[0046] The following describes a method for processing forest area geographic information provided by an embodiment of the present application.

[0047] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of a method for processing forest area geographic information provided in an embodiment of the present application. Figure 3 As shown, the method for processing forest area geographic information includes the following steps.

[0048] S301, receiving a forest area surveying and mapping dataset for a target forest area from the user terminal.

[0049] S302, creating a forest area model and a corresponding forest stand database of the target forest area according to the forest area surveying and mapping data set, and sending the forest area model to the user terminal, wherein the forest stand database includes at least one first forest stand data and a second forest stand data.

[0050] The forest area surveying and mapping dataset includes multiple location information uploaded by the positioning tag and remote sensing image data collected by the remote sensing module. The location information may specifically be the coordinates of the location of the aircraft, and the positioning tag may include a Beidou positioning system, based on which the coordinates may be determined. The remote sensing image data may specifically be a remote sensing image taken by the aircraft's sensor at the above coordinates, and the remote sensing image is composed of pixels.

[0051] The first forest stand data characterizes the topographic conditions of the target forest area, such as slope, soil moisture or elevation, etc.; the second forest stand data characterizes the growth conditions of the target forest area, such as tree species, tree age or biomass, etc.

[0052] The forest area model can be a three-dimensional model of each area that the aircraft flies through, and the user can rotate or zoom in on the three-dimensional model to view the target forest area. The forest area model can also be a two-dimensional model of each area that the aircraft flies through, and the user can click on any area of ​​the two-dimensional model to view the remote sensing image data collected by the aircraft in the area.

[0053] S303, receiving a rescue instruction for the target forest area in the forest area model from the user terminal.

[0054] S304: Control the aircraft to collect fire data of the target forest area according to the rescue request; and determine the fire type of the target forest area based on the fire data and the forest stand database.

[0055] The rescue instruction is used to indicate that there is a fire in the target forest area. When the user finds an abnormality in the forest area model, the user can send a rescue instruction to the server through the user terminal to inform the server that there is a fire in the target forest area and request the server to perform further processing.

[0056] Among them, when the server receives the rescue command sent by the user terminal, it can control the aircraft to fly to the target forest area and use the sensors and cameras it carries to collect fire data. The fire data is used to characterize the fire conditions in the target forest area and can be data that affects the fire, such as wind direction, wind speed, burning time, etc.

[0057] S305: Create rescue tool information for the target forest area based on the fire type and the at least one second forest stand data.

[0058] S306: Send the rescue tool information to the user terminal.

[0059] Among them, the rescue tool information can be specific to various fire-fighting equipment, such as fire extinguishers, fire hydrants or smoke masks, etc. The fire types can include surface fires, forest crown fires, and underground fires. Different fire types require different fire-fighting equipment. For example, when the fire type is a surface fire, the required fire-fighting equipment may be a fire-fighting water gun, fire-fighting bombs or sand covering tools; when the fire type is a forest crown fire, the required fire-fighting equipment may be a helicopter or a dry powder fire extinguishing agent; when the fire type is an underground fire, the required fire-fighting equipment may be an underground fire detector or an excavator.

[0060] It can be seen that in this example, the server constructs a forest area model and a forest stand database through the aircraft. When a fire occurs, the server determines the rescue tools corresponding to the fire rescue based on the forest stand database and fire data, and informs the user to carry the rescue tools, so that the rescue tools are highly adapted to the fire situation, avoiding users from carrying unnecessary equipment or missing necessary equipment, thereby improving rescue efficiency and improving rescue results.

[0061] In a possible embodiment, determining the fire type of the target forest area based on the fire data and the forest stand database includes: determining the surface fire risk index of the target forest area based on the first forest stand data and the fire data; determining the crown fire risk index of the target forest area based on the second forest stand data and the fire data; determining the underground fire risk index of the target forest area based on the first forest stand data, the second forest stand data and the fire data; determining the fire type based on the highest value among the surface fire risk index, the crown fire risk index, and the underground fire risk index.

