Description

Technical Field

[0001] The utility model relates to the technical field of perimeter security, in particular to a video composite detection device suitable for perimeter security. Background Art

[0002] Perimeter security systems are based on physical security measures, usually a steel mesh fence that is generally 2 to 3 meters high and has a barbed wire cage on top. Video surveillance cameras are installed on poles on the inside of the perimeter. Due to installation height restrictions in certain scenarios, blind spots are inevitable outside the perimeter. When an intrusion alarm is generated on the perimeter, the video surveillance cannot see the image outside the perimeter.

[0003] Currently, to address this issue, vibration or radar intrusion detectors are typically installed on the fence. These detectors are then supplemented with small, micro-video surveillance cameras, creating a composite detector with video surveillance capabilities. This allows for comprehensive monitoring of the area outside the fence, allowing for video verification of intrusion alarms generated by the vibration or radar. These detectors are deployed in a node array along the perimeter of the fence and utilize wide-angle or ultra-wide-angle lenses, with overlapping fields of view between adjacent cameras. This arrangement significantly reduces the blind spots of traditional perimeter security video surveillance systems. However, in practice, significant blind spots still exist within 1-2 meters of the perimeter, particularly when people or vehicles are moving closely against the fence, preventing the full video image from being captured.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0028] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] In areas close to the fence, such as within a distance of ≤1-2 meters, there are still large blind spots. Especially when people or vehicles are moving close to the fence, it is impossible to obtain their complete video surveillance images. Figure 1 As shown, one is to add a rotating mechanism to the detector or its mounting bracket to adjust the direction of the lens. In actual application, due to the limitation of the steel mesh fence, the rotation angle of the lens is limited, so the overall effect is not good; the second is to add two or more lenses to the composite detector to expand the field of view of the video surveillance, which can solve the problem of blind spots near the fence area. However, the disadvantage of this solution is that it increases the structural complexity and production cost of the composite detector, as well as the networking problem caused by increased power consumption. Based on this, the utility model provides a detection device for fence security, in which a collection component is provided on the outside of the fence through a mounting mechanism, and the lens of the collection component faces the extension direction of the fence. The orthographic projection of the shooting range of the collection component on the horizontal plane includes a first boundary and a second boundary, and the orthographic projection of the fence on the same horizontal plane is located between the first boundary and the second boundary, thereby achieving monitoring without blind spots and the flexible adjustment of the lens direction of the collection component through the mounting mechanism.

[0030] Figure 2 This is a schematic diagram of the structure of a video composite detection device suitable for perimeter security provided by the utility model. Figure 2 As shown, the device includes a composite detector.

[0031] The composite detector includes a collection component 200 and a detector 100. The collection component 200 is connected to the detector 100. The detector 100 is arranged on the inner side of the fence. The collection component 200 is arranged on the outer side of the fence through a mounting mechanism. The mounting mechanism drives the collection component 200 to rotate vertically or horizontally. The lens of the collection component 200 is facing the extension direction of the fence. The orthographic projection of the shooting range of the collection component 200 on the horizontal plane includes a first boundary and a second boundary. The orthographic projection of the fence on the same horizontal plane is located between the first boundary and the second boundary.

[0032] like Figure 3 As shown, the present invention installs the acquisition component 200 on the steel mesh fence and is located on the outside of the fence through a mounting mechanism. The mounting mechanism drives the lens of the acquisition component 200 to rotate, thereby adjusting the horizontal and vertical angles of the lens to adapt to site requirements, such as undulating ground. The lens of the acquisition component 200 is directed toward the extension direction of the fence. The orthographic projection of the shooting range of the acquisition component 200 on the horizontal plane includes a first boundary and a second boundary. The orthographic projection of the fence on the same horizontal plane is located between the first boundary and the second boundary. Image information of people or vehicles moving close to or close to the fence and other targets can be collected to achieve monitoring without blind spots.

[0033] In a possible embodiment, multiple composite detectors are evenly arranged along the extension direction of the fence.

[0034] Since the installation height of the composite detector is about 1.5 meters, there is a certain video blind area below the composite detector. The video blind area can be filled by adjacent composite detectors. For example, the distance between two adjacent composite detectors is 5 to 6 meters.

[0035] In a possible embodiment, the lenses of the multiple acquisition components 200 face the same direction, and the shooting ranges of two adjacent acquisition components 200 partially overlap.

[0036] Specifically, such as Figure 4 As shown, multiple composite detectors are evenly spaced along the extension of the fence. Their imaging ranges face the same direction, and the imaging ranges of two adjacent composite detectors partially overlap. This means that the subsequent composite detector fills in the blind spot of the previous composite detector, eliminating the blind spot of a single composite detector or making the image information it captures clearer.

[0037] Furthermore, the composite detectors may be arranged in an array, distributed or node manner.

[0038] In a possible embodiment, the acquisition component 200 includes at least any one of a video acquisition unit, a vibration acquisition unit, and a radar acquisition unit.

[0039] Specifically, composite detectors include vibration detectors, radar detectors and video composite detectors. The vibration detector mainly detects by sensing the tiny vibrations generated by the target object; the radar detector uses radio waves for detection and ranging, and determines the position and parameters of the target by emitting electromagnetic waves and receiving the reflected signals. It has the characteristics of strong penetration and high positioning accuracy; the video composite detector usually refers to a detector combined with video surveillance technology, which uses a camera to capture the scene and identifies the target through image processing and analysis technology.

[0040] When a radar detector or vibration detector detects a target, the target can be reviewed and confirmed through video footage, improving the accuracy and reliability of detection. It is also highly intuitive and can display the on-site situation in real time, providing decision makers with intuitive and comprehensive information.

[0041] In a possible embodiment, the video acquisition unit is a wide-angle camera.

[0042] In a possible embodiment, the mounting mechanism includes a first rotating assembly and a second rotating assembly, the first rotating assembly is connected to the second rotating assembly, and the second rotating assembly is fixedly connected to the outer side of the fence.

[0043] In a possible embodiment, the distance between the collection component 200 and the outside of the fence is less than 10 centimeters.

[0044] Specifically, the first rotating assembly drives the collection assembly 200 to rotate along a first rotating axis (i.e., horizontally) to adjust the pitch angle of the collection assembly 200 so that the collection assembly 200 avoids blind spots in its shooting range, wherein the axis of the first rotating axis is an axis perpendicular to the height direction of the fence;

[0045] The second rotating assembly drives the collection assembly 200 to rotate along the second rotating axis (ie, vertical direction) to adjust the positional relationship between the shooting range of the collection assembly 200 and the fence, that is, to adjust the shooting range inside or outside the fence.

[0046] Furthermore, the first rotating assembly and the second rotating assembly can adjust the collection assembly 200 to an adjustable range of 180 degrees.

[0047] In a possible embodiment, the detector 100 includes an identification unit and an early warning unit. The identification unit is connected to the acquisition component 200, and the early warning unit is connected to the identification unit. The identification unit is used to analyze the captured images collected by the acquisition component 200 to obtain analysis results, and the early warning unit generates an early warning signal based on the analysis results.

[0048] In a possible embodiment, the detector 100 further includes a storage unit, which is connected to the recognition unit and the warning unit respectively, and is used to store captured images, analysis results, and warning signals.

[0049] Specifically, the detector 100 acquires the captured image of the acquisition component 200, analyzes the captured image through the recognition unit, and sends the analysis result to the early warning unit, which issues an early warning based on the analysis result.

[0050] The recognition unit uses AI analysis to classify and identify targets and their actions in the captured images. The recognition unit can automatically extract features and classify image data based on computer vision, machine learning, and deep learning technologies. By training these models, it can learn and identify target objects and their actions from a large number of images.

[0051] In this application, the recognition unit uses the neural network CNN algorithm in the edge computing mode to process the captured image. The specific process is as follows:

[0052] First, the captured image data is preprocessed on the edge device, including data cleaning, data conversion, data enhancement, and other operations to facilitate subsequent neural network processing;

[0053] Secondly, the pre-processed captured image data is input into the CNN model and the prediction results are output;

[0054] Then, the prediction results are cached on the edge device to improve the system's response speed;

[0055] Finally, the CNN model is optimized. Through real-time feedback from edge devices, the CNN model can be optimized to improve the accuracy of the model.

[0056] In a possible embodiment, the detector further includes a power supply unit and a networking unit. The power supply unit is connected to the acquisition component to provide power to the acquisition component. The networking unit is connected to the acquisition component to send image information captured by the acquisition component to the recognition unit of the detector.

[0057] The utility model of the present application is mainly aimed at the fence security scene, and adopts array-type, distributed or node-type video composite detectors to monitor the outside of the fence in real time, and by pointing the video lens towards the extension direction of the fence, it can achieve blind-spot monitoring, reduce costs, and avoid the situation where the terminal equipment cannot work stably due to the increase in network power consumption and voltage drop caused by the installation of too many composite detectors; the acquisition component is fixed on the fence through the installation mechanism, so that the angle of the lens of the acquisition component in the vertical and / or horizontal direction is adjusted to make its shooting range more suitable for the scene; by setting multiple composite detectors, and the shooting ranges of adjacent composite detectors partially overlap, the video blind spot of a single detector is eliminated, and the video image collected by it is clearer and more complete.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
