Description

Technical Field

[0001] The present invention relates to the technical field of anti-peeping screens, and in particular to an intelligent office method based on face recognition. Background Art

[0002] In an office environment, people move around relatively complicatedly, and computer screens are always in a relatively public area. The private content on the computer desktop cannot be effectively protected. It is generally not convenient for others to know some relatively confidential content. When working alone, users cannot accurately perceive whether there is screen peeking behind them, and when they perceive screen peeking, they usually directly block it or turn off the screen.

[0003] Chinese patent CN201610940061.5 provides a method, device and mobile terminal for processing iris information. The method obtains iris information and determines the iris angle value of the iris information. When it is determined that the iris angle value is not within the safe angle range, the light emission angle of the mobile terminal is adjusted.

[0004] This solution still has some inconveniences when adjusting the light emission angle of the mobile terminal. The overall adjustment of the light of the screen will limit the light of the operation screen and affect the user's operation. Once an anti-peeping incident occurs, the screen can only adopt a single, full-screen response method from beginning to end to issue warnings or anti-peeping processing, and it cannot take into account the user's current normal use of the operation screen.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the shortcomings of the prior art, the present invention provides an intelligent office method based on face recognition, which solves the technical problem that once an anti-peeping incident occurs, the screen can only adopt a single, full-screen response method from beginning to end to issue warnings or anti-peeping processing, and is completely unable to take into account the user's current normal use of the operation screen.

[0008] (II) Technical solution

[0009] In order to solve the technical problem that overall adjustment of the light of the screen will result in limited light on the operation screen and affect the user's operation, the present invention provides the following technical solutions:

[0010] A smart office method based on face recognition, comprising:

[0011] Step 1: Obtain user iris information and lock the user iris through the information acquisition module;

[0012] Step 2: When a peeping screen iris falls within the set recognition range, the information acquisition module captures the peeping screen iris position information and sends the peeping screen iris position information to the processing module;

[0013] Step 3: The processing module receives the position information of the iris of the peeping screen, processes the position information, and controls the screen to respond accordingly. The response includes the following methods:

[0014] When the screen is divided into a warning area and a privacy area, the operation screen of the privacy file displayed on the screen is moved to the current privacy area, and the warning area and the privacy area of ​​the current screen are controlled to respond differently;

[0015] When all areas of the screen are divided into warning areas, the screen is controlled to perform an anti-peeping screen response.

[0016] Preferably, the processing module includes a first processing module and a second processing module. After the location information is sent to the first processing module,

[0017] Or, the first processing module processes the position information and sends the processing information to the second processing module, and after the second processing module receives the processing information, the control screen responds accordingly;

[0018] Alternatively, the first processing module sends the position information to the second processing module, and the second processing module controls the screen to respond accordingly after processing the position information.

[0019] Preferably, in the step 2, the current position information of the peeping screen iris includes the position coordinates of the peeping screen iris; in the step 3, the processing module calculates the angle value ψ between each position area of ​​the screen and the position coordinates of the peeping screen iris; when the angle value ψ of the area is greater than the set value H, the area is a warning area; when the angle value ψ of the area is not greater than the set value H, the area is a privacy area.

[0020] Preferably, the anti-peep screen response includes switching a preset screen in the warning area;

[0021] The differentiated response includes performing light adjustment processing on the privacy area of ​​the screen and performing image adjustment on the warning area of ​​the screen.

[0022] Preferably, the light adjustment process includes:

[0023] The privacy area is divided into a number of strip areas P by a processing module, and the angle of the center position of each strip area relative to the iris information of the peeping screen is a weakening angle C. The light emitting end changes the light intensity and emission angle of the strip area corresponding to the weakening angle C according to the change of the angle value of the weakening angle C, so that the light intensity of the light emitting end changes with the change of the weakening angle C, and the emission angle of the light emitting end is equal to the angle value of the weakening angle C.

[0024] Preferably, the processing module calculates the screen area that the peeping screen iris can see at the current position based on the relationship between the lateral distance d between the peeping screen iris and the information acquisition module and the size of the screen, and the vertical distance b between the peeping screen iris and the information acquisition module. This screen area relative to the peeping screen iris is the warning area, and other areas in the screen are the privacy areas.

[0025] In the present invention, the lateral distance d and the vertical distance b between the peeping screen iris and the information acquisition module can be obtained by the information acquisition module, or the processing module can calculate the lateral distance d and the vertical distance b between the peeping screen iris and the information acquisition module according to the position coordinates of the peeping screen iris and the position coordinates of the information acquisition module.

[0026] Preferably, the information acquisition module detects and acquires a transverse angle value α between the user's iris and the peeping screen iris, and when the transverse angle value is less than a set value A, the information acquisition module detects and acquires a longitudinal angle value δ between the user's iris and the peeping screen iris;

[0027] If the longitudinal angle value α is greater than the set value B, the processing module controls the screen to adjust the longitudinal form; if the longitudinal angle value δ does not exceed the set value B, the processing module controls the screen to take emergency measures;

[0028] When the horizontal angle value α is not less than the set value A, the processing module controls the screen to be adjusted in a horizontal manner;

[0029] The horizontal form adjustment and the vertical form adjustment are respectively based on the width and height of the screen to divide the screen into a warning area and a privacy area.

[0030] Preferably, when the iris information acquired by the information acquisition module does not match the user's iris information, the processing module determines the iris as an iris intended to peek at the screen;

[0031] When the iris information matches the user's iris information, the processing module does not control the screen to respond.

[0032] Preferably, when the operation screen of the privacy file exists or partially exists in the warning area:

[0033] If the area of ​​the operation screen of the private file is smaller than the area of ​​the privacy region, the processing module controls the screen to automatically adjust the operation screen of the private file directly to the privacy region;

[0034] If the area of ​​the operation screen of the private file is not smaller than the area of ​​the privacy region, the processing module controls the screen to scale the operation screen of the private file proportionally to be smaller than the privacy region, and then automatically adjusts the operation screen of the private file to the privacy region;

[0035] If the operation screen of the private file does not exist in the warning area, the processing module does not process the operation screen of the private file in the current state.

[0036] Preferably, a smart office system based on face recognition includes:

[0037] An information acquisition module is used to identify the user's iris information, lock the user's iris, and capture the location information of the iris that is peeking at the screen;

[0038] An information storage module is used to store user iris information;

[0039] The processing module can receive the position information of the peeping screen iris, process the position information of the peeping screen iris, and control the screen to respond accordingly.

[0040] (III) Beneficial effects

[0041] Compared with the prior art, the present invention provides an intelligent office method based on face recognition, which has the following beneficial effects:

[0042] When a screen peeping incident occurs, the screen can respond in a targeted manner according to different anti-peeping situations. It can also take into account the anti-peeping screen without affecting the user's own use of private files, and can optimize the protection of the private file operation screen.

[0043] Since the present invention divides the screen into a warning area and a privacy area through a processing module, and moves the operation screen of the privacy file with the cooperation of the processing module, the degree of anti-peeping screen is optimized, the security of the operation screen of the privacy file is improved, and the problem that the existing overall adjustment of the screen affects the user's own operation is effectively solved. For example, when the user is learning or conceiving an optimized design of a full-screen image that needs to be kept confidential, when a peeping event occurs, the image can be moved to the privacy area. On the one hand, it plays a two-way warning role for the user and the peeper. On the other hand, because the image has undergone a transfer of the screen position (such as proportionally reduced to a limit in the privacy area), it also reduces the peeping clarity of the peeper without affecting the user's normal use of the image, thereby effectively achieving the anti-peeping screen effect.

[0044] Furthermore, the present invention selects different adjustment methods by calculating and judging the position of the peeping iris and the user's iris, thereby effectively avoiding the problem of anti-peeping measures becoming ineffective when the position of the peeping person is close to the user's position, and further improving the security of the private file operation screen.

[0045] Furthermore, the present invention divides the privacy area into a number of strip areas, and controls the light emitting end in each strip area through a processing module to change the light intensity and emission angle of the strip area corresponding to the weakening angle according to the change of the weakening angle value, so that the light intensity of the light emitting end decreases proportionally with the geometric decrease of the weakening angle, and the emission angle of the light emitting end corresponds to the angle value of the weakening angle, so that the picture light in the privacy area tends to be uniform, and the picture is ensured to ensure that the screen peeper cannot view the private file picture, and the rationality of screen adjustment is improved, thereby avoiding the problem that although the protection is achieved during the light adjustment, the line of sight is also blocked.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes an intelligent office method based on face recognition.

[0054] Example 1

[0055] See also Figure 1 , 2 6. An intelligent office method based on face recognition, comprising:

[0056] The information acquisition module collects the user's iris information and the information storage module stores the user's iris information collected by the information acquisition module. The user's iris is an authorized iris and can use the operation screen of the privacy file normally. The information acquisition module of the present invention preferably uses a camera of the prior art, and of course it can also be other electronic eyes, electronic probes, etc. of the prior art.

[0057] The preset screen is set by the processing module, and the preset screen is a file operation screen preset by the user.

[0058] The screen can be divided into horizontal and vertical forms.

[0059] This embodiment is introduced by taking the horizontal form adjustment method as an example, and the principle of the vertical form adjustment method refers to the horizontal form adjustment method.

[0060] The horizontal mode adjustment is to divide the screen into left and right areas, which are divided into a warning area and a privacy area; the vertical mode adjustment is to divide the screen into upper and lower areas, which are divided into a warning area and a privacy area.

[0061] The horizontal form adjustment and the vertical form adjustment are the differentiated processing based on the width and height of the screen respectively, and the horizontal form adjustment is taken as an example below;

[0062] When the user is operating on the private file screen, turn on the anti-snoop screen mode and perform the following operations:

[0063] The information acquisition module identifies the user's iris information and locks the position of the user's iris, and monitors other irises within the recognition range of the information acquisition module in real time. Other irises within the recognition range of the information acquisition module are peeping irises;

[0064] When the peeping iris is detected by the information acquisition module, the information acquisition module locks and captures the location information of the peeping iris;

[0065] The information acquisition module is used to acquire the position information of the peeping screen iris, and the processing module is used to calculate the angle value between each position area of ​​the screen and the position of the peeping screen iris;

[0066] like Figure 2 As shown, when the angle value ψ of the area is greater than the set value H, the area is a warning area; when the angle value ψ of the area does not exceed the set value H, the area is a privacy area; the set value H is preferably 5 to 20°.

[0067] Among them: the angle value ψ is: the angle value formed by the line connecting the projection of the peeping screen iris and its focus and the edge line of the projection of the screen closest to the focus of the peeping screen iris, when the peeping screen iris and the screen are vertically projected in the same plane along the screen height direction, and the edge line of the projection of the peeping screen iris on the screen closest to the focus of the peeping screen iris.

[0068] Then, according to the size of the operation screen of the private file and the position of the screen, the processing module moves the operation screen of the private file;

[0069] The processing module is used to adjust the image in the warning area and the light in the privacy area;

[0070] Furthermore, the picture adjustment process includes:

[0071] When the area of ​​the warning area is larger than half of the screen area, the processing module switches the preset screen of the warning area;

[0072] When the area of ​​the warning region does not exceed one half of the screen area, the warning region is frosted by the processing module.

[0073] Further, when the iris information acquired by the information acquisition module does not match the user's iris information, the processing module determines the iris as an iris intended to peek at the screen;

[0074] When the iris information matches the user's iris information, no anti-peeping operation is performed;

[0075] When the information acquisition module collects the intended iris peeping time for more than the set time value, it is determined to be iris peeping, and an anti-peeping operation is performed;

[0076] When the information acquisition module does not collect the intended iris peeping time for more than the set time value, it is determined to be an accidental iris peeping and no anti-peeping operation is performed.

[0077] Furthermore, if the area of ​​the operation screen of the privacy file is smaller than the area of ​​the privacy region, the processing module controls the screen to automatically adjust the operation screen of the privacy file directly to the privacy region;

[0078] If the area of ​​the operation screen of the private file is not smaller than the area of ​​the privacy region, the processing module controls the screen to scale the operation screen of the private file proportionally to be smaller than the privacy region, and then the processing module automatically adjusts the operation screen of the private file to the privacy region;

[0079] If the operation screen of the private file does not exist in the warning area, the processing module does not process the operation screen of the private file in the current state.

[0080] Furthermore, the present invention also discloses a light adjustment processing method, such as Figure 3 As shown, the light adjustment process includes:

[0081] The processing module divides the privacy area into n strip areas P, which are distributed from far to near the peeping screen iris, where the strip area farthest from the peeping screen iris is marked as P1, and the strip area closest to the peeping screen iris is marked as Pn. Figure 3 In the middle, 4 represents the strip area farthest from the peeking iris, and 5 represents the user's iris.

[0082] The angle of the center position of each strip area relative to the iris of the peeping screen is a weakening angle C. The light emitting end changes the light intensity and emission angle of the strip area corresponding to the weakening angle C according to the change of the angle value of the weakening angle C, so that the light intensity of the light emitting end changes with the change of the weakening angle C, and the emission angle of the light emitting end is equal to the angle value of the weakening angle C;

[0083] In a certain implementation, the light intensity is equal to the product of the coefficient K and the angle value of the weakening angle C, that is, the light intensity is proportional to the angle value of the weakening angle C, and the coefficient K is a preset parameter.

[0084] Furthermore, the present invention also provides a method for automatically performing online horizontal form adjustment or vertical form adjustment determination, so as to further improve the rationality of the division of the warning area and the privacy area, including:

[0085] The information acquisition module detects the horizontal angle value α between the user's iris and the peeping screen's iris. When the horizontal angle value α is less than the set value A, the information acquisition module detects the vertical angle value δ between the user's iris and the peeping screen's iris.

[0086] If the vertical angle value δ is greater than the set value B, the processing module controls the screen to adjust the vertical form; if the vertical angle value δ does not exceed the set value B, the processing module controls the screen to take emergency measures; wherein the emergency measures include switching of preset screens or turning off the screen;

[0087] When it is not possible to perform differentiated processing through vertical and horizontal format adjustment, the operation screen of the private file is switched to a preset file operation screen, thereby effectively avoiding leakage of the private file.

[0088] When the horizontal angle value α is not less than the set value A, the processing module controls the screen to be adjusted in a horizontal manner;

[0089] Among them: the horizontal angle value α is the value of the angle formed by the line connecting the projection of the focus of the peeping screen iris and the focus of the information acquisition module and the line connecting the projection of the focus of the user iris and the projection of the focus of the information acquisition module when the peeping screen iris, the information acquisition module, and the user iris are vertically projected in the same plane along the height direction of the screen; the vertical angle value δ is the value of the angle formed by the line connecting the projection of the focus of the peeping screen iris and the projection of the focus of the information acquisition module and the line connecting the projection of the focus of the user iris and the projection of the focus of the information acquisition module when the peeping screen iris, the information acquisition module, and the user iris are vertically projected in the same plane along the width direction of the screen.

[0090] The present invention divides the screen into a warning area and a privacy area through a processing module, and moves the operation screen of the privacy file under the cooperation of the processing module, thereby optimizing the degree of the anti-peeping screen, improving the security of the privacy file operation screen, and effectively solving the problem that the existing overall adjustment of the screen affects the user's own operation;

[0091] By calculating and judging the position of the peeping iris and the user's iris, different adjustment methods are selected to effectively avoid the problem of anti-peeping measures being ineffective when the peeping person's position is close to the user's position, further improving the security of the private file operation screen;

[0092] By dividing the privacy area into several strip areas, the processing module controls the light emitting end in each strip area to change the light intensity and emission angle of the strip area corresponding to the weakening angle according to the change of the weakening angle, so that the light intensity of the light emitting end decreases proportionally with the geometric decrease of the weakening angle, and the emission angle of the light emitting end corresponds to the angle value of the weakening angle, so that the picture light of the privacy area tends to be uniform, so that the screen can be adjusted rationally on the basis of ensuring that the screen peepers cannot view the private file screen, and avoid the problem that when adjusting the light, although the protection is achieved, it also obstructs the sight of oneself;

[0093] By adopting multiple ways of screen division and taking different anti-peeping measures on the divided screens, the screen can be applied to environments with more complicated personnel, meet the anti-peeping screen requirements in different situations, and avoid the problem of affecting user operation caused by the single adjustment under the existing anti-peeping screen technology.

[0094] Example 2

[0095] See also Figure 1 , 4 5. This embodiment provides another method for implementing a smart office method for face recognition by dividing a warning area and a privacy area, including the following steps:

[0096] The processing module calculates the relative position information between the user's iris and the peeping screen iris and the distance between the peeping screen iris and the information acquisition module, and the processing module divides the screen into a warning area and a privacy area according to the relative position information and the distance;

[0097] Further, the information acquisition module detects the horizontal distance L and the vertical distance of the peeping iris from the information acquisition module;

[0098] The information acquisition module calculates the screen area that the peeping iris can see at this position according to the relationship between the horizontal distance L and the size of the screen and the horizontal distance L and the vertical distance. The screen area is a warning area relative to the peeping iris, and the other areas are privacy areas;

[0099] The information acquisition module monitors and acquires the lateral distance d between the peeping screen iris and the information acquisition module;

[0100] In some implementations, such as Figure 4 As shown, 1 is a screen; 2 is a peeping iris; 3 is an information acquisition module; the screen is preferably a computer screen.

[0101] The horizontal distance d is: the screen and the peeping screen iris are mapped on the same plane. In this plane, the distance between the position where the focus of the peeping screen iris is projected on the plane and the focus of the information acquisition module on the plane along the screen width direction; the vertical distance b is the distance between the position where the focus of the peeping screen iris is projected on the plane and the focus of the information acquisition module on the plane along the vertical and screen width direction;

[0102] If the horizontal distance d is greater than L / 2, where L is the width of the screen, the vertical line of sight of the peeping iris falls outside the computer screen. The information acquisition module collects the vertical distance b and the horizontal distance d of the peeping iris distance information acquisition module, and takes the vertical distance b, the horizontal distance d, and the visual angle β of the human eye as inputs to the processing module. The width L2 of the warning area is calculated by the following formula, and outputted.

[0103] L2 = 0.5L - (db × tan0.5β);

[0104] The area formed by L2 on the screen is the warning area D2, and the other areas of the screen form the privacy area D1.

[0105] The line segment corresponding to L2 in the width direction of the screen is: the starting point of L2 falls on the edge of the screen close to the iris, and the end point of L2 extends horizontally to the other side of the screen and falls on the boundary between the warning area and the privacy area.

[0106] In some implementations, such as Figure 5 As shown, 1 is the screen; 2 is the peeping screen iris; 3 is the information acquisition module; if the horizontal distance d is not greater than L / 2, L is the width of the computer, then the vertical line of sight of the peeping screen iris falls within the computer screen, and the information acquisition module collects the vertical distance b and the horizontal distance d of the peeping screen iris from the information acquisition module, and takes the vertical distance b, the horizontal distance d, and the visual angle β of the human eye as inputs, which are input into the processing module, and are calculated by the following formula to output the width L2 of the warning area.

[0107] L2 = 0.5L - (db × tan0.5β);

[0108] The area formed by L2 on the screen is the warning area D2, and the rest of the screen forms the privacy area D1.

[0109] The viewing angle β of the human eye is a fixed value, and the viewing angle β is based on the viewing angle value under the privacy film. The privacy film is mainly used to reduce the viewing angle of the screen for the person who peeks at the screen.

[0110] In addition: Example 1 is mainly based on the case where the field of vision of the peeping screen iris can completely cover the screen, and the warning area and the privacy area are divided according to the angle value and the set value of each position area of ​​the screen and the peeping screen iris, wherein the set value can preferably be 5 to 20°; Example 2 is mainly based on the case where the screen is covered with an anti-peep film, and the anti-peep film weakens the range of the visible angle β of the human eye, so that the field of vision of the peeping screen iris cannot completely cover the screen, and the warning area and the privacy area are divided according to the visible angle and position information based on the anti-peep film.

[0112] like Figure 6 As shown, this embodiment discloses an intelligent office system based on face recognition, including:

[0113] An information acquisition module is used to identify the user's iris information, lock the user's iris, and capture the location information of the iris that is peeking at the screen;

[0115] The processing module can receive the position information of the peeping screen iris, process the position information of the peeping screen iris, and control the screen to respond accordingly.

[0116] Preferably, the processing module may adopt a computer processor.

[0117] Preferably, the processing module includes a first processing module and a second processing module, and the location information is sent to the first processing module.

[0118] Or, after processing the position information, the first processing module sends the processing information to the second processing module, and after receiving the processing information, the second processing module controls the screen to respond accordingly;

[0119] Alternatively, the first processing module sends the position information to the second processing module, and the second processing module controls the screen to respond accordingly after processing the position information.

[0120] Preferably, the second processing module adopts a computer processor.

[0121] Preferably, the anti-peeping screen response includes at least one of picture adjustment, light adjustment, screen off, and preset picture switching.

[0122] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
