Description
Technical Field
The application relates to the technical field of intelligent terminals, in particular to an anti-dazzle method, an anti-dazzle device, electronic equipment and a storage medium.
Background
Along with the popularization of computers, notebooks and smart phones, screens of the smart devices become indispensable articles in the life of people, and a non-negligible problem, namely a large amount of glare generated by the screens, can occur due to the fact that people watch the smart screens for a long time. These screen glares can lead to refractive errors or visual dysfunction, and the possibility of inducing neurological and human biological clock disorders. Glare (Vision) is a visual condition that is caused to be visually uncomfortable and to reduce the visibility of objects due to an improper brightness distribution in the field of view, or due to extreme brightness contrast in space or time. A bright feeling is produced in the visual field that the human eyes cannot adapt to, and can cause aversion, discomfort or even loss of vision. An excessive brightness or an excessive brightness change in the front-rear direction occurs at a local place in the visual field. Glare is one of the important causes of visual fatigue.
According to the way of producing the glare, direct glare and indirect glare can be classified. The glare source of direct glare is located in the same direction and in the vicinity of the object to be observed, and refers to glare produced by light emitted from a light-emitting body having high brightness or glare not completely blocked in the lighting environment. The glare source of indirect glare is typically in a non-viewing direction, which is typically caused by light reflected from a highly smooth surface. Under indirect glare, when a screen such as a mobile phone and a computer is watched for a long time, the glare which continuously flickers on the screen can continuously stimulate eyes. As the eye continues to catch these rays and shadows, the eye will feel tired and damage the tear film on the surface of the globe, causing the eye to dry and deepen myopia. When there is intense light in a darker environment, the brightness of the two are in sharp contrast, and the intense light damages young retina tissues of children, resulting in visual dysfunction.

here, referring to fig. 3, fig. 3 is a schematic diagram of position measurement provided in the embodiment of the present application, as shown in fig. 3, after determining a target light source, a first vertical distance from the target light source to the camera may be obtained based on a principle of single/binocular ranging, because the measured distance is actually a vertical distance rather than a true distance, that is, the distance may be regarded as a first right angle edge in fig. 3, further, in the current image information, a distance (scaling in equal proportion, that is, f/d=h/H, f is a focal length of the camera, d is a distance from a lens to a target object, H is a length of an actual object, and d may be obtained based on a principle of single-or binocular ranging in the above embodiment, and further may be regarded as a second right angle edge approximately, and further, in the current image information, a point at which a point at a diagonal intersection point is located on a center line of the camera may be obtained, that is a triangle-shaped angle edge may be easily obtained based on the first angle edge, that is a right angle edge may be obtained by using the first angle edge, that is a distance of the camera, and the distance of the target light source is known relative to the first angle edge.
In some embodiments, obtaining face position information in the current image information according to the current image information includes:
determining a target face from the current image information;
acquiring a third vertical distance between the target face and the camera;
acquiring a fourth vertical distance between the target face and the central axis of the camera based on the internal parameters of the camera;
determining a second included angle between a straight line from the target face to the focal point of the camera and the central axis of the camera;
and determining the face position information of the target face in the current image information based on the current image information and the second included angle.
In some embodiments, determining the second included angle between the straight line from the target face to the focal point of the camera and the central axis of the camera may be implemented as follows:
constructing a second right triangle based on the third vertical distance and the fourth vertical distance, wherein a third right angle side of the second right triangle is a line passing through the third vertical distance along the central axis of the camera from the camera, a fourth right angle side of the second right triangle is a vertical line drawn from the target face to the central axis of the camera, and a second hypotenuse of the second right triangle is a connecting line from the target face to the camera;
determining a length of the second hypotenuse of the second right triangle based on the Pythagorean theorem;
acquiring a second included angle between the second hypotenuse and the third right angle side in the second right angle triangle based on a trigonometric function;
here, based on the same principle as the above embodiment, the positional information of the target face with respect to the camera, that is, the face positional information, can be found.
In addition, the second included angle may also be obtained by the following method:
a1: determining the inclination angle of the target face in the current image information;
a2: and taking the inclination angle as a second included angle between a straight line from the target face to the focus of the camera and the central axis of the camera.
Considering the habit of the user, the target face and the sight line are generally vertical, the inclination angle of the target face can be approximately regarded as an offset angle compared with a screen (central axis of a camera), the target face can be extracted from the current image information for the inclination angle (pose) of the target face, and calculated through an angle regression algorithm of a roll direction angle, such as PCN, or through Euler angle detection, or key points are extracted from the target face, and the inclination angle of the target face is estimated according to the key points.
In some embodiments, referring to fig. 2, fig. 2 is a schematic flow chart of steps S201 to S202 provided in the embodiments of the present application, where determining, according to the light source position information and the face position information, a reflection point on a screen of the terminal device when the light source reflects off the screen and irradiates the face may be implemented through steps S201 to S204, and will be described with reference to specific steps.
In step S201, a first relative positional relationship between a target light source and the target face with respect to the camera is determined according to the light source position information and the face position information.
In step S202, a second relative positional relationship between the target light source and the target face with respect to the terminal device is determined according to the relative positions of the camera and the terminal device.
In step S203, a normal to light reflection is determined based on the second relative positional relationship and the principle of reflection of light.
In step S204, a point at which the normal line intersects with the terminal device is taken as the reflection point.
Here, after the first relative positional relationship between the target light source and the target face with respect to the camera is obtained, since the relative positions of the camera and the terminal device are fixed, the second relative positional relationship between the target light source and the target face with respect to the terminal device (device screen) may be further obtained.
Then, according to the light reflection principle, the normal line of the target light source reflected to the target face through the terminal equipment screen can be determined, and the normal line is perpendicular to the terminal equipment screen, namely, the intersection of the normal line and the screen is the position of a reflection point (light spot).
In step S103, the reflection point is determined as a flare, and the screen brightness at the flare is adjusted.
In some embodiments, the adjusting the screen brightness at the spot includes:
and (3) increasing the brightness of the screen at the light spot, wherein the brightness of the screen at the light spot gradually decreases from the center of the light spot to the outer side. In the embodiments of the present application, the shape of the light spot is generally consistent with the shape of the target light source.
Here, the system adaptively displays matches around the spot, progressively brightens the patch area, and progressively weakens the brightness from the center of the spot to the outside, so that the impact of the spot on vision is weakened.
In some embodiments, the method further comprises:
and when the duration after the screen brightness at the light spot is adjusted exceeds the preset reminding time, displaying prompt information on the screen of the terminal equipment, wherein the prompt information is used for reminding the current user to rest.
Here, a reminding time can be preset, and because the anti-dazzle can only relieve the damage to vision, and the problem of glare can not be completely solved, when the preset reminding time is passed after the screen brightness is adjusted, a reminding message can be displayed on the screen of the terminal equipment (such as a mobile phone) to remind the current user to rest.
In summary, the embodiment of the application has the following beneficial effects:
