[0021] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0022] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0023] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0024] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0025] At present, as the assisted driving technology of vehicles becomes more and more mature, the driver's own vision requirements are gradually reduced when driving vehicles with higher assisted driving technology compared to traditional vehicles without assisted driving technology. Especially in vehicles with relatively mature intelligent driving technology, the driver's own vision requirements are further reduced. This is a rare blessing for some people with poor eyesight (myopia, hyperopia, astigmatism). For example, in the process of intelligent driving, the driver's vision may only be used to look straight ahead or out the window.

[0026] Generally speaking, people with poor vision (nearsightedness, hyperopia, astigmatism) cannot do without myopia glasses, and wearing glasses for a long time will cause fatigue, dizziness and even headaches for the wearer due to the pressure on the nose bridge. In particular, the wearer needs to concentrate his eyesight and look forward during long-distance driving, and long-term sitting in the car will lead to poor blood circulation, making the driver and passengers more likely to feel fatigue, dizziness and headaches.

[0027] Based on this, this embodiment provides a method for adjusting the field of view of vehicle glass, which can improve the comfort of drivers and passengers with poor eyesight when driving a vehicle for a long time. The method for adjusting the field of view of vehicle glass can be specifically executed by a vehicle-mounted terminal. The method proposed in the embodiment of this application will be described in detail below using the vehicle-mounted terminal as an exemplary execution subject.

[0028] Embodiment 1

[0029] Figure 1 The schematic flow chart of S210-240 of a method for adjusting the field of view of vehicle glass provided in an embodiment of the present application is shown. Figure 1 As shown, the method includes steps S210 to S240, which are described in detail as follows:

[0030] Step S210: Acquire facial image information of the driver and passenger in the vehicle, where the facial image information includes the facial contour area and facial contour position of the driver and passenger.

[0031] For example, a camera is installed in the vehicle, and the camera can be used to obtain facial image information of the driver and passengers in the vehicle in a real-time monitoring manner, and then the facial image information is analyzed through the on-board terminal to obtain the facial contour area and facial contour position of the driver and passengers.

[0032] In addition, after the vehicle terminal analyzes the facial image information and obtains the facial contour area and facial contour area of ​​the driver and passenger, the facial contour area can be marked and stored, so that when the same driver and passenger enter the vehicle, information that is beneficial to the field of view adjustment method of the vehicle glass can be quickly obtained. For example, after recognizing that the same driver has entered the vehicle according to the stored information, it is only necessary to obtain the facial contour position of the driver and passenger.

[0033] Step S220: Determine the required field of vision area of ​​the driver and passenger in the vehicle glass based on the facial contour area of ​​the driver and passenger.

[0034] In the present embodiment, the vehicle glass is a windshield. Of course, in other embodiments, the vehicle glass, in addition to the windshield, can also be a vehicle window glass, a rear windshield, etc. installed on the vehicle for assisting driving.

[0035] For example, when the driver or passenger enters the vehicle, the on-board terminal can issue a prompt to remind the driver or passenger to focus directly in front of the vehicle's windshield. After the on-board terminal confirms that the driver or passenger is focusing directly in front of the vehicle's windshield, the driver or passenger's facial contour area is obtained The projection on the windshield can be used to obtain the driver or passenger's core field of vision in the windshield.

[0036] It should be understood that the core area of ​​vision is the central part of the required area of ​​vision, and the area of ​​the required area of ​​vision is generally larger than that of the core area of ​​vision. The area of ​​the core area of ​​vision can just meet the normal vision requirements of the driver and passengers (that is, the field of vision is almost the same as when wearing glasses).

[0037] In addition, considering that there may be more than just the main driver in the vehicle, there may be other drivers and passengers, and different drivers and passengers have different vision requirements. Therefore, in this embodiment, the area of ​​the required field of view is smaller than the area of ​​the entire vehicle windshield. Of course, in other embodiments, if there is only the main driver in the vehicle, the area of ​​the required field of view may also be equal to the area of ​​the entire vehicle windshield.

[0038] It should be understood that when the area of ​​the required field of view is smaller than the area of ​​the entire front windshield of the vehicle, it is convenient for the passenger with normal vision sitting on the front passenger seat to see the situation outside the vehicle. Compared with the entire front windshield of the vehicle being the required field of view area, on the one hand, it can save the energy consumption of the vehicle in adjusting the front windshield to the target optical mirror, and on the other hand, it can also reduce the interference of the subsequent adjustment of the required field of view area to the target optical mirror to other passengers while satisfying the field of view of the main driver.

