The device comprises a controller, a shading plate 1 and an image unit 3 which is connected with the shading plate 1 into a whole, wherein the controller is respectively connected with the image unit 3 and the shading plate 1, the controller is a general and well-known technology, so detailed illustration is not needed, a general embedded system can be adopted, the controller is usually a singlechip or an operation and control circuit with a data processing unit module, and usually a processor unit based on an RAM core, and corresponding peripheral elements and circuits are designed and configured according to needs.
In order to obtain image information in different directions, the above-mentioned image unit 3 is provided with two oppositely-facing image sensors, namely a front image sensor 31 and a rear image sensor 32, wherein the front image sensor 31 is used for collecting image information of a scene in front of eyes of a driver, especially information about strong light in the front scene; the rear image sensor 32 is used to collect driver face information to determine the position of the driver's face eyes for calculation of the position of the light valve 2.
The shading plate 1 is composed of a light valve 2 array composed of a plurality of rectangular area units, the light valve 2 is made of transparent liquid crystal or similar electric control and transmittance-variable materials, each rectangular area unit can change the working state of the light valve array under the control of different instructions of a controller, and the transmittance of different parts of the shading plate 1 is changed by a plurality of the arrays through different combinations and planes formed by change.
The controller is used for acquiring image information of the front side and the rear side acquired by the image unit 3 in real time, and through calculation, the front image sensor 31 searches and acquires the position of the strong light in the visual field image, namely, the position of the point of the strong light in the acquired image information is found, namely, the point can be a single point or multiple points, a light intensity threshold value can be set, the point higher than the set value is reserved as a characteristic point, and the point lower than the set value is abandoned.
As shown in fig. 1, while acquiring the front image information, the rear image sensor 32 searches the face information of the driver to obtain the positions of the eyes of the driver in the image information, when the light shielding plate 1 is located between the light emitting source 4 and the eyes of the driver, the relative position of the incident position of the strong light passing through the light shielding plate 1 to the eyes can be obtained by calculation, and the transmittance of the light valve 2 at the corresponding position on the light shielding plate 1 can be changed according to the obtained relative position coordinate value.
The size of the area of the light valve 2 can be automatically adjusted according to the size and intensity of the light source 4, as shown in fig. 2, when the light source 4 is weaker and farther, the light valve 2 is actually a small light valve area 21; when the light source 4 is relatively strong, the light valve 2 is actually a large light valve area 22, which is also generated due to the working state transition of the light valve 2 and is changed from the original transparent state to the opaque state, and the large light valve area 22 is also formed by arranging a plurality of small light valve areas 21, i.e. the effect of shading is achieved, and the effective line of sight is not blocked as much as possible, as the effect of the simulated light valve 203 in fig. 3.
As can be seen from fig. 1 and fig. 2 and the working process, the image unit 3 is disposed on the light shielding plate 1, and the viewing direction of the image unit 3 is perpendicular to the plane of the light valve array of the light shielding plate, so that when the light shielding plate is placed in front of the driver, i.e. the working plane of the light shielding plate 1, i.e. the plane where the light valve 2 is located, is perpendicular to the connection line between the driver and the light source 4, if the working plane of the light shielding plate 1 is not perpendicular to the connection line between the driver and the light source 4, the included angle between the working platform and the connection line can be detected and obtained, and at the same time, the included angle can be used for calculating the image position information.
Therefore, the image unit 3 on the light screen 1 has two image sensors with opposite directions, and is used for collecting the light information in front of the vehicle of the light screen 1 and the face information of the driver behind the light screen when the driver puts down the light screen 1.
Meanwhile, as shown in fig. 2 and 3, the light shielding plate 1 is composed of an array of light valves 2 formed by a plurality of rectangular area units, and the working state can be changed under the control of voltage so as to generate the change of transmittance.
In general, the array of light valves 2 of the light shielding plate 1 is made of liquid crystal material, and has different operating states under different voltages, thereby exhibiting different transparencies.
In addition, the light valve 2 array on the shading plate 1 can form identification for displaying road conditions and vehicle running information, which is equivalent to the effect of an automobile HUD, or displaying map geographic information.
In order to better realize the intelligent function, the intelligent sensor 5 arranged on the light screen 1 can be any one or the combination of an angle sensor, a speed sensor, a brightness sensor and the like, for example, the angle sensor can obtain the working angle of the light screen 1 in real time, and after the working angle is compared with the angle of a running vehicle, the relative position of the light valve 2 can be corrected and optimized; the speed sensor can obtain the running speed of the vehicle and provides reference data for the control device to calculate a prediction algorithm of the light source 4 at the projection position of the light shielding plate 1; the brightness sensor can obtain the brightness of the ambient light in real time, and provides reference data for adjusting the transparency of the light valve 2 on the light shielding plate 1.
Meanwhile, according to the angle sensor on the shading plate 1, the relative angle of the shading plate 1 can be obtained in real time, and a relative correction value is provided for the relative coordinate of the highlight position based on the angle information.
In addition, besides the device of the invention, the invention also relates to an intelligent vehicle-mounted shading method, which comprises the following steps:
1) two-way image sensors are arranged in front of a driver, one is a forward image sensor 31, and the other is a backward image sensor 32;
2) the forward image sensor 31 collects scene information in front of the eyes of the driver in real time, and obtains relative strong light position information in the scene image information according to the image information; the backward image sensor 32 collects the image information of the eyes of the driver in real time, and obtains the position information of the image information of the eyes of the driver according to the image information;
3) obtaining the relative coordinate value of the incident position of the strong light which penetrates through the shading plate 1 and is emitted to the eyes of the driver on the shading plate 1 through space calculation;
4) and changing the working state and transmittance of the corresponding light valve 2 or the simulated light valve region 203 at the relative position in real time according to the obtained coordinate value of the relative position.
The image information in the step 2) is obtained by: the forward image sensor 31 collects scene information in front of eyes of a driver in real time to obtain relative strong light position information in the scene image information, and the relative strong light position information is obtained according to projection information of strong light in the scene information, so that an X1Y1 coordinate point in a reference coordinate system is obtained; the real-time acquisition of the image information of the eyes of the driver based on the backward image sensor 32 to obtain the position information of the eyes of the driver is obtained based on the plane projection information of the eye image information, and an X2Y2 coordinate point in the reference coordinate system is also obtained.
The two reference coordinate systems are the same reference coordinate system, namely the X1Y1 point and the X2Y2 point are overlapped in the same coordinate system,
in addition, the calculation of the relative position in the step 3) is performed by: that is, the relative coordinate X1Y1 of the highlight position in the scene information and the relative coordinate X2Y2 of the eye image position may be superimposed in the reference coordinate system based on the light shielding plate 1, two points X1Y1 and X2Y2 may be connected in this coordinate system, and an X0Y0 coordinate is generated on a connection line between the two points according to a proportional relation point, and also located on a connection line between the highlight position coordinate and the eye position coordinate, this point coordinate is a relative position coordinate point of the light valve 2 that can change the operating state, that is, a coordinate point of the light valve 2, which is a simulated light valve area 203 in fig. 3, which is an effective and reasonable extension of the range of the light valve 2 to obtain a better shielding effect.
The proportional relation point on the connecting line between the two points is an empirical value generated according to tests and statistics, can be inserted or matched according to a list, and can also be calculated and optimized according to an intelligent image prediction algorithm.
Because the image information is collected and analyzed in real time, the position of the light valve 2 is changed in real time and is changed according to the position of the strong light, and the intelligent sensor 5 is provided for correcting data, especially the angle and speed sensor, so that the relative position coordinates of the light valve 2 can be calculated and corrected by using some optimization and prediction algorithms.
Thus, the light is opaque or low in transparency in the area of the light valve 2 or the analog light valve 203, while the other areas maintain high transparency or light transmittance, so that the driver is not only shielded from the strong light, but also has a large visual field. The problem of interference to a driver when the driver drives against strong light is solved, and meanwhile, the largest visible area is guaranteed.