[0062] Among them, the surface fire risk index can indicate the probability that the fire type in the target forest area is a surface fire. The characteristic of surface fire is that it mainly burns in the dead branches and leaves layer on the ground, and the spread speed is relatively slow, so more consideration needs to be given to the factors affecting the surface; the crown fire risk index can indicate the probability that the fire type in the target forest area is a crown fire. The characteristic of crown fire is that the flame spreads in the canopy layer, spreads quickly, and is highly destructive, so more consideration needs to be given to the factors affecting the canopy; the underground fire risk index can indicate the probability that the fire type in the target forest area is an underground fire. The characteristic of underground fire is that it spreads below the surface and lasts for a long time, so more consideration needs to be given to the factors affecting the underground.

[0063] Among them, the fire type needs to be determined based on the maximum value of the surface fire risk index, crown fire risk index, and underground fire risk index. For example, when the surface fire risk index is 3, the crown fire risk index is 6, and the underground fire risk index is 1, the crown fire risk index is the largest. Correspondingly, the fire type in the target forest area is crown fire.

[0064] Specifically, the fire data includes fire range, wind direction, wind speed, relative humidity, and burning time, the first forest stand data includes soil moisture and slope factor, and the determining of the surface fire risk index of the target forest area based on the first forest stand data and the fire data includes: determining the surface fire risk index based on the fire range, the wind direction, the wind speed, the relative humidity, the burning time, the soil moisture, and the slope factor, as follows:

[0065]

[0066] Among them, R S is the surface fire risk index, k 1 is the first adjustment coefficient, k 2 is the second adjustment coefficient, A is the fire range, W D is the wind direction, W S is the wind speed, H R is the relative humidity, T is the burning time, M S is the soil moisture and S is the slope factor.

[0067] The fire range indicates the area where the fire spreads on the surface. The larger the fire range, the higher the surface fire risk index. The wind direction indicates the direction of the wind, usually expressed in degrees, that is, W. DIt can be specifically the angle between the wind and the horizontal direction; wind speed indicates the speed of the wind. The higher the wind speed, the higher the surface fire risk index; relative humidity indicates the ratio of the water vapor content in the air to the saturated water vapor content, usually expressed as a percentage (%). The higher the relative humidity, the lower the surface fire risk index; burning time indicates the length of time the fire lasts. The longer the burning time, the higher the surface fire risk index; slope factor indicates the degree of inclination of the ground; k 2 Used to adjust the relative humidity impact, k 1 Used to adjust the impact of other factors mentioned above, k 1 and k 2 The specific value of needs to be obtained based on historical data, model testing or expert consultation.

[0068] In this way, the probability of surface fire can be determined by taking into account the fire range, wind direction, wind speed, relative humidity, burning time and inclination, which helps to further determine the type of fire.

[0069] Specifically, the second forest stand data includes a vegetation type factor and a density factor, and the determining of the crown fire risk index of the target forest area based on the second forest stand data and the fire data includes: determining the crown fire risk index based on the fire range, the wind direction, the wind speed, the relative humidity, the burning time, the vegetation type factor, and the density factor, as follows:

[0070] R C =k 3 ×A×(1+sinW D )×W S ×(1-H R )×T×V×D

[0071] Among them, R c is the crown fire risk index, k 3 is the third adjustment coefficient, V is the vegetation type factor, and D is the density factor.

[0072] Among them, the vegetation type factor indicates the flammability of vegetation in the target forest area. The higher the flammability of vegetation in the target forest area, the larger the vegetation type factor and the higher the crown fire risk index; the density factor identifies the vegetation density or vegetation coverage of the target forest area. The higher the vegetation density or vegetation coverage, the larger the density factor and the higher the crown fire risk index. 3 Used to adjust the impact of the above factors and fire data, k 3 The specific value of needs to be obtained based on historical data, model testing or expert consultation.

