[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0034] Car glasses can not only provide users with richer entertainment and information interaction experience through virtual reality, intelligent adjustment and other technologies, but also improve driving safety and comfort. Among them, the intelligent adjustment of car glasses means that the lens of car glasses can adjust the light transmittance according to the changes in ambient light intensity to maintain the stability of the user's visual function, thereby improving driving safety.
[0035] However, when the ambient light intensity remains unchanged but the light intensity in the visual focus area of the user of the car glasses suddenly changes, the user of the car glasses will still experience blurred vision. Therefore, the intelligent adjustment based on the change of ambient light intensity still cannot effectively ensure the stability of the visual function of the user of the car glasses.
[0036] In view of this, the present application discloses a control method for car glasses, which can adaptively adjust the transmittance of the car glasses by paying attention to the changes in light intensity information in the effective focus area of the car glasses user, so that the effect of the car glasses in maintaining the stability of the user's visual function is more reliable.

[0038] The vehicle 12 can establish a communication connection with the vehicle-mounted glasses 11 in a wired or wireless manner. A control system can be provided in the vehicle-mounted glasses 11 or the vehicle 12, and the control system can be used to control the vehicle-mounted glasses 11, so that the vehicle-mounted glasses 11 can change the light transmittance of the vehicle-mounted glasses 11 according to the control of the control system.
[0039] Optionally, the control system may be a server or a server cluster composed of multiple servers. The lenses of the vehicle-mounted glasses 11 may include, for example, electrochromic lenses, liquid crystal lenses, and any other lenses that can adjust light transmittance according to a control signal of the control system.
[0040] Those skilled in the art should understand that the above-mentioned vehicle-mounted glasses 11 and vehicle 12 are only examples, and other existing or future vehicles or vehicle-mounted glasses, if applicable to the present application, should also be included in the scope of protection of the present application and are incorporated herein by reference.
[0041] Figure 2 This is a flow chart of a control method for vehicle-mounted glasses provided in an embodiment of the present application. The method can be executed by a control system installed in a vehicle, and the present application does not impose any limitation in this regard. Figure 2 The control method of the vehicle-mounted glasses provided in the embodiment of the present application may include the following steps:
[0042] Step S210, obtaining the sight line state information of the target object, where the target object is a user of the vehicle-mounted glasses, and the sight line state information is used to indicate the sight point of the target object.
[0043] Illustratively, the sight state information of the target object may be used to indicate, but not limited to, the position of the sight gaze point of the target object, whether the sight gaze point moves, the duration of the sight gaze point, etc. In some embodiments, the method of acquiring the sight state information of the target object may include, for example, acquiring the sight state information of the target object through a DMS (Driver Monitoring System) camera disposed in the vehicle.
[0044] Step S220, determining an effective focus area in the sight area of the target object according to the sight state information of the target object, wherein the effective focus area can be used to indicate an area in the sight area corresponding to the sight point of the target object.
[0045] The sight area may be, for example, an area corresponding to the range of the target object's sight when using car glasses. In some embodiments, the target object may be, for example, the driver of a vehicle, and the sight area of the target object may be, for example, an area corresponding to the range of the driver's sight, such as the road in front of the vehicle, the interior space of the vehicle, etc., and the present application does not impose any restrictions in this regard. As described above, the sight state information of the target object may be used to indicate the position of the target object's sight fixation point. Based on this, the area in the target object's sight area corresponding to the position of the sight fixation point may be determined as the effective area of interest based on the target object's sight state information.
[0046] Step S230, controlling the light transmittance of the vehicle-mounted glasses according to the sight state information and the light intensity information in the effective focus area.
[0047] Since light propagates differently in different areas of the target object's sight area, when the ambient light intensity remains unchanged but the target object's sight point changes, the light intensity felt by the target object may also change. For example, when the target object is in the driving position of a vehicle, the light intensity inside the vehicle may be lower than outside the vehicle due to the blocking of light by the vehicle body. When the target object's effective focus area is transferred from outside the vehicle to inside the vehicle, the light intensity inside the vehicle is lower than outside the vehicle, causing the target object to have blurred vision. In view of this, the embodiment of the present application can adjust the transmittance of the vehicle glasses according to the target object's sight state information and the light intensity information in the target object's effective focus area, so that the transmittance of the vehicle glasses is more in line with the actual usage needs of the target object.
[0048] Among them, as mentioned above, the effective focus area can be used to indicate the area in the sight area of the target object that corresponds to the position of the sight gaze point of the target object. The light intensity information in the effective focus area, that is, the light intensity at the position of the sight gaze point of the target object, can be used but not limited to as a basis for adjusting the transmittance of the vehicle-mounted glasses. In some embodiments, the method for obtaining the light intensity information in the effective focus area of the target object may include, for example: obtaining the light intensity information in the effective focus area of the target object through a light intensity detection device.
[0049] As mentioned above, different areas in the target object's sight area have different propagation modes. When the position of the target object's sight point changes, the target object may have a need to adjust the transmittance of the car glasses because the light intensity in different areas of the sight area may be different. When the position of the target object's sight point does not change but the ambient light intensity changes, the target object may also have a need to adjust the transmittance of the car glasses. In view of this, the target object's need to adjust the transmittance of the car glasses can be determined based on whether the target object's effective area of interest changes and whether the ambient light intensity changes. For example, when both the ambient light intensity and the target object's effective area of interest do not change, it is considered that the target object has no need to adjust the transmittance of the car glasses; when at least one of the ambient light intensity and the target object's effective area of interest changes, it is considered that the target object may have a need to adjust the transmittance of the car glasses.
[0050] It is considered that when the effective attention area of the target object remains unchanged, the adjustment requirement of the target object for the light transmittance of the vehicle-mounted glasses can be determined according to whether the ambient light intensity changes; when the effective attention area of the target object changes, the adjustment requirement of the target object for the light transmittance of the vehicle-mounted glasses can be determined according to the light intensity difference between the first effective attention area before the change of the effective attention area and the second effective attention area after the change of the effective attention area. In view of this, in order to improve the control efficiency of the vehicle-mounted glasses, different control methods for the light transmittance of the vehicle-mounted glasses in different scenarios can be set according to whether the effective attention area of the target object changes.
[0051] Among them, whether the effective attention area of the target object changes can be determined, for example, according to whether the line-of-sight fixation point of the target object moves. In some embodiments, determining whether the line-of-sight fixation point of the target object changes according to the line-of-sight state information may include: determining whether the line-of-sight fixation point of the target object moves according to the line-of-sight state information of the target object. If the line-of-sight fixation point of the target object does not move, it is considered that the effective attention area of the target object has not changed; if the line-of-sight fixation point of the target object moves, it is considered that the effective attention of the target object has changed.
[0052] In some embodiments, determining whether the line-of-sight fixation point of the target object moves according to the line-of-sight state information of the target object may include: determining the first position of the line-of-sight fixation point of the target object at the first moment and the second position of the line-of-sight fixation point of the target object at the second moment according to the line-of-sight state information of the target object. If the first position and the second position are inconsistent, it is determined that the line-of-sight fixation point of the target object has moved; if the first position and the second position are consistent, it is determined that the line-of-sight fixation point of the target object has not moved. Among them, the time interval between the first moment and the second moment is greater than the time threshold, and the value of the time threshold can be adjusted according to the actual application situation. The present application does not make any restrictions in this regard.
