[0021] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0022] The forest fire locating method, device and electronic device of the present application are described in detail using embodiments below.

[0023] Figure 1A flowchart of a forest fire locating method provided in an embodiment of the present application. It should be noted that the execution subject of the forest fire locating method of this embodiment is a forest fire locating device, which can be a hardware device or software in a hardware device. The hardware device is, for example, a terminal device, a server, etc.

[0024] like Figure 1 As shown, the forest fire locating method proposed in this embodiment includes the following steps:

[0025] S101, tracking the video surveillance visual domain, and synchronizing the visual domain to a three-dimensional geographic information system GIS map, where the GIS map includes points of interest POI.

[0026] It should be noted that this application does not limit the specific method of tracking the video surveillance visual area, and it can be selected according to actual conditions.

[0027] Optionally, for moment t, the posture information of the video surveillance device is obtained, and the posture of the virtual surveillance device on the associated pan / tilt is synchronized according to the posture information, and the line of sight analysis between the viewpoint of the video surveillance device and the corresponding target point is obtained, and based on the line of sight between the viewpoint and the target point, the line of sight line at moment t is obtained, and based on the video data in the line of sight line at moment t, the coordinates of the boundary points of the viewing cone of the video surveillance device are obtained, and the video surveillance visual area is determined based on the coordinates of the boundary points.

[0028] In an embodiment of the present application, after the video surveillance visual domain is acquired, the visual domain can be synchronized to a pre-built three-dimensional geographic information system GIS map.

[0029] The specific process of constructing a three-dimensional geographic information system GIS map proposed in this application is explained below.

[0030] Optionally, map slice data can be obtained from a map file, and based on the map slice data, a map bottom layer can be generated; vector map data and grid data can be obtained from a spatial database, and based on the vector map data and grid data, different spatial layers can be generated; based on the relevant information of the POI, a point, line, and surface vector layer can be generated; monitoring point data of video surveillance can be obtained, and based on the monitoring point data, a video point data layer can be generated; layers can be merged on the map bottom layer in the set order of spatial layer, point, line, and surface vector layer, and video point data layer to obtain a GIS map.

[0031] For example, the process of building a GIS map is as follows: Figure 2As shown in the figure, map slice data (map tile data) can be obtained from the map file to complete the loading of the basic map base map tiles and generate the bottom layer of the map, that is, the three-dimensional tile layer of the Environmental Geographical Information System (EGIS). Satellite and annotation layers and EGIS road network layers can also be generated based on the map slice data, and vector map data and raster data can be obtained from the spatial database, such as Shapefile files, Keyhole Markup Language (KML) files, and Web Map Services (Web Map) that conform to the Open Geospatial Consortium (OGC) standard. WMS) is used to analyze and process vector map data and raster data. Different spatial layers (such as WMS spatial layers) are generated based on vector map data and raster data. Point, line and surface vector layers are generated according to the relevant information of POI. The monitoring point data of video surveillance is obtained from the video information to generate a video point data layer. Ajax asynchronous communication method can be used to keep the vector data operation updated without refreshing the entire page. The business data and video surveillance data related to the monitoring point are stored in the business relationship database. The spatial layer, point, line and surface vector layer and video point data layer are merged on the bottom layer of the map in the set order to obtain a GIS map.

[0032] It should be noted that by constructing a GIS map, on the basis of realizing a two-dimensional (Two Dimensional, referred to as 2D) Internet video surveillance map, by introducing a three-dimensional (Three Dimensional, referred to as 3D) map system to realize the loading and rendering of the three-dimensional model, the three-dimensional and intuitive expression of the monitoring point location is achieved.

[0033] It should be noted that the present application does not limit the specific method for obtaining relevant information of POI, which can be selected according to actual circumstances.

[0034] Optionally, the POIs of cities, counties, towns, and villages at all levels and the name, category, longitude, latitude, altitude and other related information of each POI are obtained through a Python program and with the help of an application program interface (API) opened by a map application.

[0035] For example, data information (data category, data type and data information) of a point of interest (POI) may be obtained, and in order to ensure the accuracy and consistency of the data, the data of the point of interest (POI) needs to be preprocessed, including but not limited to data cleaning, deduplication, format conversion and other operations, to obtain preprocessed point of interest (POI) data information, and based on the preprocessed point of interest (POI) data information, relevant information of the point of interest (POI) is obtained, as shown in Table 1, to construct a relevant information table of the point of interest (POI).

[0037]

[0038] S102: Determine whether there is a suspected fire occurrence point in the visual domain, and in response to the existence of a suspected fire occurrence point in the visual domain, mark the suspected fire occurrence point on the GIS map.

[0039] Among them, the suspected fire occurrence point can be a suspected fire point or a suspected smoke point.

[0040] In an embodiment of the present application, the visible domain can be identified to determine whether there is a suspected fire occurrence point in the visible domain. In response to the existence of a suspected fire occurrence point in the visible domain, the suspected fire occurrence point is marked on the GIS map.

[0041] For example, the longitude and latitude of the suspected fire point can be displayed on the map in real time based on the three-dimensional GIS fire point intelligent positioning linkage device (a visualization device integrating POI points) to mark the suspected fire point on the GIS map.

[0042] S103: Obtain candidate points of interest (POIs) around the suspected fire occurrence point, and determine, from the candidate POIs, a target POI that is closest to the suspected fire occurrence point.

[0043] In an embodiment of the present application, candidate POI points around the suspected fire occurrence point can be searched in the three-dimensional GIS map, and the relative distance between the suspected fire occurrence point and the candidate POI can be determined based on the latitude and longitude information of the candidate POI and the latitude and longitude information of the suspected fire occurrence point. Based on the relative distance between the suspected fire occurrence point and the candidate POI, the target POI closest to the suspected fire occurrence point can be determined from the candidate POI.

[0044] For example, the R-tree spatial index can be used to search for candidate POI points around the suspected fire occurrence point in the three-dimensional GIS map, and the semi-vector Haversine spherical distance formula can be used to determine the relative distance between the suspected fire occurrence point and the candidate POI according to the latitude and longitude information of the candidate POI and the latitude and longitude information of the suspected fire occurrence point. The K-nearest neighbor (KNN) algorithm can be used to determine the target POI closest to the suspected fire occurrence point from the candidate POI according to the relative distance between the suspected fire occurrence point and the candidate POI.

[0045] S104: According to the target POI and the suspected fire occurrence point, the location description information of the suspected fire occurrence point is sent to the terminal device associated with the target POI.

[0046] In an embodiment of the present application, after the target POI and the suspected fire occurrence point are acquired, the location description information of the suspected fire occurrence point may be sent to a terminal device associated with the target POI based on the target POI and the suspected fire occurrence point.

[0047] Optionally, the relative position information between the target POI and the suspected fire occurrence point can be obtained, and the positioning description information of the suspected fire occurrence point is generated based on the address description information and relative position information of the target POI, and the positioning description information of the suspected fire occurrence point is sent to the terminal device.

[0048] The present application provides a forest fire locating method, which tracks the visual domain of video surveillance and synchronizes the visual domain to a three-dimensional geographic information system (GIS) map, including points of interest (POIs) on the GIS map, determines whether there is a suspected fire occurrence point in the visual domain, marks the suspected fire occurrence point on the GIS map in response to the existence of the suspected fire occurrence point in the visual domain, obtains candidate points of interest (POIs) around the suspected fire occurrence point, determines the target POI closest to the suspected fire occurrence point from the candidate POIs, and sends the location description information of the suspected fire occurrence point to the terminal device associated with the target POI based on the target POI and the suspected fire occurrence point. The present application combines video surveillance technology with three-dimensional GIS technology, generates the location description information of the suspected fire occurrence point based on the target POI and the suspected fire occurrence point, enables protection personnel to quickly and accurately locate the fire point, and improves the efficiency and accuracy of forest fire monitoring and emergency response.

[0049] As a possible implementation, Figure 3 As shown, based on the above embodiment, the specific process of tracking the video surveillance visual area in the above steps includes the following steps:

[0050] S301. At time t, obtain the posture information of the video monitoring device, and synchronize the posture of the virtual monitoring device on the associated pan / tilt head according to the posture information.

[0051] The video surveillance device may be a camera.

[0052] The position information of the video surveillance device includes but is not limited to the horizontal rotation angle of the video surveillance device, that is, the azimuth angle, and the vertical rotation angle of the video surveillance device, that is, the pitch angle.

[0053] Optionally, the three-dimensional surface can be read to determine the preset position of the associated pan / tilt head, and for time t, the azimuth angle β=t*Vk+ε and the pitch angle α=t*Vv+δ of the video surveillance device can be obtained, wherein β is the azimuth angle, α is the pitch angle, Vk is the horizontal rotation speed of the video surveillance device, Vv is the vertical rotation speed of the video surveillance device, ε is the horizontal rotation angle of the preset position, and δ is the vertical rotation angle of the preset position.

[0054] It should be noted that when the video surveillance device is a real camera and the virtual surveillance device is a virtual camera, the real camera and the virtual camera are synchronized in movement to keep their shooting focal length, angle, position and rotation orientation consistent. Sensor tracking technology, real-time graphic recognition technology and infrared detection technology are used to synchronize the virtual camera with the real camera in real time. The virtual camera tracks the left and right swing, up and down pitch, camera rotation and lens aperture change of the real camera head.

[0055] S302: Obtain a line of sight analysis between the viewpoint of the video surveillance device and the corresponding target point, and obtain a line of sight line at time t according to the line of sight between the viewpoint and the target point.

[0056] Optionally, a line of sight (LOS) algorithm may be used to obtain a line of sight analysis between a viewpoint of a video surveillance device and a corresponding target point, thereby obtaining a line of sight situation between the viewpoint and the target point.

[0057] In an embodiment of the present application, in response to the viewpoint and the target point being in line of sight, the real-time line of sight route at time t is obtained as the line of sight route at time t; in response to the viewpoint and the target point not being in line of sight, the existing line of sight route before time t is obtained as the line of sight route at time t.

[0058] In the embodiment of the present application, in response to the viewpoint being in line of sight with the target point, the real-time line of sight at time t is synchronized with the pan / tilt, and the existing line of sight before time t is deleted.

[0059] It should be noted that after obtaining the line of sight at time t, the three-dimensional surface is refreshed, that is, the line of sight is refreshed every time it rotates by an angle β on the three-dimensional terrain. A single line of sight can be rotated in all directions. For a specified line of sight, when performing an interval refresh operation, the line of sight of the previous angle that has been displayed is deleted and the line of sight of the new angle is added, and then the three-dimensional scene is refreshed.

[0060] S303: Obtain the coordinates of the boundary points of the viewing cone of the video surveillance device according to the video data in the line of sight at time t, and determine the video surveillance visual area based on the coordinates of the boundary points.

[0061] In an embodiment of the present application, the coordinates of the boundary points of the viewing cone of the video surveillance device can be obtained according to the video data in the line of sight at time t, and the video surveillance visual area can be determined based on the coordinates of the boundary points.

[0062] Therefore, the present application obtains the posture information of the video surveillance device at time t, and synchronizes the posture of the virtual surveillance device on the associated pan / tilt according to the posture information, obtains the line of sight analysis between the viewpoint of the video surveillance device and the corresponding target point, obtains the line of sight at time t according to the line of sight between the viewpoint and the target point, obtains the boundary point coordinates of the visual cone of the video surveillance device according to the video data in the line of sight at time t, and determines the video surveillance visual field based on the boundary point coordinates. Therefore, the present application determines the video surveillance visual field by tracking the video surveillance visual field, laying the foundation for the subsequent accurate and rapid positioning of forest fires.

[0063] As a possible implementation, Figure 4 As shown, based on the above embodiment, the specific process of sending the location description information of the suspected fire occurrence point to the terminal device associated with the target POI according to the target POI and the suspected fire occurrence point in the above steps includes the following steps:

[0064] S401: Obtain relative position information between a target POI and a suspected fire occurrence point.

[0065] Optionally, the relative position information between the target POI and the suspected fire occurrence point may be acquired according to the latitude and longitude information of the target POI and the latitude and longitude information of the suspected fire occurrence point.

[0066] S402: Generate location description information of the suspected fire occurrence point based on the address description information and relative position information of the target POI.

[0067] In the embodiment of the present disclosure, based on the address description information and relative position information of the target POI, the address description information of the suspected fire occurrence point is generated, the map information including the suspected fire occurrence point is obtained, and the positioning description information is generated according to the address description information and the map information.

[0068] For example, the map information including the suspected fire occurrence point is longitude 102.746599 and latitude 24.302806. The map information is used to determine that the suspected fire occurrence point is located at Hongta Mountain in Yuxi City, Yunnan Province, and based on the address description information and relative position information of the target POI, the address description information of the suspected fire occurrence point is generated as "XX Farmhouse, Datun Village, Jiangchuan District, Yuxi City". Then, based on the address description information and map information, the location description information of the suspected fire occurrence point is generated as "5km northeast of the back mountain of XX Farmhouse, Datun Village, Jiangchuan District, Yuxi City, Yunnan Province". The above data is for example only and is not real data.

[0069] S403: Send the location description information of the suspected fire occurrence point to the terminal device.

[0070] In an embodiment of the present application, before sending the location information of the suspected fire occurrence point to the terminal device associated with the target POI, the target administrative area to which the target POI belongs can be determined based on the map administrative division information, and the contact information of the protection personnel corresponding to the target administrative area can be obtained.

[0071] For example, if the location description information is "5km northeast of the back mountain of XX Farmhouse in Datun Village, Jiangchuan District, Yuxi City, Yunnan Province", by obtaining the contact information of the protection personnel, the location description information can be sent to the terminal device associated with the protection personnel in Datun Village. Since the protection personnel are local villagers and clearly know the location of XX Farmhouse, they can quickly rush to the location of the suspected fire point to conduct fire point verification or early fire disposal work.

[0072] Therefore, the present application obtains the relative position information between the target POI and the suspected fire occurrence point, generates the positioning description information of the suspected fire occurrence point based on the address description information and the relative position information of the target POI, and sends the positioning description information of the suspected fire occurrence point to the terminal device. The present application generates the positioning description information of the suspected fire occurrence point based on the address description information and the relative position information of the target POI, and through the geographic reference system familiar to the protection personnel, the location of the fire point can be determined more quickly and accurately, which solves the problem that it is difficult for protection personnel to accurately locate the fire point during the fire point verification process, and improves the efficiency of fire monitoring and emergency response.

[0073] In an embodiment of the present application, operations of controls on the display interface of the GIS map can be monitored to obtain the identifier of the control being operated and the content of the operation, and an operation instruction can be generated based on the identifier of the control and the content of the operation. In response to the operation instruction being an interface update instruction, the current display content of the display interface is updated based on the interface update instruction. In response to the operation instruction being a configuration instruction for a video surveillance device, the configuration parameters of the video surveillance device are determined based on the configuration instruction, and the video surveillance device is synchronously configured based on the configuration parameters.

[0074] For example, the display interface of the GIS map is designed to meet the basic functional needs of users and is based on the forest and grassland fire prevention and extinguishing business applications, allowing users to quickly get started and master the specific operations of video surveillance and monitoring point layout, and quickly identify the location of the video fire point and the surrounding area. Figure 5 As shown, the controls of the display interface of the GIS map include but are not limited to fire risk prevention controls, basic data controls, monitoring and early warning controls, fire situation assessment controls, emergency response controls and auxiliary analysis controls. Users can view surveillance videos and analyze the camera's visible area through the tools in the toolbar. The toolbox in the upper right corner provides a video surveillance point addition function. Operate the button and click the map to complete the site selection of the map video surveillance point. Click the video surveillance on the map, and a monitoring information entry box will pop up on the right to set the camera parameters. Configure the video surveillance device synchronously according to the configuration parameters, such as: the layout position, layout height, visible distance, direction angle, pitch angle, horizontal field of view, and vertical field of view of the video surveillance device (camera). Determine the display color of the video surveillance visible area and the display color of the invisible area, and set the properties of the pop-up box. The surveillance video playback window is set at the center point of the current view of the map. It also provides the zoom in and out full screen and video "picture-in-picture" functions of the view window, and updates the current display content of the display interface according to the interface update instruction.

[0075] Therefore, the video surveillance range and field of view analysis range of the present application rotate synchronously with the front-end video surveillance equipment, realizing dynamic field of view analysis on the three-dimensional GIS map. At the same time, by overlaying the point of interest POI data on the map, it assists in identifying the video surveillance location address to a great extent. Once a suspected fire point is found, the fire direction and fire point location can be accurately identified, which is convenient for protection personnel and rescue teams to rush to the scene in time to carry out work, solving the problem of accurately locating the fire point during the fire point verification process, and improving the efficiency and accuracy of fire monitoring and emergency response.