[0073] In this way, the probability of a crown fire can be determined by taking into account fire extent, wind direction, wind speed, relative humidity, burning time, vegetation type, and vegetation density, which helps to further determine the type of fire.

[0074] Specifically, the determining the underground fire risk index of the target forest area based on the first forest stand data, the second forest stand data and the fire data includes: determining the crown fire risk index based on the fire range, the wind direction, the wind speed, the relative humidity, the burning time, the vegetation type factor, and the density factor, as follows:

[0075]

[0076] Among them, R U is the crown fire risk index, k 4 is the fourth adjustment coefficient, k 5 is the fifth adjustment coefficient.

[0077] Among them, k 5 Used to adjust the relative humidity impact, k 4 Used to adjust the impact of other factors mentioned above, k 4 and k 5 The specific value of needs to be obtained based on historical data, model testing or expert consultation.

[0078] Thus, the probability of underground fire can be determined by taking into account fire extent, wind speed, relative humidity, burning time, and vegetation density, which helps to further determine the type of fire.

[0079] It can be seen that in this example, the server can obtain a surface fire risk index based on the fire data and the first forest stand data, obtain a canopy fire risk index based on the second forest stand data, and obtain an underground fire risk index based on the first forest stand data and the second forest stand data, thereby determining the fire type in the target forest area based on the above risk index, which helps to further determine the rescue tools corresponding to the fire rescue, making the rescue tools highly adapted to the fire situation, avoiding users from carrying unnecessary equipment or missing necessary equipment, thereby improving rescue efficiency and improving rescue results.

[0080] In a possible embodiment, the rescue tool information includes target rescue equipment, and the at least one second forest stand data also includes average tree height, forest stand density and tree species composition, and the rescue tool information for the target forest area is created based on the fire type and the at least one second forest stand data, including: determining a first rescue equipment based on the fire type and the average tree height; determining a second rescue equipment from the first rescue equipment based on the tree species composition; and determining the target rescue equipment from the second rescue equipment based on the forest stand density.

[0081] The first rescue equipment includes air rescue equipment, surface rescue equipment and / or underground rescue equipment. The air rescue equipment can be specifically firefighting equipment for high-altitude operations such as helicopters or drones. The surface rescue equipment can be specifically firefighting equipment for ground operations such as fire trucks, water pumps and fire extinguishers. The underground rescue equipment can be underground detection radars, underground water pumps and ventilation equipment. The average tree height can represent the height of vegetation in the target forest area. The height of vegetation may have an impact on the development of the fire. For example, when the fire type is a surface fire, the first rescue equipment can be a surface rescue equipment. The average tree height is 25 meters, and the fire may develop into a canopy fire. At this time, the first rescue equipment can also add air rescue equipment to deal with this situation.

[0082] Among them, the fire extinguishing agent material of the second rescue equipment is related to the tree species composition. The fire extinguishing agent material specifically includes water-based fire extinguishing agent, foam fire extinguishing agent, dry powder fire extinguishing agent, carbon dioxide fire extinguishing agent, clean fire extinguishing agent or special fire extinguishing agent, etc. The tree species composition can specifically be the coverage rate of various vegetation types. The server can determine the fire extinguishing agent material of the rescue equipment according to the tree species composition. For example, when the coverage rate of the vegetation type exceeds a certain proportion threshold, the server can select the fire extinguishing agent material for the rescue equipment of the vegetation type. Specifically, the proportion threshold is 20%. In the target forest area, the tree species composition is a coniferous forest with a coverage rate of 52%, a shrubbery with a coverage rate of 35%, and a grassland vegetation with a coverage rate of 13%. Then, the rescue equipment with the fire extinguishing agent material of water-based fire extinguishing agent and foam fire extinguishing agent can be selected from the first rescue equipment as the second rescue equipment.

[0083] Among them, the power of the target rescue equipment is positively correlated with the forest stand density. The forest stand density can indicate the degree of crowding between vegetation in the target forest area, which is specifically determined by the ratio between the average distance between vegetation and the average crown width. The forest stand density can be expressed in stages, specifically low density, medium density and high density, corresponding to different forest stand density intervals, and the server can determine the rescue equipment based on the forest stand density. For example, when the forest stand density in the target forest area is low density, the rescue equipment can choose portable and manual types with lower power; when the forest stand density in the target forest area is medium density, the rescue equipment can choose fire trucks with higher power; when the forest stand density in the target forest area is high density, the rescue equipment can choose large fire trucks with higher power.

[0084] It can be seen that in this example, the rescue equipment is preliminarily determined by the fire type and average height, and the fire extinguishing agent material is determined by the tree species composition to further determine the rescue equipment. Finally, the final required rescue equipment is determined according to the forest stand density, so that the rescue equipment is highly adapted to the fire situation, avoiding users from carrying unnecessary equipment or missing necessary equipment, thereby improving rescue efficiency and improving rescue results.

[0085] In a possible embodiment, the user terminal includes a first user terminal and a second user terminal, and the receiving of rescue instructions from the user terminal for the target forest area in the forest area model includes: receiving real-time image data and real-time position information from the aircraft; and, retrieving corresponding remote sensing image data based on the real-time position information; and, comparing the real-time image data with the remote sensing image data, and if the real-time image data is inconsistent with the remote sensing image data, sending an abnormal signal to the first user terminal, and receiving a rescue instruction generated by the first user terminal in response to a user's confirmation request for the abnormal signal; or receiving a rescue request generated by the second user terminal in response to a user's start-up operation information for fire rescue, and the rescue request includes the user location information of the second user terminal.

[0086] Among them, the user corresponding to the first user terminal is used to command and dispatch the user corresponding to the second user terminal device. The first user terminal can be specifically a control platform computer or a mobile phone, and the corresponding user can be a command and dispatch personnel. The second user terminal can be specifically a mobile phone or a smart watch, and the corresponding user can be an on-site rescue personnel.

[0087] Among them, the rescue command can be initiated by the command and dispatch personnel. For example, when the aircraft is patrolling in the target forest area, it will send the real-time position and real-time picture to the server. The server can retrieve the remote sensing image data collected by the aircraft at the real-time position before, and compare and analyze the real-time picture and the remote sensing image data (specifically, the comparison can be performed through deep learning, feature matching or image difference algorithms). If there is a difference between the real-time picture and the remote sensing image data, the real-time picture needs to be sent to the first user terminal so that the command and dispatch personnel can view the real-time picture on the display screen of the first user terminal and perform operations. Please refer to Figure 4 , Figure 4 Schematic diagram of an interface for a first user terminal to send a rescue request provided by an embodiment of the present application. Figure 4 As shown, a geographical model of a target forest area and a real-time position of the aircraft in the target forest area (i.e., a red dot in the figure) are displayed on a first display screen of a first user terminal. When the server detects that the real-time image of the position changes, a first real-time image 401 is displayed on the first display screen, and a first confirmation window 402 (i.e., an abnormal signal) is displayed on the first display screen. The first confirmation window 402 includes a confirmation button and a cancel button. The first confirmation window 402 is used for command and dispatch personnel to confirm a fire. The command and dispatch personnel can click on the first real-time image 401 to enlarge and view the image, and can also click on the confirmation button in the first confirmation window 402 to confirm that there is a fire at the position or click on the cancel button to confirm that there is no fire at the position. When the command and dispatch personnel click on the confirmation button, the first user terminal sends a rescue instruction to the server.

[0088] In addition, the first user terminal can also initiate a rescue command on its own. For example, see Figure 5a and 5b , Figure 5a and 5b is another interface diagram of a first user terminal sending a rescue request provided by an embodiment of the present application. The command and dispatch personnel double-click any position (for example, Figure 5a The first user terminal responds to the double-click operation and displays a first pop-up window 501. The first pop-up window 501 displays "Do you want to view?". The command and dispatch personnel can choose to issue a command to the aircraft so that the aircraft flies to the location and collects the corresponding real-time picture. When the aircraft collects the real-time picture, Figure 5b As shown, a second pop-up window 502 is displayed on the first display screen, and the second pop-up window 502 includes a second real-time picture 503 and a second confirmation window 504. The second confirmation window 504 displays "whether to conduct rescue", and the second confirmation window 504 includes a yes button and a no button for the command dispatcher to choose whether to initiate a rescue command. It should be noted that the command dispatcher can click Figure 5a Click outside the first pop-up window 501 to exit viewing.

[0089] The rescue order may also be initiated by on-site rescue personnel. Figure 6a and Figure 6b , Figure 6a and Figure 6b Schematic diagram of an interface for a second user terminal to initiate a rescue request provided by an embodiment of the present application. Figure 6a As shown, on-site rescue personnel can observe the forest geographical model of the target forest area through the second display screen of the smart watch, which can be achieved by sliding or zooming in. The second display screen includes the user's current location information (i.e. Figure 6a When the rescue workers on the scene find a fire, they can click "Call" on the second display to call the rescue center to report the fire. Or when the rescue workers on the scene find themselves surrounded by fire or encounter other emergencies, they can click "SOS" on the second display to send their location to the rescue center, so that the rescue center can immediately know that the rescue workers are in danger and deal with them in time according to the rescue workers' location. In addition, Figure 6bAs shown, after the on-site rescue personnel clicks "Send", the second display screen will display a prompt pop-up window 601, and the content of the prompt pop-up window 601 is "Sent successfully, waiting for response...". After the rescue center responds, the prompt pop-up window 601 disappears, and the on-site rescue personnel can confirm whether the rescue center has received the alarm based on the prompt pop-up window 601, thereby ensuring the safety of the rescue personnel. It should be noted that the on-site rescue personnel can also click "More" in the second display screen to realize other functions, such as controlling the aircraft to a specified location to collect on-site pictures.

[0090] It can be seen that in this example, a rescue request can be initiated through the first user terminal, and a rescue request can also be initiated through the second user terminal. The initiation of diversified rescue requests enables the fire to be discovered in time, helps the server to determine the fire rescue tools in time, improves the rescue efficiency, and improves the rescue effect.

[0091] It should be noted that the server may send the rescue tool information to the user terminal to the first user terminal. For details, see Figure 7 , Figure 7 Schematic diagram of a rescue tool information interface provided by an embodiment of the present application. Figure 7 As shown, the command and dispatch personnel can view the specific rescue tool interface 701, and the command and dispatch personnel can click "modify" according to their own judgment to modify it, or click "confirm" to send the rescue tool information to the on-site rescue personnel through the server. Figure 8 As shown, Figure 8 is another interface diagram of rescue tool information provided by an embodiment of the present application. The rescue tool information can be directly displayed on the display screen of the second user terminal, and the on-site rescue personnel can view more rescue tools by sliding and other operations, and prepare corresponding rescue tools according to the rescue tool information. Figure 8 As shown, in the display screen of the second user terminal, the tool information can be presented in red font to prominently remind the on-site rescue personnel of the tools they need to carry. When the on-site rescue personnel prepare the corresponding tools according to the tool information, the on-site rescue personnel can click on the tool information to switch it to green font to confirm that the tool is ready. For example, when the on-site rescue personnel carry a fire axe, they can click on "fire axe" and the "fire axe" switches from red font to green font. In this way, the server sends the rescue tool information to the command and dispatch personnel for interactive confirmation, and sends the rescue tool information to the on-site rescue personnel, so that the on-site rescue personnel can accurately carry the corresponding tools according to the rescue tool information, so that the rescue equipment is highly adapted to the fire situation, avoiding the on-site rescue personnel from carrying unnecessary equipment or missing necessary equipment, thereby improving the rescue efficiency and the rescue effect.

