Description

Technical Field

[0001] The present invention relates to the field of intelligent security technology, and in particular to an intelligent security command system and a security command method based on three-dimensional model analysis. Background Art

[0002] While technological advancements bring immense convenience to people, they also create numerous unsafe conditions in certain areas and regions. Security, a constant pursuit, is particularly crucial in specific settings, such as detention centers, the military, and key government agencies. Due to their unique and private nature, security is paramount. Therefore, strict security deployment and effective oversight are essential for these special environments.

[0003] Currently, the security command systems on the market are primarily based on two-dimensional platforms, which monitor and control areas within their jurisdiction to protect their safety. When an emergency occurs, the two-dimensional platform cannot provide immediate information about the actual scene at the incident point, hindering timely response by management personnel. Existing video surveillance systems simply monitor the jurisdiction and are unable to promptly notify management personnel when an emergency occurs within the jurisdiction, hindering their ability to promptly address the incident. Furthermore, existing video surveillance systems cannot locate the location of an emergency. Therefore, when an emergency occurs, management personnel cannot immediately obtain the actual scene information at the incident point, hindering on-site monitoring and response.

[0004] Therefore, a new security command system is urgently needed to solve the defects of the existing technology. Summary of the Invention

In the description of the present invention, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0056] Example 1

[0057] like Figure 1 As shown, a smart security command system based on three-dimensional model analysis includes:

[0058] Data acquisition unit 1 is used to collect and output image information of the jurisdiction from multiple angles. In actual applications, this data acquisition unit 1 can be a high-definition camera and / or aerial photography equipment. This data acquisition unit 1 is primarily used to collect image information of the jurisdiction from multiple angles so that the system can promptly update the three-dimensional model of the jurisdiction based on the collected image information.

[0059] The three-dimensional engine 2 is used to receive the image information fed back by the data acquisition unit 1 and use the image information to establish a three-dimensional model of the jurisdiction; the three-dimensional engine 2 is an important part of the entire intelligent security command system, used to generate a three-dimensional model of the system, and also provides various parameter interfaces and internal support for complex applications, including but not limited to scene rendering, sound playback, behavior control, etc.

[0060] The monitoring and protection system 3 is used to monitor the jurisdiction and issue monitoring anomaly information when security anomalies occur in the jurisdiction. The monitoring anomaly information includes an image of the area where the anomaly occurs. The monitoring and protection system 3 serves as the system monitoring end and is used to obtain various security information of the jurisdiction. The monitoring and protection system 3 may include various cameras for video surveillance.

[0061] Control center 4 receives images of the abnormal area, compares and analyzes them with the established three-dimensional model of the jurisdiction, locates the actual location of the abnormal area within the three-dimensional model, and triggers a flashing alarm at the located location. As the core component of the entire system, control center 4 is electrically connected to data acquisition unit 1, three-dimensional engine 2, and monitoring and protection system 3, and can monitor the operation of three-dimensional engine 2 or monitoring and protection system 3.

[0062] The above-mentioned intelligent security command system based on three-dimensional model analysis collects image information of the jurisdiction through the data acquisition unit 1, and the three-dimensional engine 2 receives the information sent by the data acquisition unit 1 and uses the image information to establish a three-dimensional model of the jurisdiction. The control center 4 of the command system is electrically connected to the monitoring and protection system 3. When a security anomaly occurs in the jurisdiction, it receives the monitoring anomaly information sent by the monitoring and protection system 3, and locates the actual position of the abnormal area in the three-dimensional model of the jurisdiction based on the monitoring anomaly information, and flashes a warning. The management and control personnel are promptly informed of the security anomaly in the jurisdiction through the warning signal, and when they know the security anomaly, they can understand the details of the area where the anomaly occurs through the three-dimensional model, and can take corresponding measures to deal with it in time, so that they can timely control the security situation in the jurisdiction and improve the safety of the jurisdiction.

[0063] More specifically, the operation process of the system is as follows: First, the control center 4 controls the operation of the data acquisition unit 1 so that the data acquisition unit 1 collects image information of the jurisdiction. It should be noted that in the process of collecting image information, the data acquisition unit 1 collects image information of the jurisdiction at a set time interval; and in the process of collecting images, the data acquisition unit 1 collects images of the same area of ​​the jurisdiction multiple times at a set moving distance. For example, if the set time interval is 15 minutes, the data acquisition unit 1 will run once every 15 minutes, collect images in the jurisdiction, and feed back the collected image information to the three-dimensional engine 2. The three-dimensional engine 2 also updates the three-dimensional model of the system once a minute. This ensures that when locating security anomalies, the three-dimensional model located by the control center 4 is updated and can reflect the actual situation of the jurisdiction.

[0064] In actual applications, due to the large area of ​​the jurisdiction and the diverse terrain and buildings involved, the data acquisition unit 1 should not be a single camera, but rather a matrix-type image acquisition device composed of multiple cameras. In the initial application of the intelligent security command system claimed in this application, aerial photography equipment should be used to capture the entire jurisdiction from multiple angles and in all directions, so as to initially establish a comprehensive three-dimensional model of the jurisdiction based on the aerial images. High-definition cameras can then be used to capture information such as buildings and rivers, and the comprehensive three-dimensional model can be updated and supplemented to make the resulting three-dimensional model more consistent with the actual jurisdiction and facilitate the control center 4 in locating security anomalies.

[0065] Furthermore, the data acquisition unit 1 selects different angles and viewpoints based on the intersection of longitude and latitude to perform multiple image acquisitions. When acquiring images from the same angle and viewpoint, the data acquisition unit 1 moves at a set distance to perform multiple image acquisitions. To enable the data acquisition unit 1 to select different angles and times for multiple image acquisitions, the image acquisition unit 1 can be mounted on a guide rail with a slider disposed thereon, which drives the data acquisition unit 1 to move in a single direction or multiple directions to achieve image acquisition. When acquiring images from the same angle and viewpoint, the data acquisition unit 1 does not remain stationary when capturing images of a certain area at a specific angle, but rather moves at a specific speed to capture image information of the same area multiple times at the same angle. For example, when the data acquisition unit 1 captures images at an angle parallel to the north side of a building, the data acquisition unit 1 captures multiple images of the building's north side while moving. This enables the 3D engine 2 to utilize multiple images to improve the accuracy of the established 3D model during image processing.

[0066] More specifically, the use of image information to establish a three-dimensional model of the jurisdiction includes:

[0067] The jurisdiction is divided into regions, and three-dimensional models are built for the divided regions in sequence according to a set order. Since the jurisdiction has a certain area, controlling the three-dimensional engine 2 to perform modeling operations in a set order helps to maintain the stability of the three-dimensional engine 2 operation.

[0068] In practical applications, such as Figure 2 As shown, the three-dimensional modeling operation is performed on the divided areas in sequence according to the set order, including:

[0069] S1. Select the area where the 3D model is to be built and obtain image information of the selected area; the image information obtained includes at least one set of bird's-eye images and 4-8 sets of oblique images; both the bird's-eye images and the oblique images can be obtained using aerial photography equipment. Oblique images can be obtained by shooting from the four directions of the building. For large buildings or complex terrain, eight sets of oblique images should be collected. After collecting oblique images from the four directions of the building at an oblique angle, it is necessary to collect images from the northeast, northwest, southwest, and southeast directions at an oblique angle.

[0070] S2. Convert the acquired image information into three-dimensional point cloud information, and interpolate the converted three-dimensional point cloud information to obtain the corrected point cloud information after interpolation; interpolation of the converted three-dimensional point cloud information is achieved by using multiple image information at the same angle. The clarity of the three-dimensional point cloud information after interpolation needs to be higher than that before interpolation. The principle of interpolation is as follows: there is a certain distance between two adjacent three-dimensional point clouds in the original image, and the three-dimensional point cloud information of multiple image information at the same angle is interpolated between two adjacent three-dimensional point clouds in the original image to fill the gap between the two adjacent three-dimensional point clouds, which is conducive to improving the clarity and accuracy of the established three-dimensional model of the jurisdiction.

[0071] S3. Extracting surface vectors from the corrected point cloud information to obtain a vector model of the area;

[0072] S4. Mapping the vector model of the area using the bird's-eye view image and the oblique image to obtain a three-dimensional model of the area.

[0073] Specifically, the least squares method is used to fit the plane, and the mathematical equation expression parameters of the plane are obtained after fitting the points belonging to the same plane. The plane equation is listed, and finally the vector model of the building is obtained. In this application, the building or a certain terrain is preliminarily smoothed by the triangulation method. With the help of the key points generated during the execution of the super voxel partitioning method in the previous step as the vertices of the triangulation, the triangulation of the surface can be constructed quickly and efficiently; then the building or a certain terrain surface is vector fitted. Among them, the building surface is a plane, and the intersection line between the surfaces is a straight line. The created three-dimensional model is smooth, the effect and quality are relatively good, and it is convenient for subsequent mapping. The intersection lines and surfaces of the model obtained by creating a triangulation network through the traditional point cloud are not smooth, which is inconsistent with the actual situation of the building.

[0074] In this application, after obtaining a vector model of the area for which a 3D model is to be built, the coordinates of the corner points in the vector model are extracted. Simultaneously, the oblique photography data is processed, including aerial triangulation of the oblique photography imagery to obtain aerial triangulation results. Then, corresponding points of the corner points of the regional vector model are found on the processed oblique photography and absolute orientation is performed. Finally, the absolute orientation results of the oblique imagery are texture mapped onto the regional vector model to obtain a 3D model of the area. The 3D models of each area constitute a comprehensive 3D model of the entire jurisdiction.

