FIG. 1 illustrates a flow 100 of some embodiments of a vehicle control method according to the present disclosure. The vehicle control method is applied to driving a vehicle and comprises the following steps:
Step 101, controlling an on-board camera of a driving vehicle to shoot a user image of a driving user, and determining whether the user displayed by the user image wears glasses or not.
In some embodiments, an execution subject of the vehicle control method (e.g., an in-vehicle controller mounted on a driving vehicle) may control an in-vehicle camera of the driving vehicle to capture a user image of a driving user, and determine whether a user displayed by the user image wears glasses. Here, the in-vehicle camera may be a camera built in the vehicle for driving the vehicle, for photographing the driver. For example, the in-vehicle camera may be a DMS (Driver Monitoring System) camera. In practice, the execution subject may recognize whether or not the eye region of the user displayed with the user image is provided with glasses through a neural network model (for example, a convolutional neural network model) for recognizing glasses or a DMS (Driver Monitoring System) camera.
And 102, in response to determining that the user displayed by the user image wears glasses, extracting an area image of the glasses displayed in the user image as a glasses area image.
In some embodiments, the executing body may extract, as the glasses area image, an area image of the glasses displayed in the user image in response to determining that the user displayed the user image wears the glasses. In practice, the execution subject may extract, as the glasses area image, the area image of the glasses displayed in the user image in various ways. For example, the region image of the glasses displayed in the above-described user image may be extracted as a glasses region image by an OpenCV-based partial image extraction technique or a neural network model for extracting glasses images trained in advance.
And step 103, adjusting the screen brightness of the vehicle-mounted screen and the instrument panel of the driving vehicle according to the eyeglass region image.
In some embodiments, the executing body may adjust screen brightness of an on-board screen and an instrument panel of the driving vehicle according to the glasses area image. In practice, first, the above-described execution subject may recognize the skin color value of the driving user included in the glasses area image as the first color value (i.e., the color value of the skin area covered by the glasses) through the DMS (Driver Monitoring System) camera. Next, the executing body may recognize the color value of the facial skin of the non-glasses area of the driving user as the second color value through the DMS (Driver Monitoring System) camera. The ratio of the first color value to the second color value may then be determined as the eyeglass transmittance. Then, a screen brightness corresponding to the above-mentioned glasses transmittance is selected as a target screen brightness from a preset screen brightness adjustment table based on the glasses transmittance. Finally, the screen brightness of the on-board screen and the dashboard of the driving vehicle may be adjusted to the target screen brightness. Here, the screen brightness adjustment table based on the transmittance of the glasses may refer to a table set in advance for comparing the transmittance of the glasses with the screen brightness. Here, the screen brightness adjustment table based on the glasses transmittance may be composed of the glasses transmittance section and the screen brightness corresponding to the glasses transmittance section. For example, the screen brightness adjustment table based on the transmittance of the glasses may be:
| Glass light transmittance interval | Screen brightness (cd/m) 2 ) |
| ＞＝0.9 | 2 |
| < 0.9 and > =0.8 | 3 |
| < 0.8 and > = 0.7 | 4 |
| … | … |
。
In practice, the screen brightness corresponding to the glasses transmittance section including the above-mentioned glasses transmittance may be selected as the target screen brightness from the screen brightness adjustment table based on the glasses transmittance.
In some optional implementations of some embodiments, the executing body may adjust the screen brightness of the on-board screen and dashboard of the driving vehicle according to the glasses area image by:
first, the type of glasses displayed by the glasses area image is identified, and the ambient brightness in the driving vehicle is identified. In practice, the execution subject may recognize the type of glasses displayed by the glasses area image and recognize the ambient brightness in the driving vehicle in various ways. Here, the type of glasses may refer to a category of glasses, and may include, but is not limited to: a sunglass type and a non-sunglass type. For example, the type of glasses displayed by the above-described glasses region image may be identified by a neural network model (e.g., a full convolutional network (Fully Convolutional Networks, FCN)) trained in advance for identifying the type of glasses. For example, the above-described ambient brightness in the driving vehicle may be recognized by a brightness detector or DMS (Driver Monitoring System) camera.
And a second step of identifying the transmittance and the abrasion degree of the glasses displayed in the glasses area image in response to the glasses type being a sunglasses type. Here, for the detection of the transmittance, see the implementation of generating the transmittance in the embodiment in step 103. In practice, for the recognition of the degree of wear of the glasses displayed in the above-described glasses area image, first, the wear area of the glasses displayed in the above-described glasses area image may be recognized by a neural network model (for example, a convolutional neural network model) trained in advance for recognizing the wear area of the glasses lenses in the image. Then, the ratio of the abrasion area to the total lens area of the glasses displayed in the glasses area image may be determined as the abrasion degree.
And thirdly, acquiring a transmittance-based brightness mapping table corresponding to the ambient brightness from the vehicle-mounted database of the driving vehicle. Here, the transmittance-based luminance map corresponding to the above-mentioned ambient luminance may refer to a luminance change table that changes with transmittance within a certain ambient luminance section set in advance. Here, the transmittance-based luminance map may be composed of a transmittance interval and the luminance corresponding to the transmittance interval. For example, when the ambient brightness is 5cd/m, the brightness map based on transmittance may be:
| Transmittance interval | Brightness (cd/m) 2 ) |
| ＞＝0.9 | 2.5 |
| < 0.9 and > =0.8 | 3 |
| < 0.8 and > = 0.7 | 3.5 |
| … | … |
。
Fourth, selecting a luminance corresponding to the transmittance from the transmittance-based luminance map as a target luminance. In practice, the luminance corresponding to the transmittance interval including the above-described transmittance may be selected as the target luminance from the transmittance-based luminance map.
And fifthly, adjusting the screen brightness of the vehicle-mounted screen and the dashboard to the target brightness in response to determining that the abrasion degree is smaller than a first preset abrasion degree. Here, the setting of the first preset wear degree is not limited. For example, the first preset wear level may be 0.9.
Optionally, in response to determining that the wear degree is greater than or equal to the first preset wear degree, a brightness increase value mapping table based on the wear degree of the glasses is obtained from the vehicle-mounted database.
In some embodiments, the executing body may obtain the brightness increase value mapping table based on the wear degree of the glasses from the on-vehicle database in response to determining that the wear degree is equal to or greater than the first preset wear degree. Here, the luminance increase value map table may refer to a table of luminance increase values that vary with the wear degree of the glasses. The brightness increase value map may be composed of a glasses wear degree section and brightness increase values corresponding to the glasses wear degree section. For example, the luminance increase value map table may be:
| Wear degree interval of glasses | Brightness increment value (cd/m) 2 ) |
| ＞＝0.9 | 0.1 |
| < 0.9 and > =0.8 | 0.2 |
| < 0.8 and > = 0.7 | 0.3 |
| … | … |
。
Alternatively, a luminance increase value corresponding to the degree of abrasion is selected from the luminance increase value map as the target luminance increase value.
In some embodiments, the executing entity may select a brightness increase value corresponding to the wear degree from the brightness increase value map as the target brightness increase value. In practice, the execution subject may select, from the luminance increase value map, a luminance increase value corresponding to the eyeglass wear section including the wear degree as the target luminance increase value.
Alternatively, the sum of the target luminance and the target luminance increase value is determined as a luminance adjustment value.
In some embodiments, the execution body may determine a sum of the target luminance and the target luminance increase value as a luminance adjustment value.
Optionally, screen brightness of the vehicle-mounted screen and the dashboard is adjusted to the brightness adjustment value.
In some embodiments, the execution body may adjust screen brightness of the in-vehicle screen and the dashboard to the brightness adjustment value.
The content in some alternative implementations is taken as an invention point of the present disclosure, thereby solving the second technical problem mentioned in the background art, namely that in a state that a user wears the sunglasses, the user cannot see the display and the dashboard clearly, and the safety of driving the vehicle is reduced. The reason why the safety of driving the vehicle is lowered is that: in a state that the user wears the sunglasses, the user cannot see the display and the instrument panel clearly, and safety of driving the vehicle is reduced. If the above factors are solved, the effect of improving the safety of driving the vehicle can be achieved. To achieve this effect, the present disclosure first recognizes the type of glasses displayed by the above-described glasses area image, and recognizes the ambient brightness in the above-described driving vehicle. Thus, data support is provided for adjusting screen brightness. Next, in response to the type of glasses being a sunglass type, the transmittance and the degree of wear of the glasses displayed in the glasses area image are recognized. Therefore, the brightness of the screen is convenient to adjust according to the transmittance and the abrasion degree of the glasses, so that a user can see the display and the instrument panel clearly. Then, a transmittance-based luminance map corresponding to the ambient luminance is obtained from the on-vehicle database of the driving vehicle. Thus, data support is provided for determining the brightness of the adjusted screen. Then, a luminance corresponding to the transmittance is selected as a target luminance from the transmittance-based luminance map. And finally, adjusting the screen brightness of the vehicle-mounted screen and the instrument panel to the target brightness in response to determining that the abrasion degree is smaller than a first preset abrasion degree. Therefore, in the state that the user wears the sunglasses, the screen brightness of the vehicle-mounted screen and the screen brightness of the instrument panel can be adjusted according to the transmittance of the sunglasses. Therefore, a driver with the sunglasses can see the display and the instrument panel clearly, and safety of driving the vehicle is improved.
