Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
Example one
The invention provides an intelligent brightness adjusting method for an electronic outside rear-view mirror of an automobile, which is used for adjusting the brightness of an inside screen of the electronic outside rear-view mirror at two sides of a driver, and comprises the following steps as shown in figure 1:
step S1, acquiring a face image of the driver in real time;
step S2, determining the face orientation of the driver based on the face image, and adjusting the brightness of the in-vehicle screen according to the face orientation of the driver:
step S3a, responding to the judgment that the face of the driver faces to the front, and adjusting the brightness of the screens in the automobile at the two sides of the driver to a first preset brightness;
step S3b, responding to the judgment that the face of the driver faces to the left side, adjusting the brightness of the screen in the vehicle on the left side of the driver to a second preset brightness, wherein the second preset brightness is larger than the first preset brightness;
and step S3c, responding to the judgment that the face of the driver faces to the right side, adjusting the brightness of the in-vehicle screen on the right side of the driver to a third preset brightness, wherein the second preset brightness is larger than the first preset brightness.
Specifically, in the current smart vehicles, a Driver Monitoring System (DMS) is configured in a steering wheel area, and the DMS can collect and recognize information such as an expression and a face orientation of a Driver. In step S1 of the present invention, the intention of the driver to see the left electronic exterior mirror or the right electronic exterior mirror can be determined by obtaining the face orientation signal of the driver from the DMS, so that the brightness of the screen is increased when the driver needs to view the screen, and the brightness of the screen is decreased when the driver does not need to view the screen, thereby preventing the generated light from interfering with the driver' S sight.
For example, when the face of the driver faces forward, the brightness of the in-vehicle screens corresponding to the two electronic exterior mirrors can be adjusted to a darker degree, namely to a first preset brightness, and the range of the first preset brightness can adopt 100-200 lux brightness; when the face of the driver faces to the left, the brightness of the screen in the electronic exterior mirror on the left side can be adjusted to a higher degree, namely to a second preset brightness, and the second preset brightness can be 400-800 lux; when the face of the driver faces right, the brightness of the screen in the right electronic exterior rearview mirror vehicle can be adjusted to a third preset brightness, such as 400 lux-800 lux brightness; therefore, the screen in the automobile can keep darker brightness when a driver does not need to observe the screen in the electronic outside rearview mirror, the light in the automobile can be greatly reduced, and the driving safety is improved particularly when the driver drives at night; meanwhile, the service life of the screen in the vehicle is greatly prolonged; in addition, the energy consumption of the screen can be effectively reduced.
As an alternative embodiment, when the face image of the driver deviates to the left beyond a first preset angle, it is determined that the face of the driver is facing to the left; when the face image of the driver deviates to the right beyond a second preset angle, it is determined that the face of the driver is oriented to the right.
The face orientation detection is to comprehensively determine whether or not eyes are looking at the screen by an eyeball tracking technique in addition to the face angle detection.
Specifically, the first preset angle and the second preset angle may be the same or different. The first preset angle and the second preset angle are adjustable within a range of 30-45 degrees, in the embodiment, 30 degrees is taken as an example, when the face of the driver deviates to the left side by more than 30 degrees, it is judged that the driver wants to observe the left screen, and therefore the brightness of the left screen is adjusted from the first preset brightness to the second preset brightness; when the driver's face deviates more than 30 ° to the right, it is judged that the driver wants to view the screen on the right, and thus the screen brightness on the right is adjusted from the first preset brightness to the third preset brightness. It should be noted that the first preset angle and the second preset angle, including but not limited to 30 °, are only a preferred embodiment, and the problems of large judgment error and insensitive brightness adjustment caused by too large or too small values of the first preset angle and the second preset angle are avoided.
As an alternative embodiment, the first preset brightness is in a range of 100lux to 200 lux; the second and third preset luminances range from 400lux to 800 lux. It should be noted that the above-mentioned luminance ranges are only preferred embodiments of the present invention, and the range of the first preset luminance and the ranges of the second and third preset luminances may be determined according to actual application scenarios.
As an optional implementation, the brightness adjusting method further includes:
acquiring the ambient light intensity in real time, and comparing the ambient light intensity with the preset light intensity to judge whether to adjust the first preset brightness and/or the second preset brightness and the third preset brightness;
if the ambient light intensity is greater than the preset light intensity, increasing the first preset brightness and/or the second preset brightness and the third preset brightness;
and if the ambient light intensity is not greater than the preset light intensity, reducing the first preset brightness and/or the second preset brightness and the third preset brightness.
Specifically, through the technical scheme, different strategies can be made in the daytime and at night by setting the brightness of the screen in the electronic exterior mirror, for example, the value of the maximum brightness in the daytime can be larger, and the value of the minimum brightness at night can be smaller. For example, when the ambient light intensity is greater than the preset light intensity, it is determined that the current time is in the daytime, and a value of the first preset luminance may be increased, for example, the value of the first preset luminance ranges from 100lux to 200lux, and the value of the first preset luminance may be 200lux in the daytime and may be 100lux in the evening. Correspondingly, the values of the second and third preset luminances may be 400lux at night, and the values of the second and third preset luminances may be 800lux at daytime. The screen brightness is further adjusted according to the light intensity of the environment, the experience of a driver can be improved, and the driving safety is further improved.