[0053] In some embodiments, when the effective attention area of the target object remains unchanged, controlling the light transmittance of the vehicle-mounted glasses according to the line-of-sight state information and the light intensity information in the effective attention area may include: determining whether the effective attention area of the target object changes according to the line-of-sight state information; if the effective attention area of the target object remains unchanged, controlling the light transmittance of the vehicle-mounted glasses according to the change of the light intensity information in the effective attention area. Among them, the light transmittance of the vehicle-mounted glasses is negatively correlated with the change of the light intensity information in the effective attention area. For example, when the light intensity in the effective attention area increases, the light transmittance of the vehicle-mounted glasses can be controlled to decrease; when the light intensity in the effective attention area decreases, the light transmittance of the vehicle-mounted glasses can be controlled to increase. Through the above method, the embodiments of the present application can improve the control efficiency of the vehicle-mounted glasses when the effective attention area of the target object remains unchanged, and further improve the use performance of the vehicle-mounted glasses.
[0054] Since the human eye has a certain tolerance for changes in light intensity, light intensity with a small change amplitude may not affect the visual function of the target object. In view of this, in order to further improve the performance of the vehicle-mounted glasses, the sensitivity of the vehicle-mounted glasses to light intensity changes can be reduced by setting a threshold for the light intensity change amplitude. In some embodiments, the transmittance of the vehicle-mounted glasses is controlled according to the change of the light intensity information in the effective focus area of the target object. For example, it may include: if the increase amplitude of the light intensity information in the effective focus area of the target object exceeds the first threshold, the transmittance of the vehicle-mounted glasses is controlled to decrease; if the decrease amplitude of the light intensity information in the effective focus area of the target object exceeds the second threshold, the transmittance of the vehicle-mounted glasses is controlled to increase. Among them, the first threshold and the second threshold may be the same or different, and the specific values of the first threshold and the second threshold may be adjusted according to the actual application scenario, and the present application does not impose any restrictions in this regard. Through the above method, the embodiment of the present application can fully consider the characteristics of the human eye when adjusting the transmittance of the car glasses, set a threshold value according to the tolerance of the human eye to changes in light intensity, so as to reduce the sensitivity of the car glasses to changes in light intensity, avoid frequent adjustment of the transmittance of the car glasses, and possibly cause interference to the normal visual function of the target object, thereby improving the performance of the car glasses.
[0055] In some embodiments, when the effective area of interest of the target object changes, the transmittance of the vehicle glasses is controlled according to the sight state information of the target object and the light intensity information in the effective area of interest. For example, it may include: determining whether the effective area of interest of the target object changes according to the sight state information of the target object; if the effective area of interest of the target object changes, the transmittance of the vehicle glasses is controlled according to the difference between the first light intensity information in the first effective area of interest and the second light intensity information in the second effective area of interest. Among them, the first effective area of interest may be, for example, the effective area of interest corresponding to the change before, and the second effective area of interest may be, for example, the effective area of interest corresponding to the change after. The change trend of the transmittance of the vehicle glasses is negatively correlated with the change trend of the difference. For example, when the change trend of the difference between the first light intensity information and the second light intensity information is decreasing, the transmittance of the vehicle glasses may be controlled to increase; when the change trend of the difference between the first light intensity information and the second light intensity information is increasing, the transmittance of the vehicle glasses may be controlled to decrease. Through the above method, the embodiment of the present application can improve the control efficiency of the vehicle glasses when the effective area of interest of the target object changes, thereby improving the use performance of the vehicle glasses.
[0056] As mentioned above, considering the tolerance of the human eye to changes in light intensity, the performance of the vehicle glasses can be improved by setting a threshold for the amplitude of light intensity changes. In view of this, in some embodiments, the transmittance of the vehicle glasses is controlled according to the difference between the first light intensity information in the first effective area of interest and the second light intensity information in the second effective area of interest. For example, it may include: if the first light intensity information in the first effective area of interest is less than the second light intensity information in the second effective area of interest, and the difference between the first light intensity information and the second light intensity information is greater than the third threshold, then the transmittance of the vehicle glasses is controlled to decrease; if the first light intensity information is greater than the second light intensity information, and the difference between the first light intensity information and the second light intensity information is greater than the fourth threshold, then the transmittance of the vehicle glasses is controlled to increase. Among them, the third threshold and the fourth threshold may be the same or different, and the specific values of the third threshold and the fourth threshold may be adjusted according to the actual application scenario, and the present application does not impose any restrictions in this regard.
[0057] Considering that in actual application scenarios, when the sight point of the target object moves a small distance, the light intensity in the sight area of the target object has a certain continuity, that is, the light intensity in the area with a close distance may remain unchanged or change slightly (the small change range can be, for example, the change range of the light intensity will not affect the visual function of the target object). In view of this, the sight area of the target object can be divided into different areas according to the change range of the light intensity. When the sight point of the target object moves in one of the different areas, it can be considered that the effective focus area of the target object has not changed, so as to reduce the difficulty of data collection, improve the detection efficiency of the light intensity information in the sight area of the target object, and thus improve the control efficiency of the vehicle glasses. In some embodiments, the sight area of the target object may include, for example: a first sight area within the sight range of the target object corresponding to the external environment of the vehicle, a second sight area within the sight range of the target object corresponding to the front seat area of the vehicle, and / or a third sight area within the sight range of the target object corresponding to the rear seat area of the vehicle.
[0058] As mentioned above, the light intensity in the same sight area of the target object may remain unchanged or the change in light intensity may not affect the visual function of the target object. At this time, the transmittance of the vehicle-mounted glasses can be controlled according to the change in light intensity information in the sight area corresponding to the sight point of the target object. In view of this, when the sight point of the target object moves in the same sight area, it can be considered that the effective focus area of the target object has not changed, and then the change in the transmittance of the vehicle-mounted glasses is controlled according to the light intensity information in the effective focus area to improve the control efficiency of the vehicle-mounted glasses.
[0059] In some embodiments, whether the effective focus area of the target object has changed can be determined, for example, based on the moving trajectory of the target object's line of sight fixation point. Determining whether the effective focus area of the target object has changed based on the line of sight status information can include, for example: determining the moving trajectory of the target object's line of sight fixation point based on the target object's line of sight status information; determining whether the effective focus area of the target object has changed based on the moving trajectory of the line of sight fixation point.
[0060] As described above, the sight state information of the target object can be used to indicate the position of the sight gaze point of the target object. In some embodiments, determining the moving trajectory of the sight gaze point of the target object according to the sight state information of the target object can include, for example: periodically acquiring multiple positions of the sight gaze point of the target object; and determining the moving trajectory of the sight gaze point of the target object according to the multiple positions of the sight gaze point.
[0061] In some other embodiments, whether the effective focus area of the target object has changed is determined based on the moving trajectory of the target object's gaze point. For example, it may include: if the moving trajectory falls entirely in the first sight area of the target object, or falls entirely in the second sight area, or falls entirely in the third sight area, then it is considered that the effective focus area of the target object has not changed; if the moving trajectory of the target object's gaze point does not fall entirely in the first sight area, or does not fall entirely in the second sight area, or does not fall entirely in the third sight area, then it is considered that the effective focus area of the target object has changed.
[0062] The control method of the vehicle-mounted glasses disclosed in the present application can lock the effective focus area that has a direct impact on the visual function of the target object according to the line of sight state information of the target object, and then control the transmittance of the vehicle-mounted glasses according to the line of sight state information and the light intensity information in the effective focus area, so that the transmittance of the vehicle-mounted glasses can be adjusted according to the actual usage needs of the target object, and can better adapt to the target object's needs for the transmittance of the vehicle-mounted glasses in various situations such as sudden changes in ambient light intensity, unchanged ambient light intensity but sudden changes in light intensity in the effective focus area, etc.
[0063] In some other possible implementations, the present application also provides a control device for vehicle-mounted glasses. Figure 3 is a schematic diagram of the structure of the control device of the vehicle-mounted glasses provided in the embodiment of the present application. Figure 3 The control device of the vehicle-mounted glasses provided in the embodiment of the present application includes:
