the like.
In practical application, the brightness of the imaging brightness source is adjusted according to the brightness of other light sources to reduce the light fall.
The further improvement lies in that: the light emitting mode of the imaging brightness source is a screen light emitting mode or a projection mode.
The further improvement lies in that: the imaging screen is made of an electro-variable material.
An imaging method using the same-frequency imaging system specifically comprises the following steps:
the method comprises the following steps: adjusting the imaging brightness source and the imaging screen to work simultaneously at a fixed frequency;
step two: the imaging brightness source works, the imaging screen works in a reflection state, and other light sources are filtered;
step three: the imaging brightness source is closed, the imaging screen is opened, the imaging screen works in a transmission type glass state at the moment, and other light rays can transmit through the imaging screen to complete a working period;
step four: and repeating the second step and the third step to enable the frequency of the flicker effect to be invisible to human eyes.
The further improvement lies in that: the energy of light entering human eyes is further adjusted by adjusting the duty ratio of the imaging screen during working and closing.
When harmful light in other light sources is more, for example, the vehicle is driven under the state of big sun, the working time of the reflection state of the imaging screen is increased, so that the harmful light enters human eyes and is reduced, meanwhile, in order to increase the energy of the imaging brightness source entering the human eyes after passing through the imaging screen, the original brightness of the imaging brightness source needs to be increased, the contrast fall is reduced, at the moment, part of beneficial light still enters the human eyes, the human eyes self-adaptive darkening environment is realized, and the working principle is similar to that of a sunglass.
When the harmful light in other light sources is less, the working time of the reflection state of the imaging screen is reduced, and the light of the imaging brightness source can be obtained, for example, when driving at night.
By the condition of external light, a light sensor can be added into the system, so that the duty ratio and the brightness of the imaging brightness source and the duty ratio of the imaging screen can be automatically adjusted.
The invention has the beneficial effects that: according to the invention, according to the human sensing organ, the effect (beneficial or harmful) brought by the third party light is processed through the same-frequency flash of the image source and the imaging screen; the light brightness sensor can control the image source under light control, and automation is realized.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.
Examples
A same-frequency imaging system is disclosed, referring to FIG. 1, at this time, other light source lines are set as ambient light, including an imaging brightness source, an imaging screen and ambient light, the imaging brightness source and the imaging screen work at the same frequency, the light emitting mode of the imaging brightness source is a screen light emitting mode or a projection mode, and the imaging screen is made of an electrogenerated variable material.
An imaging method using the same-frequency imaging system specifically comprises the following steps:
the method comprises the following steps: adjusting the imaging brightness source and the imaging screen to work simultaneously at a fixed frequency;
step two: the imaging brightness source works, the imaging screen works in a state of a reflecting screen, and other light sources are filtered;
step three: the imaging brightness source is closed, the imaging screen is opened, the imaging screen works in a transmission type glass state at the moment, and other light rays can transmit through the imaging screen to complete a working period;
step four: and repeating the second step and the third step to enable the frequency of the flicker effect to be invisible to human eyes.
The energy of light entering human eyes is further adjusted by adjusting the duty ratio of the imaging screen during working and closing.
Traditional HUD mode can make the driver see not clearly under the highlight and be projected the image in the place ahead, HUD in the car is above-mentioned system of base member embedding, the windshield of formation of image screen in driver the place ahead, when external light is the highlight, increase formation of image screen reflective state operating time, make harmful light get into people's eye and reduce, the energy of getting into people's eye after passing through the formation of image screen in order to increase formation of image luminance source simultaneously, need increase the original luminance of formation of image luminance source, the contrast drop reduces, still there is some useful light to get into people's eye this moment, drive like in cloudy day, increase the comfort level that the driver drove.
