Unless otherwise defined, all terms (including technical and scientific terms) are used herein in the general sense they have in the field to which the example pertains.

[0034] It should be noted that the order of the steps in this paper can be flexibly configured, and the use of numbers to mark the steps is only for the convenience of description and has no restrictive effect.

[0035] Next, refer to Figures 1 to 3 The various aspects of the present invention are described in detail.

[0036] Figure 1 A partial schematic diagram of a vehicle 100 according to some embodiments of the present invention is shown. For example... Figure 1 As shown, vehicle user 200 (in this case, the vehicle driver) is inside the vehicle. In the text, vehicle 100 can be a mobile means of transport, such as a car, bus, truck, van, train, ship, motorcycle, tricycle, two-wheeler, or other mobile means of transport. It should be understood that a vehicle user can be any person inside the vehicle, including both passengers and the driver.

[0037] A camera 300 is schematically shown on the exterior of a vehicle. This camera can capture images of vehicle occupants inside the vehicle, for example, for facial recognition. These cameras can include those for commercial and industrial use, traffic purposes, environmental purposes, sanitation purposes, and infrastructure purposes. Most of these cameras are officially authorized and authorized to perform facial recognition for urban management. However, cameras on the road may also be used for covert filming to sell facial recognition data, leading to the leakage of personal information and privacy. Therefore, this invention proposes an in-vehicle anti-facial recognition system that effectively reduces the risk of vehicle occupants' facial data being recognized by cameras in the external environment, thereby reducing the risk of leakage of personal information and privacy.

[0038] Combination Figure 1 and Figure 2An anti-face recognition system 50 according to some embodiments of the present invention is described. The anti-face recognition system 50 may include a first projection device 10, which may be configured as an electromagnetic wave radiator and constructed to project interfering electromagnetic waves 101 toward a face, the interfering electromagnetic waves interfering with the recognition of the face. The interfering electromagnetic waves 101 may be projected onto an area in front of the face. The interfering electromagnetic waves 101 may be configured to introduce noise, particularly random noise, onto the face. In some cases, these interfering electromagnetic waves 101 may constitute image noise in the face recognition image. In this case, these interfering electromagnetic waves may be, for example, visible light noise. The first projection device 10 may project random visible light noise points toward the face. These visible light noise points are not easily perceptible from a human perspective, but are interfering with face recognition. This can effectively change the pixel values ​​of a certain number of pixels in the face image, thereby reducing the face recognition success rate. In some embodiments, these interfering electromagnetic waves may be, for example, strong light, infrared light, etc. Increasing the exposure by using strong light or infrared light can also reduce the face recognition success rate. In some embodiments, given the diversity of facial recognition algorithms, the interfering electromagnetic waves can distort the structure or contour of a face's three-dimensional image, thereby reducing the success rate of facial recognition. It should be understood that the generation of the interfering electromagnetic waves (e.g., their imaging and the applied or related algorithms) can be upgraded via the in-vehicle network to counter upgraded facial recognition algorithms or multiple different facial recognition algorithms. In some cases, algorithm switching can be performed for different types of cameras, such as high-definition cameras or cameras with special functions, for example, based on location information.

[0039] To facilitate the projection of interfering electromagnetic waves onto the area in front of the face, the first projection device 10 can be installed inside the vehicle in front of the face, allowing the interfering electromagnetic waves to directly penetrate the area in front of the face. For example... Figure 1 As shown, the first projection device 10 can be mounted on the steering wheel. In other embodiments, the first projection device 10 can also be mounted on the dashboard or the roof. It is also possible that interfering electromagnetic waves can indirectly enter the face area, for example, by reflecting onto the face area. It is also possible that multiple first projection devices are mounted at different locations within the vehicle, and these first projection devices can project onto the face respectively targeting different face areas and / or different recognition algorithms and / or different interference methods. Therefore, the placement of the first projection devices inside the vehicle can be diverse and flexible, and is not limited to the current embodiment.

[0040] Nevertheless, it is unavoidable that these interfering electromagnetic waves will enter the eyes, thus affecting the user experience. When the amount entering the eyes exceeds a certain level, users may experience glare, disorientation, or even eye damage. Especially for drivers, excessive interference from electromagnetic waves can impair driving safety and create traffic safety hazards.

[0041] To at least partially reduce the amount of interfering electromagnetic waves entering the eye, the anti-face recognition system 50 may include an eye-tracking device 12, which may be configured to track eye movements or detect the direction of eye gaze. Furthermore, the anti-face recognition system may include a control device 14, which may be communicatively connected to the eye-tracking device 12 and obtain the direction of eye gaze from the eye-tracking device. The control device 14 may manipulate the projection of the first projection device based on the obtained eye gaze direction, for example, adjusting the projection of the interfering electromagnetic waves toward the face.

[0042] Additionally or alternatively, the first projection device 10 may be configured to project a rotatable and / or movable interfering electromagnetic wave 101 toward the face. To this end, the control device 14 may adjust the projection direction of the interfering electromagnetic wave toward the face based on the acquired eye gaze direction, so as to at least partially avoid projection onto the eyeball. That is, the control device 14 may output adjustment commands to cause the interfering electromagnetic wave to rotate and / or move, so that the central axis of the electromagnetic wave is further away from the eyeball region, thereby reducing the amount of electromagnetic wave directly falling into the eyeball.

[0043] Additionally or alternatively, the first projection device 10 is configured to project a variable-intensity interfering electromagnetic wave 101 toward the face, and the control device 14 at least partially reduces the projection intensity of the interfering electromagnetic wave onto the eye region based on the acquired eye gaze direction. That is, the control device 14 can output adjustment commands to cause the interfering electromagnetic wave to at least locally reduce its radiation intensity, thereby reducing the intensity of the electromagnetic wave directly falling into the eye.

[0044] Alternatively or additionally, the eye-tracking device 12 can be configured as an in-vehicle camera. Preferably, the in-vehicle camera can also be configured to detect facial fatigue. Preferably, when the control device 14 detects facial fatigue, the control device 14 is configured to output a warning indication, thereby additionally providing the anti-facial recognition system 50 with the function of improving driving safety.

[0045] Additionally or alternatively, the anti-face recognition system 50 may advantageously include a second projection device 20 configured to generate a masking projection surface 102 for at least partially masking the face for recognition purposes. Figure 1 As shown, the second projection device 20 may be mounted on the roof of a vehicle to generate at least one obscuring projection surface 102 above a person's face to prevent external cameras from capturing images. In the current embodiment, the second projection device 20 may include a first projector 10 and a second projector 20, which together generate a three-dimensional projection surface. The obscuring projection surface can prevent external cameras from accurately capturing facial images, thereby reducing the facial recognition rate.

[0046] According to the present invention, the first projection device 10 and the second projection device 20 can each be responsible for different facial regions, thereby minimizing interference with the eyes. Therefore, combining the projections of the first projection device 201 and the second projection device 202 can improve the effectiveness of anti-face recognition.

[0047] According to the present invention, the anti-face recognition system 50 can be activated when the vehicle is started. Of course, the anti-face recognition system can also be activated manually or automatically based on environmental detection. However, as mentioned above, the cameras targeted by this invention are not those used for urban management. Therefore, it is advantageous to avoid "accidental blocking" of some cameras as much as possible.

[0048] Therefore, the anti-face recognition system 50 according to some embodiments of the present invention may further include a vehicle positioning module 16 and a traffic information module 18. The vehicle positioning module 16 can be any suitable positioning system, such as a GPS positioning system, a BeiDou positioning system, etc. The vehicle positioning module 16 can provide the current location of the vehicle. The traffic information module 18 can be a map module (e.g., a high-precision map) or a navigation module. Various traffic data are stored in the map module or navigation module. Furthermore, the traffic information module can also be a storage device storing traffic data transmitted from a remote server. The traffic information module may store information about the locations of various cameras, such as traffic camera locations.

[0049] The control device 14 can obtain the current vehicle location and traffic camera location from the vehicle positioning module and traffic information module, and control the projection of the interfering electromagnetic waves toward the face based on the obtained current vehicle location and traffic camera location. When the current vehicle location and traffic camera location are within a predetermined range, the control device outputs a first stop command to stop the first projection device from projecting the interfering electromagnetic waves toward the face. When the current vehicle location and traffic camera location are outside the predetermined range, the control device outputs a first enable command to enable the first projection device to project the interfering electromagnetic waves toward the face.

[0050] Alternatively, the control device 14 can also control the generation of the opaque projection surface based on the vehicle's current position and the traffic camera's position. For example, when the vehicle's current position and the traffic camera's position are within a predetermined range, the control device outputs a second stop command to stop the second projection device from generating the opaque projection surface. When the vehicle's current position and the traffic camera's position are outside the predetermined range, the control device outputs a second enable command to enable the second projection device to generate the opaque projection surface.

[0051] It should be understood that the control device can be configured as any device with data processing and analysis capabilities, including a processor. For example, the control device can be configured as one or more processors, or it can be configured as a computer, server, or even other smart handheld device. The processor can be connected to the storage module via an interconnect bus. The storage module can include main memory, read-only memory, and mass storage devices such as various disk drives, tape drives, etc. "Processor" is not limited to CPU or GPU; instead, it can include digital signal processor (DSP) hardware, network processors, application-specific integrated circuits (ASICs), and field-programmable gate arrays (FPGAs). The storage device can be read-only memory (ROM), random access memory (RAM), and non-volatile memory used to store software. Other conventional and / or custom hardware may also be included.

[0052] Next, refer to Figure 3 A flowchart describing in detail some embodiments of the anti-face recognition method according to the present invention.

[0053] like Figure 3 As shown, the anti-face recognition method may include: Step 210: Project interfering electromagnetic waves toward the face (of the user inside the vehicle), the interfering electromagnetic waves interfering with the recognition of the face, wherein the interfering electromagnetic waves are projected onto the area in front of the face. Step 220: Obtain the direction of eye gaze; and Step 230: Adjust the projection of the interfering electromagnetic waves toward the face according to the direction of the eye's gaze.

[0054] In step 210, the interfering electromagnetic waves can be projected onto the face area using the first projection device described above. In step 220, the eye-tracking device described above (e.g., a vehicle-mounted camera) can be used to detect the direction of eye gaze. In step 230, the projection of the interfering electromagnetic waves can be controlled using the control device described above.

[0055] Preferably, step 230 may include: Step 231: Adjust the projection direction of the interfering electromagnetic waves toward the face according to the acquired eye gaze direction, so as to at least partially avoid projection onto the eyeballs; and / or Step 232: Reduce the projection intensity of the interfering electromagnetic waves on the eye region at least partially based on the obtained eye gaze direction.

[0056] In step 231, the interfering electromagnetic wave can be configured to be rotatable and / or movable, so that the projection direction can be adjusted by rotating and / or moving the electromagnetic wave, so that the central axis of the electromagnetic wave is further away from the eye area, thereby reducing the amount of electromagnetic wave that falls directly into the eye.

[0057] In step 232, the interfering electromagnetic wave can be configured to have a variable projection intensity, thereby reducing the radiation intensity of the interfering electromagnetic wave as needed, thereby reducing the intensity of the electromagnetic wave that directly enters the eyeball.

[0058] Alternatively or additionally, the anti-face recognition method further includes: Step 250: Detect facial fatigue; and Step 260: When a fatigued state is detected on a face, an alert is issued.

[0059] Alternatively or additionally, the anti-face recognition method further includes: Step 240: Generate a occlusive projection surface, preferably a holographic projection surface, for use in face recognition by at least partially occluding the face.

[0060] In step 240, the aforementioned second projection device can be used to project a masking projection surface onto the face, thereby at least partially blocking the view from external cameras. According to the present invention, the first and second projection devices can each handle different facial areas, minimizing interference with the eyes. Therefore, combining the projections from the first and second projection devices can improve the effectiveness of anti-face recognition.

[0061] Alternatively or additionally, the anti-face recognition method further includes: Step 270: Obtain the vehicle's current location; Step 271: Obtain the location of traffic cameras; Step 272: Control the projection of the interfering electromagnetic waves toward the face based on the vehicle's current location and the location of the traffic camera.

[0062] Alternatively or additionally, the anti-face recognition method further includes: Step 273: Control the generation of the occlusive projection surface based on the vehicle's current position and the traffic camera's position.

[0063] Preferably, step 272 further includes: Step 274: Determine the distance between the vehicle's current position and the traffic camera's position. When the vehicle's current position and the traffic camera's position are within a predetermined range, stop the first projection device from projecting interfering electromagnetic waves toward the face, and... Step 275: When the vehicle's current position and the traffic camera's position are outside the predetermined range, activate the first projection device to project the interfering electromagnetic waves toward the face.

[0064] Preferably, step 273 further includes: Step 276: Determine the distance between the vehicle's current position and the traffic camera's position. When the vehicle's current position and the traffic camera's position are within a predetermined range, stop the second projection device from generating the obscuring projection surface. Step 277: When the vehicle's current position and the traffic camera's position are outside the predetermined range, activate the second projection device to generate the occlusive projection surface.

[0065] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection defined by this disclosure.