[0039] Step S230: Adjust the optical data of the windshield in the required field of view to obtain a target optical mirror surface; in this embodiment, the target optical mirror surface is an optical mirror surface that matches the eye power of the driver and passenger. Of course, in other embodiments, the target optical mirror surface can also be an optical mirror surface that matches the light intensity required by the driver and passenger.

[0040] In an exemplary embodiment of the present application, Figure 2 A schematic flow chart of S231-233 of a method for adjusting the field of view of a front windshield provided in an embodiment of the present application is shown, combined with Figure 2 As shown, the specific method of adjusting the optical data of the front windshield in the required field of view to obtain the target optical mirror surface includes steps S231 to S233, which are described in detail as follows:

[0041] Step S231: Obtain vision information of the driver and passengers.

[0042] For example, the central control display screen in the vehicle can be used to perform an eye test on the driver and passenger in the vehicle to obtain the vision information of the driver and passenger, wherein the vision information at least includes the focus position of the driver and passenger.

[0043] Optionally, the driver and passengers in the vehicle are given an eye examination through the central control display screen in the vehicle to obtain the focal position of the driver and passengers' vision information, including: firstly facing the driver and passengers' face to the camera in the vehicle that collects facial image information, then determining the driver and passengers' eye position, and then sending infrared rays to the driver and passengers' eye position through an infrared device in the vehicle, and performing eye examination on the driver and passengers' eyes through a retina retinoscope.

[0044] Step S232: Determine the target refractive index of the windshield within the required visual field area based on the vision information.

[0045] For example, a method for determining a target refractive index of a windshield in a required field of view based on vision information includes: first determining a target focal position of a driver or passenger based on vision information, wherein the target focal position includes one or more of a focal position suitable for myopia, a focal position suitable for hyperopia, and a focal position suitable for astigmatism; and then determining a target refractive index of the windshield in the required field of view based on the target focal position of the driver or passenger.

[0046] Step S233: adjusting the refractive index of the windshield in the required field of view to a target refractive index to obtain a target optical mirror surface.

[0047] In this embodiment, the windshield is a temperature-sensitive glass, that is, the refractive index of the windshield can be changed by adjusting the temperature.

[0048] Alternatively, the front windshield may be formed of silicon hydride, wherein silicon hydride is a material having temperature-sensitive refractive index characteristics.

[0049] Alternatively, the windshield may be formed of certain polymers (eg, polyvinylpyrrolidone (PVP). PVP is a thermosensitive polymer whose refractive index changes with temperature. It is commonly used in optical modulation devices and sensors, such as temperature sensors and optical thermometers.

[0050] Optionally, the windshield can be formed of a polymer dielectric: a polymer dielectric has temperature-sensitive refractive index properties, such as modified polyethylene or polyvinyl chloride-based materials. They can be used to modulate optical signals or as part of an optical sensor. Polymer composites: By controlling the chemical composition and structure of polymer composites, the temperature dependence of their refractive index can be adjusted. These materials are commonly found in optical filters and optical modulation devices.

[0051] Optionally, the windshield may be fluoride glass: fluoride glass materials with specific compositions have different refractive indices at different temperatures, and are suitable for temperature compensation of optical elements.

[0052] Optionally, the windshield can be formed of a liquid crystal material, and the refractive index of the liquid crystal material can be adjusted by an electric field or temperature. For example, a layer of glass formed by adding a layer of liquid crystal material to the original windshield. Among them, normal nematic liquid crystal: In normal nematic liquid crystal, as the temperature changes, the order and arrangement of the molecules will change, thereby affecting the refractive index. Generally speaking, normal nematic liquid crystal has a lower refractive index at higher temperatures and a higher refractive index at lower temperatures. This is because at high temperatures, the molecules are more randomly arranged, resulting in a lower refractive index, while at low temperatures, the molecules are arranged in an orderly manner, resulting in a higher refractive index. Negative nematic liquid crystal: Negative nematic liquid crystals usually show the opposite trend when the temperature changes. In normal nematic liquid crystals, as the temperature increases, the order of the molecules increases, resulting in an increase in the refractive index; conversely, as the temperature decreases, the refractive index decreases.

[0053] For example, a method for adjusting the refractive index of a windshield within a field of view requirement area to a target refractive index to obtain a target optical mirror surface includes: determining a target temperature value of the windshield within the field of view requirement area based on the target refractive index; and adjusting the temperature value of the windshield within the field of view requirement area to the target temperature value to obtain a target optical mirror surface.

[0054] In an exemplary embodiment of the present application, the method of adjusting the refractive index of the windshield in the field of view requirement area to the target refractive index to obtain the target optical mirror surface also includes: after adjusting the temperature value of the windshield in the field of view requirement area to the target temperature value, generating a reminder message.

[0055] It should be understood that the target refractive index and the target temperature value are generally converted by a fixed formula. However, different requirements of the driver and passengers for the field of vision, as well as in some special working conditions, may cause the target refractive index obtained by converting the target temperature value to deviate from the refractive index required by the driver and passengers. Therefore, after adjusting the temperature value of the front windshield in the field of vision requirement area to the target temperature value, a reminder message needs to be generated to remind the driver and passengers to check.

[0056] For example, the reminder information may be pushed to the driver and passengers via voice and / or web pages.

[0057] Furthermore, the method of adjusting the refractive index of the windshield in the field of vision requirement area to the target refractive index to obtain the target optical mirror surface also includes: prompting the driver and passengers to check whether the refractive index of the windshield meets the target optical mirror surface based on the reminder information; if not, adjusting the refractive index of the windshield in the field of vision requirement area to obtain the target optical mirror surface; if so, no further adjustment is performed.

[0058] For example, the temperature value of the windshield may be increased or decreased manually to adjust the refractive index of the windshield within the required field of view area.

[0059] Step S240: Associating the facial contour position of the driver or occupant with the position of the target optical mirror surface, so that the position of the target optical mirror surface in the windshield changes accordingly as the facial contour position of the driver or occupant changes.

[0060] It should be understood that when the vehicle is driving, the driver and passengers may move their bodies by tilting their heads, etc. In this case, the target optical mirror needs to move synchronously with the facial contour position of the driver and passengers, so as to at least ensure that the field of view toward the front windshield will not be affected when the driver and passengers move their bodies.

[0061] In summary, when a driver or passenger with poor eyesight enters a vehicle and the facial image information of the driver or passenger in the vehicle is obtained, the driver or passenger's required field of view area in the windshield can be determined based on the driver or passenger's facial contour area in the facial image information, and the optical data of the windshield in the required field of view can be adjusted to obtain an optical mirror that at least matches the driver or passenger's eye degree, thereby allowing the driver or passenger to drive the vehicle (especially during intelligent driving) without wearing glasses. In addition, by associating the driver or passenger's facial contour position with the position of the target optical mirror, so that the position of the target optical mirror in the windshield changes accordingly with the change in the driver or passenger's facial contour position, the driver or passenger can drive the vehicle and move his or her body without wearing glasses, thereby improving the comfort of the driver or passenger with poor eyesight when driving the vehicle for a long time.

[0062] Embodiment 2

[0063] Since the vehicle may need to be driven by the driver and passengers to see the situation outside the vehicle window glass (such as the vehicle window glass on the door). Therefore, the second embodiment is substantially the same as the first embodiment, except that the vehicle glass of the second embodiment includes not only the front windshield in the first embodiment, but also other vehicle glass except the front windshield in the first embodiment. Among them, the material and working principle of the other vehicle glass except the front windshield in the first embodiment of the second embodiment can be the same as those of the front windshield in the first embodiment, that is, they can all be adjusted to the target optical mirror surface.

[0064] Next, when the vehicle glass of the second embodiment includes not only the front windshield in the first embodiment but also other vehicle glass except the front windshield in the first embodiment, the method for adjusting the field of view of the vehicle glass is specifically introduced:

[0065] In an exemplary embodiment of the present application, a method for adjusting the field of view of vehicle glass includes: if a field of view requirement area is located outside the front windshield, determining whether the vehicle window glass reaches a preset height.

[0066] For example, when the driver moves and the facial contour area moves away from the front windshield, it can be predicted that the driver may look out of the window glass. At this time, it is necessary to determine whether the window glass has reached a preset height, so as to prepare for the driver's facial contour area to face the window glass and for the target optical mirror to move to the window glass.

[0067] Optionally, the preset height of the vehicle window glass needs to satisfy the requirement that the target optical mirror surface can be located within the vehicle window glass.

[0068] It should be understood that, generally speaking, the window glass is closer to the driver and passenger than the front windshield, and in order to adapt to the change in the distance between the target optical mirror and the driver and passenger, the optical data in the target optical mirror and the required field of view area in the target optical mirror may also change synchronously. In other words, the optical data in the target optical mirror is not static, and may change accordingly as the position of the target optical mirror changes, ultimately to meet the purpose of at least matching the eye degree of the driver and passenger.

[0069] Furthermore, the method for adjusting the field of view of vehicle glass includes: if the preset height is not reached, controlling the vehicle window glass to rise to a preset height so that the target optical mirror surface can be located inside the vehicle window glass, thereby facilitating the driver and passengers to view the situation outside the vehicle window glass.

