Fig. 4 is another flowchart of an eye protection method applied to an eye protection device according to an embodiment of the present invention, where the method specifically includes the following steps:
401. acquiring human eye characteristic information detected by a human eye detection module;
the content shown instep 401 is similar to the content shown instep 201, and for avoiding repetition, details are not described here, and reference may be specifically made to the content shown instep 201.
It can be understood that different light and dark areas can be obtained through different tracking modes, the embodiment takes dark pupil tracking as an example, when an IR light source is turned on, when someone stands in front of a screen to watch the screen, an IR camera can shoot and collect images of a viewer, and the principle of image formation is that IR light enters human eyes through pupils, the pupil areas of the human eyes form dark pupil areas without light reflection, and other areas outside the pupils form bright pupil areas with light reflection, so that the pupils form light and dark contrast with other parts, collected data after image shooting enters an image processor through an optical sensor, and because the pupils have light and dark contrast with other parts, the image processor easily distinguishes the positions of the pupils to obtain the characteristic information of the human eyes.
402. Determining an iris region of the human eye using the dark pupil region and the bright pupil region;
further, the human eye feature information includes a dark pupil region and a bright pupil region, taking dark pupil tracking as an example, where the dark pupil region is a pupil region and the bright pupil region is a cornea region. The dark pupil region can then be determined to be the iris region.
403. Determining a line-of-sight relationship between a human eye and a screen included in the blue light display device according to the iris region;
in a possible implementation manner, step 403 may include steps 4031 to 4033, where steps 4031 to 4033 are specifically as follows:
4031. projecting the iris area to the screen, and determining the projection area of the iris area;
it can be understood that, because the human eye detection module is arranged on the screen, the detected human eye characteristic information is positioned in front of the screen, and therefore, the projection area corresponding to the iris area can be obtained by taking the screen as a projection surface.
4032. When the projection area meets a preset iris area threshold, determining that a sight line relationship between the human eyes and a screen included in the blue light display equipment is a first sight line relationship, wherein the first sight line relationship is that the human eyes normally see the screen;
4033. and when the projection area does not meet a preset iris area threshold value, determining that the sight line relationship between the human eyes and the screen included by the blue light display equipment is a second sight line relationship, wherein the second sight line relationship is that the human eyes do not orthographically look at the screen.
It should be noted that, the relationship between the eyes and the screen can be determined by comparing the projection area with the preset iris area threshold, and if the eyes are watching the screen, the iris of the eyes should be in the state of looking at the screen, so the projection area at this time approaches to the complete iris area, and if the eyes are not watching the screen, the iris of the eyes should be in the state of not looking at the screen, so the projection area at this time is far smaller than the complete iris area. And then whether the human eyes look at the screen can be judged through the projection area. The preset iris area threshold value is an iris area interval, the maximum value of the interval can be the complete iris area, the minimum value of the interval is the complete iris area of 1/2, the projection area meets the preset iris area threshold value, the projection area is in the iris area interval, and the sight line relationship between the human eyes and the screen included by the blue light display device can be determined to be the first sight line relationship of the front-view screen of the human eyes. Similarly, if the projection area is not in the iris area interval, the projection area does not meet the preset iris area threshold, and the sight line relationship is the second sight line relationship of the screen which is not orthographically viewed by human eyes.
404. Outputting a control signal corresponding to the sight line relation by utilizing the sight line relation;
it can be understood that different control signals are corresponding to different sight relations to control the blue light film winding and unwinding module, and then the control signals corresponding to the sight relations are output through the sight relations to control the blue light film winding and unwinding module.
405. And controlling the working state of the blue light film collecting and releasing module according to the control signal, wherein the working state comprises the process of collecting or unfolding the blue light film.
In one possible implementation, the control module may convert the optical signal into an electrical signal through a photosensor to control the motor. If the control signal includes a first control signal and a second control signal, 405 may further include steps 4051 and 4052:
4051. when the sight line relationship is the first sight line relationship, the working states of a rotating motor and a moving motor are controlled according to a first control signal, so that the blue light film is unfolded to cover the screen;
it is understood that the first line of sight relationship indicates that the human eye is on the formal screen, and the first control signal is used to protect the human eye, and thus the first control signal may cover the blue light film on the screen. Accordingly, the first control signal may control the moving motor and the rotating motor to operate such that the blue light film is covered on the screen, wherein the first control signal includes a first pulse signal of the movement of the motor for controlling the movement of the rotating motor and the moving motor, respectively. Referring to fig. 3 and 5(a) to 5(b), fig. 3 may show a screen state when no one views the screen, and fig. 5(a) shows that when there is a first line-of-sight relationship, the first control signal controls the moving motor to move from the left side of the screen to the right side of the screen, and controls the rotating motor to rotate and unfold the blue film so that the blue film is overlaid on the screen as shown in fig. 5(b) to filter the blue light.
It can be understood that, when the blue light film completely covers the screen, at this time, if the blue light film is in the first sight relationship, the motor does not need to be controlled to move, and the current situation is kept. The sensing signal of the infrared probe is detected.
4052. And when the sight line relationship is the second sight line relationship, controlling the working states of the rotating motor and the moving motor according to a second control signal so as to enable the blue light film to be folded to the first target side edge of the screen.
It can be understood that the second sight line relationship indicates that human eyes do not have a front-view screen, and at this time, eye protection is not needed, so that the second control signal is used for folding the blue light film to display a real screen color, and therefore, the second control signal can fold the blue light film to the side of the first target. Therefore, the first control signal can control the moving motor and the rotating motor to operate, so that the blue light film covered on the screen is retracted to the first target side of the screen. Wherein the second control signal comprises a second pulse signal of the movement of the electric machine for controlling the movement of the rotary motor and the movement motor, respectively. Referring to fig. 5(b), fig. 5(c) and fig. 3, fig. 5(b) may show a screen state when the blue light film is covered on the screen, and fig. 5(c) shows that when the second line of sight relationship exists, the second control signal controls the moving motor to move from the right side of the screen to the left side of the screen, and controls the rotating motor to rotate to retract the blue film, so that the blue film is retracted to the first target side of the screen as shown in fig. 3 to display the real image color of the screen.
It should be noted that, if the first pulse signal is in the forward direction, the second pulse signal is in the reverse direction, or if the first pulse signal is in the reverse direction, the second pulse signal is in the forward direction. I.e. the control of the motor movement by the pulse signal is reversed. Further, the pulse signal includes a stop signal, or the pulse signal is a continuous pulse signal, and when a trigger signal of the infrared probe, that is, a stop motion signal, is received, the pulse output is stopped, and the motor is controlled to stop rotating, which is not limited in this example.
It can be understood that when the blue light film is folded to the first target side of the screen, if the blue light film is in the second sight relation, the motor does not need to be controlled to move, the current situation can be kept, the position of the moving motor detected by the infrared probe can be obtained to determine whether the motor is controlled to move, if the infrared probe on the left side is triggered, the motor does not need to be started to operate, and if the infrared probe on the right side is triggered, the motor needs to be started to operate. Whether the pulse signal is output or not can be determined by detecting the induction signal of the infrared probe.