[0092] In a possible embodiment, the fire data includes fire location information, and the method further includes: obtaining current location information of the second user terminal; creating a forward path based on the fire location information, the current location information, and the forest area model, and sending it to the first user terminal; generating forward guidance information based on the forward path; and sending the forward guidance information to the second user terminal.

[0093] Among them, the fire location information can specifically be a set of coordinates where the fire occurred, that is, the coordinates corresponding to the location where the fire occurred; the server combines the forest area geographical model, takes into account the actual growth conditions of the target forest area, the location of on-site rescue personnel and the location of the fire, to ensure that on-site rescue personnel can reach the fire scene safely and efficiently.

[0094] The server generates a forward path based on the fire location, the location of the on-site rescue personnel, and the terrain of the target forest area. The forward path is the optimal path generated by combining multiple factors such as the forward time, terrain features, or water source location. The forward path can be displayed on the first user terminal, see Fig. 9 , Fig. 9 : is a schematic diagram of an interface of a forward path provided by an embodiment of the present application. When there are multiple second user terminals, the location information, forward path, and fire location (such as the location of the firefighters on the scene corresponding to each second user terminal) can be seen on the display screen of the first user terminal. Fig. 9 The red dot in the middle), each on-site rescuer corresponding to the second user terminal has a corresponding forward path, which is distinguished by color on the display screen of the first user terminal, and each forward path has corresponding path information, for example, the remaining distance of the yellow forward path is 10km, the current speed is 4m / s, and the estimated time is 30min, so that the command and dispatch personnel can understand the situation of the forward path, and the command and dispatch personnel can click "<<" to view more relevant information about the forward path, such as obstacle information, terrain information, and the status information of the on-site rescue personnel. In this way, the forward path is visualized on the display screen of the first user terminal, so that the command and dispatch personnel can observe the rescue situation of the on-site rescue personnel in real time and in a timely manner, thereby improving the efficiency and effect of fire rescue.

[0095] The forward guidance information includes direction adjustment indication information and roadblock prompt information. Since the growth environment in the forest area is relatively complex, the direction adjustment indication information can be used to guide the on-site rescue personnel to adjust the forward direction and move toward the fire area in the target forest area; since the roadblock prompt information can be used to remind the on-site rescue personnel of the roadblocks they encounter during their forward movement.

[0096] There are many ways to output the forward guidance information. For example, when the second user terminal is a smart watch, the smart watch may include a display screen and a speaker. The forward guidance information may be displayed on the display screen of the smart watch and the audio information of the forward guidance information may be played through the speaker of the smart watch. Fig.10 , Fig.10 Schematic diagram of an interface of forward guidance information provided by an embodiment of the present application. Fig.10 As shown, the display screen can display the complete forward path (red route), the user's current position (yellow triangle), the forward destination (red dot), and the roadblock information (blue dot). The user can click the blue dot to view the roadblock information there, and the smart watch can compare the user's current position and the forward path, and play audio such as "go straight for ten meters and turn right" through the speaker to remind the user to adjust the forward direction. In addition, the output method of the forward guidance information can also include performing a vibration operation through the vibration sensor of the smart watch to remind the user to pay attention to the smart watch or performing an electrical stimulation operation through the electrical stimulation sensor of the smart watch to remind the user to pay attention to the smart watch. For example, when the user's position deviates, the smart watch can vibrate or perform electrical stimulation to remind the user that the position is wrong and adjust it in time. In this way, the on-site rescue personnel can go to the fire rescue in time according to the forward guidance information, which improves the reliability of fire rescue and improves the efficiency and effect of fire rescue.

[0097] It can be seen that in this example, the server can create a forward path based on location information and geographic information, display the forward path to the user, and guide the user forward according to the forward path, so that the user can reach the fire location in a timely and efficient manner, thereby improving rescue efficiency and improving rescue results.