[0070] In summary, the method for adjusting the field of view of vehicle glass in the second embodiment improves the comfort of drivers and passengers with poor eyesight when driving the vehicle for a long time, and also increases the normal field of view of drivers and passengers with poor eyesight.

[0071] Embodiment 3

[0072] The third embodiment is substantially the same as the first embodiment, except that the vehicle glass of the third embodiment is located at a different position from the vehicle glass in the first embodiment, but the material and working principle of the front windshield are the same as those in the first embodiment, that is, both can be adjusted to the target optical mirror.

[0073] In an exemplary embodiment of the present application, the vehicle glass is an auxiliary glass installed in the vehicle cabin. For example, the auxiliary glass is installed on the ceiling in the vehicle cabin and is rotatably connected to the ceiling in the vehicle cabin. The target optical mirror is located on the auxiliary glass, and the auxiliary glass is controlled by the vehicle terminal so that the auxiliary glass and the target optical mirror can change synchronously with the facial contour position of the driver and the passenger.

[0074] It should be understood that when the vehicle glass is an auxiliary glass installed in the vehicle cabin, when the driver and occupants' heads turn at a large angle, the target optical mirror on the auxiliary glass can also provide the driver and occupants with a continuous picture.

[0075] Embodiment 4

[0076] The fourth embodiment is substantially the same as the first embodiment, except that the application scenario is different. Specifically, the driver and passenger in the fourth embodiment includes not only the main driver, but also other drivers and passengers except the main driver.

[0077] Next, the method for adjusting the field of view of the vehicle glass is specifically introduced when the driver and passenger in the fourth embodiment include not only the main driver but also other drivers and passengers other than the main driver:

[0078] In an exemplary embodiment of the present application, a method for adjusting the field of view of vehicle glass includes: when there are multiple drivers and passengers, obtaining position information of the multiple drivers and passengers.

[0079] For example, the position information of each driver and passenger can be obtained through the camera in the vehicle, for example, it can be obtained that multiple drivers and passengers are respectively located in the main driver's seat and the front passenger seat.

[0080] Furthermore, the method for adjusting the field of view of vehicle glass also includes: determining the target optical mirror priorities of multiple occupants based on the position information of the occupants.

[0081] Furthermore, the method for adjusting the field of view of vehicle glass also includes: determining the priority of the target optical mirror of the main driver as the highest, and when the target optical mirrors of the drivers and passengers overlap, determining the final target optical mirror according to the target optical mirror priority.

[0082] It should be understood that when the vehicle has multiple drivers and passengers, and all of the drivers and passengers are visually impaired, they can obtain their respective target optical mirrors in a one-to-one correspondence according to the method of Example 1. However, when the target optical mirror of the main driver overlaps with the target optical mirrors of other drivers and passengers, the target optical mirror of the main driver should be given the highest priority, and then the overlapping area should be adjusted to the target optical mirror of the main driver, that is, the target optical mirror of the main driver is determined as the final target optical mirror according to the target optical mirror priority.

[0083] In summary, the method for adjusting the field of view of vehicle glass in the fourth embodiment improves the comfort of drivers and passengers with poor eyesight when driving the vehicle for a long time, and is also applicable to the situation of multiple drivers and passengers.

[0084] Embodiment 5

[0085] The fifth embodiment is substantially the same as the first embodiment, except that the function of the target optical mirror is not limited to being an optical mirror that matches the eye power of the driver or passenger.

[0086] It can be seen from the first embodiment that the target optical mirror surface can be obtained by adjusting the refractive index of the vehicle glass, so that the target optical mirror surface can be matched with the eye degree of the driver and the passenger.

[0087] The light transmittance of glass refers to the percentage of the transparent light flux to the incident light flux, and the light transmittance refers to the performance of light passing through the glass medium layer, which is usually expressed by transmittance or transmittance. It is the ratio of the remaining light intensity after the light intensity passes through to the incident light intensity. The refractive index is a physical quantity that describes the degree of deflection of light at the junction of two different media. It is closely related to the propagation behavior of light in glass. The refractive index directly affects the propagation speed of light in glass. The higher the refractive index, the slower the propagation speed of light in the glass medium layer, and vice versa. Therefore, there is a certain connection between the refractive index and light transmittance (light transmittance or transmittance).

[0088] Therefore, while adjusting the target optical mirror surface to match the eye power of the driver and occupant, the target optical mirror surface can also be adjusted to match the light transmittance required by the driver and occupant.

[0089] In an exemplary embodiment of the present application, the method for adjusting optical data of vehicle glass in a required field of view area further includes:
