Description

Technical Field

[0001] This invention relates to the field of phototherapy equipment technology, and in particular to a safety protection method, device, and head phototherapy system for a head light application device. Background Technology

[0002] Studies have shown that light of a certain wavelength can penetrate the human skull and stimulate cells to produce beneficial effects, thereby achieving the purpose of treating brain diseases. For example, some studies have shown that near-infrared light with a wavelength of 810nm can be used to treat Alzheimer's disease.

[0003] Light has a certain degree of penetrability and thermal effect. When using phototherapy devices, if the light irradiation mode is activated incorrectly or not at all, it can easily damage the user's vision. For example, near-infrared short waves can be absorbed by the lens and iris, causing cataracts. However, existing phototherapy products lack corresponding safety protection designs.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0063] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0064] Example 1

[0065] This invention provides a safety protection method for a head-mounted light application device, such as... Figure 1 As shown, the method includes:

[0066] S1. Acquire an image of the user wearing the head-mounted light application device;

[0067] The head light application device can be any device that can be worn on the head to apply light therapy, such as a head cap or helmet. For simplicity, it will be referred to as a head cap in the following text.

[0068] Images of the user wearing the headgear can be obtained directly from image acquisition devices such as cameras, or by remotely acquiring monitoring data of the user and selecting images from it. Preferably, one frame from a set of consecutively adjacent, identical frames is selected as the image of the user wearing the head-mounted light application device in this step. This reduces computational load and alleviates the backend burden. The user's actions during the headgear-wearing process are generally continuous, such as removing, putting on, and adjusting the headgear. If multiple consecutive frames are identical (similarity greater than a certain threshold), it is highly likely that the headgear-wearing action has ended.

[0069] A set of images with consistent multiple consecutive frames can be extracted at a certain preset interval. Then, gray-level correlation calculations can be performed on adjacent images on the time axis, such as comparing the gray-level distribution of adjacent images to roughly determine the time frame.

[0070] S2. Based on the acquired image, determine whether the head light application device meets the preset wearing standard;

[0071] The image of the user wearing the head light application device carries information about the user's head (including face) and headgear, as well as their relative positions. Based on this, it can be determined whether the headgear is worn in accordance with preset requirements, which can be reflected by the aforementioned preset wearing standards.

[0072] The preset wearing standards refer to the detailed requirements for correctly wearing a headgear, and generally correspond to the inspection items for headgear wearing. For example, the inspection items for checking whether a headgear is worn correctly may generally include:

[0073] Check if the hat is worn backwards.

[0074] Check if the bottom edge of the hat extends beyond the eyebrows or is within a certain preset range from the eyes (i.e., whether the hat is worn too high or too low).

[0075] Check if the center line of the hat is aligned with the center of the eyebrows or the middle of the eyes (i.e., whether the hat is not centered or is worn crookedly).

[0076] Check if the bottom edge of the hat is tilted (i.e., whether the left and right sides of the hat are level when worn).

[0077] If the headgear is equipped with an eye protection device, the inspection items may further include: checking whether the eye protection device is worn correctly? Preset wearing standards may include multiple preset conditions corresponding to the above inspection items. When the preset wearing standards include multiple preset conditions, the head light application device only meets the preset wearing standards when all preset conditions are satisfied.

[0078] Step S2 can be implemented in a variety of ways, and this disclosure does not limit it. The following examples are for reference only.

[0079] For example, this step can compare an image of the user wearing the head-mounted light application device with a standard wearing image to determine whether the head-mounted light application device meets a preset wearing standard. The standard wearing image is an image of the user correctly wearing the head-mounted light application device, preferably an image verified and confirmed by relevant personnel. For example, during the device debugging phase, relevant technicians can assist the user in taking a correct wearing image as the standard wearing image. By comparing the image with the standard wearing image, if the consistency exceeds a preset value, the head-mounted light application device is determined to meet the preset wearing standard, i.e., the headgear is worn correctly. Otherwise, there is a wearing problem and adjustment is needed.

[0080] For example, this step can also be implemented using an image classification-based artificial intelligence system. An image classification model, such as a convolutional neural network-based model, can be pre-trained. Training samples cover images of correctly worn hats that conform to preset wearing standards and images of various incorrectly worn hats that do not conform to the preset wearing standards. The acquired user image is input into the trained image classification-based artificial intelligence system, which outputs information on whether a hat is being worn and whether the hat wearing conforms to the preset wearing standards. If the hat does not conform to the preset wearing standards, the system outputs the corresponding incorrect wearing classification.

[0081] For example, this step can also obtain relevant information about the current user's headgear through image recognition, and determine whether it meets the preset wearing standards.

[0082] Additionally, it should be noted that step S2 can be implemented on the user's side, or it can be implemented on the server side by uploading an image of the user wearing the head-mounted light application device to the server. The server can determine whether the user's wearing of the head-mounted light application device meets the preset wearing standards based on the uploaded image, and then send the determination result to the user's side.

[0083] S3. When the head light application device meets the preset wearing standard, activate the optical module of the head light application device, or place the head light application device in the unlocked state where light can be applied.

[0084] When the headgear is determined to meet preset requirements, this step can automatically activate the optical module of the head light application device to apply light; alternatively, the head light application device can be unlocked from its locked state to allow it to apply light. In the latter case, if a command to activate phototherapy or other light application is received while the device is in the unlocked state, the optical module will automatically activate to apply light.

[0085] This invention uses images of a user wearing a head-mounted light application device to determine whether the device meets preset requirements. Only when the device meets these requirements can its optical module be activated or placed in an unlocked state capable of applying light. This significantly reduces the likelihood of safety hazards caused by improper wear. This solution enables intelligent automatic wear detection.

[0086] It should be noted that the head light application device in this disclosure can be used to apply any light capable of phototherapy to the user's head, including but not limited to transcranial light capable of treating brain diseases.

[0087] This embodiment also provides another safety protection method for a head-mounted light application device, as shown in Figure 2(a), wherein step S2 of the method includes:

[0088] S21. Perform image recognition on the acquired image of the user wearing the head light application device;

[0089] S22. Extract the wearing information of the head light application device contained in the image;

[0090] S23. Then, based on the wearing information, determine whether the head light application device meets the preset wearing standard.

[0091] Specifically, the wearing information of the head light application device needs to reflect the current user's headwear wearing status, and in step 23, this information can be used to determine whether the current user's headwear wearing conforms to the preset wearing standard. It is understood that there is a correspondence between the wearing information of the head light application device and the preset wearing standard; that is, different preset wearing standards may correspond to different wearing information that needs to be extracted.

[0092] For example, if the preset wearing standard includes that the lower edge of the hat should not exceed the user's eyes, then the corresponding wearing information to be extracted includes: the position information of the user's eyes and the position information of the lower edge of the hat. Correspondingly, in step S21, the user's eyes and the lower edge of the hat are identified using image recognition technology; in step S22, the position information of the eyes and the lower edge of the hat is extracted; and then, in step S23, based on the position information of these two elements, it is determined whether the lower edge of the hat is lower than the eyes. Those skilled in the art will understand that steps S21 and S22 can also be combined into one step.

[0093] In addition, it should be noted that even if the preset wearing standards are the same, there are multiple implementation schemes. Therefore, the wearing information extracted in this embodiment is not specifically limited.

[0094] Generally, the extracted wearing information includes at least one of the facial feature position information and one feature position information of the head light application device. Incorrect wearing of the head light application device is most likely due to it being worn backwards, too low or too high, or bent at an angle. These wearing errors can be determined based on the positional relationship between the headgear and the face. Therefore, at least one of the facial feature position information is generally needed to characterize the face position, and at least one feature position information of the head light application device is needed to characterize the headgear position.

[0095] Among the facial feature location information, the preferred location information is the eye position, and among the feature location information of the head light application device, the preferred location information is the lower edge of the front of the headgear. If the location information of the user's eyes and the lower edge of the front of the headgear can be extracted from the image through image recognition, the various wearing detection items in the headgear wearing inspection mentioned above can be realized.

[0096] In some embodiments, the extracted facial feature information may include, in addition to the positional information of the eyes, the positional information of the eyebrows and nose. It may also include the positional information of the mouth, facial contours, etc.

[0097] In some embodiments, the extracted feature location information of the head light application device may also include the location information of the outline of the head light application device, or the location information of the lower edge of the front end; or other features. As long as this or these feature location information can be combined with facial feature information to determine whether the headgear is worn.

[0098] In some embodiments, the head-mounted light application device further includes an eye protection device worn over the eyes. In this case, the extracted feature location information of the head-mounted light application device also includes the location information of the eye protection device. The location information of the eye protection device is used to determine whether the eye protection device is worn correctly, thereby providing more comprehensive safety protection. Accordingly, the preset wearing standard further includes whether the relative position of the eye protection device to the eyes is within a preset range. The eye protection device may be, for example, infrared protective glasses.

[0099] In some embodiments, the extracted wearing information includes: eye position information; and the position information of the front feature points, lower edge, and midline of the head light application device. The preset wearing standard includes the following preset conditions:

[0100] Whether the front feature point of the head light application device is located above the eyes (this is used to check whether the headgear is worn backwards);

[0101] Whether the lower edge of the head light application device is within the preset range from the eyes (this is used to check whether the headgear is worn too high or too low; too low can easily damage the eyes, while too high will affect the phototherapy effect).

[0102] Whether the center line of the head light application device is aligned with the middle of the wearer's eyes (this is used to check whether the headgear is not centered and is tilted to one side);

[0103] The lower edge of the head light application device is tilted at an angle relative to the line connecting the eyes, which does not exceed the preset angle value (this is used to check whether the headgear is worn evenly on both sides, and whether one side is higher than the other).

[0104] In step S23, it is determined whether the extracted front end, lower edge, and center line feature position information meet the preset conditions in the preset wearing standard. When all the above preset conditions are met, the headgear is worn correctly, and the optical module of the head light application device is turned on or off.

[0105] This embodiment determines whether the preset conditions in the wearing standard are met one by one based on the above wearing information. This can eliminate most cases of incorrect wearing and improve the safety of using the head-mounted light application device. Alternatively, the wearing information can be scored based on the satisfaction of each preset condition (e.g., the difference value), then weighted to give the final judgment result. The specific weighting value can be determined according to the importance of each preset condition.

[0106] In some other embodiments, the preset wearing standard may include one or more of the preset conditions mentioned above. Accordingly, depending on the preset conditions included in the preset wearing standard, the extracted wearing information may include the front end, lower edge, and midline position information of the head light application device, etc.

[0107] In some embodiments, as shown in FIG2(b), when it is determined that the head-mounted light application device does not meet the preset wearing standard, the method further includes:

[0108] S31. Obtain the status information of the optical module of the head light application device;

[0109] S32. Determine whether the above status information is in an open state or an unlocked state that allows opening;

[0110] S33. When the status information is in the open state or the unlocked state that allows opening, turn off the optical module or put the optical module in the locked state that does not allow opening.

[0111] The safety protection method of this embodiment detects that the wearing of the head light application device does not meet the preset wearing standard (at least part of the head light application device is about to be removed or has been removed from the head). It checks the status of the optical module. If the optical module is in the open state, it is turned off (if the optical module is in the unlocked state that allows it to be opened, it is placed in the locked state that does not allow it to be opened). This avoids the optical module remaining in the open state when the head light application device is removed from the head, thereby causing harm to the user or a third party.

[0112] Furthermore, image-based wear detection is continuously performed throughout the phototherapy process. This means that images of the user wearing the head-mounted light application device are acquired in real-time during the treatment, and the device's fit is assessed against preset wearing standards. If any non-compliance is detected, the optical module is immediately shut down or locked in a prohibited state. This method ensures that the optical module shuts down immediately if the user attempts to remove the head-mounted light application device, preventing harm to the user or any third party even in the event of an erroneous removal.

[0113] It is understandable that after the optical module is turned off or locked in a state where it cannot be opened, the steps of acquiring images of the user wearing the head light application device and determining whether it meets the preset wearing standards can continue to be executed, so as to realize real-time monitoring of the headgear wearing status throughout the phototherapy process. In another embodiment, the phototherapy process can also be considered to be over after the optical module is turned off or locked in a state where it cannot be opened, and the steps of acquiring images of the user wearing the head light application device and determining whether it meets the preset wearing standards will no longer be executed, so as to save resources. If the user needs to restart the phototherapy process, other control signals need to be used to trigger the steps of acquiring images of the user wearing the head light application device and determining whether it meets the preset wearing standards.

[0114] In some embodiments, when the head light application device does not meet the preset wearing standard, the method further includes: generating and providing targeted prompts to the user to adjust the wearing of the head light application device based on the acquired image.

[0115] For example, if the feature position of the hat is not extracted during the wearing judgment, the user is prompted to wear the hat. If the extracted lower edge is less than the preset value from the eyes, the user is prompted that the hat is too low and needs to be moved up for adjustment.

[0116] Example 2

[0117] The present invention provides a safety protection method for a head light application device, which differs from the scheme described in Embodiment 1 in that the wearing information extracted in step S2 of this embodiment includes at least two items of facial feature position information, one of which serves as the primary basis for judging whether the head light application device meets the preset wearing standard, and the remaining items serve as alternative basis when the primary basis cannot be extracted, or as the verification basis for the judgment result generated based on the primary basis.

[0118] For example, the extracted eye position information can be used as the primary criterion to determine whether the hat is worn correctly based on the eye position information and the hat-related position information. Simultaneously, either eyebrow or nose position information can be extracted as a secondary criterion. If the eye position information, as the primary criterion, is successfully extracted, the eyebrow or nose position information is used to verify the above judgment result. There are various verification algorithm designs. For example, the extracted eye position information can be calculated based on the eyebrow or nose position information to determine whether it is within the allowable error range. Alternatively, the hat-wearing accuracy can be determined directly based on the eyebrow or nose position information and the extracted hat-related position information; if the judgment results are consistent, the verification passes.

[0119] The following description, in conjunction with the accompanying drawings, illustrates this embodiment.

[0120] like Figure 3 As shown, the security protection method provided in this embodiment includes:

[0121] S1. Obtain an image of the user wearing a hat;

[0122] S221. Perform image recognition and wear information extraction on the acquired image;

[0123] S222. Determine whether the facial feature position information (e.g., eye position information) used as the primary basis has been extracted; if extracted, proceed to step S223; if not extracted, proceed to step S226.

[0124] S223. Based on the facial features position information as the primary basis and the extracted head and hat position information, determine whether the head and hat wearing meets the preset standards.

[0125] S224. If it meets the criteria, determine whether the positional information of the facial features (such as the positional information of the eyes or nose) has been extracted as a candidate.

[0126] S225. If extracted, the judgment result is verified based on the facial feature location information (such as the location information of the eyes or nose) used as alternative criteria.

[0127] If the verification is successful, proceed to step S3 to turn the optical module on or off; if there is a problem with the verification, notify the user that there is a problem and ask the user to confirm before proceeding to step S3. Alternatively, you can only remind the user of security when the optical module is turned on or off.

[0128] S226. Determine whether the positional information of the facial features (such as the positional information of the eyes or nose) has been extracted as a candidate basis; if it has been extracted, proceed to step S227; if it has not been extracted, proceed to step S228.

[0129] S227. Determine whether the preset wearing standard is met based on the alternative criteria and information related to the headgear position; if yes, proceed to step S3, and you can choose to inform the user that only the alternative criteria were retrieved and not verified; if no, proceed to step S4.

[0130] S228. Prompt the user that the information retrieval failed; Step S228 ends, continue to step S4.

[0131] S4. Remind the user to wear the hat correctly and face the image acquisition device;

[0132] Step S4 ends, and step S1 can be executed.

[0133] When a headgear is incorrectly worn, the process of acquiring images, extracting wearing information, and determining whether the headgear is worn correctly can be executed repeatedly.

[0134] In some embodiments, the extracted wearing information may include: position information of the eyes, eyebrows, and nose; wherein, the eye position information may be used as the primary basis; one of the eyebrow and nose position information may be used as the alternative basis; and the eyebrow and nose position information that is not used as an alternative basis may be used as the verification basis for the judgment result.

[0135] In actual headgear wearing detection, the head light application device may be equipped with eye protection devices, such as infrared goggles or a protective shield. When the user is wearing the headgear, the eye protection device often covers their eyes. This can lead to the following situations: if the eye position information can be obtained, but the headgear is not worn properly, the wearing detection fails; conversely, once the user is wearing the headgear properly, the eye position information cannot be obtained, and the detection still fails.

[0136] In this embodiment, when the eye position information, which is the primary basis, cannot be extracted, the eyebrow or nose position information, which is the alternative basis, can be used to make a judgment, thereby solving the above problem and improving the pass rate when wearing the correct garment.

[0137] In some embodiments, if the eye position information, which is the primary criterion, cannot be obtained, but the eyebrow or nose position information, which is a candidate criterion, can be obtained, the eye position information can be obtained based on the eyebrow or nose position information, and then a judgment can be made. Specifically, before determining whether the head-mounted light application device meets the preset wearing standard based on the wearing information, the following steps are also included:

[0138] The user image is acquired. The user image can be preset or acquired in real time. It is required to include the current user's facial image, and at least the eyes and eyebrows, or the eyes and nose, are included at the same time.

[0139] Extract the relative position information of the eyes and eyebrows, or the relative position information of the eyes and nose in the user's image;

[0140] Based on at least one of the aforementioned relative position messages, and the position information of the eyebrows or nose, calculate the position information of the eye as the primary basis.

[0141] The relative position information of the user's eyes and eyebrows (or eyes and nose) can also be pre-stored. The position information of the eyes can be calculated directly based on the pre-stored relative position information, that is, based on the position information of the eyebrows or nose. Then, it can be directly used to determine whether the preset wearing standard is met. This solution is particularly suitable for situations where the wear detection cannot be passed even if the eye protection device is worn correctly because it obstructs the eyes.

[0142] Furthermore, in some embodiments, the alternative criteria may include multiple criteria, and the selection order of multiple alternative criteria can be set according to actual needs. For example, the alternative criteria include a first alternative criterion and a second alternative criterion, where the first alternative criterion is the preferred choice when the primary criterion cannot be extracted, and the second alternative criterion is the preferred choice when neither the primary criterion nor the first alternative criterion can be extracted.

[0143] The extracted wearing information includes the position information of the eyes, eyebrows, and nose; wherein, the eye position information serves as the primary criterion; one of the eyebrow and nose position information serves as the first alternative criterion, and the other can serve as the second alternative criterion. In one embodiment, the eyebrow and nose position information that is not used as an alternative criterion can also serve as the verification criterion for the judgment result.

[0144] Among the extracted facial features, eye position information is the first choice, but it may be obscured; eyebrow position information is the second choice, but some elderly people may have sparse eyebrows, making extraction difficult. In this case, nose position information can be set as a second alternative. Similarly, if needed, eye or eyebrow position information can also be obtained through nose position information.

[0145] This embodiment can solve the problem of not being able to extract wearing information due to obscuring facial features or other reasons, and can improve the pass rate when wearing correctly.

[0146] Example 3

[0147] The present invention provides a safety protection method for a head-mounted light application device, which differs from the scheme described in Embodiment 1 or 2 in that, when obtaining at least one feature location information of the head-mounted light application device through image recognition, it is obtained in the following manner:

[0148] Image recognition is used to extract the position information of the marking pattern on the head light application device; the feature position information is obtained based on the position information of the marking pattern.

[0149] Identifying a hat and extracting its feature location information from an image remains challenging for computers, especially given system resources and time constraints. For example, how can a computer determine that it is a hat and not another object? How can it identify the portion of a hat above the face in an image as the front part that should be worn on one side of the face, rather than other parts? Designing markings such as lines, dots, or graphics on the outer surface of the hat can reduce the difficulty of image recognition, such as decreasing the amount of backend computation, and also facilitate the acquisition of more accurate feature location information, thus improving the accuracy of the wearing identification.

[0150] The markings designed on the outer surface of the headgear can be a different color from the headgear itself; for example, if the headgear is black, the markings could be red. During image recognition, by simply filtering out the red graphic and combining its position and shape in the image, it is easy to determine whether it is a marking pattern, and thus determine whether the headgear is being worn. The position of this red graphic can be extracted as feature position information of the head light application device; furthermore, based on the position of the red graphic, other feature position information or other wearing information can be calculated. For example, based on the design position of the red graphic on the headgear, it is possible to deduce whether the front of the headgear is currently worn above the face, the position of the lower edge, etc.

[0151] The number, position, and specific shape of the marking patterns can be set according to the preset wearing standards. This disclosure does not limit this, as long as it can be used together with the extracted facial feature position information to complete the headwear wearing judgment.

[0152] For example, to check if a hat is worn backwards or askew, a center line bisecting the front of the hat can be designed as a marker. By detecting the presence of this center line in the user's wearing image, it can be determined whether the user has placed the front end with the center line on their forehead. Furthermore, by checking if the center line in the image is aligned with the center of the user's eyes, it can be determined whether the hat is misaligned or worn crookedly, thus judging whether the hat is worn according to standards. The center of the eyes mentioned above can be calculated using eye position information.

[0153] For example, the end of the phototherapy headgear should not be lower than the brow bone (for eye safety and positioning during wear). A warning line can be placed at a preset distance from the bottom of the phototherapy module at the front of the headgear as an indicator. This warning line can be a different color from the headgear and parallel to the bottom edge of the headgear. When determining if the headgear is worn correctly, the warning line is first identified by its color, and then it is directly judged whether the warning line does not exceed the eyebrows or whether the distance between the warning line and the eyes does not exceed a preset threshold. If so, the headgear is worn according to the corresponding item in the correct wearing standard. The distance between the warning line and the eyebrows or eyes can determine whether the headgear is worn too low or too high. The warning line can also detect whether the user has worn the headgear backwards.

[0154] By comparing the distance between the warning line and the two eyes, it can be determined whether the headgear is worn at an angle, that is, whether the left and right sides of the headgear are level when worn, and whether there is a problem that the lower edge is higher on one side and lower on the other.

[0155] By comparing whether the midpoint of the warning line is aligned with the position between the eyebrows or between the eyes, it can be determined to some extent whether the headgear is not centered.

[0156] In summary, by using marked patterns, one or more feature positions of the headwear needed to determine whether it is worn can be obtained, which can reduce the difficulty and computational load of image recognition and improve the reaction speed.

[0157] Alternatively, marking lines can be placed around the edge of the eye protection device to reduce the difficulty of identifying it.

[0158] Example 4

[0159] This invention provides a safety protection method for a head-mounted light application device. The difference between this method and the schemes described in embodiments one to three is that it provides a triggering condition for the detection step S1 (acquiring an image of the user wearing the head-mounted light application device). When the triggering condition is met, step S1 is executed.

[0160] That is, before acquiring an image of the user wearing the head-mounted light application device, such as Figure 4 As shown, it also includes:

[0161] S7. Obtain information on whether the head-mounted light application device has been worn by the user;

[0162] S8. When it is possible to obtain information that the head light application device has been worn, or when it can be determined that the head light application device has been worn, the step S1 of obtaining an image of the user wearing the head light application device is executed.

[0163] In this embodiment, when the system detects that the user has put the headgear on their head, the image acquisition device begins to acquire the user's image and determines whether the headgear fits according to a preset standard. For example, a sensor, such as a pressure sensor or others, can be installed on the headgear. When the sensor detects that the headgear is being worn, the power is turned on, and the image acquisition device begins to acquire the user's image. Alternatively, the user can directly input information that the head light application device is being worn.

[0164] Before acquiring an image of the user wearing the head-mounted light application device, such as Figure 5 As shown, it also includes:

[0165] S5. Obtain information on whether the head-mounted light application device has been removed from the bracket mounting position;

[0166] S6. When information is obtained that the head light application device has been removed, or when it can be determined that the head light application device has been removed, step S1 of obtaining an image of the user wearing the head light application device is executed.

[0167] In this embodiment, when the system detects that the user has removed the headgear from the bracket's mounting position, the image acquisition device begins to acquire the user's image and determines whether the headgear's fit meets a preset standard. For example, a sensor, such as a gravity sensor or others, can be installed at the headgear's mounting position on the bracket. When the sensor detects that the headgear has been removed, the power is turned on, and the image acquisition device begins to acquire the user's image. Alternatively, the user can directly input information that the head light application device has been removed.

[0168] Furthermore, when the system detects that the user has removed the head-mounted light application device from the bracket's mounting position, it provides guidance to the user based on the progress of the user's operation, enabling the user to quickly and correctly put on the headgear. Preferably, the guidance is provided through voice, or a combination of voice and visuals.

[0169] Users simply need to turn on the power (this step can be omitted), remove the headgear, and then complete the wear detection under voice guidance before phototherapy. It is safe, user-friendly, and simplifies the operation, making it convenient for the elderly to use.

[0170] Example 5

[0171] This invention provides a safety protection method for a head-mounted light application device, which differs from the solutions described in embodiments one to four in that, as Figure 6As shown, this embodiment further includes, before activating the optical module of the head light application device or placing the head light application device in an unlocked state capable of applying light:

[0172] S9. Steps for authenticating users;

[0173] In step S3, when the user is authenticated and the head light application device meets the preset wearing standards, the optical module of the head light application device is turned on, or the head light application device is placed in an unlocked state that can apply light.

[0174] Step S9, which verifies the user's identity, can be performed before, after, or simultaneously with the headwear wearing detection, as long as the user is authenticated before the optical module of the head light application device is turned on or off. This solution enables user authentication while detecting headwear wearing, preventing potential dangers caused by individuals with limited mobility, such as children or elderly people with cognitive impairments, using head light application products.

[0175] Step S9, which verifies user identity, can be implemented in various ways, such as fingerprint recognition, facial recognition, and voiceprint recognition. Facial recognition or fingerprint recognition is preferred for step S9 as it is simple, easy to use, and more suitable for the elderly.

[0176] For example, step S9 may include: acquiring a user image; performing identity recognition based on the acquired user image to determine whether the current user is an authorized user; when it is determined that the current user is not an authorized user, turning off the head light application device and no longer proceeding with the process of whether the head light application device meets the preset wearing standard.

[0177] Furthermore, in some embodiments, when it is determined that the current user is not an authorized user, the head light application device is directly turned off, which can prevent people without behavioral capacity, such as children or elderly people with cognitive impairment, from turning on the head light application device out of curiosity and causing danger.

[0178] In some embodiments, the authorized users who can pass authentication include legitimate users and temporarily authorized users. Legitimate users are those with administrator privileges or authorized by an administrator who can legitimately use the head light application device, and their privileges are generally not time-limited. Legitimate users can be pre-set by providing a list of legitimate users. Temporarily authorized users are those who have not obtained legitimate use of the head light application device through pre-setting, but have been authorized by an administrator or other legitimate users to temporarily use the head light application device for a certain period of time.

[0179] Determining whether the current user is an authorized user includes: checking if the current user is in the list of authorized users; if the current user is not in the list of authorized users, sending a temporary authorization request to the administrator, and marking the current user as a temporarily authorized user or an unauthorized user based on the administrator's response.

[0180] The administrator's response also includes: whether to provide an instruction to monitor the current user; when receiving an instruction to monitor the current user, sending the monitoring image of the current user and the status parameters of the head light application device to the administrator, temporarily authorizing the user to use the device, and the administrator can stop the operation of the device at any time or provide timely usage guidance.

[0181] When granting temporary authorization, the administrator can choose whether to monitor the temporarily authorized user. If monitoring is selected, the administrator can obtain the monitoring image of the current user and the status parameters of the head-mounted light application device. If misuse or other situations requiring emergency shutdown are detected, the administrator can directly shut down or stop the light application remotely, thus preventing dangers caused by improper operation by temporarily authorized users. The administrator can designate one or more users from the list of authorized users.

[0182] In this embodiment, users who are capable of independent and safe use of the head-light application device can be designated as administrators or authorized users. These users can use the head-light application device independently. Elderly people who need but lack the ability to use the head-light application device independently and safely can use it under supervision through temporary authorization. Meanwhile, other users who do not need to use the device, such as children, can be excluded during identity verification.

[0183] Furthermore, certain special users can be set to be blacklisted and prohibited from use, such as children in the family. If a blacklisted user is detected during identity verification, the device will be shut down and the administrator will be notified, and no temporary authorization request will be sent to the administrator.

[0184] In summary, this embodiment combines identity authentication with photo-based wear detection, resulting in enhanced security and preventing potential dangers from individuals with limited mobility, such as children or elderly people with cognitive impairments, using the light application device. The light application device could be, for example, a head-mounted phototherapy product.

[0185] The following description uses some specific examples to illustrate the point.

[0186] like Figure 7 The diagram shown is a flowchart of a security protection method including authentication provided in this embodiment, used in a phototherapy helmet. The method includes:

[0187] Real-time acquisition of user monitoring data;

[0188] The acquired monitoring data is subjected to facial recognition detection. When a face is detected, an identity verification step is performed; when no face is detected, new monitoring data is acquired.

[0189] Based on the identity verification results, determine whether the current user has a legitimate identity; if so, verify the helmet and eye protection device.

[0190] Based on the recognition results of the previous step, determine whether the user is wearing a helmet; if the user is wearing a helmet, determine whether the helmet is worn correctly (i.e. whether the preset wearing standard is met); if the helmet is not recognized or the helmet is not worn on the user's head, prompt the user to wear a helmet, and after a preset time (e.g., the estimated time required for the user to wear a helmet), obtain the latest monitoring data and return to the helmet and eye protection device recognition step.

[0191] In determining whether the helmet is worn correctly, if the helmet is correctly worn (meeting the preset wearing standard), the system continues to determine whether the eye protection device (if equipped) is worn and whether it is worn correctly (meeting the preset wearing standard for the eye protection device). If the helmet is incorrectly worn (not meeting the preset wearing standard), the system prompts the user to wear the helmet correctly, retrieves the latest monitoring data after a preset time, and returns to the helmet and eye protection device identification steps.

[0192] If the eye protection device is determined to be worn correctly, other activation or deactivation conditions of the optical module (e.g., infrared module) of the phototherapy helmet are checked. These other activation or deactivation conditions could include power voltage detection, temperature detection, etc. If all conditions are met, the optical module of the phototherapy helmet is activated or deactivated. If not, the user is prompted to wait for a period of time before another activation or deactivation test is performed. If the conditions are still not met after the second test, the device is powered off or awaits user instructions.

[0193] Determine if an activation command for the optical module has been received. If so, activate the optical module and initiate phototherapy; otherwise, continue searching for activation commands and prompt the user.

[0194] Determine if a shutdown command for the optical module has been received or if the preset phototherapy time has been reached. If so, shut down the optical module and end the process; otherwise, proceed to the step of returning to helmet and eye protection device recognition.

[0195] Furthermore, after the optical module is turned on or off, if the helmet or eye protection device is detected to change from being worn correctly to not being worn or incorrectly worn, the optical module will be immediately deactivated. If the optical module was originally only unlocked and not turned on, it will be changed from the unlocked state to a locked state that cannot be opened even with an activation command.

[0196] like Figure 8As shown, this embodiment also provides a flowchart of another security protection method including authentication, which is consistent with... Figure 7 The difference in the illustrated embodiment is that, in this embodiment, a sensor is installed on the strap or the head-mounted light application device. When the sensor outputs a signal indicating that the strap is engaged or other signals indicating that the helmet is worn, the image acquisition device is triggered to obtain monitoring data. Subsequent processes do not require helmet wearing detection; only the correctness of helmet wearing is checked.

[0197] Additionally, during the identity verification phase, if an unauthorized user chooses not to apply for temporary authorization, they will be recorded in the list of unauthorized identities. If the user attempts to verify their identity again during the current device activation phase or within a similar period, they will no longer request temporary authorization from a legitimate user or administrator. Instead, they will be treated as an unauthorized user, and the head light application device will be turned off or locked.

[0198] When a legitimate user or administrator responds to a temporary authorization request, they can choose to add the requesting user to a blacklist. Users on the blacklist (e.g., children in the household) will be checked after the legitimate user list during authentication. Once a user is identified as being on the blacklist, they will no longer be given the opportunity to request temporary authorization, and the head light application device will be immediately shut down. During authentication, the temporary authorization list and the illegitimate user list are checked after the blacklist. These lists can be set to be cleared upon each power-off or after a predetermined period following the current device power-off. This way, during the valid period when these lists are not cleared, there is no need to repeatedly send temporary authorization requests to legitimate users or administrators; authentication can be directly approved or rejected based on the lists.

[0199] Example 6

[0200] This invention provides a safety protection device 100 for a head-mounted light application device 10, such as... Figure 9 As shown, the device includes:

[0203] The control module 13 is used to turn on the head light application device 10 when the head light application device 10 meets the preset wearing standard, or to put the head light application device 10 into an unlocked state that can apply light.

[0204] The safety protection device in this embodiment can determine whether the wearing of the head light application device meets the requirements based on the collected user image, and ensure that the head light application device is in a safe state when applying light to the head.

[0205] Furthermore, such as Figure 10 As shown, the safety protection device in this embodiment further includes: a first sensing unit 14, used to obtain information on whether the head light application device has been removed from the hanging position of the bracket; when the information that the head light application device has been removed is obtained, the image acquisition device 11 performs the step of acquiring an image of the user wearing the head light application device 10, and performs wearing detection.

[0206] Or, such as Figure 11 As shown, the safety protection device further includes: a second sensing unit 15, used to obtain information on whether the head light application device has been worn by the user; when the information that the head light application device has been worn is obtained, the image acquisition device 11 performs the step of acquiring an image of the user wearing the head light application device, and performs wearing detection.

[0207] The safety protection device in this embodiment allows users to complete the wearing detection simply by removing or wearing the headgear, followed by phototherapy. It is safe, user-friendly, and easy to operate, making it suitable for the elderly.

[0208] Furthermore, such as Figure 12 As shown, the security protection device may further include: an identity authentication module 16 for authenticating the user; when the user is authenticated and the head light application device meets the preset wearing standard, the control module activates the optical module of the head light application device, or places the head light application device in an unlocked state that can apply light.

[0209] Furthermore, the security protection device may also include: a voice module, used to provide guidance to the user according to the user's operation process progress, so that the user can quickly pass identity verification and correctly wear the headgear, etc.

[0210] like Figure 13 As shown, this embodiment also provides another safety protection device 100 for a head light application device, including a memory 102 and a processor 101. The memory 102 stores a program 103, which is executed by the processor 101 to perform any of the safety protection methods described above.

[0211] A specific example of the security protection device 100 in this embodiment can be a tablet computer or other electronic device with an image acquisition device, such as a mobile phone or computer, that stores program 103. The image acquisition device of the tablet computer or other electronic device acquires the user's image, and the logic processing unit performs identity verification and / or wear detection according to the process of program 103.

[0212] This embodiment also provides a readable storage medium, see reference. Figure 13 As shown, the readable storage medium stores a program 103, which is executed by a processor to perform the security protection method as described in any of the preceding claims.

[0213] This embodiment also provides a head phototherapy system, including: a head light application device, and the safety protection device described in any one of the above.

[0215] In this embodiment, the head-light application device determines whether the wearing of the device meets preset requirements based on an image of the user wearing it. Only when the wearing meets the preset requirements can the head-light application device be activated or placed in an unlocked state capable of applying light, thus largely avoiding safety hazards caused by improper wearing. Furthermore, the head-light application device in this embodiment can also perform user authentication, preventing dangerous situations caused by incapacitated individuals such as children using the device.
