Example 1
As shown in fig. 1, an intelligent security command system based on three-dimensional model analysis includes:
the data acquisition unit 1 is used for acquiring and outputting image information of a district from multiple angles; in practical applications, the data acquisition unit 1 may be a high definition camera and/or an aerial device. The data acquisition unit 1 is mainly used for acquiring image information of a district from multiple angles, so that the system can update a three-dimensional model of the district in time according to the acquired image information.
The three-dimensional engine 2 is used for receiving the image information fed back by the data acquisition unit 1 and establishing a three-dimensional model of the jurisdiction by utilizing the image information; the three-dimensional engine 2 is an important part in the whole intelligent security command system, is used for generating 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 playing, behavior control and the like.
The monitoring protection system 3 is used for monitoring the district and sending monitoring abnormal information when security and protection abnormality occurs in the district, wherein the monitoring abnormal information comprises an image of an abnormal area; the monitoring protection system 3 is used as a system monitoring terminal for acquiring various security information of the district, and the monitoring protection system 3 can comprise various cameras for video monitoring.
And the control center 4 receives the image of the abnormal area, compares the image of the abnormal area with the established three-dimensional model of the jurisdiction, positions the actual position of the abnormal area in the three-dimensional model of the jurisdiction, and enables the positioned position to flash and alarm. The control center 4 is used as a core part of the whole system, is electrically connected with the data acquisition unit 1, the three-dimensional engine 2 and the monitoring protection system 3, and can be connected to the three-dimensional engine 2 or the monitoring protection system 3 for operation.
According to the intelligent security command system based on three-dimensional model analysis, the command system acquires 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 establishes the three-dimensional model of the jurisdiction by using the image information. The control center 4 of the command system is electrically connected with the monitoring protection system 3, receives monitoring abnormal information sent by the monitoring protection system 3 when security protection abnormity occurs in the district, positions the actual position of the abnormal area in the three-dimensional model of the district according to the monitoring abnormal information, and carries out flashing warning. The management and control personnel can know that security protection abnormity occurs in the district in time through the warning signal, can know the detailed condition of the occurrence area through the three-dimensional model when knowing that the security protection is abnormal, and can take corresponding measures to process in time, so that the security protection condition of the district can be controlled in time, and the safety of the district is improved.
More specifically, the system operates as follows: firstly, the control center 4 controls the data acquisition unit 1 to operate, so that the data acquisition unit 1 acquires image information of a district. It should be noted that, in the process of acquiring image information, the data acquisition unit 1 acquires image information of a jurisdiction at a set time interval; and in the image acquisition process, the data acquisition unit 1 acquires images of the same area in the jurisdiction for a plurality of times according to the set moving distance. For example, if the set time interval is 15 minutes, the data acquisition unit 1 runs once every 15 minutes, performs image acquisition in the jurisdiction, and feeds back the acquired image information to the three-dimensional engine 2. The three-dimensional engine 2 also updates the three-dimensional model of the system once in 1 minute. Therefore, when security and protection abnormity positioning is carried out, the three-dimensional model positioned by the control center 4 is updated, and the actual situation of the district can be reflected.
In practical applications, because the area of the district is large and the involved terrain or buildings are various, the data acquisition unit 1 is not only a single shooting device, but also a matrix type image acquisition device composed of multiple shooting devices. When the intelligent security command system claimed by the application is applied for the first time, the aerial equipment is firstly adopted to carry out multi-shot in all directions and at multiple angles on the whole face of the district, so that a whole-face three-dimensional model of the district is preliminarily established according to aerial images. And then, the high-definition camera can be used for collecting information of buildings, rivers and the like, and the full-face three-dimensional model is updated and supplemented, so that the obtained three-dimensional model of the jurisdiction is more in line with the actual situation of the jurisdiction, and the control center 4 is also favorable for carrying out security abnormal positioning.
Further, the data acquisition unit 1 selects different angle viewpoints to perform image acquisition for multiple times according to the cross coordinates of longitude and latitude; and when the images are collected at the same angle viewpoint, the data collection unit 1 moves according to the set distance to collect the images for a plurality of times. In order to realize that the data acquisition unit 1 can select different angle times to acquire images for multiple times, the image acquisition unit can be arranged on the guide rail, a sliding block is arranged on the guide rail, and the sliding block drives the data acquisition unit 1 to move along a single direction or multiple directions so as to acquire the images. When the images are collected from the same angle viewpoint, it means that when the image is collected from a certain area at a certain angle, the data collecting unit 1 is not always moving but moves at a certain speed so that the image information of the certain area at the same angle can be collected many times. For example, when the data acquisition unit 1 acquires an image at an angle parallel to the north of a certain building, the data acquisition unit 1 acquires a plurality of pieces of image information of the north of the building in a moving manner, which enables the three-dimensional engine 2 to improve the accuracy of the created three-dimensional model using the plurality of pieces of image information when performing image processing.
