In the embodiment of the disclosure, a control method and a control system for a transparent area range of a vehicle window are provided, so that the intelligent degree of the transparent area range of the intelligent vehicle window price adjustment is improved at least to a certain extent, and personalized requirements of different drivers are met.
Fig. 2 shows a flowchart of a control method for a transparent area range of a vehicle window in an exemplary embodiment of the present disclosure, and an execution subject of the control method for the transparent area range of the vehicle window may be a device having a calculation processing function, such as a server or the like. The implementation of the above method is explained below in connection with a control system for the transparent area range of a vehicle window.
The vehicle window provided by the embodiment comprises a transparency adjusting device, such as a PDLC or a PSCT. The transparency adjustment device may be another device having a transparency range characteristic controlled according to an energization range.
Illustratively, PDLC is taken as an example of the transparency adjustment device: the glazing structure may consist of two layers of transparent glass with a gap, and a PDLC device filled in the gap. Illustratively, the vehicle window structure may also be composed of a layer of transparent glass and a PDLC device attached to the transparent glass. Further, the window transparent area range is controlled by controlling the energization range of the PDLC device included in the window structure.
Referring to fig. 2, a control method of a transparent region range of a vehicle window according to one embodiment of the present disclosure includes the steps of:
step S210, responding to the driving state of the vehicle, and acquiring position information of a face key point of a first driver relative to a camera device through the camera device; and the number of the first and second groups,
step S220, determining a first power-on region of the transparency adjustment device according to a relative positional relationship among the facial key points, the camera device, and the rearview mirror of the vehicle, so as to control a transparent region range of the vehicle window.
In the technical solution provided by the embodiment shown in fig. 2, on one hand, when the vehicle is in a driving state, the transparent area of the window is adjusted in real time through the relative position relationship between the driver and the rearview mirror. It is thus clear that compare in the fixed door window of transparent region scope among the correlation technique, the transparent region scope of door window that this technical scheme provided is dynamic adjustment, can improve the intelligent degree of door window.
On the other hand, since different drivers have different heights and body types, the positions of the facial key points of different drivers are different when the drivers are in the driving state. According to the technical scheme, the position information of the face key points of the driver is obtained in real time, and the transparent area range of the vehicle window is further adjusted in real time according to the relative position relation between the face key points and the rearview mirror, so that the adjustment of the transparent area range of the vehicle window is associated with the positions of the face key points of the driver, and the personalized requirement of the user on the adjustment of the transparent area range of the vehicle window is favorably met.
On the other hand, the vehicle window provided by the technical scheme comprises the transparency adjusting device, and the range of the transparent area of the vehicle window is controlled by controlling the power-on range of the transparency adjusting device, so that the control accuracy is improved.
The following detailed description of the various steps in the example shown in fig. 2:
in an exemplary embodiment, fig. 3 shows a schematic view of a vehicle window structure according to an embodiment of the present disclosure. Referring to the drawings, the window according to the present embodiment is a side window 31, 32 (hereinafter, referred to as "window") on both sides of the front windshield 30. The vehicle window 31 includes a transparent region 311 with an adjustable range and a translucent region 312. Illustratively, the window transparency region range is adjusted by controlling the energization range of the transparency adjustment device.
In an exemplary embodiment, in step S210: in response to the vehicle being in a driving state, positional information of facial keypoints of the first driver relative to the camera is acquired by the camera.
For example, the operating state of the engine of the vehicle may be obtained to determine whether the vehicle is in a driving state. If the engine is in the working state, the vehicle is considered to be in the driving state. For example, whether the vehicle is in a driving state may also be determined according to a speed measuring device disposed at the wheel.
For example, when the vehicle is determined to belong to the driving state, the camera device is triggered to take a picture. Specifically, referring to fig. 3, the above-described imaging device 34 is mounted on the column 33. Wherein, the column 33 is located on the axis between the front windshield 30 and the side window 31.
For example, in the driving state, since the driver directly observes the rearview mirror 35 through the eyes, the above-mentioned key points of the face are specifically the human eyes 36, and the position information of the human eyes is obtained in real time through the camera device. In addition, in the driving state, the positions of the imaging device 34 and the mirror 35 (the default is the unfolded/unfolded state) are fixed. Thus, after acquiring the position of the human eye 36, and in step S220: the first energization region of the transparency adjustment device is determined in accordance with the relative positional relationship among the human eye 36, the imaging device 34, and the rearview mirror 35 of the vehicle to control the transparent region range of the window.
In an exemplary embodiment, fig. 4 is a top view of fig. 3, and fig. 4 is a schematic diagram illustrating a geometrical relationship between a human eye, an image pickup device and a rearview mirror according to an embodiment of the disclosure. According to the human eye position obtained in real time, the method specifically comprises the following steps: the horizontal distance L between the imaging device and the human eye and the angle θ of the plane where the window is located to the position of the human eye with the imaging device as the center are calculated based on the following formula to obtain the width X of the window transparent region 311.
Wherein, L represents a horizontal distance between the camera device and the human eye, S identifies a horizontal distance between the camera device and the rearview mirror, θ represents an angle of the plane where the window is located, which is deviated to the position of the human eye with the camera device as the center, β represents an angle of the plane where the rearview mirror and the window are located, and m is a positive number and represents a compensation value.
It should be noted that, since the test distance has a certain error, in order to further ensure that the side window does not affect the sight of the driver, the width of the transparent area is increased by the compensation value m (e.g. 10mm, 20mm, 30mm, etc.), so as to ensure that the driver can observe the rearview mirror through the transparent area of the window, thereby ensuring driving safety.
In an exemplary embodiment, after determining the width of the window transparent region 311, the window transparent region range is controlled, in particular by controlling the energization region of the transparency adjustment device.
In an exemplary embodiment, fig. 5 illustrates a schematic structural diagram of a transparency adjustment device according to an embodiment of the present disclosure. Referring to fig. 5, the transparency adjustment device 50 is attached to the transparent glass of the window, having the same outer shape as the transparent glass. Since the glass is transparent, the transparency of the transparency adjustment device 50 can be controlled to control the range of the transparent region of the vehicle window. Illustratively, the transparency adjustment device 50 includes a plurality of dimming cells 51, and the range of the transparent region of the vehicle window is adjusted by controlling the power-on data of the plurality of dimming cells, so that the control accuracy can be improved.
Illustratively, a PDLC device is exemplified as the transparency adjustment device 50. The PDLC device is manufactured by mixing a high polymer prepolymer and a nematic liquid crystal according to a certain proportion, wherein the high polymer prepolymer and the nematic liquid crystal are easy to mix together due to the similar molecular structures, and then the mixture is coated or poured into a liquid crystal box and then is subjected to polymerization reaction. The above polymerization method adopts a photo-polymerization phase separation, specifically, after a polymer prepolymer undergoes a polymerization phase reaction, the polymer is separated from liquid crystal molecules, and the liquid crystal molecules are close to each other to form liquid crystal droplets which are dispersed in the polymer. Illustratively, fig. 6 and 7 show a structure and an operation principle schematic diagram of a PDLC device according to an embodiment of the present disclosure.
Referring to fig. 6, in the PDLC device, liquid crystal molecules are self-aligned in the droplets and left and right droplets are also unnecessary alignment when no electric field is applied. Since the liquid crystal molecules are highly optically and dielectrically anisotropic materials, their effective refractive index does not match the matrix refractive index. That is, the liquid crystal molecules and the high molecular weight polymer are scattered by each other, and thus a mist state is formed. The PDLC device in the atomizing area can enable the corresponding part of the window glass to be in a semitransparent state, so that the privacy of people in the automobile is protected.
Referring to fig. 7, when an electric field is applied to the PDLC device, the liquid crystal molecules will be aligned in parallel, so that the refractive index of the polymer is consistent with the ordinary refractive index of the liquid crystal, no scattering occurs between the polymer and the liquid crystal molecules, and the liquid crystal cell will be in a bright state.
Meanwhile, the transparency value of the PDLC device is positively correlated with the current applied voltage value. Specifically, when the applied voltage is zero, the haze is completely reduced, and the transparency is the lowest. The car window provided by the technical scheme comprises the PDLC device, and the range of the transparent area of the car window is controlled by controlling the power-on range of the PDLC device, so that the control accuracy is improved. The electrified voltage value can be controlled to meet the requirements of different transparencies of users.
In an exemplary embodiment, the same driver is in the same attitude most of the time during his driving. That is, for the same vehicle, the positions of the facial key points of different drivers are different according to the heights and body sizes of the drivers. It can be seen that the positions of the key points on the face of different drivers are different when the driver is in the driving state. Meanwhile, the positions of the facial key points of the same driver are not substantially changed. Further, the window transparent area range value in the normal driving state of the driver may be associated with the driver. When the driver drives the same vehicle again, the window transparent area range value is determined quickly and accurately according to the associated information.
For example, fig. 8 is a flowchart illustrating a method for controlling a transparent region range of a vehicle window according to another exemplary embodiment of the present disclosure. Referring to fig. 8, the embodiment provides a method including:
step S810, acquiring facial feature information of the first driver; step S820, determining a first identification corresponding to the facial feature information of the first driver based on a face recognition model; and step S830, associating the first identifier with the first power-on area, and storing the first identifier in a database.
In the embodiment shown in fig. 8, the range information corresponding to the window transparent area is acquired in the normal driving postures/states of a plurality of drivers. And associates each driver with the range information of its corresponding window transparent area. Thereby being beneficial to quickly adjusting the range of the transparent area of the vehicle window to the state suitable for the current driver.
In an exemplary embodiment, the above-described compensation value m may also be associated with and stored in correspondence to the driver. Therefore, when the same driver drives the vehicle again, after the target identifier corresponding to the driver is determined through the face recognition model, the compensation value m associated with the target identifier is directly obtained and used for adjusting the transparent area range of the vehicle window. So as to further improve the intelligent degree of the control of the car window.
In an exemplary embodiment, in addition to the manner of intelligently adjusting the window transparent region range according to the manner described above, a control device (e.g., a knob or the like) may be provided in the vehicle, and the driver may manually adjust the transparent region range value, thereby diversifying the adjustment manner.
In an exemplary embodiment, fig. 9 shows a flowchart of a control method of a transparent area range of a vehicle window in still another exemplary embodiment of the present disclosure. Referring to fig. 9, the method provided by this embodiment includes steps S910 to S990.
In step S910, it is determined whether the vehicle is in a driving state.
In an exemplary embodiment, the specific implementation of step S910 is the same as the specific implementation of step S210, and is not described herein again.
In an exemplary embodiment, in response to the vehicle not being in a driving state, which indicates that the driver does not need to observe the rear state of the vehicle through the rear view mirror, step S990 is performed: and controlling the power-on area of the transparency adjusting device to be zero in response to the vehicle being in a stop state, so that the transparent area range of the vehicle window is zero, and privacy is protected to the maximum extent.
For example, referring to fig. 10, when the vehicle is in a stopped state, the power-on area of the PDLC device is adjusted to be zero, and the transparency adjustment device of the vehicle window 101 is completely atomized, so that the side window of the vehicle is in a completely opaque state, and the privacy in the vehicle is ensured. For example, at this time, the driver does not observe the road condition through the rear view mirror 102 of the vehicle, so the rear view mirror 102 may be in a folded state (i.e., a non-operating state) according to the driver's demand.
In the exemplary embodiment, steps S920-S990 are performed in response to the vehicle being in a driving state.
In step S920, facial feature information of the second driver is acquired; and determining a second identifier corresponding to the facial feature information of the second driver based on the face recognition model in step S930. In step S940, it is determined whether the database includes the second identifier.
In an exemplary embodiment, in response to the second identifier being included in the database, it is described that the energization region information associated with the above-mentioned second driver is stored in the database. Step S950 is performed: and acquiring a second power-on area associated with the second identifier, and powering on the transparency adjusting device according to the second power-on area. Therefore, the step of calculating the electrifying area through the relative positions of the face key points of the second driver, the camera device and the rearview mirror is saved, and the second driver can be quickly adjusted to a proper transparent area range.
In an exemplary embodiment, in response to the second identifier not being included in the database, it is indicated that the energization region information associated with the above-mentioned second driver has not been stored in the database. Step S960-step S980 are performed.
In step S960, acquiring location information of a facial key point of the second driver through the camera; in step S970, determining a second energization region to the transparency adjustment device to control a transparent region range of the window according to a relative positional relationship among the facial key points, the image pickup device, and a rearview mirror of the vehicle; and, in step S980, associating the second identifier with the second power-on area and storing to the database.
So that the next time the second driver drives the vehicle, the energization region can be determined quickly for it, and the transparent region range can be further adjusted.
In an exemplary embodiment, fig. 11 illustrates a flowchart of a method for determining a face recognition model according to an embodiment of the present disclosure, which may be taken as a specific implementation manner of the step S820 and the step S930. Referring to fig. 11, the method provided by this embodiment includes step S1110 and step S1120.
In step S1110, a plurality of face images are obtained, and a training sample is determined according to the face images; and, in step S1120, training a neural network model according to the training sample, and using the trained neural network model as the face recognition model.
The face recognition model is determined based on the big data, so that the recognition accuracy is improved, and further, the windows in the corresponding transparent area ranges are provided for different drivers, and the individual requirements of the different drivers are met.
