Description

System for controlling screen brightness based on binocular distance ranging algorithm

Technical Field

The invention relates to the technical field of controlling screen brightness, in particular to a system for controlling screen brightness based on a binocular distance ranging algorithm.

Background

With the rapid development of the internet, electronic devices gradually go deep into learning and living. The myopia rate of teenagers in China shows a rising trend, and particularly under the influence of an epidemic situation course, the degree of eye use and the myopia rate of the teenagers are greatly increased due to the fact that the teenagers face the screen for a long time. Therefore, how to reduce the visual impairment caused by using the electronic device has become a significant issue.

The existing electronic equipment can automatically adjust the brightness, the blue light is reduced by adjusting the color temperature of the screen, soft red light and soft yellow light are utilized to generate light, so that the screen can turn yellow and become dark when people see the screen, but the eyes can feel more strenuous when people want to see the screen clearly under the outdoor environment or the strong light environment irradiated by high-brightness light in the daytime, and the reading experience of a user is seriously reduced.

Therefore, it is desirable to provide a system for controlling screen brightness based on a binocular distance ranging algorithm.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, an embodiment of the present invention provides a system for controlling screen brightness based on a binocular distance ranging algorithm, including a data acquisition module, a processing operation module, a visual operation module, a control screen module and a system operation logic, where the data acquisition module is electrically connected to the processing operation module, the processing operation module is electrically connected to the visual operation module, the visual operation module is electrically connected to the control screen module, the data acquisition module is located inside a front camera of an electronic device, the processing operation module is internally provided with a binocular distance ranging algorithm system, the binocular distance ranging algorithm system is used to calculate a user eye distance, and the system operation logic is used to analyze whether the user eye distance is qualified; the visual operation module is used for displaying the current eye using distance and setting the safe eye using distance; the control screen module is located in the brightness setting unit in the electronic equipment and is used for controlling the screen brightness.

As shown in fig. 2, the basic principle of binocular distance measurement is that internal and external parameters of a camera (C) of an electronic device need to be acquired, then binocular (OD, OS) is subjected to stereo calibration through stereo calibration, and finally, the average distance between the binocular (OD, OS) and the camera is determined (S1), namely the eye using distance, and the binocular distance measurement algorithm system calculates the eye using distance according to the principle, so that the difference between the eye using distance and the standard distance is obtained.

As shown in fig. 3, initially, the user opens the application, at this time, the pop-up box "yes/no" opens the camera right, "the user clicks" no, "the screen continues to pop up" opens the camera right "to remind the user to open the program, the user clicks" yes, "the eye distance and the interval time of the user are set according to actual needs, after the setting is completed, the application runs in the background, the background cannot be closed, otherwise, the function is disabled, when the set interval time is reached, the system starts to calculate the eye distance of the user at this time, and compares the calculated eye distance with the set distance, if the calculated eye distance is greater than the set distance, the screen brightness is unchanged, if the calculated eye distance is less than the set distance, the screen brightness becomes dark, and after one end of the time, the operation is repeated, and the cycle is repeated.

The working process of the invention is as follows:

according to the scheme, an operator needs to open an application program firstly, the eye using distance and the interval time of a user are set according to actual needs, after the setting is completed, the application program runs in the background, when the set interval time is reached, the system starts to calculate the eye using distance of the user at the moment, the eye using distance is compared with the set distance, if the eye using distance is larger than the set distance, the screen brightness is unchanged, if the eye using distance is smaller than the set distance, the screen brightness is darkened, after one end of time, the operation is repeated, and the operation is repeated in a circulating manner.

The system can calculate the eye distance of the current user through the setting processing operation module, and can judge whether the current distance is smaller than the set safe eye distance or not in time, so that the screen brightness is controlled, the user is reminded to keep the eye distance, the user is helped to develop good eye habits in life and study, and the visual damage degree of the user in the process of using the electronic equipment is reduced.

The points to be finally explained are: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may be a mechanical connection or an electrical connection, or a communication between two elements, and may be a direct connection, and "upper," "lower," "left," and "right" are only used to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship may be changed;