More specifically, the establishing of the prefecture three-dimensional model by using the image information includes:
performing region division on the jurisdictions, and sequentially performing three-dimensional model building operation on the divided regions according to a set sequence; because the district has certain area, control three-dimensional engine 2 and carry out the modeling operation according to the order of setting, help to keep the stability of three-dimensional engine 2 operation.
In practical applications, as shown in fig. 2, the sequentially performing three-dimensional modeling operations on the divided regions in the set order includes:
s1, selecting a region of a three-dimensional model to be established, and acquiring image information of the selected region; wherein the acquired image information comprises at least 1 group of aerial view images and 4-8 groups of inclined images; both the aerial view image and the oblique image can be acquired by using an aerial photographing device. The oblique images can be shot from four directions of the south, the east and the north of the building, and for large buildings or terrains with complex structures, 8 groups of oblique images should be collected. If the oblique images of the buildings in the four directions of the south, the east and the north are acquired at oblique angles, the images are acquired from the four directions of the north, the west, the south, the east and the south at oblique angles.
S2, converting the acquired image information into three-dimensional point cloud information, and interpolating the converted three-dimensional point cloud information to obtain interpolated corrected point cloud information; the interpolation of the converted three-dimensional point cloud information is realized by using a plurality of pieces of image information under the same angle. The definition of the three-dimensional point cloud information after interpolation needs to be higher than that before interpolation. The interpolation principle is as follows: the method has the advantages that a certain distance is reserved between two adjacent three-dimensional point clouds in the original image, the three-dimensional point cloud information of the image information under the same angle is interpolated between the two adjacent three-dimensional point clouds in the original image, and the blank between the two adjacent three-dimensional point clouds is filled, so that the definition and the accuracy of the established three-dimensional model in the jurisdiction are improved.
S3, performing surface vector extraction on the corrected point cloud information to obtain a vector model of the region;
and S4, mapping the vector model of the area by using the aerial view image and the oblique image to obtain a three-dimensional model of the area.
Specifically, a least square method is adopted to fit a plane, points belonging to the same plane are fitted to obtain mathematical equation expression parameters of the plane, a plane equation is listed, and finally a building vector model is obtained. In the method, a building or a certain terrain is initially smoothed by a triangulation network method, and a triangulation network of the surface can be quickly and efficiently constructed by taking key points generated in the execution process of the previous step voxel division method as vertexes of the triangulation network; and then vector fitting is performed on the building or a certain terrain. The building surface is a plane, the intersecting line between the surfaces is a straight line, the created three-dimensional model is smooth, the effect and the quality are good, and the post-pasting is convenient. The intersection lines and surfaces between model surfaces obtained by traditional point cloud creation triangulation are not smooth and are not in accordance with the conditions of actual buildings.
In the application, after a vector model of a certain area of a three-dimensional model is required to be established, angular point coordinates in the vector model are extracted; meanwhile, oblique photography data are processed, including aerial triangulation processing is carried out on oblique photography images, and aerial triangulation results are obtained. Then, finding corresponding points of angular points of the regional vector model on the processed oblique photography, and carrying out absolute orientation; and finally, performing texture mapping on the absolute orientation result of the oblique image on the region vector model to obtain a three-dimensional model of the region. The three-dimensional models of the regions constitute an overall three-dimensional model of the entire jurisdiction.

when the video monitoring system 41 finds that a retention phenomenon of a person in a key area occurs in a district, a second warning signal is sent to the control center 4, and an image of the key area where the person is retained is fed back to the control center 4;
when the video monitoring system 41 finds that the suspicious article leaving phenomenon occurs in the jurisdiction, it sends a third warning signal to the control center 4, and feeds back the image of the area where the suspicious article leaving occurs to the control center 4. The suspicious article leaving monitoring may be performed by presetting a characteristic image of the suspicious article in the control system, and when the video monitoring system 41 determines that a picture similar to the preset image exists in the monitoring process, a third warning signal is sent to the control center 4.
The video monitoring system 41 includes a plurality of cameras in the jurisdiction and is used for performing all-around monitoring on the jurisdiction. The principle of the video monitoring system 41 for judging whether a person intrudes into the forbidden zone is to firstly acquire an unmanned image of the forbidden zone, acquire the image of the forbidden zone in real time, compare and analyze the image acquired in real time and the image acquired in advance, judge whether the images are different and judge whether the phenomenon of intrusion occurs in the forbidden zone. When monitoring different abnormalities, the video monitoring system 41 sends different warning signal signals to the control center 4, so that the control center 4 can realize warning in different modes after receiving the different warning signals. Therefore, the management and control personnel can timely know the abnormal type according to different warnings, and the management and control personnel can timely make a response plan so as to better control the emergency.

It should be noted that the reminding of the wrist band may be different according to different warning signals. For example, when the control center 4 receives the first warning signal, the wrist strap vibrates for 3 seconds at a lower frequency; when the control center 4 receives the second warning signal, the wrist strap vibrates for 3 seconds at a lower frequency and flickers for \8230

the fire fighting abnormity comprises temperature sensing abnormity, smoke sensing abnormity and combustible gas sensing abnormity.
The temperature sensor, the smoke sensor and the combustible gas sensor are usually arranged at specific positions of the district so as to monitor fire fighting in important areas of the district through related sensors. In practical application, the specific position coordinates of the related sensors can be preset in the control center 4, so that when each sensor gives an alarm, the control center 4 can position the alarm position in time according to the preset position, and the management and control personnel can take corresponding measures in the first time.
Example 5
This embodiment will be described only for differences from embodiment 4, and the remaining technical features are the same as those of the above-described embodiment.
The monitoring protection system 3 comprises an operation linkage monitoring system 45, wherein the operation linkage monitoring system 45 divides the district into a plurality of operation areas and endows different operation areas with different safety factors; the method specifically comprises the following steps:
inputting position coordinates of a three-dimensional model of a district; the input position coordinate process is that an operator inputs position coordinates of different points to the control center 4 of the system through an input device;
constructing a boundary of a working area by using position coordinates of a three-dimensional model of the district, and establishing different working areas; the control center 4 constructs a work area boundary according to the input coordinates; the central positions of different areas can be selected firstly in the process of constructing the boundary, and the boundary is constructed step by step according to the outward diffusion of the central positions. In practical applications, it is necessary to construct a fuzzy boundary of the work area. For example, after the work area boundary is constructed, a threshold distance from the work boundary is set, which may be 5m or 10m. And taking the area within the threshold distance as a fuzzy boundary of the operation area, and when an operator matched with the safety coefficient of the fuzzy boundary appears in the fuzzy boundary, the monitoring protection system 3 cannot give an alarm. The design is to reduce false alarm of the monitoring protection system 3 and reduce resource waste.
Different safety factors are given to different operation areas according to different safety levels of the operation areas;
the operation linkage monitoring system 45 gives different grade coefficients to different personnel, including:
acquiring different operator information;
giving different grade coefficients according to different operator information; the safety coefficient of the operation area and the grade coefficient of the operator form a mapping relation;
when the operating region has the operator with the grade coefficient which does not correspond to the safety coefficient of the operating region, the operating linkage monitoring system 45 sends a seventh warning signal to the control center 4, and feeds back the image of the operating region to the control center 4. In a better embodiment, the fuzzy boundary dwell time of the working area is preset in the control center 4, and when an operator with a grade coefficient not corresponding to the safety coefficient of the fuzzy boundary of the working area occurs and the dwell time of the operator exceeds the preset time, the monitoring and protection system 3 sends a seventh warning signal to the control center 4.
The operation linkage monitoring system 45 monitors each operation area, and once an unauthorized person enters an area where the unauthorized person is not allowed to enter, the corresponding alarm response level is immediately triggered, or a distress signal of a field person is received, and the unauthorized person is immediately positioned and highlighted in a three-dimensional scene. Through setting up operation linkage monitoring system 45 can prevent that personnel from unordered flow, helps guaranteeing the security in key area.
The intelligent security command system based on three-dimensional model analysis can send different alarm signals according to the alarm signals of different monitoring systems, so that management and control personnel can timely make response processing according to the different alarm signals, and safety of jurisdictions is guaranteed.