[0075] In this embodiment, the monitoring and protection system 3 includes a video monitoring system 41, and the video monitoring system 41 is electrically connected to the control center 4;

[0076] The video surveillance system 41 is used to monitor whether there is any intrusion into restricted areas, whether there is any detention of people in key areas, and whether there is any suspicious items left behind;

[0077] When the video surveillance system 41 detects an intrusion into a restricted area within the jurisdiction, it sends a first warning signal to the control center 4 and feeds back an image of the intrusion into the restricted area to the control center 4;

[0078] When the video surveillance system 41 finds that people are stranded in key areas within the jurisdiction, it sends a second warning signal to the control center 4 and feeds back images of the key areas where people are stranded to the control center 4;

[0079] When the video surveillance system 41 detects a suspicious item left behind within its jurisdiction, it sends a third warning signal to the control center 4 and feeds back an image of the area where the suspicious item was left. Monitoring for suspicious items can be accomplished by presetting characteristic images of suspicious items in the control system. When the video surveillance system 41 detects an image similar to the pre-set image during monitoring, it sends a third warning signal to the control center 4.

[0080] The video surveillance system 41 includes multiple cameras within the jurisdiction, which are used to conduct all-round monitoring of the jurisdiction. The principle of the video surveillance system 41 in determining whether there is anyone intruding into the restricted area is to first obtain an image of no one in the restricted area, and then obtain an image of the restricted area in real time, compare and analyze the real-time image with the previously obtained image, determine whether there are similarities and differences, and then determine whether there is an intrusion into the restricted area. When the video surveillance system 41 monitors different anomalies, it sends different warning signals to the control center 4, so that the control center 4 can implement different types of warnings after receiving different warning signals. Therefore, the management and control personnel can promptly understand the type of anomaly that has occurred based on different warnings, which is conducive to the management and control personnel to make response plans in a timely manner to better control emergencies.

[0081] The present invention also provides a security command method, which is implemented using the intelligent security command system based on three-dimensional model analysis as described above;

[0082] like Figure 3 As shown, the security command method includes the following steps:

[0083] S100: Constructing a three-dimensional model of the jurisdiction; wherein the three-dimensional model of the jurisdiction includes the terrain and buildings of the jurisdiction;

[0084] S200, associate the monitoring and protection system 3 of the jurisdiction and receive monitoring anomaly information fed back by the monitoring and protection system 3;

[0085] S300, based on the monitoring abnormality information fed back by the monitoring and protection system 3, the monitoring abnormality is located in the three-dimensional model;

[0086] S400. At the location where the monitoring anomaly is located, a monitoring anomaly alarm is issued to remind the management and control personnel to handle it. In the present application, issuing a monitoring anomaly alarm includes highlighting the location where the monitoring anomaly is located in the three-dimensional model to display the alarm. In another embodiment, the alarm system also includes an alarm wristband, which is worn on the hands of the management and control personnel and is connected to the smart security command system via a network connection or Bluetooth. When a monitoring anomaly occurs, the wristband vibrates or flashes to remind the management and control personnel to handle the monitoring anomaly in a timely manner. It should be noted that the reminder of the wristband will be different according to different warning signals. For example, when the control center 4 receives the first warning signal, the wristband vibrates at a lower frequency for 3 seconds; when the control center 4 receives the second warning signal, the wristband vibrates at a lower frequency for 3 seconds and flashes...

[0087] This security command method can quickly locate emergencies in the jurisdiction and enable control personnel to know and understand the specific situation on the scene in a timely manner so that control personnel can take corresponding measures to deal with the emergencies in a timely manner.

[0088] Example 2

[0089] This embodiment only describes the differences from Embodiment 1, and the remaining technical features are the same as those of the above embodiment.

[0090] In an embodiment, the monitoring and protection system 3 includes a perimeter intrusion alarm system 42, which is used to determine whether there is an illegal intrusion in the jurisdiction, and when an illegal intrusion occurs in the jurisdiction, it sends a fourth warning signal to the control center 4 and feeds back an image of the area where the illegal intrusion occurs to the control center 4.

[0091] The principle of perimeter intrusion detection is to construct a perimeter for the jurisdiction and preset a perimeter graphic in the control center 4. The perimeter is then compared with the preset perimeter graphic, captured in real time by the monitoring system, to determine whether an illegal intrusion has occurred. It should be noted that in addition to determining the difference between the real-time captured graphic and the preset perimeter graphic, the perimeter intrusion alarm system 42 should also preset the characteristics of authorized personnel to facilitate access to the jurisdiction.

[0092] Example 3

[0093] This embodiment only describes the differences from Embodiment 2, and the remaining technical features are the same as those of the above embodiment.

[0094] In this embodiment, the monitoring and protection system 3 includes an access control monitoring and alarm system 43, which is used to monitor whether there are any abnormalities in the access control system of the jurisdiction. When an abnormality occurs in the access control system of the jurisdiction, the system sends a fifth warning signal to the control center 4 and feeds back an image of the abnormal area of ​​the access control system to the control center 4.

[0095] Among them, access control system abnormalities include: abnormal closing of the protective door, damage to the access control system, and the use of invalid door cards.

[0096] In practical applications, access control system anomalies are often detected using the system's current signal. For example, the current signal from a protective door closing abnormally will differ from the current signal from a normal closing. Swiping an invalid door card can also cause the access control system to display multiple current fluctuations.

[0097] Example 4

[0098] This embodiment only describes the differences from Embodiment 3, and the remaining technical features are the same as those of the above embodiment.

[0099] In this embodiment, the monitoring and protection system 3 includes a fire monitoring system 44, which includes temperature sensors, smoke sensors, and combustible gas sensors installed in the jurisdiction. The fire monitoring system 44 is used to monitor whether there are any fire anomalies in the jurisdiction. When a fire anomaly occurs, it sends a sixth warning signal to the control center 4 and feeds back an image of the abnormal area to the control center 4.

[0100] The fire protection anomalies include temperature sensing anomalies, smoke sensing anomalies, and combustible gas sensing anomalies.

[0101] The temperature sensor, smoke sensor, and combustible gas sensor are typically installed at specific locations within a jurisdiction, allowing for fire monitoring of key areas within the jurisdiction. In practical applications, the specific location coordinates of the sensors can also be preset in the control center 4. This allows the control center 4 to promptly locate the alarm location based on the preset locations when the sensors sound an alarm, allowing management personnel to take immediate action.

[0102] Example 5

[0103] This embodiment only describes the differences from Embodiment 4, and the remaining technical features are the same as those of the above embodiment.

[0104] The monitoring and protection system 3 includes an operation linkage monitoring system 45, which divides the jurisdiction into several operation areas and assigns different safety factors to different operation areas; specifically, it includes:

[0105] Input the location coordinates of the three-dimensional model of the jurisdiction; the process of inputting the location coordinates is that the operator inputs the location coordinates of different points to the control center 4 of the system through the input device;

[0106] The location coordinates of the three-dimensional model of the jurisdiction are used to construct the boundaries of the operating area and establish different operating areas; the control center 4 constructs the boundaries of the operating area based on the input coordinates; in the process of constructing the boundaries, the center positions of different areas can be selected first, and then gradually constructed based on the outward diffusion of the center positions. It should be noted that in actual applications, it is necessary to construct a fuzzy boundary of the operating area. For example, after the boundary of the operating area is constructed, a threshold distance from the operating boundary is set, which can be 5m or 10m. The area within the threshold distance is used as the fuzzy boundary of the operating area. When an operator with a safety factor matching the operator appears in the fuzzy boundary, the monitoring and protection system 3 will not alarm. This design is to reduce false alarms of the monitoring and protection system 3 and reduce resource waste.

[0107] Assign different safety factors to different operating areas according to their different safety levels;

[0108] The operation linkage monitoring system 45 assigns different level coefficients to different personnel, including:

[0109] Obtain information about different operators;

[0110] Different level coefficients are assigned based on different operator information; the safety factor of the operating area and the level coefficient of the operator form a mapping relationship;

[0111] When an operator with a level coefficient that does not correspond to the safety factor of the work area appears in the work area, the operation linkage monitoring system 45 sends a seventh warning signal to the control center 4 and feeds back an image of the work area to the control center 4. In a more preferred embodiment, the control center 4 presets a residence time at the fuzzy boundary of the work area. When an operator with a level coefficient that does not correspond to the safety factor appears within the fuzzy boundary of the work area and the operator's residence time exceeds the preset time, the monitoring and protection system 3 sends a seventh warning signal to the control center 4.

[0112] The operation linkage monitoring system 45 monitors each operation area. If an unauthorized person enters a prohibited area, the corresponding alarm response level is immediately triggered. If a distress signal is received from an on-site personnel, the person is immediately located and highlighted in the three-dimensional scene. By setting up the operation linkage monitoring system 45, the disorderly flow of personnel can be prevented, helping to ensure the safety of key areas.

[0113] The intelligent security command system based on three-dimensional model analysis of this application can send out different alarm signals according to the warning signals of different monitoring systems, so that management and control personnel can respond in time according to different alarm signals, which helps to ensure the safety of the jurisdiction.

[0114] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures. In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0115] For ease of description, spatially relative terms such as "above," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" can include both the "above" and "below" orientations. The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0116] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can be subject to various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