In other optional implementations of some embodiments, the executing body may adjust the screen brightness of the on-board screen and dashboard of the driving vehicle according to the glasses area image by:
first, in response to the type of glasses being a non-sunglasses type, the wear degree of glasses displayed in the glasses area image is recognized as a target wear degree. Here, for a specific recognition of the target wear degree, reference may be made to the above-described implementation of recognizing the wear degree from among the transmittance and the wear degree of the glasses displayed in the above-described glasses area image. Here, the non-sunglass type may represent myopic glasses.
And a second step of determining whether the user displayed by the user image is a target user. Here, the target user may refer to an owner of the vehicle (owner user).
And thirdly, determining whether glasses information corresponding to the target user exists in the vehicle-mounted database or not in response to determining that the user displayed by the user image is the target user. Here, the glasses information may represent information that the target user wears glasses of a non-sunglasses type.
And step four, in response to determining that the glasses information corresponding to the target user exists in the vehicle-mounted database, acquiring the glasses information. Wherein, the glasses information comprises glasses degree and scattered light. In practice, the executing body may acquire the glasses information from the in-vehicle database in response to determining that the glasses information corresponding to the target user exists in the in-vehicle database.
And fifthly, responding to the degree of the glasses being larger than or equal to a preset degree and the degree of astigmatism being larger than or equal to a preset astigmatism, and acquiring a brightness mapping table based on the degree of the glasses and a brightness increment value mapping table based on the astigmatism corresponding to the ambient brightness from the vehicle-mounted database. Here, the brightness map table based on the degree of eyeglasses corresponding to the above-mentioned ambient brightness may be a brightness change table which changes with the degree of eyeglasses in a certain ambient brightness section set in advance. Here, the degree-based brightness map may be composed of a degree section and brightness of a corresponding degree section. Here, the luminance increase value map based on astigmatism may refer to a luminance increase value map that varies with astigmatism in a certain ambient luminance section set in advance. Here, the luminance increase value map based on the astigmatism may be composed of an astigmatism section and a luminance increase value corresponding to the astigmatism section. For example, the brightness map based on the degree of eyeglasses may be:
| spectacle power interval | Brightness (cd/m) 2 ) |
| ＜＝100° | 1 |
| > 100 ° and < = 200 ° | 1.5 |
| > 200 ° and < = 300 ° | 2 |
| … | … |
。
For example, the luminance increase value map based on the astigmatism may be:
| Scattered light interval | Brightness increment value (cd/m) 2 ) |
| ＜＝50° | 0.5 |
| > 50 ° and < = 100 ° | 1 |
| > 100 ° and < = 150 ° | 1.5 |
| … | … |
。

In practice, the brightness corresponding to the eyeglass power section including the eyeglass power may be selected from the eyeglass power-based brightness map as the first adjustment brightness.
Seventh, selecting a luminance increase value corresponding to the scattered light intensity from the luminance increase value map based on the scattered light intensity as a first luminance increase value.

In some embodiments, the executing body may adjust the screen brightness of the on-vehicle screen and the dashboard to the first adjusted brightness in response to the glasses power being equal to or greater than the preset power and the astigmatism power being less than the preset astigmatism power.
Optionally, in response to the eyeglass power being less than the preset power and the astigmatism power being greater than or equal to the preset astigmatism power, a brightness adjustment table based on ambient brightness is obtained from the vehicle-mounted database.
In some embodiments, the executing body may obtain the brightness adjustment table based on the ambient brightness from the vehicle-mounted database in response to the eyeglass power being less than the preset power and the astigmatism power being equal to or greater than the preset astigmatism power. Here, the brightness adjustment table based on the ambient brightness may refer to a brightness change table that is set in advance as the ambient brightness changes. The brightness adjustment table based on the ambient brightness may be composed of the ambient brightness section and the brightness of the corresponding ambient brightness section. For example, the brightness adjustment table based on the ambient brightness may be:
| ambient brightness interval (cd/m) 2 ) | Brightness (cd/m) 2 ) |
| ＜＝1 | 1.5 |
| > 1 and < = 2 | 2.5 |
| > 2 and < = 3 | 3.5 |
| … | … |
。
Alternatively, the brightness corresponding to the above-described ambient brightness is selected as the second adjustment brightness from the above-described ambient brightness-based brightness adjustment table.
In some embodiments, the executing body may select the brightness corresponding to the ambient brightness from the brightness adjustment table based on the ambient brightness as the second adjustment brightness.

Here, the specific implementation manner of adjusting the screen brightness of the on-board screen and the dashboard of the driving vehicle according to the target glasses information may be referred to the description in step 103, and will not be described herein.
The content in some alternative implementations is taken as an invention point of the present disclosure, thereby solving the technical problem three "the glasses degree and the astigmatism degree of the user are not considered, when the display brightness of the display and the dashboard is low or high, the display and the dashboard cannot be seen clearly by the user, and the safety of driving the vehicle is reduced. The reason why the safety of driving the vehicle is lowered is that: the degree of glasses and the degree of astigmatism of the user are not considered, and when the display brightness of the display and the instrument panel is low or high, the display and the instrument panel cannot be seen clearly by the user, so that the safety of driving the vehicle is reduced. If the above factors are solved, the effect of improving the safety of driving the vehicle can be achieved. To achieve this effect, the present disclosure first recognizes, as a target wear degree, a wear degree of glasses displayed in the glasses area image in response to the glasses type being a non-sunglasses type. Thus, data support is primarily provided for adjusting screen brightness. Next, it is determined whether the user displayed in the user image is a target user. Thus, it can be determined whether the user who drives the vehicle at the time is a temporary user. And then, in response to determining that the user displayed by the user image is the target user, determining whether glasses information corresponding to the target user exists in the vehicle-mounted database. Then, in response to determining that the glasses information corresponding to the target user exists in the vehicle-mounted database, the glasses information is acquired. Wherein, the glasses information comprises glasses degree and scattered light. Thus, it is convenient to adjust the screen brightness according to the user's glasses data. And then, in response to the degree of the glasses being greater than or equal to a preset degree and the degree of astigmatism being greater than or equal to a preset astigmatism, acquiring a brightness map based on the degree of the glasses and a brightness increment map based on the astigmatism corresponding to the ambient brightness from the vehicle-mounted database. Thereby facilitating the determination of the screen brightness that needs to be adjusted. Then, the luminance corresponding to the eyeglass power is selected as the first adjustment luminance from the eyeglass power-based luminance map. Then, a luminance increase value corresponding to the speckle pattern is selected from the luminance increase value map based on the speckle pattern as a first luminance increase value. Therefore, data support is provided for adjusting the screen brightness, and finally, the sum of the first adjusted brightness and the first brightness increasing value is determined to be a first brightness adjusting value, and the screen brightness of the vehicle-mounted screen and the screen brightness of the instrument panel are adjusted to the first brightness adjusting value. Thus, the display brightness of the display and the instrument panel can be adaptively adjusted according to the degree of eyeglasses and the degree of astigmatism of the user. Therefore, a user can see the display and the instrument panel clearly, and the safety of driving the vehicle is improved.
The above embodiments of the present disclosure have the following advantageous effects: according to the vehicle control method, in the state that the user wears the glasses, the display brightness of the display and the display brightness of the instrument panel can be adjusted adaptively, so that the user can see the display and the instrument panel clearly, and the safety of the automatic driving vehicle is improved. Specifically, the reason why the safety of the automatically driven vehicle is lowered is that: the display brightness of the display and the instrument panel cannot be adjusted adaptively according to the glasses worn by the user, so that the display brightness of the display and the instrument panel is brighter or darker, and the safety of driving the vehicle is reduced. Based on this, the vehicle control method of some embodiments of the present disclosure first controls the in-vehicle camera of the driving vehicle to capture a user image of the driving user, and determines whether or not the user displayed by the user image wears glasses, and then extracts, as a glasses area image, an area image of the glasses displayed in the user image in response to determining that the user displayed by the user image wears glasses. Thus, data support is provided for adjusting screen brightness. Finally, according to the glasses area image, the screen brightness of the vehicle-mounted screen and the instrument panel of the driving vehicle is adjusted. Thus, the screen brightness of the in-vehicle screen and the dashboard can be adjusted based on the glasses image. Therefore, the user can see the display and the instrument panel clearly, and the safety of the automatic driving vehicle is improved.
