Description
Technical Field
The disclosure relates to the technical field of security protection, in particular to a method and a device for starting a defense deploying function.
Background
Along with the development of society, the demand of people for public security is higher and higher. In some monitoring places (such as banks, jewelry stores and the like), no person on duty is left in the monitoring places for watching after the time on duty. For example, after 5 pm, all personnel in the bank are off duty, including on-site security personnel. At this time, delayed defense deployment is required for the monitored site.
The delayed arming is to start the arming function after a preset time. For example, a bank-related person operates and starts the delayed defense function in a computer device, the computer device counts down, and after 30 seconds, the defense function is automatically started. After the defense deploying function is started, security check equipment such as infrared equipment near the entrance guard emits infrared rays, and the projection of the infrared ray beams on the ground can be called an alarm detection line. When a person crosses the alarm detection line, the infrared ray can be shielded, so that the infrared equipment can detect the entrance of the person, and further can perform alarm processing. In the process, the reason for delay defense deployment is that a certain delay is left for relevant personnel to go out of a monitoring place after operating computer equipment, so that false alarm caused by the fact that the security inspection equipment detects the relevant personnel is avoided.
In carrying out the present disclosure, the inventors found that at least the following problems exist:
the time delay duration in the time delay defense deployment is difficult to set. If the setting is short, related personnel do not leave the monitoring place, the defense deploying function is started, and further false alarm is generated because the security inspection equipment detects the related personnel. If the setting is long, the related personnel have already walked out of the monitoring place for a period of time, and the defense function has not been started, and the time gap can be utilized by lawbreakers. There is no effective mechanism to solve the above problems.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the disclosure provides a method for starting a defense deploying function, which can be realized by a terminal. The terminal can be a tablet computer, a desktop computer, a defense terminal and the like.
The terminal may include a processor, memory, etc. The processor, which may be a CPU (Central Processing Unit), may be used for analyzing the image, obtaining an analysis result, and the like. The Memory may be a RAM (Random Access Memory), a Flash (Flash Memory), and the like, and may be configured to store received data, data required by the processing procedure, data generated in the processing procedure, and the like, such as a preset distance threshold.
The terminal may also include a transceiver, input components, display components, audio output components, and the like. The transceiver can be used for data transmission with the server and sending alarm information to the server, and the transceiver can comprise a Bluetooth component, a WiFi (Wireless-Fidelity) component, an antenna, a matching circuit, a modem and the like. The input means may be a touch screen, keyboard, mouse, etc. The audio output component may be a speaker, headphones, or the like.
An exemplary embodiment of the present disclosure provides a method for starting a defense function, as shown in fig. 1, a processing flow of the method may include the following steps:
step S110, receiving an instruction to start the arming function.
In implementation, after the duty time of the monitoring place is over, a related person can be left to trigger the starting of the defense function of the monitoring place. As shown in fig. 2, a terminal for triggering the opening of the arming function of the monitoring place may be disposed at a position a, a door is at a position B, and after the terminal triggers the opening of the arming function of the monitoring place, a relevant person needs to travel a distance to reach the position B where the door is located, and then exit from the door to the outside of the monitoring place. In the process that the relevant person reaches the position B where the door is located through a certain distance, the person needs to pass through a box-selected area, and the area is the defense area. If the defense function is immediately effective after the related personnel trigger the start of the defense function of the monitoring place, the related personnel can be detected by the security inspection equipment when passing through the defense area, and false alarm is generated. Therefore, it is necessary to wait for the relevant person to leave the defense area and then to enable the defense function.
When related personnel carry out triggering operation for starting the defense deploying function in the terminal, the terminal can receive an instruction for starting the defense deploying function.
And step S120, acquiring the image shot by the monitoring equipment, and analyzing the image to obtain an analysis result.
In implementation, the images captured by the monitoring device may be analyzed, such as a recognition process, a process of determining the position of a target person, and the like. After the images taken by the monitoring device are analyzed, corresponding analysis results can be obtained.
And step S130, when the analysis result meets the preset condition of starting the defense function, starting the defense function.
In implementation, when the analysis result meets a preset condition for starting the defense function, the defense function can be triggered to be started.
Alternatively, step S120 may include: the method includes the steps of obtaining an image shot through a monitoring device, and detecting the distance between the position of a target person and a preset reference line in the image. Step S130 may include: and when the detected distance meets the preset condition of starting the defense deploying function, starting the defense deploying function.
In implementation, whether to turn on the arming function may be determined based on the distance between the position of the target person and a preset reference line of the image.
Optionally, when the detected distance satisfies a preset condition for starting the arming function, the step of starting the arming function may include: and if the detected distance is greater than a preset distance threshold value, starting the defense deploying function. The preset distance threshold is determined based on the distance between the reference line and the corresponding line segment of the preset alarm detection line in the image, and the reference line is the edge line of the corresponding actual line in the image between the alarm detection line and the monitoring equipment.
After the defense deploying function is started, security check equipment such as infrared equipment near the entrance guard emits infrared rays, and the projection of the infrared ray beams on the ground can be called an alarm detection line. When a person crosses the alarm detection line, the infrared ray can be shielded, so that the infrared equipment can detect the entrance of the person, and further can perform alarm processing. Or, the monitoring device shoots an image in a monitoring place, and when the image includes a person image, alarm processing is performed, and corresponding actual lines closest to the entrance guard among four edges in an effective shooting area of the monitoring device may be called alarm detection lines.
Further, the reference line may be an edge line in the image where the corresponding actual line is located between the alarm detection line and the monitoring device. If four edge lines of the image are mapped into reality, there are four real lines. An actual line corresponding to the edge line is arranged between the alarm detection line and the monitoring equipment, and the edge line can be selected as a reference. The reference line may also be a line set by a user, and the user may input the position of the reference line in the image in the terminal, for example, the position of the reference line in the image by a slide selection operation, or the coordinates of the horizontal axis, the vertical axis, and the like of the reference line in the image. The terminal can acquire the position of the input reference line in the image, but requires that the actual line corresponding to the input reference line is positioned between the alarm detection line and the monitoring equipment.
In practice, as shown in fig. 2, a monitoring device may be located at location C, and the monitoring device may capture images of a scene over a large area within the monitored facility, such as an area of a defense. The monitoring device can shoot images in the monitoring place according to a preset period and send the shot images to the terminal. Further, the terminal can acquire images in the monitoring place. Then, the terminal may identify a target person in the acquired image, determine the position of the target person, and further may determine a distance between the position of the target person and a preset reference line.
The general certain position of fixed mounting of supervisory equipment on the wall that can then have installer adjustment supervisory equipment's shooting angle, can generally adjust supervisory equipment's shooting angle for can clapping the angle in the monitoring place most regional, still can adjust supervisory equipment's shooting focus to can clap the focus in the monitoring place most regional simultaneously, just can not change these shooting parameters again basically after this. Since the shooting parameters are fixed, the distance between the reference line and the alarm detection line in the image is constant and is set as a distance threshold. When the distance between the position of the target person and the preset reference line is larger than the distance threshold, it can be determined that the target person leaves the arming area, and the arming function can be started at this time. In this way, when a person steps into the defense area again, the security inspection equipment can detect and perform alarm processing.
Optionally, the preset distance threshold may be a distance between the reference line and a corresponding line segment of the preset alarm detection line in the image, or a sum of the distance between the reference line and the corresponding line segment of the preset alarm detection line in the image and a preset distance value.
The reference line may be an edge line in the image where the corresponding actual line is located between the alarm detection line and the monitoring device. If four edge lines of the image are mapped into reality, there are four real lines. An actual line corresponding to the edge line is arranged between the alarm detection line and the monitoring equipment, and the edge line can be selected as a reference.
If the distance threshold is set to be the sum of the distance between the reference line and the corresponding line segment of the preset alarm detection line in the image and the preset distance value, a margin can be reserved, and the defense deploying function is started after the target person completely leaves the defense deploying area to prevent false alarm.
In the process of identifying the target person, the target person in the image can be identified through a preset image identification algorithm. The target person in the images can also be identified by detecting moving objects in the two images. As for the second manner, the position of the target person in the moving state in the temporally subsequent image among the at least two images may be determined based on the at least two images acquired by the monitoring apparatus and a preset optical flow algorithm.
The optical flow algorithm may include an algorithm corresponding to a calcptical flowpyrlk, calcptical flowfarneback, calcptical flowbm, calcptical flowhs, calcptical flowsf, and other functions provided in OpenCV (Open Source Computer Vision Library).
The moving object in the image may be determined by an optical flow algorithm, and if the moving object is a human figure, the position of the center of the hindbrain, the position of the center of the body, or the position of the lower boundary of the human figure in the image, that is, the position of the foot, may be selected as the position of the human figure in the image, which is not limited in the embodiment of the present disclosure. Finally, the distance between the position of the person and the preset reference line may be determined based on the position of the person in the image. Therefore, the distance between the position of the person and the preset reference line can be determined in the image with the later shooting time, and the person can be further determined to be in or not to leave the defense area.
Alternatively, step S120 may include: acquiring an image shot by monitoring equipment, and identifying the number of people in the image; step S130 may include: and when the number of the people in the image is larger than a preset number threshold, starting the defense deploying function.
In the embodiment of the present disclosure, two ways are provided to determine the number of people in the image, and certainly, there may be other ways to determine the number of people in the image, which are not described herein again. And when the number of the people in the image is larger than a preset number threshold, starting the defense deploying function.
First, the images of the persons included in the images may be recognized, for example, by a machine learning model trained in advance. And the number of recognized persons can be determined.
Secondly, the target people in the motion state in the image can be determined based on an optical flow algorithm, the number of the target people in the motion state can be further determined, if the number is larger than a preset number threshold value, the defense deploying function is started, and meanwhile, the alarm processing can be carried out.
In implementation, when the number of the target persons in the motion state is determined to be larger than a preset number threshold value, such as 1, alarm processing is performed. If the monitoring place stipulates that only one person is left to trigger the defense-opening function finally, the number threshold value is set to be 1. The number threshold may be set according to specific situations, and may be set by a user. The user can input the quantity threshold value in the terminal, the terminal can generate a defense opening instruction when detecting that the user performs quantity threshold value input operation, and the defense opening instruction can carry the quantity threshold value.
Optionally, when the detected distance satisfies a preset condition for starting the arming function, the step of starting the arming function may include: and if the distance between the position of the target person detected in the image acquired in any shooting period and the reference line is smaller than the distance between the position of the target person detected in the image acquired in a first preset number of shooting periods before any shooting period and the reference line, starting the defense function.
The reference line may be an edge line in the image where the corresponding actual line is located between the alarm detection line and the monitoring device. If four edge lines of the image are mapped into reality, there are four real lines. An actual line corresponding to the edge line is arranged between the alarm detection line and the monitoring equipment, and the edge line can be selected as a reference.
In implementation, if the distance between the position of the target person detected in the image acquired in any shooting cycle and the reference line is smaller than the distance between the position of the target person detected in the image acquired in the first preset number of shooting cycles before any shooting cycle and the reference line, the target person can be determined to go out of the monitoring place in the direction of entrance guard, but returns to the inside of the monitoring place in the opposite direction of the entrance guard on the way, which is illegal, so that the defense function can be immediately started, and meanwhile, the alarm processing can be carried out. The first preset number may be set by a user, the user may input the first preset number in the terminal, and the terminal may acquire and store the input first preset number. The terminal may also obtain a default first preset number, such as 20.
The alarm processing can be prompting security personnel in a security center which governs the monitoring places, turning on the monitoring videos of the monitoring places corresponding to the alarm processing, and remotely checking. If the target person returns to the inside of the monitoring place, the situation that the user forgets to take the object is solved, and the next step of processing can be omitted. If the target person returns to the inside of the monitoring place to take things belonging to the monitoring place or to perform other illegal operations, corresponding processing is needed.
Optionally, when the detected distance satisfies a preset condition for starting the arming function, the step of starting the arming function may include: and if the distance between the position of the target person detected in the image acquired in any shooting period and the reference line is equal to the distance between the position of the target person detected in the image acquired in a second preset number of shooting periods before any shooting period and the reference line, starting the defense function.
The reference line may be an edge line in the image where the corresponding actual line is located between the alarm detection line and the monitoring device. If four edge lines of the image are mapped into reality, there are four real lines. An actual line corresponding to the edge line is arranged between the alarm detection line and the monitoring equipment, and the edge line can be selected as a reference.
In implementation, if the distance between the position of the target person detected in the image acquired in any shooting period and the reference line is equal to the distance between the position of the target person detected in the image acquired in a second preset number of shooting periods before any shooting period and the reference line, the target person can be determined to stay at a certain position in the monitoring place for a period of time, which is illegal, the defense function can be immediately started, and meanwhile, the alarm processing can be carried out. The process of alarm handling is similar to the above-described situation and is not described herein again. The second preset number may be set by a user, the user may input the second preset number in the terminal, and the terminal may obtain and store the input second preset number. The terminal may also obtain a default second preset number, such as 100.
By the method provided by the embodiment of the disclosure, the image shot by the monitoring equipment is analyzed to determine whether to start the defense deploying function, so that the defense deploying function can be prevented from being started by setting a fixed delay time to count down. The method provided by the embodiment can not start the defense deploying function when the related personnel have not left the monitoring place, and can not start the defense deploying function when the related personnel have left the monitoring place for a period of time, so that the time for starting the defense deploying function is more in line with the actual requirement.
