Description

Technical Field

[0001] The present application relates to the field of security monitoring, and in particular, to a security monitoring method and system. Background Art

[0002] With the rapid development of information technology, high-end residential areas have gradually introduced intelligent security monitoring systems. The security system is short for the security & protection system (SPS), which aims to maintain social public security and uses intrusion alarm systems, video security monitoring systems, access control systems, explosion-proof security inspection systems, etc. composed of security protection products and other related products; or an electronic system or network composed of these systems as subsystems or integrated.

[0003] Common security systems usually set cameras on the public main roads in residential areas, and use these cameras to continuously shoot the detected areas, that is, objects, and perform image processing on the images collected by the cameras, and then identify the passing personnel and open the residential area gate corresponding to the passing personnel. However, in low-light and no-light environments, the amount of image information collected by the cameras is too low, and image recognition is difficult. Often, it is difficult for passing personnel to open the gate through face recognition. Moreover, due to the certain time delay of the closing action after opening the door, it is also easy to let in irrelevant personnel who follow the passing personnel, damaging the overall security situation.

[0004] Therefore, it is very necessary to provide a security monitoring method and system that can accurately perform image recognition to control the residential area portal in low-light or no-light environments and actively alarm irrelevant tracking personnel. Summary of the Invention

[0033] The door closing execution module is used to execute the door closing action according to the door closing information.

[0034] The present application includes at least one of the following beneficial technical effects:

[0035] 1. There are two ways to identify the target identity information. One is the traditional recognition through facial images, which supports piecing together complete target facial image information that meets the requirements through the current facial image information, and then confirming the target identity information through image recognition, which is convenient for residents to operate; the other is to recognize the standard footstep patterns of the target footstep information, and confirm the target identity information through the pre-stored footstep patterns of the residents. It supports dim or dark environments to make up for the lack of scene functionality of image identity recognition.

[0036] 2. After determining the target's identity information, the basic door opening information is automatically adjusted according to the target's footsteps information and the preset door basic information, so as to ensure that the door opening action can be completed when the target arrives at the door for the target to enter, avoiding the target waiting in front of the door.

[0037] 3. After determining the target identity information, automatically confirm the target location information based on the target footsteps information, and continuously update the alert interval corresponding to the target location information, and screen out other footsteps information in the alert interval. The people corresponding to these other footsteps information are suspected tailing personnel. According to the other footsteps information and the preset door basic information, the basic door closing information is continuously adjusted to ensure that the target can pass through the door body and block the people corresponding to other footsteps information, thereby preventing irrelevant people from following the target into the door.

[0038] 4. By comparing the standard footstep information in the standard footstep database, the target identity information of the target footstep information is determined. The standard footstep database sets multiple standard footstep information of the same user in different states as a reference to ensure that the footstep information in various common situations can be identified, thereby improving the accuracy of identity recognition.

[0039] 5. When other footsteps from the same person continue to be in the alert zone of the current target position, the timing starts. When the duration reaches the warning duration, the person is determined to be suspected of being a tailed target person. At this time, an alarm is sent to the user corresponding to the target identity information to remind the target person that he is being followed and to enhance personal awareness of prevention.

[0049] First embodiment:

[0050] The first embodiment of the present invention provides a security monitoring method, which includes: collecting target footstep information of the current target, determining the target identity information corresponding to the target footstep information according to a preset standard footstep rule; locking the target position information according to the target footstep information; when the target identity information and the target position information meet the preset identity passing rules, obtaining basic door opening information according to the target footstep information and the preset door body basic information, the basic door opening information includes the door opening speed and the door opening distance; executing the door opening action according to the basic door opening information; when the target position information indicates passing through the door body, obtaining other footstep information that is in the alert interval with the current target position, obtaining basic door closing information according to the other footstep information and the preset door body basic information, the basic door closing information includes the door closing speed; and executing the door closing action according to the basic door closing information.

[0051] In this embodiment, in a dim or dark environment, the target recognition method based on the footstep pattern is supported to ensure accurate identification of identity information. The target position information is locked by the target footstep information, so as to adjust the basic door opening information and open the door to ensure that the user can open the door just when he arrives at the door body; the basic door closing information is adjusted by other footstep information in the alert zone to ensure that other users in the alert period complete the door closing before arriving at the door body, thereby preventing other people from following the user into the door.

[0052] The following is a detailed description of the implementation details of a security monitoring method of this embodiment. The following content is only for the convenience of understanding the implementation details provided, and is not necessary for the implementation of this solution. The specific process of this embodiment is as follows Figure 1 As shown, the following steps are included:

[0053] Step 101, collecting target footstep information of the current target, and determining the target identity information corresponding to the target footstep information according to a preset standard footstep rule.

[0054] Specifically, for the implementation of step 101, refer to Figure 2 as shown, it includes:

[0055] S1-1, collect the footstep information of the scene.

[0056] The scene is set to a certain scene in a residential area, such as a public corridor in a residential area; it can also be set to a scene that requires strict confidentiality, such as a corridor in an enterprise computer room or a corridor in a bank. In the scene of the residential area (such as a public corridor), a sound collection device, such as a recording device, is set to collect the sound information on this main road. According to the coherence of the sounds, these sound information are aggregated according to time to obtain the sound time series information of each sound subject; then, the sound time series information whose sound subject is of the footstep type is screened out, and these sound time series information are called footstep information. Different sound subjects correspond to different footstep information. For example, the sound time series information of person a is called footstep information A, the sound time series information of person b is called footstep information B, and the sound time series information of person c is called footstep information C.

[0057] S1-2, select a certain footstep information as the target footstep information.

[0058] Select one of the multiple footstep information in step S1-1 as the target footstep information. Correspondingly, the person corresponding to this target footstep information is the target person. For example, if footstep information C is selected from footstep information A, footstep information B, and footstep information C, then the person c corresponding to this footstep information C is the target person.

[0059] S1-3, determine the target identity information corresponding to the target footstep information according to the preset standard footstep pattern.

[0060] In one case, multiple standard footstep patterns corresponding to each user identity information are pre-stored. When implementing step S1-3, find the standard footstep pattern satisfied by the target footstep information, and use the user identity information corresponding to this standard footstep pattern as the target identity information.

[0061] In another case, according to the target footstep information and the standard footstep information in the standard footstep database, determine the target identity information corresponding to the target footstep information. The standard footstep database includes user identity information and corresponding multiple standard footstep information. The user identity information includes legal users allowed to pass through the current door body, and the standard footstep information is the standard footstep information recorded by these legal users in different states. For example, the footstep information when a legal user walks normally, runs, or is tired.

[0062] Through a large amount of data comparison, the target footprint information is compared with all the standard footprint information of each legal user in the standard database. When the similarity reaches a preset value, it is determined that the target identity information corresponding to the target footprint information is the legal user corresponding to the standard footprint information. For example, the target footprint information C is compared with the standard footprint information C1, C2, and C3 of the legal user c in the standard database. When the similarity between the target footprint information C and the standard footprint information C1 reaches the preset value, the legal user c corresponding to the standard footprint information C1 is used as the target identity information.

[0063] In addition, the target identity information can also be obtained through the following method: collect the current face image information of the current target, obtain the target face image information that meets the basic portrait requirements according to the current face image information, and determine the target identity information corresponding to the target face image information according to the preset standard face image information set.

[0064] At a specified position of the door body, an image acquisition device is set up, and the image acquisition device collects the current face image information of the current target; when the current face image information meets the face image requirements, the current face image information is directly used as the target face image information, and the corresponding target identity information is identified through image recognition technology; when the current face image information does not meet the face image requirements, the current face image information is continuously collected, and a face template is called, and the pixel point information in each current face image information is filled into the face template until the face template meets the face image requirements, and the updated face template is used as the target face image information. Among them, when there is already corresponding pixel point information in the face template for the pixel point information, the pixel point information will be averaged. For example, the pixel information p in the pixel point of the face image k1 is filled into the N position of the face model, and the pixel information q in the pixel point of the face image k2 is filled into the N position of the face model. Since there is already pixel information p at the N position at this time, when updating the pixel information at the N position of the face model, the sum of the pixel information p and the pixel information q is directly averaged, and the pixel information at the N position of the updated face model is (p + q) / 2.

[0065] Step 102, lock the target position information according to the target footprint information.

[0066] Specifically, positioning is performed in the sound field reference model according to the target footprint information, and combined with the standard position information of the door body, the target position information is obtained.

[0067] According to the distribution of the sound collection devices for collecting footstep information in the scene in step 101 in the residential area, a sound field reference model in the quiet state is set. Add sounds to each position in the scene and collect the large sound field data. Subsequently, use the large sound field data to train the sound field reference model, and add the trained sound field reference model to this step 102. It is worth mentioning that the data collection of the large sound field data can be obtained by adding specified sounds on-site as described above and collecting (that is, the large sound field data is the on-site collection data obtained in the real scene), or in the virtual scene, by simulating the addition of sounds and obtaining it through the known sound propagation law (that is, the large sound field data is the simulation data obtained in the simulation scene).

[0068] During the execution of this step 102, substitute the target footstep information into the previously trained sound field reference model for positioning, and naturally, the target position information corresponding to the target footstep information can be obtained. For example, the target footstep information C includes the footstep information changing with time, that is, the footstep time series of user c; then the corresponding target position information Gc is actually the position information changing with time, that is, the positioning time series of user c.

[0069] Step 103, when the target identity information and the target position information meet the preset identity passing rules, obtain the basic door opening information according to the target footstep information and the preset basic door body information.

[0070] Specifically, the basic door opening information includes the door opening speed and the door opening distance. Refer to Figure 3 As shown, the implementation of step 103 includes:[[]]END]]

[0071] S3-1, when the target identity information is in the user permission list corresponding to the scene and the distance between the target position information and the door body reaches the preset door opening distance, it is determined that the preset identity passing rules are met.

[0072] This step S3-1 indicates that the target identity information and the target position information meet the preset identity passing rule setting. Verify the legality of the target identity information again through the user permission list corresponding to the scene, and judge whether the current target has the desire to open the door through the distance between the latest position in the target position information and the door body. If the distance between the position information and the door body reaches the preset door opening distance, it is determined that the current target is legal and the target has a certain possibility of needing to open the door.

[0073] S3-2, according to the basic door body information and the target position information, obtain the door opening distance; according to the door opening distance and the target walking speed indicated by the target footstep information, combined with the basic door body information, obtain the basic door opening information.

[0074] The step S3-2 indicates that the basic door opening information is calculated based on the footstep information and the preset door basic information. The door basic information includes the door position information h1. Since the target position information refers to the position change of the target as the change is applied, it is essentially the time sequence of the target position. The target position information here uses the target position at the most recent current moment. Figure 4 As shown, according to the door position information h1 and the target position information h2, the door opening distance H = |h1-h2| is obtained.

[0075] Since the target footstep information is essentially a collection of footstep information that changes over time, the target pace can be estimated based on the target footstep information. For example, the target footstep information is substituted into the neural network model to obtain the target estimated trajectory through training, and the target pace is obtained. For another example, the target pace is estimated based on the standard footstep law corresponding to the target footstep information in step 101. The basic information of the door body includes the basic performance of the door body, such as the door body position information, the door body movement range, the door body transportation speed range, etc. According to the door opening distance H and the target pace v, combined with the basic information of the door body, the basic information of the door opening is obtained. The basic information of the door opening can ensure that the door body has entered the door opening state when the target reaches the door body, and will not affect the target passing through the door body.

[0076] It is worth mentioning that according to the door opening distance H and the target speed v', combined with the basic information of the door body, the basic information of the door closing can be obtained. It can be assumed that the door body is a shutter opening and closing door. At this time, the opening and closing angle corresponding to the door angle is θ, the door body rotation radius is R, and the door body rotation speed is ω. Then it needs to satisfy H+R*sin(θ+ωt)=v't, so as to know the closing speed ω and the opening time t.

[0077] Step 104, executing the door opening action according to the door opening basic information.

[0078] Step 105, when the target position information indicates passing through the door body, obtain other footstep information in the alert interval with the current target position, and obtain basic door closing information based on other footstep information and preset door body basic information, the basic door closing information including the door closing speed.

[0079] Specifically, when the latest position information in the target position information determined in step 102 indicates that the target has passed through the door body, step 105 is executed.

[0080] refer to Figure 5 As shown, with the current target position corresponding to the target person as the center, the preset alert value sets an alert interval with a radius ( Figure 5the framed shaded part), where the preset alert value can be set by the staff with the authority. When this method is running, the method of step 102 is used to identify the landing positions of other footstep information within the same scene, and filter out the footstep information whose landing points are within the alert range (that is, Figure 5 the footstep information corresponding to the person in the middle). When there is only one person within the alert range, the footstep information is set as other footstep information. When there are multiple people within the alert range, further collect the footstep information whose landing positions are within the alert range and classify them according to the sound source to obtain other footstep information corresponding to different sound sources, such as other footstep information D corresponding to person d and other footstep information E corresponding to person e.

[0081] According to the other footstep information and the preset basic information of the door body, obtain the basic information for closing the door. In one case, when there is other footstep information corresponding to only one sound source (person) within the alert range, according to the other position information h3 corresponding to the other footstep information, combined with the door body position information h1 in the basic information of the door body, calculate the closing distance H', H' = |h1 - h3|; obtain the other speed v' according to the other footstep information. Then, according to the closing distance H' and the other speed v', combined with the basic information of the door body, obtain the basic information for closing the door. This basic information for closing the door can ensure that when the person corresponding to the other footstep information reaches the door body, the door body has completed the closing action. Among them, the calculation method of obtaining the other speed v' from the other footstep information is the same as the method of obtaining the target walking speed v from the target footstep information in step 103. In another case, when there is other footstep information corresponding to multiple sound sources (persons) within the alert range, screen out the other footstep information that is closest to the door body and perform the foregoing calculations; according to the other position information h3 corresponding to the screened-out other footstep information, combined with the door body position information h1 in the basic information of the door body, calculate the closing distance H', H' = |h1 - h3|; obtain the other speed v' according to the other footstep information. Then, according to the closing distance H' and the other speed v', combined with the basic information of the door body, obtain the basic information for closing the door.

[0082] It is worth mentioning that according to the closing distance H' and the other speed v', combined with the basic information of the door body, obtaining the basic information for closing the door can be, assuming that the door body is a louver opening and closing door, at this time the opening and closing angle corresponding to the angle of the door is θ, the rotation radius of the door body is R, assuming that the rotation speed of the door body is ω, then it is necessary to satisfy H' + R * sin(θ - ωt) = v't, so as to know the rotation speed ω of closing the door and the closing time t.

[0083] Step 106, perform the closing action according to the basic information for closing the door.

[0084] Step 107: When the duration of other footstep information in the alert range of the current target location reaches the warning duration, an alert is sent to the user corresponding to the target identity information.

[0085] Specifically, based on the determination in Step 105, timing starts when the footstep information corresponding to the same voice subject first enters the alert range, and the timing is cancelled when the footstep information corresponding to the voice subject leaves the alert range. When the duration obtained from this timing reaches the warning duration, that is, when the time for the same voice subject to tail the target person reaches the warning duration, an alert is sent to the user corresponding to the target identity information at this time. This alert can be sending a text message, or playing a voice, or implementing other preset alarm means.

[0086] In one case, considering that the trailing person may be intermittent, the implementation of Step 107 can also be: timing starts when the footstep information corresponding to the same voice subject first enters the alert range, the timing is paused when the footstep information corresponding to the voice subject leaves the alert range, the timing continues when the footstep information corresponding to the voice subject re-enters the alert range within a period of time, and the timing is cancelled when the footstep information corresponding to the voice subject does not appear in the alert range for a longer period of time. When the timing result reaches the warning duration, that is, when the time for the same voice subject to tail (including intermittently tailing) the target person reaches the warning duration, an alert is sent to the user corresponding to the target identity information at this time.

[0087] The step division of the above various methods is only for clear description. When implemented, they can be combined into one step or some steps can be split into multiple steps. As long as they include the same logical relationship, they are within the protection scope of this patent. Making insignificant modifications to the algorithm or process or introducing insignificant designs, but not changing the core design of its algorithm and process, are all within the protection scope of this patent.

One is the traditional method of identifying through face images, which supports piecing together the complete and compliant target face image information from the current face image information, and then realizing the confirmation of the target identity information through image recognition, which is convenient for the householders to operate. The other is to identify the standard step pattern of the target step information and realize the confirmation of the target identity information through the pre-stored step pattern of the householders, which supports in dim or lightless environments to make up for the lack of scene functionality of image identity recognition.

[0103] After determining the target identity information, the basic door-opening information is automatically adjusted according to the target's footstep information and the preset basic door body information, so as to ensure that the target can complete the door-opening action when reaching the door body for entry, and avoid the target waiting in front of the door. Other footstep information representing suspected trailing persons within the alert range is filtered out, and the basic door-closing information is continuously adjusted to ensure that the target can pass through the door body and block the persons corresponding to other footstep information, thereby preventing unrelated persons from trailing the target into the door. When the duration for which other footstep information from the same person continuously remains within the alert range of the current target position reaches the warning duration, it is determined that the person is trailing the target person. At this time, an alarm is sent to the user corresponding to the target identity information to prompt the target person that they are being trailed and improve personal prevention awareness.
