[0033] See also Figure 1 The security monitoring method for an aging-friendly space provided in the embodiments of the present application includes but is not limited to the following steps:

[0034] In S100, image information outside the door is obtained based on a preset camera.

[0035] Without loss of generality, the camera can be pre-installed outside the aging-friendly space. The camera's shooting range may include the area corresponding to the door opening of the aging-friendly space. The camera is used to shoot the situation outside the door. The number of cameras is not limited, and the number of cameras can be 1, 3 or other any other positive integers; the outside door image information is used to describe the image outside the door of the aging-friendly space.

[0036] Specifically, the terminal device can first obtain image information outside the door based on the camera.

[0037] In S200, the real-time facial information of the object outside the door is determined based on the image information outside the door and a preset face extraction algorithm.

[0038] Without loss of generality, the object outside the door is used to describe the person located outside the doorway of the aging-friendly space; the face extraction algorithm can be a Viola-Jones face detection algorithm, a face extraction algorithm based on MTCNN (Multi-task Cascaded Convolutional Networks), a face extraction algorithm based on SSD (Single Shot MultiBox Detector), a face extraction algorithm based on Faster R-CNN, or a face extraction algorithm based on RetinaFace; the real-time facial information is used to describe the real-time face of the object outside the door.

[0039] Specifically, after the terminal device obtains the image information outside the door, the terminal device can effectively determine the real-time facial information of the object outside the door in the image information outside the door based on the image information outside the door and a preset face extraction algorithm.

[0040] In S300, a preset facial database is searched based on the real-time facial information to determine the risk identity information of the person outside the door.

[0041] Without loss of generality, the facial database pre-stores multiple registered facial information, and the registered facial information is used to describe the face of the registered person. For example, the registered facial information may include the face of the guardian and the face of the elderly person's family member; the risk identity information includes safe identity information and dangerous identity information, among which the safe identity information is used to describe that the identity of the object outside the door is relatively safe and is not an attempted intruder, and the dangerous identity information is used to describe that the identity of the object outside the door is relatively dangerous and is an attempted intruder.

[0042] Specifically, the terminal device can search the facial database based on the real-time facial information, determine whether there is registered facial information corresponding to the real-time facial information in the facial database, and determine the risk identity information of the object outside the door.

[0043] Exemplarily, when there is registered facial information corresponding to the real-time facial information in the facial database, the terminal device can determine that the risky identity information of the object outside the door is safe identity information.

[0044] In S400 , if the risk identity information is dangerous identity information, the relative position information and the residence time information of the object outside the door are obtained.

[0045] Without loss of generality, the relative position information is used to describe the position of the object outside the door relative to the door opening of the aging-friendly space; the residence time information is used to describe the time the object outside the door stays outside the door opening of the aging-friendly space.

[0046] Specifically, if the risk identity information is dangerous identity information, the terminal device can obtain the relative position information and residence time information of the object outside the door.

[0047] In some possible implementations, to improve the effectiveness of relative position information and dwell time information, see Figure 2 Step S400 includes but is not limited to the following steps:

[0048] In S410, based on the preset super-sensing intelligent sensor, the three-dimensional contour information of the object outside the door and the door opening contour information of the target room are obtained.

[0049] Without loss of generality, the super-sensing intelligent sensor can be pre-installed in the wall outside the aging-friendly space. The super-sensing intelligent sensor can sense millimeter-level micro-movements and actively sense the presence of the human body. That is, the super-sensing intelligent sensor can accurately sense the specific position or movement trajectory of the human body based on millimeter-level micro-movements of the human chest during breathing. In one possible implementation method, the super-sensing intelligent sensor can be a radar sensor; the three-dimensional contour information is used to describe the three-dimensional contour constructed for the object outside the door, wherein the three-dimensional contour information includes multiple object contour point information; the doorway contour information is used to describe the three-dimensional contour constructed for the doorway of the target room, wherein the doorway contour information includes multiple room contour point information, and the target room is the aging-friendly space.

[0050] Specifically, the terminal device can obtain the three-dimensional contour information of objects outside the door and the door opening contour information of the target room based on the super-sensing intelligent sensor. Among them, the construction of the three-dimensional contour based on the radar sensor is an existing technology, so it will not be repeated.

[0051] In S420 , for each object contour point information: according to a preset Euclidean distance calculation function, the Euclidean distance information between the object contour point information and each room contour point information is calculated in sequence to generate Euclidean distance set information.

[0052] Specifically, the terminal device can perform this processing on the contour point information of each object: according to the preset Euclidean distance calculation function, the Euclidean distance information between the object contour point information and the contour point information of each room is calculated in sequence to generate Euclidean distance set information, wherein the Euclidean distance set information includes multiple Euclidean distance information.

[0053] Exemplarily, the Euclidean distance calculation function may be:

[0054]

[0055] Where ρ represents the Euclidean distance information, X2 represents the horizontal coordinate of the object contour point information in the left-right direction in the constructed three-dimensional model, Y2 represents the horizontal coordinate of the object contour point information in the front-back direction in the constructed three-dimensional model, Z2 represents the vertical coordinate of the object contour point information in the constructed three-dimensional model, X1 represents the horizontal coordinate of the room contour point information in the left-right direction in the constructed three-dimensional model, Y1 represents the horizontal coordinate of the room contour point information in the front-back direction in the constructed three-dimensional model, and Z1 represents the vertical coordinate of the room contour point information in the constructed three-dimensional model.

[0056] In S430 , relative position information of the object outside the door is determined based on the Euclidean distance set information.

[0057] Specifically, the relative position information is used to describe the Euclidean distance information with the smallest value in the Euclidean distance set information; the terminal device can determine the minimum value in the Euclidean distance set information based on the Euclidean distance set information to determine the relative position information of the object outside the door.

[0058] In S440, after a preset time interval, the re-detected position information of the object outside the door is obtained.

[0059] Specifically, the re-checked position information is used to describe the relative position information determined again after a preset time interval; the terminal device obtains the re-checked position information of the object outside the door after the preset time interval. The specific method of obtaining the re-checked position information of the object outside the door can refer to the relevant content in steps S410 to S430, so it will not be repeated.

[0060] In S450, the change distance information is generated based on the absolute value of the difference between the re-checked position information and the relative position information.

[0061] Specifically, the terminal device may first calculate the difference between the re-checked position information and the relative position information, and then calculate the absolute value of the difference to generate the change distance information.

[0062] In S460 , the change distance information is compared with preset change distance threshold information.

[0063] Specifically, the terminal device may compare the distance change information with preset distance change threshold information, wherein the specific value of the distance change threshold information may be customized by the administrator according to actual conditions.

[0064] In S470 , if the change distance information is less than or equal to the change distance threshold information, first generation time information of the relative position information and second generation time information of the rechecked position information are acquired.

[0065] Specifically, if the change distance information is less than or equal to the change distance threshold information, the terminal device can obtain the first generation time information of the relative position information and the second generation time information of the re-inspection position information, wherein the first generation time information is used to describe the generation time of the relative position information, and the second generation time information is used to describe the generation time of the re-inspection position information.

[0066] In S480, the stay time information of the outside object is generated according to the difference between the second generated time information and the first generated time information.

[0067] Specifically, the terminal device can generate the residence time information of the object outside the door based on the difference between the second generated time information and the first generated time information.

[0068] In S500 , the danger level information of the object outside the door is determined according to the relative position information and the residence time information, and an alarm message is generated.

[0069] Specifically, after the terminal device generates relative position information and residence time information, the terminal device can determine the danger level information of the object outside the door based on the relative position information and residence time information, and generate alarm information, wherein the danger level information is used to describe the danger level of the object outside the door.

[0070] In some possible implementations, the danger level information includes light danger information, medium danger information, or high danger information, wherein light danger information is used to describe the danger level of the object outside the door as light danger, medium danger information is used to describe the danger level of the object outside the door as medium danger, and high danger information is used to describe the danger level of the object outside the door as high danger, thereby effectively classifying the danger level of the object outside the door. In order to further classify the danger level of the object outside the door, please refer to Figure 3 Step S500 includes but is not limited to the following steps:

[0071] In S510 , the residence time information is compared with the preset residence time threshold information.

[0072] Specifically, the terminal device may compare the residence time information with preset residence time threshold information, wherein the specific value of the residence time threshold information may be customized by the administrator according to actual conditions.

[0073] In S520 , if the residence time information is greater than or equal to the residence time threshold information, the relative position information is compared with the preset first distance threshold information, and the relative position information is compared with the preset second distance threshold information.

[0074] Specifically, the second distance threshold information is greater than the first distance threshold information. The specific values ​​of the second distance threshold information and the first distance threshold information can be customized by the administrator based on actual conditions. If the dwell time information is greater than or equal to the dwell time threshold information, the terminal device can compare the relative position information with the preset first distance threshold information, and simultaneously compare the relative position information with the preset second distance threshold information.

[0075] In S530 , if the relative position information is greater than or equal to the second distance threshold information, the danger level information is determined to be mild danger information.

[0076] Specifically, if the relative position information is greater than or equal to the second distance threshold information, the terminal device may determine that the danger level information is mild danger information.

[0077] In S540 , if the relative position information is less than the second distance threshold information and the relative position information is greater than the first distance threshold information, it is determined that the danger level information is moderate danger information.

[0078] Specifically, if the relative position information is less than the second distance threshold information and the relative position information is greater than the first distance threshold information, the terminal device can determine that the danger level information is moderate danger information.

[0079] In S550 , if the relative position information is less than or equal to the first distance threshold information, the danger level information is determined to be high danger information.

[0080] Specifically, if the relative position information is less than or equal to the first distance threshold information, the terminal device may determine that the danger level information is highly dangerous information.

[0081] In S560 , alarm information is generated based on the danger level information.

[0082] Specifically, after the terminal device determines the specific danger level information, the terminal device can generate alarm information based on the danger level information, thereby issuing an alarm to the elderly and / or the monitoring center.

[0083] In some possible implementations, in order to achieve timely and automatic alerts and effectively improve security, please refer to Figure 4 Step S560 includes but is not limited to the following steps:

[0084] In S561, if it is determined that the danger level information is mild danger information, alarm information and mild danger identification information are generated.

[0085] Specifically, if the terminal device determines that the danger level information is mild danger information, the terminal device may generate alarm information and mild danger identification information.

[0086] In S562, the alarm information and the mild danger identification information are uploaded to the designated server of the monitoring center.

[0087] Specifically, the terminal device can upload alarm information and mild danger identification information to the designated server of the monitoring center, thereby reducing the frequent worries of the elderly and enabling the monitoring center to be informed of possible dangers in a timely manner.

[0088] In S563, if it is determined that the danger level information is moderate danger information, alarm information and moderate danger identification information are generated.

[0089] Specifically, if the terminal device determines that the danger level information is moderate danger information, the terminal device may generate an alarm message and a moderate danger identification message.

[0090] In S564, the alarm information is uploaded to the designated terminal of the room user.

[0091] Specifically, the terminal device can upload the alarm information to the designated terminal of the room user, where the room user may be an elderly person in an aging-friendly space.

[0092] In S565 , it is determined whether the user confirmation information is received within the specified time period.

[0093] Specifically, if the elderly person determines that the person outside the door is an unregistered person, they can use their designated terminal to send a user confirmation message to the terminal device. If the elderly person determines that the person outside the door is not an authorized person, they do not need to send the user confirmation message to the terminal device. The terminal device can then determine whether the user confirmation message has been received within a specified time period.

[0094] In S566, if the user confirmation information is received within the specified time period, the alarm information is deleted; otherwise, the alarm information and the moderate risk identification information are uploaded to the designated server of the monitoring center.

[0095] Specifically, if a user confirmation message is received within a specified time period, the terminal device can delete the alarm message. Otherwise, the terminal device can upload the alarm message and moderate danger identification information to the designated server of the monitoring center, so that the monitoring center can be informed of possible dangers in a timely manner and avoid misjudgments.

[0096] In S567, if the danger level information is determined to be high-risk information, alarm information and high-risk identification information are generated.

[0097] Specifically, if the terminal device determines that the danger level information is high-danger information, the terminal device may generate alarm information and high-danger identification information.

[0098] In S568, the alarm information and the high-risk identification information are uploaded to the designated terminal of the room user, and the alarm information and the high-risk identification information are uploaded to the designated server of the monitoring center.

[0099] Specifically, the terminal device can first upload the alarm information and high-risk identification information to the designated terminal of the room user, so that the elderly can be informed of possible dangers in a timely manner, and at the same time upload the alarm information and high-risk identification information to the designated server of the monitoring center, so that the monitoring center can be informed of possible dangers in a timely manner.

If the risk identity information is dangerous identity information, the relative position information and residence time information of the object outside the door are obtained, and then the danger level information of the object outside the door is accurately determined based on the relative position information and residence time information, and at the same time generate alarm information to realize automatic alarm when the object outside the door is a possible or confirmed dangerous person, shorten the waiting time for issuing the alarm, and effectively improve safety.
