This technology is widely used in: campus area wall boundary management, company area infrastructure management, residential community security management, hospital designated area management, etc.

[0003] Traditional regional wall boundary management mostly adopts physical prevention and control methods, such as increasing the wall height, installing wire mesh and broken glass on the wall, etc. The construction cost is high, the aesthetics is poor, and there is no relevant feedback and management for intrusion behavior.

The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0039] refer to Figure 1 A monitoring method according to a preferred embodiment of the present invention will be described in detail below, wherein the monitoring method can be used to automatically manage wall-like boundary areas, thereby reducing management costs and delays of existing management methods.

[0040] Specifically, the monitoring method comprises the following steps:

[0041] S1001, collecting monitoring data formed within a predetermined range of the wall, and judging whether there is a moving object on the top of the wall according to constraint conditions.

[0042] Specifically, in step S1001, monitoring data formed within a predetermined range of the wall can be collected by radar, preferably a millimeter wave radar, to determine whether there is a moving object on the top of the wall. It can be understood that the radar can obtain monitoring data of objects in a farther area than the image acquisition device. In this way, if full-range monitoring is to be achieved in an area of ​​the same size, the number of existing image acquisition devices installed can be effectively reduced, thereby reducing costs.

[0043] Specifically, the step S1001 includes the steps of: taking the installation axis of the radar as the common physical system point, establishing the relationship between the spherical coordinate system of the radar wave and the Cartesian coordinate system of the wall, and:

[0044] 80°≤θ≤90°;

[0045] z≤H, is the constraint condition, monitoring whether there is a moving object on the top of the wall, where

[0046] θ is the angle between the projection of the line connecting the active object and the coordinate circle point in the radar spherical coordinate system on the XY plane in the XYZ coordinate system and the X axis;

[0047] Where z is the height of the monitored object on the Z axis in the XYZ coordinate system;

[0048] Wherein H is the height of the wall on the Z axis in the XYZ coordinate system;

[0049] In addition, the coordinates of the active object detected by the radar in the XYZ coordinate system are:

[0050] Where r is the distance between the point of the spherical coordinate system where the radar is located and the active object, It is the angle between the moving object and the line connecting the coordinate points in the radar spherical coordinate system in the positive direction of the Z axis.

[0051] In this way, it is possible to effectively prevent people walking near the wall from being misjudged as wall climbers, thereby effectively preventing misjudgment.

[0052] S1002, when a moving object is detected on the top of the wall, the infrared characteristics of the detected moving object are collected, and it is determined whether there is a moving person on the top of the wall; when it is detected that there is no moving object on the top of the wall, continue with step S1001.

[0053] Preferably, in step S1002, when a moving object is detected on the top of the wall, an infrared monitoring device disposed above the top of the wall can be driven to rotate toward the moving object, and the infrared characteristics of the moving object can be collected by the infrared monitoring device to determine whether there is a moving person on the top of the wall.

[0054] S1003, when it is determined that the moving object is not a moving person, continue with step S1001; and when it is determined whether there is a moving person on the top of the wall, collect the image of the moving object obtained through collection.

[0055] S1004: output the image of the moving object.

[0056] Those skilled in the art will appreciate that the image of the moving object may be captured by a camera.

[0057] refer to Figure 2 and Figure 3 For example, take radar (24GHz, ranging range 60 meters, sensitive ranging angle ±60°), wall 800 height 5m as an example. Since the radar monitoring range is a radiation range, it is easy to cause misjudgment due to the presence of moving people under the wall. However, it can be achieved by:

[0058] θ = 90°;

[0059] z≤H is the constraint condition, monitoring whether there is a moving object on the top of the wall 800, that is:

[0060] x=0, that is, cosθ=0, that is, θ=90°

[0061] z≤5, that is Right now

[0062] It is understandable that when the millimeter-wave radar is close (within 20m) and there are pedestrians passing under the wall, the feedback signal corresponding to θ is not 90°, so The feedback signal coordinates do not satisfy the "constraint conditions", and in this case, continue with step S1001.

[0063] When the millimeter-wave radar is far away (more than 20 meters away) and a pedestrian passes under the wall, the feedback signal corresponds to an angle of θ close to 90°, and the difference between its signal coordinates and the feedback coordinates when the intruder climbs over the wall is very small. The millimeter-wave radar cannot make judgments based on angles, and there may be certain false alarms. At this time, it is necessary to use infrared monitoring devices such as infrared imagers to monitor whether there are moving people within 800 meters above the wall to further determine pedestrians and intruders. As follows Figure 3 In the above figure, the difference between point A and point B is not obvious due to the angle θ, which may cause false alarm due to signal coordinate confusion. The height of point B needs to be distinguished through infrared imaging re-inspection procedure.

[0064] The usual operation process is to set 80°≤θ≤90° according to the actual distance, and when θ is greater than the calibration value (80°), execute step S1002.

[0065] refer to Figure 4 According to another aspect of the present invention, the present invention also provides a monitoring system, wherein the monitoring system includes an acquisition module 100, an analysis module 200 and an output module 300, wherein the acquisition module is configured to collect monitoring data formed within a predetermined range of the wall, and when a moving object is detected on the top of the wall, the infrared characteristics of the moving object are collected.

[0066] The analysis module is communicatively connected to the acquisition module, wherein the acquisition module determines whether there is a moving object on the top of the wall based on constraint conditions; and determines whether there is a moving person on the top of the wall based on the infrared characteristics of the moving object; and when there is a moving person on the top of the wall, the image of the moving object is acquired.

[0067] The output module is communicatively connected to the analysis module, wherein the output module is configured to output an image of the moving object.

[0073] When the moving object is a moving person, capturing an image of the moving object acquired through capturing; and

[0074] An image of the moving object is output.
